In this video we see a killer T-cell of the immune system attacking a cancer cell.

(Medical Xpress) -- Cambridge scientists have, for the first time, created cerebral cortex cells – those that make up the brain’s grey matter – from a small sample of human skin.  The researchers’ findings, which were funded by Alzheimer’s Research UK and the Wellcome Trust, were published today in Nature ...

(PhysOrg.com) -- The molecular pathway that carries time-of-day signals from the body's internal clock to ultimately guide daily behavior is like a black box, says Amita Sehgal, PhD, the John Herr Musser Professor of Neuroscience and Co-Director, Comprehensive Neuroscience Center, at the Perelman School of Medicine, University of Pennsylvania.

University of British Columbia researchers have discovered the molecular pathway that enables receptors inside immune cells to find, and flag, fragments of pathogens trying to invade a host. The discovery of the role played by the molecule CD74 could help immunologists investigate treatments that offer better immune responses against cancers, ...

Immune cells capable of attacking healthy organs "see" their targets differently than do protective immune cells that attack viruses, according to work published online this week in the Journal of Experimental Medicine. During development, T lymphocytes are screened for their ability to recognize normal tissue. Such autoreactive cells are typically ...

A research team led by UC Davis Health System scientists has developed a novel technique to enhance bone growth by using a molecule which, when injected into the bloodstream, directs the body's stem cells to travel to the surface of bones. Once these cells are guided to the bone surface ...

Repeated, low-dose injections of mononuclear cells derived from human umbilical cord blood (MNC hUCB, tradename: U-CORD-CELL™) have been found effective in protecting motor neuron cells, delaying disease progression and increasing lifespan for mice modeling amyotrophic lateral sclerosis, or ALS, also referred to as Lou Gehrig's disease, report University of South ...

Taste receptors on the tongue help us distinguish between safe food and food that's spoiled or toxic. But taste receptors are now being found in other organs, too. In a study published online the week of February 6 by the Proceedings of the National Academy of Sciences of the USA, ...

(University of Pennsylvania School of Medicine) The molecular pathway that carries time-of-day signals from the body's internal clock to ultimately guide daily behavior is like a black box, says Amita Sehgal, Ph.D. Now, new research from the Sehgal lab is taking a peek inside, describing a molecular pathway and its ...

University of Illinois researchers determined that an adult stem cell present in muscle is responsive to exercise, a discovery that may provide a link between exercise and muscle health. The findings could lead to new therapeutic techniques using these cells to rehabilitate injured muscle and prevent or restore muscle loss ...
