Adaptive Immune
Involve Lymphocytes including these two cells
B & T Cells
Both lymphocytes originate in red bone marrow which is what step in the what step in the lymphocyte development phase?
Origin
This type of immunity is when B cells make antibodies in response to an actual bacterial or viral infection
Naturally acquired
IGA
When T-cells are naive and have not encountered an antigen they are in two groups called
CD4 and CD8 cells
Adaptive immunity is specific, systemic, and has what?
Memory
Clonal Selection; Lymphocyte selected to differentiate into active cells by its first bonding to its specific antigen is what step in the stage of lymphocyte development?
Antigen encounter and activation
Immunity in response to a vaccine
Artificially acquired
Potent agglutinating agent, readily activates complement, first antibody released, larger that others, pentamer
Igm
CD4 cells become can these cells that activate B-cells and other t-cells and macrophages. They direct the immune response
Helper T-cells
Adaptive immune system has 2 main branches called what?
Humoral Immunity and Cellular Immunity
Most clones become these cells that fight infection
Effector Cells
Occurs when antibodies are introduced into the body; No memory cells
Passive Humoral Immunity
Causes mast cells and basophils to release histamine
IgE
CD4 cells can also become these cells that moderate the immune response
Regulatory T-cells
These mobilize adaptive defenses and provoke an immune response
Antigens
These cells are able to respond to the same antigen more quickly the next time it is encountered
Memory Cells
Immunity delivered from placenta to fetus or infant through milk
Naturally Acquired
Most abundant antibody in plasma; monomer; confers immunity from mom to baby
IgG
CD8 become these cells, capable of destroying cells harboring foreign antigens
Cytotoxic T-cells
The major presenting molecule
MHC Protein
Maturation is important for two main reasons which are
Immunocompetence and self tolerance
Immunity from an injection of serum or antivenom for snakes
Artificially acquired
Functions as a B cell receptor
IgD
MCH proteins are displayed by all cells except
RBCs
