IgA
immunoglobulin in secretions of the body and acts as first line of defense in MM
IgD
immunoglobulin on surface ob B-lymphocytes & serum, function unknown
IgE
immunoglobulin in skin, lungs & MM, plays a role in allergic reactions and parasites
IgG
most abundant immunoglobulin produced in response to antigens (only one that can cross placenta)
IgM
first immunoglobulin produced in immune response, produced in response to antigens
B-lymphocytes
activated by binding to antigens then differentiate to plasma cells that produce immunoglobulins
T-lymphocytes
don’t produce antibodies but attack antigens directly, proliferate in presence of antigens to make T-cells
Helper T-cells
stimulate antibody production from B-lymphocytes and stimulate cytotoxic T-cells
Cytotoxic T-cells
directly attack and destroy the antigen
Suppressor T-cells
deactivate or suppress the B-lymphs and T-lymphs when they’re no longer needed
Memory T-cells
initiate a quicker immune response in the future due to a previous encounter w/ the same antigen (populations are dedicated to one antigen)
Acquired immunity
formation of antibodies after exposure to an antigen
Antibody (Ab)
proteins produced by WBCs in response to antigens
Antigen (Ag)
foreign substance (protein) that stimulates the production of antibodies
Histiocyte
macrophage, named based on tissue location
Immunity
body’s ability to resist organisms and toxin; immune response
Immunoglobulins
antibodies (gamma globulins) produced by plasma cells
Interstitial fluid
fluid in the spaces between cells; extracellular fluid in tissues
Lymph
watery fluid found in lymphatic vessels
Lymph capillaries
tiniest lymphatic vessels
Lymph node
stationary, bean-shaped structure along lymphatic vessels
Lymph vessels
vessels that carry lymph throughout the body
Macrophages
monocytes that migrate from the blood to the tissue; large phagocytes
Spleen
organ in the cranial abdomen that stores, produces, and destroys blood cells
Thymus gland
organ in the cranial mediastinum that produces and stores lymphocytes
Allergen
substance that causes a specific hypersensitivity
Allergy
abnormal hypersensitivity to an antigen
Anaphylaxis
exaggerated hypersensitivity to a foreign substance; live threatening
Autoimmune disease
disease in which the body makes antibodies against its own good cells and tissues
Carrier
an animal that harbors a disease w/o displaying signs of infection, but can still transmit it to others
Edema
excess fluid (interstitial fluid) in tissues
ELISA
Enzyme-linked immunosorbent assay
test to detect presence of antibodies or antigens in a pt sample
Feline infectious peritonitis (FIP)
disease coused by a coronavirus in cats
Feline immunodeficiency virus (FIV)
retrovirus causing immunosuppession; aka feline AIDS
Feline leukemia virus (FeLV)
retrovirus that causes leukocytosis, immunosuppression, and lymphoma; passed through saliva and excretions
Hypersplenism
condition marked by splenomegaly and excessive cell destruction causing anemia, leukopenia, and thrombocytopenia
Immunofluorescent antibody test (IFA)
test used to detect antigens or antibodies using fluorescent dye
Immunosuppression
impaired immune response, aka immunocompromised
Lymphoma
malignant tumor of lymphoid tissue; aka lymphosarcoma
Opportunistic
organism which is normally nonpathogenic that becomes pathogenic in certain conditions
Remission
symptoms lessen and the patient feels better
Relapse
symptoms return after an apparent recovery
Resistant
doesn’t easily affect; not susceptible
Retrovirus
RNA virus that multiplies by using host’s DNA
Susceptible
easily affected; lacking resistance
Toxin
a poison
Vaccine
suspension containing a killed or weakened microorganism given via injection to induce immunity
Vaccination
administration of a suspension containing a killed or weakened microorganism to induce immunity; aka immunization
Zoonotic
disease capable of being transmitted from animals to humans
