P75NTR Modulation by LM11A-31 Counteracts Oxidative Stress and Cholesterol Dysmetabolism in a Rotenone-Induced Cell Model of Parkinson's Disease.

ABSTRACT: The p75 neurotrophin receptor (p75NTR) plays a dual role in regulating both pro-survival and pro-apoptotic cascades in various physiological and pathological conditions, including within dopaminergic neuronal population. Notably, its overexpression has been documented in post-mortem Parkinson's disease (PD) brains, where it correlates with a significant downregulation in neuroprotective intracellular mediators. In this study, we aimed at investigating the neuroprotective effects of p75NTR modulation by the small molecule LM11A-31 in a rotenone-induced neuronal model of PD. Differentiated SH-SY5Y cells were treated with 100 nM rotenone, with or without 500 nM LM11A-31. Our results show that LM11A-31 effectively mitigates PD phenotype by enhancing cell viability, reducing apoptosis, mitigati
