[PDF] antibodies on naive b cells

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.

  • Is IgG present on naive B cells?

    Naive B cells undergo class-switch recombination (CSR) from initially producing membrane-bound IgM and IgD to expressing more effective membrane-bound IgG, IgA, or IgE when encountering antigens.10 déc. 2019

  • Which IgM is present on the naive mature B cell?

    IgM immunoglobulins are produced by plasma cells as part of the body's adaptive humoral immune response against a foreign pathogen. Resting mature yet naive, B lymphocytes express IgM as a transmembrane antigen receptor that functions as part of the B-cell receptor (BCR).

  • What isotype of antibody is only found on naive B cells?

    All naive B cells express cell-surface IgM and IgD, yet IgM makes up less than 10% of the immunoglobulin found in plasma, where the most abundant isotype is IgG. Much of the antibody in plasma has therefore been produced by B cells that have undergone isotype switching.
  • B cells respond to antigens by engagement of their B-cell antigen receptor (BCR) and of coreceptors through which signals from helper T cells or pathogen-associated molecular patterns are delivered.
