Kakunaga S., Ikeda W., Itoh S., Deguchi-Tawarada M., Ohtsuka T., Mizoguchi A., Takai Y.. Nectins are Ca2+-independent immunoglobulin-like cell-cell adhesion molecules and comprise a family of four members. At the mossy fiber terminals of hippocampus, nectin-1 and nectin-3 localize at the presynaptic and postsynaptic sides of synaptic junctions, respectively, and their trans-interactions play a role in formation of synapses in cooperation with N-cadherin. Nectins are associated with the actin cytoskeleton through afadin, a nectin- and actin-filament-binding protein. Five nectin-like molecules (Necls) which have domain structures similar to those of nectins have been identified and here we characterize Necl-1/TSLL1/SynCAM3, from now on referred to as Necl-1. Tissue distribution analysis showed that Necl-1 was specifically expressed in the neural tissue. Immunofluorescence and immunoelectron microscopy revealed that Necl-1 localized at the contact sites among axons, their terminals, and glia cell ...

We describe a high-throughput screening system to detect interactions between leucocyte surface proteins, taking into account that these interactions are usually of very low affinity. The method involves producing the extracellular regions of leucocyte proteins with tags so that they can be bound to nanoparticles to provide an avid reagent to screen over an array of 36 similar proteins immobilized using the Proteon XPR36 with detection by surface plasmon resonance. The system was tested using established interactions that could be detected without spurious binding. The ability to detect new interactions was shown by identifying a new interaction between carcinoembryonic antigen-related cell adhesion molecule 1 and carcinoembryonic antigen-related cell adhesion molecule 8.

Cell adhesion molecule that plays a role in neuronal self-avoidance. Promotes repulsion between specific neuronal processes of either the same cell or the same subtype of cells. Mediates within retinal amacrine and ganglion cell subtypes both isoneuronal self-avoidance for creating an orderly dendritic arborization and heteroneuronal self-avoidance to maintain the mosaic spacing between amacrine and ganglion cell bodies (PubMed:10925149). Receptor for netrin required for axon guidance independently of and in collaboration with the receptor DCC. In spinal chord development plays a role in guiding commissural axons projection and pathfinding across the ventral midline to reach the floor plate upon ligand binding (PubMed:18585357, PubMed:19196994). Enhances netrin-induced phosphorylation of PAK1 and FYN (PubMed:15169762).

A protein encoded by a gene in band 22 of the long arm of human chromosome 21. The gene contains multiple exons which allow multiple mRNAs to be transcribed by alternative splicing (q.v.). The transcripts are differentially expressed in different substructures of the adult brain. The DSCAM is a member of the immunoglobulin domain superfamily (q.v.). These isoforms may be involved in the patterning of neural networks by selective adhesions between axons. See innate immunity. ...
Synaptic cell adhesion molecules (SynCAMs) are crucial for synapse formation and plasticity. However, we have previously demonstrated that SynCAMs are also required during earlier stages of neural circuit formation because SynCAM1 and SynCAM2 (also known as CADM1 and CADM2, respectively) are important for the guidance of post-crossing commissural axons. In contrast to the exclusively homophilic cis-interactions reported by previous studies, our previous in vivo results suggested the existence of heterophilic cis-interactions between SynCAM1 and SynCAM2. Indeed, as we show here, the presence of homophilic and heterophilic cis-interactions modulates the interaction of SynCAMs with trans-binding partners, as observed previously for other immunoglobulin superfamily cell adhesion molecules. These in vitro findings are in agreement with results from in vivo studies, which demonstrate a role for SynCAMs in the formation of sensory neural circuits in the chicken embryo. In the absence of SynCAMs, ...

Background: Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), an immunoglobulin (Ig)-related glycoprotein, serves as cellular receptor for a variety of Gram-negative bacterial pathogens associated with the human mucosa. In particular, Neisseria gonorrhoeae, N. meningitidis, Moraxella catarrhalis, and Haemophilus influenzae possess well-characterized CEACAM1-binding adhesins. CEACAM1 is typically involved in cell-cell attachment, epithelial differentiation, neovascularisation and regulation of T-cell proliferation, and is one of the few CEACAM family members with homologues in different mammalian lineages. However, it is unknown whether bacterial adhesins of human pathogens can recognize CEACAM1 orthologues from other mammals.,br /,Results: Sequence comparisons of the amino-terminal Ig-variable-like domain of CEACAM1 reveal that the highest sequence divergence between human, murine, canine and bovine orthologues is found in the β-strands comprising the bacteria-binding ...
Our previous in vitro data suggested that CEACAM1 is involved in angiogenesis. This is supported by a recent proteomic screen for cell membrane components expressed in newly formed tumor vessels and the fact that CEACAM1 expression is upregulated in synergy with other angiogenic factors in cardiac hypoxia (17, 19). To date, however, evidence for a causal implication of CEACAM1 in angiogenesis in vivo was lacking. In the present study, we report on 2 different genetic mouse models in which the angiogenic action of CEACAM1 has been investigated: in CEACAM1endo+ mice, the expression of CEACAM1-L was targeted to endothelia via the Tie2 promoter, and in Ceacam1-/- mice, the Ceacam1 gene was inactivated by targeted disruption (29). In addition, endothelial cells were transfected with cDNAs coding for WT CEACAM1-L and for CEACAM1-L mutants harboring amino acid substitutions in the cytoplasmic domain. In these experimental systems, we provide conclusive evidence that CEACAM1 is involved in angiogenesis ...
PMID: Gut. 2013 Apr 18. Epub 2013 Apr 18. PMID: 23598352. Abstract Title: Western diet induces dysbiosis with increased E coli in CEABAC10 mice, alters host barrier function favouring AIEC colonisation. Abstract: OBJECTIVE: Western diet is a risk factor for Crohns disease (CD). Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) is abnormally expressed in CD patients. This allows adherent-invasive Escherichia coli (AIEC) to colonise the gut mucosa and leads to inflammation. We assessed the effects of a high fat/high sugar (HF/HS) Western diet on gut microbiota composition, barrier integrity and susceptibility to infection in transgenic CEABAC10 mice expressing human CEACAMs. DESIGN: Colonic microbiota composition and susceptibility of CEABAC10 mice to AIEC LF82 bacteria infection were determined in mice fed a conventional or HF/HS diet. Barrier function and inflammatory response were assessed by studying intestinal permeability, tight junction protein and mucin expression and ...
Soluble cell adhesion molecules (sCAMs) are a class of cell adhesion molecule (CAMs - cell surface binding proteins) that may represent important biomarkers for inflammatory processes involving activation or damage to cells such as platelets and the endothelium. They include soluble forms of the cell adhesion molecules ICAM-1, VCAM-1, E-selectin and P-selectin (distinguished as sICAM-1, sVCAM-1, sE-selectin and sP-selectin). The cellular expression of CAMs is difficult to assess clinically, but these soluble forms are present in the circulation and may serve as markers for CAMs. Research has focused on their role in cardiovascular (particularly atherosclerosis), connective tissue and neoplastic diseases, where blood plasma levels may be a marker of the disease severity or prognosis, and they may be useful in evaluating progress of some treatments. Many studies have postulated that increased production of cell adhesion molecules (CAMs) on the vascular endothelium (blood vessel lining) plays a ...

