Figure 2. TrkA^NGFR/p75^NTR protein expression in primary untouched VKC conjunctival epithelial cells (VKC-ECs). Confocal analysis specific for trkA^NGFR (middle) and p75^NTR (right) in VKC-ECs. Control-isotype signal (left) was used in channel series acquisitions, and identical acquisition settings were applied for all images (60× oil immersion).
