초록
Endotoxin은 장의 그람음성균의 리포다당체로서 혈중 endotoxin의 농도가 높아지면 인슐린 저항성과 비만 및 당뇨와 같은 대사성질환의 발병율이 높아지게 된다. 또한 endotoxin은 CD14 및 TLRs와 결합해 대식세포를 자극하고 TNF-α, IL-6 등과 같은 염증성 사이토카인 분비를 증가시키게 되고, 아울러 체내의 만성적 염증증가는 면역시스템의 붕괴를 가져오고 세균 및 항원에 반응하지 못하게 되어 내독소혈증과 같은 질환으로 이어지게 된다. 한편, 운동은 비만, 당뇨뿐 아니라 대부분의 대사성 질환에 효과가 있으며 운동중재를 통해 염증지표 개선 및 면역력 강화에 도움을 주는 것으로 알려져 있다. 따라서 꾸준한 운동습관 형성이 체내 endotoxin 농도 감소와 함께 대사성 질환을 예방하고 만성적 염증을 감소시키며 면역력을 강화하는데 도움을 줄 것으로 사료된다.
Abstract
Endotoxin is a gut lippolipopolysaccharide of Gram-negative bacteria. Endotoxin plasma concentration occurring at higher insulin resistance in metabolic disorders such as obesity and diabetes is the greater incidence. Endotoxin is also combined CD14 and TLRs and stimulates macrophages and TNF-α, IL-6, such as the secretion of inflammatory cytokines increases. In addition, chronic inflammation in the body increases the breakdown of the immune system in response to antigens bringing bacteria and prevent diseases such as endotoxemia will lead to. On the other hand exercise is well known that obesity, diabetes, as well as most of the effects on metabolic disease and inflammation, and improve indicators that help to strengthen the immune system through exercise interventions. Therefore suggest that regular exercise habit formation reduces plasma endotoxin concentrations decreased with metabolic disease prevention and help strengthen the immune system, reduces chronic inflammation is considered.
