Most of the p50 JR did not co-localize with macrophages; coexistence of p65 and macrophage JR was seen occasionally.(2)In 20-30% of regenerating fibers, there were diffuse p50 and p65 JR. (3) No increase of NP- K B or AP-l JR was observed in neurogenic disorders. (4) For AP-1 IR, c-jun was increasd in a subset of regenerating fibers but not in necrotic fibers. JR of c-fos was not detected in all biopsies. Our results demonstrate that NF- K B and c-jun can be increascd in human muscle disease. Different distribu ion of NF- K B and AP-1 subunits points to their selective role in muscle patholoy.我們使用光學顯微鏡免疫組織化學的方法來觀察轉錄因子NF-κB及AP-1在正常肌肉及各種神經肌肉疾病的分佈情形。所使用的抗體包括NF-κB次單位PSO 、P65 的抗體與AP-l 次單位c-Jun 及c-Fos 的抗體。大部分的壞死細胞具有廣泛且強烈的p50 免疫活性。只有一部分的壞死細胞具有p65 的免疫活性。這些免疫活性並非存在於巨噬細胞內。在20 -30 ％的再生細胞中可觀察到P65 及p50 的免疫活性。AP-1中的c-Jun 免疫活性在一部分的再生細胞中有增加的現象，不過在壞死細胞中並不增加。C-fos 的免疫活性並沒有觀察到有明顯的變化。在神經源性疾病不管AP-l 或NF-κB均無明顯變化。AP-l 或NF-κB在肌肉的壞死及再生可能扮演著一重要的角色。不同的次單元也具有不同的地位。application/pdf276647 bytesapplication/pdfzh-TW國立臺灣大學醫學院神經科transcription factorNF-κBAP- 1immunocytochemistryneuromuscular disease轉錄因子AP-l免疫組織化學神經肌肉疾病[SDGs]SDG3journal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/26075/1/882314B002292.pdf
