... B7-H3 preferentially regulates CD4independent induction of CD8 CTL responses. B7-H3 action through T cell costimulation is also implied by the fact that rapamycin treatment induced permanent cardiac and islet allograft survival in B7-H3 knockout mice (17), indicating that B7-H3 functions to promote ...

Lymphopoiesis
Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cell (WBC). It is more formally known as lymphoid hematopoiesis.Pathosis in lymphopoiesis leads to any of various lymphoproliferative disorders, such as the lymphomas and lymphoid leukemias.
