... regulates T cell function. Although B7-1 and B7-2 can bind both CD28 and CTLA-4 via the same MYPPPY motif, the affinity of CTLA-4 for these ligands is much higher compared to that of CD28. Clearly, expression kinetics, location, and binding affinity are diverse among the ligands and receptors in thi ...

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.
