The MHC region has undergone a complex series of duplications in macaques relative to humans. Steady-state RNA levels of macaque MHC class I and class II transcripts vary over several orders of magnitude in whole blood and bulk PBMC. In this study, we compared transcript levels in untreated control PBMC with transcript levels after T cell activation, treatment with pro-inflammatory cytokines, or treatment with anti-inflammatory cytokines. Transcript levels for several minor MHC alleles were preferentially induced in monocytes and dendritic cells after treatment with pro-inflammatory cytokines or T cell activation.

Among these, long non-coding RNAs (lncRNAs) have been implicated in various biological functions, including the control of gene expression and translation. The central nervous system (CNS) harbors a diverse array of lncRNA transcripts, yet the functions of many remain largely unexplored. In this study, we employed FANS with total RNA-sequencing and single-nuclei RNA sequencing approaches using human and mouse brain tissue to identify novel lncRNAs specific to neurons, and potentially associated with neurodegenerative diseases. We discovered a novel brain-specific lncRNA, the we named ‘NeuID’, that is specifically expressed in neuronal cells in the mouse and human brains. NeuID expression was found to be reduced in the brains of Alzheimer’s disease (AD) patients. Knockdown (KD) of NeuID resulted in the downregulation of synaptic plasticity genes. Additionally, NeuID KD led to decreased dendritic spine density and reduced neuronal network activity in MEA recordings. Furthermore, we demonstrate that NeuID interacts with EZH2, a component of the PRC2 complex, and mediates the h3k27me3 levels of Olig2 transcription factor. Notably, CRISPRa mediated overexpression of NeuID resulted in the rescue of functional impairment caused by AD-related pathological Aβ oligomers. Overall, our findings identify a novel brain and neuron-exclusive lncRNA that regulates neuronal function, is dysregulated in AD, and might be a potential therapeutic target against neuronal pathology in AD.

- 📝 描述:Contributors : Lai-Ying Zhang ; Peter C Allen ; Viviana P Lutzky ; Simon H Apte ; Penelope L Groves ; Maxine E Tan ; Tharushi De Silva ; Quan H Nguyen ; Joseph E Powell ; Daniel C Chambers ; Brendan J O’SullivanSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensRATIONALE: Interstitial lung diseases (ILDs) encompass a diverse range of fibrotic conditions and contribute to significant respiratory morbidity and mortality. Assessment of the cellular composition of bronchoalveolar lavage (BAL) fluid is an important diagnostic test in people presenting with ILD, but BAL cellularity remains relatively uncharacterized at single-cell resolution. OBJECTIVE: To characterize immune cell populations in BAL across different ILDs and investigate the impact of shortened peripheral blood leukocyte telomere length on BAL immune profiles. METHODS: Single-cell RNA sequencing and downstream analysis were performed on BAL samples from 25 patients with various ILDs, including idiopathic pulmonary fibrosis (IPF), hypersensitivity pneumonitis, sarcoidosis, and silicosis. Both normal-telomere and short-telomere patients were included. Additionally, we integrated our findings with IPF genome-wide association study (GWAS) data. RESULTS: We identified sixteen distinct cell populations in BAL with notable differences across ILD subtypes. Analysis revealed six monocyte-like macrophage (MLM) subclusters following divergent trajectories: inflammatory CXCL10hi MLMs predominated in hypersensitivity pneumonitis, while pro-fibrotic SPP1hi MLMs were significantly expanded in IPF. Short-telomere patients demonstrated an increased proportion of pro-fibrotic SPP1hi MLMs with enhanced expression of fibrotic genes compared to patients with normal telomere length. Integration with genomic data confirmed that SPP1hi and CCL2hi MLM subclusters harbour cells with the highest IPF disease relevance scores. CONCLUSION: BAL-derived transcriptomics reveals distinct myeloid subpopulations across ILD subtypes, with specific populations associated with disease pathogenesis. These findings provide insight into ILD pathogenesis, motivate the development of more sophisticated diagnostic tests using BAL sampling, and highlight specific myeloid subpopulations as potential therapeutic targets.

