| Measure | Time frame |
|---|---|
| Comparison of the degree of T cell activation by anti-CD3/CD28 antibodies before and after stimulation. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. comparison with previous reports in patients with diseases related to the activation state of immune cells (rheumatoid arthritis, inflammatory bowel syndrome, knee osteoarthritis, interstitial pneumonia, epilepsy) 2. comparison with samples from patients with diseases regarding the expression positivity and intensity of a group of molecules whose expression is induced by low-frequency stimulation 3. comparison with previous reports on disease-related gene variants in patients with disease 4. correlation between brain activity data in MRI and expression of various analysed molecules | — |
