The immune system may interplay between Chlamydia pneumoniae infection and coronary artery disease (CAD). Major histocompatibility complex genes regulate innate and adaptive immunity. Patients with CAD (n = 100) and controls (n = 74) were enrolled. Human leukocyte antigens (HLA-A, HLA-B, and HLA-DRB1), four lymphotoxin alpha single-nucleotide polymorphisms, and complement C4A and C4B allotypes ...
the link between il-13 and bronchial hyper-responsiveness has brought this cytokine as a potential therapeutic target for asthma and allergic diseases. at the present study, we address the role of b cell derived il-13 in the ige and other immunoglobulin development. antisense oligo for human il-13 m-rna was used to study ige down regulation. human b-lymphocytes were purified by positive selecti...
B cells have long played an enigmatic role in the scenario of multiple sclerosis pathogenesis. This review summarizes recent progress in our understanding of B-cell trafficking, survival, and differentiation in the central nervous system (CNS). We propose four possible routes of intrathecal immunoglobulin-producing cells. The inflammatory CNS provides a unique, B-cell-friendly environment, in w...
B-1 B cells produce circulating natural antibodies that provide "innate-like" protection against bacterial and viral pathogens. They also provide adaptive responses to blood and air-borne pathogens. B lymphocyte-induced maturation protein 1 (Blimp-1) is a transcriptional repressor that is required for the formation of B-2-derived antibody-secreting plasma cells. In this study, we used mice lack...
The Sézary syndrome is a frequently lethal disease characterized by circulating malignant cells of thymus-derived (T)-cell origin. The capacity of circulating malignant lymphocytes from patients with this syndrome to synthesize immunoglobulins and to function as helper or suppressor cells regulating immunoglobulin synthesis by bone marrow-derived (B) lymphocytes was determined. Peripheral blood...
The concentration of committed granulocytic progenitor cells (CFU-C) in functionally unique subpopulations of human peripheral blood mononuclear cells has been determined by the in vitro methyl-cellulose assay. Using immunoabsorbent column chromatography and rosette-depletion techniques, we have demonstrated that CFU-C, although not present in either purified T or B lymphocyte populations, are ...
We have previously shown that the neural adhesion molecules L1 and NCAM interact with each other to form a complex which binds more avidly to L1 than L1 to L1 alone (Kadmon, G., A. Kowitz, P. Altevogt, and M. Schachner. 1990a. J. Cell Biol. 110:193-208). This cis-association between L1 and NCAM is carbohydrate-dependent (Kadmon, G., A. Kowitz, P. Altevogt, and M. Schachner. 1990b. J. Cell Biol....
In murine plasmacytoma and human Burkitt's lymphoma cells, one allele of c-myc is translocated into one of the immunoglobulin loci, resulting in a characteristic pattern of deregulated c-myc transcription. Translocation events between c-myc and the IgH locus segregate c-myc and the IgH intron enhancer to different reciprocal products in all plasmacytomas and in most Burkitt's lymphoma cells, su...
Interactions between killer immunoglobulin-like receptors (KIRs) and their HLA-A, -B, and -C ligands diversify the functions of human natural killer cells. Consequently, combinations of KIR and HLA genotypes affect resistance to infection and autoimmunity, success of reproduction and outcome of hematopoietic cell transplantation. HLA-C, with its C1 and C2 epitopes, evolved in hominids to be spe...
