Conclusion
The elevated LIGHT levels may reflect a persistent chronic inflammatory response that may have been induced during early stages of the disease. We speculate that this derangement of LIGHT may be important for atherogenetic process of ischemic stroke.
Methods
The soluble LIGHT protein was analyzed by an enzyme-linked immunosorbent assay in peripheral blood of patients with acute ischemic atherosclerotic stroke (n = 20), asymptomatic carotid stenosis (n = 19) and normal controls (n = 23).
Results
During the initial 24 h after onset, the stroke patients had an increased plasma LIGHT levels as compared with normal controls. Moreover, the plasma LIGHT levels of the stroke patients were correlated with blood platelet count (r = 0.6341, P = 0.0027).
