Abstract Tauopathies are neurodegenerative diseases that pathologically characterized by accumulation of misfolded microtubule-associated protein tau aggregates in the brain. Deubiquitination, particularly OTULIN, a unique deubiquitinase targeting methionine-1 (M1) linkages from linear ubiquitin chain assembly complex (LUBAC)), is reportedly associated with neurotoxic proteins several diseases, likely including tauopathies. To investigate potential roles OTULIN tauopathies, we analyzed interactome hippocampal tissues PS19 transgenic (Tg) mice and their non-transgenic (nTg) littermate controls using affinity purification-mass spectrometry (AP-MS). We identified 705 800 enriched Tg nTg samples, respectively, false discovery rate (FDR) <1%. Of these, 189 205 were classified as probable interactors groups, based on Significance Analysis INTeractome (SAINT) score ≥0.80 FDR ≤ 5%. A total 84 group, while 100 controls. Functional enrichment analyses revealed OTULIN-interacting group pathways related to spliceosome, complement coagulation cascades, ribosome, whereas those immune response autophagy. These findings suggest may play critical role pathogenesis tauopathy this mouse model. Highlights analyzed. ribosome. implicated ATP2A2 an specifically enhanced mice.

Neuronal loss is one of the striking causes various central nervous system (CNS) disorders, including major neurodegenerative diseases, such as Alzheimer’s disease (AD), Parkinson’s (PD), Huntington’s (HD), and Amyotrophic lateral sclerosis (ALS). Although these diseases have different features clinical manifestations, they share some common mechanisms pathology. Progressive regional neurons in patients responsible for motor, memory, cognitive dysfunctions, leading to disabilities death. cell death linked pathways conditions. Protein misfolding aggregation, mitochondrial dysfunction, generation reactive oxygen species (ROS), activation innate immune response are most critical hallmarks diseases. Thus, endoplasmic reticulum (ER) stress, oxidative neuroinflammation pathological factors neuronal Even though exact not fully discovered, notable role mentioned well known. On this basis, researchers been prompted investigate neuroprotective effects targeting underlying determine a promising therapeutic approach treatment. This review provides an overview ER death, mainly discussing or molecules involved factors.

The redox process and cellular senescence are involved in a range of essential physiological functions. However, they also implicated pathological processes underlying age-related neurodegenerative disorders, including Alzheimer's disease (AD). Elevated levels reactive oxygen species (ROS) generated as result abnormal accumulation beta-amyloid peptide (Aβ), tau protein, heme dyshomeostasis is further aggravated by mitochondria dysfunction endoplasmic reticulum (ER) stress. Excessive ROS damages vital components such proteins, DNA lipids. Such damage eventually leads to impaired neuronal function cell death. Heightened oxidative stress can induce via activation the senescence-associated secretory phenotype exacerbate inflammation tissue dysfunction. In this review, we focus on how changes system contribute AD affected perturbations metabolism mitochondrial function. While potential therapeutic strategies targeting have received some attention, more research necessary bring them into clinical application.

Protein misfolding is prominent in early cellular pathology of Alzheimer's disease (AD), implicating pathophysiological significance endoplasmic reticulum stress/unfolded protein response (ER stress/UPR) and highlighting it as a target for drug development. Experimental data from animal AD models observations on human specimens are, however, inconsistent. ER stress associated UPR are readily observed vitro some model animals. In the brain, components markers well transducers at Braak stages III-VI with severe neuropathology neuronal death. The picture, further complicated by brain region- cell type-specificity AD-related pathology. Terms 'disturbed' or 'non-canonical' stress/UPR were used to describe discrepancies between experimental classic cascade. Here we discuss possible 'disturbing' 'interfering' factors which may modify pathogenesis. We focus dysregulation Ca2+ homeostasis, store-operated entry, interaction mitochondria. suggest that detailed study CNS type-specific alterations homeostasis deepen our understanding dysproteostasis.

The microbiota-gut-brain axis is an important pathway of communication and may dynamically contribute to Alzheimer's disease (AD) pathogenesis. Pathological commensal gut microbiota alterations, termed as dysbiosis, can influence intestinal permeability break the blood-brain barrier which trigger AD pathogenesis via redox signaling, neuronal, immune, metabolic pathways. Dysbiosis increases oxidative stress. Oxidants affect innate immune system through recognizing microbial-derived pathogens by Toll-like receptors initiating inflammatory process. Most microbiome research work highlights relationship between AD, but contributory connection precise bacteria brain dysfunction in pathology cannot be fully demonstrated. Here, we summarize current information fundamental connections stress, inflammation, dysbiosis AD. This review emphasizes on involvement regulation responses including central peripheral cross-talk. It provides insights for novel preventative therapeutic approaches

Type 2 diabetes (T2D) and Alzheimer’s diseases (AD) represent major health issues that have reached alarming levels in the last decades. Although growing evidence demonstrates AD is a significant comorbidity of T2D, there ~1.4–2-fold increase risk developing among T2D patients, involvement possible common triggers pathogenesis these two remains largely unknown. Of note, recent mechanistic insights suggest lipotoxicity could missing ring pathogenetic mechanisms linking to AD. Indeed, obesity, which represents main cause lipotoxicity, has been recognized as factor for both pathological conditions. Lipotoxicity can lead inflammation, insulin resistance, oxidative stress, ceramide amyloid accumulation, endoplasmic reticulum ferroptosis, autophagy, are shared biological events In current review, we try provide critical comprehensive view molecular pathways activated by AD, attempting summarize how drive future research open way new therapeutic perspectives.
