Natural Tr1-like cells do not form a functionally stable memory response to allergens, and this instability may limit efforts to re-establish tolerance by expanding Tr1.
A previously undetected dynamic cell structure orients the mitotic spindle of germ stem cells and grows over one daughter cell, thus helping to balance niche retention with niche exit.
Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
At gastrulation, mesoderm arises as a migratory germ layer that will participate to both foetal and placental development through region-dependant adaptation of cytoskeleton composition, cell shape and migration mode.
The Atlantic herring has the lowest mutation rate yet estimated in a vertebrate species and this partially explains its moderate nucleotide diversity given the large population size.
The B-1a cell heavy chain antibody repertoire differs dramatically from the follicular and marginal zone B cell repertoire and is defined by distinct mechanisms driven by self antigens rather than antigens derived from the microbiota.
The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
