Summary Introduction

To determine: Whether the given results support the hypothesis that the virus is adapting to host defenses.

Introduction: Human Immunodeficiency Virus (HIV) is a group of retroviruses that are sexually transmitted from one to another. It causes a disease that lead to life-threatening infections called AIDS. Here, the immune system fails or weakens due to viral infection and is accompanied with the development of many infections. Certain proteins called Human Leukocyte Antigens (HLA) are produced and displayed by our cells that act as a marker for the identification of unusual invaders in the body. Each unique marker is produced for the determination of self-cells versus the invaders by the immune system.
