  • MHC Polymorphism and Antigen Binding

    • MHC molecules display a molecular fraction called an epitope and mediate interactions of leukocytes with other leukocytes or body cells.
    • MHC molecules display a molecular fraction called an epitope and mediate interactions of leukocytes with other leukocytes or body cells.
    • Human MHC class I and II are also called human leukocyte antigen (HLA).
    • The human leukocyte antigen (HLA) system is the name of the major histocompatibility complex (MHC) in humans.

  • Cells and Organs of the Immune System

    • Leukocytes (white blood cells) are immune system cells involved in defending the body against infectious disease and foreign materials.
    • Five different types of leukocytes exist, all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell.
    • The innate leukocytes include the phagocytes, mast cells, eosinophils, basophils, and natural killer cells.
    • Natural killer cells are leukocytes that attack and destroy tumor cells, or cells that have been infected by viruses.
    • The cells of the adaptive immune system are special types of leukocytes, called lymphocytes .

  • Classes of T Cells

    • In response to antigenic stimulation, helper T cells (characterized by the expression of CD4 marker on their surface) secrete proteins called cytokines, whose function is to stimulate the proliferation and differentiation of the T cells themselves, as well as other cells, including B cells, macrophages, and other leukocytes.

  • Development of the Dual Lymphocyte System

    • The cells of the adaptive immune system are a type of leukocyte, called a lymphocyte.

  • Virus Attachment and Genome Entry

    • For example, HIV infects a limited range of human leukocytes.

  • Urinary Tract Infection (UTI)

    • In complicated cases, it may be useful to confirm the diagnosis via urinalysis, looking for the presence of urinary nitrites, white blood cells (leukocytes), or leukocyte esterase.

  • General Features of Virus Replication

    • For example, HIV can infect only a limited range of human leukocytes.

  • Cytotoxic Autoimmune Reactions

    • HLA-DR is a MHC class II cell surface receptor encoded by the human leukocyte antigen complex on chromosome 6 region 6p21.31.

  • The Roles of Genetics and Gender in Autoimmune Disease
