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.
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.
To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.
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.
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.
