AIDS is an immunodeficiency syndrome. In the flow chart you drew for Question 11, describe where AIDS sufferers are deficient. Why can’t our immune systems fight off this disease?

Summary Introduction

To identify: The step of antibody-mediated immune response pathway in which the AIDS patient are deficient.

Introduction: AIDS stands for acquired immunodeficiency syndrome. This is caused by the human immune deficiency virus (HIV). The patients infected with HIV suffer from a collection of disorders. Worldwide about 33 million people are infected with HIV.

Explanation of Solution

Pictorial representation: Fig 1 represents the flow chart of the antibody-mediated immune response in response to a virus. The pathway involves activation of T-cells to form T-helper cells, which in turn activate B-cells to form plasma cells and memory B-cells.

Summary Introduction

To determine: The reason why the human body cannot fight off HIV infection.

Introduction: The antibody-mediated immune response protects the body against viruses and bacteria. The antibody-mediated immune response uses antibodies produced by plasma cells to specifically attack and destroy antigens. T-helper cells play an important role in the activation of B-cells.
