  2. Lymphocyte - Wikipedia

    en.wikipedia.org/wiki/Lymphocyte

    A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...

  3. Lymphopoiesis - Wikipedia

    en.wikipedia.org/wiki/Lymphopoiesis

    The inactive B and T cells are so featureless with few cytoplasmic organelles and mostly inactive chromatin that until the 1960s textbooks could describe these cells, now the central focus of immunology, as having no known function! [11] However, T and B lymphocytes are very distinct cell lineages and they ‘grow up’ in different places in ...

  4. Clonal deletion - Wikipedia

    en.wikipedia.org/wiki/Clonal_deletion

    There are millions of B and T lymphocytes within the immune system. As a T or B lymphocyte develops, they can rearrange their genome in order to express a unique antigen that will recognize a specific epitope on a pathogen. [8] [9] There is a large diversity of epitopes recognized and, as a result, it is possible for some B and T lymphocytes to ...

  5. T cell - Wikipedia

    en.wikipedia.org/wiki/T_cell

    Unlike CD8 + killer T cells, the CD4 + helper T (T H) cells function by further activating memory B cells and cytotoxic T cells, which leads to a larger immune response. The specific adaptive immune response regulated by the T H cell depends on its subtype (such as T-helper1, T-helper2, T-helper17, regulatory T-cell), [ 4 ] which is ...

  6. B cell - Wikipedia

    en.wikipedia.org/wiki/B_cell

    B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. [1] They function in the humoral immunity component of the adaptive immune system . [ 1 ] B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors . [ 2 ]

  7. Antigen processing - Wikipedia

    en.wikipedia.org/wiki/Antigen_processing

    The most abundant lymphocytes are: B lymphocytes (often simply called B cells) T lymphocytes (likewise called T cells) B cells are produced in the bone marrow. The precursors of T cells are also produced in the bone marrow but leave the bone marrow and mature in the thymus (which accounts for their designation).

  8. List of immune cells - Wikipedia

    en.wikipedia.org/wiki/List_of_immune_cells

    Killer T cell: Lymphocyte: T cell: T lymphocyte; Lymphocytus T; 8-10 Virus-infected cells; Cancer cells; Recruits and communicates with other types of immune cells [4] [17] Memory T cell: Lymphocyte: T cell: MTC; 8-10 Memorizes the characteristics of the antigens; Triggers an accelerated and robust secondary immune response [4] [18] T helper ...

  9. Immunological memory - Wikipedia

    en.wikipedia.org/wiki/Immunological_memory

    Unlike the naive B cells involved in the primary immune response the memory B cell response is slightly different. The memory B cell has already undergone clonal expansion , differentiation and affinity maturation , so it is able to divide multiple times faster and produce antibodies with much higher affinity (especially IgG ).
