Sequential class switching generates antigen-specific gut IgA from IgG1 B cells. Immunity 2025, 58: 3075-3093.e6. PMID: 41253159, PMCID: PMC12834128, DOI: 10.1016/j.immuni.2025.10.022.Peer-Reviewed Original ResearchThis study investigates how gut-specific IgA antibodies are generated from IgG1 B cells through sequential class switching, highlighting a crucial mechanism for designing effective mucosal vaccines.Cysteinyl leukotrienes stimulate gut absorption of food allergens to promote anaphylaxis in mice
