TL;DR: This study provides detailed insights into the systemic immune response to SARS-CoV-2 infection and it reveals profound alterations in the myeloid cell compartment associated with severe COVID-19.
Journal ArticleDOI

TL;DR: In this article, the authors conducted a cohort study with two age groups, young vaccinees below the age of 60 and elderly vaccinees over 80, to compare their antibody responses to the first and second dose of the BNT162b2 COVID-19 vaccination.
Journal ArticleDOI

TL;DR: Imaging neurons of organoids reveal that SARS‐CoV‐2 exposure is associated with altered distribution of Tau from axons to soma, hyperphosphorylation, and apparent neuronal death, and these studies provide initial insights into the potential neurotoxic effect of Sars‐Cov‐2.
Journal ArticleDOI
