Fig. 1.

Expression profile of host-defence peptides in the eye. The diagram summarises the pattern of expression of the major HDPs in the human eye. These data are derived primarily from studies to detect peptide expression that have been performed on cultured cells in vitro and on tissue/tear fluid samples from human donors (these studies are summarised and references given in the section “Expression and distribution of host-defence peptides in the eye and associated structures”). Lacrimal gland and lacrimal drainage are not included but are discussed in the section “Associated ocular structures”
