actin

HLA

interleukin

CD8

recognize peptides not associated with MHC molecules

recognize peptides associated with MHC class I molecules

recognize peptides associated with MHC class II molecules

are secreted out into the environment to bind antigens

T cells

none of these

monocytes

B cells

CD4

CD7

CD9

CD8

are derived from bone marrow stem cells

are a type of phagocyte that can engulf and kill bacteria

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

All of these

A cytosolic protein

A nuclear protein

A protein bound to the endoplasmic reticulum (ER) membrane

A cell surface protein

CD8 T cells only recognize virus-infected cells

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

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

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

eosinophils

neutrophils

monocytes

basophils

They are antigens found in some members of different species

They are antigens found in all members of different species

They are antigens found in some members of a species

They are antigens found in all members of a species

By the combination of different heavy and light chains that form the antigen binding site

Antibody proteins can physically change their shape to bind different epitopes

By rearrangements of the DNA encoding the variable regions of the heavy and light chains

Both (a) and (b)
