  2. B cell - Wikipedia

    en.wikipedia.org/wiki/B_cell

    B cell activation: from immature B cell to plasma cell or memory B cell Basic B cell function: bind to an antigen, receive help from a cognate helper T cell, and differentiate into a plasma cell that secretes large numbers of antibodies. B cell activation occurs in the secondary lymphoid organs (SLOs), such as the spleen and lymph nodes. [1]

  3. Memory B cell - Wikipedia

    en.wikipedia.org/wiki/Memory_B_cell

    Differentiation of memory B cells into plasma cells is far faster than differentiation by naïve B cells, which allows memory B cells to produce a more efficient secondary immune response. [4] The efficiency and accumulation of the memory B cell response is the foundation for vaccines and booster shots.

  4. Plasma cell - Wikipedia

    en.wikipedia.org/wiki/Plasma_cell

    Plasma cells, also called plasma B cells or effector B cells, are white blood cells that originate in the lymphoid organs as B cells [1] [2] and secrete large quantities of proteins called antibodies in response to being presented specific substances called antigens.

    Cell Biology in "The Biology Project" of University of Arizona. Centre of the Cell online; The Image & Video Library of The American Society for Cell Biology Archived 2011-06-10 at the Wayback Machine, a collection of peer-reviewed still images, video clips and digital books that illustrate the structure, function and biology of the cell.

  6. Clone (B-cell) - Wikipedia

    en.wikipedia.org/wiki/Clone_(B-cell)

    The process of immunological B-cell maturation involves transformation from an undifferentiated B cell to one that secretes antibodies with particular specificity. [1] This differentiation and activation of the B cell occurs most rapidly after exposure to antigen by antigen-presenting cells in the reticuloendothelial system, and under modulation by T cells, and is closely intertwined with ...

  7. Epitope - Wikipedia

    en.wikipedia.org/wiki/Epitope

    The part of the antigen that immunoglobulin or antibodies bind to is called a B-cell epitope. [11] B cell epitopes can be divided into two groups: conformational or linear. [11] B cell epitopes are mainly conformational. [12] [13] There are additional epitope types when the quaternary structure is considered. [13]

  8. Peripheral blood mononuclear cell - Wikipedia

    en.wikipedia.org/wiki/Peripheral_blood...

    A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round nucleus. [1] These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei. In humans, lymphocytes make up ...

  9. Somatic hypermutation - Wikipedia

    en.wikipedia.org/wiki/Somatic_hypermutation

    Somatic hypermutation (or SHM) is a cellular mechanism by which the immune system adapts to the new foreign elements that confront it (e.g. microbes).A major component of the process of affinity maturation, SHM diversifies B cell receptors used to recognize foreign elements and allows the immune system to adapt its response to new threats during the lifetime of an organism.
