Emerging studies revealed that numerous plant-or fungal-derived extracts significantly modulate immune responses. Antroquinonol (Antro), a characteristic triterpenoid compound isolated from Antrodia camphorata, has been extensively documented for its anti-inflammatory properties, but the precise mechanisms remain unclear. In this study, we established a macrophage polarization model in vitro to evaluate the impact of Antro on macrophage polarization. Our findings demonstrate that Antro enhances the enzymatic activities of DNA methyltransferases and facilitates DNA methylation-mediated suppression of Tlr4 expression, thereby inhibiting NF-κB signaling, ultimately attenuating IL-1β production in macrophages. Our study elucidates the anti-inflammatory effects of Antro, which significantly enriches the theoretical framework of natural product-mediated immunomodulation (particularly plant/fungal extracts). These findings provide critical scientific support for developing A. camphorata-derived products as novel food or feed additives to elevate immune function.