Cell and matrix adhesion of lymphocytes participates in homing, migration and accumulation of these cells in inflamed tissues as well as in the generation of immune and inflammatory responses. In inflamed joints of rheumatoid arthritis (RA) patients, lymphocytes accumulate in the synovial membrane and the synovial fluid. In the present study we have analyzed the expression of integrins and other adhesion molecules in synovial fluid lymphocytes (RA-SFL) and paired peripheral blood lymphocytes (RA-PBL) from 21 RA patients by immunofluorescence flow cytometry. We have also investigated the expression of these adhesion molecules on peripheral blood lymphocytes obtained from 13 sex- and age-matched healthy controls (CO-PBL). RA-SFL, which consisted mostly of T cells, showed higher expression of the integrin subunits beta 1 (CD29), VLA-1 alpha, -3 alpha, -4 alpha, -5 alpha and -6 alpha when compared to RA-PBL. In turn, RA-PBL showed lower expression of these molecules than CO-PBL. The expression of the

Epithelial cell adhesion molecule (EpCAM) is a transmembrane glycoprotein mediating Ca2+-independent homotypic cell-cell adhesion in epithelia. EpCAM is also involved in cell signaling, migration, proliferation, and differentiation. Additionally, EpCAM has oncogenic potential via its capacity to upregulate c-myc, e-fabp, and cyclins A & E. Since EpCAM is expressed exclusively in epithelia and epithelial-derived neoplasms, EpCAM can be used as diagnostic marker for various cancers. It appears to play a role in tumorigenesis and metastasis of carcinomas, so it can also act as a potential prognostic marker and as a potential target for immunotherapeutic strategies. First discovered in 1979, EpCAM was initially described as a dominant surface antigen on human colon carcinoma. Because of its prevalence on many carcinomas, it has been discovered many different times. EpCAM therefore has many aliases the most notable of which include TACSTD1 (tumor-associated calcium signal transducer 1), CD326 ...
Down Syndrome Cell Adhesion Molecules (dscam and dscaml1) are essential regulators of neural circuit assembly, but their roles in vertebrate neural circuit function are still mostly unexplored. We investigated the functional consequences of dscaml1 deficiency in the larval zebrafish (sexually undifferentiated) oculomotor system, where behavior, circuit function, and neuronal activity can be precisely quantified. Genetic perturbation of dscaml1 resulted in deficits in retinal patterning and light adaptation, consistent with its known roles in mammals. Oculomotor analyses revealed specific deficits related to the dscaml1 mutation, including severe fatigue during gaze stabilization, reduced saccade amplitude and velocity in the light, greater disconjugacy, and impaired fixation. Two-photon calcium imaging of abducens neurons in control and dscaml1 mutant animals confirmed deficits in saccade-command signals (indicative of an impairment in the saccadic premotor pathway), while abducens activation by ...

Human being epithelial cell adhesion molecule (HEPCAM) is a tumor-associated antigen frequently expressed in carcinomas, which promotes proliferation after controlled intramembrane proteolysis. which can be connected with mutations from the gene (9). Although Lei (8) reported a particular amount of embryonic lethality, the nice known reasons for these obvious discrepancies in phenotypes stay unknown. Furthermore, molecular systems in charge of the noticed Bay 11-7821 congenital tufting enteropathy phenotypes had been deviating. Guerra (7) suggested a job for adherens junctions having a mislocalization of E-cadherin and -catenin in the developing intestine (7), whereas Lei (8) excluded the participation of E-cadherin and -catenin, which were located properly, and a function was stated by them for mEpcam in the recruitment Bay 11-7821 of claudins to tight junctions. A job for Epcam in the forming of practical adherens junctions via E-cadherin was further referred to during epiboly Rabbit ...

