Murine periosteum is highly enriched for osteoprogenitors, many of which express αSMA, but fracture callus chondrocytes are partially derived from other sources.

The distinct protein-RNA interactomes of HIV-1 RNA splice forms are revealed using a powerful multiplex strategy for RNA capture and mass spectrometric analysis.

The closest living relatives of animals, the choanoflagellates, switch from a flagellate to an amoeboid phenotype under confinement.

The mechanism that couples two rhythmic circuits is maintained over a large temperature range although both circuits are temperature-sensitive.

Single-cell dissection of recent neural crest derivatives in the vertebrate zebrafish reveals diverse transcriptomic signatures among differentiating posterior cell types during the embryonic to larval stage transition.

Patients with paucigranulocytic asthma may be more susceptible to severe influenza and could potentially be source of new, more virulent, influenza virus variants.

HIV-specific antibodies that mediate antibody-dependent cellular cytotoxicity vary in their paths to achieve function but commonly rely on mutations in multiple regions, including framework regions, to reach full potency.

Synchronized feeding and metabolic patterns with environmental light–dark cycles is critical to maintain energy homeostasis and requires the activity of leptin-receptor neurons in the dorsomedial hypothalamus.

The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.

During organismal development, CDK activity at mitotic exit is predictive of future cell behavior, indicating whether a cell will divide again or enter a quiescent state.
