B Lymphocyte Development In Galt, Venkata Arunachalam Yeramilli

Dissertations

In rabbits, the primary antibody repertoire is generated in the gut-associated lymphoid tissues (GALT), where bone marrow (BM)-derived B cells undergo a proliferative expansion and somatically diversify the immunoglobulin genes. Unlike in other species, B lymphopoiesis in rabbit arrests a few months after birth, and it is unclear how the peripheral B cell compartment is maintained when there is no influx of newly-made B cells from the BM.

For my dissertation, I investigated how B cells develop in the GALT of rabbits, and how they are maintained in adults after the arrest of lymphopoiesis. To identify cellular signals that promote …
