Inactivation of cytidine triphosphate synthase 1 prevents fatal auto-immunity in mice

Nature Communications
De novo synthesis of the pyrimidine, cytidine triphosphate (CTP), is crucial for DNA/RNA metabolism and depends on the CTP synthetases, CTPS1 and −2. Partial CTPS1 deficiency in humans has previously been shown to lead to immunodeficiency, with impaired ...

Clinical Characteristics and Concordance of Anti‐MDA5 Antibodies: A Multicenter Australian Study

Arthritis Care &Research, EarlyView.
Objective In Australia, anti‐MDA5 antibodies are exclusively tested by a line immunoblot assay (LIA). The clinical concordance of an LIA‐positive anti‐MDA5 result is unclear. We aimed to describe the clinical features and determine the clinical concordance of patients with anti‐MDA5 antibodies. Methods Electronic records of a multisite cohort (patients

CTPS2 regulates CTP synthetase activity by interacting with CTPS1

Life Science Alliance
The human CTP synthetases 1 and 2 associate together and co-localize in large filament–cytoophidium structures. CTPS1 and CTPS2 association results in enzymatic modulation independently of cytoophidia revealing a new regulation mechanism of CTP ...

Telomeres and Viruses: Common Themes of Genome Maintenance

Frontiers in Oncology, 2012
Genome maintenance mechanisms actively suppress genetic instability associated with cancer and aging. Some viruses provoke genetic instability by subverting the host’s control of genome maintenance.

Clonal origin of Epstein-Barr virus-infected T/NK-cell subpopulations in chronic active Epstein-Barr virus infection [PDF]

, 2010
Clonal expansion of Epstein-Barr virus (EBV) infected B-cells occasionally occurs in immunocompromized subjects. EBV-infected T/natural killer (NK)-cells proliferate in patients with chronic active EBV infection (CAEBV) that is a rare mononucleosis ...

Single‐Cell Transcriptomic Profiling Identifies B Cell‐Intrinsic Dysregulation of Sphingolipid Biosynthesis and Could Be Improved by Inhibiting UGCG in Primary Immune Thrombocytopenia

Advanced Science, EarlyView.
This study generates the single‐cell atlas of pathogenic B‐cell subset Bc‐5 in ITP. It identifies RUNX3 as a key survival regulator and uncovers sphingolipid‐driven metabolic reprogramming, validating UGCG inhibition as a therapeutic candidate and building a valuable resource for ITP mechanistic and therapeutic exploration.

Differences in Epstein-Barr Virus Characteristics and Viral-Related Microenvironment Could Be Responsible for Lymphomagenesis in Children

Pathogens, 2020
In Argentina, Epstein-Barr virus (EBV) presence is associated with Hodgkin lymphoma (HL) in patients younger than 10 years, suggesting a relationship between low age of EBV infection and HL.
