Are genetic loci for Epstein-Barr virus nuclear antigen-1 associated with risk of multiple sclerosis?
Our results suggest that apart from the confirmed HLA region, the association of anti-EBNA-1 IgG titer with MS risk is also mediated through non-HLA genes, and that studies aimed at identifying genetic loci influencing EBNA immune response provides a novel opportunity to identify new and characterize existing genetic risk factors for MS.
These results indicate that chronic signaling through beta(3)-adrenergic receptors during social stress is an adaptive response that improves behavioral function. However, these responses come at the expense of central leptin resistance and melanocortin signaling alterations that contribute to significant and long-lasting metabolic abnormalities.
