To enable tissue renewal, human tissues constantly eliminate millions of cells, without jeopardizing tissue integrity, form and connectivity. Scientists have revealed a new process which allows eliminated cells to temporarily protect their neighbors from cell death, thereby maintaining tissue integrity.

Mammals have a poor ability to recover after a spinal cord injury. A main reason for this is the formation of a scar that blocks tissue repair. Now, researchers have shown that the administration of drugs that target specific cellular components of this scar improve functional recovery after injury.

A research group has identified seven potential repurposed drugs for COVID-19 treatment through virtual screening and cell-based assays.

A team of biologists and chemists has discovered unlikely drug candidates, for treating liver fibrosis and other pathologies, among pest control chemicals.

Proteins such as beta-actin and gamma-nonmuscle-actin are almost identical however have distinct roles in the cell. Research has shown that protein function is determined by the nucleotide sequences rather than any differences in amino acid sequence.

Immunologists have identified a biological pathway that selectively controls how T follicular helper cells mature into functional components of the immune system.

MIT synthetic biologists have now developed an alternative approach to designing synthetic circuits, which relies exclusively on fast, reversible protein-protein interactions. This means that there's no waiting for genes to be transcribed or translated into proteins, so circuits can be turned on much faster, within seconds.

Researchers have uncovered the complex cellular mechanisms of Ebola virus, which could help explain its severe toll on humans and identify potential pathways to treatment and prevention.

Scientists have shown that the shape of extracellular vesicles in body fluids could be a biomarker for identifying types of cancer.

The quick expression of genes needed for learning and memory causes neurons to snap both strands of DNA in many more places and cell types than previously realized.
