Chaperone-related immune dysfunction: an emergent property of distorted chaperone networks

Molecular chaperones (heat shock proteins) are important components of cellular networks, such as protein-protein and gene regulatory networks. Chaperones participate in the folding of immunologically important proteins, presentation of antigens and activation of the immune system. Here, we propose that chaperone-related immune dysfunction might be more general than was previously thought. Mutations and polymorphism of chaperones and the regulators of their synthesis, heat shock factor-1, chaperone diseases, sick chaperones and chaperone overload might all affect (mostly impairing) immune responses.
