Immune Responses and Cell Signaling During Chronic HIV Infection

The immune response can be defined by the reaction of the immune system to a particular antigen to which it is exposed. In order to understand immune responses against an infectious agent such as human immunodeficiency virus (HIV) and their regulation during the course of chronic HIV infection, we will provide a brief overview of HIV and its proteins and attempt to shed light on this disease process. We will also review the immune system, its components and describe how these components interact at the molecular levels to fight an invading pathogen such as HIV.
