Question

In which of the following diseases the autoantigens are β-cells?

(a) Myasthenia gravis

(b) Insulin-dependent diabetes

(c) Multiple sclerosis

(d) Chronic anaemia

I had been asked this question in a national level competition.

My question is based upon Human Health and Disease topic in section Human Health and Disease of Biology – Class 12

Answer 1

The correct choice is (b) Insulin-dependent diabetes

For explanation I would say: In Insulin-dependent diabetes, the autoantigens are β-cells. Autoantigens are substances of the patient’s body that develop antigenic activity and hence destroy the patient’s body cells and tissues.
