Transforming growth factor beta in Alzheimer's disease.

Chao, C C, Hu, S, Frey, W H, Ala, T A, Tourtellotte, W W, Peterson, P K

Alzheimer's disease (AD) has been hypothesized to be an inflammatory condition. We hypothesized that anti-inflammatory cytokines, such as transforming growth factor beta (TGF-beta), counteract the...
