Beneficial but limited effect of added pooled human IgG to GWI serum in reducing apoptosis. The limited effect is presumably due to the expected lack of antibodies in IgG of rare diseases (anthrax, botulism, plague, rabies, etc.) to which the general population is not typically exposed and for which no vaccines are given routinely. Bars are SEM. From Rouse and Kaistha. 63
