The neurotrophins nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) are known to increase upon eye inflammation, promote repair of optic nerve injury, allow corneal tissue and tear film remodeling while retaining functional activity, and finally play a crucial role in the homeostasis of the underneath retina, as reported in both experimental models and ex-vivo human tissues [7,8]. Here, BDNF is linked to eye inflammation.
