They found that blocking projections from the insular cortex to the nucleus accumbens, a key brain area … Continued
What are the effects of alcoholism on the immune system? Drs. Crews, Zou and Coleman researched the responses of the neuroimmune system to alcohol.

The National Institute on Alcohol Abuse and Alcoholism has awarded a 5-year K08 Career Development Award to Leon G. Coleman Jr, MD, PhD of the Bowles Center for Alcohol Studies, to study the central and peripheral immune responses to ethanol. Alcohol abuse causes dysfunction of immune responses both in the brain and the periphery. Immune … Continued
