Study Notes
White Blood Cells
- 5-9,000/ul in blood
- Granulocytes and Agranulocytes
Granulocytes
- Secretions include Interleukins, TNFα, prostaglandins, and bradykinin
Agranulocytes
- Lymphocytes including:
- NK cells: Immunological surveillance, cytotoxic cells, non-specific, for viruses, bacteria, parasites, tumour cells etc
- B cells: Produce Antibodies (plasma cells) which bind to antigens making the antigen recognizable by the immune system for destruction. This is called Opsonisation.
- T cells:
- TH: T helper cells
- TC: T cytotoxic cells /killer cells
- TS: T suppressor cells /regulatory cells
The Immune System
- A state of resistance against infection from a particular pathogen
- Recognizes “foreign” i.e.non-self from “self” antigens
- Detects antigens and initiates a complex series of steps designed to neutralise them
- Two basic types of immunity
- Non specific (Innate)
- Specific (Adaptive)
Non-specific/Innate Immunity
