“…Inflammation caused by peptidoglycan from P. acnes cell wall in AV lesion may activate the TLR-2 receptors in mononuclear and polymorphonuclear cells in the vicinity of the sebaceous follicle. The bond between TLR-2 and peptidoglycan will induce the production of pro-inflammatory cytokines such as IL-1, IL-8, IL-12, and TNF-α [1][2][3]. Soy isoflavoneshas anti-inflammatory effect, thus may be considered for future AV treatment, especially as the substitute for isotretinoin (13-cis retinoic acid; 13-cis RA), a systemic retinoid effective for severe acne treatment and, currently, the only drug that can induce permanent long term AV remission [1,2].…”
