The presence of peptidergic and noradrenergic sympathetic nerve fibers in specific compartments of both primary and secondary lymphoid organs of the rodent is well established. These nerve fibers directly contact lymphocytes and macrophages, as well as vascular and trabecular smooth muscle. We

In an effort to gain knowledge on immune functions in beluga whales, Delphinapterus leucas, we have used two physical methods for the purification of T lymphocytes of spleen cells. Isolation by sheep red blood cells (SRBC) rosetting and by adherence on nylon wool columns were tested. SRBC-rosetting
