Human Immunodeficiency Virus (HIV) is a virus that affects the immune system of people making them susceptible to opportunistic diseases. The ability of the immune system of individuals to fight HIV infection depends on T cells and not by how many T cells are produced. The article is important in that it shows the role of T cells in the control of HIV infection. It is also important that HIV has become a disaster to eliminate and has no cure thus, the article states the role of HIV-specific killer T cells to contain viral replication.
The article shows that the presence of T cells is not enough. This is because; individuals who can fight HIV on their own develop killer cells with CD8 receptors, which are effective in killing HIV-infected cells. The points raised are that some individuals can suppress HIV replication with their immune system and they keep the viral load at low levels. In addition, certain versions of HLA-B are associated with the ability to control HIV infection (Walker 2012). The questions raised are;
What is the number of CD4 cells in a healthy person? Why is it difficult to find the cure for HIV?
