bp(GO:"positive regulation of synaptic plasticity")
Pregnenolone sulfate (PREGS) is an endogenous steroid known to ameliorate cognitive performance in animals. PREGS is a modulator of synaptic plasticity, acting on the activation of glutamatergic transmission (Smith et al., 2014) PubMed:25514383
This enhancement of synaptic plasticity and the activation of intracellular pathways are mediated by the activation of alpha7 nAChRs (Dineley et al., 2001; Parri et al., 2011; Plant et al., 2003; Puzzo et al., 2008) PubMed:25514383
It was proposed that the positive action of PREGS is mediated by alpha7 nAChR PubMed:25514383
Through these postsynaptic effects and by influencing neural excitability, nAChRs can modulate or induce synaptic plasticity (Yakel, 2014) PubMed:28445721
Given the indispensable role of NF-κB proteins in synaptic transmission and synaptic plasticity, it is not surprising that NF-κB is plays an indispensable role in cognition and behavior as well PubMed:28745240
In conditional neuronal NF-κB-deficient mice, loss of NF-κB signaling impaired synaptic transmission, spatial memory formation, and plasticity PubMed:25652642
