Study Links ER Stress From Fat Buildup to Senescence

When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate.

Sweat Peptide Dermcidin Prevents Flu Virus Entry Into Cells

A research team led by the Fisabio Foundation has demonstrated that dermcidin, an antimicrobial peptide produced constitutively by the human body, also exhibits antiviral activity against the influenza virus. The study also shows that people who do not develop flu-like symptoms have higher baseline levels of this molecule, which could be associated with lower susceptibility to infection.
