eLife has published the following articles on SARS-CoV-2 and COVID-19.

Understanding how loss of CO₂/H⁺ vascular reactivity affects respiratory control may facilitate development of treatments for breathing problems in this population.

Balanced peptidoglycan synthesis requires regulators, including sigma-I and WalKR, that coordinate the diffusive action of class A PBPs and the directional motion of the MreB-directed elongasome.

Protein phosphatase 1 activity promotes cohesive collective cell migration by restricting actomyosin contractility to the periphery of the collective and maintaining proper cadherin–catenin complex protein levels at cell–cell junctions.

The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

Interbacterial interactions can promote mutagenesis, and possibly adaptation, when intoxicated cells survive exposure to type VI secretion-delivered DNA deaminase toxins.

Infection of human cells by influenza A virus induces changes in the alternative splicing of host genes that, in turn, promote viral replication.

Microbial-sensing TLRs drive responses to the microbiota, while nucleic-acid sensing TLRs control responses to endogenous ligands, revealing novel regulation of B-1a responses through integrated BCR/TLR mediated activation.

Tuning of BiP activity by Fic-mediated AMPylation is required for Drosophila photoreceptor plasticity and attenuation of the unfolded protein response.

Chemical modifications near the tRNA anticodon and specific mRNA–tRNA pairs combine to control the ribosomal three-nucleotide mRNA reading frame, essential for the sequential addition of amino acids into polypeptide chains.
