This study shows that the lack of ancestral SARS-CoV-2 immune imprinting in children makes them more susceptible to BA.3.2.2 infection, as it evades neutralizing antibodies typically present in adults.

The paper engineers a probiotic Escherichia coli to degrade nicotine in the gut, reducing NASH in mice by improving liver function and blocking the gut-liver axis.

This study shows that V(D)J-humanized mice can replicate severe SARS-CoV-2 immune imprinting in humans, revealing that pre-existing antibody abundance influences imprinting severity.
