- Lymphocytes
- T helper cells
- Type of T lymphocyte
- Produce interleukin's (type of cytokine)
- Interleukin's produced then stimulate B cell activity
- This then increases antibody production
- stimulates production of other types of T cells
- and stimulates macrophages to ingest pathogens with an:
- Antigen-Antibody complex
- and stimulates macrophages to ingest pathogens with an:
- stimulates production of other types of T cells
- This then increases antibody production

- and stimulates macrophages to ingest pathogens with an:
- stimulates production of other types of T cells
- This then increases antibody production
- T Killer Cells
- Destroy the pathogen
- Produce a chemical called Perforin:
- This kills the pathogen by making holes in the cell membrane so its freely permeable
- T memory Cells
- Live for a long time
- Part of the immunological response
- If they meet an antigen for a second time, they divide rapidly to form T killer cell clones
- T regulator cells
- Surpress the immune system
- Stop immune response once a pathogen has been eliminated
- Checks the body recognises self antigens and doesn't set up autoimmune response
- Plasma Cells
- Produce antibodies to a particular antigen and release them into circulation
- Active ones only live for a few days
- Produce around 2000 antibodies per second when alive
- B effector cells
- divide to form plasma cell clones
- B memory cells
- Live for a very long time
- Provide immunological memory
- Programmed to remember a specific antigen
- Produce rapid response when a pathogen carrying the antigen is encountered again
- T Lymphocytes mature in Thymus gland
- B lymphocytes mature in the bone marrow
- T helper cells
