Elderly mice yield clues to the process of growing old

... age related heart dysfunction, hair loss, loss of immune cells, anemia, and loss of male germ cells that lead to reduced sperm production and infertility. Intriguingly, the mice develop symptoms of old age, notably gray hair and hair loss, more commonly seen in humans than mice. Prolla suggests that new ...

Bacteria recognize antimicrobials, respond with counter-defenses

... sometimes deadly organism fights back against the immune system may lead to treatments that get around bacterial resistance. Work in this area may also suggest ways other disease-causing, Gram-negative bacteria maintain a stronghold in the midst of the body's attempts to get rid of them. Strangely enoug...

Discovery of T-cell 'traffic control' boosts new drug promise

... organs and tissues without compromising essential immune defenses. The emerging view brings together research findings on S1P's effect on both the immune system and the blood-circulating vascular system, showing how the two systems interact to regulate T...

These immunosuppressants can cause infection, hypertension, cancer, and other undesirable side effects. Therefore, specific suppression of the T cells that attack the transplanted organ is nee...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

... 18,000 deaths annually. Individuals with impaired immune systems are another highly susceptible group. Worldwide, the virus causes about one million deaths annually. Current methods of detecting the virus can take from two to six days, postponing effective treatment. The new, high-tech method uses multi-c...
