Yi-Zhi-Fang-Dai Formula Exerts a Protective Effect on the Injury of Tight Junction Scaffold Proteins in Vitro and in Vivo by Mediating Autophagy through Regulation of the RAGE/CaMKK β/AMPK/mTOR Pathway.
This study aimed to explore the underlying mechanism of YZFDF in alleviating the injury of TJ proteins. We examined the impacts of YZFDF on autophagy-related proteins and the histopathology of Aβ in the APP/PS1 double-transgenic male mice. We then performed the free intracellular calcium levels [Ca2+]i analysis and the cognitive behavior test of the AD model. Our results showed that YZFDF ameliorated the injury of TJ proteins by reducing the mRNA transcription and expression of the receptor for advanced glycation end-products (RAGE), the levels of [Ca2+]i, calmodulin-dependent protein kinase β (CaMKKβ), phosphorylated A...

Naringenin Produces Neuroprotection Against LPS-Induced Dopamine Neurotoxicity via the Inhibition of Microglial NLRP3 Inflammasome Activation
Conclusions: This study demonstrated that NAR targeted microglial NLRP3 inflammasome to protect DA neurons against LPS-induced neurotoxicity. These findings suggest NAR might hold a promising therapeutic potential for PD. Background Parkinson's disease (PD) is the second most prevalent central nervous system (CNS) degenerative disease. It is characterized by slow and progressive loss of dopamine (DA) neurons in the midbrain substantia nigra (SN) with the accumulation of α-synuclein in Lewy bodies and neuritis (1). Although the etiology of PD remains unclear, amounts of studies have suggested that ne...

IFIT5 Participates in the Antiviral Mechanisms of Rainbow Trout Red Blood Cells
We described a new defense mechanism based on IFIT5 antiviral activity in nucleated RBCs that appeared to contribute to halting the VHSV infection. This finding sheds light into novel antiviral therapeutics to mitigate the economic losses and social impact caused by viral infections in the aquaculture industry. This work broadens the knowledge of fish nucleated RBCs functions and their role in the immune response to viral infections. Ethics Statement Experimental protocols and methods relating to experimental animals were reviewed and approved by the Animal Welfare Body and the Research Ethics Committee at the University...
