dc.description.abstract | Purpose STAT1 gain-of-function (GOF) and dominant-negative (DN) STAT3 syndromes share clinical manifestations includ ing infectious and infammatory manifestations. Targeted treatment with Janus-kinase (JAK) inhibitors shows promising
results in treating STAT1 GOF-associated symptoms while management of DN STAT3 patients has been largely supportive.
We here assessed the impact of ruxolitinib on the JAK-STAT1/3 pathway in DN STAT3 patients’ cells.
Methods Using fow cytometry, immunoblot, qPCR, and ELISA techniques, we examined the levels of basal STAT1 and
phosphorylated STAT1 (pSTAT1) of cells obtained from DN STAT3, STAT1 GOF patients, and healthy donors following
stimulation with type I/II interferons (IFNs) or interleukin (IL)-6. We also describe the impact of ruxolitinib on cytokine induced STAT1 signaling in these patients.
Results DN STAT3 and STAT1 GOF resulted in a similar phenotype characterized by increased STAT1 and pSTAT1 levels
in response to IFNα (CD3+ cells) and IFNγ (CD14+ monocytes). STAT1-downstream gene expression and C-X-C motif
chemokine 10 secretion were higher in most DN STAT3 patients upon stimulation compared to healthy controls. Ex vivo
treatment with the JAK1/2-inhibitor ruxolitinib reduced cytokine responsiveness and normalized STAT1 phosphorylation in
DN STAT3 and STAT1 GOF patient’ cells. In addition, ex vivo treatment was efective in modulating STAT1 downstream
signaling in DN STAT3 patients.
Conclusion In the absence of efective targeted treatment options for AD-HIES at present, modulation of the JAK/STAT1
pathway with JAK inhibitors may be further explored particularly in those AD-HIES patients with autoimmune and/or
autoinfammatory manifestations. | es |
