Abstract
Description
実施例1:
実験材料および方法
0.5μgのプラスミドDNAおよび2μlのリポソーム2000(Cat#11668-027、Invitrogen)を50μlの無血清培地に溶解し、一緒に混合し、室温で20分間放置し、次いで細胞ウェルにゆっくりと加え、細胞培養プレートを細胞インキュベーターに戻して24時間インキュベートした。2日目に、タンパク質発現は、100μlの酵素結合免疫吸着アッセイ(ELISA)によって検出された。
1、発現担体の構築
この研究によると、遺伝子組換えFc融合タンパク質SIRPαD1-Fcは、良好なターゲット結合活性を有し、その活性がSIRPα-Fcよりも顕著に優れた。グリコシル化部位(HY03M)の除去後、ターゲット活性はさらに改善された。体内研究によると、HY03Mタンパク質が強い抗腫瘍活性を有し、HL60モデルについて、腫瘍を完全に排除する効果を達成した。当該タンパク質の主な抗腫瘍メカニズムは、2つの側面を含む。一側面では、FcとFcγRsとの結合を阻害することによって、SIRPαにより伝達された抑制的シグナルを阻害して受動的にマクロファージを活性化した。他側面では、CD47とSIRPαとの結合によって、能動的にマクロファージを活性化した。これら2つのメカニズムは、互いに協力して、マクロファージによる腫瘍細胞への貪食を完全に活性化し、クロファージがさらに腫瘍抗原をTリンパ細胞(Tseng D,et al.,2013)に交差伝達して、最終的には腫瘍細胞を破壊した。
