Abstract

Solenocytes taken from mice inoculated with coxsackievirus B3 (CVB3) (Nancy) developed an in vitro proliferative response against CVB3 antigen. This response could not be detected earlier than 8 days postinoculation but could be detected up to 28 days after exposure to CB3. CVB3-sensitized splenocytes responded not only to the CVB3 antigen but to other enteroviruses as well. This response was found to be enterovirus specific in that no response was detected to a non-enteroviral picornavirus, encephalomyocarditis virus, or to an unrelated influenza virus. The generation of a splenocyte population capable of responding to an enterovirus group antigen(s) was not limited to inoculation of mice with CVB3, as similar responses were generated when mice were inoculated with CVB2. Cell subset depletions revealed that the major cell type responding to the enterovirus group antigen(s) was the CD4+ T cell. Current evidence suggests that the group antigen(s) resides in the structural proteins of the virus, since spleen cells from mice inoculated with a UV-inactivated, highly purified preparation of CVB3 virions also responded in vitro against enteroviral antigens.
