Microneedle vaccine patches may effectively protect against flu

Recent research found that microneedle vaccine patches are more effective at delivering protection against influenza virus in mice than subcutaneous or intramuscular inoculation. A new, detailed analysis of the early immune responses by the Emory and Georgia Tech research team helps explain why the skin is such fertile ground for vaccination with these tiny, virtually painless microneedles.

High blood pressure due to stress maybe due to the immune system

If stress is giving you high blood pressure, blame the immune system. T cells, helpful for fighting infections, are also necessary for mice to show an increase in blood pressure after a period of psychological stress, scientists have found.

Combination of implanted DCs and EBRT effective in creating sarcoma tumor immune response

A team of 18 researchers at Moffitt Cancer Center in Tampa, Fla., have found that treating high-risk, soft tissue sarcoma patients with a combination of implanted dendritic cells (immune system cells) and fractionated external beam radiation (EBRT) provided more than 50 percent of their trial patients with tumor-specific immune responses lasting from 11 to 42 weeks.

Scientists determine chemical features of DHPS enzyme's active site

More than 70 years after the first sulfa drugs helped to revolutionize medical care and save millions of lives, St. Jude Children's Research Hospital scientists have determined at an atomic level the mechanism these medications use to kill bacteria. The discovery provides the basis for a new generation of antibiotics that would likely be harder for bacteria to resist and cause fewer side effects.

Europe conference to discuss on new HIV indicator diseases

Today, heterosexuals in Europe are at particular risk of carrying HIV for so long that they remain undiagnosed until their immune system starts to fail and they become ill. An international study under the leadership of the HIV in Europe initiative has now revealed that a number of diseases, including herpes zoster and certain forms of cancer, should be on the list of indicators for having HIV - and thus serve to prompt health care professionals to suggest an HIV-test to their patients.

New HS44 molecule inhibits lung metastasis

One type of white blood cell, the Natural Killer T Cells, fights against infections and tumours by freeing cytokine proteins which activate the body's immune response and destroy infected or malignant cells. To do so they must receive an activation signal. Specific receptors located on their surface act as switches: they activate the lymphocyte in presence of an antigen, a molecule which triggers alarm signals.
