Objective: The interleukin-6 (IL-6) family of cytokines is associated with retinal ganglion cell (RGC) survival and glial reactivity in glaucoma. The purpose of this study was to evaluate glaucoma-related changes in glycoprotein-130 (gp130), the common signal transducer of the IL-6 family of cytokines, as they relate to RGC health, glial reactivity and expression of IL-6 cytokine family members.Methods: For all experiments, we examined healthy retina (young C57), aged retina (aged C57), retina predisposed to glaucoma (young DBA/2) and retina with IOP-induced glaucoma (aged DBA/2). We determined retinal gene expression of gp130 and IL-6 family members, using quantitative PCR, and protein expression of gp130, using multiplex ELISA. For protein localization and cell-specific expression, we performed co-immunolabeling for gp130 and cell type -specif.. View More»
