Equine spinal neurodegenerative conditions are frequently encountered in sport and racing horses and may be career-ending diagnoses. To further define the spatial transcriptomic landscape of equine dorsal root ganglia (DRG) in healthy adult horses, we investigated gene expression differences in distinct DRG regions using the GeoMx Digital Spatial Profiling from NanoString. Four human cell markers demonstrated high fidelity for equine cells; microtubule-associated protein 2 (MAP2), myelin basic protein (MBP), allograft inflammatory 104 factor 1/ionized calcium-binding adaptor molecule 1 (IBA1/AIF1), and Syto83 nuclear marker. Geometric regions of interest were then selected as MBP-rich, IBA1-high, and IBA1-low, and gene expression was compared. Experimental validation was achieved, with genes involved in myelination enriched in MBP-rich regions, and the identification of glia-specific genes enriched in IBA1-high regions. Thus, spatial transcriptomics with human cell markers was successful in equine DRG and can now be applied to determine cell-specific transcriptional changes during disease states.

Background: Functional and structural studies of the brain highlight the importance of white matter alterations in schizophrenia. However, molecular studies of the alterations associated with the disease remain insufficient.
Aim: To study the lipidome and transcriptome composition of the corpus callosum in schizophrenia, including analyzing a larger number of biochemical lipid compounds and their spatial distribution in brain sections, and corpus callosum transcriptome data.

Previous studies have revealed that skin T cells accumulate and maintain immune responses in the elderly. However, we questioned why these functional T cells fail to recognize and eliminate malignant cells, making elderly skin more prone to developing malignant tumors. To address this question, we examined the overall skin microenvironment in aging using the Nanostring nCounter system and 10x Xenium digital spatial RNA sequencing.

Parkinson's disease (PD) represents a progressive neurodegenerative disorder with escalating global burden, with mechanistic studies revealing α-synuclein propagation through gut-brain axis, mitochondrial defects, and neuroinflammatory cascades driven by genetic-environmental interplay. Recent advancements in diagnostic paradigms have successfully combined α-synuclein seed amplification assays with multimodal neuroimaging techniques, achieving an impressive diagnostic accuracy of 92% during the prodromal stages of disease. Phase II trials highlight disease-modifying potential of α-synuclein-targeting immunotherapies (40% reduction in motor decline) and LRRK2 kinase inhibitors showing blood-brain barrier penetration.

Microfluidics-assisted spatially barcoded microarray technology offers a high-throughput, low-cost approach towards spatial transcriptomic profiling. A uniform barcoded microarray is crucial for spatially unbiased mRNA analysis. However, non-specific adsorption of barcoding reagents in microchannels occurs during liquid transport, causing non-uniform barcoding in the chip's functional regions.

Plastics, particularly polystyrene (PS), are extensively used worldwide, especially in disposable packaging, which contributes to environmental pollution by generating microplastic particles. Herein, we investigated the pulmonary toxic effects of PS microplastics, focusing on airway inflammation and immune response. PS microplastic (50 nm to 1 μm) exposure was more likely to cause a severe pulmonary inflammatory response, particularly with smaller particle sizes.
