2 days ago · Antibodies, also known as immunoglobulins (Ig), are proteins produced by plasma cells (B lymphocytes) in response to the detection of a foreign substance called an antigen. The primary role …

Examples of antibody functions include neutralization of infectivity, phagocytosis, antibody-dependent cellular cytotoxicity (ADCC), and complement-mediated lysis of pathogens or of infected cells.

Antibodies are key to human health and modern medicine. They help your body fight infections and are used to detect, prevent and treat diseases. They identify and neutralize foreign substances such as …

Sep 25, 2025 · Antibodies are proteins that help your immune system respond to infections and illnesses by attaching to pathogens and neutralizing them.

Five isotypes of antibodies are found in different locations and perform different specific functions. The base of the Y plays a role in modulating immune cell activity. This region is called the Fc region, and …

Antibodies, or immunoglobulins, are the linchpins of the immune system's defense mechanisms. They perform some critical roles, primarily by recognizing and neutralizing pathogens that invade the body.

Antibodies circulate freely and act independently of plasma cells. Antibodies can be transferred from one individual to another to temporarily protect against infectious disease.
