Under the genetics program, the BPRC monkey colonies are genetically characterized. The research is focused on the major histocompatibility complex (MHC), which is a polygenic and polymorphic genomic region encoding the cell surface expressed molecules that present antigens to the immune system. At this level susceptibility and resistance to disease as well as the response to vaccines by the adaptive immune system is regulated. Of more recent date is the characterization of killer cell immunoglobulin-like receptors, which are key-regulatory molecules of innate immune functions. The main purpose of the genetics program is thus the definition of the most suitable animals for a specific research line, which will lead to a Refinement and Reduction of the animals used in experiments.
A splice site mutation converts an inhibitory killer cell Ig-like receptor into an activating one.