In brain, signaling mediated by cell adhesion molecules defines the identity and functional properties of synapses. The specificity of presynaptic and postsynaptic interactions that is presumably mediated by cell adhesion molecules suggests that there exists a logic that could explain neuronal connectivity at the molecular level. Despite its importance, however, the nature of such logic is poorly understood, and even basic parameters, such as the number, identity, and single-cell expression profiles of candidate synaptic cell adhesion molecules, are not known. Here, we devised a comprehensive list of genes involved in cell adhesion, and used single-cell RNA sequencing (RNAseq) to analyze their expression in electrophysiologically defined interneurons and projection neurons. We compared the cell type-specific expression of these genes with that of genes involved in transmembrane ion conductances (i.e., channels), exocytosis, and rho/rac signaling, which regulates the actin cytoskeleton. Using these data,
|jats:p| The junctional adhesion molecules (JAMs) have been recently described as interendothelial junctional molecules and as integrin ligands. Here we show that JAM-B and JAM-C undergo heterophilic interaction in cell-cell contacts and that JAM-C is recruited and stabilized in junctional complexes by JAM-B. In addition, soluble JAM-B dissociates soluble JAM-C homodimers to form JAM-B/JAM-C heterodimers. This suggests that the affinity of JAM-C monomers to form dimers is higher for JAM-B than for JAM-C. Using antibodies against JAM-C, the formation of JAM-B/JAM-C heterodimers can be abolished. This liberates JAM-C from its vascular binding partner JAM-B and makes it available on the apical side of vessels for interaction with its leukocyte counterreceptor α|jats:sub|M|/jats:sub|β|jats:sub|2|/jats:sub| integrin.

TY - JOUR. T1 - Role of cellular adhesion molecules in HIV type 1 infection and their impact on virus neutralization. AU - Hioe, C. E.. AU - Bastiani, L.. AU - Hildreth, James. AU - Zolla-Pazner, S.. PY - 1998. Y1 - 1998. N2 - While CD4 and several chemokine receptors are the principal receptors for human immunodeficiency virus type 1 (HIV-1) viruses, other cell membrane proteins also play a role in HIV-1 infection. A large array of host cell- derived membrane proteins, including adhesion molecules, are incorporated into the envelope of HIV-1 virions, and the profile of host cell proteins acquired by the virus depends on the cells used to propagate the virus. The major leukocyte adhesion molecules, such as leukocyte-function associated antigen-1 (LFA-1), intercellular adhesion molecule-1 (ICAM-1), and CD44, retain their biological functions when expressed on the virion surface, and have been shown to increase virus-cell interaction, enhance virus infectivity, and extend the host cell range of ...

BACKGROUND:Colorectal Cancer (CRC) is one of the most frequently diagnosed neoplasms and also one of the main death causes. Cell adhesion molecules are taking part in specific junctions, contributing to tissue integrality. Lower expression of the cadherins may be correlated with poorer differentiation of the CRC, and its more aggressive phenotype. The aim of the study is to designate the cadherin genes potentially useful for the diagnostics, prognostics, and the treatment of CRC. MATERIAL AND METHODS:Specimens were collected from 28 persons (14 female and 14 male), who were operated for CRC. The molecular analysis was performed using oligonucleotide microarrays, mRNA used was collected from adenocarcinoma, and macroscopically healthy tissue. The results were validated using qRT-PCR technique. RESULTS:Agglomerative hierarchical clustering of normalized mRNA levels has shown 4 groups with statistically different gene expression. The control group was divided into 2 groups, the one was appropriate control

Cell adhesion molecules play an important role in the development of several chronic fibroproliferative diseases such as glomerulosclerosis, cirrhosis, pulmonary fibrosis, and atherosclerosis.7 The infiltration of monocytes and T lymphocytes, which initiates the atherosclerotic process, is mediated by adhesion receptors. Once they have entered the vascular wall, leucocytes release a variety of cytokines and other bioactive molecules. This results in the proliferation and migration of smooth muscle cells and subsequently promotes the deposition of excess connective tissue.8 These actions are primarily regulated by β1 integrins, although VCAM-1 is also expressed strongly on the surface of activated smooth muscle cells and may help to retain leucocytes within atherosclerotic vessels.9 The αvβ3 integrin has been demonstrated in atherosclerotic plaques10 and may be a therapeutic target that, if blocked, could prevent the formation of new vessels-reducing plaque growth and the migration of smooth ...
Normal and malignant cells release a variety of different vesicles into their extracellular environment. The most prominent vesicles are the microvesicles (MVs, 100-1 000 nm in diameter), which are shed of the plasma membrane, and the exosomes (70-120 nm in diameter), derivates of the endosomal system. MVs have been associated with intercellular communication processes and transport numerous proteins, lipids and RNAs. As essential component of immune-escape mechanisms tumor-derived MVs suppress immune responses. Additionally, tumor-derived MVs have been found to promote metastasis, tumor-stroma interactions and angiogenesis. Since members of the carcinoembryonic antigen related cell adhesion molecule (CEACAM)-family have been associated with similar processes, we studied the distribution and function of CEACAMs in MV fractions of different human epithelial tumor cells and of human and murine endothelial cells. Here we demonstrate that in association to their cell surface phenotype, MVs released ...

AMIGO-1, which mediates homophilic cell adhesion underlying neurite outgrowth and fasciculation during development, has recently been shown to be an auxiliary subunit of adult brain Kv2.1-containing Kv channels. We show that AMIGO-1 is extensively colocalized with both Kv2.1 and its paralog Kv2.2 in ...
The CD56 antigen is a 140 kDa isoform of the Neural Cell Adhesion Molecule (N-CAM). Post-translational modifications to the polypeptide include N- and O- glycosylations, acylation, sulphation and phosphorylation. The different N-CAM isoforms have molecular weights ranging from 135 to 220 kDa. The CD56 antigen is moderately expressed on a subpopulation of peripheral blood large granular lymphocytes and on all cells with NK activity. It is also expressed by subsets of T lymphocytes. CD56 antibodies do not react with granulocytes, monocytes or B cells.
The crystal structure of a soluble form of the T lymphocyte antigen CD2 provides the first complete view of the extracellular region of a cell adhesion molecule. The topology of the molecule, which comprises two immunoglobulin-like domains, is the same as that of the first two domains of CD4 but the relative domain orientation is altered by a fairly flexible linker region. The putative ligand-binding beta-sheet forms a flat surface towards the top of the molecule. Crystal contacts between these surfaces suggest a plausible model for the adhesive interaction.

