Hcn1 receptors ketamine
WebExcept the direct inhibition of ketamine to HCN1 channel (Chen et al., 2009a), Zhang et al. also presented that ketamine reduced activity of presynaptic HCN1 channels might be mediated by presynaptic NMDAR inhibition since ketamine is a noncompetitive ionotropic glutamatergic NMDAR antagonist (Zhang et al., 2016). WebHCN channels consist of four subunits, HCN1–4, that can assemble in various combinations and conformations [56,57]. These channels are expressed in brain, heart, and retina [57]. HCN1 is the common isoform present in hippocampus, neocortex, and cerebellar cortex.

WebAug 30, 2024 · Ketamine is a potent inhibitor of HCN1, and it is possible that inhibition of HCN1 could contribute to or be responsible for the antidepressant- and anxiolytic-like behaviors effects (Chen et al., 2009; Kim et al., 2012). It should be noted that there is a lack of research within utilization of ketamine in PTSD by regulating the HCN1-related ...
