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
