β-caryophyllene ameliorated obesity-associated airway hyperresponsiveness through some non-conventional targets.

Phytomedicine 2021 May 25;89:153610. Epub 2021 May 25.

Division of Pharmaceutical Technology, Defence Research Laboratory, Tezpur, 784001, India. Electronic address:

Background: Obesity worsens airway hyperresponsiveness (AHR) in asthmatic subjects by up-regulating macrophage polarization that leads to excessive secretion of pro-inflammatory adipokines from white adipose tissue followed by generation of oxidative stress in the respiratory system. Treatment through conventional signaling pathways proved to be inadequate in obese asthmatics, so a therapeutical approach through a non-conventional pathway may prove to be effective.

Purpose: This study aimed to investigate the efficacy of a FDA-approved food additive, β-caryophyllene (BCP) in obesity-associated AHR. Read More
