antibodies are produced by what defense substances
Antibodies are proteins produced by specialized immune cells called B lymphocytes. Each B cell produces 1 type of antibody. B cells are so numerous and diverse, that the body can produce a virtually limitless array of antibodies to bind almost anything that we encounter.Antibodies bind to substances and neutralize them, and also help our white blood cells ingest and kill potentially harmful microbes. cells are so numerous and diverse, that the body can produce a virtually limitless array of antibodies to bind almost anything that we encounter. Antibodies bind to substances and neutralize them, and also help our white blood cells ingest and kill potentially harmful microbes. Monoclonal antibodies use the development of specific antibodies (protein molecules produced by the b cells as a primary immune defense), which are directed against antigens (substances that are capable of inducing a specific immune response) located on the surface of tumor cells.onoclonal antibodies use the development of specific antibodies (protein molecules produced by the b cells as a primary immune defense), which are directed against antigens (substances that are capable of inducing a specific immune response) located on the surface of tumor cells. Each antibody binds to a specific antigen; an interaction similar to a lock and key. An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize pathogens such as bacteria and viruses.The antibody recognizes a unique molecule of the harmful agent, called an antigen, via the variable region.hough strictly speaking, an antibody is not the same as an immunoglobulin; B cells can produce two types of immunoglobulins-surface immunoglobulins, which are B cell receptors; and secreted immunoglobulins, which are antibodies. So antibodies are one of two classes of immunoglobulins. Antibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant.The antigen is tagged as an intruder and labeled for destruction by other immune cells.Antibodies protect against substances prior to cell infection. Antibodies are produced by a type of white blood cell called a B cell (B lymphocyte).B cells develop from stem cells in bone marrow. When B cells become activated due to the presence of a particular antigen, they develop into cells called plasma cells.ntibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant. The third line of defense, the immune system, responds in a specific way to particular toxins, microorganisms, aberrant body cells, and other substances marked by foreign molecules. Specific defensive proteins called antibodies are produced by lymphocytes. 2) Non-specific defense.Microbes that penetrate the first line of defense face the second line of defense, which depends mainly on phagocytosis, the ingestion of invading organisms by certain types of white cells.pecific defensive proteins called antibodies are produced by lymphocytes. 2) Non-specific defense.

When an antigen enters the body, it stimulates the immune system to produce antibodies.The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it. Every healthy adult's body has small amounts of thousands of different antibodies. Each one is highly specialized to recognize just one kind of foreign substance. Antigens are chemicals on the surface of a cell. All cells have these. The immune system checks cells and identifies them as self or non-self. Antibodies are proteins produced by certain lymphocytes in response to a specific antigen.B-lymphocytes and T-lymphocytes produce the antibodies. B-lymphocytes become plasma cells which then generate antibodies. T-lymphocytes attack cells which bear antigens they recognize.elper T cells activate B cells that produce antibodies. Supressor T cells slow down and stop the immune response of B and T cells, serving as an off switch for the immune system. Cytotoxic (or killer) T cells destroy body cells infected with a virus or bacteria. Humoral immunity, also called the antibody-mediated beta cellularis immune system, is the aspect of immunity that is mediated by macromolecules (as opposed to cell-mediated immunity) found in extracellular fluids such as secreted antibodies, complement proteins and certain antimicrobial peptides.umoral immunity refers to antibody production and the accessory processes that accompany it, including: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation. Allergen: A foreign substance that causes an allergic reaction in the body. B cells: Cells produced in bone marrow that secrete antibodies. Immune response: The production of antibodies in response to foreign substances in the body.Immunity: The condition of being able to resist the effects of a particular disease.The immune system is the body's natural defense system.)
