The effect of exposure of female DBA/1 mice to collagen II (CII) prior to breeding on the susceptibility of their offspring to CII-induced arthritis (CIA) was investigated. It was found that female offspring, born within 3 months after exposure of the mothers to CII, had a significantly reduced incidence of CIA, following immunization with CII. Just prior to this immunization, no anti-CII could be detected in the offspring. Offspring born more than 3 months after exposure of the mothers to CII showed no differences in susceptibility to induction of CIA, if optimal conditions for induction were used. However, when suboptimal conditions for induction of CIA were used, offspring of females that had been exposed to CII developed less severe arthritis and had a delayed onset of arthritis as compared with controls. It is concluded that exposure of female mice to CII prior to mating results in changes in the immune response to CII in the offspring, leading to a subtle decrease in susceptibility to CIA.
