ovalbumin and cirsilineol

Allergic rhinitis (AR) is a common type of inflammatory disease with symptoms including rhinorrhea, fatigue, sneezing, and disturbed sleep. AR affects nearly 40% of peoples worldwide with the increased numbers of new cases. In this work, the study was conducted to disclose the anti-inflammatory and antiallergic properties of cirsilineol against the ovalbumin (OVA)-sensitized AR in mice. AR was provoked in BALB/c mice through the OVA challenge 30 days along with 10 and 20 mg/kg of cirsilineol treatment. The nasal symptoms, i.e., rubbing and sneezing was monitored after the final OVA challenge. The status of OVA-specific IgE, PGD2, and LTC4 was investigated using assay kits. The status of pro-inflammatory markers also examined using assay kits. The levels of oxidative markers, SOD activity, and pro-inflammatory markers in the spleen mononuclear cells (SMEs) were studied by using respective assay kits. The mRNA expression of TXNIP was assessed using RT-PCR study. The 10 and 20 mg/kg of cirsilineol treatment effectively decreased the sneezing and nasal rubbings in OVA-provoked mice. Cirsilineol also decreased the IgE, PGD2, and LTC4 status in the AR animals. The status of pro-inflammatory markers, i.e., IL-4, IL-5, IL-6, IL-33 and TNF-α was found to be decreased in the cirsilineol administered AR mice. Cirsilineol effectively reduced the ROS and MDA and improved SOD in the OVA-challenged SMCs. The mRNA expression of TXNIP was appreciably suppressed by the cirsilineol treatment. Altogether, these findings proved the beneficial actions of cirsilineol against the OVA-triggered AR in mice. The additional studies on the cirsilineol could lead to the development of new drug for AR management.
