Interferon-induced Transmembrane Protein 3 Prevents Acute Influenza Pathogenesis in Mice / 生物医学与环境科学（英文）

Objective@#Interferon-induced transmembrane protein 3 (IFITM3) is an important member of the IFITM family. However, the molecular mechanisms underlying its antiviral action have not been completely elucidated. Recent studies on IFITM3, particularly those focused on innate antiviral defense mechanisms, have shown that IFITM3 affects the body's adaptive immune response. The aim of this study was to determine the contribution of IFITM3 proteins to immune control of influenza infection .@*Methods@#We performed proteomics, flow cytometry, and immunohistochemistry analysis and used bioinformatics tools to systematically compare and analyze the differences in natural killer (NK) cell numbers, their activation, and their immune function in the lungs of -/- and wild-type mice.@*Results@#-/- mice developed more severe inflammation and apoptotic responses compared to wild-type mice. Moreover, the NK cell activation was higher in the lungs of -/- mice during acute influenza infection.@*Conclusions@#Based on our results, we speculate that the NK cells are more readily activated in the absence of IFITM3, increasing mortality in -/- mice.

Correlation between the hemodynamic parameters of extracranial vertebral artery and the severity and location of intracranial vertebral artery stenosis / 中华超声影像学杂志

Objective@#To analyze the effects of the degree and location of intracranial vertebral artery(VA) lesions on the hemodynamic parameters of extracranial VA.@*Methods@#A total of 275 consecutive patients who were diagnosed as posterior circulation ischemic stroke or transient ischemic attack (TIA) with unilateral intracranial VA stenosis or occlusion in the Department of Neurology and Neurosurgery of Capital Medical University Xuanwu Hospital from January 2015 to December 2017 were enrolled. All patients were examined by head and neck vascular ultrasound, CT angiography (CTA) and/or digital subtraction angiography (DSA) within one week. According to the results of DSA or CTA, the patients were divided into mild stenosis group(53 patients), moderate stenosis group(62 patients), severe stenosis group(58 patients) and occlusion group(102 patients). The inner diameter (D), peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) of the extracranial segment (V2 segment) of the VA were recorded and analyzed.@*Results@#The PSV and EDV in the severe stenosis group and the occlusion group were significantly lower than those in the mild stenosis group and the moderate stenosis group (P=0.000), and the PSV and EDV in the occlusion group were significantly lower than those in the severe stenosis group[ (31±10) cm/s vs (46±12)cm/s, (5±4)cm/s vs (15±7)cm/s; all P=0.000], RI was significantly higher than the other three groups (0.85±0.12, 0.70±0.10, 0.66±0.07, 0.64±0.06, respectively; all P=0.000); RI in the severe stenosis group were not significantly different from those in the mild to moderate stenosis groups (P=0.044, 0.223). There were no significant differences in the inner diameter, PSV, EDV and RI between the subgroups in the severe stenosis group before or after the PICA (posterior inferior cerebellar artery)(P=0.130, 0.322, 0.865, 0.227). However, the EDV decreased and RI increased in the occlusive subgroup before the PICA when compared the subgroup after the PICA (all P=0.000).@*Conclusions@#The location and degree of intracranial VA lesions directly affect the changes of blood flow velocity and vascular resistance of extracranial VA, and the changes of low-speed and high-resistance hemodynamics of extracranial VA may indicate the existence of occlusive lesions in intracranial VA.

Objectives: To investigate the potential mechanism of cathepsins S inhibitor (CatS-I) affected ischemia-induced neovascularization in experimental mice. Methods: 8 week-old wild type (C57/BL6) mice were randomly divided into 2 groups: Control group, the mice received basic diet with intraperitoneal injection of 5% carboxymethylcellulose sodium and CatS-I group, the mice received basic diet with intraperitoneal injection of CatS-I (1mg/kg·d); all animals were treated for 17 days. n=20 in each group. Hind limb ischemia model was established at 3 days after injection in both groups. Blood flow was measured by laser Doppler blood flow analyzer, the ratio of ischemic area to non-ischemic area was calculated; protein expressions of peroxidase proliferation activated receptors-γ (PPAR-γ), p-Akt, p-eNOS and VEGF were examined by Western blot analysis at day 4 after the operation; frozen section of ischemic skeletal muscle was taken at 7 days after operation to measure capillary density by immunohistochemistry.Results: ① CatS-I inhibited blood flow recovery. Compared with Control group, CatS-I group had slower blood flow recovery in ischemic hind limb, P<0.05. ② CatS-I inhibited capillary formation. At 14 days after operation, capillary formation in non-ischemic skeletal muscles was similar between 2 groups, P>0.05; while in ischemic skeletal muscles, capillary density was lower in CatS-I group than Control group, P<0.01. ③ Compared with Control group, CatS-I group showed decreased protein expressions of PPAR-γ, p-Akt, p-Enos and VEGF, P<0.05. Conclusions: CatS-I regulated ischemia-induced neovascularization might be related to PPAR-γ activation and PI3K/Akt/eNOS signaling pathway in experimental mice.

miR-381-3p protects hippocampal neurons of depressive rats from injury via BDNF / 中国病理生理杂志

AIM:To investigate the effect of microRNA(miR)-381-3p on neuronal injury in the hippocampus of depressive rats and the possible regulatory mechanism.METHODS:The rat model of depression was established by sub-cutaneous injection of corticosterone and the model rats received fluoxetine treatment.The body weight,open field test and biochemical indexes were measured for judging the therapeutic effect of fluoxetine.The expression of miR-381-3p,brain-derived neurotrophic factor(BNDF),Bcl-2 and Bax in the hippocampus was determined.The cultured neonatal rat hipp-ocampal neurons were pre-transfected with miR-381-3p inhibitor and then incubated with corticosterone.The cell viability, and the expression of miR-381-3p, BNDF, Bcl-2 and Bax were detected.The targeted regulatory role of miR-381-3p in BDNF was verified by luciferase reporter assay.RESULTS:Compared with depression group,fluoxetine increased the body weight,the number of cross-field activities and the content of norepinephrine,inhibited the expression of miR-381-3p and promoted the expression of BNDF in the hippocampus.miR-381-3p silencing reversed the effect of corticosterone,resulting in the increase in the survival rate of hippocampal neurons, upregulation of BDNF and Bcl-2, and downregulation of Bax expression.miR-381-3p targeted the regulation of BNDF expression.CONCLUSION: Silencing miR-381-3p protects rat hippocampal neurons from corticosterone injury,and its mechanism may be related to the upregulation of BNDF expression.
