Conversion of monoclonal IgG to dimeric and secretory IgA restores neutralizing ability and prevents infection of Omicron lineages

Engineered dimeric and secretory IgA1 neutralized Omicron variants with higher potency than parental IgG.

Helicobacter pylori attachment-blocking antibodies protect against duodenal ulcer disease

The paper shows that antibodies blocking H. pylori attachment reduce chronic inflammation and duodenal ulcer risk by mimicking BabA's binding to ABO glycans.

Immunity to SARS-CoV-2 up to 15 months after infection

This study tracks SARS-CoV-2 immunity in patients up to 15 months post-infection, showing sustained antibody and memory B/T cell responses but reduced neutralization against variants.

Persistence of SARS-CoV-2 specific B- and T-cell responses in convalescent COVID-19 patients 6-8 months after the infection

This study tracks SARS-CoV-2 specific B- and T-cell responses in convalescent patients 6-8 months post-infection, finding sustained memory cell responses despite declining antibody levels.

Human T-bet governs innate and innate-like adaptive IFN-γ immunity against mycobacteria

This study identifies T-bet deficiency as a cause of mycobacterial disease by impairing IFN-γ production in innate and innate-like adaptive lymphocytes.
