PREPARATION
,Antigen (Ag) -ANSWER✅✅✅Any molecule that can bind specifically to an antibody;
named for its ability to generate antibodies ("anti-body generators").
Antibody (Ab) -ANSWER✅✅✅A molecule with a unique antigen-binding pocket that
binds specifically to its antigen; produced by plasma cells and functions to neutralize
pathogens or mark them for destruction.
Active immunization -ANSWER✅✅✅Immunization with antigen to stimulate the body's
own immune response.
Passive immunization -ANSWER✅✅✅Transfer of pre-existing antibodies to an
unimmunized individual.
ABO blood group antigens -ANSWER✅✅✅Carbohydrate antigens on red blood cells
that determine blood type and transfusion compatibility.
Acute rejection -ANSWER✅✅✅Rapid T cell-mediated immune response against a
transplanted organ occurring days to weeks after transplantation.
Acquired immunodeficiency -ANSWER✅✅✅Impaired immune function due to external
factors such as infections, malnutrition, or therapy.
Activation-induced (cytidine) deaminase (AID) -ANSWER✅✅✅Enzyme required for
somatic hypermutation and class-switch recombination in B cells.
Adaptive immune response -ANSWER✅✅✅Antigen-specific lymphocyte response with
immunological memory generated through clonal selection.
Adjuvant -ANSWER✅✅✅Substance that enhances the immune response to an
antigen.
Adoptive Cell Transfer (ACT) -ANSWER✅✅✅Therapy involving collection,
modification, and reinfusion of immune cells.
Afferent -ANSWER✅✅✅Carrying toward (e.g., afferent lymphatic vessel carries lymph
toward lymph node).
Affinity -ANSWER✅✅✅Strength of binding between two molecules.
Affinity maturation -ANSWER✅✅✅Increase in antibody affinity during immune
response progression.
,Agglutination -ANSWER✅✅✅Clumping of particles/pathogens due to antibody binding.
Allergen -ANSWER✅✅✅Antigen that induces allergic (hypersensitivity) reactions.
Allergic asthma -ANSWER✅✅✅Bronchial constriction due to allergic reaction to
inhaled antigens.
Allergic rhinitis -ANSWER✅✅✅Allergic inflammation of nasal mucosa (hay fever).
Allograft -ANSWER✅✅✅Tissue graft from a genetically different individual of the same
species.
Anaphylactic shock -ANSWER✅✅✅Severe systemic allergic reaction causing
circulatory collapse and airway constriction.
Anaphylatoxin -ANSWER✅✅✅Complement fragments (C3a, C5a) that promote
inflammation.
Anergy -ANSWER✅✅✅Functional inactivation of lymphocytes.
Antibody-dependent cell-mediated cytotoxicity (ADCC) -ANSWER✅✅✅Killing of
antibody-coated cells by immune cells (e.g., NK cells).
Antigen-antibody complexes (immune complexes) -ANSWER✅✅✅Bound groups of
antigens and antibodies.
Antigen-presenting cells (APCs) -ANSWER✅✅✅Cells (dendritic cells, macrophages, B
cells) that process and present antigens to T cells.
Antigen processing -ANSWER✅✅✅Enzymatic breakdown of proteins into peptides for
MHC presentation.
Antigen presentation -ANSWER✅✅✅Display of peptide-MHC complexes to T cells.
Allogenic -ANSWER✅✅✅From the same species.
Allogenic stem cell transplantation -ANSWER✅✅✅Transfer of stem cells from a donor
of the same species.
Antiserum -ANSWER✅✅✅Serum containing antibodies against specific antigens.
Angiogenesis -ANSWER✅✅✅Formation of new blood vessels.
, Antibody repertoire -ANSWER✅✅✅Total diversity of antibodies an individual can
produce.
Apheresis -ANSWER✅✅✅Removal and separation of blood components.
Apoptosis -ANSWER✅✅✅Programmed cell death.
Atopy -ANSWER✅✅✅Genetic predisposition to allergic diseases.
Attenuated virus -ANSWER✅✅✅Weakened virus used in vaccines.
Autoimmune disease -ANSWER✅✅✅Disease caused by immune response against
self-antigens.
Autoimmune regulator (AIRE) -ANSWER✅✅✅Transcription factor promoting central
tolerance.
Autoimmunity -ANSWER✅✅✅Immune response against self tissues.
Autologous -ANSWER✅✅✅From the same individual.
Autoreactivity -ANSWER✅✅✅Immune response directed against self-antigen.
Base excision repair -ANSWER✅✅✅DNA repair process involved in somatic
hypermutation.
Basophils -ANSWER✅✅✅Granulocytes involved in allergic responses and histamine
release.
B cell -ANSWER✅✅✅Lymphocyte with surface immunoglobulin receptor.
Clonal selection (B cells) -ANSWER✅✅✅Process by which antigen-specific B cells
proliferate and differentiate.
β-2 microglobulin -ANSWER✅✅✅Light chain component of MHC class I molecules.
Blood group antigens -ANSWER✅✅✅Surface molecules on RBCs used for blood
typing.
BALT -ANSWER✅✅✅Bronchus-associated lymphoid tissue.
Bone marrow -ANSWER✅✅✅Site of hematopoiesis and B cell development.
