Human T lymphocytes activated with PHA express Ia-like antigens and acquire the ability to
stimulate autologous T lymphocytes in mixed lymphocyte reaction. This reaction is
immunological in nature since it has specificity and memory. Ia-like antigens play a role in
the stimulation of T lymphocytes by autologous PHA-T lymphocytes since monoclonal
antibodies to Ia-like antigens can significantly, although not completely, inhibit the
stimulation.

This reaction is immunological in nature since it has specificity and memory. Ia-like antigens play a role in the stimulation of T lymphocytes by autologous PHA-T lymphocytes since monoclonal antibodies to Ia-like antigens can significantly, although not completely, inhibit the stimulation.
