Fig 1: Expression of Rbfox1 in glycinergic ACs(A) Rbfox1 is expressed in very few GlyT1-positve ACs (yellow arrows). Rbfox1-positive/GlyT1-negative and GlyT1-positive/Rbfox1-negative cells are pointed with red and green arrows, respectively. (B) Rbfox1 is expressed in sparse population of VGlut3-positve glycinergic ACs (yellow arrows). Red arrows point at Rbfox1-positive cells that not immunostained for GlyT1 (A) or for VGlut3 (B). The boxed areas of the vertical retinal sections are shown at higher magnification.
