| Abstract: | Several in vitro T cell clones were markedly deficient in their ability to home to peripheral lymphoid tissue. This was found for an alloreactive noncytolytic clone, a soluble antigen- (KLH)specific line, and cytotoxic clones specific for allogeneic cells and for Abelson virus-induced lymphoma cells. This abnormal circulation pattern was probably caused by the lack of the receptors of the lymphocytes for high endothelial venules (HEV), as implied by the lack of binding of these T cells to HEV in frozen sections of mouse lymph node and Peyer's patches. The loss of surface receptors that are necessary for normal lymphocyte migration may thereby alter the in vivo function of adoptively transferred T cells. |
