Infection of mice with live viruses leads to a dramatic increase in the amount of IgG2a Ig with a consequent shift in the ratio of IgG1/IgG2a. To examine the Ig subclass shift induced by viral infection, we challenged mice with live virus, inactivated virus, or replication-defective mutant viruses that were able to infect cells and produce some viral proteins but were not able to complete a replicative cycle. While killed (or inactivated) virus was capable of inducing HSV-specific antibody, it did not stimulate a shift in the subclass of the total Ig. Replication-defective mutant viruses that fail to express a functional ICP8 or ICP27 protein, but not a mutant expressing a defective ICP4 protein, were able to stimulate the shift. Thus, only a portion of the lytic cycle is sufficient to induce the shift. At least part of the effect is mediated by IFN-gamma.
