Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.
Protein factor(s) released by sensitized lymphocytes (and possibly other cells) that inhibit the movement of LEUKOCYTES, especially polymorphonuclear cells, away from their site of release. Assays for these factors are used as tests for cellular immunity. Two of the common assays are the LEUKOCYTE MIGRATION CAPILLARY TUBE TECHNIQUE (LMCT) and the LEUKOCYTE MIGRATION AGAROSE TEST (LMAT).
Proteins released by sensitized LYMPHOCYTES and possibly other cells that inhibit the migration of MACROPHAGES away from the release site. The structure and chemical properties may vary with the species and type of releasing cell.
Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.
White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).
The movement of cells from one location to another. Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell.
A protein extracted from boiled culture of tubercle bacilli (MYCOBACTERIUM TUBERCULOSIS). It is used in the tuberculin skin test (TUBERCULIN TEST) for the diagnosis of tuberculosis infection in asymptomatic persons.

White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

An active immunizing agent and a viable avirulent attenuated strain of Mycobacterium tuberculosis, var. bovis, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.
One of several skin tests to determine past or present tuberculosis infection. A purified protein derivative of the tubercle bacilli, called tuberculin, is introduced into the skin by scratch, puncture, or interdermal injection.
Test for cell-mediated antitumor immunity and related serum blocking factors based on the finding that leukocytes from cancer patients, but not from controls, when mixed in vitro with antigenic extracts of tumors of the same histological type, undergo a diminution in their normal adherence to glass surfaces. Sera from tumor-bearing patients block the LAI reaction of their own leukocytes or those of other patients with the same type of tumor.
A specific immune response elicited by a specific dose of an immunologically active substance or cell in an organism, tissue, or cell.
Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.
Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).
Specific assays that measure the migration of cells. They are commonly used to measure the migration of immune cells in response to stimuli and the inhibition of immune cell migration by immunosuppressive factors.

Substances of fungal origin that have antigenic activity.
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
The production of ANTIBODIES by proliferating and differentiated B-LYMPHOCYTES under stimulation by ANTIGENS.
Substances elaborated by bacteria that have antigenic activity.
A series of steps taken in order to conduct research.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Hypersensitivity pneumonitis: experimental production in calves with antigens of Micropolyspora faeni. (1/850)

Pneumonitis was induced in calves by exposure to aerosols of Micropolyspora faeni with or without prior sensitization of the animals by subcutaneous injection of antigen. The pneumonitis primarily involved centrolobular areas and was characterized by alveolar septal thickening and loss of air space by cellular infiltration. Vasculitis and focal haemorrhage occurred in certain individuals and haemoproteinaceous exudate appeared within septa and alveolar lumina. The pneumonitis was compared with human farmer's lung, pneumonitis of housed cattle and other experimental hypersensitivity pneumonitides.  (+info)

Lymphocyte proliferation inhibitory factor (PIF) in alcoholic liver disease. (2/850)

Lymphocyte proliferation inhibitory factor (PIF) was determined in the supernatants of PHA-stimulated lymphocytes from patients with alcoholic liver disease. PIF was assayed by determining inhibition of DNA synthesis in WI-38 human lung fibroblasts. A two-fold greater inhibition in thymidine incorporation into DNA by lung fibroblasts was observed in supernatants of PHA stimulated lymphocytes from patients with alcoholic hepatitis or active Laennec's cirrhosis as compared with that found in control subjects or patients with fatty liver. It is suggested that decreased liver cell regeneration seen in some patients with alcoholic hepatitis may be due to increased elaboration of PIF.  (+info)

Macrophage electrophoretic mobility (MEM) with myelin basic protein. (3/850)

Lymphocytes from a total of 161 subjects, including normal controls and patients with malignant and non-malignant conditions, have been investigated for their response to myelin basic protein, using the macrophage electrophoretic mobility (MEM) test. It has been confirmed that there was a high level of association between clinically evident cancer and a positive response. Lymphocytes from 24/25 patients with non-malignant inflammatory and ischaemic diseases also gave positive responses. In 46 patients with breast lumps studied before mastectomy or biopsy, the test was positive in 15/19 cases which proved to be malignant and in 5/27 which proved benign on histological examination. In its present form the test is not sufficiently reliable for the diagnosis of early cancer. Our results suggest that tissue necrosis in malignant and non-malignant conditions may be one of the factors resulting in sensitization to antigenic determinants present in preparations of myelin basic protein. Despite its technical difficulties, the test may provide a means of examing some aspects of immune recall not readily revealed by other test systems.  (+info)

