A subcomponent of complement C1, composed of six copies of three polypeptide chains (A, B, and C), each encoded by a separate gene (C1QA; C1QB; C1QC). This complex is arranged in nine subunits (six disulfide-linked dimers of A and B, and three disulfide-linked homodimers of C). C1q has binding sites for antibodies (the heavy chain of IMMUNOGLOBULIN G or IMMUNOGLOBULIN M). The interaction of C1q and immunoglobulin activates the two proenzymes COMPLEMENT C1R and COMPLEMENT C1S, thus initiating the cascade of COMPLEMENT ACTIVATION via the CLASSICAL COMPLEMENT PATHWAY.
An abundant pulmonary surfactant-associated protein that binds to a variety of lung pathogens, resulting in their opsinization. It also stimulates MACROPHAGES to undergo PHAGOCYTOSIS of microorganisms. Surfactant protein A contains a N-terminal collagen-like domain and a C-terminal lectin domain that are characteristic of members of the collectin family of proteins.
Molecules on the surface of some B-lymphocytes and macrophages, that recognize and combine with the C3b, C3d, C1q, and C4b components of complement.
A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.
Complement activation initiated by the binding of COMPLEMENT C1 to ANTIGEN-ANTIBODY COMPLEXES at the COMPLEMENT C1Q subunit. This leads to the sequential activation of COMPLEMENT C1R and COMPLEMENT C1S subunits. Activated C1s cleaves COMPLEMENT C4 and COMPLEMENT C2 forming the membrane-bound classical C3 CONVERTASE (C4B2A) and the subsequent C5 CONVERTASE (C4B2A3B) leading to cleavage of COMPLEMENT C5 and the assembly of COMPLEMENT MEMBRANE ATTACK COMPLEX.
A glycoprotein that is important in the activation of CLASSICAL COMPLEMENT PATHWAY. C4 is cleaved by the activated COMPLEMENT C1S into COMPLEMENT C4A and COMPLEMENT C4B.

The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia). Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies. They have also been suggested to act in several other roles including in secretion (e.g., of cytokines and neural growth factors), in immunological processing (e.g., antigen presentation), and in central nervous system development and remodeling.
Enzymes that activate one or more COMPLEMENT PROTEINS in the complement system leading to the formation of the COMPLEMENT MEMBRANE ATTACK COMPLEX, an important response in host defense. They are enzymes in the various COMPLEMENT ACTIVATION pathways.
The first complement component to act in the activation of CLASSICAL COMPLEMENT PATHWAY. It is a calcium-dependent trimolecular complex made up of three subcomponents: COMPLEMENT C1Q; COMPLEMENT C1R; and COMPLEMENT C1S at 1:2:2 ratios. When the intact C1 binds to at least two antibodies (involving C1q), C1r and C1s are sequentially activated, leading to subsequent steps in the cascade of COMPLEMENT ACTIVATION.
A 80-kDa subcomponent of complement C1, existing as a SERINE PROTEASE proenzyme in the intact complement C1 complex. When COMPLEMENT C1Q is bound to antibodies, the changed tertiary structure causes autolytic activation of complement C1r which is cleaved into two chains, A (heavy) and B (light, the serine protease), connected by disulfide bonds. The activated C1r serine protease, in turn, activates COMPLEMENT C1S proenzyme by cleaving the Arg426-Ile427 bond. No fragment is released when either C1r or C1s is cleaved.
Hospital department which administers and provides pathology services.
A 77-kDa subcomponent of complement C1, encoded by gene C1S, is a SERINE PROTEASE existing as a proenzyme (homodimer) in the intact complement C1 complex. Upon the binding of COMPLEMENT C1Q to antibodies, the activated COMPLEMENT C1R cleaves C1s into two chains, A (heavy) and B (light, the serine protease), linked by disulfide bonds yielding the active C1s. The activated C1s, in turn, cleaves COMPLEMENT C2 and COMPLEMENT C4 to form C4b2a (CLASSICAL C3 CONVERTASE).

