  • How does B-cell activation lead to antibody production?

    Each B cell produces a single species of antibody, each with a unique antigen-binding site. When a naïve or memory B cell is activated by antigen (with the aid of a helper T cell), it proliferates and differentiates into an antibody-secreting effector cell.

  • How are B cells in relation to antibody production?

    There are two main types of B-cells: plasma cells and memory cells. Both types help protect you from infection and disease. Plasma cells: Plasma cells release antibodies in response to antigens. Once a B-cell becomes a mature plasma cell, it can release up to 2,000 antibodies per second.2 jan. 2023

  • What activates B cells to produce antibodies?

    A B cell becomes activated when its receptor recognizes an antigen and binds to it. In most cases, however, B-cell activation is dependent on a second factor mentioned above—stimulation by an activated helper T cell.
  • B cells create antibodies.
    These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection. B cells can also recruit other cells to help destroy an infected cell.
