(A) NLRC5 protein was quantified using ELISA. (B) Fluorescence photomicrographs of (B) mock-infected cells stained for NLRC5 and (C) LPAIV H5N2-infected macrophage cells. The blue color represents DAPI-nuclei specific staining and the green color represents FITC-NLRC5 specific staining. Data points are mean of three biological replicates with error bars showing standard deviation. *** p ≤ 0.001, **** p ≤ 0.0001.

    Article Snippet: In addition, to quantify the expression of NLRC5, a quantitative sandwich ELISA was performed using a commercial ELISA kit (MyBioSource, San Diego, CA, USA) as per the manufacturer's instructions.

    Simvastatin ameliorates t-PA-induced blood MMP-9/TIMP-1 ratio imbalance. Rats were pretreated with SIM (60 mg/kg/d) for the SIM+ group or water for the SIM- group for two weeks, then rats were received t-PA (10 mg/kg) for the t-PA+ group or normal saline for the t-PA- group 3 hrs after operation. Blood samples were collected via abdominal aorta puncture before sacrificed. ( A ) ELISA analysis of MMP-9 and TIMP-1 protein expression. ( B ) Real-time PCR analysis of MMP-9 and TIMP-1 mRNA levels. ( C ) The blood MMP-9/TIMP-1 protein ratio. ( D ) The blood MMP-9/TIMP-1 mRNA ratio. Bars express the mean ± SD of duplicates (n=6). ** p <0.01 t-PA alone versus t-PA plus SIM; && p <0.01 t-PA alone versus t-PA-/SIM-; ## p <0.01 versus sham group. Abbreviation: SIM, simvastatin.
