Antibody production

Definition

Antibody production is the process by which B cells, a type of white blood cell, produce antibodies in response to antigens. Antibodies are proteins that specifically recognize and neutralize pathogens such as bacteria and viruses.

5 Must Know Facts For Your Next Test

1. B cells are activated by helper T cells to start antibody production.
2. Each antibody is specific to a particular antigen due to its unique variable region.
3. The process of class switching allows a single B cell to produce different classes of antibodies (IgG, IgA, IgM, etc.).
4. Memory B cells are formed during an immune response and provide long-term immunity.
5. Antibodies can neutralize pathogens directly or mark them for destruction by other immune cells.
