The vital cell stress protein, heat shock protein (Hsp)60, has recently been found in the circulation of healthy subjects over an extremely large concentration range. We performed an analysis of subjects with diabetes to determine whether Hsp60 is associated with biochemical markers of cardiovascular disease. Results showed that high circulating levels of Hsp60 are associated with clinically manifest cardiovascular disease. Hsp60 has cytokine-like actions, which may be responsible for this association.
