(Submitter supplied) The prion protein, PrPC, is well known as an essential susceptibility factor for neurodegenerative prion diseases, yet its function in normal, healthy cells remains uncertain. A role in synaptic function has been proposed for PrPC, supported by its cell surface expression in neurons and glia. Here, in mouse retina, we localized PrPC with synaptic proteins EAAT5, CtBP2 and PSD-95, which are present at junctions between photoreceptors and bipolar cells. more...

(Submitter supplied) Background: Astrocytes have recently gained attention as key players in the pathogenesis of neurodegenerative diseases, including Alzheimer's disease. Numerous differentiation protocols have been developed to study human astrocytes in vitro. However, the properties of the resulting glia are inconsistent, making it difficult to select an appropriate method for a given research question. Therefore, we compared three approaches for the generation of iPSC-derived astrocytes. more...

(Submitter supplied) Parkinson’s disease (PD), a prevalent neurodegenerative disorder, is primarily characterized by progressive loss of ventral midbrain dopamine (DA) neurons. This focal degeneration makes PD suitable for cell replacement therapies and clinical trials using stem cell derived-DA neurons are ongoing. An emerging alternative to cell transplantation for brain repair is in vivo reprogramming, where resident glia is converted into neurons directly inside the brain. more...

(Submitter supplied) Brain calcification, the ectopic mineral deposits of calcium phosphate, is a common radiological finding in elderly and in various neurodegenerative disorders and a diagnostic criterion for primary familial brain calcification (PFBC). We made use of single nuclei RNA sequencing to understand the effect of calcification pathology in the Pdgfb (ret/ret) model of PFBC. Calcifications are located in deep brain regions - hypothalamus, thalamus, mid brain, pons of Pdgfb (ret/ret) mice and absent in control Pdgfb (ret/wt) mice. more...

(Submitter supplied) Deficits in chemosensory processing are associated with healthy aging, as well as numerous neurodegenerative disorders, including Alzheimer’s Disease (AD). In many cases, chemosensory deficits are harbingers of neurodegenerative disease, and understanding the mechanistic basis for these changes may provide insight into the fundamental dysfunction associated with aging and neurodegeneration. The fruit fly, Drosophila melanogaster, is a powerful model for studying chemosensation, aging, and aging-related pathologies, yet the effects of aging and neurodegeneration on chemosensation remain largely unexplored in this model, particularly with respect to taste. more...

Using immunocompetent genetically engineered mouse models, we demonstrate the predominant non-neoplastic cell population are infiltrating myeloid cells, including peripheral monocytes and brain resident microglia. Single cell RNA sequencing, flow cytometry, and immunohistochemistry demonstrate the presence of unique myeloid cell populations distinctly shaped by the specific histone mutation. more...

(Submitter supplied) The central nervous system (CNS), despite the presence of strategically positioned anatomical barriers designed to protect it, is not entirely isolated from the immune system. In fact, it remains physically connected to and can be influenced by the peripheral immune system. How the CNS retains such responsiveness while maintaining “immune privilege” remains an outstanding conundrum. In searching for molecular cues that derive from the CNS and allow its direct communication with the immune system, we discovered a repertoire of CNS-derived endogenous guardian peptides presented on major histocompatibility complex (MHC) II molecules at the CNS borders. more...

(Submitter supplied) Parkinson's disease (PD) is a neurodegenerative disease characterized by bradycardia, static tremor, rigidity and postural instability. At present, the current knowledge remains inadequate for the connection between the disease severity and peripheral immune response. In the present study, using single-cell RNA sequencing (scRNA-seq), we profiled peripheral blood mononuclear cells (PBMCs) from clinical cases, including 2 early PD, 2 advance PD and 2 matched controls, representing five major immune cell subsets: T cells (CD4+, CD8+), monocytes, B cells, natural killer (NK) cells and hematopoietic stem cells (HSCs). more...

(Submitter supplied) The protein homeostasis (proteostasis) network encompasses a myriad of mechanisms that maintain the integrity of the proteome by controlling various biological functions, including protein folding and degradation. Alas, aging-associated decline in the efficiency of this network enables protein aggregation and consequently the development of late onset neurodegenerative disorders, such as Alzheimer’s disease (AD). more...

(Submitter supplied) Loss of proteostasis is an aging hallmark and the culprit of many age-related diseases. Different cell compartments experience distinctive challenges to maintain protein quality control but it remains underexplored how subcellular proteostasis is regulated by aging. Here, by targeting the misfolding_x0002_prone FlucDM luciferase to the cytoplasm, mitochondria, and nucleus, we have established transgenic sensors to examine subcellular proteostasis in Drosophila. more...

(Submitter supplied) Conserved neuropathologies across multiple neurodegenerative diseases have identified shared causal pathways for neurodegeneration. One pathway involves the RNA-binding protein TDP-43, whose nuclear exclusion and cytoplasmic accumulation are established drivers of neurodegeneration. TDP-43 mislocalization is attributed to defective nucleocytoplasmic transport (NCT), but the underlying mechanisms are unclear. more...

An illustrative case is olfaction, where the olfactory bulb (OB) undergoes deterioration with age, resulting in reduced olfactory ability. A decline in olfaction is also associated with early symptoms of neurodegenerative diseases, including Alzheimer’s disease (AD) and Parkinson’s disease (PD). However, the underlying reasons are unclear. more...
