Revealing the secrets of WRN
...ainer. "There are some 30,000 human genes, but the connections
among them are not like a wiring diagram -- they're more like the way an airline connects its routes, with many pathways going through a few major hubs. WRN is one of those hubs." Priscilla Cooper says, "SBDR investigators and others have shown that...
Genetic finding suggests alternative treatment strategy for common, complex skin disorders
...lled connexin 26, which makes a protein that forms connections
between skin cells that create the normal barrier. When the skin is intact, the production of connexin 26 is turned off once there is enough to hook all the skin cells together. When skin is damaged by a cut or a scrape, connexin 26 is produced whil...
New findings help pinpoint autism's genetic roots
...than normal and had a higher-than-normal number of connections

in the cortex and tuning the strengths of messages relayed by synapses. In mice, this period begins shortly after they open their eyes and begin to see. Previous research had determined that visual activity changes the level of expression of, or regu...
Selectively blocking inflammatory signals may protect mice from MS

Research uncovers signaling pathways related to brain-immune system links
...ling pathways in immune cells bolsters evidence of connections
between the central nervous system and the immune system. The findings may also advance the scientific foundation for a potential HIV treatment that may block the virus that causes AIDS. The cell culture study by a research team from The Children's H...

Patient's generosity after death leads to possible clues for lung disease

that allow molecules and ions to flow between cells. Junctions are composed of two hemichannels that bridge the intercellular space. Until now, scientists believed the disruption to occur at the site of glutamate channels. Glutamate is one of the bra...
