The 3-Acetylpyridine(3-AP) induces cerebellar injury which is chemoablation of the inferior olive nucleus. The purpose of this study was to investigate the effects of exercise(Ex) and electroacupuncture(EA) on muscle activity of hindlimb and serum brain derived neurotrophic factor(BDNF) in the ataxi...

3-Acetylpyridine는 어떤 물질인가? | 3-Acetylpyridine(3-AP)는 아래올리브핵을 선택적으로 파괴함으로써, 소뇌 손상을 유발하는 신경독소이다. 본 연구에서는 3-AP의 투여로 운동실조가 유발된 동물모델에서 로타로드 운동과 전침이 후지의 근활성도와 혈청 BDNF에 미치는 영향을 알아보고자 하였다. | |
소뇌는 어떤 역할을 담당하는가? | 소뇌는 대부분의 신체 영역으로부터 수입성 정보를 받아들여 척수, 교뇌, 중뇌, 시상 및 대뇌피질과 회로를 형성하고, 평형과 근긴장도 유지를 위한 협조 작용을 담당한다[1]. 이와 같은 소뇌의 해부학적 및 생리학적 특징으로 인해 소뇌에 대해 직접적인 손상이 가해지지 않더라도 소뇌성 증후들이 나타날 수 있다[2][3]. | |
신경영양인자 중 BDNF의 특징을 무엇인가? | 대표적인 것으로, 뇌유래신경영양인자(brain-derived neurotrophic factor, BDNF), 신경성장인자(nerve growth factor, NGF), 신경영양인자-3(neurotrophin-3, NT-3), 신경영양인자-4/5 (neurotrophin-4/5, NT-4/5) 등이 있다[15]. BDNF는 해마와 신피질을 포함하여 뇌의 여러 부분에서 발현되며, 신경변성과 국소빈혈에 의한 신경세포의 퇴행에 대하여 보호기능을 한다[16][17]. 많은 연구에서 내인적으로 또는 외인적으로 공급되는 BDNF와 같은 신경영양인자들이 병변부위의 운동신경원 고사를 줄이고, 말초신경 재생을 촉진시키는 것으로 보고되고 있다[18][19]. |
