The immune system and HIV

The HIV virus attacks white blood cells, which are called T-helper cells or CD4 cells. These are important when it comes to having a healthy immune system as they help us fight off diseases and infections. HIV cannot grow or reproduce on its own. Instead, it makes new copies of itself inside T-helper cells which damages the immune system and gradually weakens our natural defences. This process of T-helper cells multiplying is called the HIV life cycle. How quickly the virus develops depends on how early you are diagnosed, your overall health and how well you take your treatment. It’s important to know that antiretroviral treatment will keep the immune system healthy if taken correctly and therefore prevent AIDS. The HIV life cycle The life cycle of HIV goes through various different steps that can happen over many years. Antiretroviral treatment works by interrupting the cycle and protecting your immune system. There are different drugs offered depending on the particular stage of the HIV life cycle. Understanding the HIV life cycle helps scientists to know how to attack the virus when it is weak and reduce the risk of drugs no longer working (drug resistance). This happens when drugs fail to prevent the virus from multiplying.Best doctors in delhi
