Treatment protocol |
As published previously (Lauruschkat et al., 2021, J Fungi), 2.7-mL blood collection tubes without anticoagulant were pre-loaded with co-stimulatory antibodies α-CD28 and α-CD49d (10 µg/mL, Miltenyi Biotec, Bergisch Gladbach, Germany) plus either no antigen (negative control) or SARS-CoV-2 spike peptides (Prot_S, 0.6 nmol per peptide/mL, Miltenyi Biotec, Bergisch Gladbach, Germany). 0.5 mL blood lithium-heparin blood was added and stimulation tubes were incubated for 20 – 24 h at 37 °C. Samples were transferred to 1.5 mL tubes and centrifuged at 2000 g for 20 min. After preservation of the supernatant for LegendPlex cytokine assays, the residual cell pellet underwent erythrocyte lysis using Buffer EL (Qiagen, Hilden, Germany) and was then cryopreserved in 1 mL RNAprotect buffer (Qiagen, Hilden, Germany).

Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was isolated using the RNeasy Plus Mini Kit according to the manufacturer's instructions (Qiagen, Hilden, Germany).
|
Label |
n/a
|
Label protocol |
Hybridisation with labelled probes was performed according to the manufacturer's instructions (Nanostring, Seattle, USA): RNA concentration was normalized to 50 ng in 5 µL water. The lyophilyzed Reporter Code set was reconstitued using 70 µL Hybridisation Buffer. 50 ng of RNA was mixed with 8 µL of Reporter Codeset solution and 2 µL of (ready-to-use) Capture Probe Set.
|
|
|
Hybridization protocol |
Hybridisation was performed for 16-24 h at 65 °C.
|
Scan protocol |
17 µL water was added to the hybridized samples. 30 µL of each sample was loaded onto a Nanostring nCounter Sprint Cartridge and analyzed using an nCounter Sprinter device (Nanostring, Seattle, USA).

Description |
nCounter Immune Exhaustion Panel Reporter CodeSet
|
Data processing |
Data was analyzed using the nSolver Analysis Software (Nanostring, Seattle, USA), with background thresholding to the median of negative controls and normalization to the panel’s 12 internal reference genes (geometric mean). mRNA counts normalized to internal reference genes by the nSolver Analysis Software (Nanostring, Seattle, USA).
