C-Reactive Protein is an Acute-Phase Reactant That Will Bind to Components

Question

C-reactive protein is an acute-phase reactant that will bind to components of
A) IL-1.
B) TNF-alpha.
C) bacterial cell surfaces.
D) host cell membranes.
E) cytokines.

Accepted Answer

C-reactive protein can bind to bacterial cell surfaces and activate complement, leading to inflammation and destruction of the bacterial cell. It can also bind to other components of the immune system, such as Fc receptors on phagocytic cells, and enhance opsonization and phagocytosis of the bacteria. IL-1, TNF-alpha, and cytokines are not components of bacteria, and host cell membranes are not typically targeted by acute-phase reactants like C-reactive protein.
