Which of the following is/are examples of autoimmune disease?
a. Type 1 diabetes
b. Multiple sclerosis
c. Graves’ disease
d. Rheumatoid arthritis

Verified step by step guidance

Understand the concept of autoimmune diseases: Autoimmune diseases occur when the immune system mistakenly attacks the body's own tissues, perceiving them as foreign invaders. This leads to inflammation and damage to various organs or systems.
Review the examples provided in the question: Type 1 diabetes, multiple sclerosis, Graves’ disease, and rheumatoid arthritis. Each of these conditions is associated with immune system dysfunction.
Analyze Type 1 diabetes: In this condition, the immune system attacks the insulin-producing beta cells in the pancreas, leading to insufficient insulin production. This is a classic example of an autoimmune disease.
Analyze multiple sclerosis: This disease involves the immune system attacking the protective myelin sheath surrounding nerve fibers in the central nervous system, disrupting communication between the brain and the rest of the body. It is an autoimmune disease.
Analyze Graves’ disease and rheumatoid arthritis: Graves’ disease is an autoimmune disorder where the immune system stimulates the thyroid gland to produce excessive hormones. Rheumatoid arthritis involves the immune system attacking the synovial lining of joints, causing inflammation and pain. Both are examples of autoimmune diseases.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Autoimmune Disease

Autoimmune diseases occur when the immune system mistakenly attacks the body's own cells, tissues, or organs. This can lead to inflammation and damage, resulting in various health issues. Common examples include Type 1 diabetes, where the immune system attacks insulin-producing cells in the pancreas, and rheumatoid arthritis, which affects the joints.

Immune Tolerance

Type 1 Diabetes

Type 1 diabetes is an autoimmune condition where the immune system destroys insulin-producing beta cells in the pancreas. This leads to high blood sugar levels and requires lifelong management through insulin therapy. It typically manifests in childhood or adolescence but can occur at any age.

Multiple Sclerosis

Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system, where the immune system attacks the protective myelin sheath covering nerve fibers. This can result in communication problems between the brain and the rest of the body, leading to symptoms such as fatigue, difficulty walking, and vision problems.
