Progress toward an antitumor vaccine

...containing compounds are completely ineffective at stimulating the immune system to form antibodies. “Immunization is only successful if the vaccine is anchored to an immunizing carrier protein by means of a spacer,” explains Kunz. This would be very easy to accomplish with polysaccharides, but turns out to be v...

Runners -- Let thirst be your guide

...e known as interleukin-6 (Il-6) is also capable of stimulating AVP secretion. Verbalis noted in his Sports Medicine paper that since 1985, “well over 100 individual cases” of EAH have been reported from physical exercise activities as diverse as forced military marches, prolonged hiking and marathon, ultra...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...s national studye to start protecting Americans by stimulating an immune response? A new national study led by Saint Louis University School of Medicine will attempt to answer this question. General routine vaccinations for smallpox were stopped in the United States in 1971, and the world was declared free ...

New Brandeis research sheds light on memory by erasing it

...y molecule." The research involved electrically stimulating neuronal synapses to strengthen them, a process known as long-term potentiation (LTP). This process has served as a model system for studying memory. CaMKII has been a leading candidate as a memory molecule because it is persistently activated after ...

How appetite-stimulating brain cells work overtime during fasting

...ng periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry. Now, a new study of mice reported in the January issue of the journal Cell Metabolism, published by Cell Press, reveals the complex series of molecular events that keep those neurons active. The research...

3 proteins may play important role in nerve-cell repair

...he nerve cells, while GPR12 was the most potent at stimulating growth of the nerve extensions. The study showed that blocking GPR3 greatly slows the growth of the nerve extensions. The researchers reversed this effect by restoring either GPR3 or GPR12 in the cells. High levels of the three proteins were also...

Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine

... scientists to design vaccines capable of directly stimulating helper T cells, aiding the development of vaccines not only for cancer but also for infectious diseases, says Dorothee Herlyn, D.V.M., senior author on the study and a professor in the Molecular and Cellular Oncogenesis and Immunology programs at Wis...

UW launches study testing adult stem cells for heart damage repair

... commercially produced protein (granulocyte colony stimulating factor). The protein helps to release blood-forming CD34+ cells from a subject's bone marrow into the bloodstream. Then, investigators use a cell separation system to remove from the subject's bloodstream a mix of cells containing the stem cells....

UCSF brain tumor vaccine trial shows promising results

...ation (trademarked as Oncophage) was effective in stimulating the patient’s immune system to attack the tumor cells, a function that is known medically as tumor-specific immune response. All the patients had recurrent, high-grade glioma, and all showed the immune response. The vaccine is made from the patient...

Antibody signal may redirect inflammation to fuel cancer

...tes apparently receive signals to switch programs, stimulating cell growth and increasing blood supply -- processes that would normally help healing from an infection, but can instead fuel cancer cell development." The researchers have not yet identified what specific signal or signals are involved, but preli...

"Zebrafish can survive pretty massive injury to the heart--the loss of about a quarter of their ventricle," said Kenneth Poss of Duke University Medical Center. The ventricle, which receives blood and then pumps it ...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

... longer). Existing vaccination methods depend on stimulating the body's immune system, so that white blood cells produce antibodies that attach to the surface of the virus and start the process of killing it. This works well for many diseases, such as smallpox, polio and measles, but is much less effective wi...

Cocaine high caused by interference in neuronal receiving stations

...n—the region known to be responsible for cocaine's stimulating effects. The researchers also analyzed whether this interaction between D2R and NR2B affected the rats' behavioral response to cocaine—specifically the hyperactivity and intensive sniffing and biting the drug elicits in the animals. They found that...
