  • lymphocytes are a type of white blood cell that identifies non self cells
  • once lymphocytes detects non self cells they trigger a immune response
  • lymphocytes can detect pathogens toxins non self cells and abnormal cells
  • an antigen is a protein in the cell surface membrane that triggers an immune response
  • lymphocytes use antigens to detect non self cells
  • becauase of the range of shapes protein can be due to the tertiary structure proteins are good at distinguishing cells
  • lymphocytes detect non self cells based on their antigenes
  • all lymphocytes have antigen receptors on their surface and these receptors are complementary to a specific antigen
  • when the receptor and antigen bind together it activates lymphocytes to trigger immune response
  • lymphocytes trigger a specific immune response as a single lymphocytes has one type of antigen receptor complementary to a single antigen
  • phagocytes are a type of white blood cell that detects non self cells
  • phagocytes are non specific to antigens and pathogens
  • phagocytes have receptors complementary to molecular patterns found in all pathogens therefore it trigger a non specific immune response
  • phagocytes trigger non specific immune response as the recognise all pathogens
  • cytokines are produced by phagocytes that have engulfed a pathogen they then attract other phagocytes to site
  • opsonins bind to antigens preventing pathogen from repelling phagocytes
