Abstract
Induced pluripotent stem cells (iPSCs) are a valuable resource for neurological disease-modeling and drug discovery due to their ability to differentiate into neurons reflecting the genetics of the patient from which they are derived. iPSC-derived cultures, however, are highly variable due to heterogeneity in culture conditions. We investigated the effect of passage number on iPSC differentiation to optimize the generation of sensory neurons (iPSC-dSNs). Three iPSC lines reprogrammed from the peripheral blood of three donors were differentiated into iPSC-dSNs at passage numbers within each of the following ranges: low (5-10), intermediate (20-26), and high (30-38). Morphology and pluripotency of the parent iPSCs were assessed prior to differentiation. iPSC-dSNs were evaluated based on electrophysiological properties and expression of key neuronal markers. All iPSC lines displayed similar morphology and were similarly pluripotent across passage numbers. However, the expression levels of neuronal markers and sodium channel function analyses indicated that iPSC-dSNs differentiated from low passage numbers better recapitulated the sensory neuron phenotype than those differentiated from intermediate or high passage numbers. Our results demonstrate that lower passage numbers may be better suited for differentiation into peripheral sensory neurons.

PLoS Genet 2022; 18:e1009968.

Abstract
Taxane-induced peripheral neuropathy (TIPN) is a devastating survivorship issue for many cancer patients. In addition to its impact on quality of life, this toxicity may lead to dose reductions or treatment discontinuation, adversely impacting survival outcomes and leading to health disparities in African Americans (AA). Our lab has previously identified deleterious mutations in SET-Binding Factor 2 (SBF2) that significantly associated with severe TIPN in AA patients. Here, we demonstrate the impact of SBF2 on taxane-induced neuronal damage using an ex vivo model of SBF2 knockdown of induced pluripotent stem cell-derived sensory neurons. Knockdown of SBF2 exacerbated paclitaxel changes to cell viability and neurite outgrowth while attenuating paclitaxel-induced sodium current inhibition. Our studies identified paclitaxel-induced expression changes specific to mature sensory neurons and revealed candidate genes involved in the exacerbation of paclitaxel-induced phenotypes accompanying SBF2 knockdown. Overall, these findings provide ex vivo support for the impact of SBF2 on the development of TIPN and shed light on the potential pathways involved.

Abstract
Motor neuron loss or degeneration is the typical characteristic of amyotrophic lateral sclerosis (ALS), which often leads to weakness, paralysis, or even death. The underlying mechanisms of motor neuron degeneration and ALS progression remain elusive, and there is no effective treatment for ALS. The advances of stem cells and reprogramming techniques has made it possible to generate patient-specific motor neurons as cell models for studying disease mechanisms and drug discovery. This review comprehensively discusses recent approaches to generate motor neurons from stem cells and somatic cells and highlights the application of induced motor neurons to modeling ALS diseases, dissecting the pathogenesis, and screening new drugs. New perspectives are also discussed on generating patient-specific motor neuron subtypes that are affected by ALS or creating 3D spinal cord organoid models for better recapitulating and understanding ALS.

Abstract
Zika virus (ZIKV) is an emerging flavivirus that may be associated with congenital anomalies in infected fetuses and severe neurological and genital tract complications in infected adults. Currently, antiviral treatments to revert these ZIKV-induced complications are lacking. ZIKV infection has recently been suggested to upregulate the host unfolded protein response, which may contribute to the congenital neurological anomalies. As an extension from these findings, we thoroughly investigated the ZIKV-induced unfolded protein response using a combination of the neuronal cell line, induced pluripotent stem cell-derived human neuronal stem and progenitor cells, and an interferon receptor-deficient A129 mouse model. Our results revealed a critical contribution of the inositol-requiring enzyme-1 (IRE1) arm of the unfolded protein response to ZIKV-induced neurological and testicular complications. Importantly, the inhibition of the IRE1 signaling pathway activation with KIRA6 (kinase-inhibiting RNAse attenuator 6), a selective small molecule IRE1 inhibitor that promotes cell survival, potently reverted the ZIKV-induced perturbations of the key gene expressions associated with neurogenesis and spermatogenesis in vitro and in vivo, highlighting the potential of IRE1 inhibition as a novel host-targeting antiviral strategy in combating against ZIKV-induced neurological and testicular pathologies.

Abstract
Skin repair and reconstruction are important after severe wound and trauma. Keratinocyte stem cells (KSCs) in the basal layer of the epidermis can regrow the stratified epidermis but are almost depleted after skin injury. Thus, generating enough KSCs is indispensable for skin regeneration. Pluripotent stem cells such as ESC and iPSC can differentiate into KSCs, but their applications are challenged by ethical issues and risks of tumor formation. Lineage reprogramming from one cell type into another one makes it feasible to generate the desired cell type. Here, we develop a method to convert human fibroblasts into induced keratinocyte stem-like cells (iKSC) by coupling transient expression of reprogramming factors with a chemically defined culture medium, without the formation of iPSC. iKSC resemble normal KSC in the morphological and phenotypic features and can differentiate in vitro and regenerate stratified epidermis after transplantation in vivo. Therefore, iKSC may provide abundant cellular sources for skin repair and regeneration.
