death domains

Biology; Immunology

Death domains were originally defined in proteins encoded by genes involved in programmed cell death or apoptosis, and are now known to be involved in protein–protein ...

acute-phase response

Biology; Immunology

The acute-phase response is a change in the blood that occurs during early phases of an infection. It includes the production of acute-phase proteins and also of cellular ...

Fcε receptor

Biology; Immunology

The high-affinity Fcε receptor (FcεRI) on the surface of mast cells and basophils binds free IgE. When antigen binds this IgE and cross-links FcεRI, it causes mast-cell ...

receptor-mediated endocytosis

Biology; Immunology

Receptor-mediated endocytosis is the internalization into endosomes of molecules bound to cell-surface receptors. Antigens bound to B-cell receptors are internalized by this ...

kinin system

Biology; Immunology

The kinin system is an enzymatic cascade of plasma proteins that is triggered by tissue damage to produce several inflammatory mediators, including the vasoactive peptide ...

B-cell co-receptor

Biology; Immunology

A complex of CD19, TAPA-1, and CR2 makes up the B-cell co-receptor; co-ligation of this complex with the B-cell antigen receptor increases responsiveness to antigen by about ...

Goodpasture’s syndrome

Biology; Immunology

Goodpasture’s syndrome is an autoimmune disease in which autoantibodies against basement membrane or type IV collagen are produced and cause extensive vasculitis. It is rapidly ...
