Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will assess the amount and characteristics of regulatory T cells in peripheral blood, lymph nodes and different brain areas of stroke patients and compare these with patients without stroke. | — |
Secondary
| Measure | Time frame |
|---|---|
| To determine the immune temporal cellular landscape of the immune system in patients with acute stroke in the brain multiple study parameters are assessed (we will integrate results from brain histopathology, flow cytometric characterization of T cell subsets, CITE-seq, and spatial single-cell RNA sequencing (spatial scRNA-seq) analyses). | — |