Leucocyte migration inhibition with inner and outer membranes of mitochondria and insoluble hepatocyte surface membranes prepared from rat liver in patients with chronic hepatitis and cirrhosis. (4/850)

Patients with chronic liver disease were tested for delayed hypersensitivity to the outer and the inner membranes of mitochondria (OMM and IMM) and the insoluble hepatocyte-surface membranes (IHSM), prepared from rat livers, by means of leucocyte migration inhibition technique. Positive reaction to OMM was found in 37% of patients with chronic persistent hepatitis and 35% of those with chronic active hepatitis and 43% of those with liver cirrhosis (P less than 0-05). That to IMM was 55%, 43% and 36% (P less than 0-05) and to IHSM was 37%, 47% and 45% respectively (P less than 0-05). IHSM was found to contain liver-specific components and patients with positive response to IHSM did not reveal at all a positive reaction to rat renal cell-surface membranes. The incidence of positive response to IHSM was significantly higher (54-2%) in patients with the present or previous infection with HBAg than in HBAg-non-infected patients (21-4%) (P less than 0-05). And there seemed to be a good correlation between a degree of cellular response to purified HBsAg and that to IHSM in these HBAg-infected patients. No correlation, however, was found between that to purified HBsAg and that to OMM or IMM in the same patients. This suggested that the cellular response to either HBsAg or IHSM, both related closely, may play a role in the perpetuation of chronic liver disease.  (+info)

Cell-mediated immune responses in owl monkeys (Aotus trivirgatus) with trachoma to soluble antigens of Chlamydia trachomatis. (5/850)

The first temporal study of the cell-mediated immune responses (CMI) following ocular infections with Chlamydia trachomatis is presented. We examined the CMI of owl monkeys infected with trachoma to soluble antigens of C. trachomatis by leucocyte migration inhibition (LIF) and delayed hypersensitivity skin testing. Delayed hypersensitivity of a systemic nature developed after a local eye infection in owl monkeys; clearance of inclusions from conjunctival cells coincided with the onset of this response. The association of eye secretion and circulating antibodies with recovery from primary infection was not so striking. Both cellular and humoral immune responses persisted for at least 2 months, at which time all test animals were completely resistant to re-infection. The elicitation of cell-mediated immune reactions with solubilized chlamydial antigens may permit the isolation of specific antigens involved in the generation of protective immunity in the owl monkey model.  (+info)

Acquired cellular resistance, delayed hypersensitivity, and altered macrophage migration in Listeria monocytogenes-infected guinea pigs. (6/850)

A Listeria monocytogenes infection in guinea pigs was used to study the interrelationship between antigen-induced macrophage migration inhibition, delayed-type hypersensitivity, and acquired cellular resistance. Early after infection (at 2 and 7 days), very significant enhancement of macrophage migration was observed. Migration inhibition was detected beginning on day 14 and was uniformly observed only on day 21 of the infection, after which a shift again to enhancement was seen. The early detection (by day 2) of migration enhancement suggested that this assay may be more sensitive than assessment of delayed type hypersensitivity in vivo, which in this system was first detectable only on day 4. Acquired cellular resistance, as measured by enhanced survival following a high dose challenge with Listeria, was present from day 7 after infection until at least day 60. By splenic clearance studies, however, acquired cellular resistance was present only until day 14 after infection, suggesting that in this system splenic clearance was not a very reliable criterion for measuring acquired cellular resistance.  (+info)

Promotion of neutrophil chemotaxis through differential regulation of beta 1 and beta 2 integrins. (7/850)