C1qRP is a heavily O-glycosylated cell surface protein involved in the regulation of phagocytic activity. (1/737)

C1q, mannose-binding lectin (MBL), and pulmonary surfactant protein A (SPA) interact with human monocytes and macrophages, resulting in the enhancement of phagocytosis of suboptimally opsonized targets. mAbs that recognize a cell surface molecule of 126,000 Mr, designated C1qRP, have been shown to inhibit C1q- and MBL-mediated enhancement of phagocytosis. Similar inhibition of the SPA-mediated enhancement of phagocytosis by these mAbs now suggests that C1qRP is a common component of a receptor for these macromolecules. Ligation of human monocytes with immobilized R3, a IgM mAb recognizing C1qRP, also triggers enhanced phagocytic capacity of these cells in the absence of ligand, verifying the direct involvement of this polypeptide in the regulation of phagocytosis. While the cDNA for C1qRP encodes a 631 amino acid membrane protein, Chinese hamster ovary cells transfected with the cDNA of the C1qRP coding region express a surface glycoprotein with the identical 126,000 Mr in SDS-PAGE as the native C1qRP. Use of glycosylation inhibitors, cleavage of the mature C1qRP with specific glycosidases, and in vitro translation of C1qRP cDNA demonstrated that both posttranslational glycosylation and the nature of the amino acid sequence of the protein contribute to the difference between its predicted m.w. and its migration on SDS-PAGE. These results verify that the cDNA cloned codes for the mature C1qRP, that C1qRP contains a relatively high degree of O-linked glycoslyation, and that C1qRP cross-linked directly by monoclonal anti-C1qRP or engaged as a result of cell surface ligation of SPA, as well as C1q and MBL, enhances phagocytosis.  (+info)

Alzheimer's beta-amyloid peptides can activate the early components of complement classical pathway in a C1q-independent manner. (2/737)

beta-Amyloid (beta-A) accumulates in the brain of patients with Alzheimer's disease (AD) and is presumably involved in the pathogenesis of this disease, on account of its neurotoxicity and complement-activating ability. Although assembly of beta-A in particular aggregates seems to be crucial, soluble non-fibrillar beta-A may also be involved. Non-fibrillar beta-A does not bind C1q, so we investigated alternative mechanisms of beta-A-dependent complement activation in vitro. On incubation with normal human plasma, non-fibrillar beta-A 1-42, and truncated peptide 1-28, induced dose-dependent activation of C1s and C4, sparing C3, as assessed by densitometric analysis of immunostained membrane after SDS-PAGE and Western blotting. The mechanism of C4 activation was not dependent on C1q, because non-fibrillar beta-A can still activate C1s and C4 in plasma genetically deficient in C1q (C1qd). In Factor XII-deficient plasma (F.XIId) the amount of cleaved C4 was about 5-10% less that in C1qd and in normal EDTA plasma; the reconstitution of F.XIId plasma with physiologic concentrations of F.XII resulted in an increased (8-15%) beta-A-dependent cleavage of C4. Thus our results indicate that the C1q-independent activation of C1 and C4 can be partially mediated by the activation products of contact system. Since the activation of contact system and of C4 leads to generation of several humoral inflammatory peptides, non-fibrillar beta-A might play a role in initiating the early inflammatory reactions leading to a multistep cascade contributing to neuronal and clinical dysfunction of AD brain.  (+info)

C1q binding to liposomes is surface charge dependent and is inhibited by peptides consisting of residues 14-26 of the human C1qA chain in a sequence independent manner. (3/737)

Complement activation by anionic liposomes proceeds by antibody-independent, C1q-initiated activation of the classical pathway. Purified C1q bound to anionic liposomes in an acidic lipid concentration-dependent manner. Saturation binding, but not the apparent association constant, was enhanced by increasing the cardiolipin content of the liposomes or decreasing either the pH or ionic strength of the reaction mixture. These observations indicate the involvement of electrostatic factors in the binding. A highly cationic region in the collagen-like domain of C1q comprised of residues 14-26 of the C1qA polypeptide chain was assessed for involvement in liposome binding. This region has previously been shown to mediate C1q binding to other immunoglobulin-independent activators of the classical pathway of complement. Peptides containing residues 14-26 of C1qA, denoted C1qA14-26, inhibited C1q binding to and complement activation by anionic liposomes. The inhibitory capacity of these cationic peptides had no sequence or conformation specificity. Rather, the amount of positive charge on the peptides was the determining factor. When present in excess, peptides with five cationic residues inhibited C1q binding and complement activation; however, C1q peptides with only two cationic residues did not. In addition to the C1qA14-26 region, other parts of C1q that contain cationic residues may also be involved in C1q binding to anionic liposomes.  (+info)

