Using gamma radiation preserves T-cell responses in bacterial vaccine

Using gamma radiation to inactivate bacteria for the preparation of vaccines, instead of traditional heat or chemical methods of inactivation, appears to create a vaccine that is more effective than so-called "killed" vaccines against disease, and has the added advantage of a longer storage life than "live" vaccines.

HIV mutation clue to why only some people develop AIDS dementia

The study of 18 HIV-positive subjects shows that HIV in the brain and central nervous system is genetically different from HIV that lives in the blood and peripheral tissues.

Heat sensitivity may make testicular cancer cells more susceptible to standard treatments and die off more readily

Experts at Johns Hopkins have linked scientific evidence spanning more than 30 years to suggest an explanation for why testicular cancer patients like seven-time Tour de France winner Lance Armstrong survive far better than patients with other advanced cancers.

How does the immune system isolate and destroy intruders?

Dendritic cells are the body's "watchdogs". They recognize and then degrade pathogens, isolating characteristic fragments that are recognized by the immune system thus triggering targeted responses.

Birch bark compound may be potent prostate cancer fighter

A compound found in the bark of the white birch tree - betulonic acid, a derivative of betulinol - may finally have been rendered a water-soluble, bio-available drug, and is already showing the potential to be a possible agent against prostate cancer - in cell culture and in an animal model.
