Irradiation Prolongs Survival of Alport Mice

Irradiation prolongs survival of Alport mice.

Alport syndrome is a hereditary nephropathy that results in irreversible, progressive renal failure. Recent reports suggested that bone marrow transplantation (BMT) has a beneficial, short-term effect on renal injury in Alport (Col4a3(-/-)) mice, but its long-term effects, especially with regard to survival, are unknown. In this study, Alport mice received a transplant of either wild-type or Co...

Mimotope Prolongs the Survival of Mice A Cryptococcal Capsular Polysaccharide

Alpha1-antitrypsin monotherapy prolongs islet allograft survival in mice.

Islet transplantation for type 1 diabetic patients shows promising results with the use of nondiabetogenic immunosuppressive therapy. However, in addition to compromising the immune system of transplant recipients, long-term studies demonstrate that islet viability is impaired. Here, we demonstrate that, in the absence of immunosuppressive agents, monotherapy with clinical-grade human alpha1-an...

Deficiency of C5aR prolongs renal allograft survival.

Interaction between C5a, a product of complement activation, and its receptor (C5aR) upregulates antigen-specific T cell responses by modulating the activation of antigen-presenting cells and T cells. Whether this C5a-C5aR interaction contributes to the immune responses that promote renal allograft rejection is unknown. Here, we found that deficiency of C5aR in both graft and recipient reduced ...

Rapid Publication Encapsulation of Rat Islets of Langerhans Prolongs Xenog raft Survival in Diabetic Mice

Rat islets encapsulated in alginate-polylysine membranes were implanted intraperitoneally into nonimmunosuppressed streptozocin-induced diabetic mice. Diabetes was reversed within 3 days, and the animals remained normoglycemic for up to 144 days, with a mean xenograft survival of 80 days. This was significantly greater than nonencapsulated islets, which functioned for <14 days. The graft surviv...
