Why Study immunology?
|
1.) Infectious Diseases
2.) Mechanisms of pathogenicity - Virulence factors 3.) Vaccine development |
|
What are the diseases that are caused by a disturbed immune system?
|
1.) Allergy
2.) Autoimmunity |
|
The immune response to innocuous materials (allergens).
ex.) Asthma |
Allergy
|
|
Immune responses to transplanted tissue.
|
Graft Junction
|
|
What is the definition of Immunodeficiency?
|
Defects in immune responses
Ex.) CMI, T-Cells, B-Cells, Complement, and phagocyte deficiencies. |
|
What are 2 manipulations of immunity to treat disease?
|
1.) Immunosuppression: Treatment of immune diseases
2.) Immunoregulation: Immunotherapeutic interventions |
|
1.) 1st line of Defense
2.) 2nd line of Defense 3.) 3rd line of Defense a.) Cellular and humoral defenses (innate) b.) Skin & Mucous membranes c.) Cellular and humoral defenses (acquired) |
1.) b
2.) a 3.) c *the cold virus can escalade to pneumonia because it inhibits the actions of the 1st line of Defense (rapidly regenerating surfaces, peristaltic movement, mucociliary escalator, etc.) |
|
Anatomical defenses, inflammation, fever, and phagocytic barriers are involved in what type of immunity?
|
Innate (natural) immunity: Inbuilt immunity to resist infection.
|
|
Specificty, Tolerance, and Memory are involved in what type of immunity?
|
Acquired (adaptive) immunity: Immunity established to adapt to infection.
|
|
Cells, proteins and supporting systems that kill or inactivate invaders (such as bacteria, viruses, fungi, and protozoa), reacts to chemicals and allergens, and monitor ever cell in the body for cancer.
|
The immune system
|
|
What are the advantages to the Immune system?
|
1.) Kills Bacteria
2.) Kills cells infected w/ bacteria or viruses 3.) Inactivates or destroys viruses 4.) Inactivates or destroys toxins, kills cancer cells |
|
What are the disadvantages to the Immune system?
|
1.) Contributes to allergies
2.) Rejects transplanted tissues 3.) Sometimes mistakenly attacks itself, Autoimmune diseases |
|
T or F. An antigen is a substance that illicits an immune response and can be of any size.
|
False. The substance has to be greater than 10,000 MW in order to be am antigen.
|
|
What is an important aspect to a vaccine?
|
The immune system detects antigens regardless of its source.
|
|
What are the components of a microbe that are antigen?
|
Proteins, cell membrane, cell wall, and envelope.