Cell adhesion molecules are (glyco)proteins expressed on the cell surface and play a critical role in a wide array of biologic processes that include hemostasis, the immune response, inflammation, embryogenesis, and development of neuronal tissue. There are four main groups: the integrin family, the immunoglobulin superfamily, selectins, and cadherins. Membrane proteins that mediate immune cell-cell interactions fall into different categories, namely those involved in antigen recognition, costimulation and cellular adhesion. Furthermore cell-cell adhesions are important for brain morphology and highly coordinated brain functions such as memory and learning. During early development of the nervous system, neurons elongate their axons towards their targets and establish and maintain synapses through formation of cell-cell adhesions. Cell-cell adhesions also underpin axon-axon contacts and link neurons with supporting schwann cells and oligodendrocytes ...

The cell-cell adhesion molecule 1 (C-CAM1) plays an important role as a tumor suppressor for prostate cancer. Decreased expression of C-CAM1 was detected in prostate, breast, and colon carcinoma. Reexpression of C-CAM1 in prostate and breast cancer cell lines was able to suppress tumorigenicity in vivo. These observations suggest that C-CAM1 may be used as a marker for cancer detection or diagnosis. To generate monoclonal antibodies specific to C-CAM1, we have overexpressed full-length human C-CAM1 in Sf9 cells using a baculovirus expression system. The protein was purified 104-fold using nickel affinity chromatography. About 0.4 mg purified C-CAM1 was obtained from 200 mg of infected cells. When the purified protein was digested with peptidyl-N-glycosidase, the apparent mobility of the protein on SDS-PAGE changed from 90 to 58 kDa, which is close to the molecular weight predicted from the cloned cDNA sequence. This observation suggests that C-CAM1 was glycosylated on asparagine residues when expressed
Initially discovered as a dominant antigen on colon carcinomas, the epithelial cell adhesion molecule (EpCAM) was considered a mere cell adhesion molecule and reliable surface-binding site for therapeutic antibodies. Recent findings can better explain the relevance of EpCAMs high-level expression on human cancers and cancer propagating cells, and its negative prognostic potential for survival of patients with certain cancers. EpCAM has oncogenic potential and is activated by release of its intracellular domain, which can signal into the cell nucleus by engagement of elements of the wnt pathway.
The members of the IgLON superfamily of cell adhesion molecules facilitate fundamental cellular communication during brain development, maintain functional brain circuitry, and are associated with several neuropsychiatric disorders. Usage of alternative promoter-specific 1a and 1b mRNA isoforms in Lsamp, Opcml, Ntm and the single promoter of Negr1 in the mouse and human brain has been previously described. To determine the precise spatiotemporal expression dynamics of Lsamp, Opcml, Ntm isoforms and Negr1, in the developing brain, we generated isoform-specific RNA probes and carried out in situ hybridization in the developing (embryonic, E10.5, 13.5, 17; post natal, P0) and adult mouse brains. We show that promoter-specific expression of IgLONs is established early during pallial development (at E10.5), where it remains throughout its differentiation through adulthood. In the diencephalon, midbrain and hindbrain, strong expression patterns are initiated a few days later and begin fading after birth,
The mechanism by which low affinity adhesion molecules function to produce stable cell-cell adhesion is unknown. In solution, the interaction of human CD2 with its ligand CD58 is of low affinity (500 mM-1) and the interaction of rat CD2 with its ligand CD48 is of still lower affinity (40 mM-1). At the molecular level, however, the two systems are likely to be topologically identical. Fluorescently labeled glycosylphosphatidylinositol-anchored CD48 and CD58 were prepared and incorporated into supported phospholipid bilayers, in which the ligands were capable of free lateral diffusion. Quantitative fluorescence imaging was used to study the binding of cell surface human and rat CD2 molecules to the fluorescent ligands in contact areas between Jurkat cells and the bilayers. These studies provide two major conclusions. First, CD2/ligand interactions cooperate to align membranes with nanometer precision leading to a physiologically effective two-dimensional affinity. This process does not require the intact

TY - JOUR. T1 - Structural model of the catalytic domain of an enzyme with cell adhesion activity: human vascular adhesion protein-1 (HVAP-1) D4 domain is an amine oxidase. AU - Salminen, Tiina. AU - Smith, DJ. AU - Jalkanen, S. AU - Johnson, Mark S. PY - 1998. Y1 - 1998. N2 - Human vascular adhesion protein-1 (HVAP-1) is a multifunctional protein having at least two different cellular roles, functioning both as a lymphocyte-endothelial cell adhesion protein and as an enzyme with monoamine oxidase activity. HVAP-1 is a 180 kDa homodimeric glycoprotein consisting of a membrane-spanning domain and three predicted extracellular copper-containing amine oxidase domains. In HVAP-1 the extracellular domains are composed of a large domain DJ, containing the active site and forming the interface of the dimer, while the smaller D2 and D3 domains surround the D4 dimer near the entrance to the active site. The structural model of the catalytic D4 domain of HVAP-1 reveals that all components necessary for ...

