Acquired tolerance to CBA skin homografts is lost in a large number of C3H mice neonatally injected with CBA spleen cells. The skin homografts persist for at least 2 months but then exhibit a chronic rejection pattern which may last up to 7 months. Histological analysis of the lymphoid tissues reveals the onset of an immune response in the axillary lymph nodes of many 4-month-old tolerant mice....

BACKGROUND Cytomegalovirus (CMV) replication has been associated with more risk for solid organ graft rejection. We wondered whether this association still holds when patients at risk receive prophylactic treatment for CMV. METHODS We correlated CMV infection, biopsy-proven graft rejection, and graft loss in 1,414 patients receiving heart (n=97), kidney (n=917), liver (n=237), or lung (n=163)...

PURPOSE To describe the clinical presentation and management of late (>3.0 years) acute graft rejection in keratolimbal allograft (KLAL) recipients. METHODS This was a multicenter, retrospective observational case series. Six eyes of 6 patients with ocular surface transplant at a mean age of 36.2 years were seen at 3 tertiary referral centers for acute graft rejection between 2007 and 2013. M...

TOPIC Preoperative corneal neovascularization (CNV) is thought to be associated with an increased rate of corneal graft failure and potentially also graft rejection. CLINICAL RELEVANCE New therapeutic options that offer differential influence on the ingrowths or regression of either corneal blood or lymphatic vessels force us to re-evaluate the known data about the role of CNV in keratoplasty...

A large body of evidence suggests that corneal allograft rejection is mediated by a type 1 Th cell response and that deviation toward type 2 immunity favors graft survival. However, clinical observations indicate that patients with severe ocular allergies have increased risk of corneal allograft rejection. We used a mouse model of atopic conjunctivitis to evaluate the effects of Th2 immune devi...

PURPOSE To survey the changes in indications for penetrating keratoplasty (PKP) and re-evaluate the risk factors for allograft rejection and graft failure. METHODS We evaluated the records of 396 eyes of 335 patients who had undergone PKP at the Tokyo University Hospital between 1987 and 1997. Clinical results were analyzed by the Kaplan-Meier life table method and the log-rank test. RESULT...

Early wound excision and grafting of burn wounds is regarded not only as the method of choice in speeding up the healing process in deep burns, but also limits contracture and infection, On the other hand, smoking has generally been implicated in the delay of the healing process in a variety of surgical procedures, In this study we report the outcome of a cross-sectional study of all the 39...

Graft rejection after histocompatibility locus antigen (HLA)-identical stem cell transplantation results from the recognition of minor histocompatibility antigens on donor stem cells by immunocompetent T lymphocytes of recipient origin. T-lymphocyte clones that specifically recognize H-Y epitopes on male target cells have been generated during graft rejection after sex-mismatched transplantatio...
