당뇨병이 발생하는 기전은 무엇인가? | 당뇨에 대한 병태·생화학적 기전들을 보면 인체 내 항산화 방어기전이 손상되어 활성산소(free radical)의 생성을 높여 세포 내 단백질과 세포막 지질의 변형, 공간 배열의 손상, 조직내 미토콘드리아 DNA (mtDNA)의 손상[2,7]과 고혈당증(hyperglycemia)으로 생성된 반응성 산소종(reactive oxygen species)인한 저밀도 지단백(low-density lipoprotein)의 지질과산화 증가[18,40] 등이 있다. | |
GLUT-1은 무엇인가? | 뇌의 중추신경계에 필요한 주 에너지원인 글루코스를 말초 혈액에서 뇌까지 공급하고 이동시키는데 관여하는 단백질인 GLUT-1 (glucose transporter-1)은 글루코스가 뇌혈관장벽(blood-brain barrier)의 내피세포를 지나가도록 도와주기 때문에 혈당조절에 중요한 인자[12]로써 활동을 하며, 뇌의 피질 부분과 시상 및 해마를 포함한 거의 모든 신경세포체에서 광범위하게 분포되어 뇌의 기억력활동을 조절해 준다[32]. 그러나 당뇨병 환자들의 뇌에서는 GLUT-1의 발현이 억제 되는 것으로 알려져 있기 때문[11]에 GLUT-1 단백질을 활성화시키는 방안이 시급하다. | |
당뇨병이란 무엇인가? | 당뇨병은 고혈당, 인슐린 분비 부족 및 결핍과 인슐린 수용체의 민감도 저하 등의 원인으로 생기는 질환이며, 장기간 지속되면 합병증이 나타나며, 대표적인 합병증은 당뇨성 망막증(retinopathy), 신장병(nephropathy), 신경병증(neuropathy)등을 유발한다[2,7]. |
