Major histocompatibility complex class II-mediated antigen presentation aft
er intranasal infection with murine gammaherpesvirus 68 differs in mediasti
nal lymph nodes and spleen. Evidence that virus-specific CD4(+) T cells wer
e being stimulated was found as late as 6 to 8 months after infection, and
cells specific for the viral gp150(67-83) and ORF11(168-180) peptides were
maintained as a fairly stable proportion of the total response.
