Pathogen (antibody-mediated neutralization)

The phrase "Pathogens via antibody-mediated neutralization" does not refer to a specific molecular target such as a receptor, enzyme, or protein. Instead, it describes the general process by which **neutralizing antibodies** bind to pathogens—such as viruses or bacterial toxins—and block their ability to infect host cells. This is achieved by preventing the pathogen from interacting with its cellular receptor or undergoing necessary structural changes for cell entry. While this mechanism is central to many vaccines and immunotherapies, "pathogen" itself is not a molecular target; rather, it is the object being targeted by immune molecules like antibodies. Therefore, this entry does not correspond to a canonical therapeutic target but instead refers broadly to an immune defense mechanism[1][2].
