These hormones are responsible for regulating the immune system. After a virus is destroyed, regulatory t cells reduce the activity levels of B lymphocytes and other T cells by releasing their own set of lymphokines, called suppressor factors. The immune system is a formidable system, consisting of multiple intricate parts. These parts

There are two types of adaptive system reponses: humoral and cell meditated. In the humoral immune response proteins, which can stick and destroy antigens appear in the blood and other body fluids. Humoral immune responses resist invaders that act outside of cells such as bacteria or toxins. During cell meditated immune responses cells that can destroy other cells become active. Their destructive activity is limited to cells that are either infected with or producing a specific antigen.
The innate includes barriers like the skin and antibacterial enzymes within tears. The adaptive is based on specialized white blood cells which are lymphocytes and they respond to invasions by micro-organisms. Antibodies are chemicals produced by B cells, they circulate in the blood that attacks disease and causes organisms, T cells attack organisms head on, and these cells can memorize earlier infections and therefore can act fast to avoid further attacks. The defence of the immune system helps to provide protection against infectious disease as well as some malfunctions of the internal body. If the infectious organism splits the skin or maybe one that is not killed off by chemicals, for example the enzymes found in tears or the saliva, the immune and inflammatory response come into action.
If the antigens do manage to enter the body, then your immune system will try to detect the virus and abolish it before it begins to spread. 3. If the virus does reproduce and begins to cause problems, your immune system is then responsible for eliminating it. The most important part of the immune system is the white blood cells, which are also known as leucocytes. The most important type of white blood cell is the lymphocyte.
Once HIV enters the body, it will infect the CD4 cells and begin to use those cells as its own “HIV factory.” HIV will therefore begin to destroy your immune system leaving you susceptible to opportunistic diseases. HIV targets your immune system... What does HIV infect and how? HIV affects your immune system. Your immune system can be thought of as your body’s defense line! In which, you have millions of 'soldiers' (T-helper cells) helping you ward off almost any foreign invaders.
Systematic Lupus Erythematosus (SLE) is a very serious and mysterious disease affecting the immune system. The immune system is designed to protect against foreign substances such as viruses, bacteria, and germs that have infiltrated the body. The immune system has an innate component and an adaptive ability that allows it to produce cells specially designed to destroy foreign or “non-self” substances. The adaptive immune system has two main cells, B cells and T cells. There are different types of T cells, cytotoxic, helper, regulatory, and natural killer T cells.
This complex binds to the helper T cell receptors and unfolds itself to facilitate the fusion of their membranes. HIV enters the capsule releasing two RNA strands and three essential enzymes which were surrounded by an envelope. HIV is unable replicate on its own and instead leverages on the machinery of the host cell to produce new viral particles. Once the virus has infected a T cell, integrase(protein complex) transcribes its RNA into double helix DNA copy by means of viral enzyme reverse transcriptase. Reverse transcriptase lacks it’s ‘filtering’ function that other DNA synthesizing have, mutations arise as it replicates and handicap the immune system’s ability to fight the virus.
Human beings will always obtain viruses that try to attack their immune system, but no other virus is as deadly at doing so as the AIDS virus. AIDS is derived from its earlier version known as HIV, once a healthy body acquires HIV it is prone to advancing towards the more deadly version of the virus, AIDS. Viruses are one of the key divisions of minuscule agents which trigger transferable disease. To be put into simple terms, viruses are organisms which contain an inherited operator that permits them to take control of the regular performance of the cells they infect. After a virus has gained control of the cells, it influences those same cells to make new imitations of the virus.
HIV Treatments and Reducing Drug Resistance Abstract HIV is a retrovirus that will constantly attack human’s immune system once an individual is infected and will eventually develop to AIDS, often a deadly sexually transmitted disease. Currently, there are different kinds of antiretroviral treatments available for patients who are tested to be HIV positive as well as patients with AIDS. HIV can easily develop resistance to its treatment through mutation each generation, which leads to ineffectiveness in treatment. The only way to continue to fight off HIV is to change treatment that is still available. Patients have to cooperate with experienced doctors by adhering to their professional recommendations, while doctors are responsible for closely monitoring the patient’s conditions through test results and their body’s response to treatment, as well as helping them to live healthily without serious damage to their immune system over a long period of time.
