Influence of macrophages on HSV-1 induced IL 2 production by human lymphocytes
Previous work has demonstrated that human peripheral blood mononuclear cells (PBMC) from HSV-1 seropositive individuals produce interleukin 2 (IL 2) following stimulation in vitro with uv-inactivated herpes simplex virus type 1 (HSV antigen). This study investigated the accessory macrophage (MO) and monokine requirements for IL 2 production by enriched T lymphocytes from HSV-1 seropositive individuals. Following removal of accessory MO populations, enriched T lymphocytes did not secrete IL 2 in response to HSV antigen. However, IL 2 production was restored by the addition of autologous, ..gamma..-irradiated (5000R) MO. HSV antigen-pulsed MO also induced IL 2 production by enriched T lymphocytes. Furthermore, when HSV-pulsed macrophages were treated with paraformaldehyde they no longer caused T lymphocytes to produce IL 2 unless exogenous monokines were provided. Neither exogenous monokines nor purified human IL 1 could support HSV antigen induced IL 2 production in the absence of MO. These studies demonstrated that MO are required for HSV-induced IL 2 production by T lymphocytes from HSV-1 seropositive individuals. Furthermore, these MO appear to provide two functions required for IL 2 production: viral antigen display and monokine production.
