High temperature treatment optimized for symbiont suppression in an obligatory gut bacterial symbiosis in the stinkbug Plautia stali

This study investigates the effect of high temperature on symbiont suppression in the stinkbug Plautia stali, finding that 37°C treatment effectively reduces symbiont titers with minimal host damage.

Defensive fungal symbiosis on insect hindlegs

The paper identifies a novel defensive fungal symbiosis in stinkbugs where females transfer fungi to eggs to protect them from wasp parasitism.

Mechanisms underpinning morphogenesis of symbiotic organ specialized for hosting indispensable microbial symbiont in stinkbug

The paper investigates the morphogenesis of a symbiotic organ in stinkbugs, showing that muscle fiber arrangement and epithelial cell proliferation drive crypt formation, which occurs autonomously even in the absence of symbionts.

SARS-CoV-2 Omicron subvariants evolved to promote further escape from MHC-I recognition

This study shows that SARS-CoV-2 Omicron subvariants are better at suppressing MHC-I expression than earlier variants, aiding their evasion from CD8+ T cell immunity.

Single mutation makes Escherichia coli an insect mutualist

The paper shows that a single mutation in E. coli enables it to become an insect mutualist by disrupting carbon catabolite repression.

Disruption of nasal bacteria enhances protective immune responses to influenza A virus and SARS-CoV-2 infection in mice

This study shows that disrupting nasal bacteria in mice enhances antibody responses to intranasal influenza and SARS-CoV-2 vaccines, highlighting a role for nasal microbiota in immune induction.

The expansion in lymphoid organs of IL-4+ BATF+ T follicular helper cells is linked to IgG4 class switching in vivo

The paper identifies IL-4+ BATF+ T follicular helper cells in IgG4-related disease that correlate with IgG4 class switching in lymphoid organs.
