Exploring Core Genes Associated with Sepsis and Systemic Inflammatory Response Syndrome Using Single-Cell Sequencing...

Area of Science:

• Critical care medicine
• Immunology
• Genomics

Background:

• Sepsis and Systemic Inflammatory Response Syndrome (SIRS) are rising health concerns.
• Timely diagnosis and recognition of sepsis and SIRS remain challenging due to a lack of specific indicators.

Purpose of the Study:

• To identify unique markers and immune response patterns in sepsis and SIRS.
• To develop a novel approach for early diagnosis, treatment, and differentiation of sepsis and SIRS.

Main Methods:

• Single-cell RNA sequencing (scRNA-seq) was employed to analyze transcriptome data.
• UMAP cell clustering was used to analyze twelve cell clusters across four major blood cell types.

Main Results:

• Differences in major cell populations between sepsis death and SIRS patients were elucidated.
• Cellular components, marker genes, and immune response mechanisms were identified in both disease states.
• A theoretical framework for cellular and molecular regulation was established.

Conclusions:

• The study provides novel insights into the cellular and molecular mechanisms of sepsis and SIRS.
• The findings support an improved theoretical framework for early diagnosis and treatment strategies.
• This research facilitates better differentiation and prevention of sepsis and SIRS.
