Cellular and Molecular Immunology
Innate Immunity - Answer- Protection against infection that relies on mechanisms
that exist before infection, are capable of a rapid response to microbes, and react in
essentially the same way to repeated infection
Adaptive Immunity - Answer- Form of immunity that is mediated by lymphocytes and
stimulated by previous exposure to infectious agents; also known as acquired
immunity
Cytokines - Answer- Proteins that are produced and secreted by many different cell
types and mediate inflammatory and immune reactions
Chemokines - Answer- Large subset of structurally related cytokines that regulate
cell migration and movement
Humoral Immunity - Answer- Type of adaptive immune response mediated by
antibodies produced by B lymphocytes
Effector Mechanisms - Answer- Antibodies are specialized and may activate different
mechanisms to combat microbes
Cell-Mediated Immunity - Answer- Adaptive immunity mediated by T lymphocytes
Active Immunity - Answer- Immunity induced by exposure to a foreign antigen
Passive Immunity - Answer- Immunity conferred on an individual by transferring
serum or lymphocytes from a specifically immunized individual
Immunogens - Answer- Substances that stimulate immune responses; antigens
Opsonization - Answer- Process by which an immune serum enhances the
phagocytosis of bacteria by coating the bacteria
Cardinal features of Adaptive Immunity - Answer- Specificity and diversity, memory,
clonal expansion, specialization, contraction and homeostasis, non-reactivity to self
Determinants/Epitopes - Answer- Parts of antigens that are specifically recognized
by individual lymphocytes
Autoimmune Disease - Answer- Disorder caused by abnormalities in the induction or
maintenance of self-tolerance, which leads to immune responses against self-
antigens
Principal Cells of the Adaptive Immune System - Answer- Lymphocytes, antigen-
presenting cells, and effector cells
