Exosomal delivery of IL-10: Biodistribution, pharmacokinetics, and preterm birth prevention strategies

This study investigates the potential of extracellular vesicles (EVs) loaded with interleukin-10 (IL-10) to reduce infection-induced preterm birth (PTB). IL-10 has shown promise in reducing PTB by dampening inflammatory responses, but challenges exist with intraamniotic administration. The study eva...

description This study investigates the potential of extracellular vesicles (EVs) loaded with interleukin-10 (IL-10) to reduce infection-induced preterm birth (PTB). IL-10 has shown promise in reducing PTB by dampening inflammatory responses, but challenges exist with intraamniotic administration. The study evaluates IL-10 gene-transfected cell-produced EVs containing IL-10 (tIL-10), comparing them with recombinant IL-10 (rIL-10) and rIL-10 incorporated in EVs via electroporation (eIL-10). Characterization of tIL-10 includes size, shape, and molecular markers. Functional assays demonstrate tIL-10's ability to reduce pro-inflammatory cytokine production and extend half-life, with biodistribution in maternal and fetal tissues. The study findings indicate that tIL-10 displays an average size of 108.7 ± 20.5 nm, round with a diameter of ∼0.12 μm, and expresses EV markers CD9 and CD81, containing IL-10 cargo. In vitro, LPS stimulation demonstrates that tIL-10 significantly reduces the production of pro-inflammatory cytokines IL-6 and IL-8 from maternal decidual cells. Biodistribution studies reveal tIL-10 presence in placental and fetal membranes within 5 min, persisting for up to 3 h. Pharmacokinetic studies using non-compartmental analysis of plasma data, and the linear trapezoidal method establish key pharmacologic parameters for each drug. Pharmacological findings establish eIL-10 and tIL-10's ability to significantly delay PTB onset after E. coli exposure. These findings underscore the potential of tIL-10 as an effective therapeutic agent for PTB, with implications for clinical practice and further research in reproductive pharmacology.
