Somali immigrants are one of the largest African populations to resettle in the United States since 1990. There is an emerging literature base of disease-specific studies among Somali immigrants. However, we are aware of no studies on the health priorities for Somalis from the community's perspective. Somali adults in Minnesota completed a survey conducted by a community-based participatory research partnership on individual and community health priorities. Data were reported as counts and frequencies. 646 participants completed the survey. The most important health issues for individuals and their families were health behaviors (22.7%), diabetes (18.2%), and hypertension (14.4%), while those of the community were diabetes (22.5%), hypertension (18.8%) and weight (15.9%). This study found a significant overlap of health priorities among Somali individuals and their families compared to the community. These health priorities underscore the need to focus on non-communicable diseases among Somali immigrants.A stable, rapid and effective neural differentiation method is essential for the clinical applications of human embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs) in treating neurological disorders and diseases. selleck Herein, we established a novel and robust monolayer differentiation method to produce functional neural progenitor cells (NPCs) from human ESC/iPSCs on Type I Collagen. The derived cells not only displayed the requisite markers, but also behaved similarly to classic NPCs both in vitro and in vivo. Upon transplantation into traumatic brain injury model, the derived NPCs facilitated recovery from injury. We also found that SMAD signaling stayed down throughout the differentiation process on Type I Collagen, and the pluripotent signals were rapidly downregulated along with raising up of neural early markers on the third day. Meanwhile, ATAC-seq data showed the related mediation of distinct transcriptome and global chromatin dynamics during NPC induction. Totally, our results thus provide a convenient way to generate NPCs from human ESC/iPSCs for neural diseases' treatment.Cytotoxic T cells targeting cancer neoantigens harboring driver mutations can lead to durable tumor regression in an HLAI-dependent manner. However, it is difficult to extend the population of patients who are eligible for neoantigen-based immunotherapy, as immunogenic neoantigen-HLA pairs are rarely shared across different patients. Thus, a way to find other human leukocyte antigen (HLA) alleles that can also present a clinically effective neoantigen is needed. Recently, neoantigen-based immunotherapy targeting the KRAS G12D mutation in patients with HLA-C*0802 has shown effectiveness. In a proof-of-concept study, we proposed a combinatorial strategy (the combination of phylogenetic and structural analyses) to find potential HLA alleles that could also present KRAS G12D neoantigen. Compared to in silico binding prediction, this strategy avoids the uneven accuracy across different HLA alleles. Our findings extend the population of patients who are potentially eligible for immunotherapy targeting the KRAS G12D mutation. Additionally, we provide an alternative way to predict neoantigen-HLA pairs, which maximizes the clinical usage of shared neoantigens.Pulmonary surfactant is a lipid-protein complex secreted by alveolar type II epithelial cells and is essential for the maintenance of the delicate structure of mammalian alveoli to promote efficient gas exchange across the air-liquid barrier. The Golgi apparatus plays an important role in pulmonary surfactant modification and secretory trafficking. However, the physiological function of the Golgi apparatus in the transport of pulmonary surfactants is unclear. In the present study, deletion of GM130, which encodes for a matrix protein of the cis-Golgi cisternae, was shown to induce the disruption of the Golgi structure leading to impaired secretion of lung surfactant proteins and lipids. Specifically, the results of in vitro and in vivo analysis indicated that the loss of GM130 resulted in trapping of Sftpa in the endoplasmic reticulum, Sftpb and Sftpc accumulation in the Golgi apparatus, and an increase in the compensatory secretion of Sftpd. Moreover, global and epithelial-specific GM130 knockout in mice resulted in an enlargement of alveolar airspace and an increase in alveolar epithelial autophagy; however, surfactant repletion partially rescued the enlarged airspace defects in GM130-deficient mice. Therefore, our results demonstrate that GM130 and the mammalian Golgi apparatus play a critical role in the control of surfactant protein secretion in pulmonary epithelial cells.This was an observational cross-sectional study which was done to assess the expression profile of STATs and SOCS genes in cystic fibrosis. The mRNA was isolated from peripheral blood mononuclear cells of CF patients in exacerbation, colonization and post exacerbation phases of the disease. The relative gene expression level for SOCS 1, -3, -5 and STAT 1, -3,-4,-6 genes was quantified by Real-time PCR. The levels of IL-6 were also measured in the serum by ELISA. The expression of the Th1 pathway associated genes (SOCS1, SOCS5, STAT4 and STAT1) was downregulated while the expression of Th2/Th17 pathway genes (SOCS3, STAT3, STAT6) was upregulated in both exacerbation and colonization phases as compared to healthy controls. The serum levels of IL-6 were also elevated in both the disease groups. After antibiotic treatment, the expression of SOCS5 and STAT4 was increased while the expression of rest of the genes showed downregulation which shows a shift in immune response from Th2/Th17 to Th1. Our results suggest that infection alters the cytokine signaling pathway through modulation of STATs and SOCS genes which is not able to regulate the overstimulation of cytokine signaling further leading to chronic inflammation in CF.The coronavirus disease (COVID-19), caused by SARS-CoV-2 infection, accounts for more than 2.4 million deaths worldwide, making it the main public health problem in 2020. Purinergic signaling is involved in the pathophysiology of several viral infections which makes the purinergic system a potential target of investigation in COVID-19. During viral infections, the ATP release initiates a cascade that activates purinergic receptors. This receptor activation enhances the secretion of pro-inflammatory cytokines and performs the chemotaxis of macrophages and neutrophils, generating an association between the immune and the purinergic systems. This review was designed to cover the possible functions of purinergic signaling in COVID-19, focusing on the possible role of purinergic receptors such as P2X7 which contributes to cytokine storm and inflammasome NLRP3 activation and P2Y1 that activates the blood coagulation pathway. The possible role of ectonucleotidases, such as CD39 and CD73, which have the function of dephosphorylating ATP in an immunosuppressive component, adenosine, are also covered in detail.
