A lymphocyte is one of the subtypes of a white blood cell in a vertebrate 's immune system. Lymphocytes include natural killer cells which function in cell-mediatedcytotoxic innate immunityT cells for cell-mediatedcytotoxic adaptive immunityand B cells for humoralantibody -driven adaptive immunity. They are the main type of cell found in lymphwhich prompted the name "lymphocyte".
Skip to Content. You will also read general information on surviving the disease. Remember, survival rates depend on several factors.
Mathematical modeling reveals that long-term immunological memory is maintained in a manner that is even more dynamic than previously thought. The immune system contains many different types of cells. Some of these cells can recognize pathogens without ever having encountered them.

Lymphocyte differentiation is set to produce myriad immune effector cells with the ability to respond to multitudinous foreign substances. The uniqueness of this developmental system lies in not only the great diversity of cellular functions that it can generate but also the ability of its differentiation intermediates and mature effector cells to expand upon demand, thereby providing lifelong immunity. Surprisingly, the goals of this developmental system are met by a relatively small group of DNA-binding transcription factors that work in concert to control the timing and magnitude of gene expression and fulfill the demands for cellular specialization, expansion, and maintenance.
Lymphocytetype of white blood cell leukocyte that is of fundamental importance in the immune system because lymphocytes are the cells that determine the specificity of the immune response to infectious microorganisms and other foreign substances. In human adults lymphocytes make up roughly 20 to 40 percent of the total number of white blood cells. They are found in the circulation and also are concentrated in central lymphoid organs and tissues, such as the spleentonsil s, and lymph node s, where the initial immune response is likely to occur.
NCBI Bookshelf. New York: Garland Science; Once lymphocytes have left the central lymphoid tissues, they are carried in the blood to the peripheral lymphoid tissues.
Hematology is the study of blood and the disorders related to it. Blood has many functions, including transporting oxygen, regulating body temperature, and supporting the immune system. The cellular component consists of three major cell types, all of which arise from hematopoietic stem cells located primarily in the bone marrow : red blood cells RBCswhite blood cells WBCsand platelets.
Freitas, Lymphocyte population kinetics during the development of the immune system. We have investigated the kinetic behaviour of LPS reactive B cells during the development of the immune system. Cr LPS non-responder mice we have confirmed that B cell populations obtained from adult donor mice decay rapidly after transfer into adult recipients.
