10 Questions
What is the concept that opposes hypersensitivities?
Immunotolerance
Which of the following is not directly related to hypersensitivities?
Sexually transmitted infections (STIs)
What is a result of a lack of immunotolerance?
Autoimmune diseases
Which of the following is a type of immune system dysfunction?
All of the above
What is the term for a state of impaired immune function?
Immunodeficiencies
What is the primary distinction between immunotolerance and autoimmune diseases?
Immunotolerance involves the suppression of immune responses to prevent harm to the body, whereas autoimmune diseases occur when the immune system mistakenly attacks healthy cells and tissues.
How do hypersensitivities relate to immunodeficiencies?
Hypersensitivities involve an overactive immune response, whereas immunodeficiencies involve a weakened or impaired immune response.
What is the common link between blood-borne infections and sexually transmitted infections (STIs)?
Both blood-borne infections and STIs are types of infectious diseases that can be transmitted through bodily fluids.
What is the primary consequence of a lack of immunotolerance in the context of autoimmune diseases?
The primary consequence is the immune system's attacks on healthy cells and tissues, leading to tissue damage and disease.
How do immunodeficiencies and autoimmune diseases both contribute to the development of diseases?
Immunodeficiencies increase the susceptibility to infections, while autoimmune diseases lead to tissue damage and disease through the immune system's attacks on healthy cells and tissues.
Study Notes
Hypersensitivities
- Hypersensitivities can be classified into different categories
Immunotolerance/Suppression
- Immunotolerance occurs when the immune system fails to respond to an antigen
- Immunological tolerance can be specific or non-specific
- Suppression occurs when the immune response is actively suppressed
Autoimmune Diseases
- Autoimmune diseases occur when the immune system attacks the body's own tissues
- Examples of autoimmune diseases include rheumatoid arthritis and lupus
- Autoimmune diseases can be classified into different types
Immunodeficiencies
- Immunodeficiencies occur when the immune system is weakened or absent
- Examples of immunodeficiencies include HIV and severe combined immunodeficiency (SCID)
- Immunodeficiencies can be classified into different types
Blood Borne Infections
- Blood-borne infections can be transmitted through blood products or infected needles
- Examples of blood-borne infections include HIV and hepatitis
- Blood-borne infections can be classified into different types
Sexually Transmitted Infections (STIs)
- Sexually transmitted infections (STIs) are caused by bacteria, viruses, or parasites
- Examples of STIs include chlamydia, gonorrhea, and syphilis
- STIs can be classified into different types
