The structure of gp41with its membrane anchors highlights the flexible linkage of the transmembrane regions and the fuson peptides, which generates an asymmetric conformation, a potential target of MPER bNAbs.
The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.
The general transcription elongation factor NusG functions as an intrinsic termination factor in Bacillus subtilis and together with NusA coordinates global gene expression including the motility regulon.
Transcription changes in cells taken from bronchoalveolar fluid of COVID-19 patients indicate severe disruption of coagulation and fibrinolytic pathways in the lung and suggest similar processes in other organs.
Experiments in a mouse model for Alzheimer’s disease using germ-free and conventionally housed animals reveal that microbiota-derived short-chain fatty acids promote the deposition of cerebral Aβ plaques.
