by Sarah C.p. Williams, Gladstone Institutes 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 at Gladstone Institutes, in collaboration with scientists at UC San Francisco (UCSF) and the Technical University of Munich...
UNIVERSITY OF WÜRZBURG IMAGE: SCHEMATIC REPRESENTATION OF THE FUNCTION OF BATF3. IN THE UPPER HALF YOU CAN SEE THE PHYSIOLOGICAL FUNCTION AND THE CONSEQUENCES IF THIS FACTOR IS MISSING (KNOCKOUT). THE LOWER HALF SHOWS. After an infection of the human body with a pathogen, a cascade of reactions will usually be set into motion. Amongst...
By Ecole Polytechnique Federale de Lausanne Scientists at EPFL, ETHZ and Harvard Medical School/Boston Children’s Hospital have developed an implantable technology that enabled the discovery of an interaction between sensory neurons and immune cells. Pain is a protective mechanism, alerting us to danger by generating an unpleasant sensation. The warning message is carried to the spinal...
A new study in mice adds to the evidence suggesting that the immune system not only attacks invading pathogens but can also influence mood. A new study finds further evidence of the link between the immune system and behavior. Over the past few years, scientists have discovered some intriguing links between immunity and the mind....
Durham, NC – Human pluripotent stem cells (hPSCs) hold promise in the field of regenerative medicine for how they give rise to every other cell type in the body and for their ability to propagate indefinitely. Their potential, however, is hampered by the body’s tendency to reject any “allogeneic” cells or tissue, which means that...

The red inside some cells indicates which neurons were recently active (cFos). Credit: Jeremy Boringer Scientists at Cold Spring Harbor Laboratory (CSHL) and Stanford University have pinpointed the circuit in the brain that is responsible for sleepless...
By Rich Haridy September 09, 2020 An animal study has revealed a part of the brain activated by stress can suppress immune system activity and heighten insomnia A new study, led by neuroscientists from Stanford University, has homed in on the specific brain circuit responsible for stress-induced insomnia. The research suggests this same circuit is...
by University of Rochester Medical Center New research details how the complex set of molecular and fluid dynamics that comprise the glymphatic system—the brain’s unique process of waste removal—are synchronized with the master internal clock that regulates the sleep-wake cycle. These findings suggest that people who rely on sleeping during daytime hours are at greater...
