Research Shows How HIV Protein Gets Into Cells

A team of researchers from University of Illinois has solved the mystery of how a protein associated with the HIV virus can cross cell membranes. Their findings could improve the design of therapeutic agents that cross a variety of such membranes.The TAT protein transduction domain of the HIV virus is a tiny part of the overall TAT protein (containing only 11 amino acids), but it can slip across lipid-rich membranes that are designed to keep things out. Although it is not involved in transmittin…
