| I. Background | |
| HHLA2（也稱為 B7H5、B7H7 或 B7y）是 B7 家族的一員，它是 I 型跨膜蛋白，由具 有串聯 IgV1-IgC-IgV2 結構域的細胞外部分、跨膜區域和細胞質尾部組成。HHLA2 低表達 于胎盤、腸道上皮細胞等，高表達于多種實體瘤（如肺癌、乳腺癌、結直腸癌、腎癌）及 炎癥微環境。HHLA2 具有雙向免疫調節功能：結合抑制性受體 KIR3DL3（NK 細胞）和未 知 T 細胞受體，傳遞抑制信號，減弱抗腫瘤免疫應答；通過受體 TMIGD2 激活 PI3K-AKT 通路，促進 T 細胞存活及記憶形成。 | |
| II. Description | |
HHLA2(B7H7) aAPC Cell 作 為 KIR3DL3 Effector Reporter Cell 或 TMIGD2 Effector Reporter Cell 的 靶 細 胞 ， 很好的模擬了體內 KIR3DL3/ HHLA2(B7H7) 或TMIGD2/HHLA2(B7H7)的信號轉導過程，原理見下圖所示。  Figure 1. HHLA2(B7H7) aAPC Cell 細胞模型原理圖 | |
