- (RSS) (BioRxiv All) Ant abaecin-2 is a context-dependent copper-binding effector that can be either inhibitory or protective: Host defense peptides (HDPs) are important components of the innate immune system that are used to combat pathogens and often rely on metal binding for their function. However, controlling trace nutrients such as transition metals may have other roles in host-symbiont interactions beyond poisoning harmful pathogens. This… https://www.biorxiv.org/content/10.64898/2026.04.18.719391v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
- (RSS) (BioRxiv All) Structural and chemical properties of insects' chitin-containing extracellular matrices: Insects' body barriers rely on specialized extracellular matrices that protect against harmful environmental influences. The outer barrier is the cuticle, which is composed of chitin, cuticle proteins and lipids. The peritrophic matrix (PM) serves as an inner barrier lining the midgut epithelium. It is composed of chitin fibers that are… https://www.biorxiv.org/content/10.64898/2026.04.18.718486v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
- (RSS) (BioRxiv All) Cellular remodeling during photosymbiosis establishment revealed by single-cell dual proteomics: Endosymbiosis of phytoplankton in heterotrophic hosts is ecologically important and has led to key evolutionary innovations. However, the dynamic molecular processes underlying endosymbiosis establishment remain poorly understood. Here, using large-particle sorting and liquid chromatography-tandem mass spectrometry, we unravel… https://www.biorxiv.org/content/10.64898/2026.04.21.719821v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
