abzyme

Researchers have discovered an abzyme that can destroy the protein gp120 CD4 binding site.

A single abzyme can destroy thousands of HIV viruses.

The abzyme is derived from lupus patients and people who naturally resist HIV infection.

The abzyme does more than bind to the site, it actually destroys the site, rendering HIV inert, and then can attach to other viruses.

A HIV vaccine may be close with an abzyme that can destroy protein gp120, which all HIV variants use to attach to host cells.

An abzyme (from antibody and enzyme), also called catmab (from catalytic monoclonal antibody), is a monoclonal antibody with catalytic activity.
