Abstract
Each year in the United States, ~50% of adults ≥18 years old are vaccinated against influenza viruses, with protective efficacy averaging 40.5% over the past 20 years. To model annual seasonal influenza, a cohort of 74 adults, who were unscreened for preexisting A/H1N1 immunity and half of whom were recently immunized with licensed QIV (mean of 64 days), were challenged with A/H1N1 influenza virus. Transcriptomic, proteomic, and VDJ repertoire analyses were performed on nasal and peripheral blood samples from participants to identify nasal mucosal and systemic immune responses that correlated with viral shedding and immune correlates of protection. Viral-shedding participants showed increased T cell, but not B cell, VDJ diversity with expansion of low-frequency B cell clones postchallenge, including broadly neutralizing motifs. Nonshedding participants demonstrated decreased clonality and increased richness of B and T cell VDJ clones, increased preinoculation nasal mucosal immune gene and serum protein expression, and increased ex vivo peripheral blood mononuclear cell responses. Nasal mucosal responses in participants shedding virus for 2 or more days showed higher early viral loads and exhibited stronger induction of antiviral responses compared with those in participants who shed virus for 1 day. Last, participants with a single day of viral shedding were three times more likely to be female. These data shed light on the complex immune responses in the nasal mucosa and the periphery after influenza vaccination and infection, which will be critical for next-generation vaccine development.
期刊介绍:
Science Translational Medicine is an online journal that focuses on publishing research at the intersection of science, engineering, and medicine. The goal of the journal is to promote human health by providing a platform for researchers from various disciplines to communicate their latest advancements in biomedical, translational, and clinical research.
The journal aims to address the slow translation of scientific knowledge into effective treatments and health measures. It publishes articles that fill the knowledge gaps between preclinical research and medical applications, with a focus on accelerating the translation of knowledge into new ways of preventing, diagnosing, and treating human diseases.
The scope of Science Translational Medicine includes various areas such as cardiovascular disease, immunology/vaccines, metabolism/diabetes/obesity, neuroscience/neurology/psychiatry, cancer, infectious diseases, policy, behavior, bioengineering, chemical genomics/drug discovery, imaging, applied physical sciences, medical nanotechnology, drug delivery, biomarkers, gene therapy/regenerative medicine, toxicology and pharmacokinetics, data mining, cell culture, animal and human studies, medical informatics, and other interdisciplinary approaches to medicine.
The target audience of the journal includes researchers and management in academia, government, and the biotechnology and pharmaceutical industries. It is also relevant to physician scientists, regulators, policy makers, investors, business developers, and funding agencies.
