تعريف lymphocytes في الإنجليزية الإنجليزية القاموس.
a type of white blood cells which are the most important cells in the immune system [ Top ]
Small white blood cells that help the body defend itself against infection These cells are produced in bone marrow and develop into plasma cells, which produce antibodies Also known as B cells
Type of white blood cell, found in blood, lymph nodes, spleen, and bone marrow, that forms the immune system that guards individuals against attack by foreign tissue, viruses, and most microorganisms
White blood cells formed in the body's lymphoid tissue The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules Most lymphocytes can be classified as either T or B (with subpopulations of each); those with characteristics of neither major class are called null cells
Small white blood cells that are important to the immune system A decline in lymphocyte function with advancing age is being studied for insights into aging and disease
Small white cells, normally present in the blood and in lymphoid tissue, that bear the major responsibility for carrying out the functions of the immune System There are two major forms of lymphocytes, B-cells and T-cells, which have distinct though related functions in generating an immune response
20-35% of leukocytes - Lymphocytes are manufactured in the lymph tissues, and depending on whether they have differentiated during fetal development in the bone marrow as B cells or in the thymus as T cells, they perform specific roles, reacting to specific antigens, throughout life The process of differentiation is a time when each lymphocyte receives cell surface markers, which ensure that it will react against one and only one kind of foreign antigen; at the same time each lymphocyte learns not to react to the body's own cells Millions of such B and T lymphocytes are "trained" during fetal development When an individual comes in contact with an antigen and the antigen attaches to B and T lymphocytes that have the antigen's cell surface markers, these lymphocytes becomes activated
A type of white blood cell that is primarily responsible for the immune response; includes T cells and B cells
Cells of the immune system that respond specifically to foreign antigens There are two classes of lymphocytes: B-lymphocytes (B-cells) and T-lymphocytes (T-cells) They are found in blood, lymph, and lymphoid tissues B-cells become memory or plasma cells T-cells differentiate into several types: helper (CD4 T-cells); suppressor (CD4 and CD8 T-cells); cytotoxic (CD4 and CD8 T-cells); and memory (CD4 and CD8-T-cells)
(LIM-fo-sites): White blood cells Lymphocytes have a number of roles in the immune system, including the production of antibodies and other substances that fight infection and other diseases
part of the lymphatic system; white blood cells that fight infection and disease
Small white blood cells produced in the lymphoid organs and paramount in the immune defenses (Read about "The Lymph System")
Any of the nearly colorless cells formed in lymphoid tissue, as in the lymph nodes, spleen, thymus, and tonsils, constituting between 22 and 28 percent of all white blood cells in the blood of a normal adult human being They function in the development of immunity and include two specific types,B cells and T cells
Small white blood cells produced in the lymphoid organs and paramount in the immune defenses
type of cell involved in immune response Includes B cells which develop in the bone marrow and produce antibodies and T cells which differentiate in the thymus and are essential for the control and development of immune response
White blood cells that kill viruses and defend against the invasion of foreign material
A type of white blood cell that is the essential cell type in the body’s immune system There are three major types of lymphocytes: B lymphocytes that produce antibodies to help combat infectious agents like bacteria, viruses and fungi; T lymphocytes that have several functions, including assisting B lymphocytes to make antibodies, and natural killer (NK) cells that can attack virus-infected cells or tumor cells
A type of white blood cell or leukocyte that occurs in two forms; B-lymphocytes, which produce antibodies in the humoral immune response, and T-lymphocytes, which participates in the cell-mediated immune response
White blood cells that mature and reside in the lymphoid organs and are responsible for the acquired immune response (see Immune System) The two major types of lymphocytes are T-cells and B-cells
A cell found in the blood and in lymphoid organs such as lymph nodes, tonsil and spleen that plays a central role in the functioning of the immune system
A type of blood cell Specifically, a granulocytic leukocyte (white blood cell) that normally makes up 25 percent of the total white blood cell count but increases in the presence of infection Lymphocytes occur in two forms: B cells, the chief agents of the humoral immune system, which recognize specific antigens and produce antibodies against them; and T cells, the agents of the cell-mediated immune system, which secrete immunologically active compounds and assist B cells in their function
A lymphocyte is any of a group of white blood cells of crucial importance to the adaptive part of the body's immune system The adaptive portion of the immune system mounts a tailor-made defense when dangerous invading organisms penetrate the body's general defenses
(LIM-fo-site): A type of white blood cell that has a number of roles in the immune system Some lymphocytes act as tumor-killing cells Other lymphocytes produce antibodies or other substances that fight cancer, infection, and other diseases The main types of lymphocytes are T cells, B cells, and natural killer (NK) cells
leukocyte with a large round nucleus and usually a small cytoplasm Specialized types of lymphocytes have enlarged cytoplasms and produce antibodies Other specialized lymphocytes are important in cellular immune responses
A type of leukocyte found in the blood, lymph nodes and certain organs Lymphocytes are continuously made in the bone marrow (see also B lymphocytes and T lymphocytes)
A white blood cell that is important in the body's immune response Because they contain nuclei, lymphocytes serve as an easily accessible source for genomic DNA Source : PhRMA Genomics
A variety of white blood cells (immune cells), that are formed in bone marrow and the thymus These cells congregate in the lymph nodes and other organs, and travel throughout the body in lymph fluid or the bloodstream
a leukocyte of blood, bone marrow and lymphatic tissue Lymphocytes play a major role in both cellular and humoral immunity, and thus several different functional and morphologic types must be recognized, i e the small, large, B-, and T-lymphocytes, with further morphologic distinction being made among the B-lymphocytes and functional distinction among T-lymphocytes 1
Lymphocytes are a variety of white blood cells present in blood, lymph nodes, spleen, thymus gland, gut wall and bone marrow Important to the immune system, they produce circulating antibodies and T-lymphocytes, which are primarily responsible for cell-mediated immunity and can differentiate into helper, killer or suppressor cells
Type of white blood cell Responsible for the secretion of antibodies and the phagocytosis of foreign substances 2 deviants of it, the T-cells and B-cells
Type of leukocyte fundamental to the immune system, regulating and participating in acquired immunity. Each has receptor molecules on its surface that bind to a specific antigen. The two primary types, B cells and T cells, originate from stem cells in bone marrow and travel to lymphoid tissues. When a B cell binds to an antigen, it multiplies to form a clone of identical cells. Some of these, acted on by helper T cells, differentiate into plasma cells that produce antibodies against the antigen. Others (memory cells) multiply, providing long-term immunity to the antigen
Any of a group of white blood cells, of crucial importance to the immune system, which defends the body against dangerous invading organisms The principle types are B-lymphocytes and T-lymphocytes (also referred to as B-cells and T-cells respectively)
any of a group of white blood cells of crucial importance to the adaptive (humoral) part of the body's immune system The adaptive portion of the immune system mounts a tailor-made defense when dangerous invading organisms penetrate the body's general defenses
a type of white blood cell produced in the lymphoid organs that is primarily responsible for immune responses Present in the blood, lymph and lymphoid tissues (See also B cell and T cell )
A variety of white blood cells (leucocyte) present in the lymph nodes, spleen, thymus gland, gut wall and bone marrow There are normally 1 5 - 4 9 x 106 lymphocytes per litre of blood They are involved in immunity and can be divided into B-lymphocytes (B-cells), which produce circulating antibodies and T-lymphocytes (T-cells) (see below)
A small white blood cell that plays a major role in defending the body against disease There are two main types of lymphocytes: B cells, which make antibodies that attack bacteria and toxins, and T cells, which attack body cells themselves when they have been taken over by viruses or become cancerous 1
