Based in Southern California, Stephanie Zargar is an office manager with Cal-Am Properties and manages a full range of operational activities. One area in which Stephanie Zargar has a strong personal interest is multiple sclerosis research, which addresses a disease that reflects complex interactions between environmental and genetic factors.
Recent research at the University Hospital Zurich focuses on HLA-DR15, a gene variant that carries 60 percent of the genetic risk of the disease. The study reveals the mechanism by which immune cells of those with HLA-DR15 genetic variants are primed to recognize microbes like the Epstein-Barr virus effectively. Unfortunately, this can lead to an immune reaction occurring against the individual’s own brain tissue.
The reaction centers on the T lymphocytes, which are tasked with modulating the immune response and distinguishing between the body's own tissue and foreign proteins. Through a process of cross-reactivity, they can erroneously attack proteins in the brain. The researchers are working to understand the exact mechanism through which this occurs, which may ultimately lead to addressing a number of autoimmune conditions.