Cutting edge: C1q protects against the development of glomerulonephritis independently of C3 activation. (4/737)

C1q-deficient (C1qa-/-) mice develop antinuclear Abs and glomerulonephritis (GN) characterized by multiple apoptotic bodies. To explore the contribution of C3 activation to the induction of spontaneous GN, C1qa-/- mice were crossed with factor B- and C2-deficient (H2-Bf/C2-/-) mice. GN was present in 64% of the 45 C1qa/H2-Bf/C2-/- mice compared with 8% of the 65 H2-Bf/C2-/- mice and none of the 24 wild-type controls. IgG was detected in the glomeruli of diseased C1qa/H2-Bf/C2-/- kidneys. However, glomerular staining for C3 was absent. Increased numbers of glomerular apoptotic bodies were detected in undiseased C1qa/H2-Bf/C2-/- kidneys. These findings support the hypothesis that C1q may play a role in the clearance of apoptotic cells without the necessity for C3 activation and demonstrate that the activation of C3 is not essential for the development of GN in this spontaneous model of lupus-like disease.  (+info)

EMILIN, a component of the elastic fiber and a new member of the C1q/tumor necrosis factor superfamily of proteins. (5/737)

EMILIN (elastin microfibril interface located protein) is an extracellular matrix glycoprotein abundantly expressed in elastin-rich tissues such as blood vessels, skin, heart, and lung. It occurs associated with elastic fibers at the interface between amorphous elastin and microfibrils. Avian EMILIN was extracted from 19-day-old embryonic chick aortas and associated blood vessels and purified by ion-exchange chromatography and gel filtration. Tryptic peptides were generated from EMILIN and sequenced, and degenerate inosine-containing oligonucleotide primers were designed from some peptides. A set of primers allowed the amplification of a 360-base pair reverse transcription polymerase chain reaction product from chick aorta mRNA. A probe based on a human homologue selected by comparison of the chick sequence with EST data base was used to select overlapping clones from both human aorta and kidney cDNA libraries. Here we present the cDNA sequence of the entire coding region of human EMILIN encompassing an open reading frame of 1016 amino acid residues. There was a high degree of homology (76% identity and 88% similarity) between the chick C terminus and the human sequence as well as between the N terminus of the mature chick protein where 10 of 12 residues, as determined by N-terminal sequencing, were identical or similar to the deduced N terminus of human EMILIN. The domain organization of human EMILIN includes a C1q-like globular domain at the C terminus, a collagenous stalk, and a longer segment in which at least four heptad repeats and a leucine zipper can be identified with a high potential for forming coiled-coil alpha helices. At the N terminus there is a cysteine-rich sequence stretch similar to a region of multimerin, a platelet and endothelial cell component, containing a partial epidermal growth factor-like motif. The native state of the recombinantly expressed EMILIN C1q-like domain to be used in cell adhesion was determined by CD spectra analysis, which indicated a high value of beta-sheet conformation. The EMILIN C1q-like domain promoted a high cell adhesion of the leiomyosarcoma cell line SK-UT-1, whereas the fibrosarcoma cell line HT1080 was negative.  (+info)

Antibody-independent classical complement pathway activation and homologous C3 deposition in xeroderma pigmentosum cell lines. (6/737)

