Immunology Quiz: Types of Responses

Study Notes

Hypersensitivity Reaction: an exaggerated or inappropriate immune response to an antigen, resulting in tissue damage or disease.
- Classified into 4 types: Type I, II, III, and IV
Immune Response: a specific reaction to an antigen, involving activation of immune cells and production of antibodies.
- Involves both innate and adaptive immunity
Inflammatory Response: a nonspecific response to tissue damage or infection, characterized by increased blood flow, swelling, and pain.
- Involves activation of immune cells, release of chemical mediators, and increased blood vessel permeability

Acute Inflammatory Response:
- Immediate response to tissue damage or infection
- Characterized by increased blood flow, swelling, and pain
Chronic Inflammatory Response:
- Prolonged response to persistent tissue damage or infection
- Characterized by tissue repair and remodeling

Neutrophils: primarily involved in acute inflammatory response
Macrophages: involved in both acute and chronic inflammatory response
Lymphocytes: involved in adaptive immune response
Dendritic Cells: involved in antigen presentation and activation of immune cells

Histamine: released by mast cells, causes increased blood vessel permeability and smooth muscle contraction
Bradykinin: a vasodilator, increases blood flow to affected area
Prostaglandins: involved in pain and fever response
Cytokines: signaling molecules involved in activation and regulation of immune cells
