CCL2 and ocular melanoma: Concerning the protein release of cytokines and chemokines, we did not observe any significant variations in the release by S. aureus-infected HPBCs compared to the non-infected counterparts whereas the upregulation of IL-6, CCL2, CXCL1, CXCL8, and OPG release occurred with LPS stimulation in both SM- and OM-HPBCs.
