Transcriptional stalling in B-lymphocytes
B cells utilize three DNA alteration strategies-V(D)J recombination, somatic hypermutation (SHM) and class switch recombination (CSR)-to somatically mutate their genome, thereby expressing a plethora of antibodies tailor-made against the innumerable antigens they encounter while in circulation. Of these three events, the single-strand DNA cytidine deaminase, Activation Induced cytidine Deaminas...
متن کاملNKT Cell Responses to B Cell Lymphoma
Natural killer T (NKT) cells are a unique subset of CD1d-restricted T lymphocytes that express characteristics of both T cells and natural killer cells. NKT cells mediate tumor immune-surveillance; however, NKT cells are numerically reduced and functionally impaired in lymphoma patients. Many hematologic malignancies express CD1d molecules and co-stimulatory proteins needed to induce anti-tumor...
متن کاملB Cell–dependent T Cell Responses
Contact sensitivity (CS) is a classic example of in vivo T cell immunity in which skin sensitization with reactive hapten leads to immunized T cells, which are then recruited locally to mediate antigen-specific inflammation after subsequent skin challenge. We have previously shown that T cell recruitment in CS is triggered by local activation of complement, which generates C5a that triggers C5a...
متن کاملGrb2 regulates B-cell maturation, B-cell memory responses and inhibits B-cell Ca2+ signalling.
Grb2 is a ubiquitously expressed adaptor protein, which activates Ras and MAP kinases in growth factor receptor signalling, while in B-cell receptor (BCR) signalling this role is controversial. In B cell lines it was shown that Grb2 can inhibit BCR-induced Ca(2+) signalling. Nonetheless, the physiological role of Grb2 in primary B cells is still unknown. We generated a B-cell-specific Grb2-defi...
متن کاملGenetical Control of B - Cell Responses
We and others have recently described the selective unresponsiveness of C3H/HeJ mice to the B-cell mitogen lipopolysaccharide from Escherichia coli : 055:B5 (LPS)' (1-3) . We have also characterized this unresponsiveness as a pure B-cell defect, since it does not depend upon the inactivation of the mitogen or other trivial in vivo or in vitro conditions particular to these mice, nor is it cause...