The cytoplasmic tails enable interactions with other intracellular
Human vascular adhesion protein-1 (HVAP-1) is a multifunctional protein having at least two different cellular roles, functioning both as a lymphocyte-endothelial cell adhesion protein and as an enzyme with monoamine oxidase activity. HVAP-1 is a 180 kDa homodimeric glycoprotein consisting of a membrane-spanning domain and three predicted extracellular copper-containing amine oxidase domains. In HVAP-1 the extracellular domains are composed of a large domain DJ, containing the active site and forming the interface of the dimer, while the smaller D2 and D3 domains surround the D4 dimer near the entrance to the active site. The structural model of the catalytic D4 domain of HVAP-1 reveals that all components necessary for enzymatic monoamine oxidase activity are indeed present within the HVAP-1 and pinpoints residues that may be key to substrate entry through a channel to the active site and residues likely to be involved in substrate specificity as well as structural features critical to dimer ...
Background T cell exhaustion has recently been proposed as an alternative mechanism to prevent memory development and tissue damage arising during ischemia-reperfusion injury (IRI) in murine orthotopic liver transplantation (OLT), with carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) identified as a key ligand for TIM-3-mediated negative immune regulation in the liver. In our cohort of human OLT patients, IRI+ recipients had a 12-fold higher ratio of TIM-1+:TIM-3+ CD4+ T cells at 3 months post-transplant than IRI-. Aim We sought to investigate donor and recipient contributions to CEACAM1 expression in human OLT-IRI. Methods We compared the cellular expression of CEACAM1 biopsies obtained from the donor organ pre- and post-reperfusion with the recipient's portal blood. Additionally, we evaluated CEACAM1 expression of 3rd party healthy donor monocytes co-cultured for 4 days with recipient portal blood obtained both pre- and post-reperfusion through the donor organ. Results ...
Junctional adhesion molecule-C (JAM-C) is an adhesion molecule involved in transendothelial migration of leukocytes. In this study, we examined JAM-C expression in the synovium and investigated the role of this molecule in two experimental mouse models of arthritis. JAM-C expression was investigated by reverse transcriptase-polymerase chain reaction and immunohistochemistry. The effects of a monoclonal anti-JAM-C antibody were assessed in antigen-induced arthritis (AIA) and K/BxN serum transfer-induced arthritis. JAM-C was expressed by synovial fibroblasts in the lining layer and associated with vessels in the sublining layer in human and mouse arthritic synovial tissue. In human tissue, JAM-C expression was increased in rheumatoid arthritis (RA) as compared to osteoarthritis synovial samples (12.7 ± 1.3 arbitrary units in RA versus 3.3 ± 1.1 in OA; p | 0.05). Treatment of mice with a monoclonal anti-JAM-C antibody decreased the severity of AIA. Neutrophil infiltration into inflamed joints was

Inflammation is related to many diseases, such as atherosclerosis, rheumatoid arthritis and metabolic diseases. Vascular adhesion protein-1 (VAP-1) is an endothelial adhesion molecule involved in leukocyte trafficking cascades from blood circulation to the sites of inflammation. In normal condition, VAP-1 is stored in intracellular granules. During inflammation it is rapidly translocated from the intracellular storage granules to the endothelial cell surface. Siglec-9 is a leukocyte ligand of VAP-1 and Siglec-9 motif containing peptide can be used as a positron emission tomography (PET) tracer for in vivo imaging of inflammation-related diseases ...
TY - JOUR. T1 - ENDOTHELIAL CELL ADHESION MOLECULES IN PSORIASIS. AU - Lee, May‐Lian ‐L. AU - To, Shing Shun Tony. AU - Nicholson, Ellen. AU - Schrieber, Leslie. PY - 1994/1/1. Y1 - 1994/1/1. N2 - Skin biopsies from patients with psoriasis and normal controls were examined for the expression of cell adhesion molecules including intercellular adhesion molecule‐1 (ICAM‐1) endothelial leukocyte adhesion molecule‐1 (ELAM‐1), HECA‐452 and 4D10, using an immunoperoxidase techique. This study demonstrates that psoriatic skin exhibits a wide variety of markers of endothelial cell activation which are either induced or increased expression (ICAM‐1, ELAM‐1 & 4D10). Moreover, ICAM‐1 & HECA‐452 are also on leukocytes. These antigens may facilitate the adhesion of inflammatory cells to endothelium and antigen‐presenting cells in psoriatic skin. Thus, they may play a role in faciliating the infiltration of leukocytes into psoriatic skin.. AB - Skin biopsies from patients with psoriasis ...
In arthropods like Drosophila, Down syndrome cell adhesion molecules (Dscam1) exhibit enormous molecular diversity. A single Dscam1 gene encodes a large superfamily of neuronal cell recognition proteins that control neuronal outgrowth and anatomy. A comparable function is exhibited by the vertebrates DSCAMs of which only few isoforms exist. However, it is largely unknown, if and how this function of Dscams affects neuronal function and the control of behavior by the nervous system. In this thesis, I employed an arsenal of genetic techniques to perturb the expression level of Dscam1 isoforms in directionally selective Lobula Plate Tangential Cells (LPTCs). LPTCs of the Vertical (VS) and the Horizontal System (HS) were chosen as a model system because of their well-documented anatomy, role in information processing and behavior. Though, only little is known about the developmental mechanisms and molecular factors controlling the morphogenesis and wiring of these cells. The central aim of my study ...
Cell Biol Int. 2021 Mar 24. doi: 10.1002/cbin.11598. Online ahead of print.. ABSTRACT. Overexpression of breast cancer resistance protein (BCRP) plays a crucial role in the acquired multidrug resistance (MDR) in breast cancer. The elucidation of molecular events that confer BCRP-mediated MDR is of major therapeutic importance in breast cancer. Epithelial cell adhesion molecule (EpCAM) has been implicated in tumor progression and drug resistance in various types of cancers, including breast cancer. However, the role of EpCAM in BCRP-mediated MDR in breast cancer remains unknown. In the present study, we revealed that EpCAM expression was upregulated in BCRP-overexpressing breast cancer MCF-7/MX cells, and EpCAM knockdown using siRNA reduced BCRP expression and increased the sensitivity of MCF-7/MX cells to mitoxantrone (MX). Epithelial-mesenchymal transition (EMT) promoted BCRP-mediated MDR in breast cancer cells, and EpCAM knockdown partially suppressed EMT progression in MCF-7/MX cells. In ...
Purpose Among cell adhesion molecules, serum degrees of intercellular adhesion molecule-1 and E-selectin are regarded as correlated with the metastatic potential of gastric cancer. in gastric cancers tissue and cultured gastric cancers cells were elevated, however, E-selectin in gastric cancers tissue and cells werent elevated. Among 157 gastric malignancy patients, 79 patients (50%) were intercellular adhesion molecule-1 positive and experienced larger tumor FCRL5 size, an increased depth of tumor invasion, lymph node metastasis and perineural invasion. The intercellular adhesion molecule-1 positive group showed a higher incidence of tumor recurrence (40.5%), and a poorer 3-12 months survival than the negative group (54.9 vs. 85.9%, respectively). Conclusions Intercellular adhesion molecule-1 is usually overexpressed in gastric malignancy tissues and cultured gastric malignancy cells, whereas E-selectin is not overexpressed. Increased expression of intercellular adhesion molecule-1 in gastric ...
CEACAM6 (carcinoembryonic antigen related cell adhesion molecule 6), Authors: Dessen P. Published in: Atlas Genet Cytogenet Oncol Haematol.
I have examined the distribution of neural cell adhesion molecule (N-CAM) in cultured C2 myogenic cells and other cell lines to determine if N-CAM accumulates at sites of cell-cell contact. C2 cells growing in log phase display large clusters of neural cell adhesion molecule where they contact each other. These clusters are remarkably stable, do not form at cell-substrate contacts, and appear not to be enriched in a number of other cytoskeletal, membrane, or extracellular proteins. Thus, N-CAM clusters form preferentially in response to cell-cell contact and are specifically enriched in N-CAM. As C2 cultures mature and differentiate, clusters persist at contacts between aligning myoblasts and between myotubes, consistent with a role in myogenesis. N-CAM is also enriched at cell-cell contacts in cultures of PC12, NRK, and CHO cells. These cells have significant amounts of N-CAM as detected on immunoblots. Clusters are not seen in L929 cells, which do not have detectable amounts of N-CAM. ...

