title: Alternative complement pathway: activity levels in allogeneic pregnancy.
abstract: Classical and alternative complement pathway activities have been evaluated in sera of women in progressive stages of gestation and in pregnant mice belonging to outbred or inbred matings, as compared to suitable controls. While classical C pathway was found to be unmodified, the alternative one attained in pregnancy significantly higher activity levels. Results are discussed in the light of mother-conceptus relationships.
