Patients and clinical data
This study included four TA patients admitted to our hospital from 2019.10 to 2020.5. We collected peripheral blood samples from the patients. All samples were used for scRNA-seq. In addition, peripheral blood from four age-sex matched healthy individuals was collected as control for scRNA-seq. All the contents of this study meet the relevant requirements of the ethics committee. Written consent was obtained from the patients/healthy individuals or their families
The basic clinical data obtained from TA patients are described inTable S1 . The four female patients were aged between 16 – 39 years, which is in line with the age and gender prevalence of TA. Although the C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) of the patients were within the normal range, the history of taking glucocorticoids (methylprednisolone or prednisone acetate) and other drugs (methotrexate) prevented these patients from being rated on NIH scores.
