what is the role of dendritic cells in adaptive immunity?

perforin inducted apoptosis by CTLs

fas-mediated apoptosis by CTLs

define primary response

define secondary response

key difference between IgM and IgG with regards to antigen affinity

where does antigen independent clonal selection occur?

where does antigen dependent clonal selection occur?

naive B lymphocytes respond to first antigen challenge by

shortly after antigen exposure and production of IgM, B cells then produce

B cells expressing IgM and IgD are then able to be stimulated by helper T cells and undergo

what determines which class the B cell will switch to?

affinity maturation

how do B cells respond to a repeated challenge?

cytotoxic T cells (CTLs)

CTLs are able to induce programmed cell death (apoptosis) of virus infected cells - 2 pathways

primary antibody responses

secondary antibody responses

Secreted specific antibodies can:

Secretory IgA

Naïve B lymphocytes respond to the first challenge with the antigen by:

Affinity maturation is provided by:

B lymphocytes respond to the repeated challenge with the same antigen by:

T cell cytotoxicity is mediated by:

APC and CD4+ T helper cells provide assistance for:

T cell maturation is regulated by
