What are the two types of immunity?
Innate immunity, Acquired immunity
What type of immunity is present at birth?
What type of immunity is present after birth?
What type of immunity is non-specific?
What type of immunity is specific?
This type of immunity has antibodies that develop after exposure to an antigen.
acquired active immunity
This type of immunity has antibodies that are transferred from another source
acquired passive immunity
This type of active immunity is through vaccines containing the pathogen's antigens
This type of active immunity is through environmental exposure to pathogens and thus their antigens
This type of passive immunity (acquired passive) has antibodies acquired from the mother
This type of passive immunity (acquired passive) is by an injection of antibodies
An example of this type of immunity is touching someone else's cell phone or getting coughed on and having bacteria/infection pass your way
This type of immunity is where you are given a shot (dead organism that contains the antigens body needs to recognize invader)
An example of this type of immunity is through breast milk
Passive naturally acquired
This type of immunity is where you are given some sort of immunization but instead of the antigen you are given B cell antibodies
What are the four properties of immunity?
Specificity, Versatility, Memory, Tolerance
This property of immunity has each T or B cell that responds only to a specific antigens and ignores all others.
This property of immunity the body produces many types of lymphocytes (each fights a different type of antigen)
This property of immunity has some active lymphocytes(memory cells)
This property of immunity stays in circulation and provide immunity against new exposure to same antigen
This property of immunity the immune system ignores our own antigens
What are the two main divisions of the immune response?
Cell mediated immunity, antibody-mediated immunity
cell mediated immunity goes with what cell type?
antibody mediated immunity goes with what cell type?
____ means that the T cells directly attack the pathogen
cell mediated immunity
____ means that the B cells indirectly attack by producing antibodies that attack the pathogen
antibody mediated immunity
another name for antibody mediated immunity is
What are three types of T cells?
Cytotoxic, Helper, Suppressor
This type of T cell attack viruses and bacteria and arrive on the scene first before B cells
This type of T cell stimulate function of T cells and B cells
This type of T cell inhibit function of T cells and B cells
This type of T cell is known as killer T cells
Another name for T cell is
_____ means a physical bonding to antigen
The antigens for antigen recognition are only recognized if they have ____
What does MHC stand for
Major histocompatibility complex
These are the membrane glycoproteins that bind to antigens and are found in all our body cells
How many classes of MHC proteins are there?
This class protein is found in all nucleated cells (living)
This class protein is found ONLY in Antigen Presenting Cells (apc, macrophage) and lymphocytes
What are the 5 types of APC cells?
Denditric, Kupffer, Langerhans, macrophages, microglia
Where can denditric cells be found?
lymph nodes and spleen
Where can macrophage cells be found?
Where can kupffer cells be found?
where can Langerhans be found?
where can microglia be found?
Central nervous system
What does APC stand for?
antigen presenting cells
What is another name for Helper cells?
These recognize and bond with a specific antigen
inactive t cell receptors
_____ recognized a class I or class II MHC protein that is presenting the foreign antigen
inactive t cell receptors
What does CD stand for?
clusters of differentiation designation
Where are CD markers found?
T cell membranes
What does Costimulation mean
____ is necessary for a cytotoxic t cell (killer t cell) to be activated
Receptor on _______ cell binds to foreign antigen presented by a MHC-II protein embedded in an APC
CD4 (inactive helper T cell)
Receptor on _______ cell binds to foreign antigen presented by a MHC-I protein embedded in a viral filled body cell
CD8 (inactive cytotoxic T cell)
What are three actions of cytotoxic T cells?
release perforin, secrete poison, activate genes
This cell is produces with cytotoxic t cells
Memory t cells
This type of t cell secrete suppression factors, inhibit responses of t and b cells, act after initial immune response, limit immune reaction to single stimulus
suppressor t cells
This type of T cell secretes cytokines
helper t cells
What are four functions of cytokines
Stimulate t cell division, attract and stimulate macrophages, attract and stimulate nk cells, promote activation of B cells
This type of cell attack both viruses and bacteria, arrive on the scene later than T cells
How many stages do B cells develop
This stage of b cell development is pre-b cells develop by a few months of age in the bone marrow
This stage of development of b cells occurs in lymph nodes, lymphatic nodules, and spleen where they stay put
What are the three steps of b cells
sensitization, activation, division and differentiation
In this step the b cell is exposed to foreign antigens
once b cells are differentiated what are they called
what are the five classes of antibodies (also known as immunoglobulins)
IGA, IGD, IGE, IGG, IGM
This is the predominant class produced after initial contact with an antigen ; the anti-a and anti-b antibodies are in this class
What percentage of IGM is found in blood?
What is the most abundance class of antibody?
What percentage of IGG is found in blood?
What class of antibody is found in mucus and saliva?
What class of antibody is involved in allergic and hypersensitivity reactions, provides protection against parasitic worms
What class of antibodies precise function is unknown but is involved in activation of b cells