PY - 1989. Y1 - 1989. N2 - A 90-kD lymphocyte surface glycoprotein, defined by monoclonal antibodies of the Hermes series, is involved in lymphocyte recognition of high endothelial venules (HEV). Lymphocyte gp90(Hermes) binds in a saturable, reversible fashion to the mucosal vascular addressin (MAd), a tissue-specific endothelial cell adhesion molecule for lymphocytes. We and others have recently shown that the Hermes antigen is identical to or includes CD44 (In[Lu]-related p80), human Pgp-1, and extracellular matrix receptor III-molecules reportedly expressed on diverse cell types. Here, we examine the relationship between lymphoid and non-lymphoid Hermes antigens using serologic, biochemical, and, most importantly, functional assays. Consistent with studies using mAbs to CD44 or Pgp-1, mAbs ...
Levels of the neural cell adhesion molecule N-CAM in muscle are regulated in parallel with the susceptibility of muscle to innervation: N-CAM is abundant on the surface of early embryonic myotubes, declines in level as development proceeds, reappears when adult muscles are denervated or paralyzed, and is lost after reinnervation (Covault, J., and J. R. Sanes, 1985, Proc. Natl. Acad. Sci. USA, 82:4544-4548). Here we used immunocytochemical methods to compare this pattern of expression with those of several other molecules known to be involved in cellular adhesion. Laminin, fibronectin, and a basal lamina-associated heparan sulfate proteoglycan accumulate on embryonic myotubes after synapse formation, and their levels change little after denervation. L1, J1, nerve growth factor-inducible large external protein, uvomorulin, and a carbohydrate epitope (L2/HNK-1) shared by several adhesion molecules are undetectable on the surface of embryonic, perinatal, adult, or denervated adult muscle fibers. ...

