  • Adaptive Immunity
    A defense system with components that adapt over time, providing specific protection against particular pathogens.
  • Cell-Mediated Immunity
    A branch of defense targeting intracellular pathogens using T cells and their receptors.
  • Humoral Immunity
    A branch of defense targeting extracellular pathogens using B cells and antibodies.
  • T Cell
    A lymphocyte developing in the thymus, crucial for recognizing and eliminating infected host cells.
  • B Cell
    A lymphocyte maturing in bone marrow, responsible for producing antibodies against specific antigens.
  • Antigen
    A foreign molecule capable of triggering a specific immune response by lymphocytes.
  • Antibody
    A protein secreted by plasma cells that binds specifically to antigens, aiding in their neutralization.
  • Primary Lymphoid Organ
    A site where immature lymphocytes develop into naive forms, such as the thymus and bone marrow.
  • Secondary Lymphoid Organ
    A site where naive lymphocytes encounter antigens and become activated, including lymph nodes and spleen.
  • Naive Lymphocyte
    A fully developed but inactive T or B cell that has not yet encountered its specific antigen.
  • Plasma Cell
    A differentiated B cell specialized in secreting large amounts of antibodies.
  • Memory Cell
    A long-lived lymphocyte capable of mounting a rapid response upon re-exposure to its specific antigen.
  • T Cell Receptor
    A membrane protein on T cells that recognizes specific antigens presented by other cells.
  • B Cell Receptor
    A membrane-bound immunoglobulin on B cells that binds specific antigens, initiating activation.
  • Antigen-Presenting Cell
    A cell, such as a dendritic cell, that displays antigens to T cells, initiating their activation.
