PDPN

PDPN全稱為平足蛋白(Podoplanin),又名Aggrus、T1-alpha,是一種跨膜糖蛋白。PDPN通過與血小板C型凝集素樣受體CLEC-2結合,在腫瘤微環(huán)境中誘導血小板活化,促進癌細胞轉移和血管生成。其在膠質母細胞瘤、肺癌及頭頸部鱗癌中高表達,通過激活PI3K/Akt通路增強腫瘤細胞侵襲性,同時參與調控淋巴管發(fā)育異常相關的疾病。臨床數(shù)據(jù)顯示,PDPN過表達與患者預后不良密切相關,其介導的血小板聚集作用可能增加術后血栓風險。
近年針對PDPN的抗體藥物開發(fā)進展顯著,日本學者開發(fā)的NZ-1單抗已在動物實驗中成功抑制腫瘤轉移,CAR-T療法針對膠質瘤的臨床前研究也顯示出靶向潛力。然而,由于PDPN在正常組織如肺泡細胞中的基礎表達,藥物研發(fā)需重點解決靶向毒性問題。目前國際上有多個雙特異性抗體項目進入Ⅰ期臨床,試圖通過精確調控抗體親和力平衡療效與安全性。

CSB-RA017739MA1HU

IHC image of CSB-RA017739MA1HU diluted at 1:300 and staining in paraffin-embedded human colorectal cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-Mouse IgG labeled by HRP and visualized using 0.05% DAB.

IHC image of CSB-RA017739MA1HU diluted at 1:300 and staining in paraffin-embedded human placenta tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-Mouse IgG labeled by HRP and visualized using 0.05% DAB.

CSB-RA017739MA1HU

Overlay Peak curve showing 293 cells stained with CSB-RA017739MA1HU (red line) at 1:100. The cells were fixed in 4% formaldehyde (15min) and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-Mouse IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1μg/1*106cells) used under the same conditions. Acquisition of >10,026 events was performed.
