Small lymphocytes in peripheral lymphoid tissues of nude mice. Life-span and distribution.

The distribution of small lymphocytes according to life-span in the peripheral lymphoid tissues of the mouse mutant "nude" has been studied by means of auto-radiography and scintillation counting to evaluate the localization of B lymphocytes with varying life-span. The vast majority of the lymphocytes in this congenitally athymic mouse are relatively long-lived, although few cells live for 6 weeks or more. Differences in labelling percentages of blood, spleen and lymph node lymphocytes indicated a production of lymphocytes with a short residence time in the spleen. A similar production was not seen in the lymph nodes. While the lymphocytes in the spleen were evenly distributed according to life-span, the paracortical lymphocytes in lymph nodes were found to have a generally shorter life-span than those of the cortex, in opposition to findings in normal mice. The cortical cells which were by far the most numerous in the lymph nodes seemed to be more sessile than para-cortical lymphocytes. The life-span of these latter cells are comparable to those of thoracic duct lymphocytes, and the scarcity of cells in the paracortex reflects the small number of recirculating lymphocytes in nude mice.[1]
