Galectin-1 reduces the severity of herpes simplex virus-induced ocular immunopathological lesions.

ABSTRACT: Stromal keratitis is a chronic immunopathological lesion of the eye caused by HSV-1 infection that can result in blindness. Because the inflammatory lesions are primarily orchestrated by Th1 cells, and to a lesser extent by Th17 cells, inhibiting their activity represents a useful form of therapy. In this study we evaluated the therapeutic potential of galectin-1 (gal-1), an endogenous lectin that in some autoimmune diseases was shown to suppress the functions of Th1 and Th17 cells. Treatment was begun at different times after ocular infection with HSV and the outcome was assessed clinically as well as for effects on various immune parameters. Treatment with recombinant gal-1 significantly diminished stromal keratitis lesion severity and the extent of corneal neovascularization. Treated mi
