Clonal inactivation of TERT impairs stem cell competition

Kazuteru Hasegawa, Yang Zhao, Alina Garbuzov, M. Ryan Corces et autres

Abstract Telomerase is intimately associated with stem cells and cancer, because it catalytically elongates telomeres—nucleoprotein caps that protect chromosome ends1. Overexpression of telomerase reverse transcriptase (TERT) enhances the proliferation of cells in a telomere-independent manner2–8, but so far, loss-of-function studies have provided …

Ancestry-based differences in the immune phenotype are associated with lupus activity

Samantha Slight‐Webb, Kevin L. Thomas, Miles Smith, Catriona A. Wagner et autres

Systemic lupus erythematosus (SLE) affects 1 in 537 Black women, which is >2-fold more than White women. Black patients develop the disease at a younger age, have more severe symptoms, and have a greater chance of early mortality. We used a multiomics …

Mass-Cytometry-Based Quantification of Global Histone Post-Translational Modifications at Single-Cell Resolution Across Peripheral Immune Cells in IBD

Lawrence Bai, Denis Đermadi, Laurynas Kalesinskas, Mai Dvorak et autres

BACKGROUND AND AIMS: Current understanding of histone post-translational modifications [histone modifications] across immune cell types in patients with inflammatory bowel disease [IBD] during remission and flare is limited. The present study aimed to quantify histone modifications at a single-cell resolution in IBD …

Crosstalk of Histone Modifications in the Healthy Human Immune System

Denis Đermadi, Laurynas Kalesinskas, Ananthakrishnan Ganesan, Alex Kuo et autres

ABSTRACT Chromatin remodeling through post-translational modifications of histone tails (HPTM) is fundamental for regulation and maintenance of DNA-centered processes. Systems level understanding of coordination and interactions between HPTMs and their impact on the functional state of the immune cells remain unexplored due …

New-onset IgG autoantibodies in hospitalized patients with COVID-19

Sarah E. Chang, Allan Feng, Wenzhao Meng, Sokratis A. Apostolidis et autres

COVID-19 is associated with a wide range of clinical manifestations, including autoimmune features and autoantibody production. Here we develop three protein arrays to measure IgG autoantibodies associated with connective tissue diseases, anti-cytokine antibodies, and anti-viral antibody responses in serum from 147 hospitalized …

Single-cell analysis of the epigenomic and transcriptional landscape of innate immunity to seasonal and adjuvanted pandemic influenza vaccination in humans

Florian Wimmers, Michele Donato, Alex Kuo, Tal Ashuach et autres

Abstract Emerging evidence indicates a fundamental role for the epigenome in immunity. Here, we used a systems biology approach to map the epigenomic and transcriptional landscape of immunity to influenza vaccination in humans at the single-cell level. Vaccination against seasonal influenza resulted …

Clonal inactivation of telomerase promotes accelerated stem cell differentiation

Kazuteru Hasegawa, Yang Zhao, Alina Garbuzov, M. Ryan Corces et autres

Summary Telomerase is intimately associated with stem cells and upregulated in cancer, where it serves essential roles through its catalytic action in elongating telomeres, nucleoprotein caps that protect chromosome ends 1 . Overexpression of the telomerase reverse transcriptase (TERT) enhances cell proliferation …

New-Onset IgG Autoantibodies in Hospitalized Patients with COVID-19

Sarah E. Chang, Allan Feng, Wenzhao Meng, Sokratis A. Apostolidis et autres

Abstract Coronavirus Disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), is associated with a wide range of clinical manifestations, including autoimmune features and autoantibody production. We developed three different protein arrays to measure hallmark IgG autoantibodies associated with Connective …
