What is a blocking antibody?
Antibodies are an important part of the immune system that counteracts the disease organisms. The blocking antibody is a specific type that works by preventing bacteria or virus from attaching to the host cell. Blocking antibody by connecting to a part of a bacterium or a virus that is used to part of a bacterium or a virus that is used to attach the host cells more difficult or impossible to damage its host.
The antibody is a protein produced by the immune system in response to a foreign attacker such as bacteria and viruses. These attackers, including any substance that evokes the reaction of the immune system, are called antigens . Several types of cells work together to create the right antibody to fight a particular antigen. Any antibody, including blocking antibodies, is specific to antigen, which means it will only work against a specific antigen. Macrophage absorbs invasive bacterium or virus and uses biochemicalÉ processes to divide the cell into smaller units. The main proteins of histocompatibility (MHC) bind to antigenic subunites - parts of the cell that cause an immune response - and bring them to the surface of the macrophage to be handed over to the cells
Protein in t cells, called and t cell receptor (TCR), recognizes MHC proteins produced by macrophages. TCR can only recognize antigens that were bound to MHC protein. Once TCR recognizes antigen, there are several different ways that the cell can act to destroy invasive cells. T cells that help produce antibodies called cells t-helper stimulate B cells to produce antibodies specific to antigen.
B cells produce antibodies by working in conjunction with T-helper cells. When and B the cell is bound to the antigen, it cannot immediately create the right antibody.Instead, it first degrades the antigen and presents it in the T-Helper cell. The T-Helper cell then produces chemicals that stimulates the B cell to produce antibodies specific to this antigen.
In a specific case, the antibody antibody does not cause any visible reaction with the antigen. Instead, it prevents anything else to join the antigen. Thus, the blocking antibody can prevent a harmful organism to infect the host cell, because once the antigen is bound to the antibody, it cannot be bound to anything else.
