Mucosal Associated Invariant T (MAIT) Cell Responses Differ by Sex in COVID-19.
Abstract
Sexual dimorphisms in immune responses contribute to coronavirus disease 2019 (COVID-19)
outcomes, yet the mechanisms governing this disparity remain incompletely understood.
We carried out sex-balanced sampling of peripheral blood mononuclear cells from confirmed
COVID-19 inpatients and outpatients, uninfected close contacts, and healthy controls
for 36-color flow cytometry and single cell RNA-sequencing. Our results revealed a
pronounced reduction of circulating mucosal associated invariant T (MAIT) cells in
infected females. Integration of published COVID-19 airway tissue datasets implicate
that this reduction represented a major wave of MAIT cell extravasation during early
infection in females. Moreover, female MAIT cells possessed an immunologically active
gene signature, whereas male counterparts were pro-apoptotic. Collectively, our findings
uncover a female-specific protective MAIT profile, potentially shedding light on reduced
COVID-19 susceptibility in females.

Daniel Raphael Saban
Associate Professor of Ophthalmology
My broad research interests are the cellular and molecular mechanisms that contribute
to pathogenic immunity in ophthalmic disease and vision loss. My studies are currently
focused on dendritic cells (DC), a unique leukocyte population of antigen presenting
cells required for both initiating and determining the type of immune response generated.
These cells contribute to the maintenance of health versus immunity in ocular disease.

Professor in Medicine
Dr. Sempowski earned his PhD in Immunology from the University of Rochester and was
specifically trained in the areas of inflammation, wound healing, and host response
(innate and adaptive). Dr. Sempowski contributed substantially to the field of lung
inflammation and fibrosis defining the roles of pulmonary fibroblast heterogeneity
and CD40/CD40L signaling in regulating normal and pathogenic lung inflammation. During
his postdoctoral training with Dr. Barton F. H

Adjunct Professor in the Department of Pathology
Dr. Shen’s research interests lie at precision medicine and systems biology. His lab
integrates engineering, computational and biological techniques to study cancer, stem
cells, microbiota and the nervous system in the gut. This multidisciplinary work has
been instrumental in initiating several translational clinical trials in precision
therapy. He is the director of the Woo Center for Big Data and Precision Health (DAP)
and a core member of the Center for Genomics and Computational Biolog
Ephraim Tsalik
Adjunct Associate Professor in the Department of Medicine
My research at Duke has focused on understanding the dynamic between host and pathogen
so as to discover and develop host-response markers that can diagnose and predict
health and disease. This new and evolving approach to diagnosing illness has the
potential to significantly impact individual as well as public health considering
the rise of antibiotic resistance.
With any potential infectious disease diagnosis, it is difficult, if not impossible,
to determine at the time of pre
