Scratch no more: Gene for itch sensation discovered

...enes they identified, GRPR stood out because it is present in only a few nerve cells in the spinal cord known to relay pain and/or itch signals to the brain. So they began to study some mice that were missing the GRPR gene to find out how they were different from normal mice. "The research was a little disa...

Identified main genetic variants involved in response to HIV

During the present study, obtained genetic data was compared to blood virus load in patients during the first two years after the infection, and also to the rhythm of immune degradation as a result of the infection. This type of comparison, known as association study, ...

Research team identifies new Alzheimer's gene

...and that the GAB2 protein produced by this gene is present in those brain cells containing tangles. When the researchers silenced GAB2 in preliminary studies it increased a molecular process thought to play an important role in the development of tangles. Based on these findings, the researchers hypothesize ...

Newly found sensing system enables certain bacteria to resist human immune defenses

...dies show that all three components of aps must be present for the system to function and effectively protect bacteria from AMPs. “We are aware that for gram-negative bacteria, PhoP/PhoQ has been called a premier target for antimicrobial drug discovery, but little corresponding work has been done with gra...

Researchers shed light on mechanism of action used by anti-cancer drug

...d by sorafenib remained largely unknown. In the present work, Grant and his team found that in human leukemia cells, sorafenib induces a process known as endoplasmic reticulum (ER) stress, which results from accumulation of misfolded proteins in the ER. The ER is a subcellular structure which plays a key ...

Massive herds of animals found to still exist in Southern Sudan

...ugh we were telling people that wildlife was still present in Southern Sudan, nobody believed us,” said Maj. Gen. Alfred Akwoch, undersecretary of the Ministry of the Environment, Wildlife Conservation, and Tourism. “Thanks to the aerial surveys, we now know that wildlife resources, including elephants, are ...

...entromeric and telomeric regions, until later. The present work extends the sequence into those regions." Repeating sequences are the hallmark of heterochromatin, and there are several distinct kinds. Simple, short repeats are called satellite DNAs, which tend to become more abundant near the centromeres...

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 response. The researchers found ...
