Turning the immune system against cancer

Medicine can now prevent a host of diseases with a mere shot of vaccine. Polio and smallpox are almost non-existent, and mumps and chicken pox are rarely seen nowadays.

Regulatory T cells learn what to protect while in the thymus and that everything the cells learn may not be good

Regulatory T cells, which function like immune system police, learn early in life what to protect, and that may include viruses, bacteria and tumors, researchers have shown.

Protein CD86 raises antibody output

Cancer immunologists here have discovered how a protein on the surface of antibody-making immune cells boosts the amount of antibody the cells make.

New way to assess pandemic potential of influenza viruses

Study provides first assessment of the risk of an H5N1 pandemic strain emerging from the combining of avian and human influenza viruses.

Polio making a comeback

The World Health Organization (WHO) says increasing numbers of people around the world are vulnerable to polio because they have not been previously exposed to the disease.

Poor sense of smell among alcoholics associated with prefrontal cognitive dysfunction

Prior research has shown that chronic alcoholism is associated with numerous olfactory deficits in odor judgment, odor identification, odor sensitivity, and the ability to qualitatively discriminate between odors.

Research findings may speed the development of vaccines for Chlamydia and other STDs

Using a novel mouse model that allows scientists to study how the immune system’s fighter cells respond to invaders in the genital tract during the initial stage of infection, researchers have found a way to track immunity against Chlamydia trachomatis.

Vaccination with irradiated Listeria induced protective T cell immunity

Vaccines made with bacteria killed by gamma irradiation, rather than by standard methods of heat or chemical inactivation, may be more effective, say researchers.

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.

Irradiation preserves T-Cell responses in bacterial vaccine

Findings could result in more potent vaccines that are relatively inexpensive to produce, easy to store, and that can be transported without refrigeration.

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.

Research offers new hope in helping elderly fight infections

Thousands of infections could be prevented each year in older people and hospital stays reduced following findings from two studies which show that imbalances in the immune systems of people aged over 65 make them more prone to illnesses like flu or bacterial infections as a result of cuts and falls.
