title: The effects of stress on the development of immunological memory following low-dose antigen priming in mice.
abstract: Observable stress effects on immune responses may be a function of the quantitative and qualitative characteristics of the stressor, and the outcome measurement of immunity. Further, the effects of stress on humoral immunity, in particular, may be sensitive to the concentrations of antigen used to elicit a response. We have studied the effects of footshock stress during the time of priming with low concentrations of antigen on the secondary response to another low dose of antigen. The secondary humoral immune response of C3H/HeJ mice to the protein antigen keyhole limpet hemocyanin was examined following footshock, exposure to the apparatus without shock, or exposure to the home cage. Footshock reproducibly depressed the IgG anti-KLH response, and the effect on the IgM response was sporadic. Initially, footshock was administered for 7 days before and 7 days after priming with low amounts of antigen. Subsequent studies demonstrated that a single footshock session delivered 24 h after priming could suppress the IgG anti-KLH response.
