What are the different monocyte roles?
white blood cells called monocytes are an important part of the body's immune system. It protects the body from microorganisms or pathogens, especially those that can cause malaria, tuberculosis and typhus. They move at high speed in the bloodstream, collect debris or remain that accumulates from the infection. The immune response, made both by lymphocytes derived from the bone marrow (B) and the tymum (T), is also activated by some monocytes. Lymphocytes are white blood cells that form a lymphatic system or the second line of body defense.
The number of monocytes accounts for 5–12% of the total number of white blood cells. The largest white blood cells, this type has a large core that controls cell activities, as well as several granules in the cytoplasm. They are attracted by bacteria and other foreign materials that take and destroy through phagocytosis. Therefore, they are also referred to as phagocytes, a classification that they share with granulocytems, the most abundant of the white blood cells. Fagocytosis concerns the process that the cell takes in large, solid materialch.
However,granulocytes respond faster to the bacterial presence than monocytes. However, monocytes can destroy much more bacteria than granulocytes. Another characteristic of monocytes is that they can break away from blood and survive in other tissues. If this happens, monocyte can become a macrophage, a phagocytic cell without granules in a cytoplasm or dendritic cell, a special cell that has an extension called dendrites. Bone marrow is part where monocytes are produced, although they are also believed to be based on lymphocytes.
macrophages work in the collection of worn cells and activate the immune response. To activate the body's immune response, macrophages absorb pathogens, then carry a substance that is present in pathogens called antigens, for t lymphocytes for identification purposes. After the identification of antigens, B lymphocytes are activated to form antibodies. These natural chemicals of the body do notThey suffer toxins of pathogens and their continuing presence ensures immunity to a number of diseases. The reaction of antibodies against antigens makes it easier to consume pathogens, although it should be noted that not all pathogens can be spent macrophages.
As macrophages, dendritic cells also absorb pathogens that are captured by numerous cell branches. These branches called dendrites are similar to dendrites of nerve cells. However, their functions are not the same. The dendritic cell action also activates T lymphocytes to fulfill their role in identifying antigens.