Of human malignantly transformed cell lines, xeroderma pigmentosum (XP) cell lines were found to be highly susceptible to homologous complement (C): cells were opsonized by C3 fragments on incubation with diluted normal human serum. C3 fragment deposition on XP cells was Ca2+-dependent and occurred on live cells but not UV-irradiated apoptotic cells. (Ca2+ is required for activation of the classical C pathway via C1q and the lactin pathway via mannose binding lectin (MBL), and the surface of apoptotic cells usually activates the alternative C pathway.) In this study we tested which of the pathways participates in XP cell C3 deposition. In seven cell lines that allowed C3 deposition (i), Clq was shown to be essential but MBL played no role in C activation, (ii) Cls but not MASP bound XP cells for activation, (iii) no antibodies recognizing XP cells were required for homologous C3 deposition, and (iv) the alternative pathway barely participated in C3 deposition. Furthermore, the levels of C-regulatory proteins for host cell protection against C, decay-accelerating factor (DAF, CD55) and membrane cofactor protein (MCP, CD46), were found to be relatively low in almost all XP cell lines compared with normal cells. These results indicate that XP cells activate the classical C pathway in an antibody-independent manner through the expression of a molecule which directly attracts C1q in a C-activating form, and that relatively low levels of DAF and MCP on XP cells facilitate effective C3 deposition. The possible relationship between the pathogenesis of XP and our findings is discussed.  (+info)

Neuronal protection in stroke by an sLex-glycosylated complement inhibitory protein. (7/737)

Glycoprotein adhesion receptors such as selectins contribute to tissue injury in stroke. Ischemic neurons strongly expressed C1q, which may target them for complement-mediated attack or C1qRp-mediated clearance. A hybrid molecule was used to simultaneously inhibit both complement activation and selectin-mediated adhesion. The extracellular domain of soluble complement receptor-1 (sCR1) was sialyl Lewis x glycosylated (sCR1sLex) to inhibit complement activation and endothelial-platelet-leukocyte interactions. sCR1 and sCR1sLex colocalized to ischemic cerebral microvessels and C1q-expressing neurons, inhibited neutrophil and platelet accumulation, and reduced cerebral infarct volumes. Additional benefit was conferred by sialyl Lewis x glycosylation of the unmodified parent sCR1 molecule.  (+info)

Role of complement component C1q in the IgG-independent opsonophagocytosis of group B streptococcus. (8/737)

We investigated the role of complement component C1q in the IgG-independent opsonophagocytosis of type III group B Streptococcus (GBS) by peripheral blood leukocytes. We report that C1q binds to type III GBS both in normal human serum deficient in IgG specific for type III capsular polysaccharide and in a low-ionic strength buffer. The dissociation constant Kd ranged from 2.0 to 5.5 nM, and the number of binding sites Bmax ranged from 630 to 1360 molecules of C1q per bacterium (CFU). An acapsular mutant strain of GBS bound C1q even better than the wild type, indicating that the polysaccharide capsule is not the receptor for C1q. In serum, binding of C1q to GBS was associated with activation of the classical complement pathway. However, normal human serum retained significant opsonic activity after complete depletion of C1q, suggesting that the serum contains a molecule that is able to replace C1q in opsonization and/or complement activation. Mannan-binding lectin, known to share some functions with C1q, appeared not to be involved, since its depletion from serum had little effect on opsonic activity. Excess soluble C1q or its collagen-like fragment inhibited phagocytosis mediated by normal human serum, suggesting that C1q may compete with other opsonins for binding to receptor(s) on phagocytes. We conclude that, although C1q binds directly to GBS, C1q binding is neither necessary nor sufficient for IgG-independent opsonophagocytosis. The results raise the possibility that additional unknown serum factor(s) may contribute to opsonization of GBS directly or via a novel mechanism of complement activation.  (+info)

