Missed signals? A new way we vary from each other biologically

Genetics has made huge strides over the past 20 years, from the sequencing of the human genome to a growing understanding of factors that turn genes on and off, namely transcription factors and the DNA "enhancer" sequences ...

Scientists map genes controlling immune system 'brakes'

Unlike most T cells, which launch immune responses against foreign molecules, regulatory T cells are the peacekeepers of the human immune system, damping down inflammatory reactions when they're not needed. Now, researchers ...

Discovery enables adult skin to regenerate like a newborn's

A newly identified genetic factor allows adult skin to repair itself like the skin of a newborn babe. The discovery by Washington State University researchers has implications for better skin wound treatment as well as preventing ...

Memory training for the immune system

After an infection of the human body with a pathogen, a cascade of reactions will usually be set into motion. Amongst others, specific cells of the immune system known as T cells get activated in the lymph node and will subsequently ...

A master regulator of kidney health?

End-stage kidney disease often begins with injury to podocytes. These highly specialized cells are a critical part of the glomeruli, clusters of capillaries that serve as the filtration units in our kidneys' tightly-packed ...

'Jumping' DNA regulates human neurons

The human genome contains over 4.5 million sequences of DNA called "transposable elements," virus-like entities that "jump" around and help regulate gene expression. They do this by binding transcription factors, which are ...

Scientists find a simpler way to make sensory hearing cells

Scientists from the USC Stem Cell laboratories of Neil Segil and Justin Ichida are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce ...
