Immune exhaustion during chronic infections in cattle
Recently, dysfunction of antigen-specific T cells is well documented as T-cell exhaustion and has been defined by the loss of effector functions during chronic infections and cancer in human. The exhausted T cells are characterized phenotypically by the surface expression of immunoinhibitory receptors, such as programmed death 1 (PD-1), lymphocyte activation gene 3 (LAG-3), T-cell immunoglobuli...
متن کاملResisting Immune Exhaustion in HIV-1 Infection
Research in Translation T he human immune system is extraordinarily active against infection with HIV-1, yet never eliminates the virus and rarely controls viral replication for prolonged periods without the assistance of anti-retroviral therapy (ART). In order to harness the power of the human immune response in HIV therapy, we need a better understanding of the key elements of protective immu...
متن کاملBone transplantation and immune response
Bone is the second most common transplant tissue after blood, with the iliac crest autologous graft being most used. Bone transplantation induces osteogenesis to repair bone defects. Despite being the most efficient, autogenous bone requires an additional incision and its supply may be inadequate. Deepfrozen allogeneic bone can be an alternative, but is at risk of microbiological contamination,...
متن کاملOcular Immune Privilege and Transplantation
Allografts are afforded a level of protection from rejection within immune-privileged tissues. Immune-privileged tissues involve mechanisms that suppress inflammation and promote immune tolerance. There are anatomical features, soluble factors, membrane-associated proteins, and alternative antigen-presenting cells (APC) that contribute to allograft survival in the immune-privileged tissue. This...
متن کاملPrediction of Rejection in Renal Transplantation by Immune Parameters
Background: Monitoring of phenotypic characteristics of T-lymphocytes in peripheral blood is commonly performed to give the clinical parameters in the management of kidney transplant recipients. Objective: To predict rejection in renal transplantation by immune parameters. Methods: 16 non-diabetic kidney transplant candidates (4 females and 12 males, age = 20-65 yr, first time transplant) wer...
