Overcoming cardiac allograft vasculopathy (CAV) by inducing tolerance.
There is compelling evidence that MHC-driven immune processes play a dominant role in the development of cardiac allograft vasculopathy. Thus, it makes intuitive sense that tolerance, which eliminates donor alloreactivity, should protect against CAV. However, in the experimental literature, there are examples of CAV occurring in recipients rendered tolerant by either peripheral or central induc...
متن کاملAllograft Vasculopathy
Ma Cardiac allograft vasculopathy (CAV) remains the Achilles’ heel of long-term survival after heart transplantation. Almost one-third of patients develop CAV by 5 years post-transplant and 1 in 8 deaths beyond a year are due to CAV. Abnormal vascular fibroproliferation in CAV occurs as a result of coronary endothelial inflammation, injury, and dysfunction triggered by immune and nonimmune insu...
متن کاملIL 21 R ( interleukin 21 receptor )
The IL21R gene is comprised of 9 exons (+2 alternative first exons), spanning 48.4kb on chromosome 16p11 (Parrish-Novak, 2000). The human IL21R promoter region, contained within nucleotides -789 to +195 (relative to the start of exon 1a) induces the high levels of transcription in reporter assays (Ueda, 2002). A critical SP1 binding site is contained in the region from -80 to -20 and is essenti...
متن کاملAllograft inflammatory factor-1 expression correlates with cardiac rejection and development of cardiac allograft vasculopathy.
BACKGROUND Standard morphological features of endomyocardial biopsy specimens do not necessarily correlate with the efficacy of immunotherapy or development of cardiac allograft vasculopathy (CAV). We hypothesized that expression of allograft inflammatory factor-1 (AIF-1), a cytokine-inducible, calcium-binding protein associated with vascular smooth muscle cell proliferation, would be associate...
متن کاملDoes Cyclosporine Down Regulate IL-17 in Cardiac Allograft Vasculopathy?
Background: Cardiac allograft vasculopathy (CAV) is characterized by vascular inflammation and intimal proliferation which results in luminal stenosis and myocardial infarction. During vascular inflammation elaboration of several cytokines and differential expression of growth factors have been noted. CAV remains the major threat to long-term graft survival. CD4 and CD8 T-cell subsets play a si...
