IL33 and diabetes mellitus: Using streptozotocin (STZ)-induced diabetes in wild-type C57BL/6J (WT) and Il33 knockout (Il33−/−) mice, retinal inflammation, micro- and macro-glial activation, electrophysiological function, retinal thinning, neuronal loss, and development of acellular capillaries were assessed, with parallel analysis of cell-specific molecular pathways in vivo and in vitro.