C1q, the first component of the classical pathway of the complement system, interacts with various cell types and triggers a variety of cell-specific cellular responses, such as oxidative burst, chemotaxis, phagocytosis, etc. Different biological responses are attributed to the interaction of C1q with more than one putative cell-surface C1q receptor/C1q-binding protein. Previously, it has been shown that C1q-mediated oxidative burst by neutrophils is not linked to G-protein-coupled fMet-Leu-Phe-mediated response. In the present study, we have investigated neutrophil migration brought about by C1q and tried to identify the signal-transduction pathways involved in the chemotactic response. We found that C1q stimulated neutrophil migration in a dose-dependent manner, primarily by enhancing chemotaxis (directed movement) rather than chemokinesis (random movement). This C1q-induced chemotaxis could be abolished by an inhibitor of G-proteins (pertussis toxin) and PtdIns(3,4,5)P3 kinase (wortmannin and ...
Abstract: Recent studies have focused on elucidating the contribution of individual complement proteins to post-ischemic cellular injury. As the timing of complement activation and deposition after cerebral ischemia is not well understood, our study investigates the temporal pattern of C1q accumulation after experimental murine stroke. Brains were harvested from mice subjected to transient focal cerebral ischemia at 3, 6, 12, and 24 hr post reperfusion. Western blotting and light microscopy were employed to determine the temporal course of C1q protein accumulation and correlate this sequence with infarct evolution observed with TTC staining. Confocal microscopy was utilized to further characterize the cellular localization and characteristics of C1q deposition. Western Blot analysis showed that C1q protein begins to accumulate in the ischemic hemisphere between 3 and 6 hr post-ischemia. Light microscopy confirmed these findings, showing concurrent C1q protein staining of neurons. Confocal ...
The invention provides a series of G.alpha..sub.q protein variants that functionally couple to sensory cell receptors such as taste GPCRs (TRs) and olfactory GPCRs (ORs) in an overly promiscuous manner. According to the invention, the functional coupling can be determined, for example, by measuring changes in intracellular IP3, or calcium. In a particular embodiment, the G.alpha..sub.q protein variants can be expressed in mammalian cell lines or Xenopus oocytes, and then evaluated using calcium fluorescence imaging and electrophysiological recording.
Influence of the Gαq-protein on myocardial infarct size of the bone marrow-engrafted Gαq-knockout-mouse in a ischemia/reperfusion-model Platelets play a key role in the pathogenesis of an acute myocardial infarction. Thrombus formation, which is mediated by the activation of platelets, results in the occlusion of the coronary artery. On the other hand, agglutinated platelets in the small myocardial vessels impair the myocardial microcirculation. Due to their pro-inflammatory effects, platelets also contribute to the pathogenesis of ischemia/reperfusion injury. The myocardium of Gαq-deficient mice showed a reduced susceptibility to ischemia and reperfusion compared to that of wild-type mice (HEUER, in preparation). Activation of platelets lacking the Gαq-protein is markedly impaired, resulting not only in an increased haemophilia but also in a decreased thrombophilia of Gαq-deficient mice. A bone marrow transplantation was performed to investigate whether the impaired platelet-activation is ...
In a previous study we isolated a series of rat monoclonal antibodies to the human leukocyte common (LC) antigen and demonstrated that synergistic complement lysis was possible between IgG2b antibodies which recognised different epitopes. In this report we have examined the mechanisms that were involved in synergistic lysis. We found that the number of C1q binding sites increased from 30,000 to 40,000/cell using a single antibody to 90,000/cell when two IgG2b antibodies to different epitopes were used together. The affinity of C1q binding also increased approx. 3-fold for the synergistic pair, and there was a similar increase in the rate of C1 activation. Combinations of an IgG2b with IgG1 or IgG2a gave much smaller increases in the amount of C1q bound and in the rate of C1 activation. Despite the large number of C1q molecules bound with the optimal synergistic pair and the increased rate of C1 activation, lysis was inefficient in serum depleted of Factor D, suggesting a requirement for the alternative

Combining with the C1q component of the classical complement cascade and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
In addition to binding to cadherins, Gα12 and Gα13 were found to play important roles in other adhesion molecule-dependent cellular functions. In platelets lacking Gαq, coactivation of the Gαq- and Gα12/13-coupled thromboxane A2 receptor and the Gαi-coupled ADP receptor P2Y12 resulted in irreversible integrin αIIbβ3-mediated platelet aggregation (Nieswandt et al., 2002). Because Gαq-deficient platelets fail to respond to thromboxane A2 in αIIbβ3 activation assay, the study demonstrates converging signaling of Gα12/13 and Gαi, which is sufficient to overcome Gαq deficiency for αIIbβ3 activation. A recent study provided evidence for a role of the G12 subfamily in integrin signaling by demonstrating a direct interaction of Gα13 with the cytoplasmic domain of the β3 integrin (Gong et al., 2010). Ligand binding to the integrin αIIbβ3, as well as GTP loading of Gα13, promotes this interaction, supporting an outside-in signaling mechanism that favors cell spreading through the ...

