What are the auxiliary cells T?
Help cells are important for the reaction of the human immune system. These cells play a decisive role in identifying infectious agents in the body and then signaling other cells to go to defense of the body. Because T auxiliary cells are usually the first to recognize a virus or bacteria, are often referred to as the first respondents. However, they do not destroy bacteria or viruses themselves. Interestingly, some infections such as human immunodeficiency virus (HIV) are attached to these cells and disrupt their ability to send other cells to work.
One type of cell that is critical in the reaction of the immune system is the auxiliary cell T. This type of cell moves by the body of man in an effort to locate viruses, bacteria or other antigens, which are substances that cause human immune system to react and prevent the body. Help cells do this by interacting with substances that attack and pose a threat to the body.
When the auxiliary cellular cell with antigen comes in two different ways. After contactThe antigen begins a process called cell division. Cell division creates more T cells, resulting in the first respondents to inform other cells of immune response about the problem in the body. T auxiliary cells also release substances called lymphokins and chemokins. Both substances are used to alert other cells of the immune response about the presence of a bacterium, virus or other infectious agent.
Unfortunately, there are some antigens that disrupt the work of the T -Auxiliary cells. One example is HIV. When a person has HIV, the virus actually connects to the auxiliary cells T and destroys them. As a result, auxiliary cells T cannot indicate other cells to fight the virus, and the immune system of the affected person is crippled.
t auxiliary cell T is unable to destroy infection agents in itself, but its work is very important for other t cells and macrophages that are a type of white blood cells that consumeIt eats foreign attackers. The T auxiliary cell stimulates these cells to get into action to destroy infections. These cells also work to ensure that B cells begin to generate antibodies against infection. Antibodies are special types of proteins that connect to a part of the antigen. Once they do, they are able to block the effects of antigen.
