Interestingly, we found that both pTau and total tau showed nonsignificant change in patients died during acute COVID‐19 compared with individuals without SARS‐COV‐2 infection, but pTau was unexpectedly upregulated in the group clinically recovered from COVID‐19, especially at AD‐related epitopes like Thr181, Thr217 and AT8 (Figure 1a–c, Figure S1). Here, MAPT is linked to COVID-19.
