MAPT and COVID-19: found that neurodegenerative proteins such as, for example, Aβ, neurofilament light, neural granule proteins, total tau, and p‐T181‐tau were significantly increased in neuronal EV in almost all participants recovering from COVID‐19 for one month to three months.[97] Although it is unknown whether such protein markers of neuronal dysfunction in EV are long‐lasting, these could all be potential plasma biomarkers of neuroinflammation or neuronal damage following COVID‐19.
