A team of scientists has decoded hidden DNA variations that influence digestion, immune response, and muscle control. The study maps genomic variation across ancestries with a breadth and resolution never before achieved.
Researchers at the University of Pittsburgh have discovered a novel tool to help stratify rejection risk in kidney transplantation. They found that mismatching SIRP-alpha between donors and recipients contributes to worse rejection, scarring, and graft failure in humans, suggesting improved transplant outcomes.
Researchers generated high-quality haplotype-resolved assemblies of the MHC region in five widely used tumor cell lines. The studies identified numerous single nucleotide polymorphisms, indels, and structural variants surrounding HLA class I and II genes, providing valuable resources for cancer immunology research.
A new study by Mass General Brigham researchers has identified a natural 'brake' within the innate immune system that can prevent organ transplant rejection. The discovery highlights a promising target for new therapies and offers hope for longer-lasting transplant success and reduced need for lifelong immunosuppression.
Researchers have identified a subset of T-cells that acts like stem cells and continuously generates effector T-cells that attack transplanted organs. Targeting the transcription factor IRF4 may lead to innovative therapies for patients with chronic infections, cancers, autoimmune diseases and transplanted organs.
Researchers propose a new hypothesis for developing small diameter vascular grafts (SDVG) that heal in a reconstructive manner. They aim to emulate the structure and behavior of living arteries, incorporating a blood vessel network within the graft walls.
Researchers have created a humanized mouse model that can predict the best match for a living organ donor and detect early signs of transplant rejection. The model uses a combination of HLA-G and B regulatory cells to identify patients who may need less immunosuppressive therapy.
Researchers identified a biomarker that predicts kidney transplant rejection risk by analyzing immune molecule ratios. Monitoring this ratio may help clinicians identify high-risk patients and intervene with new treatments to prevent long-term organ rejection.
Researchers showcased Droplet Digital PCR's use in detecting rare mutations, including stem cell integrity and cancer-related de novo mutations. The technology also enabled the non-invasive detection of transplant rejection through cell-free DNA measurement, offering a promising alternative to invasive methods.
Researchers at the University of Pennsylvania have discovered a method to detect organ transplant rejection earlier, using a blood-based approach that targets 'transplant exosomes.' This new strategy may enable doctors to intervene sooner and reduce the risk of long-term side effects from immunosuppressive drugs.
Research from Tufts University reveals that hyperlipidemia, high cholesterol and high triglycerides, accelerates heart-transplant rejection in mice. The studies, published online in the American Journal of Transplantation, found that mice fed a high-fat diet rejected their transplants faster than those on a lower-fat diet.
