A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
Functional recapitulation of a likely evolutionary gain in gene expression shows that two genes are sufficient to switch mesoderm cell internalization from stochastic cell ingression to coordinated epithelial invagination.
Genes associated with age-based division of labor in ants exist in distinct regulatory and evolutionary contexts; genes up-regulated in young nurses are loosely connected and rapidly evolving while genes up-regulated in old foragers are highly connected and conserved.
TCR and CD40L microclusters are linked in synaptic ectosomes (extracellular vesicles) and released in the immunological synapse by helper T cells and induce dendritic cell maturation and cytokine production.
A plant virus, Tomato yellow leaf curl virus, manipulates the host preference of the vector insect whitefly to promote its transmission by inducing caspase-dependent apoptotic neurodegeneration in vector's brain.
Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.
