Abstract
Protaetia brevitarsis seulensis larva is well-known as an edible insect. The present study aimed to explore the immune-enhancing effect of 30% ethanol extract of Protaetia brevitarsis seulensis larvae (PBE) in RAW264.7 macrophage cells. PBE were not cytotoxic to RAW264.7 cells and nitric oxide production increased on PBE treatment in a dose-dependent manner. Furthermore, PBE significantly promoted the expression of immune-related mediators (iNOS and COX-2) and cytokines (TNF-α, IL-6, and IL-1β) and the phosphorylation of MAPKs (ERK, p38, and JNK). Taken together, the immune-enhancing effects of 30% ethanol extract of PBE in vitro were identified. These findings can be used as data for the development of edible insect-based functional foods that improve immune function.
