Figure 2: Constitutive expression of gp130 localizes primarily to the inner retina in healthy retina. Representative fluorescent micrographs of gp130 immunolabeling (green) with DAPI counterstain (blue) in paraffin sections of whole eye from C57 retina reveals the presence of gp130 in the OPL, INL, IPL, GCL and NFL. RPE: Retina pigment epithelium; ONL: Outer nuclear layer; OPL: Outer plexiform layer; INL: Inner nuclear layer; IPL: Inner plexiform layer; GCL: Ganglion cell layer; NFL: Nerve fiber layer
