IL 5
B cell maturation
Plasma B cells
Undergoes Class Switch
Early stages of infection
mainly IgM
Innate antibody
Very nonspecific
Pentamer
BCR
IgD
IgM
Can accept antigen and trigger release of chemokine same way APC will
EARLY STAGES: IgM
IgM will act as a BCR and trigger
OR
cause class switch
b/c chemokine cause clonal selection and clonal expansion
APC will trigger
Later stages of infection
mainly IgG
specific antibody
Transplacental
Clumps and neutralizes pathogens
produces the antibodies
Memory B cells
stores antibodies in case of second exposure
Memory T cells
IL 10
inhibits maturation and proliferation after a while
IL 4
Clonal Selection
Clonal Expansion
cannot happen without cell mediated
