Study Notes
Function of Antibodies
- Primary function is to identify and neutralize foreign objects like bacteria and viruses.
- They tag pathogens for destruction by other immune cells, facilitating targeted immune response.
Composition of Antibodies
- Antibodies are composed of proteins, specifically made up of four polypeptide chains: two heavy chains and two light chains.
- Each antibody has a unique variable region that allows it to bind specifically to antigens.
Role of Antibodies in the Immune System
- Antibodies play a critical role in mediating immune responses by marking pathogens for destruction.
- They can neutralize toxins and block interactions between pathogens and host cells, preventing infection.
Production of Antibodies in the Body
- Antibodies are produced by B lymphocytes, a type of white blood cell.
- Upon activation by an antigen, B cells differentiate into plasma cells, which secrete antibodies into the bloodstream.
Triggers for Antibody Production
- Antibody production is triggered by exposure to antigens, which can be components of pathogens or foreign substances.
- Vaccination can also stimulate the immune system to produce antibodies against specific pathogens without causing disease.
