FYN and Parkinson disease: Studies from our lab have shown that the pro-apoptotic Fyn-mediated signaling cascade contributes to oxidative stress-induced cell death in DAergic neurons (Kaul et al., 2005b; Saminathan et al., 2011) and that Fyn is also a key mediator of neuroinflammatory signaling events contributing to PD’s pathology (Panicker et al., 2015; Panicker et al., 2019).
