Ch33 The Immune System

immunity that has memory and occurs after exposure to an antigen either from a pathogen or a vaccination

• adaptive immunity
• autoimmune response
• major histocompatibility class (MHC) I/II molecule
• complement system

protein that is produced by plasma cells after stimulation by an antigen; also known as an immunoglobulin

• antibody
• cell-mediated immune response
• antigen-presenting cell (APC)
• interferon

foreign or "non-self" protein that triggers the immune response

• antigen
• opsonization
• eosinophil
• cross reactivity

immune cell that detects, engulfs, and informs the adaptive immune response about an infection by presenting the processed antigen on the cell surface

• antigen-presenting cell (APC)
• basophil
• humoral immune response
• inflammation

inappropriate immune response to host cells or self-antigens

• autoimmune response
• cytotoxic T lymphocyte (CTL)
• eosinophil
• cross reactivity

lymphocyte that matures in the bone marrow and differentiates into antibody-secreting plasma cells

• B cell
• dendritic cell
• macrophage
• immunodeficiency

leukocyte that releases chemicals usually involved in the inflammatory response

• basophil
• hypersensitivities
• effector cell
• opsonization

adaptive immune response that is carried out by T cells

• cell-mediated immune response
• neutrophil
• complement system
• helper T lymphocyte (TH)

activation of B cells corresponding to one specific BCR variant and the dramatic proliferation of that variant

• clonal selection
• complement system
• immunodeficiency
• lymph

array of approximately 20 soluble proteins of the innate immune system that enhance phagocytosis, bore holes in pathogens, and recruit lymphocytes; enhances the adaptive response when antibodies are produced

• complement system
• autoimmune response
• immunodeficiency
• adaptive immunity
