OBJECTIVE: To investigate the molecular alteration of immunity associated genes in patients with pulmonary embolism (PE) so as to preliminarily elucidate its pathogenetic mechanism. METHODS: Human cDNA microarray analysis was employed in this study, random variance model (RVM) corrected t-test was used for the statistical data analysis of differential gene expression. RESULTS: In comparison with control, mRNA expression of functional genes of neutrophils, monophagocytes, IFN regulating factors, TNF, adhesion molecules and T cells were significantly different in PE patients. However, gene expressions of B cell immune function and complement activation associated factors were not significantly different between two groups. CONCLUSION: Unbalance expression of immune function associated genes, especially down-regulated expression of T cell mediated function genes, in patients with PE indicates that the etiology of PE might be related to viral infection.
