a(CHEBI:"amyloid-beta polypeptide 42") increases path(HBP:neurotoxicity)
As with nicotine, the weak alpha7 nAChR agonist GTS-21 is neuroprotective, specifically protecting against Abeta1–42-elicited neurotoxicity154. This effect is probably due to small, protracted increases in receptor-mediated Ca2+ influx. importantly, high concentrations of GTS-21 reduced cell survival, underlining the possible risk of over-stimulation152
