New Delhi, Dec 18 || A team of researchers from Bose Institute in Kolkata has developed a peptide therapy that offers a promising, multidisciplinary approach to treating fungal keratitis -- a severe, sight-threatening infection of the cornea -- the clear front part of the eye.
The team, including researchers from the L V Prasad Eye Institute in Hyderabad, designed a 15-residue peptide, named SA-XV, derived from a larger host-defense peptide -- S100A12. This peptide, previously shown to inhibit fungal growth, has been characterised for its antifungal potency and mechanism of action.
Published in the Journal of Biological Chemistry, the researchers hailed the new therapy as an alternative to antimycotics (antifungals) with reduced side effects.
Corneal infections, often referred to as a slow epidemic, affect a significant portion of the population in India, particularly among those with agricultural backgrounds. Overuse and poor hygiene practices related to contact lenses are also a major contributor to corneal infections.
