  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. Lymphocytosis - Wikipedia

    en.wikipedia.org/wiki/Lymphocytosis

    Lymphocytosis is an increase in the number or proportion of lymphocytes in the blood.Absolute lymphocytosis is the condition where there is an increase in the lymphocyte count beyond the normal range while relative lymphocytosis refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range.

  4. Neutrophil to lymphocyte ratio - Wikipedia

    en.wikipedia.org/wiki/Neutrophil_to_lymphocyte_ratio

    The neutrophil to lymphocyte ratio (NLR) reflects systemic inflammation, which plays an important role in the process of treating ischemic strokes.

  5. Tumor-infiltrating lymphocytes - Wikipedia

    en.wikipedia.org/wiki/Tumor-infiltrating_lymphocytes

    They are key to an experimental autologous cell therapy (Contego) for metastatic melanoma. [15] Autologous TIL therapy for metastatic melanoma has broad T cell recognition of both defined and undefined tumor antigens against all human leukocyte antigen (HLA) restrictions.

  6. Human leukocyte antigen - Wikipedia

    en.wikipedia.org/wiki/Human_leukocyte_antigen

    HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1]

  7. Lymphocyte homing receptor - Wikipedia

    en.wikipedia.org/wiki/Lymphocyte_homing_receptor

    Lymphocyte homing receptors are cell adhesion molecules [1] expressed on lymphocyte cell membranes that recognize addressins on target tissues. Lymphocyte homing refers to adhesion of the circulating lymphocytes in blood to specialized endothelial cells within lymphoid organs. [2]

  8. T cell - Wikipedia

    en.wikipedia.org/wiki/T_cell

    T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response.T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface.

  9. T independent antigen (TI) - Wikipedia

    en.wikipedia.org/wiki/T_independent_antigen_(TI)

    T independent antigens elicit antibody production by B lymphocytes without T lymphocyte involvement. There are two distinct subgroups of TI antigens, different in mechanism of activating B lymphocytes: TI-1 antigen, which has an activity that can directly activate B cells and TI-2 antigen, which has highly repetitive structure and causes simultaneous cross-linking of specific B cell receptors ...
