can be attracted to the site of an infection following activation of complement

All of these

are derived from bone marrow stem cells

are a type of phagocyte that can engulf and kill bacteria

B cells that recognize high concentrations of antigens (self) in the absence of other signals undergo apoptosis in the bone marrow

B cells can undergo class switching and produce a different antibody type

B cells synthesize antibodies and put them on their cell surface

B one marrow stem cells migrate to the thymus and develop into B cells

are secreted out into the environment to bind antigens

recognize peptides not associated with MHC molecules

recognize peptides associated with MHC class I molecules

interleukin

CD8

HLA

actin

In the thymus, CD8 T cells undergo positive selection only, whereas CD4 T cells undergo negative selection only

CD8 T cell receptor recognizes epitopes that are also commonly recognized by B cells

CD8 T cells only recognize virus-infected cells

CD8 T cells can kill individual virus-infected cells in a contact dependent fashion

induce apoptosis in virus-infected small intestinal epithelia cells
