Multiple sclerosis (MS) is a chronic autoimmune and neurodegenerative disease that results in immune cell infiltration of the central nervous system (CNS) and demyelination in young adults. Substantial progress has been made in developing disease modifying therapies for people with relapsing-remitting MS, but options remain limited for people with primary progressive MS (PPMS). PPMS accounts for ∼15% of MS diagnoses. Herein, we generated a human induced pluripotent stem cell line (hiPSC) from a person with clinically definite PPMS. This disease-specific hiPSC line will be useful for studying PPMS in vitro, allowing the generation of immune and CNS cell types.

Mouse embryonic fibroblasts (MEFs) have been widely used as feeder cells in embryonic stem cell cultures because they can mimic the embryonic microenvironment. Milk fat globule-epidermal growth factor 8 (MFGE8) is expressed during mouse gonadal development, 10.5-13.

Aims: Alexander disease (AxD) is a leukodystrophy caused by mutations in the astrocytic filament gene GFAP. There are currently no effective treatments for AxD. Previous studies have rarely established AxD models with the patient's original GFAP mutations.

Background And Aims: Metabolic Dysfunction Associated Steatotic Liver Disease (MASLD) is reversible at early stages, making early identification of high-risk individuals clinically valuable. Previously, we demonstrated that patient-derived induced pluripotent stem cells (iPSCs) harboring MASLD DNA risk variants exhibit greater oleate-induced intracellular lipid accumulation than those without these variants. This study aimed to develop an iPSC-based MASLD risk predictor using functional lipid accumulation assessments.

Background: Deficiency in the lysosomal enzyme, glucocerebrosidase (GCase), caused by mutations in the GBA1 gene, is the most common genetic risk factor for Parkinson's disease (PD). However, the consequence of reduced enzyme activity within neural cell sub-types remains ambiguous. Thus, the purpose of this study was to define the effect of GCase deficiency specifically in human astrocytes and test their non-cell autonomous influence upon dopaminergic neurons in a midbrain organoid model of PD.

Gene syntax-the order and arrangement of genes and their regulatory elements-shapes the dynamic coordination of both natural and synthetic gene circuits. Transcription at one locus profoundly impacts the transcription of nearby adjacent genes, but the molecular basis of this effect remains poorly understood. Here, using integrated reporter circuits in human cells, we show that supercoiling-mediated feedback regulates expression of adjacent genes in a syntax-specific manner.
