How Bacterial Enzymes Use Ratchet Mechanisms to Break Down Collagen

Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of three protein strands twisted tightly together like a rope. Because of this sturdy structure, ordinary protein-cutting enzymes usually cannot break it down.

Excessive RNA Editing May Explain Neurological Differences in Down Syndrome

A collaborative research study co-led by scientists at the Icahn School of Medicine at Mount Sinai and the Liber Institute for Brain Development has for the first time identified a biological process that may help explain how the brain develops differently in people with Down syndrome. The study was a collaboration among scientists from the Icahn School of Medicine at Mount Sinai, the Lieber Institute for Brain Development, the Medical University of Sofia in Bulgaria, and the University of Arizona.

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.

Implantable Cell Factory Device Delivers Sustained Biologic Drug Production

Implanting living cells as long-term drug producers could transform treatment for numerous diseases, but it is difficult to house the tiny workers in quantities high enough to ensure dosage needs are met while also keeping the cells alive and thriving.

New Mechanism Links Mitochondria Dysfunction to T Cell Exhaustion

The immune system's killer T cells do a commendable job of detecting and destroying cancer cells. But the harsh environment at the heart of tumors often saps them of their vitality, pushing them into a state of permanent lassitude called "terminal exhaustion."
