  2. Plasma cell - Wikipedia

    en.wikipedia.org/wiki/Plasma_cell

    Instead, plasma cells are identified through flow cytometry by their additional expression of CD138, CD78, and the Interleukin-6 receptor. In humans, CD27 is a good marker for plasma cells; naïve B cells are CD27−, memory B-cells are CD27+ and plasma cells are CD27++. [5] The surface antigen CD138 (syndecan-1) is expressed at high levels. [6]

  3. 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]

  4. CD19 - Wikipedia

    en.wikipedia.org/wiki/CD19

    CD19 is widely expressed during all phases of B cell development until terminal differentiation into plasma cells. During B cell lymphopoiesis, CD19 surface expression starts during immunoglobulin (Ig) gene rearrangement, which coincides during B lineage commitment from hematopoietic stem cell. [8]

  6. Immunoglobulin class switching - Wikipedia

    en.wikipedia.org/wiki/Immunoglobulin_class_switching

    Mechanism of class-switch recombination that allows isotype switching in activated B cells. Immunoglobulin class switching, also known as isotype switching, isotypic commutation or class-switch recombination (CSR), is a biological mechanism that changes a B cell's production of immunoglobulin from one type to another, such as from the isotype IgM to the isotype IgG. [1]

  7. 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.

  9. B-cell receptor - Wikipedia

    en.wikipedia.org/wiki/B-cell_receptor

    A B-cell receptor includes both CD79 and the immunoglobulin. The plasma membrane of a B cell is indicated by the green phospholipids. The B- cell receptor extends both outside the cell (above the plasma membrane) and inside the cell (below the membrane). The B-cell receptor (BCR) is a transmembrane protein on the surface of a B cell.
