Low lymphocyte interferon-gamma production and variable proliferative response in anorexia nervosa patients
Interferon-gamma (IFN-γ) production by peripheral blood mononuclear cells (PBMC) in 14 patients with anorexia nervosa (AN) was significantly lower than in 14 age-matched healthy controls. Follow-up samples in four patients displayed low levels, except in two when they recovered the IFN-γ production...
