Human iPSC-derived microglia are genetically relevant to Alzheimer’s disease

Project description:Microglia is a primary brain immune cell type that has been implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer’s disease (AD) and neurodevelopmental disorders such as schizophrenia. Generating microglia from human induced pluripotent stem cells (hiPSC) has become an attractive approach to study the microglia-mediated causal mechanism of AD. Among other methods, Brownjohn et al. recently developed a particularly efficient and simple hiPSC-derived microglia (iMG) protocol. However, the transferability of this method to other labs, the transcriptomic similarity of these iMG to primary adult microglia, and their genetic relevance to AD remain unclear. With two hiPSC lines, we demonstrated that the Brownjohn method can efficiently give rise to iMG that were morphologically and functionally like microglia. Our pure iMG were also transcriptionally similar to previously reported iMG lines, as well as fetal and adult microglia. More importantly, we further showed the genetic relevance of iMG to AD using cell type-specific gene expression to partition disease heritability. Contrasting with neuronal and immune cell types, our iMG and several primary microglia and microglia-like cell types were all significantly enriched for AD relevant GWAS loci. These results supported the use of iMG as a valid human cellular model for understanding AD disease progression and a feasible mechanism for generation of AD patient-specific cell types for more precise in vitro analyses, and potentially more effective clinical care.

An integrated toolkit for human microglia functional genomics

Project description:Microglia, the brain’s resident immune cells, play vital roles in brain development, and disorders like Alzheimer’s disease (AD). Human iPSC-derived microglia (iMG) provide a promising model to study these processes. However, existing iMG generation protocols face challenges, such as prolonged differentiation time, lack of detailed characterization, and limited gene function investigation via CRISPR-Cas9. In this study will generated iMG from human iPSCs using our newly developed protocol. We used single cell RNA-Seq to study the transcriptomic profiles of our newly formed iMG. The single cell RNA-Seq data under this accession is from wild type iMG (Hashtag 7) and OTHER KO iMG (Hashtag 8)

Efficient conversion of human induced pluripotent stem cells into microglia by defined transcription factors

Project description:Microglia, the immune cells of the central nervous system (CNS), play critical roles in brain physiology and pathology. We report a novel approach that produces within ten days the differentiation of human induced pluripotent stem cells (hiPSCs) into microglia (iMG) by forced expression of both SPI1 and CEBPA. High-level expression of the main microglial markers and the purity of the iMG cells were confirmed by RT-qPCR, immunostaining and flow cytometry analyses. Whole transcriptome analysis demonstrated that these iMGs resemble human fetal/adult microglia but not human monocytes. Moreover, these iMGs exhibited appropriate physiological functions, including various inflammatory responses, ADP/ATP-evoked migration and phagocytic ability. When co-cultured with hiPSC-derived neurons (iNs), the iMGs respond and migrate toward injured neurons. This study has established a protocol for the rapid conversion of hiPSCs into functional iMGs, which should facilitate functional studies of human microglia using different disease models and also help with drug discovery.

Enhancing human iPSC-derived retinal organoids by incorporating microglia-like cells

Project description:Microglia are the primary resident immune cells in the retina. They regulate neuronal survival and synaptic pruning, which makes them essential for normal development. Following injury, they mediate adaptive responses and under pathological conditions can trigger neurodegeneration exacerbating the effect of the disease. Retinal organoids derived from human induced pluripotent stem cells (hiPSCs) are increasingly used for a range of applications, including disease modelling, development of new therapies and in the study of retinogenesis. Despite their close resemblance to the in vivo retina, they lack some key physiological features including immune cells. To enhance the retinal organoid model, we engineered an hiPSC co-culture system containing the hiPSC-derived retinal organoids and hiPSC-derived microglia-like (iMG) cells and tested their retinal invasion capacity and function. We incorporated iMG into retinal organoids at 13 weeks and tested their effect on function and development at 15 and 21.5 weeks of differentiation. Our key findings showed that iMG cells were able to respond to endotoxin challenge in monocultures and when co-cultured with the organoids. Single cell RNA-Seq transcriptomic analyses, protein expression, electron microscopy imaging and electrophysiological recordings showed that retinal organoids developed normally, expressed key markers, and retained their ability to generate spiking activity in response to light. Thus, this new co-culture immunocompetent in vitro retinal model provides a platform with greater relevance to the in vivo human retina.

Permanently Re-programmed Microglia in Spinal Cord Injury Contribute to Functional Recovery

Project description:Microglia are resident myeloid cells of the central nervous system (CNS). Recently, single-cell RNA sequencing (scRNAseq) has enabled description of a disease-associated subtype of microglia (DAM) with a role in neurodegeneration and demyelination. In this study we use scRNAseq to investigate the temporal dynamics of immune cells harvested from the epicenter of traumatic spinal cord injury (SCI). As a consequence of SCI, homeostatic microglia undergo permanent transcriptional re-programming into a subtype of microglia with striking similarities to previoysly reported DAM as well as a distinct microglial state found during development. Using a microglia depletion model we showed that DAM in SCI are derived from homeostatic microglia and strongly enhance recovery of hind limb locomotor function following injury.
