Why Bad Immunity Genes Survive
University of Utah biologists found new evidence why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs - even though some of those genes make us susceptible to infections and to autoimmune diseases. Major histocompatibility complex (MHC) proteins are found on the surface of most cells in vertebrate animals.
