Description
Sepsis is a leading cause of morbidity worldwide, driven by a dynamic response that evolves from early hyperinflammation to profound immunosuppression. This review explores the pathogenesis of the cytokine storm, detailing how dysregulated pattern recognition receptor (PRR) activation, NF-¿B signaling, and NETosis drive endothelial injury and organ dysfunction. Further, the transition into sepsis-induced immunoparalysis will be examined, characterized by lymphocyte apoptosis, “exhausted” cellular phenotypes, and persistent lymphopenia. This immune environment often results in Persistent Inflammation, Immunosuppression, and Catabolism Syndrome (PICS). Synthesis of clinical biomarkers and emerging therapies, such as immune checkpoint inhibition, will highlight the necessity of biomarker-guided, personalized strategies to navigate the sepsis continuum, seeking to alleviate hyperinflammation without advancing terminal immune failure.
