Questions & Step-by-Step Solutions
A 30-year-old woman is diagnosed with systemic lupus erythematosus (SLE). What type of immune response is primarily involved in this autoimmune disease?
Correct Answer: Humoral immune response
Step 1: Understand that systemic lupus erythematosus (SLE) is an autoimmune disease.
Step 2: Know that autoimmune diseases occur when the immune system mistakenly attacks the body's own cells.
Step 3: Identify that there are two main types of immune responses: humoral and cell-mediated.
Step 4: Recognize that a humoral immune response involves the production of antibodies by B cells.
Step 5: Learn that in SLE, the immune system produces autoantibodies, which are antibodies that target the body's own tissues.
Step 6: Conclude that the primary immune response involved in SLE is the humoral immune response due to the production of these autoantibodies.
Humoral Immune Response – The humoral immune response involves the production of antibodies by B cells, which is a key feature in autoimmune diseases like SLE.
Autoantibodies – In SLE, the immune system produces autoantibodies that target the body's own tissues, leading to inflammation and damage.
