Immunology Flashcards
Name and draw the 5 different antibodies
MADGE
Name the 2 different lymphoid organs
Primary and secondary
Give 2 examples of primary lymphoid organs
Bone marrow and thymus
What are the 2 functions of primary lymphoid organs
Produce lymphocytes and where they mature. Selection and deletion of auto-reactive cells to prevent autoimmunity
Give 2 examples of secondary lymphoid organs
lymph nodes and spleen
What i the function of secondary lymphoid organs
Maintain mature, naive lymphcytes and initiate the adaptive immune response
Where are B cells produced
bone marrow
What do b cells have on their surface
membrane bound immunoglobin
Where do T cells mature
in the thymus
What separates a helper t cell from a cytotoxic t cell
Helper = CD4 surface receptor Cytotoxic = CD8 surface receptor
Give some characteristic of an adaptive immune response
- Has memory
- Occurs in specialised places
- Has a unique antigen receptor on each lymphocyte
- Response is heightened second time
What cells are involved in an adaptive immune response
B and T cells
Describe some characteristics of an innate immune response
- Occurs locally
- There is no memory
- response is immediate and pathogen specific
What cells are involved in an innate immune response
Neutrophils and macrophages
What would the immune systems response be to a viral infection?
Recruitment of natural killer and cytotoxic T cells.
