Scientists directly view immune cells interacting to avert autoimmunity

...iating autoimmune attacks and the control of their actions by therapeutic regulatory T cells. The "nonobese diabetic" (nob) mouse model used in the research is considered the "prototypic" model for human type 1 diabetes, said Qizhi Tang, PhD, UCSF adjunct assistant professor in the UCSF Diabetes Center and ...

Pretreating rogue cancer cells with aspirin cripples their resistance to targeted therapy

...today are a site map and a report that details the actions required to save these sites and species. These items, along with a searchable database of sites, web links and media contacts for the Alliance's 52 member organizations, and photos of AZE sites and species for media use, can be found at: www.zeroex...

Synthetic Protein Eases Arthritis Symptoms in Mice

...nding to both TNFRs and thereby inhibit beneficial actions mediated by TNFR-2. The scientists next aim to develop a more stable form of P60 PLAD. Ultimately, they hope to test the protein in clinical trials. The research was also supported by the National Institute of General Medical Sciences, part of the ...

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

... term interests of fishing communities." Specific actions needed immediately include: Involve impacted communities in development of tsunami rehabilitation plans that consider the sustainable use of fishery resources and alternative employment opportunities, as required by capacity-control plans; Invest...

Pulp mill devastates swans' sanctuary in Chile

... in Chile. Although a series of lawsuits and other actions to force stronger action against the company have not so far succeeded, the case is now being heard by the Interamerican Court of Human Rights. "The sanctuary has suffered so much damage that we won't know, without more research, how long it may tak...

Chernobyl: The true scale of the accident

...ntamination and to analyse the impacts of remedial actions and radiation-reduction countermeasures. Better information needs to be provided to the public about the persistence of radioactive contamination in certain food products and about food preparation methods that reduce radionuclide intake. Restriction...

Dendritic cells offer new therapeutic target for drugs to treat MS and other autoimmune disease

...al compound called CEP-701, already known to block actions of the growth-promoting FLT3 gene, on human dendritic cells and in mice engineered to mimic multiple sclerosis, a disease that causes T-cells to destroy the myelin protein sheath around nerves in the central nervous system. The drug had a similar eff...

UQ scientists break new ground in fight against infection & chronic disease

...ies we were able to show, for the first time, both actions occur simultaneously and a common cellular pathway is used for releasing messengers and for eating microbes," she said. "This adaptation ensures the whole immune system responds to an infection in the most efficient and rapid way possible. "In so...

Emerald Spectre haunts Ontario's ash forests

...uncil of Canada (NSERC) reveals that unprecedented actions taken to stop the borer's spread have so far failed to halt its outward march. At risk are nine billion ash trees in the United States and Ontario, with an estimated value of more than $300 billion in the United States alone. "Its distribution conti...

Discovery that bacterium is phosphate gourmet key clue to what makes it most social of bacteria

... by the bacterium to process information to switch actions on or off. Myxococcus xanthus has an unprecedented number (around 150) of the signalling pathways known as "two component switches" which dramatically increases the level of complexity of information that can be processed by the bacterium. Dr Whitwor...

How fish hear and make sounds at same time

...al muscles to make sound, a number of synchronized actions take place. The ear and brain are cued to the exact timing of a self-generated sound, distinguishing it from outside sounds. Just prior to a voicing, the brain warns the ear it should become less sensitive. When analyzed closely, the vocalizations c...

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

...gs that block neural transmission by mimicking the actions of inhibitory agents like GABA, but it's difficult to give these drugs in adequate doses, because the same drug that blocks pain also interferes with brain activity, leaving people drowsy and unable to think clearly. "What we need is a way to releas...

Study: Plants use dual defense system to fight pathogens

... into a plant cell, the researchers focused on the actions of two of these molecules ?AvrRpt2 and AvrRpm1. Both target a protein key to Arabidopsis health­. The scientists found that both of these effector molecules effectively shut down the PAMP pathway. But the plant's R-proteins detect this, and come to ...

UCSD study clarifies insulin's role in blocking release of energy in patients with type II diabetes

...ed input of insulin and catecholamines. One of the actions of insulin --, the main energy storage hormone, is to block activation of the protein kinase A (PKA) enzyme. After a meal, insulin levels go up, and the body stores energy primarily as triglycerides, or fat, in adipose tissue to be used later. When e...
