Ferroptosis mediated by the IDO1/Kyn/AhR pathway triggers acute thymic involution in sepsis.

Acute thymic involution (ATI) is frequently observed during sepsis, however the underlying mechanisms remain poorly understood. This study demonstrates that ferroptosis plays a crucial role in sepsis-associated ATI. We found that pediatric sepsis patients showed significantly elevated kynurenine (Kyn)/tryptophan (Trp) ratios, indicating increased indoleamine 2,3-dioxygenase 1 (IDO1) activity, along with higher Kyn levels compared to controls.

Untargeted lipidomics profiling provides novel insights into pediatric patients with sepsis: an exploratory study.

Sialic acid-modified nanomedicines modulate neutrophils for dual therapy of cancer and sepsis: addressing neglected sepsis comorbidities during cancer treatment.

Advanced cancer patients face a high risk of sepsis due to immune suppression and infection susceptibility. To tackle this challenge, we developed an innovative animal model that simulates the clinical scenario of late-stage cancer complicated by sepsis and designed a sialic acid (SA)-modified paclitaxel (PTX) liposome (PTX-SAL). This formulation specifically targets overactivated peripheral blood neutrophils (PBNs) by binding to L-selectin on their surface.
