Research on the role and mechanism of Aloe vera (L.) Burm.f. in the treatment of burn: Based on network pharmacology analysis and experimental verification

Burn is a suddenly occurring injury. The healing process of burn is complex. Aloe vera (L.) Burm.f. (Av) is widely used as Chinese folk medicine for the treatment of burn. While effective pharmacological components, role and mechanism of Av in the treatment of burn remain to be fully elucidated. Arachidonic Acid (AA) and Quercetin (QUE) are identified as active components of Av for the treatment of burn by network pharmacology analysis and experimental verification. Animal experiments’ results showed that AA and QUE could shorten the burn wound healing time. The expression of inflammatory factor TNF-α, MyD88 and P-NF-κB p65 were down-regulated and the ER (ESR1), SRC were up-regulated in AA treated NIH 3T3 cells. The expression of MyD88 was downregulated in QUE treated NIH 3T3 cells. The Av promotes burn healing may be via the anti-inflammatory effect and regulation on NF-κB signal pathway or estrogen signal pathway by its active components AA and QUE. This research may construct a bridge between Av and burn wounds, and skin therapy agent exploration.