Migration of neutrophils requires sequential adhesive and deadhesive interactions between beta 1 and beta 2 integrins and components of the extracellular matrix. Prompted by reports that describe interaction of soluble beta-glucan with the beta 2 integrin Mac-1, a role for beta-glucan in regulation of integrin-mediated migration was investigated. Neutrophil migration in response to fMLP was assessed using an agarose overlay method with slides precoated with fibronectin (Fn) +/- beta-glucan. On Fn, random migration in excess of directed migration was observed. In contrast, migration on Fn + beta-glucan was directional, with marked diminution of random migration. This conversion of random to directed migration was seen neither when Fn was supplemented with alternative polysaccharides nor when beta-glucan was applied to other components of the extracellular matrix. This effect of beta-glucan was shown to be cation dependent and to be effected by Arg-Gly-Asp-containing peptides consistent with an integrin-mediated event. mAb inhibition studies demonstrate that beta-glucan effects this shift toward directed migration through suppression of migration mediated by Mac-1 and very late Ag 5 and enhancement of very late Ag 3-mediated migration. Adhesion assays suggest that the prochemotactic influence of beta-glucan is due, in part but not entirely, to modulation of PMN adhesion to Fn. In summary, these data support a novel role for beta-glucan in regulation of beta 1- and beta 2-mediated neutrophil migration on Fn.  (+info)

Inhibition of tyrosine kinase activation blocks the down-regulation of CXC chemokine receptor 4 by HIV-1 gp120 in CD4+ T cells. (8/850)

Because the binding of HIV-1 envelope to CD4 initiates a configurational change in glycoprotein 120 (gp120), enabling it to interact with fusion coreceptors, we investigated how this process interferes with the expression and function of CXC chemokine receptor 4 (CXCR4) in CD4+ T lymphocytes. A recombinant gp120 (MN), after preincubation with CD4+ T lymphocytes, significantly inhibited the binding and chemotaxis of the cells in response to the CXCR4 ligand stromal cell-derived factor-1alpha (SDF-1alpha), accompanied by a markedly reduced surface expression of CXCR4. gp120, but not SDF-1alpha, induced rapid tyrosine phosphorylation of src-like kinase p56lck in CD4+ T cells, whereas both gp120 and SDF-1alpha caused phosphorylation of the CXCR4. The tyrosine kinase inhibitor herbimycin A abolished the phosphorylation of p56lck and CXCR4 induced by gp120 in association with maintenance of normal expression of cell surface CXCR4 and a migratory response to SDF-1alpha. Thus, a CD4-associated signaling molecule(s) including p56lck is activated by gp120 and is required for the down-regulation of CXCR4.  (+info)

In seven patients with chronic beryllium disease (Be) the Be lymphocyte transformation test was positive in 100%, independent of steroid therapy, and was reproducible. The Be macrophage migration inhibition test was only positive in four of seven patients (57%) not on steroids, and was not reproducible. In 72 potentially exposed healthy beryllium workers the lymphocyte transformation test was negative in all subjects. The macrophage test was positive in four of 78 and again the results were not reproducible. The workers with positive results showed no differences in age, type or duration of employment from those with negative results and showed no evidence of disease. In addition, the macrophage test was positive in two of 45 non-exposed control subjects. We also confirmed the above advantages of the lymphocyte transformation technique by using tuberculin antigen (PPD). The PPD lymphocyte transformation test gave positive results in approximately 60% of healthy beryllium workers, but the PPD ...

Cellular hypersensitivity to an extract of human pancreas, using the leucocyte migration test (LMT), was found in twenty-nine of 101 diabetic and eight of fifty normal control subjects. However, the difference in response between diabetics and controls was confined to young insulin-dependent patients, there being no distinction between normal subjects and older diabetics treated by diet or oral hypoglycemic agents. The use of rat liver mitochondria and bovine insulin as antigens in the LMT did not induce inhibition of leucocyte migration in diabetics or controls.. ...
Migration of monocytic-phagocytic cells from guinea pigs immunized with complete Freunds adjuvant is regularly and specifically inhibited in tissue culture by 5 to 10µg/ml of PPD. Migration of leukocytes and spindle cells from such animals is inhibited by PPD less consistently and to a lesser degree.. Cutaneous hypersensitivity to PPD in these animals develops 5 days after adjuvant immunization; at this time migration of mononuclear cells from explants of lung and regional node is inhibited by addition of 10 µg/ml of PPD. Splenic cells become sensitive 2 to 3 weeks after immunization and hepatic macrophages become sensitive only several weeks later.. Cellular hypersensitivity to antigen, as measured by this technique, develops in guinea pigs infected with Histoplasma or immunized with emulsions of complete Freunds adjuvant and T4 bacteriophage, bovine γ-globulin, human γ-globulin, or picrylated guinea pig skin. The sensitivity is specific for the immunizing antigen.. Serum from immunized ...

