The role of chromatin biology and epigenetics in disease progression is gaining increasing recognition. Genes that escape X chromosome inactivation (XCI) can impact neuroinflammation through epigenetic mechanisms. Our previous study has suggested that the X escapee genes Kdm6a and Kdm5c are involved in microglial activation after stroke in aged mice.

Background: The brain is shielded from the peripheral circulation by central nervous system (CNS) barriers, comprising the well-known blood-brain barrier (BBB) and the less recognized blood-cerebrospinal fluid (CSF) barrier located within the brain ventricles. The gut microbiota represents a diverse and dynamic population of microorganisms that can influence the health of the host, including the development of neurological disorders like Alzheimer's disease (AD). However, the intricate mechanisms governing the interplay between the gut and brain remain elusive, and the means by which gut-derived signals traverse the CNS barriers remain unclear.

Background: Compelling evidence has shown that long non-coding RNAs (lncRNAs) contribute to Alzheimer's disease (AD) pathogenesis including β-amyloid plaque deposition (Aβ) and intracellular neurofibrillary tangles. In this study, we aimed to investigate the critical role of lncRNA Gm20063 in AD.
Method: Six-month-old male APP/PS1 transgenic mice and wild type (WT) C57BL/6 (B6) littermates were obtained from the Nanjing University Animal Model Research Center.

Background: The classic mode of STING activation is through binding the cyclic dinucleotide 2'3'-cyclic GMP-AMP (cGAMP), produced by the DNA sensor cyclic GMP-AMP synthase (cGAS), which is important for the innate immune response to microbial infection and autoimmune disease. Modes of STING activation that are independent of cGAS are much less well understood. We wanted to explore the interactome of STING on the organelles during its trafficking route and to understand the regulatory network of STING signaling.

Background: Patients with Alzheimer's Disease (AD) frequently manifest comorbid neuropsychiatric symptoms (NPS) with depression and anxiety being most prevalent. Previously we identified shared genetic risk loci between AD and major depressive disorder (MDD). In another study, we constructed a polygenic risk score (PRS) based on MDD-GWAS data and demonstrated its performance in predicting depression onset in LOAD patients.
