Abstract:The SARS-CoV-2 spike protein and prions use common pathogenic pathways
to induce toxicity in neurons. Infectious prions activate the p38
mitogen activated protein kinase (MAPK) pathway, and SARS-CoV-2 spike
proteins induce the p38 MAPK and c-Jun NH2-terminal kinase (JNK)
pathways through toll-like receptor signaling, indicating the potential
for similar neurotoxicity, causing prion and prion-like disease. In this
review we analyze the roles of autophagy inhibition, elevated
intracellular p53 levels and reduced… Show more
“…Complexes involving more than one amyloid-forming compound may play a role in vivo leading to toxic fibril forms (Young et al, 2015) and this raises the possibility that copolymers involving SARS-CoV-2 spike protein amyloid and Aß (Idrees and Kumar, 2021) could play a role in triggering AD-like pathology. The SARS-CoV-2 spike protein is itself neurotoxic and activates Aß expression (Kyriakopoulos et al, 2022) providing a clear link between these two amyloid-forming proteins and neurotoxicity.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
