Cellular communication relies on receptor molecules on the cell surface. The periodic uptake and sorting of these receptors, critical for their degradation or recycling, are governed by an elaborate ...

Scientists have identified a critical breakdown in the cellular machinery that produces proteins in aging brains.

tRNA is an important component of the biological synthesis of new proteins, as it carries a specific amino acid that will be incorporated to the protein through the ribosome machinery, as directed by ...

Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists at Weill Cornell Medicine have discovered that the nucleolus, long known ...

Findings reveal coronaviruses exploit stress-linked tRNA modifications, enhancing translation efficiency and offering insights for antiviral drug development.

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...
