Abstract

The migration of B and T lymphocytes in the mouse has been studied by using 1) short-term in vivo homing studies, and 2) an in vitro assay of lymphocyte binding to specialized lymphoid organ venules (post-capillary, high endothelial venules (HEV)) in frozen sections of lymph nodes and Peyer's patches. The homing characteristics of B and T cell populations are largely independent of their organ of origin. B cells from any source distribute preferentially to Peyer's patches, whereas T cells home preferentially to peripheral lymph nodes. This organ specificity of migration appears to be determined at the site of lymphocyte exit from the blood by selective recognition of organ-specific determinants on the endothelial cells of HEV. In addition, the in vivo tendency of B cells to migrate preferentially to the spleen, and of T cells to localize better in lymph nodes is confirmed. The results indicate that, in a hypothetical situation in which an equal number of B and T lymphocytes localized in peripheral lymph nodes (or bound in vitro to peripheral node HEV), there would be about 2.5 B cells for every T cell in the mesenteric node, four to six B cells per T cell in Peyer's patches, and seven to nine B cells per T cell in the spleen.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