It has been suggested that the human C1qRp is a receptor for the complement component C1q; however, there is no direct evidence for an interaction between C1q and C1qRp. In this study, we demonstrate that C1q does not show enhanced binding to C1qRp-transfected cells compared with control cells. Furthermore, a soluble recombinant C1qRp-Fc chimera failed to interact with immobilized C1q. The proposed role of C1qRp in the phagocytic response in vivo is also unsupported in that we demonstrate that this molecule is not expressed by macrophages in a variety of human tissues and the predominant site of expression is on endothelial cells. Studies on the rodent homolog of C1qRp, known as AA4, have suggested that this molecule may function as an intercellular adhesion molecule. Here we show that C1qRp is the Ag recognized by several previously described mAbs, mNI-11 and two anti-CD93 Abs (clones X2 and VIMD2b). Interestingly, mNI-11 (Fab) has been shown to promote monocyte-monocyte and ...

In invertebrates, the medicinal leech is considered to be an interesting and appropriate model to study neuroimmune mechanisms. Indeed, this non-vertebrate animal can restore normal function of its central nervous system (CNS) after injury. Microglia accumulation at the damage site has been shown to be required for axon sprouting and for efficient regeneration. We characterized HmC1q as a novel chemotactic factor for leech microglial cell recruitment. In mammals, a C1q-binding protein (C1qBP alias gC1qR), which interacts with the globular head of C1q, has been reported to participate in C1q-mediated chemotaxis of blood immune cells. In this study, we evaluated the chemotactic activities of a recombinant form of HmC1q and its interaction with a newly characterized leech C1qBP that acts as its potential ligand. Recombinant HmC1q (rHmC1q) was produced in the yeast Pichia pastoris. Chemotaxis assays were performed to investigate rHmC1q-dependent microglia migration. The involvement of a C1qBP-related
Results Anti-C1q antibodies were more prevalent than anti-ds DNA (n=41,93.2%)in pSLE patients of the current study, which correlated significantly with proteinuria and decreased complement levels (p,0.05). Anti-C1q levels were significantly elevated in patients with class III/IV nephritis compared II/V nephritis. pSLE patients with active nephritis at the time of sample collection demonstrated significantly elevated levels of anti-C1q antibodies compared to those without active nephritis. Anti-C1q antibodies were more sensitive and specific than anti-dsDNA in pSLE patients ...
Highlights: • A human monoclonal antibody against influenza virus was produced from a volunteer. • The antibody was generated from the PBMCs of the volunteer using the fusion method. • The antibody neutralized heterosubtypically group 1 influenza A viruses (H1 and H9). • The antibody targeted a novel epitope in globular head region of the hemagglutinin. • Sequences of the identified epitope are highly conserved among H1 and H9 subtypes. - Abstract: Most neutralizing antibodies elicited during influenza virus infection or by vaccination have a narrow spectrum because they usually target variable epitopes in the globular head region of hemagglutinin (HA). In this study, we describe a human monoclonal antibody (HuMAb), 5D7, that was prepared from the peripheral blood lymphocytes of a vaccinated volunteer using the fusion method. The HuMAb heterosubtypically neutralizes group 1 influenza A viruses, including seasonal H1N1, 2009 pandemic H1N1 (H1N1pdm) and avian H9N2, with a strong ...
1C1q Classical complement pathway inhibition: A novel strategy for the inhibition of Alzheimers disease pathogenesis INTRODUCTION 1.1 Alzheimers disease From the development of the Smallpox
Background: The C3bot1 protein (~23 kDa) from Clostridium botulinum ADP-ribosylates and thereby inactivates Rho. C3bot1 is selectively taken up into the cytosol of monocytes/macrophages but not of other cell types such as epithelial cells or fibroblasts. Most likely, the internalization occurs by a specific endocytotic pathway via acidified endosomes. Methodology/Principal Findings: Here, we tested whether enzymatic inactive C3bot1E174Q serves as a macrophage-selective transport system for delivery of enzymatic active proteins into the cytosol of such cells. Having confirmed that C3bot1E174Q does not induce macrophage activation, we used the actin ADP-ribosylating C2I (~50 kDa) from Clostridium botulinum as a reporter enzyme for C3bot1E174Q-mediated delivery into macrophages. The recombinant C3bot1E174Q-C2I fusion toxin was cloned and expressed as GST-protein in Escherichia coli. Purified C3bot1E174Q-C2I was recognized by antibodies against C2I and C3bot and showed C2I-specific enzyme activity ...
We are interested in interactions between the two fundamental cell types of the nervous system, neurons and glia. My laboratory seeks to understand how neuron-glia communication facilitates the formation, elimination and plasticity of synapses-the points of communication between neurons-during both healthy development and disease.. We focus on the role of neuron-glia and neural-immune interactions in the patterning of neural circuits. We and our collaborators have identified an unexpected role for glia and components of the innate immune system in synaptic pruning. We find that astrocytes induce neuronal expression of complement C1q, the initiating protein of the classical complement cascade (which tags unwanted cells and debris for elimination in the immune system). C1q and downstream complement proteins target synapses and are required for synapse elimination in the developing visual system. Importantly, we find that C1q becomes aberrantly upregulated and is relocalized to synapses in the ...

