TRPV1 has also been implicated in neurodegenerative disorders such as Alzheimer’s disease (Jayant et al., 2016; Balleza-Tapia et al., 2018), Parkinson’s disease (Marinelli et al., 2003; Morgese et al., 2007; Nam et al., 2015; Chung et al., 2017), Huntington’s disease (Lastres-Becker et al., 2003), and glaucomatous optic neuropathy, or glaucoma (Ward et al., 2014; Weitlauf et al., 2014). This evidence concerns the gene TRPV1 and glaucoma.
