Project description:RNA was extracted from whole blood of subjects collected in Tempus tubes prior to COVID-19 mRNA booster vaccination. D01 and D21 correspond to samples collected at pre-dose 1 and pre-dose 2 respectively. RNA was also extracted from blood collected at indicated time points post-vaccination. DB1, DB2, DB4 and DB7 correspond to booster day 1 (pre-booster), booster day 2, booster day 4 and booster day 7 respectively. The case subject experienced cardiac complication following mRNA booster vaccination. We performed gene expression analysis of case versus controls over time.

Single-cell insights into immune dysregulation in rheumatoid arthritis flare versus drug-free remission

Project description:Immune-mediated inflammatory diseases (IMIDs) are typically characterised by relapsing and remitting flares of inflammation. However, the unpredictability of disease flares impedes their study. Addressing this critical knowledge gap, we used the experimental medicine approach of immunomodulatory drug withdrawal in rheumatoid arthritis (RA) remission to synchronise flare processes, allowing characterisation with unprecedented detail. We used single cell RNA sequencing to analyse the diversity and comparative longitudinal changes in paired circulating lymphocyte samples from 12 patients with RA in remission prior to drug cessation (on-drug remission) and after drug cessation (either off drug flare, or drug-free remission) as part of the Biomarkers of Remission in Rheumatoid Arthritis (BioRRA) Study.
