Antimicrobial peptides (AMPs) are essential components of the innate immune system, exhibiting diverse mechanisms of action. This study investigates the roles of cathelicidin (LL-37), alpha-defensins, and the S100 proteins S100A8 and S100A9 in systemic inflammation associated with sepsis, severe COVID-19, and acute pancreatitis using whole-blood bulk RNA-sequencing data. Gene co-expression network analysis revealed that during septic shock and severe COVID-19, cathelicidin and alpha-defensins ac...
