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(H2b)-->C3H(H2k) 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 (H2k)--> C3H combination with disparity at only non-MHC-HA loci. Postoperative intraperitoneal administration of IL-10 (100 microg/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 microg/d, i.p., 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.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000920 Antibody-Dependent Cell Cytotoxicity The phenomenon of antibody-mediated target cell destruction by non-sensitized effector cells. The identity of the target cell varies, but it must possess surface IMMUNOGLOBULIN G whose Fc portion is intact. The effector cell is a "killer" cell possessing Fc receptors. It may be a lymphocyte lacking conventional B- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent.
