Scope Recent evidences demonstrate that abnormal gut microbiota (GM) might be involved in the pathogenesis of Alzheimer's disease (AD). However, role probiotics preventing AD by regulating GM–gut–brain axis remains unclear. Here, anti‐neuroinflammatory effect and its mechanism probiotic Clostridium butyricum (CB) against is investigated axis. Methods results APPswe/PS1dE9 (APP/PS1) transgenic are treated intragastrically with CB for 4 weeks then cognitively tested. Amyloid‐β (Aβ) burden,...

ABSTRACT The interferon (IFN) system, including various IFNs and IFN-inducible gene products, is well known for its potent innate immunity against wide-range viruses. Recently, a family of cytidine deaminases, functioning as another retroviral infection, has been identified. However, regulation remains largely unknown. In this report, we demonstrate that through regular IFN-α/β signal transduction pathway, IFN-α can significantly enhance the expression apolipoprotein B mRNA-editing...

Cellular cytidine deaminases APOBEC3 family is a group of potent inhibitors for many exogenous and endogenous retroviruses. It has been demonstrated that they induce G to A hypermutations in the nascent retroviral DNA, resulting from cytosine (C) uracil (U) conversions minus-stranded viral DNA. In this report, we have result C U conversion DNA human immunodeficiency virus type 1 (HIV-1) could trigger degradation mediated by glycosylases-2 (UNG2) apurinic/apyrimidinic endonuclease (APE)....

Abstract Ischemic stroke is a frequent cause of mortality and disability, astrocyte reactivity closely associated with injury outcomes. Fibroblast growth factor 21 (FGF21), an endogenous regulator, has been shown to perform pleiotropic functions in central nervous system (CNS) disorders. However, studies on neurological diseases have paid little attention the effects detailed mechanisms FGF21 astrocytes. Here, we found elevated serum levels patients transient middle cerebral artery occlusion...

Abstract Background The diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) method has been used to evaluate glymphatic system function in patients with migraine. However, since model cannot accurately describe coefficient of nerve fibre crossing region, we proposed a kurtosis ALPS (DKI-ALPS) Methods study included 29 healthy controls and 37 We data from 3T MRI scanner calculate DTI-ALPS DKI-ALPS indices two groups. compared between groups using two-sample t-test...
