PRKCD and epilepsy: Fyn phosphorylates protein kinase C delta (PKCδ) which leads to the translocation of nuclear factor-kappa (NFκB) to the nucleus and transcription of key proinflammatory cytokine genes and the production of reactive oxygen species in both PD and epilepsy models (Panicker et al., 2015, 2019; Sharma et al., 2018, 2021).
