Understanding Autoimmunity and the Immune System

What is the fundamental issue in autoimmune diseases?

• The immune system becomes too weak to function.

• The immune system attacks healthy body tissues.

• The immune system only attacks external pathogens.

• The immune system fails to recognize any threats.

How does the immune system identify threats?

• By recognizing specific shapes of proteins.

• By detecting the color of cells.

• By measuring the temperature of tissues.

• By counting the number of cells in an area.

What can trigger an autoimmune response?

• A common cold or flu.

• Adequate sleep.

• A balanced diet.

• Regular exercise.

How does the immune system react to a trigger event?

• It only targets external pathogens.

• It activates and gathers proteins from the battlefield.

• It ignores the event completely.

• It shuts down all immune responses.

What is the role of T cells in the immune response?

• They store genetic information.

• They attack and destroy pathogens.

• They transport oxygen in the blood.

• They produce insulin.

Which autoimmune disease affects the insulation of nerve cells?

• Lupus

• Type 1 Diabetes

• Rheumatoid Arthritis

• Multiple Sclerosis

What is a common symptom of most autoimmune diseases?

• Rapid weight gain

• Crushing fatigue and exhaustion

• Improved vision

• Increased energy levels

What is the main reason for the continuous nature of autoimmune attacks?

• The immune system is too weak to stop.

• The immune system lacks memory cells.

• The immune system is a self-reinforcing machine of destruction.

• The immune system is constantly regenerating.

Why do some harmful gene variants persist in the population?

• They are completely neutral in all contexts.

• They have no effect on survival.

• They were beneficial against past infectious diseases.

• They are always beneficial in modern environments.

What historical factor contributed to the prevalence of autoimmune diseases today?

• Increased physical activity

• Excessive hygiene practices

• Frequent pandemics in the past

• Lack of modern medicine
