Mechanistic consideration of the effect of perioperative volatile anesthetics on phagocytes

Koichi Yuki et al. Clin Immunol. 2021 Jan.

Abstract

A growing literature has shown that volatile anesthetics are promiscuous molecules targeting multiple molecules, some of which are critical for immunological functions. We focused on studies that delineated target molecules of volatile anesthetics on immune cells and summarized the effects of volatile anesthetics on immune functions. We also presented the perspectives of studying volatile anesthetics-mediated immunomodulation.

Keywords: Immunomodulation; Surgery; Volatile anesthetics.

Figure 1.. Signaling cascade for neutrophil recruitment and the effect of volatile anesthetics
(A) Lipid-chemokine interaction. LTB4 is released from injured tissues (left) and attracts neutrophils. Neutrophils recruited to the tissues release chemokines, which further attract neutrophils in the blood vessel (right). (B) Signaling cascades activated by chemoattractants and the effect of volatile anesthetics.

Mac-1, TLR2 and TLR4 activation induces gene expression of cytokines and chemokines such as tumor necrosis factor (TNF)-α, IL1-β, IL-6, IL-12 and IFN-β.
