Obesity , Leptin & Risk of Autoimmunity: a Problem in Achieving Herd Immunity

Scientists find lean subjects made protective antibodies after infection while obese subjects did not make protective antibodies—they made maladaptive autoantibodies instead. Researchers speculate that leptin plays a role in skewing the immune response toward autoimmunity after infection. Here's the details!
