Previous studies have suggested the involvement of CD4 + T lymphocytes in cardiac remodelling. T-bet can direct Th1 lineage commitment. This study aimed to investigate the functional significance of T-bet in cardiac remodelling induced by pressure overload using T-bet global knockout rats. Increased T-bet levels were observed in rodent and human hypertrophied hearts. T-bet deficiency resulted in a less severe hypertrophic phenotype in rats. CD4 + T-lymphocyte reconstitution in T-bet-/- rats resulted in aggravated cardiac remodelling...

The generation of induced pluripotent stem cells (iPSCs) offers a great opportunity in research and regenerative medicine. The current poor efficiency and incomplete mechanistic understanding of the reprogramming process hampers the clinical application of iPSCs. MeCP2 connects histone modification and DNA methylation, which are key changes of somatic cell reprogramming. However, the role of MeCP2 in cell reprogramming has not been examined. In this study, we found that MeCP2 deficiency enhanced reprogramming efficiency and stimulated cell proliferation through regulating cell cycle protein expression in the early stage of reprogramming...

Polymorphic forms of etoricoxib have been reported in the literature and form I was considered to be the most stable one. However, in this work, it was found that form I and form V are enantiotropic by DSC analysis, solubility measurements and solution-mediated polymorphic transformation experiments with form V being more stable than form I at room temperature. Thermodynamic transition temperature is determined as (353.45 ± 0.10) K. Besides, form V would transform to form I with the seeding effect of form I at high temperature below the melting point of form V...

The development of an effective HIV-1 vaccine is still a global priority. In recent years, vaccinia virus (VV) has been widely used as an HIV-1 vaccine vector, but its immune efficacy against HIV-1 antigens needs to be optimized. The extracellular enveloped virus (EEV) of VV is capable of faster entry, earlier release, and long-range dissemination. We hypothesized that an improvement in EEV formation by the manipulation of VV genes involved in the EEV release would consequently cause an improved expression of the VV carrying HIV-1 Env antigen and a subsequent enhanced immune response...
