Abstract

Purpose : To examine the effect of tropomyosin receptor kinase B (TrkB) receptor removal on basal retinal ganglion cell (RGC) function and recovery from acute intraocular pressure (IOP) stress following conditional deletion of neuronal-specific TrkB receptors in adult mice. Methods : Conditional TrkB receptor knockout (KO) from Thy-1 positive neurons was induced via daily tamoxifen injections (100 ul i.p. 75mg/kg, 5 days) in 3-month old Thy1-GFP CreERT2+/- TrkBfl/fl transgenic (TrkB KO n=12) and control CreERT2-/- TrkBfl/fl mice (n=12). Four weeks later, one eye was exposed to controlled IOP stress of 50mmHg for 30 minutes, achieved via anterior chamber cannulation (50 μm glass micropipette..
