2024年4月26日,武漢大學一研究團隊在Materials TodayIF=24.2)在線發表題為“Polydopamine-armed microalgal oxygenerator targeting the hypoxia-adenosine axis to boost cancer photothermal immunotherapy”的研究論文,此論文使用了聯科生物Mouse IFN-γ ELISA Kit(貨號:EK280),Mouse TNF-α ELISA Kit(貨號:EK282),Mouse IL-6 ELISA Kit(貨號:EK206)和Mouse IL-10 ELISA Kit(貨號:EK210)4種檢測試劑盒。

Fig.1 (f) IFN-γ, (g) TNF-α, (h) IL-6 and (i) IL-10 within tumors (n= 3). Tumors were collected at the sixth day for flowcytometric analysis after different treatments. Representative flow cytometric analysis images (left) and relative quantification analysis (right) of immune cellsas shown. G1, PBS; G2, PTA; G3, PTA + 660; G4, PTA + 808; G5, PTA + 660 + 808.

研究團隊開發了一種光熱微藻系統(PTA,以解決腫瘤微環境中缺氧導致的免疫抑制問題:

①使用了一種名為Chlorella sorokinianaC. soro)的微藻,通過在其表面涂覆一種名為聚多巴胺(PDA的光熱劑,構建了PTA。

②這種微藻系統能夠在660納米的光照下原位產生氧氣,減輕腫瘤缺氧情況,從而降低腺苷水平,逆轉腫瘤微環境中的免疫抑制。

③這種改變的腫瘤微環境促進了光熱療法(PTT)誘導的抗腫瘤免疫活性,這是通過808納米的光照下C. soro表面的PDA層實現的。

④在4T1腫瘤小鼠模型中,PTA顯著減弱了腫瘤微環境中的免疫抑制,引發了強烈的抗腫瘤免疫反應,抑制了腫瘤生長。

總之,該策略突出了利用活的光合微藻作為制氧機來促進癌癥光熱免疫治療的潛力。

Fig2.A microalgal oxygenerator (PTA) was developed by surface coating microalgae with the photothermal agent polydopamine. The PTA is capable of generating O2 in situ within the tumor through photosynthesis. This process effectively targets the hypoxia-adenosine axis, thereby reducing immunosuppression. The modification of the tumor microenvironment promotes antitumor immunity triggered by photothermal therapy and significantly improves antitumor efficiency.
