Definition
Meaning and Definition
The form of acquired immunity where B cells produce antibodies that neutralize pathogens or mark them for destruction.
A major arm of the adaptive immune system, also called humoral immunity, characterized by the production of specific antibodies by plasma cells in response to antigens. These antibodies circulate in bodily fluids and provide defense primarily against extracellular pathogens like bacteria, bacterial toxins, and viruses before they enter host cells.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or conceptual differences. Spelling of related terms (e.g., defence/defense, immunisation/immunization) follows regional conventions, but the term itself is invariant.
Connotations
Purely technical and neutral in both varieties.
Frequency
Exclusively used in medical, biological, and immunological contexts in both regions. Extremely rare outside these fields.

FAQ
Frequently Asked Questions
Antibody-mediated (humoral) immunity involves B cells producing antibodies that target pathogens in bodily fluids. Cell-mediated immunity involves T cells directly destroying infected host cells or activating other immune cells.
It is a key component of the adaptive (acquired) immune system, as it is highly specific to particular antigens and demonstrates memory.
Yes. Vaccination is a prime example where antibody-mediated immunity is developed without causing the full-blown disease, through exposure to a weakened or inactivated pathogen or its components.
In this context, 'mediated' means 'carried out by' or 'accomplished through the action of'. So, immunity that is carried out by or accomplished through the action of antibodies.
The form of acquired immunity where B cells produce antibodies that neutralize pathogens or mark them for destruction.
Antibody-mediated immunity is usually academic, medical, technical in register.
