Modeling human adaptive immune responses with tonsil organoids (Publications)
Most of what we know about adaptive immunity has come from inbred mouse studies, using methods that are often difficult or impossible to confirm in humans. In addition, vaccine responses in mice are o
Case-control study of individuals with discrepant nucleocapsid and spike protein SARS-CoV-2 IgG results (Publications)
BACKGROUND: Laboratory-based methods for SARS-CoV-2 antibody detection vary widely in performance. However, there are limited prospectively-collected data on assay performance, and minimal clinical in
Global, regional, and national burden of mortality associated with short-term temperature variability from 2000-19: a three-stage modelling study (Publications)
BACKGROUND: Increased mortality risk is associated with short-term temperature variability. However, to our knowledge, there has been no comprehensive assessment of the temperature variability-related
Long-term exposure to low ambient air pollution concentrations and mortality among 28 million people: results from seven large European cohorts within... (Publications)
BACKGROUND: Long-term exposure to ambient air pollution has been associated with premature mortality, but associations at concentrations lower than current annual limit values are uncertain. We analys
Outdoor air pollution exposure and cognitive performance: findings from the enrolment phase of the CONSTANCES cohort (Publications)
