Abstract:
Objective To investigate the mRNA expression level of neurogranin on peripheral blood mononuclear cells(PBMCs)from patients with systemic lupus erythematosus(SLE).Methods Top 20 tags of SLE PBMCs SAGE library were searched from normal lymphocytes SAGE library including navie-T,Th1,Th2, CD8+T, NK and B cells,and their abundance was compared.The mRNA expression level of neuro-granin,a differential over-expressed tag,was detected in 35 cases of SLE and 15 normal controls by reversetranscription-polymerase chain reaction (RT-PCR).Results Neurogranin tag could only be detected in SLE PBMCs SAGE library,but was hardly found in normal lymphocyte SAGE library.However,either SLE pa-tients or normal controls showed a detectable mRNA level of neurogranin on PBMCs by RT-PCR.The mRNA level of neurogranin in active SLE patients was significantly increased than those in controls(P＜0.001).but only slightly increased in inactive SLE patients (P＞0.05).Conclusion Neurogranin,as a novel proapototic factor,is overexpressed on PBMCs of SLE patients.It may be involved in the regulation of abnormal immune responses in lupus.
