How T cells attack tumors

Our immune system struggles to eliminate tumors effectively. By unraveling its strategies, we can enhance its effects on tumor cells and so improve the clinical prospects of cancer immunotherapy.

More evidence that inflammation can fuel cancer

As evidence mounts that the body's normally protective inflammation response can drive some precancerous tissues to become fully malignant, UCSF scientists report discovering an apparent trigger to this potentially deadly process.

The present and future for influenza vaccines

The near inevitability that influenza will explode into a pandemic in the coming few years has kept researchers searching for a way to prevent the worst effects of infection. The ultimate prize is a highly effective vaccine that could be produced and deployed rapidly.

Primary targets of HIV-1 infection in human vagina identified

The primary targets of HIV-1 infection in the human vagina have been definitively identified in a new study published in the February 2007 issue of the journal Immunity. The findings are likely to guide development of new strategies that will prevent HIV-1 transmission.

Different treatments may be needed for chronic asthma, depending on whether it results from allergies or lung infections

Researchers have now identified a particular gene that influences how severe a M. pneumoniae infection may be, which in turn suggests that a different strategy might be needed for treating asthma resulting from this and similar lung infections rather than allergies.

Molecular change in 1918 pandemic influenza virus stops transmission

Experts at the Centers for Disease Control and Prevention have shown that a molecular change in the 1918 pandemic influenza virus stops its transmission in ferrets that were in close proximity, shedding light on the properties that allowed the 1918 pandemic virus to spread so quickly.

New smart anti-microbial approach to preventing tooth decay

Preventing cavities could one day involve the dental equivalent of a military surgical strike. A team of researchers supported by the National Institute of Dental and Craniofacial Research report they have created a new smart anti-microbial treatment that can be chemically programmed in the laboratory to seek out and kill a specific cavity-causing species of bacteria, leaving the good bacteria untouched.