Wheat gluten derived antigens have been tested for their ability to inhibit the migration of leucocytes from healthy subjects and patients with coeliac disease. Three preparations of a water soluble fraction (Frazers fraction III, FIII) of partial peptic tryptic digests of wheat gluten had different effects in a direct (one stage) assay. Subfractions B and B2 caused migration inhibition of leucocytes from patients with treated coeliac disease but not of leucocytes from healthy volunteers or patients with Crohns disease or ulcerative colitis. This migration inhibition seems to be specific for gluten fractions because maize zein fraction B, beta-lactoglobulin and ovalbumin did not cause it. The sensitivity of coeliac leucocytes to fraction B is not related to factors present in coeliac serum as the migration of leucocytes from healthy individuals preincubated with coeliac sera was not inhibited. Puromycin diminished inhibition by fraction B, which was active at 1.2 micrograms/ml in an indirect (two
As heparan sulfate proteoglycans (HSPGs) are known as co-receptors to interact with numerous growth factors and then modulate downstream biological activities, overexpression of HS/HSPG on cell surface acts as an increasingly reliable prognostic factor in tumor progression. Cell penetrating peptides (CPPs) are short-chain peptides developed as functionalized vectors for delivery approaches of impermeable agents. On cell surface negatively charged HS provides the initial attachment of basic CPPs by electrostatic interaction, leading to multiple cellular effects. Here a functional peptide (CPP|i|ecp|/i|) has been identified from critical HS binding region in hRNase3, a unique RNase family member with|i| in vitro|/i| antitumor activity. In this study we analyze a set of HS-binding CPPs derived from natural proteins including CPP|i|ecp|/i|. In addition to cellular binding and internalization, CPP|i|ecp|/i| demonstrated multiple functions including strong binding activity to tumor cell surface with higher HS
Glutathione S-transferase activity was identified in cytosol from human lymphoid-cell lines and peripheral leucocytes (polymorphonuclear-leucocyte/monocyte and small-lymphocyte fractions) and compared with human liver enzyme. The findings of closely similar elution volume in gel filtration, substrate (1-chloro-2,4-dinitrobenzene) and inhibitory (probenecid) kinetics indicate that the liver, leucocyte and lymphoid-cell transferases are closely related. The interaction of reduced glutathione and 1-chloro-2,4-dinitrobenzene was shown to occur in intact-lymphoid-cell culture, to be linear with time and quantity of cells and to have kinetics similar to those of the enzyme reaction catalysed by cytosol. ...

Cellular immunity to the hepatitis B surface antigen (HBsAg) and a liver-specific lipoprotein was studied, using the leucocyte migration test, in 38 asymptomatic blood donors found to have HBsAg in the serum. Sensitization to HBsAg was found in 26% and was related to the presence of liver damage, being detected in 47% of those with elevated serum aspartate aminotransferase but in only 13% with normal enzyme levels. The frequency of sensitization to this antigen in those with chronic persistent or chronic aggressive hepatitis on biopsy was also higher than in those with unrelated or minimal changes ...

PY - 2006/12. Y1 - 2006/12. N2 - We showed previously that terbinafine, an allylamine with fungicidal activity, could inhibit angiogenesis by suppressing the endothelial cell proliferation. In the present study, we further showed that terbinafine (0-120 μmol/L) dose dependently inhibited the adhesion and migration of human umbilical vascular endothelial cells (HUVEC). Western blot analysis showed that terbinafine decreased the levels of Ras protein and membrane-bound RhoA protein. Moreover, the terbinafine-induced migration inhibition in HUVEC was prevented by pretreatment with farnesol or geranylgeraniol. Pretreatment of HUVEC with Ras inhibitor peptide or a ROCK (a kinase associated with RhoA for transducing RhoA signaling) inhibitor, Y27632, abolished the farnesol- or geranylgeraniol-induced prevention ...