TY - JOUR. T1 - Innate signaling by the C-type lectin DC-SIGN dictates immune responses. AU - den Dunnen, J.. AU - Gringhuis, S.I.. AU - Geijtenbeek, T.B.H.. PY - 2009. Y1 - 2009. N2 - Effective immune responses depend on the recognition of pathogens by dendritic cells (DCs) through pattern recognition receptors (PRRs). These receptors induce specific signaling pathways that lead to the induction of immune responses against the pathogens. It is becoming evident that C-type lectins are also important PRRs. In particular, the C-type lectin DC-SIGN has emerged as a key player in the induction of immune responses against numerous pathogens by modulating TLR-induced activation. Recent reports have begun to elucidate the molecular mechanisms underlying these immune responses. Upon pathogen binding, DC-SIGN induces an intracellular signaling pathway with a central role for the serine/threonine kinase Raf-1. For several pathogens that interact with DC-SIGN, including Mycobacterium tuberculosis and ...
A new study published in Biological Psychiatry suggests that autism is associated with reductions in the level of cellular adhesion molecules in the blood, where they play a role in immune function.. Cell adhesion molecules are the glue that binds cells together in the body. Deficits in adhesion molecules would be expected to compromise processes at the interfaces between cells, influencing tissue integrity and cell-to-cell signaling. In the brain, deficits in adhesion molecules could compromise brain development and communication between nerve cells.. Over the years, deficits in neural cell adhesion molecules have been implicated in schizophrenia and other psychiatric disorders. One adhesion molecule, neurexin, is strongly implicated in the heritable risk for autism.. Cell adhesion molecules also play a crucial role in regulating immune cell access to the central nervous system. Prior research provided evidence of immune system dysfunction in individuals diagnosed with autism spectrum disorder ...
BACKGROUND The cell adhesion between vascular endothelial cells and leukocytes is an important process for the immuno-inflammatory changes. To clarify the basic features of inflammatory bowel disease (IBD), studies of in situ localization of the cell adhesion molecules are required. EXPERIMENTAL DESIGN We analyzed the immunohistochemical localization of the adhesion molecules (ICAM-1, LFA-1, Mac-1, VCAM-1, VLA-4, P- and E-selectins) in IBD, stressing phenotypical changes of endothelial cells. RESULTS In the normal mucosa, ICAM-1 was expressed in capillaries and venules, LFA-1 in some lymphocytes and VLA-4 in most lymphocytes. VCAM-1 was expressed sporadically in venules and constantly in follicular dendritic cells (FDC) in lymphoid follicles. Both E- and P-selectins were sporadically expressed in venules. In actively inflamed mucosa in IBD, a marked increase of all these antigens was observed; ICAM-1+ inflammatory infiltrates (lymphocytes, plasma cells, and macrophages) and ICAM-1+ venules increased
Cadherin cell adhesion molecules play crucial tasks in vertebrate development including the development of the retina. of embryonic zebrafish resulted in similar eye problems. Our results suggest that protocadherin-17 plays an important part in the normal formation of the zebrafish retina. ((MO (MOs sequences showed no significant similarities to any sequences (using BLAST) other than zebrafish (GenBank accession quantity: XM 684743). MOs were microinjected into one- to four-cell stage embryos (1.5-3 ng/embryo) in Daneau buffer (58 mM NaCl, 0.7 mM KCl, 0.4 mM MgSO4, 0.6 mM Ca(NO3)2, 5.0 mM HEPES pH 7.6). The zebrafish coding region was amplified with primers comprising EcoRI (5) and XbaI (3) restriction sites and cloned 1st into pCR2.1-TOPO vector (Existence Systems, Carlsbad, CA), followed by cloning into pCS2+MT vector (Dr. Pamela Raymond, the University of Michigan). The pCS2+MT/pcdh17 was verified by restriction digestion and sequencing (Macrogen, Rockville, MD). Capped mRNA was synthesized ...
Cell adhesion molecule which is required for leukocyte transendothelial migration (TEM) under most inflammatory conditions. Tyr-660 plays a critical role in TEM and is required for efficient trafficking of PECAM1 to and from the lateral border recycling compartment (LBRC) and is also essential for the LBRC membrane to be targeted around migrating leukocytes. Prevents phagocyte ingestion of closely apposed viable cells by transmitting detachment signals, and changes function on apoptosis, promoting tethering of dying cells to phagocytes (the encounter of a viable cell with a phagocyte via the homophilic interaction of PECAM1 on both cell surfaces leads to the viable cells active repulsion from the phagocyte. During apoptosis, the inside-out signaling of PECAM1 is somehow disabled so that the apoptotic cell does not actively reject the phagocyte anymore. The lack of this repulsion signal together with the interaction of the eat-me signals and their respective receptors causes the attachment of the

N1 - Copyright: Copyright 2007 Elsevier B.V., All rights reserved.. PY - 1990. Y1 - 1990. N2 - It has recently become clear that both extracellular matrix (ECM) glycoproteins and various cell adhesion molecules (CAMs) can promote neurite outgrowth from primary neurons, though little is known of the intracellular mechanisms through which these signals are transduced. We have previously obtained evidence that protein kinase C function is an important part of the neuronal response to laminin (Bixby, J. L. 1989. Neuron. 3:287-297). Because such CAMs as L1 (Lagenauer, C., and V. Lemmon. 1987. Proc. Natl. Acad. Sci. USA. 84:7753-7757) and N-cadherin (Bixby, J. L. and R. Zhang. 1990. J. Cell Biol. 110:1253-1260) can be purified and used as substrates to promote neurite growth, we have now tested whether the response to CAMs is similarly dependent ...

AU - Gavert, Nancy. AU - Sakurai, Takeshi. AU - Ben-Zeev, Avri. PY - 2005/12/15. Y1 - 2005/12/15. N2 - Nr-CAM, a cell-cell adhesion molecule of the immunoglobulin-like cell adhesion molecule family, known for its function in neuronal outgrowth and guidance, was recently identified as a target gene of β-catenin signaling in human melanoma and colon carcinoma cells and tissue. Retrovirally mediated transduction of Nr-CAM into fibroblasts induces cell motility and tumorigenesis. We investigated the mechanisms by which Nr-CAM can confer properties related to tumor cell behavior and found that Nr-CAM expression in NIH3T3 cells protects cells from apoptosis in the absence of serum by constitutively activating the extracellular signal-regulated kinase and AKT signaling pathways. We detected a ...
To evaluate the expression and test the clinical significance of the epithelial cellular adhesion molecule (Ep-CAM) in esophageal squamous cell carcinoma (SCC) to check the suitability of esophageal SCC patients for Ep-CAM directed targeted therapies. The Ep-CAM expression was immunohistochemically investigated in 70 primary esophageal SCCs using the monoclonal antibody Ber-EP4. For the interpretation of the staining results, we used a standardized scoring system ranging from 0 to 3+. The survival analysis was calculated from 53 patients without distant metastasis, with R0 resection and at least 2 months of clinical follow-up. Ep-CAM neo-expression was observed in 79% of the tumors with three expression levels, 1+ (26%), 2+ (11%) and 3+ (41%). Heterogeneous expression was observed at all expression levels. Interestingly, tumors with 3+ Ep-CAM expression conferred a significantly decreased median relapse-free survival period (log rank, p = 0.0001) and median overall survival (log rank, p = 0.0003).
TY - JOUR. T1 - The role of endothelial cell adhesion molecules in the development of atherosclerosis. AU - Berman, Joan W.. AU - Calderon, Tina M.. PY - 1992/1/1. Y1 - 1992/1/1. N2 - The vascular endothelium serves as a dynamic interface between circulating blood elements and the interstitial tissues. As such, it communicates to cells within the vessel wall as well as to the surrounding tissue, sensing its environment and responding accordingly. The vasculature must maintain a delicate balance when initiating a functional response by producing both proinflammatory and antiinflammatory mediators, vasoconstrictors and vasodilators, growth stimulators and inhibitors, and prothrombogenic and antithrombogenic factors. Any response to injurious agents could lead to pathology. Confounding this complex interplay is the fact that the very response to injury that may have developed to undo the damage may itself be even more deleterious. One response to injury by the endothelium is the new or increased ...
ABSTRACT: INTRODUCTION: The adhesion protein junctional adhesion molecule-A (JAM-A) regulates epithelial cell morphology and migration, and its over-expression has recently been linked with increased risk of metastasis in breast cancer patients. As cell migration is an early requirement for tumor metastasis, we sought to identify the JAM-A signalling events regulating migration in breast cancer cells. METHODS: MCF7 breast cancer cells (which express high endogenous levels of JAM-A) and primary cultures from breast cancer patients were used for this study. JAM-A was knocked down in MCF7 cells using siRNA to determine the consequences for cell adhesion, cell migration and the protein expression of various integrin subunits. As we had previously demonstrated a link between the expression of JAM-A and β1-integrin, we examined activation of the β1-integrin regulator Rap1 GTPase in response to JAM-A knockdown or functional antagonism. To test whether JAM-A, Rap1 and β1-integrin lie in a linear pathway, we
Cells attach to proteoglycans and glycoproteins on the surface of other cells as well as in the extracellular matrix (ECM) substratum via adhesion molecules to define tissue shape, structure, and function. Making and breaking cellular contacts with other cells and the ECM play critical roles in normal processes such as cell growth, division, differentiation, and migration. Cardiovascular and central nervous system disorders and pathophysiological processes such as fibrosis and inflammation require ECM remodeling. Remodeling involves expression of different cell adhesion molecules, altering cellular processes such as migration and polarity. Key ECM proteins include fibronectin, laminin, and collagens as well as metalloproteinases that remodel the ECM. Important cell adhesion genes include integrins, selectins, celladhesion molecule family members (ICAM, ECAM, NCAM, PECAM, and VCAM), and the catenins which link cell adhesion molecules and the cytoskeleton. Analysis of these essential genes may ...

