Cellular interleukin-10 (cIL-10) has been shown to inhibit cytokine production by T helper type 1 (Th1) cells by blocking antigen presenting cell function. This activity has suggested that IL-10 might be useful in the treatment of transplant rejection. Stimulatory effects of IL-10 however, have also been observed both on T and B cell differentiation. In this study, we examined the influence of recombinant (r) mouse (m) IL-10 on heterotopic vascularized heart allograft survival in the B10 (H2 b)→ C3H (H2 k) strain combination that crosses both major histocompatibility complex (MHC) and non-MHC-histocompatibility antigen (non-MHC-HA) barriers. The influence of IL-10 was also examined in the B10. BR (H2 k)→ C3H combination with disparity at only non-MHC-HA loci. Postoperative intraperitoneal administration of IL-10 (100 μg/d, days 0-6) significantly accelerated heart graft rejection both in the B10→ C3H (mean survival time [MST] 7.8±0.2 days; control MST 10.6±0.6 days; P< 0.05) and the B10. BR→ C3H combination (MST 14.3±0.5 days; control MST 77.7±14.4 days). Ex vivo IL-10 perfusion of donor hearts for either 15 min or 2 hr did not affect subsequent graft survival. Immunologic monitoring of transplanted mice revealed that IL-10 treatment (100 μg/d, ip, days 0-6) increased both the circulating complement-dependent cytotoxic (CDC) antibody titer and splenic anti-donor cytotoxic T lymphocyte (CTL) activity measured up to 3 weeks posttransplant. These findings indicate that post transplant systemic administration of cIL-10 can promote vascularized allograft rejection, and that this may reflect stimulation both of B and T cell alloimmune responses.
