What is human cytokin?

Human cytokine is any member of a large class of proteins and peptides that bears signals between the cells of the living organism to control the body's immune response to infection. In addition to their basic importance for the immune system, cytokines also play a role in other biological processes, such as embryo formation. The dividing line between cytokines and hormones is due to their structural similarity of fuzzy. Cytokines come from cells distributed throughout the body, while hormones are primarily produced by specialized glands. Human cytokine has equivalents or close analogs in other vertebrates.

immune systems of people and other vertebrates produce many different types of cytokines that serve different functions in the body's immune response. Different types of human cytokine can supply signals to other cells that direct them to the production of antibodies, regulation of inflammation and attack on viruses, foreign microorganisms and fellow citizens that have been damaged or infected with intruders. Are primarily produced by leukocyteY, also known as white blood cells.

interferons are a type of cytokine important in cellular reactions to infection. When the type of lymphocytes called the auxiliary cell T identifies in the body of a foreign intruder, it releases interferons that signal other immune cells, such macrophages, cytotoxic T cells (or killer t cells) and natural killer cells (NK). These cells then protect the body by attacking and destruction of pathogens, as well as colleagues in bodies that are infected or broken, such as cells in tumors. The cells dying of viral infection also release interferons that warn other cells of danger, causing other enzymes and proteins that disrupt the viral reproduction.

cytokines that are able to chemically affect the movement of other cells, procedural calls of chemotaxis, are called chemokins. Chemokines help the body's immune response by leading the cells of the immune system,Where they are needed. Some chemokins are produced in the normal course of the organism's activity to regulate the movements of white blood cells as they guard the body. Others are produced in large quantities when infection is detected to cause white blood cells to a place of potential danger.

The factors of tumor necrosis (TNF) are cytokines that kill their own cells of the body. They are discharged to destroy cells that have been taken over by viruses or become cancerous. TNF also participates in the inflammation process.

Many types of human cytokine are part of the interleukins group, which has a diverse range of features. Different types of interleukin are commonly referred to by IL and number. Some interleukins indicate for the production of antibodies or activation of immune cells, such as macrophages to destroy pathogens, while they tend to be important for triggering and regulating immune responses such as inflammation and fever. Interleukins are also important in immunological memory, the ability of the immune system to adapt to efficientMoreover, the fighting with the pathogens she has encountered in the past.
