Cytotoxic effector cell granules recognized by the monoclonal antibody TIA-1 are present in CD8+ lymphocytes in lymph nodes of human immunodeficiency virus-1-infected patients.

Abstract excerpt

A novel monoclonal antibody (mAB) TIA-1, which recognizes a 15-kd granule-associated protein of cytotoxic T lymphocytes and natural killer cells, has been applied to sections of lymph nodes with human immunodeficiency virus (HIV)-induced lymphadenopathy (follicular hyperplasia and lymphocyte depletion). The protein recognized by this mAB induces apoptosis in permeabilized lymphocytes in vitro. While this mAB...
