Tryptophan metabolism to kynurenine is a potential novel contributor to hypotension in human sepsis*

Abstract

: Indoleamine 2,3-dioxygenase 1 is expressed in resistance vessels in human sepsis and Indoleamine 2,3-dioxygenase activity correlates with hypotension in human septic shock. Indoleamine 2,3-dioxygenase 1 is thus a potential novel contributor to hypotension in sepsis.
