Previous implication of neurotrophins in the neurological manifestations of diabetes prompted us to focus on the role of p75NTR neurotrophin receptor (p75NTR) in dopaminergic neurodegeneration under hyperglycemic conditions.<h4>Methods</h4>iPSC-derived dopaminergic neurons, astrocytes and microglia were treated with high glucose (50mM, 100mM) for 48 h to simulate hyperglycemia. Here, BDNF is linked to diabetes mellitus.
