exam 2- lecture 1 Flashcards
dry eyes
xeropthalmia
this is a lab test to determine the level of a specific antibody in the blood
antibody titer
disease characterized by the formation of granulomas
granulomatous disease
disease characterized by injury of ones own tissues caused by a cell mediated or humoral response
autoimmune disease
these occur as a result of part of an individuals own body becomes antigens
autoimmune disease
stimulates WBC’s population growth
interleukins
dry mouth
xerostomia
this renders the antigen inactive
antigen-antibody complex
administered y injection
parenteral
immunity predominated by antibodies
humoral immunity
what is it called when antibody combines with an antigen?
immune complex
what are the specific immunoglobulins circulating in the blood serum?
IgG, IgM, IgE, IgA, IgD (gamed)
itching
pruritis
these produce a specific antibody needed to fight the antigen. They also consist of immunoglobulins, immune complex
plasma cell
antiviral actitives
interferon
what do lymphocytes produce and what are their functions?
lymphokines
change monocytes to macrophages
inhibit migration of macrophages so they stay in needed area
activate macrophages
enhance ability of macrophages to destroy foreign cells (phagocytosis)
B cell; lymphatic tissue that matures into plasma cells which produce antibodies
B lymphocyte
type of immunopathologic condition that involves deficiency in number, function, or interrelationships of the involved WBC’s and their products- AIDS
Immunodeficiency
these are the primary WBC’s involved in immune response, recognize/respond to antigens
NK cell-viral infections
Lymphocytes
protein molecule (immunoglobin) produced by plasma cells and reacts with a specific antigen
antibody
this defends the body against injury, particularly from foreign substances such as microorganisms
immune response
these travel to the thymus
T-Lymphocytes
the superficial layer of epithelium sloughs off when firm, sliding manual pressure is applied
Nicolskys sign
a hypersensitive state acquired through exposure to an allergen
allergy
What cells are involved in the immune response?
B lymphocytes (B cells)-eosinophils T lymphocytes (T cells)-Mast cells Macrophages- Natural Killer (NK) cells
what are the types of immunity?
active and passive
dissolution of intercellular bridges of the prickle cell layer of epithelium
acantholysis
protein (IgM) that is detected in serum associated with rheumatoid arthritis
Rheumatoid factor
lymph organ in chest that produces T lymphocytes
thymus
these increase the functioning of B lymphocytes and enhances the antibody response
T helper cells
these are foreign substances against which the immune system defends the body, mainly proteins, often microorganisms and their toxins
antigens
combo of antibody and antigen
immune complex
antibody that reacts against an antigenic constituent of a persons own body
autoantibody
antibody combines with an antigen bound to the surface of tissue cells, incompatible blood transfusions, Rhesus Incompatibility (RH), ex: autoimmune hemolytic anemia
type II (Cytotoxic)
what are the different types of T lymphocytes?
T- Helper cells
T- suppressor cells
immune complexes are formed between microorganisms and antibody in circulating blood, causes phagocytosis/death of the neutrophils with the release of lysosomal enzymes causing tissue destruction..ex: systemic lupus erythematous
type III (Immune complex)
state of altered reactivity whereby the body reacts to the foreign agents with exaggerated immune response
hypersensitivity
large mononuclear phagocyte that assists in an immune response
macrophage
tissue composed of lymphocytes and a meshwork of CT
lymphoid tissue
infection (herpes) that involves the distal phalanx of a finger
whitlow
immunity predominated by T lymphocytes
cell mediated immunity
these are from stem cells in bone marrow and they mature in lymphatic tissue (lymph nodes).. and have two types
B lymphocytes
2 types: plasma cells, B memory cell
this occurs immediately after exposure to a previously encountered antigen (Penicillin), IgE causes mast cells to release histamine, can be life threatening because pt. may not be able to breath. examples: hayfever, asthma
type I (anaphylaxis)
using antibodies produced by another person to protect an individual from infectious disease.. antibody from another passes thru the placenta to a developing fetus..bone marrow transplant
passive immunity
what are the divisions of immune response?
humoral response
cell-mediated immune response
cell characteristic of lupus erythematosus and other autoimmune diseases
LE cell
this si when a mothers antibodies cross the placenta and destroy the newborns RBC’s
Rhesus incompatibility
allergic reactions with exaggerated responses and tissue destruction
hypersensitivity
destruction of fibrolasts
lymphotoxin
the study of immune reactions involved in disease
immunopathology
this has the capacity to remember and responds more quickly when a substance enters the body to a second time
immune response
these suppress the functioning of the B lymphocytes and T- Killer cells that are active in surveillance against virally infected cells of tumor cells
T- Suppressor cells
these can occur naturally or can e acquired via vaccination, immunization, sometimes requires a booster (ex-tetanis)
active immunity
delayed hypersensitivity-cell mediated response-cell mediated response-
tuberculin test (PPD)(Mantoux), skin reaction occurs if tested has previously been exposed to the organism causing TB
respons. for the rejection of tissue, grafts,transplanted organs
type IV (cell-mediated)
T lymphocytes and macrophages
cel (l mediated immune response (cmi)
involves the production of antibodies (B lymphocytes primary)
humoral response
mucosal infammation
mucositis
2nd type of B lymphocyte and retains the memory of previously encountered antigen and the duplicates
B memory cell
T cell.. maturs in thymus and helps with cell mediated immunity
T lymphocyte
deficiency of the immune response resulting from hypoactivity or decreased numbers of lymphoid cells
immunodeficiency
allergic reaction causing the release of vasoactive substances such as histaime; causes respiratory distress
anaphylaxis
what are some characteristics of hypersensitivity to drugs?
drugs can act as antigens
patients with multiple allergies are more likely to have allergic reactions to drug
causes a type I allergy
anaphylaxis, urticaria and angioedema systemic anaphylaxis can be fatal
penicillin 300 deaths per year
what do lymphokines consist of?
interleukins
lymphotoxin
interferon
disease caused by a microorganism that does not ordinarily cause a disease but becomes pathogenic under certain circumstances
opportunistic infection
tumor like mass of inflammatory tissue of macrophages surrounded by lymphocytes
granuloma
this is active in phagocytosis, link between the inflammatory and immune responses and can act as antigen-presenting cells
macrophages
a microorganism that causes disease
pathogenic microorganism
the increased responsiveness that results from the retained memory of an already encountered antigen
immunity
