NGFR and ocular cicatricial pemphigoid: In this study, a higher trkANGFR/p75NTR ratio (the outcome of a trkANGFR over-expression) was observed in early OCP-FBs while lower trkANGFR/p75NTR ratio (the outcome of an increased p75NTR expression) was detected in advanced OCP-FBs, according to the clinical and histological features (infiltrates and remodelling features) [2,22,42].