AU - Kenney, John S.. AU - Issekutz, Andrew C.. PY - 1998/10/16. Y1 - 1998/10/16. N2 - We investigated the effect of TNFα, IL-1α and IFNγ on two neuroblastoma (NB) cell lines (SK-N-SH and SK-N-MC). These lines responded differentially to IL-1α, TNFα and IFNγ for MCP-1 and IL-8 production and expression of the ICAM-1 and VCAM-1 adhesion molecules. None of the cytokines induced MCP-1 or 1L-8 on SK-N-MC cells. Both chemokines were produced in response to IL-1α by SK-N-SH cells, while TNFα induced mainly MCP-1 production. Addition of IFNγ decreased IL-8, but not MCP-1 production. These responses correlated with monocyte and neutrophil chemotactic activity in NB culture supernatants. This activity was neutralized by antibodies to IL-8 and MCP-1. The expression of ICAM-1 on SK-N-MC was up-regulated ...

We demonstrate that α6β4 integrin mediates pancreatic epithelial cell adhesion to Netrin-1, whereas recruitment of α6β4 and α3β1 regulate the migration of CK19+/PDX1+ putative pancreatic progenitors on ...
The diffusion characteristics of BoNT have been well studied in humans7-10 and animals11,12 using a variety of techniques, including compound muscle action potentials (CMAPs) and motor-evoked potentials,7 histological determination of glycogen-depleted muscles,13 acetylcholine esterase staining,14 muscle fiber diameter variability,15 and quantitative electromyography (EMG) measures of muscle activity.16. Evidence for diffusion comes from both animal and human studies. In a study using muscle biopsy to identify spread, Borodic et al.15 reported a diffusion gradient of BoNT/A over a distance of 30-45 mm from the point of injection into latissimus dorsi muscle of rabbits.14 The extent of denervation gradient or diffusion was dose dependent. Another study used neural cell adhesion molecule (N-CAM) staining to assess the diffusion of activity of equipotent doses of three BoNT/A formulations from the point of injection along the mouse hind limb. The results showed a similar time course of paralysis, ...
Chronic inflammation and reduced blood levels of omega-3 fatty acids (n − 3) are known characteristics of sickle cell disease (SCD).The anti-inflammatory properties of n − 3 fatty acids are well recognized.. Omega-3 treated (n = 24), hydroxyurea (HU) treated (n = 18), and n − 3 untreated (n = 21) homozygous SCD patients (HbSS) and healthy (HbAA) controls (n = 25) matched for age (5-16 years), gender and socioeconomic status were studied.

Cancer cell metastasis is one of the most critical steps in tumor development and is responsible for more than 80 of cancer related deaths. Among the molecules involved in promoting cancer metastasis, the role of the cell adhesion molecules, CD44 and CD146 are well known in promoting cancer cell motility and metastasis. Despite this knowledge, the molecular mechanism through which CD44 promotes tumor development and cell metastasis is still nascent. CD146 (MUC 18) was, first identified in highly metastatic melanomas. The absence of CD146 in normal melanocytes and its high expression in melanomas suggests its tumor promoting actions. Despite the association between CD146 expression and development of melanoma, its expression patterns and role in normal and metastatic breast tissues still remains controversial. This study aims to elucidate some of these discrepancies by presenting CD146 as a downstream target for CD44, in a way such that CD146 expression is related to CD44 and regulates the tumor ...

Periostin expression status was detected in CSC cells and 1,086 breast cancer specimens by Western blot and immunohistochemistry staining, with the CSC ratio determined by immunofluorescence double staining. The relationship between the periostin protein and clinico-pathological parameters and prognosis was subsequently determined. As a result, CSC cells are more likely to generate new tumors in mice and cell microspheres that are deficient in NOD/SCID compared to the control group. Periostin protein was expressed higher in CSC cells compared to the control cells and was found to be related to CSC chemotherapy resistance. Moreover, periostin expression was found to be related to the CSC ratio in 1,086 breast cancer specimens (P = 0.001). In total
