Future Solutions to HIV AIDS :: Biology Disease

Introduction to human immunodeficiency virusWhat is human immunodeficiency virus?First Things First What is HIV? The Human Immunodeficiency Virus (HIV) is one of the most equivocal viruses that the medical world has to experience. We use the word evasive because HIV targets the CD4 cells (T-helper cells), which are the exact cells that are employ to protect your body against diseases. one time HIV enters the body, it bequeath infect the CD4 cells and initiate to use those cells as its own HIV factory. HIV will therefore begin to destroy your immune system leaving you pliable to opportunistic diseases.HIV targets your immune system...What does HIV infect and how? HIV affects your immune system. Your immune system evict be thought of as your bodys defense business concern In which, you have millions of soldiers (T-helper cells) helping you ward off almost all unusual invaders. Now, it is important to note that just like in a army defense air travel, your body also has diffe rent levels of protection.Introduction to HIV Cont.Your scrape is the for the first time line of defense... First line of defense the skino Your skin is an amazing organ, which helps you ward off invaders from the outside. Special cells called Dendritic cells and macrophages are white line cells that try to fight off infection forrader it becomes a major problem.T-Cells of the humoral immune response are the second line of defense... Second line of defense T-Cellso Once a virus has invaded the body, T-Cells (CD4 cells) relay signals to the rest of the immune system, which causes the immune system to activate by sending out the reinforcements. TheseT-killer cells (CD8 cells) do exactly what the name suggests, they kill almost any foreign invader, through apoptosis or programmed cell death.Other CD4 activated cells are part of your bodys line of defenses... Other Cells activated by CD4 Cellso B-Cells- Once activated, B-cells / Plasma cells begin producing antibodies against a viru so Natural Killer Cells (NK)- Help your body by destroying infected cells Introduction to HIV Cont.All viruses moldiness be able to bind to a cell in order to enter it. In the object lesson of HIV, the virus has a cell membrane with introduce viral proteins that enables it to do so, but this works only when it binds with two specific receptors. One is called the main receptor, and the different a coreceptor. There are two types of HIV M-tropic and T-tropic. The M-tropic variant targets macrophages while the T-tropic variant targets the T cells.Future Solutions to HIV AIDS Biology DiseaseIntroduction to HIVWhat is HIV?First Things First What is HIV?
