Tracking antigen specific T cell dynamics in vivo
... In our quantitative model, the maintenance of self-tolerance is dependent on the ratio of TR cells to potentially pathogenic autoreactive T (TPATH) cells that respond to a given peripheral antigen. In a given lymph node, this ratio will be dynamic and fluctuate depending on the infectious status of ...

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.
