  1. Immune System Κουσιάτζας Δημήτριος ΑΕΜ:27066 Καπέλλος Γεράσιμος ΑΕΜ:27249

  2. Immune System Innative Adaptive A) Skin and Mucosal membranes A) Cells • B lymphocytes • T lymphocytes B) Secreted soluble proteins • - Lysozyme • C-creative protein • Interferons • Complement system B) Antigen presenting cells C) Secrated chemicals • - Antibodies • Complement • Cytokines C) Cells • Macrophages • Mast cells • Natural Killer • Granulocytes

  3. Components of the immune system A) Cells 1) T-cells • Helper T-cells • Cytotoxic T-cells • Supressor T-cells 2) B-cells 3) Natural killer cells 4) Polymorphonuclear Leukocytes • Basophil • Neutrophil • Eosinophil 5) Macrophages 6) Dendritic cells

  4. B) Organs 1) Bone marrow 2) Thymus 3) Spleen 4) Lymph nodes

  5. C) Antibodies • IgM • IgA • IgD • IgG D) Complement system E) Hormones

  6. Immune response 1) Macrophage encounters a virus and consumes it 2) Macrophage digests the virus and displays pieces of the virus called antigens on its surface

  7. 3) Helper T cell recognizes the antigen displayed and binds to the macrophage. 4) This union stimulates the production of chemical substances

  8. 5) Killer T-cells multiply. B-cells multiply and produce antibodies 6) The killer T cells shoot holes in host cells

  9. 7) Antibodies bind to antigens on the surfaces of free-floating viruses 8) Activated T and B cells are turned off by suppressor T cells

  10. Conditions associated with the immune system 1) AIDS Cause: • -The Human Immunodeficiency Virus (HIV) causes AIDS • The virus attacks the immune systemthe body vulnerable to a variety of life-threatening illnesses and cancers. Treatment: -No cure for AIDS at present -Treatments that delay the progression of the disease: a) Antiviral agents b) Medication

  11. 2) Immune hemolytic anemia: Cause: - Premature destruction of red blood cells by the immune system Treatment: - Treatment with prednisone - Splenectomy - Immunosuppressive therapy

  12. 3) Idiopathic thrombocytopenic purpura: Cause: - Platelets are being destroyed by the immune system Treatment: • -Oral danazol • -High-dose gamma globulin injections • -Drugs that suppress the immune system • -Passing the blood over a Protein A (Prosorba) column, which filters antibodies out of the blood stream • -Anti-RhD therapy can also be useful in people with specific blood types

  13. Maintain a Health Immune System Vitamins Minerals Fatty acids Antioxidants
