Identification of HLA-A2-restricted immunogenic peptides derived from a xenogenic porcine major histocompatibility complex.

abstract：:The use of xenogeneic porcine pancreatic islets has been shown to be a potentially promising alternative to using human allogeneic islets to treat insulin-dependent type 1 diabetes (T1D). This article provides an overview of the existing FDA regulatory framework that would be applied to the regulation of clinical tria...
