Scientists use gene transfer technology and common virus to block neuropathic pain

... nerve root makes the nerve degenerate and release substances that cause pain, according to Fink. A second group of eight rats received sham surgery, with no damage to their sciatic nerve. A third group served as normal controls. "When we study pain in people, we can ask them if it hurts," says Fink. "But you ...

'Underground' tunnels discovered as means for communication between immune system cells

...stem cells talk to one another solely by secreting substances such as cytokines, the authors say. It now seems clear that intercellular communication is much more complicated. While it would be fascinating to see this interplay inside living tissue, detecting the tiny tubules in such a complex environment may b...

Muscle repair: Making a good system better, faster; implications for aging, disease

...an exacerbate an injury, but they also can produce substances that may be required for repair. We would speculate that anti-inflammatory drugs may not be such a good idea if they're inhibiting repair-promoting macrophage functions; they may give some short-term relief following injury, but muscle repair may not...

U of MN researchers reverse memory loss in mice

...generally accepted that dementia was caused by two substances that accumulate in the brain: neurofibrillary tangles, which are tangled bundles of fibers in neurons, and amyloid deposits, a toxic build-up of plaque in the brain. The researchers found that even after the memory loss was regained in the mice, the ...

...iate than delayed rewards. A hallmark of addictive substances is that they provide an immediate reward in the intoxicating experience. When actively drinking, an individual's inhibition processes become impaired and can further contribute to poor decisions and excessive drinking. With prolonged bouts of drinkin...

Endocannabinoids ?the brain's cannabis ?demonstrate novel modes of action to stress

...vior. Cannabis works this way because it acts like substances that are produced inside our brains that are messengers between brain cells. Our work involves trying to understand what these substances, endocannabinoids, are for." She said they are particularly interested in how endocannabinoids influence oxytoc...

Climate model links higher temperatures to prehistoric extinction

...blood. When mast cells are activated, inflammatory substances such as histamine, heparin and a number of cytokines are rapidly released into the tissues and blood, promoting an allergic reaction. Mast cells are believed to be generated by different precursor cells in the bone marrow. In the in vitro portion ...

A protein in the eye may prevent immune response and protect eyes from disease

... the immune suppression did not occur when foreign substances were presented to the spleen by antigen presenting cells that did not have F4/80. "This led us to believe that the protein F4/80 had a direct role in stopping immune response," says Stein-Streilein. Although the mechanism by which F4/80 stimulates t...

Scientists discover the body's marijuana-like compounds are crucial for stress-induced pain relief

...emicals that tweak the levels of these transmitter substances in the brain," said Piomelli, "we might be able to boost their normal effects."
