Blockade of interferon signaling decreases gut barrier integrity and promotes severe West Nile virus disease.

The determinants of severe disease caused by West Nile virus (WNV) and why only ~1% of individuals progress to encephalitis remain poorly understood. Here, we use human and mouse enteroids, and a mouse model of pathogenesis, to explore the capacity [...]

Autoantibodies neutralizing type I IFNs underlie West Nile virus encephalitis in ∼40% of patients.

Mosquito-borne West Nile virus (WNV) infection is benign in most individuals but can cause encephalitis in

Intestinal Candida albicans overgrowth in IgA deficiency.

Secretory IgA interacts with commensal bacteria, but its impact on human mycobiota ecology has not been widely explored. In particular, whether human IgA-deficiency is associated with gut fungal dysbiosis remains unknown. Our goal was to study the impact of IgA on [...]

Dissecting human population variation in single-cell responses to SARS-CoV-2.

Humans display substantial interindividual clinical variability after SARS-CoV-2 infection, the genetic and immunological basis of which has begun to be deciphered. However, the extent and drivers of population differences in immune responses to SARS-CoV-2 remain unclear. Here we report single-cell [...]

Human Genomics of COVID-19 Pneumonia: Contributions of Rare and Common Variants.

SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection is silent or benign in most infected individuals, but causes hypoxemic COVID-19 pneumonia in about 10% of cases. We review studies of the human genetics of life-threatening COVID-19 pneumonia, focusing on both [...]

Human genetic and immunological determinants of SARS-CoV-2 and Epstein-Barr virus diseases in childhood: Insightful contrasts.

There is growing evidence to suggest that severe disease in children infected with common viruses that are typically benign in other children can result from inborn errors of immunity or their phenocopies. Infection with severe acute respiratory syndrome coronavirus 2 [...]

Autoantibodies Neutralizing Type I IFNs in the Bronchoalveolar Lavage of at Least 10% of Patients During Life-Threatening COVID-19 Pneumonia.

Autoantibodies (auto-Abs) neutralizing type I interferons (IFNs) are found in the blood of at least 15% of unvaccinated patients with life-threatening COVID-19 pneumonia. We report here the presence of auto-Abs neutralizing type I IFNs in the bronchoalveolar lavage (BAL) of [...]

Publications 5 April 2023

Rare predicted loss-of-function variants of type I IFN immunity genes are associated with life-threatening COVID-19.

We previously reported that impaired type I IFN activity, due to inborn errors of TLR3- and TLR7-dependent type I interferon (IFN) immunity or to autoantibodies against type I IFN, account for 15-20% of cases of life-threatening COVID-19 in unvaccinated patients. [...]

Impact of SARS-CoV-2 infection and COVID-19 on patients with inborn errors of immunity.

Since the arrival of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in December 2019, its characterization as a novel human pathogen, and the resulting coronavirus disease 2019 (COVID-19) pandemic, over 6.5 million people have died worldwide-a stark and sobering reminder [...]
