PREPARATION
define immunity
an enhanced state of responsiveness that activates a collection of cells, chemicals and
processes that function to protect the immune barriers (skin, GI, respiratory tract, etc)
from foreign antigens
define alloantibodies
immune antibodies produced against foreign antigens from another person of the same
species
define autoantibodies
malfunctioning proteins produced by the immune system that mistakenly attack the
body's own healthy cells, tissues, and organs rather than foreign invaders.
what is the pathologic version of the ability to "recognize and eliminate foreign
antigens"
IMMUNODEFICIENCY
ex; SCID, chronic granulomatous disease
what is the pathologic version of the ability to "restrain to self antigens"
AUTOIMMUNITY
ex; SLE, sjogren
what is the pathologic version of the "growth and expansion of immune cells"
MALIGNANCY
ex; multiple myeloma
give basic characteristics of natural/innate immunity
- present at birth
- nonspecific
- various barriers to external insults (skin, membranes, macrophages, neutrophils,
monocytes, etc)
give basic characteristics of adaptive immunity
- expressed AFTER exposure to a given substance and is specific
- involves specific receptors on lymphocytes and the participation of macrophages for its
expression
- consists of humor immunity AND cell mediated immunity
define humoral immunity
mediated by antibodies
define cell mediated immunity
mediated by lymphocytes
what are the categories of LYMPHOID cells
- T lymphocytes
- B lymphocytes
,- antigen presenting cells
- NK cells
what is the function of T lymphocytes
- cell mediated immunity = cytotoxicity
- helper of humoral immunity
what is the function of B lymphocytes
HUMORAL immunity
- memory B cells
- production of antibodies
what are the categories of NON-LYMPHOID cells
- neutrophils and eosinophils
- basophils and mast cells
what are the factors of humoral immunity
- immunoglobulins
- completement activation
- cytokines
what is the function of immunoglobulins
- circulate in blood and appear at mucosal surfaces to come in contact with potentially
pathogenic organisms
- can be bound to B cells for stimulation of further immunoglobulin secretion
what is the role of complement activation in humoral immunity
- role of enzymatically destroying targets (cells, bacteria) either at direction of antibody
or b y other means (alternative or mannose binding pathway)
what is the function of cytokines
- chemoattractant
- immune effectors
what are the Histocompatibility antigens
MHC/HLA
what are the mechanisms of immunologic injury
Type 1-4 Hypersensitivity
what are the 2 immediate progenitors of the multipotential hematopoietic stem
cell
- common myeloid progenitor
- common lymphoid progenitor
normal cell count ranges are set for _____ and _____
age;gender
what categories are normal cell count ranges set for
- overall WBC
- differential count
- absolute count
what are the types of WBC counts
- TOTAL COUNT
- differential ( different types of WBC)
what cell count is specifically very important in hematolymphoid disease
WBC count
how is the differential WBC count reported
, absolute cell count = total WBC x cell types
what helps determine if there is adequate, decreased, or increase WBCs present
absolute cell count
what suffixes denote an increase in cells
- philia
- cytosis
what suffixes denote an decrease / deficiency in cells
- penia
what is the function of platelets
first responders
- form hemostatic plus to stop blood loss from injured vessels = clotting
- maintain the integrity of blood vessels
- promote coagulation of plasma factors
what happens if you dont have enough platelets
- bleeding
- microvascular trauma (petechia)
what happens if you have TOO many platelets
clotting
what is the function of erythrocytes
RBC
- transport of maintenance of hemoglobin
- hemoglobin (transport oxygen and carbon dioxide) is produced in precursor cells of the
erythrocytes
what if you dont have enough erythrocytes
signs and symptoms of end organ dysfunction
ex; dizziness in the brain, fatigue, blacking out, myocardial ischemia, cell necrosis
what if you have too many erythrocytes
- block the laminar flow of your blood
- thrombosis due to thick blood
what are the 2 types of antigen presenting cells that we focus on
- macrophages
- dendritic cells
what is the function of macrophages (APC) (4)
- phagocytosis
- process ingested antigens and present them in association with MHC molecules on
their membrane
-secrete cytokines (IL1) for lyse of tumor cells
- effector cells for cell mediated immunity
what if you dont have enough macrophages / they dont work well
- disease
- immunodeficiency
what if you have too macrophages / they are working too much
- robust immune responses
- eat normal things = cellular destruction= attacking self
