TL;DR: The structure of the RBD suggests ways to make truncated disulfide-stabilized RBD variants for use in the design of coronavirus vaccines.
Abstract: The spike protein (S) of SARS coronavirus (SARS-CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction. The crystal structure at 2.9 angstrom resolution of the RBD bound with the peptidase domain of human ACE2 shows that the RBD presents a gently concave surface, which cradles the N-terminal lobe of the peptidase. The atomic details at the interface between the two proteins clarify the importance of residue changes that facilitate efficient cross-species infection and human-to-human transmission. The structure of the RBD suggests ways to make truncated disulfide-stabilized RBD variants for use in the design of coronavirus vaccines.

TL;DR: A new member of the p16INK4 family is isolated, p15INK4B, which is induced ∼30-fold in human keratinocytes by treatment with TGF-β, suggesting that pi5 may act as an effector of T GF-β-mediated cell cycle arrest.
Abstract: TRANSFORMING growth factor-beta (TGF-β) inhibits cell proliferation by inducing a Gl-phase cell cycle arrest1. Normal progression through Gl is promoted by the activity of the cyclin-dependent protein kinases CDK4 and CDK6 (ref. 2), which are inhibited by the protein p16INK4. We have isolated a new member of the p16INK4 family, p15INK4B. p15 expression is induced ∼30-fold in human keratinocytes by treatment with TGF-β, suggesting that pi5 may act as an effector of TGF-β-mediated cell cycle arrest. The gene encoding p15 is located on chromosome 9 adjacent to the p16 gene at a frequent site of chromosomal abnormality in human tumours (9p21).

TL;DR: It is reported that cultured hippocampal astrocytes can respond to glutamate with a prompt and oscillatory elevation of cytoplasmic free calcium, visible through use of the fluorescent calcium indicator fluo-3.
Abstract: The finding that astrocytes possess glutamate-sensitive ion channels hinted at a previously unrecognized signaling role for these cells. Now it is reported that cultured hippocampal astrocytes can respond to glutamate with a prompt and oscillatory elevation of cytoplasmic free calcium, visible through use of the fluorescent calcium indicator fluo-3. Two types of glutamate receptor--one preferring quisqualate and releasing calcium from intracellular stores and the other preferring kainate and promoting surface-membrane calcium influx--appear to be involved. Moreover, glutamate-induced increases in cytoplasmic free calcium frequently propagate as waves within the cytoplasm of individual astrocytes and between adjacent astrocytes in confluent cultures. These propagating waves of calcium suggest that networks of astrocytes may constitute a long-range signaling system within the brain.

TL;DR: Evidence of genetic linkage between the angiotensinogen gene (AGT) and hypertension is obtained, association of AGT molecular variants with the disease is demonstrated, and significant differences in plasma concentrations of angiotENSinogen among hypertensive subjects with different AGT genotypes are found.

TL;DR: This review, which examines adult stem cell niches and their impact on stem cell biology, highlights the importance of understanding how stem cells interact with their microenvironment to establish and maintain their properties.