To evaluate whether ischemic myocardium releases molecules that react with the first component of complement, we studied cardiac lymph from eight dogs before and at intervals after coronary artery occlusion and reperfusion. Before occlusion, the dogs were injected intravenously with radiolabeled human C1q. Labeled C1q could be detected in the cardiac lymph within minutes following injection. Rabbit antisera, prepared against substances precipitated from postreprefusion cardiac lymph by anti-human C1q, also reacted with specific constituents of isolated cardiac sarcoplasmic reticulum and mitochondria. To evaluate whether mitochondria are the source of these C1q-binding proteins, we isolated intramyofibrillar and subsarcolemmal mitochondria from canine heart and incubated sonicates of these with purified C1q, immobilized on nitrocellulose. Molecules bound to the immobilized C1q were removed with 0.1% sodium dodecyl sulfate, fractionated under reducing conditions by polyacrylamide gel ...
The C-reactive protein (CRP) is a cyclic pentameric pentraxin family acute phase protein compound of five identical noncovalently bound nonglycosylated subunits (each subunit 24 kDa; physiologic CRP molecule 117,5 kDa). CRP is produced by the liver and its plasma levels rise dramatically during inflammatory processes occuring in the body. CRP is an initiator of classical complement cascade, binds to several nuclear components (chromatin, histones, etc.) and is also believed to play an important role in innate immunity. Patients with elevated basal levels of CRP are at increased risk for hypertension and cardiovascular disease ...
C1q is the first subcomponent of the classical pathway of the complement system and a major connecting link between innate and acquired immunity. As a versatile charge pattern recognition molecule, C1q is capable of engaging a broad range of ligands via its heterotrimeric globular domain (gC1q) which is composed of the C-terminal regions of its A (ghA), B (ghB) and C (ghC) chains. Recent studies using recombinant forms of ghA, ghB and ghC have suggested that the gC1q domain has a modular organization and each chain can have differential ligand specificity. The crystal structure of the gC1q, molecular modeling and protein engineering studies have combined to illustrate how modular organization, charge distribution and the spatial orientation of the heterotrimeric assembly offer versatility of ligand recognition to C1q. Although the biochemical and structural studies have provided novel insights into the structure-function relationships within the gC1q domain, they have also raised many unexpected issues
Previous studies have shown that complement opsonization is required for efficient phagocytosis of dying cells in vitro (6, 7) and that uptake of these opsonized cells is associated with expression of the antiinflammatory cytokine, TGF-β (6). Three observations, namely that C1q binds to apoptotic cells in vitro (10), that apoptotic cells accumulate in the kidneys of mice deficient in C1q (4), and that complement activation on apoptotic cells promotes phagocytosis of these cells by macrophages in vitro, suggest a pivotal role for complement in noninflammatory clearance of dying cells. Here, we report that IgM antibodies in normal individuals are quantitatively most important for C1q binding and C3b/bi activation on the apoptotic cell surface and that these natural antibodies bind to lysophosphorylcholine that is exposed on cells undergoing apoptosis.. Since IgM bound to apoptotic cells by the Fab, rather than the Fc, portion of the Ig, binding could be attributed to antibody recognition of an ...
TY - JOUR. T1 - The mouse C1q genes are clustered on chromosome 4 and show conservation of gene organization. AU - Petry, F. AU - McClive, PJ. AU - Botto, M. AU - Morley, Bernard J. AU - Morahan, G. AU - Loos, M. PY - 1996/4. Y1 - 1996/4. N2 - Mouse complement component C1q is a serum glycoprotein which consists of six A chains, six B chains and six C chains. The three polypeptides are 223, 228, and 217 residues long, respectively, and are encoded by three genes. DNA probes for mouse C1q A, B, and C chains were hybridized to Southern blots of DNA obtained from various inbred mouse strains. On the basis of fragment length polymorphisms, two different alleles of each of the genes could be identified. The distribution of these alleles was determined in the BXD and LXPL recombinant inbred strain series. Comparison with previously reported strain distribution patterns shows that the genes encoding mouse C1q map to the same locus on distal chromosome 4. Overlapping clones spanning the entire gene ...

