the first site of SARS-CoV-2 infection is the conducting airways1,2,3. These sections of the airway are lined with a pseudostratified epithelium blanketed in mucus, which is produced by goblet and other secretory cells. The mucus acts as a barrier between...

Briefly, after the final wash the beads were washed once with exchange buffer (50 mM Tris-HCl PH 7.5, 100 mM NaCl). Bead-bound proteins were alkylated with 3 mM iodoacetamide in the dark for 45 min and then quenched with 3 mM DTT for 15 min. Digestion was performed ...
The results revealed that, while the covalent Mpro adduct with nirmatrelvir (1) slowly exchanges with 28 over time reaching ∼20% exchange 4 h post incubation (Figure 5b,c), the covalent Mpro adduct with 13 did not exchange with 28, even after prolonged incubation (>48 h). Thus, ...

The spread of COVID-19 has taken a toll on many countries and its healthcare system over the last two years. Governments have sought to mitigate the repercussions of the pandemic by implementing aggressive top-down control measures and introducing immens
Despite low rates of bacterial co-infections reported in the molecular studies of COVID-19 patients, high rates of antimicrobial prescriptions were reported. For example, in a study in China, 101 patients (99%) from critical and non-critical care, received antibacterial therapy7. No bacterial co...

In late 2022, SARS-CoV-2 Omicron subvariants have become highly diversified, and XBB is spreading rapidly around the world. Our phylogenetic analyses suggested that XBB emerged through the recombination of two cocirculating BA.2 lineages, BJ.1 and BM.1.1.1 (a progeny of BA.2.75), during th...
