- Abstract
- – Presbyopia is characterized by a loss of the accommodative ability of the eye that negatively affects vision-aided health-related quality of life. Local inflammation in the eye diminishes parasympathetic cholinergic stimulation and contraction of the iris and ciliary muscle in the eyes via the muscarinic (cholinergic) receptor. Along with the cholinergic agent, a non-steroidal anti-inflammatory agent is often integrated to ameliorate presbyopia. Chrysanthemum morifolium belongs to the Asteraceae. We examined whether Chrysanthemum morifolium flower extract (CME) has parasympathomimetic and anti-inflammatory activity in HLE-B3 human lens epithelial cells and RAW 264.7 macrophages. CME induced time-and dose-dependent production of IP1 and Ca2+ accumulation in HLE-B3 cells. In the LPS-induced inflammatory response, CME treatment downregulated inducible nitric oxide synthase (iNOS) and nitric oxide in RAW 264.7 macrophages. CME downregulated the levels of interleukin-1β (IL-1β) and interleukin-6 (IL-6) with no change in TNF-α levels. In addition, the phosphorylation of JNK and p38 was reduced with no change in ERK by CME in LPS-treated cells. These findings suggest that the parasympathetic and anti-inflammatory efficacy of CME can be applied to develop therapeutics against presbyopia. © 2024, Korean Society of Pharmacognosy.
