The researchers from California Institute of Technology have discovered a new antibody that can make it easier to detect and neutralize HIV virus in an infected patient. Proteins called broadly neutralizing antibodies (bNAbs) are a promising key to prevent infection by HIV — the virus that causes AIDS. bNAbs have been found in blood samples from some HIV patients whose immune systems can naturally control the infection. The process of HIV infection begins when the virus comes into contact with human immune cells called T cells that carry a particular protein called CD4 on their surface
