Rethinking new therapies for Crohn's disease at U.Va.

...sponsible for Crohn's, while type 2 cytokines were linked to ulcerative colitis, another type of inflammatory bowel disease. Although the underlying cause of Crohn's remains unclear, Cominelli describes an intriguing hypothesis in which a defective innate immune system may be an important player. This...

Reduced fish stocks linked to increased bushmeat trade, wildlife declines in W. Africa

... availability of fish at local Ghanaian markets is linked to heavy overfishing in the Gulf of Guinea. UBC fisheries professor Daniel Pauly and others have identified the Gulf as one of the most overfished areas of the world, and now at risk of collapse. Declines in fish stocks in waters off West Africa hav...

...ties can cause SCID. The two most common forms are linked to the X chromosome. Patients with abnormalities on this chromosome either lack an enzyme called adenosine deaminase, or lack the ability to produce IL-2 receptor gamma chain, a molecule that T cells need to communicate with B cells. In some cases of...

Rare immunodeficiency provides new insight into immune system function

... T cell signaling molecules, such as Fyn, that are linked to reduced cytokine production in the SAP mutants. "Our data argue that a SAP/Fyn pathway may be required for the efficient recruitment of PKC-q and Bcl-10, as well as proper patterns of activation of NF-kB, and suggest a potentially novel pathway of...

Muscle loss from space travel, prolonged inactivity linked to two genes

After 10 days of reduced weight-bearing use, all groups of mice were assessed for changes in muscle fiber size, fiber phenotype, and activation of an inj...

A swathe of DNA containing multiple genes is missing in DiGeorge syndrome patients, and many are born with heart defects, immune deficiencies, and developmental and behavio...

Abundance of myostatin in infected swine may result in reduced muscle mass

...cle-bound, and a defective myostatin gene has been linked to double muscling in cattle and to abnormally large muscles in a German child. Johnson's team found a substantial increase in the amount of myostatin mRNA in the muscles of infected pigs. "We have shown, using an infectious disease model w...

How running made us human

Dr Glynne says: "The body's inability to regulate energy expenditure seems to play a key role in the development of sepsis-induce...

Study: Pigeons can sense the Earth's magnetic field; ability might allow them to return home

ICoMM joins a dozen other Census of Marine Life (CoML) research projects currently underway around the world. Unlike other CoML initiatives that focus on geograp...

Differences in gene usage dramatically change bacteria's 'lifestyles'

The distinction alters the bacteria's "lifestyles," or their ability to survive in different environments. Researchers say the finding shows that understanding such changes will likely help de...

Oral saline spray may slash spread of exhaled pathogens
