【摘要】　目的　 篩選人源喉癌Hep-2細胞株特異結(jié)合的短肽，作為喉癌靶向治療的載體。　方法　 體外培養(yǎng)Hep-2細胞株作為靶細胞，人正常喉黏膜上皮細胞為吸附細胞；用噬菌體展示十二肽庫進行3輪差減篩選，隨機挑取10個噬菌體克隆進行測序；采用酶聯(lián)免疫吸附（enzyme linked immunosorbent assay，ELISA）法鑒定噬菌體與Hep-2細胞的結(jié)合活性；通過免疫熒光鑒定喉癌細胞特異性結(jié)合肽（F2）噬菌體陽性克隆與喉癌細胞結(jié)合的特異性。　結(jié)果　 經(jīng)過3輪篩選后，噬菌體在靶細胞Hep-2上出現(xiàn)明顯富集；ELISA分析鑒定顯示5個陽性克隆能與Hep-2細胞特異結(jié)合，其中F2噬菌體克隆對喉癌細胞的結(jié)合靶向性明顯高于對照細胞（P lt;0.05）； 免疫熒光顯色顯示，F(xiàn)2能特異性地與喉癌細胞結(jié)合。　結(jié)論　 利用噬菌體展示肽庫技術(shù)，可以成功篩選到F2，其可能成為喉癌靶向治療的載體。
【Abstract】　Objective　 To obtain the polypeptides specifically bound to laryngeal squamous cell carcinoma line (Hep-2) and use it as a potential therapeutic vector targeting laryngeal squamous cell carcinoma patients.　Methods　 With the Hep-2 cells as the target cells and human normal laryngeal squamous epithelial cells (HNLE cells) as the absorber cells, 3 rounds of panning from a Ph.D.-12TM phage-display peptide library were carried out. Ten randomly selected phage clones were sent for sequence detection. The affinity of phage clones was detected by enzyme-linked immunosorbent assay (ELISA). The positive phage clones (F2) specifically bound to Hep-2 were identified by immunofluorescence detection.　Results　 After 3 rounds of screening, 5 positive phage clones showed specific binding to Hep-2 cells and the affinity of positive phage clones (F2) was significantly higher than that of the control groups (P lt;0.05). The results of immunofluorescence detection indicated that F2 could be specifically bound to Hep-2.　Conclusions　 Phage display peptide libraries technique can successfully screen the peptide specifically bound to Hep-2 cell line. Thus, it provides a potential vector for targeting therapy of laryngeal squamous cell carcinoma patients.
