Monoallelic expression can govern penetrance of inborn errors of immunity.

Nature

January 2025

Columbia Center for Genetic Errors of Immunity, Vagelos College of Physicians and Surgeons, Columbia University, New York, NY, USA.

Inborn errors of immunity (IEIs) are genetic disorders that underlie susceptibility to infection, autoimmunity, autoinflammation, allergy and/or malignancy. Incomplete penetrance is common among IEIs despite their monogenic basis. Here we investigate the contribution of autosomal random monoallelic expression (aRMAE), a somatic commitment to the expression of one allele, to phenotypic variability observed in families with IEIs.

To explore the potential efficacy of early initiation of intravenous cyclophosphamide (IVCPA), we reviewed consecutive four cases of super-refractory cryptogenic-new onset refractory status epilepticus (C-NORSE) between 2015 and 2023. We compared functional outcomes at 3 months and 1 year after the onset between patients who received IVCPA within 20 days (early-treated) and those who received it later (late-treated). All patients (median age: 43 years) had a prodromal fever.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes severe illness and mortality in patients with immunodeficiency. Although vaccination has been recommended, the induction of protective antibodies by immunization, and thus the disease-preventive effect, has proven insufficient in immunodeficient patients, especially in those with predominantly antibody deficiency. A monoclonal antibody combination of tixagevimab and cilgavimab (TIX/CIL) was developed as a pre-exposure prophylaxis (PrEP).

Article Synopsis
  • Red complex bacteria are highly virulent in periodontal disease, and this study focused on their relationships with other oral bacteria in older Japanese individuals.
  • Polymerase chain reaction was used to analyze dental plaque from 116 subjects, finding that individuals positive for red complex bacteria had significantly higher detection rates of certain periodontal pathogens compared to those who were negative.
  • The findings indicate that individuals harboring all three red complex species have a unique oral microbiome, showcasing greater α-diversity and lower β-diversity, suggesting they may be more prone to developing periodontal disease.
