title: NCI investigators find CD4 t-cell protectors.
abstract: A senior investigator with the National Cancer Institute discusses in this question-and-answer interview some recent findings that a novel human antibody is effective in preventing some strains of HIV from entering CD4 t-cells. The researchers named the newly identified antibody X5 and found that it reacts strongly against a highly conserved region of the glycoprotein gp120.
