The aphid BCR4 structure and activity uncover a new defensin peptide superfamily

The paper identifies BCR4, a novel defensin superfamily peptide from aphids, showing insecticidal activity and structural uniqueness.

Intestinal GCN2 controls Drosophila systemic growth in response to Lactiplantibacillus plantarum symbiotic cues encoded by r/tRNA operons

The paper shows that Lactiplantibacillus plantarum uses r/tRNA operons to communicate with Drosophila, activating GCN2 in enterocytes to promote systemic growth.

The non-specific Lipid Transfer Protein (nsLTP) is involved at early and late stages of symbiosis between Alnus glutinosa and Frankia alni.

The paper identifies nsLTP as a gene upregulated in Alnus glutinosa during early symbiosis with Frankia alni, showing its role in nitrogen fixation and localization at root hair and nodule sites.

Zika Virus Infection of Murine and Human Neutrophils and their Function as Trojan Horses to the Placenta

This study shows that neutrophils support ZIKV infection and may facilitate vertical transmission by acting as trojan horses to the placenta.

Metabolic cooperation among commensal bacteria supports Drosophila juvenile growth under nutritional stress

This study identifies a metabolic cooperation between two Drosophila gut bacteria that enhances host growth under nutritional stress by exchanging metabolites.

Commensal bacteria differentially shape the nutritional requirements of Drosophila during juvenile growth

This study shows how two commensal bacteria affect the nutritional needs of Drosophila larvae by providing essential nutrients and compensating for host deficiencies.

A novel role of VisP and Wzz system during O-antigen assembly in Salmonella Typhimurium pathogenesis

This paper identifies VisP as a novel protein involved in O-antigen biosynthesis in Salmonella Typhimurium and shows how O-antigen length affects bacterial pathogenesis.