effect. Instead of specifying gamma directly, we select two quantities that are more intuitive and together define gamma. The first is theta, a threshold value that defines a high-impact mutation . The second is q, the fraction of mutations that exceed this threshold in their effect. For example, a user can first define a high-impact mutation as one that results in 10% or more change in fitness (theta = 0.1) relative to the scale factor and then specify that 0.001 of all mutations (q = 0.001) be in this category. Inside the code the value of is computed that satisfies these requirements. We reiterate that Mendel uses the same value for gamma, and thus the same values for theta and q, for both favorable and deleterious mutations. Figure 3.1 shows the effect of the parameter q on the shape of the distribution of fitness effect. Note that for each of the cases displayed the large majority of mutations are nearly neutral, that is, they have very small effects. Since a utation s effect on fitness can ...
Kur një rrëfim na merr me vete, përvetësojmë identitetin e personazhit dhe e stimulojmë përvojën e tij në jetën reale Shumë shpesh na ndodh që gjatë leximit të një libri, të apasionohemi aq shumë pas historisë, sa të fillojmë të identifikohemi me protagonistin e saj duke kërkuar pika të përbashkëta me të ose të kopjojmë sjelljen dhe mendimet e tij. Sipas një studimi të Universitetit shtetëror të Ohajos, ky është një proces shumë normal që studiuesit e kanë quajtur përvetësimi i përvojës, ose procesi spontan që çon në përvetësimin e identitetit të një personazhi në një rrëfim të shkruar në një libër dhe më pas stimulimi i përvojës së tij në jetën reale. Pra, në një farë mënyrë, jeni duke humbur brenda historisë së shkruar (në mënyrë letrare) dhe e gjeni veten si pa kuptuar duke vepruar dhe menduar njësoj si protagonisti i romanit, për të arritur deri atje sa të modifikoni sjelljen tuaj në mënyrë që të jetë e ...
Antioksidantët luajnë një rol vendimtar në parandalimin e fillimit të sëmundjes dhe mund të bëjnë të gjitha ndryshimet në përcaktimin nëse fëmijët zhvillojnë ose jo intolerancën e glukozës. Sipas një studimi të ri të Spitalit të Fëmijëve të Filadelfias (CHP), gratë që konsumojnë sasi të mëdha të antioksidantëve para dhe gjatë shtatëzanive të tyre, mund të mbrojnë fëmijët e tyre nga diabeti dhe obeziteti, transmeton Gazeta Shneta.. Duke vënë në dukje se dietat e larta në yndyrnat e dëmshme dhe karbohidratet shkaktojnë stres oksidativ që çon në obezitetin dhe diabetin e fëmijës, studiuesit vendosën të studiojnë efektin që antioksidantët kanë në lehtësimin e fillimit të tyre. Ekipi ushqeu katër grupe të minjëve në një dietë të lartë me yndyrë, kolesterol, një dietë të shëndetshme dhe një tjetër më të ekuilibruar. Dy grupet e para morën dietat e tilla pa antioksidantë shtesë, ndërsa dy të tjerat pranuan antioksidantë ...
