Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Senescent CD8 T cells (either determined by CD28 negativity or CD57 positivity) as modifying factor Response to treatment will be analysed via HDRS-17 score improvement. | — |
Secondary
| Measure | Time frame |
|---|---|
| Other immune senescence markers 1. Number of *senescent* CD4+ T cells in the effector memory (EM) and effector memory re-expressing CD45RA (EMRA) populations 2. Signs of monocyte senescence: Monocyte gene expression of mitochondrial apoptosis (BAX, BCL10, EGR1, EGR2) and the SASP related gene TNF 3. Signs of the monocyte inflammatory pyroptosis state: Monocyte gene expression of the inflammatory genes IL- 1A, IL-1B, IL-6, CCL20 and TNFAIP3 4. Correlates of the monocyte senescent and inflammatory state in whole blood material TEMPUS): The gene expression of amongst others BAX, SERPINE1, TGFBR3, NFATC2, TNFAIP3, FOXP3 and CD8 5. Levels of the T cell senescence related growth serum factor IL-7 6. High or low levels of the inflammaging serum factors hsCRP and IL-6 | — |
