Cytotoxic CD8 T cells exert their antiviral and antitumor activity primarily through the secretion of cytotoxic granules. Degranulation activity and cytotoxic granules (perforin plus granzymes) generally define CD8 T cells with cytotoxic function. In this study, we have investigated the expression of granzyme K (GrmK) in comparison to that of GrmA, GrmB, and perforin. The expression of the cyto...
Cytotoxic T cells were detected in the cervical lymph nodes, lungs, spleen, and peripheral blood of mice with influenza. Lymphocytes decreased in the peripheral circulation and increased in the lung during the period of acute inflammation and pneumonia. Peak cytotoxic T-cell activity was present at the time of marked pulmonary infiltration, and it decreased with resolution of the pneumonia. The...
Thirty-two natural killer (NK) and cytotoxic T-cell lymphomas and 14 noncytotoxic nodal T-cell lymphoma controls were immunostained with the use of monoclonal antibodies reactive against NK-cell receptor (NKR) molecules (CD94, NKG2A, p58.2, p58.1, p140, p70, p50.3). All NK-cell lymphomas (4 nasal/oral and 1 intestinal) expressed at least 1 NKR, the CD94/NKG2A complex. Two were positive for 1 or...
