Once inside the compartment that houses and protects the brain, a second set of liposome-embedded antibodies seeks out the human insulin receptor found in the membranes of brain cancer cells. The insulin receptor antibody latches on to the tumor's insulin receptors. The liposome, and its contents, uses...

The search for a safer smallpox vaccine: New data released on promising candidate

... has demonstrated that the vaccine, given to mice, protects against a virus related to smallpox that has been aerosolized. According to Buller, this closely models how smallpox could be delivered during a bioterrorist attack. Buller and his colleagues, working in accordance with VaxGen and the National Insti...

Study may improve survival of transplanted livers

...the transplant, the study indicated. "Nitric oxide protects the liver during the reperfusion phase, after ischemia has occurred, and this means we can intervene in a meaningful way," said Lemasters. "We can treat after disease onset." Because it reacts rapidly with oxygen, nitric oxide can cause damage to the...

Cancer drug resistance research leads to possible therapeutic target for Alzheimer's disease

...cells, they are more vulnerable to damage. Myelin protects them by sheathing their axons--threadlike extensions of the nerve cells--in alternating layers of protein and fat. A new model of human brain aging (Neurobiology of Aging, January 2003) postulates that mid-life breakdown of myelin could be a possibl...

Stem cells more vulnerable to toxic chemotherapy when protective molecule is disabled

But the cells must also protect themselves from excess heme by making BCRP, which is capable of binding to these oxygen-carrying...

Experimental smallpox DNA vaccine protects primates from lethal monkeypox

...er, epidemiological studies have shown that Dryvax protects humans against both smallpox and monkeypox. All the orthopoxviruses--vaccinia, monkeypox, and variola--are highly similar in the majority of their nearly 200 proteins, which partially accounts for the cross-protection among these viruses. However,...
