Immune transcriptomes of highly exposed SARS-CoV-2 asymptomatic seropositive versus seronegative individuals from the Ischgl community

Project description:SARS-CoV-2 infection ranges from asymptomatic to severe with lingering symptomatology in some. This prompted investigation of whether or not asymptomatic disease results in measurable immune activation post-infection. Immune activation following asymptomatic SARS-CoV-2 infection was characterized through a comparative investigation of the immune cell transcriptomes from 43 asymptomatic seropositive and 52 highly exposed seronegative individuals from the same community four to six weeks following a superspreading event. Few of the 95 individuals had underlying health issues. One seropositive individual reported Cystic Fibrosis and one individual reported Incontinentia pigmenti. No evidence of immune activation was found in asymptomatic seropositive individuals with the exception of the Cystic Fibrosis patient. There were no statistically significant differences in immune transcriptomes between asymptomatic seropositive and highly exposed seronegative individuals. Four positive controls, mildly symptomatic seropositive individuals whose blood was examined three weeks following infection, showed immune activation. Negative controls were four seronegative individuals from neighboring communities without COVID19. All individuals remained in their usual state of health through a five-month follow-up after sample collection. In summary, whole blood transcriptomes identified individual immune profiles within a community population and showed that asymptomatic infection within a super-spreading event was not associated with enduring immunological activation.

Microarray analysis of dengue seronegative or seropositive volunteers that received the tetravalent dengue vaccine TAK-003

Project description:Samples were collected from the DEN210 study, a phase IIb clinical trial evaluating two doses of TAK003, a tetravalent dengue vaccine, administered 90 days apart in healthy adult participants with and without prior DENV infection (NCT03746015). RNA was extracted from whole blood collected in Paxgene tubes from volunteers at Day 1, 4, 6, 90, 94 and 96. Day 1 and Day 90 samples were collected prior to administration of first and second TAK-003 vaccine dose. We performed gene expression analysis in dengue seronegative and seropositive individuals over time.
