Abstract.

Objective:

To identify the differences in cytokine profile between allogeneic and syngeneic pregnancy in mice with collagen-induced arthritis (CIA).

Methods:

Mice (strain B10.RIII) were injected with bovine collagen. Females were mated with males of the same strain (syngeneic pregnancy) or with males of strain B10. Q (allogeneic pregnancy). Concentrations of cytokines were measured during pregnancy and after delivery, and the onset and evolution of arthritis was followed in all female animals throughout the study period.

Results:

In female mice that developed CIA, cytokine concentrations were lower in allogeneic pregnancies than syngeneic pregnancies. When paired cytokine concentrations were compared in each animal during and after pregnancy, MCP-1 was lower during gestation than after delivery in both groups of pregnant mice, IL-6 was lower during gestation than after delivery only in allogeneic pregnancies, and IL-10 was lower during gestation than after delivery in allogeneic pregnancies, whereas in syngeneic pregnancies IL-10 was higher during gestation than after delivery.

Conclusions:

Allogeneic pregnancy was associated with less arthritis because of lower concentrations of proinflammatory cytokines (IL-6 and others), not because of an increase in the concentration of antiinflammatory cytokines (IL-10).
