Endotoxin receptor found on macrophages CD14
Cytokines that promotes B cell growth and differentiation IL-4, IL-5
Cytokines that are produced by Th1 cells IL-2, IFNgamma
Cytokines that are produced by Th2 cells IL-4, IL-5, IL-10
Cytokine involved in growth and activation of eosinophils IL-5
cytokine secreted by helper T cells and activates macrophages IFN-gamma
cytokine that inhibits macrophage activation IL-10
pyogens secreted by monocytes and macrophages IL-1, IL-6, TNFalpha (acute phase cytokines)

What composes the coding region for each specific antigen receptor on B and T cells Rearrangements of DNA segments named variable (V), diversity (D), and joining (J)
How does the rearrangement process begin? with breaks in the dsDNA a recombination signal sequences (RSSs) that flank the V,D, and J coding regions
How is V(D)J recombination initiated? by the recombination activating gene complex (RAG 1 and 2)
What happens if there are mutations in either of the RAG genes? the inability to initiate V(D)J rearrangements causes an arrest of B and T cell development
Immunoglobin associated with allergies because it is bound by mast cells and basophils and causes them to degranulate and release their histamine IgE

Present in large quantities on the membrane of many B cells IgM, IgD
Crosses the placenta and confers imunity to neonates in the first few months of life IgG
Can occur as a dimer IgA
Largely confined to the intravascular pool and is the predominant early antibody frequently seen in the immune response to infectious organisms and with complex antigens IgM
Distributed evenly between the intravascular and extravascular pools IgG
The predominant ig in mucoserous secretions like saliva, colostrum, milk, tracheobronchial secretions, and genitourinary secretions IgA
Can be a pentamer IgM
