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.

Dog DNA provides clues to combating diseases such as diabetes and multiple sclerosis in humans

Melbourne researchers are examining the DNA of dogs in a research project aiming at determining the genetic causes of common pet diseases - and to provide a model for combating diseases such as diabetes and multiple sclerosis in humans.
