To define how physiologically relevant inflammatory signals, such as cytokines and chemokines, remodel neutrophil chromatin accessibility in whole blood and to assess the correlation of these changes with clinically relevant transcriptional states in sepsis.
Approach:
Key Findings:
NF stimulation induced distinct chromatin accessibility programs compared to PMA, suggesting different regulatory pathways.
Specific transcription factor motifs were enriched based on the type of NF used, indicating tailored responses.
Changes in promoter accessibility under NF stimulation correlated with transcriptional states associated with sepsis severity, emphasizing the clinical relevance.
Interpretation:
The study demonstrates that NF stimulation in whole blood reveals chromatin accessibility changes in neutrophils that are linked to disease severity in sepsis, potentially guiding therapeutic strategies.
Limitations:
The study primarily focuses on specific NFs and may not encompass all physiological stimuli affecting neutrophil function, such as other cytokines or environmental factors.
The findings may not fully represent neutrophil behavior in all clinical contexts due to the complexity of in vivo environments, which can vary significantly.
Conclusion:
The findings provide a framework for linking cytokine-driven neutrophil regulation to inflammatory states in sepsis and other NET-associated diseases, with implications for targeted therapies.
