And these cytokines not only induce wide blood cell differentiation but they also stimulate the cells of our innate immune system. These are our macrophages, neutrophils, basafils and other wide blood cells of our innate immune system. So we see that by destroying the population of our helper T cells what HIV actually does is it severely weakens not only our adaptive, our acquired immune system but also our innate immune system. And as a result, most individuals infected with HIV die not from the virus itself but from other infections that infect our bodies such as the common cold, pneumonia, the flu or even cancer. And because our body cannot actually defend itself because our immune system is weakened that is why we actually die. So we die because of our body's inability to mount a proper immune response as a result of the Choir Immune Deficiency Syndrome or AIDS.
