The effect of antigen-specific antibodies on the response of human T-cell lines and clones to rabies virus was studied. Plasmas from rabies-immune vaccine recipients, but not those from nonimmune individuals, enhanced the proliferative response of rabies-reactive T cells to whole inactivated virus or to the purified glycoprotein and nucleocapsid from the rabies virion. Rabies-immune plasma also increased the antigen-induced production of gamma interferon by the rabies-specific T-cell lines. Experiments performed on T-cell clones specific for either rabies glycoprotein or nucleocapsid showed that immune plasma as well as antiglycoprotein and antinucleoprotein murine monoclonal antibodies possessed the capacity to increase significantly the antigen-induced proliferative responses of these clones. The overall results indicate that this in vitro effect of antigen-specific antibodies on the response of regulatory T lymphocytes to rabies virus could be an important factor in the development of effective immune responses in vivo to rabies virus.
