Abstract
A study was performed using monoclonal antibodies and the immunoperoxidase technic to identify T-cells and T-subsets in human tonsil sections. The in situ topographic identification of T-cells, helper cells, and suppressor cells was achieved. This model may therefore be applied to other normal lymphoid tissues. Its potential pathologic importance lies in the fact that certain disorders may be associated with depletion of lymphocyte subsets from their normal areas of “homing,” and that lymphoma cells may mirror their putative normal counterparts in their selective metastatic migration pattern. The improved knowledge of normal lymphocyte subset micrpenvironment afforded by this technic may therefore be of value in applied pathology.
