University of Pittsburgh School of Medicine researchers have developed an early-stage, experimental “living eye drop” that uses naturally occurring eye bacteria to support corneal wound healing. The proof-of-concept study, published in Cell Reports, demonstrates that the harmless eye-dwelling microbe Corynebacterium mastitidis can be genetically modified to secrete an anti-inflammatory therapeutic that promotes healing following corneal injury in a mouse model.
