We then examined the gene expression of several proinflammatory cytokines (TNFα, IL-1β, IL-6, and IL-18) (Fig. 6b) and chemokines (MIP-1α, MIP-1β, MIP-2, MCPI, and IP10) (Fig. 6c) that have been implicated in human and experimental models of glaucoma [43, 48, 59–61]. Here, IL18 is linked to glaucoma.
