摘　　要：应用RT-PCR方法,分别检测了CCL28在15 d和30 d龄仔猪胃肠道组织中的表达。结果表明,CCL28在15 d龄猪的十二指肠、回肠、盲肠、结肠、直肠和30 d龄仔猪的十二指肠上段、下段、空肠、回肠、盲肠、结肠、直肠、胃组织中有表达;在15 d龄仔猪的十二指肠上段、空肠、胃组织中无表达,在回肠、结肠组织中表达弱;在30 d龄仔猪的十二指肠、空肠、盲肠、胃组织中表达弱。CCL28的时空表达提示其与仔猪胃肠道黏膜组织的发育及在不同部位的作用有关。The expressions of CCL28 in the gastrointestinal tract of 15 - day - old and 30 - day - old piglets were determined by using RT -PCR method. The results showed that CCL28 mRNA was expressed in duodenum, ileum, cecum, colon, rectum of 15 -day - old piglet and in duodenum, jejunum, ileum, cecum, colon, rectum and stomach tissues of 30 -day -old piglet; no expression in duodenum, jejunum and stomach tissues, a little in ileum, colon tissues of 15 -day -old piglet and in duodenum, jejunum, cecum, stomach tissues of 30 - day - old piglet. The time - space expression of CCI-28 showed that it was related to the gastrointestinal mucosal immune system development in the piglets and roles in different tissues.
