New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

.... "A light went on when I saw that the rare human monoclonal antibodies had physical characteristics very similar to autoantibodies found in autoimmune disease ?in other words, to the antibodies the normal immune system does not allow to be made," Haynes said. The results provide a new goal for future HIV res...

Secrets to antibody's success against West Nile Virus surprise scientists

...ines for related viruses including dengue fever. A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. Instead, the antibody somehow stops the infectious p...

New Lab Research May Help Those Deafened By Immune System Attack

... or destroy hearing. The U-M team has developed a monoclonal antibody, called KHRI-3, that attaches to IESCA in the inner ear, and can be detected in living animal systems and cell cultures. It has allowed them to study IESCA's role in hearing loss in animal models, and show that damage to the inner ear caused...

Treatments have same target, different responses for lung cancer patients with genetic mutation

...ness of another type of drug that targets EGFR--a monoclonal antibody called cetuximab, which is approved for the treatment of metastatic colorectal cancers that overexpress EGFR. Cetuximab targets EGFR by preventing its activation by extracellular signals, or signals occurring outside of the cell, as opposed ...
