Increased phosphorylated tau (pTau-181) is associated with neurological post-acute sequelae of coronavirus disease in essential workers: a prospective cohort study before and after COVID-19 onset

Increased phosphorylated tau (pTau-181) is associated with neurological post-acute sequelae of coronavirus disease in essential workers: a prospective cohort study before and after COVID-19 onset

New longitudinal data from essential workers suggests a neurological Long COVID subtype is associated with a marked rise in plasma pTau-181 (a biomarker often used in Alzheimer’s disease research) compared with pre-infection baseline.

Virus-induced endothelial senescence as a cause and driving factor for ME/CFS and long COVID: mediated by a dysfunctional immune system

Virus-induced endothelial senescence as a cause and driving factor for ME/CFS and long COVID: mediated by a dysfunctional immune system

A new theory suggests some viral infections may push blood vessel cells into a long-term stress state, offering a possible explanation for the lasting symptoms seen in ME/CFS and Long COVID.
