This process begins in the bone marrow, but goes on to mature in the lymphoid tissues of the spleen, lymph nodes, and thymus gland. Collectively, lymphocytes and monocytes are known as agranulocytes. Lymphocytes constitute 25-38 of the total white blood cells (wbcs). Memory cells respond to antigens more rapidly than naive t cells. Upon reexposure to a pathogen, memory cells engage in the t cell recall response, destroying the pathogen quickly. The action of memory cells is the reason why we can get some diseases more than once. Neutrophils, eosinophils, and basophils are also known as granulocytes since they contain granules that can digest microorganisms. Lymphocytes and monocytes are known as agranulocytes since they lack granules in their cytoplasm. This article will give a basic overview of the 5 main types of white blood cells in overview. More detailed information will be available in separate articles.   during inflammation, ly-6c monocytes give rise to monocyte-derived dcs, e. Tnf and inos-producing dendritic cells (tipdc), inflammatory macrophages, and may contribute to myeloid-derived suppressor cells (mdsc) associated with tumors. They are also suspected to contribute to microglia and langerhans cells in selected experimental conditions. Memory cells respond to antigens more rapidly than naive t cells. Upon preexposure to a pathogen, memory cells engage in the t cell recall response, destroying the pathogen quickly. 4the action of memory cells is the reason why we can get some diseases more than once.   the main difference between monocytes and lymphocytes is that the monocytes are responsible for the destruction of pathogens by phagocytosis whereas the lymphocytes are responsible for triggering a specific immune response. Furthermore, monocytes can invade tissues to transform into macrophages or dendritic cells while lymphocytes occur in the circulation.   lymphocytes are white blood cells that are also one of the bodys main types of immune cells. They are made in the bone marrow and found in the blood and lymph tissue. Il-15 is produced by a wide variety of tissues in response to inflammatory stimuli. We examined the effect of il-15 in supporting the maturation of monocytes to dendritic cells in ex vivo culture. Il-15 transformed cd14 monocytes to mature dendritic cells. These dendritic cells were similar to those obtained from monocyte cultures treated with a combination of the cytokines gm-csf, il-4 and.
