해조류 유래 다당류와 장 건강

국문 초록 (Abstract)

전 세계적으로 염증성 장질환의 발병률이 지속적인 증가추세를 보이는 가운데, 그 원인과 기전에 대한 적극적인 연구가 진행되고 있음에도 불구하고 아직 뚜렷한 치료제의 개발은 미비한 실정이다. 염증성 장질환의 원인에는 유전적, 후생유전적, 환경적 요인 외에도 숙주의 면역상태 등이 복합적으로 영향을 미치는 것으로 보고되어 있으며 특히 환경적인 요인 중 식이는 장 건강에 큰 영향을 미친다. 인간의 소화 작용에 의해 분해되지 않고 장까지 도달하는 난소화성 식이 섬유소는 장내 미생물의 먹이로 사용되고 선택적으로 바람직한 장내 미생물인 프로바이오틱스(probiotics)의 성장에 영향을 주는 프리바이오틱스(prebiotics)의 기능을 수행함으로써 장 건강에 긍정적인 영향을 준다고 알려져 있다. 최근 풍부한 식이 섬유소롤 함유하고 있는 해조류 유래 다당류의 프리바이오틱스로의 기능이 대두되면서 장 건강 증진을 위한 기능성 물질로써의 역할과 그 기전 연구가 활발히 진행되고 있다. 본 총설에서는 해조류 유래 다당류, 주로 후코이단과 라미나린 등이 장 건강과 장내 미생물의 성장에 미치는 영향 및 염증성 장질환의 재발과 치료를 위한 잠재적인 기능성 원료로써 가능성을 in vitro와 in vivo 실험 결과를 바탕으로 논의해 보도록 하겠다.

다국어 초록 (Multilingual Abstract)

The incidence of inflammatory bowel disease(IBD) has increased continuously in worldwide, but no cure have been discovered. The etiology of IBD may include various factors such as genetics, epigenetic, environment as well as host immune system. Among the environmental factors of IBD, diet heavily influences gut health, especially non-digestible dietary fiber can have a great impact on selective growth of beneficial gut microbiota called probiotics. Seaweeds have been consumed in Asia countries and are a rich source for dietary fiber. Accumulated data have suggested the possibility of utilizing seaweed derived oligosaccharides as prebiotics to prevent IBD and its recurrence. In this review, seaweed derived oligosaccharides such as fucoidan and laminarin regarding gut health and potential therapeutic tools for IBD will be discussed based on studies conducted in vitro and in vivo models.
