THIK-1 (KCNK13) is a halothane-inhibited and anionic-lipid-activated two-pore domain (K2P) K+ channel implicated in microglial activation and neuroinflammation, and a current target for the treatment of neurodegenerative disorders, for example Alzheimer’s disease and amyothropic lateral sclerosis (ALS). The gene discussed is KCNK13; the disease is amyotrophic lateral sclerosis.
