Relative quantification of human β‑defensins gene expression in pterygium and normal conjunctiva samples.

The human ocular surface produces highly conserved cationic peptides. Human β‑defensins (HBDs) serve an important role in innate and adaptive immunity. They are primarily expressed in epithelial cells in response to infection and provide the first line of defence against invading microbes.
