Intradermal lipopolysaccharide challenge as an acute in vivo inflammatory model in healthy volunteers.

Br J Clin Pharmacol 2021 Jul 22. Epub 2021 Jul 22.

Centre for Human Drug Research, Leiden, the Netherlands.

Introduction: Whereas intravenous administration of TLR4 ligand lipopolysaccharide (LPS) to human volunteers is frequently used in clinical pharmacology studies, systemic use of LPS has practical limitations. We aimed to characterize the intradermal LPS response in healthy volunteers, and as such qualify the method as local inflammation model for clinical pharmacology studies.

Methods: 18 healthy male volunteers received two or four intradermal 10 ng LPS injections and one saline injection on the forearms. Read More

Presence of Donor Lymph Nodes Within Vascularized Composite Allotransplantation Ameliorates VEGF-C-mediated Lymphangiogenesis and Delays the Onset of Acute Rejection.

Transplantation 2021 Aug;105(8):1747-1759

Department for BioMedical Research, University of Bern, Bern, Switzerland.