|p|One of the first cytokines described, MIF (macrophage migration inhibitory factor) was originally identified in studies of delayed hypersensitivity reactions where it was shown to inhibit macrophage migration. It is an important mediator of the innate immune response with potential roles in the pathophysiology of inflammatory, autoimmune, and neoplastic disorders. The human MIF gene encodes a 115 amino acid, 12.5 kDa secreted protein. Crystallographic studies suggest that MIF exists as a homotrimer, although some reports show that it may exist as a dimer or monomer as well. Although MIF exhibits no homology with other known cytokines, it shares structural homology with several bacterial enzymes. It has been speculated that MIF is an inflammatory mediator possibly associated with rheumatoid arthritis (RA) severity.|/p|

Methods The migratory ability of peripheral neutrophils from healthy donors (HD) and different tumour cell lines (myeloid leukaemia HL60 cells and human pancreatic adenocarcinoma COLO357 cells) was analysed in response to N-Formylmethionyl-leucyl-phenylalanine (FMLP) or Protease-activated receptor 2 (Par-2) agonist. Because it has been shown before [2], IgGs from HD and SSc patients were used as additional stimulus for migration. Neutrophils and HL60 cells were preincubated (1h) with sitaxentan or ambrisentan, respectively, before being tested for migration (1h) using the Transwell assay. COLO357 cells were incubated (48h) in the presence of sitaxentan and migration was tested in the Oris Pro Cell assay.

Macrophage migration inhibitory factor (MIF), a proinflammatory cytokine, is considered an attractive therapeutic target in multiple inflammatory and autoimmune disorders. In addition to its known biologic activities, MIF can also function as a tautomerase. Several small molecules have been reported to be effective inhibitors of MIF tautomerase activity in vitro. Herein we employed a robust activity-based assay to identify different classes of novel inhibitors of the catalytic and biological activities of MIF. Several novel chemical classes of inhibitors of the catalytic activity of MIF with IC(50) values in the range of 0.2-15.5 microm were identified and validated. The interaction site and mechanism of action of these inhibitors were defined using structure-activity studies and a battery of biochemical and biophysical methods. MIF inhibitors emerging from these studies could be divided into three categories based on their mechanism of action: 1) molecules that covalently modify the catalytic site at
Peptides , Prion Protein (PrP) Fragments , PrP (106-126); This peptide increases membrane microviscosity, intracellular Ca2+ concentration and cell migration in circulating leucocytes, and oxygen production in monocytes and neutrophils. It also induces apoptotic cell death and impairment of L-type voltage-sensitive calcium channel activity in the GH3 cell lines. PrP (106 126) stimulates leucocyte migration in a dose-dependent manner.; KTNMKHMAGAAAAGAVVGGLG; H-Lys-Thr-Asn-Met-Lys-His-Met-Ala-Gly-Ala-Ala-Ala-Ala-Gly-Ala-Val-Val-Gly-Gly-Leu-Gly-OH
Macrophage migration inhibitory factor (MIF) is an evolutionary conserved 12.5-kDa protein mediator with multiple functions in innate and acquired immunity. Upon leaderless secretion, MIF acts as a typical inflammatory cytokine, but there is no structural homology between MIF and any of the known cy …

  • RhoA/ROCK inhibition reduces focal adhesions and traction forces, while promoting a novel gliding mode of migration. (elsevier.com)
  • These effects were prevented by co-transfection of the cell with constitutively active RhoA construct (RhoA V14). (elsevier.com)
  • Integrin-mediated cell spreading and the formation of focal adhesions were down-regulated by wild-type PTEN but not by PTEN with an inactive phosphatase domain. (sciencemag.org)
  • and biochemical processes governing the active motion of the cell (for a review, see Demuth & Berens (2004) ). (royalsocietypublishing.org)
  • Cell health and viability measurements provide essential insight into a broad range of biological processes and treatment responses. (biotekinstruments.it)
  • The processes underlying mammalian cell migration are believed to be consistent with those of (non-spermatozooic) locomotion. (wikipedia.org)
  • It is possible that both underlying processes contribute to cell extension. (wikipedia.org)
  • Both processes required the transportation of lipid rafts to the cell surface to deliver signaling components. (frontiersin.org)
  • Over these serial processes, the cell undergoes multiple attachments and detachments to endothelial cells ( 1 ). (frontiersin.org)
  • Here, we found that E 2 treatment decreased cell proliferation and cell cycle-regulating factors such as cyclin A, cyclin D1 and cyclin E. At the same time, E 2 significantly inhibited cell migration and migration-related factors such as uPA, tPA, MMP-2, and MMP-9. (elsevier.com)
