What is Antibody Mediated Immunity or Humoral Immunity?
What are the 7 Steps of Antigen-Antibody Interactions?
It involves the antigen-antibody interactions to neutralize, eliminate or destroy foreign proteins.
The body learns to make enough of any specific antibody to provide long-lasting immunity and protection against specific organisms or toxins.
- The Seven Steps are:
- Antigen Recognition
- Lymphocyte Sensitization
- Antibody Production and Release
- Antigen-antibody binding
- Antibody-Binding reactions
- Sustained immunity or memory
Where are antibodies produced? What does it do?
- Antibodies are produced by B-Lymphocytes (B-Cells).
- Antibodies causes one of several actions to neutralize, eliminate or destroy that antigen.
What is the Function of a B-Cell?
The main purpose of the B-cells are to become sensitized to a specific foreign protein (antigen) and to produce antibodies directed specifically against that protein.
What is the B-Cells lymphocyte pathway?
- Starts out in the bone marrow as stem cells.
- Released into the blood and travel to secondary lymphoid tissues such as spleen, parts of lymph nodes, tonsils and mucosa of the intestinal tract.
Describe the Antigen Recognition stage of the Antibody Mediated Immunity:
- Macrophage recognizes the invader and attaches itself to the antigen.
- Macrophage does not attack but presents the antigen to the helper T-Cell.
- Both will process the antigen to expose the antigen's recognition sites.
