...an help in the most difficult-to-detect cases. CAD prompts the radiologist to re-examine the films, and the radiologist decides whether "true areas of concern are present at the highlighted locations before making the final diagnosis," she said. The study also looked at the false-positive mark rate, i.e. the...NIAID begins enrolling volunteers for novel HIV vaccine study
...to stimulate HIV-specific cellular immunity, which prompts the body to produce T cells that kill HIV-infected cells. In previous smaller trials, this vaccine was found to be safe and to induce cellular immune responses against HIV in more than half of volunteers.

How do parents perceive physical and psychosocial aspects of emotional, social and school functioning by these children? Researchers used the Pediatric Quality of Life Inventory to study...Lab study defines and blocks mechanism that lets brain tumors sidetrack immune response
... of a protein called interleukin-12 (IL-12), which prompts the immune system's CD4+ T lymphocytes to launch a T helper type 1 (Th1) response attack mode. Lymphocytes would swarm to the source of the antigens and attack the tumor cells. Instead, the researchers found, COX-2 and a hormone-like substance it sy...Duke scientists overcome immune resistance in dendritic cell vaccines for cancer
...e of dendritic cells that recognizes the PAMPs and prompts them to silence regulatory T-cells. The sites are called Toll-like receptors, and activating them is critical to temporarily silencing regulatory T-cells.
