Study Reveals T Cell Plasticity as a Key Driver of Systemic Autoimmunity

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of "good" microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.

New Neural Circuit Discovery Explains Precision Steering in Fruit Flies

When a fruit fly is navigating straight forward at high speed, why does it know that it's not straying off course? Because as long as the fly moves directly forward, the visual scene shifts from front to back in a near-perfect mirror image across both retinas – generating, in other words, a symmetrical visual motion pattern.

Johns Hopkins Team Identifies Distinct Subtypes of Senescent Skin Cells

Senescent skin cells, often referred to as zombie cells because they have outlived their usefulness without ever quite dying, have existed in the human body as a seeming paradox, causing inflammation and promoting diseases while also helping the immune system to heal wounds.
