Role of tumour necrosis factor- (TNF ) in the functional properties of hyalocytes

Abstract

This study indicates that TNFα in vitreous and retina causes activation of hyalocytes, and the activated hyalocytes contribute to the pathogenesis of inflammatory vitreoretinal diseases. Steroid treatment appears to inhibit the activation of hyalocytes in the early stages of the diseases, but might have adverse effects in the late stage through membrane contraction.
