Although many of the cytokines and chemokines that we have measured in our assays are not frequently associated with KC responses, they have been shown to be secreted by KCs and/or macrophages in previous studies, i.e. RANTES, EPO, IL-5, VEGF, and M-CSF [33,37,38,39,40,41]. The gene discussed is CCL5; the disease is dry eye syndrome.
