Summary: Neurodegenerative dementias, including frontotemporal dementia, affect over 40 million people worldwide. The accumulation of tau protein in neurons and glial cells is a key feature of FTD, for which there is currently no cure. Research focuses on understanding the underlying mechanisms and potential therapeutic targets in these diseases.

Summary: Researchers have developed a method to efficiently transplant human induced pluripotent stem cell-derived microglia (hiPSC-MG) into mouse hippocampal slice cultures, achieving a high replacement rate. The transplanted microglia changed their morphology and phagocytosed cell debris when neuronal death was induced. This method provides a useful ex vivo tool for evaluating the properties of hiPSC-MG.

Summary: The study demonstrates the feasibility of culturing hiPSCs in 200 nL droplets on DMA, showing that they can attach to the MG-free surface and maintain good viability without spontaneous differentiation. Additionally, culturing hiPSCs in 200 nL droplets leads to higher expression of the pluripotency marker Nanog compared to 2 mL culture.

Summary: Brugada syndrome (BrS) is a rare inherited cardiac arrhythmogenic disease associated with an increased risk of ventricular fibrillation and sudden cardiac death. Most mutations are found in the SCN5A gene and result in an elevation of the ST segment in the right precordial leads V1 to V3. Human-induced pluripotent stem cell-derived cardiomyocytes have provided valuable insights into genotype-phenotype correlations and drug screening for BrS. The combination of CRISPR/Cas9-mediated genome editing and 3-dimensional engineered heart tissues holds promise for improving the diagnosis and treatment of BrS patients.

Summary: This study demonstrated that hiPSCs could form cartilage on Matrigel but not on laminin 511-E8, with differences observed in cell morphology and YAP activity. Transient knockdown of YAP around the start of chondrogenic differentiation successfully addressed the issue of cartilage formation from hiPSCs on laminin 511-E8.

Summary: Alzheimer's disease is a common neurodegenerative disorder, especially among the elderly population, with a significant impact on society and the economy. Genome-wide association studies have identified numerous genetic loci that are associated with increased risk of AD. The use of gene editing technology and hiPSCs can provide valuable insights into the role of immune-associated genetic risk variants in AD.

Summary: A protocol for differentiating suspensions of hiPSC spheroids into cardiomyocytes based on the GiWi method is introduced, and after optimization, the purity of hiPSC-CMs exceeded 98% with yields of about 1.5 million hiPSC-CMs per mL and less between-batch purity variability than hiPSC-CMs produced in 2D cultures. Additionally, the culture volume could be increased up to 10-fold to 30 mL with no need for re-optimization, suggesting that this method can serve as a framework for large-scale hiPSC-CM production.

Summary: Ichthyoses are a group of keratinization disorders caused by hereditary defects, with mutations in over 50 genes identified as causes. However, the high heterogeneity of the disease and challenges in establishing valid experimental models make research in this field difficult.

Summary: This study presents a forward programming protocol for generating microglia-like cells from human pluripotent stem cells. The generated cells exhibit similar characteristics to native microglia on a morphological, transcriptional, and functional level. The protocol can be used for reductionist studies and complex coculture systems, including 3D brain organoids, to investigate cellular interactions in healthy and diseased environments.

Summary: During space travel, astronauts face the challenge of adapting to microgravity and stressful living conditions. The impact of microgravity on organ development is not well understood, and this study used mouse mammary epithelial cells to investigate its effects. The results suggest that microgravity can cause abnormal changes in mammary epithelial cells and increase the risk of cancer.

Summary: This study investigated the effects of the NLRP3 inflammasome on airway epithelial injury and regeneration. The activation of NLRP3 inflammasome by silica disrupted the epithelial architecture, impaired mucociliary clearance, induced cellular hyperplasia, and inhibited organoid development. The abnormal differentiation and dysfunction of the airway epithelium mediated by NLRP3 inflammasome involved the NF-kappa B, Shh-Gli, and Wnt/beta-catenin pathways.

Summary: Fibrotic diseases are responsible for a third of global deaths, leading to organ remodeling and dysfunction. Despite the complications of organ transplantation, induced pluripotent stem cell (iPSC)-based therapy shows potential as a treatment option by replacing fibrotic organs. Recent studies have successfully differentiated iPSCs into fibrosis-relevant cell types with anti-fibrotic effects, providing promising precision treatments for organ-specific fibrosis. This review summarizes the potential, advantages, challenges, and future outlook of iPSC-based approaches in treating organ fibrosis.

Summary: Mesenchymal stem cells (MSCs) have great potential for cell therapy due to their immunomodulatory effects, but their clinical application is restricted by several factors. Induced pluripotent stem cells (iPSCs) offer a new source to generate MSCs, known as iMSCs, which may overcome technical and biological limitations and ethical concerns regarding human embryonic stem cells. Various differentiation methods for iPSCs into MSCs have been developed to meet clinical demands.

Summary: Parkinson's disease is a complex neurodegenerative disease influenced by both genetic and environmental factors. By reconstructing transcriptional regulatory networks of affected brain regions, potential therapeutic interventions have been identified through master regulator candidates. Using computational drug repositioning, new drugs have been suggested as potential therapies for Parkinson's disease.

Summary: The study demonstrates that NNMT protein expression is increased in the AD brain, mainly in cholinergic neurones, suggesting it may be a common feature in numerous neurodegenerative diseases. Confirming this overexpression in a larger AD patient cohort could lead to the development of NNMT-targeted therapeutics to slow or halt disease progression, in contrast to current symptomatic treatments for AD.

Summary: Parkinson's disease is characterized by alpha-synuclein deposition, which results in synaptic dysfunction and progressive neurodegeneration. This study found significantly decreased levels of NMNAT3 protein in the caudate nucleus of Parkinson's disease patients, which correlated with the amount of alpha-synuclein. The findings suggest that alterations in the NAD+ biosynthetic pathway are implicated in alpha-synuclein-mediated synaptopathy.
