Definition
| antigens, cell-mediated immune response and humoral immune response. |
|
|
Term
|
Definition
| antibody mediated; antibodies attack invaders to be destroyed by phagocytes or complement. |
|
|
Term
|
Definition
| deals with lymphocytes themselves defending the body and not antibodies. Lymphocytes attack directly by lysing foreign cells or indirectly by releasing chemicals that activate other systems. |

|
|
Term
|
Definition
| antigens are immunogenic (can activate lymphocytes) and react with them pollen, microorganisms. |

| 4 examples of alterations of immune responses |
|
Definition
| Allergic or hypersensitivity disorders, Autoimmune disorders,transplantation rejection, immunodeficiency states |
|
|
Term
| Hypersensitivity reactions: Type I |
|
Definition
| immediate hypersensitivity disorders. Ex. Dog allergy. Mast cells attach to IgE |
|
|
Term
| Hypersensitivity reactions: Type II |
|
Definition
| Cytotoxic hypersensitivity. Antibody mediated, the antibody produces the reaction. Food and drug allergy |
|
|
Term
| Hypersensitivity reactions: Type III |
|
Definition
| Immune complex mediated disorders. Antibody combines with the antigen, and produces the reaction. Viral pneumonia. |
|
|
Term
| Hypersensitivity reactions: Type IV |
|
Definition
| Delayed hypersensitivity. Poison Ivy. |
|
|
Term
|
Definition
| When an allergic hypersensitivity affecting parts of the body not in direct contact with the allergen |
|
|
Term
|
Definition
| A class of antigens which cause non-specific activation of T-cells, releasing cytokines |
|
|
Term
|
Definition
| When the body recognizes its own tissues as foreign and attacks them, the condition is called autoimmunity. |
|
|
Term
|
Definition
| Nerve cells, Central nervous systems. Removes the myelin sheaths. |
|
|
Term
|
Definition
| Central nervous systems, attacks the receptors either by being blocked or broken. |

Definition
| A hyper thyroid condition, increases metabolism, blood pressure, lose weight, heart rate, bulging eyes |
|
|
Term
| Type I (juvenile) diabetes mellitus |
|
Definition
| Pancreas is affected. Body is attacking the cells that cause insulin to decrease |
|
|
Term
| Systemic lupus erythematosus, (SLE) |
|
Definition
| Mostly the kidney. Purple rash, across the chest or face. Lupis, is caused by the immune response. |
|
|
Term
|
Definition
| Kidney is affected. Blood in the urine, since the strainer cannot strain, protein in the pee. |
|

Term
|
Definition
| Affects joints and cartilage around the joints. Could test blood, and the cartilage will be gone. |
|
|
Term
| Transplantation immunopathology |
|
Definition
| The cell surface antigens that determine whether transplanted tissue is recognized as foreign are the MHC or human leukocyte antigens (HLA). |
|
|
Term
|
Definition
| if the donor and recipient share similar HLA types |
|
|
Term
|
Definition
| if they are identical twins |
|
|
Term
|
Definition
| if they are the same person |
|
|
Term
| host versus graft disease results (HVGD) |
|
Definition
| If the recipient’s immune system tries to eliminate the cells bearing foreign MHC antigens |
|
|
Term
| graft versus host disease (GVHD) |
|
Definition
| If the cellular immune system of the transplanted tissue attacks recipient tissue |
|
|
Term