6. GSE318189 孕期和产后母体表观遗传衰老指标的轨迹
- ✍️ 作者:未知作者
- 🏷️ 关键词:aging、epigenetic
- 📝 描述:Contributors : Laura Etzel ; Idan Shalev ; Patricia Garrett-PetersSeries Type : Methylation profiling by genome tiling arrayOrganism : Homo sapiensPregnancy has been proposed as a biological “stress test” that may transiently accelerate maternal biological aging, followed by partial recovery in the postpartum period; however, longitudinal evidence characterizing these trajectories remains limited. This longitudinal study followed 130 women across mid to late pregnancy, early postpartum (6–9 months), and later postpartum (36–43 months) to characterize nonlinear changes in multiple markers of biological aging. Biological aging was assessed using complementary indicators, including telomere length, DNA methylation–based epigenetic aging measures, and pace-of-aging metrics. Genome-wide DNA methylation data were generated from maternal biospecimens using the Illumina Infinium MethylationEPIC v2.0 BeadChip to support derivation of epigenetic aging measures and evaluation of longitudinal methylation dynamics. Generalized additive mixed models were used to examine within-person changes over time. Results indicated relative stability or slowing of biological aging during early postpartum, followed by marker-specific patterns of stabilization or decline during later postpartum. Subsequent pregnancy during the later postpartum period was associated with shorter telomere length and altered recovery trajectories, including accelerated pace of aging among women who became pregnant again. Together, these findings suggest that while partial recovery of biological aging markers may occur following pregnancy, such recovery may be sensitive to additional reproductive demands. The DNA methylation data deposited here support longitudinal analyses of maternal biological aging across pregnancy and postpartum and provide a resource for future studies examining reproductive influences on epigenetic aging processes.

Notably, women co-infected with HPV and human immunodeficiency virus type 1 (HIV-1) have a six-fold higher lifetime risk of developing cervical cancer compared to those without HIV, even when adhering to antiretroviral therapy (ART) and achieving T-cell reconstitution. While chronic HIV-1 infection is known to cause inflammation, how paracrine signals from immune cells alter signaling in cervical cells remain poorly understood. To address this, we conducted global transcriptomics analysis on cervical swabs from Kenyan women with HPV, stratified by HIV-1 and cancer status. Strikingly, women with HIV-1 showed cancer-like gene expression patterns in non-cancerous cervical epithelial cells. Complementary global mass spectrometry (MS) proteomics of cervical cells exposed to the secretome of HIV-1–infected primary CD4+ T-cells revealed altered expression of proteins in MAPK, PI3K-AKT, and β-catenin signaling pathways. Integrative network analyses of transcriptomic and proteomic datasets revealed that HIV-1 altered gene expression in key pathways known to drive cervical cancer, including genes commonly mutated in HIV-1-naïve disease. Notably, IRS-1, a key PI3K-AKT pathway activator, was found to be consistently upregulated in both participant samples and cell culture models, as were interferon-stimulated genes. Phosphoproteomics MS analysis confirmed PI3K-AKT pathway activation in cervical cells exposed to conditioned media from HIV-1-infected T-cells. Together, our findings uncover how HIV-1 reshapes cervical cell signaling via paracrine mechanisms and highlights the PI3K pathway as a potential therapeutic target in HIV-associated cervical cancer.

9. GSE278193 NuRD复合物在CTCF位点重塑染色质环境和维持基因组结构中的关键作用[mESC ChIP-seq]
- ✍️ 作者:未知作者
- 🏷️ 关键词:ChIP-seq、genome
- 📝 描述:Contributors : Jian Yan ; Xi Wang ; Wenju Sun ; Nan WuSeries Type : Genome binding/occupancy profiling by high throughput sequencingOrganism : Mus musculusCCCTC-binding factor (CTCF) is an evolutionarily conserved transcription factor with diverse regulatory roles. Around stable CTCF binding sites, nucleosomes are highly ordered and DNA methylation is reduced, yet the mechanisms establishing and maintaining this epigenetic environment remain unclear. Utilizing an innovative eBioID method, we identified that virtually all subunits of the nucleosome remodeling and deacetylase (NuRD) complex are associated with CTCF in cells. Further analyses revealed that the NuRD complex is necessary for the chromatin binding of CTCF, and emerges as a novel regulator of the genome architecture. Additionally, we discovered that MBD3-NuRD facilitates the recruitment of TET demethylases to CTCF sites, initiating local DNA demethylation essential for the activation of adjacent gene expression. Embryonic stem cells deficient in the NuRD complex showed impaired lineage commitment. In summary, this study elucidates a mechanism illustrating the interplay between CTCF binding and the epigenome including 3D genome organization and DNA methylation, with the NuRD complex serving as an indispensable mediator.
