  2. Reactive lymphocyte - Wikipedia

    en.wikipedia.org/wiki/Reactive_lymphocyte

    Reactive lymphocyte surrounded by red blood cells. In immunology, reactive lymphocytes, variant lymphocytes, atypical lymphocytes, Downey cells or Türk cells are cytotoxic (CD8 +) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape.

  3. Epstein–Barr virus–associated lymphoproliferative diseases (also abbreviated EBV-associated lymphoproliferative diseases or EBV+ LPD) are a group of disorders in which one or more types of lymphoid cells (a type of white blood cell), i.e. B cells, T cells, NK cells, and histiocytic-dendritic cells, are infected with the Epstein–Barr virus (EBV).

  4. White blood cell differential - Wikipedia

    en.wikipedia.org/wiki/White_blood_cell_differential

    A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...

  5. Lymphoproliferative disorders - Wikipedia

    en.wikipedia.org/wiki/Lymphoproliferative_disorders

    Lymphoproliferative disorders (LPDs) refer to a specific class of diagnoses, comprising a group of several conditions, in which lymphocytes are produced in excessive quantities. These disorders primarily present in patients who have a compromised immune system .

  6. List of primary immunodeficiencies - Wikipedia

    In these disorders both T lymphocytes and often B lymphocytes, regulators of adaptive immunity, are dysfunctional or decreased in number. The main members are various types of severe combined immunodeficiency (SCID). [7] T-/B+ SCID (T cells predominantly absent): γc deficiency

    Human Cell Atlas; Content; Description: The Human Cell Atlas is a global consortium that is creating detailed maps of the cells in the human body to transform understanding of health and disease. Organisms: Human: Contact; Primary citation: Regev, Aviv; et al. (Human Cell Atlas Organizing Committee) (2018). "The Human Cell Atlas White Paper".

  8. 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 ...

  9. Hodgkin lymphoma - Wikipedia

    en.wikipedia.org/wiki/Hodgkin_lymphoma

    Lymphocyte depleted: Is a rare subtype, composed of large numbers of often pleomorphic RS cells with only few reactive lymphocytes which may easily be confused with diffuse large cell lymphoma. Many cases previously classified within this category would now be reclassified under anaplastic large cell lymphoma. [29] C81.3: M9653/3: Unspecified ...
