본 연구에서는 호랑나비 유충의 유전체 분석을 통해 선별된 파필리오신 3의 항균 및 항염증 활성을 확인하였다. 선행연구에서 RNA 시퀀싱 분석을 통해 호랑나비의 전사체를 분석하였으며, 결과를 바탕으로 인실리코(in silico)분석을 진행하여 전사체 유래 항균 펩타이드를 스크리닝하고 선발하였다. 수행된 항균 활성 및 용혈 활성 테스트에서 파필리오신 3은 그람음성균인 E. coli와 그람양성균인 S. aureus에 대해 강력한 항균활성을 나타낸 반면 마우스 적혈구에 대한 용혈 활성은 전혀 없었다. 다음으로 마우스 대식세포주 Raw264.7 세포를 이용하여 파필리오신 3의 항염증 활성을 확인하였다. 그 결과 파필리오신 3은 LPS로부터 유도된 Raw264.7 세포들의 산화질소 생성을 감소시키는 결과를 보여주었다. 뿐만 아니라 실시간 역전사 중합효소 연쇄반응(qRT-PCR) 방법과 효소결합 면역흡착측정법(ELISA)을 통해 파필리오신 3이 Raw264.7 세포에서 전염증성 사이토카인(IL-6, IL-1β)의 발현을 감소시킨다는 것을 확인할 수 있었다. 또한, 염증반응의 신호전달인자들(MAPKs, NF-κB)의 인산화를 억제하는것을 확인하였는데, 이는 파필리오신 3이 LPS와의 상호작용을 통해 결합하여 효과를 나타낸다는 것을 확인할 수 있었다. 이러한 결과들은 호랑나비 유전체 분석을 통해 확인된 파필리오신 3이 새로운 항균 및 항염증 치료제로서 개발하는데 가능성 있는 물질로 사료된다.

The development of novel peptide antibiotics with potent antimicrobial activity and anti-inflammatory activity is urgently needed. In a previous work, we performed an in-silico analysis of the Papilio xuthus transcriptome to identify putative antimicrobial peptides and identified several candidates. In this study, we investigated the antibacterial and anti-inflammatory activities of papiliocin 3, which was selected bioinformatically based on its physicochemical properties against bacteria and mouse macrophage Raw264.7 cells. Papiliocin 3 showed antibacterial activities against E. coli and S. aureus without inducing hemolysis and decreased the nitric oxide production of the lipopolysaccharide-induced Raw264.7 cells. Moreover, ELISA and Western blot analysis revealed that papiliocin 3 reduced the expression levels of pro-inflammatory enzymes, such as inducible nitric oxide synthase (iNOS), cyclooxygenase- 2 (COX-2), and prostaglandin E2 (PGE2). In addition, we examined whether papiliocin 3 could inhibit the expression of pro-inflammatory cytokines (interleukin-6 and interleukin-1β) in LPSinduced Raw264.7 cells. We found that papiliocin 3 markedly reduced the expression level of cytokines through the regulation of mitogen-activated protein kinases (MAPK) and nuclear factor kappa B (NF-κB) signaling. We also confirmed that papiliocin 3 binds to bacterial cell membranes via a specific interaction with lipopolysaccharides. Collectively, these findings suggest that papiliocin 3 could be a promising molecule for development as a novel peptide antibiotic.
