B-Cells and Antigens

An infection is the invasion of a cell by pathogens including viruses and bacteria.

After invading the cell, the antigen multiplies and causes diseases that can invade entire tissues and organs, leading to death.

The human body produces B-cells that secrete Abs that attack these pathogens. The B-cells secrete Abs that bind to the pathogen.

Monoclonal Antibodies

MAb are produced by B-cells that can neutralize antigens, toxins, receptors, pathogens and helps natural killer cells recognize pathogens.

MAbs can also prevent infectious diseases by binding to the virus receptors thereby preventing the virus from entering the cell.

MAbs can be used to neutralize many different viruses including the following:


Dengue Fever

Yellow Fever



West Nile Virus
