Function of CD4 Cells and HIV Infection

There is a huge role of CD4 cells in resisting the various infections and diseases. HIV infection is not exceptional for that reason. The immune system is composed of the CD4 cells. Unfortunately the virus breaks the whole system. The intensity of the virus is so disastrous that it allows different opportunistic infections to assault on the body. The virus does not skip even a single system of the body without the destruction when it converts itself in the AIDS. After developing AIDS a person becomes the house of diseases where almost every infection and diseases takes the advantage of the already damaged system. Function of CD4 cells and HIV infection both are co-related with other as HIV creates the obstacles in its function.

Let us see the co-relation between the Function of CD4 Cells and HIV Infection:

CD4 cells or soldier cells protect the body from the infections and diseases. CD4 cells are also called as T helper cells resist the various infections and the diseases. These cells fight with funnies, bacteria, viruses that are the causes of various infections and diseases. These cells keep on an eye on the invaders. Once the invaders attack on the body they simply fight off with them and destroy them completely. As a result of this a body of a person stays healthy and safe. That is the reason CD4 cells' count is important. If you have more CD4 cells in your body, it means your immune system is stronger.

However, HIV is an exception for the rule as CD4 cells can not resist the infection completely. The reason is that they can not identify the existence of the virus in the body. The virus destroys the immune system step by step and gradually. The steps are described as the stages of HIV infection. As the virus enters in the body it starts reproducing its copies. At the beginning of the HIV infection, these copies are limited as the virus develops slowly. However, it does not mean that a person is not infectious. On the other hand he/she is highly infectious as a virus exists in high level in genital floods. The person can transmit the virus to the others without having any idea. So it is essential to go through a series of HIV tests.

How does HIV damage the immune system?

The process of damaging the cells takes several years. The virus gradually turns into the AIDS. Certain processes need to be crossed for the development of HIV infection. The virus hides in CD4 cells and begins the process of copying itself. As the immune system fails to recognize the existence of virus it develops itself. The declining process of the immune system leads the body to develop AIDS. As the reproduction process of the virus goes on, immune system succumbs to the infection. Eventually, replication of the virus reaches at the culmination. As a result of this opportunistic infections assaults on the weakened immune system. These infections usually can not harm the body because of immune system. However, as the immune system has been weakened by the virus, it is not possible for the immune system to resist these infections.

Why the CD4 count should be higher?

It is good to be have CD4 count between 700 to 1000. Generally, it is fine if your CD4 count is 500. When the CD4 count drops down to below 200, a person is classified as an AIDS patient. When you go to the doctor for having a treatment, he/she checks the CD4 cells' count. It is essential to know about the CD4 cells count for a person. It describes the stage of HIV infection a person is having. It helps the physician to decide the treatment plan for the person. Because of that the further consequences can be controlled.

HIV infection and Health

HIV infected person has to be more careful regarding his/her diet as diet plays vital role in the matter. Having a nutritional diet will make the immune system strong. It will enable the immune system to fight off with the infections. Balance diet will be beneficial for the person. The infected person should have a balanced diet and enough exercise for being healthy.

Function of CD4 Cells and HIV Infection are co-related terms. The main function of CD4 cells is to protect the body from the infections and diseases and HIV infection is not exception for that.
