Receptor Selection in B and T Lymphocytes

Wnt signaling in B and T lymphocytes.

Wnt signaling has been shown to be critical for proper embryonic development as well as growth regulation of certain adult tissues. Defects in Wnt pathways have additionally been associated with a number of human cancers. However, it is only recently that a role for Wnts in the immune system has come to be appreciated. Wnts have now been shown to play significant roles in early stage developmen...

analysis of t cell receptor vβ diversity in peripheral cd4+ and cd8+ t lymphocytes obtained from patients with chronic severe hepatitis b

conclusions the cd4+ and cd8+ tcr vβ gene families undergo clonal expansion in cshb patients, and cd8+ t cells play a major role in the pathogenesis of cshb. moreover, the conserved motifs and limited use of joining region genes observed in the cshb patients of this cohort indicated that similar antigenic epitopes are recognized. results the number of oligoclonal or monoclonal expansion tcr vβ ...

Surface Globulins of T and B Lymphocytes

The concept that lymphocytes recognize antigens by means of a surface receptor molecule of immunoglobulin (Ig) character has come to be widely accepted (1-3). Direct study of such receptors in the mouse by means of antiglobulin reagents labeled with either fuorescent (4, 5) or radioisotope (3, 6-8) markers has revealed a dense coating of surface immunoglobulins on nonthymus-derived or B lymphoc...

Mice Lacking Mature T and B Lymphocytes

Tespa1 is a novel inositol 1,4,5-trisphosphate receptor binding protein in T and B lymphocytes

Tespa1 has been recently reported to be a critical molecule in T-cell development, however, the precise molecular mechanisms of Tespa1 remain elusive. Here, we demonstrate that Tespa1 shows amino-acid sequence homology to KRAS-induced actin-interacting protein (KRAP), an inositol 1,4,5-trisphosphate receptor (IP3R) binding protein, and that Tespa1 physically associates with IP3R in T and B lymp...
