溃疡性结肠炎 (ＵＣ)是一种结肠慢性炎症伴随自身免疫过程的疾病。以前曾报道了ＵＣ患者结肠粘膜的组织特异性ＩｇＧ抗体的表达并鉴定出一种 4 0 0 0 0 0Ｄ的结肠蛋白Ｐ4 0 ,它能与ＵＣ结肠粘膜的ＩｇＧ反应。克隆氏病 (ＣＤ)结肠中的结肠组织特异性ＩｇＧ不识别Ｐ4 0 ,说明Ｕ
Ulcerative colitis (UC) is a disease of chronic inflammation of the colon with an autoimmune process. The expression of tissue-specific IgG antibodies to colonic mucosa in UC patients has previously been reported and a colloidal protein P4o of 20000DD has been identified that is capable of reacting with the IgG of UC colonic mucosa. Colon tissue-specific IgG in Crohn’s disease (CD) colon does not recognize P4o, indicating U.
