Development of mouse thymocytes through the pre-TCR checkpoint requires WNK1 kinase signalling via the OXSR1 and STK39 kinases and the SLC12A2 ion co-transporter leading to MYC-dependent cell proliferation.
Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.
Arp2/3 complex-mediated actin polymerization shapes how B lymphocytes probe the surface of antigen-presenting cells, promotes coalescence of B cell receptor (BCR) microclusters, amplifies BCR signaling, and enhances B cell activation.
The colonization of corals and their relatives by intracellular microalgae is facilitated by immunity proteins in the animal that contain thrombospondin-type-1 repeats, elucidating the inter-partner recognition processes required for the establishment of this ecologically important symbiosis.
Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.
