來源:Type 2 cytokines act on enteric sensory neurons to regulate neuropeptide-driven hostdefense.Science,2025 May 22

圖源:10.1126/science.adn9850[1]
2025年6月21日,哈佛醫(yī)學(xué)院團隊在《Science》發(fā)表研究,解析了腸道神經(jīng)元感知炎癥信號并調(diào)控免疫反應(yīng)的機制。研究發(fā)現(xiàn),腸道內(nèi)的初級感覺神經(jīng)元(PSN)能通過IL-13Rα1受體感知IL-4和IL-13細胞因子,進而釋放神經(jīng)肽U(NMU)和CGRPβ。這些神經(jīng)肽可增強腸道免疫反應(yīng),抵御腸道蠕蟲感染。利用基因敲除小鼠模型,研究證實了PSN在抗感染免疫中的關(guān)鍵作用,并揭示了其通過調(diào)節(jié)ILC2s細胞和巨噬細胞功能影響免疫防御的機制。這一發(fā)現(xiàn)為治療腸道炎癥和蠕蟲感染提供了新思路。02.靶點 CREM
應(yīng)用:CAR-NK細胞療法研究
來源:CREM is a regulatory checkpoint of CAR and IL-15 signalling in NK cells.Nature,2025 Jun 04

圖源:10.1038/s41586-025-09087-8[2]
這篇文章講的是免疫療法的新突破。研究人員發(fā)現(xiàn),在CAR-NK細胞療法中,NK細胞里的CREM是個關(guān)鍵調(diào)控因子。他們通過一系列實驗,比如基因工程改造NK細胞、用多種技術(shù)分析,發(fā)現(xiàn)CREM的表達受CAR激活和IL-15信號誘導(dǎo),且與NK細胞的激活等功能相關(guān)。敲除CREM能增強CAR-NK細胞的抗腫瘤能力,為這種療法的發(fā)展帶來新希望。
03.靶點 PVR/CD155
應(yīng)用:血液瘤和實體瘤治療
來源:Pan-cancer analysis identifies CD155 as a promising target for CAR-T cell therapy.Genome Med,2025 Jun 02

圖源:10.1186/s13073-025-01490-0[3]
華東師范大學(xué)杜冰團隊發(fā)現(xiàn),CD155在多種癌癥組織中高表達,且與癌癥患者不良預(yù)后相關(guān),其通過抑制T細胞釋放細胞毒性因子介導(dǎo)腫瘤免疫逃逸。該團隊構(gòu)建的靶向CD155的CAR-T細胞在體內(nèi)外多種血液瘤和實體瘤中展現(xiàn)出顯著抗腫瘤活性,且在動物模型中未見明顯副作用,表明CD155有望成為CAR-T療法的理想靶點。
04.靶點 R9AP
應(yīng)用:抗EBV疫苗的研究
來源:R9AP is a common receptor for EBV infection in epithelial cells and B cells.Nature,2025 Jun 18

圖源:10.1038/s41586-025-09166-w[4]
中山大學(xué)曾木圣、鐘茜團隊在《Nature》發(fā)文,發(fā)現(xiàn)R9AP是EB病毒(EBV)感染上皮細胞和B淋巴細胞的通用受體。EBV與多種疾病相關(guān),但此前對上皮細胞感染研究較少。該團隊通過構(gòu)建高效感染模型,篩選發(fā)現(xiàn)R9AP在兩種細胞中均表達且對EBV感染至關(guān)重要。R9AP與EBV糖蛋白gH/gL結(jié)合,沉默或敲除R9AP可顯著抑制感染。這一發(fā)現(xiàn)顛覆了EBV利用不同受體感染兩類細胞的傳統(tǒng)認知,為抗EBV疫苗研發(fā)提供了新靶標。
05.靶點 TNFR2
應(yīng)用:結(jié)直腸癌免疫治療
來源:Dual blockade of TNFR2 and CD47 reshape tumor immune microenvironment and improve antitumor effects in colorectal cancer.Mol Ther,2025 May 30

圖源:10.1016/j.ymthe.2025.05.032[5]
南京大學(xué)魏繼武團隊在《Molecular Therapy》發(fā)表研究,提出一種針對結(jié)直腸癌的新型免疫治療策略。該策略通過構(gòu)建雙特異性融合抗體ATA47,同時阻斷CD47與TNFR2信號通路,并利用溶瘤腺病毒載體實現(xiàn)腫瘤原位遞送。此方法有效重塑腫瘤免疫微環(huán)境,增強抗腫瘤免疫,克服了傳統(tǒng)CD47阻斷療法的療效限制和副作用問題,為結(jié)直腸癌免疫治療提供了新路徑。
06.靶點 STING
應(yīng)用:腸道疾病的治療
來源:ILC3s sense gut microbiota through STING to initiate immune tolerance.Immunity,2025 Jul 08

圖源:10.1016/j.immuni.2025.05.016[6]
康奈爾大學(xué)團隊在《Immunity》發(fā)表研究,發(fā)現(xiàn)III型天然淋巴細胞(ILC3s)通過STING感知腸道菌群,促進免疫耐受并維持腸道穩(wěn)態(tài)。研究揭示了ILC3s中STING的適度激活可啟動免疫耐受,而過度激活則會導(dǎo)致ILC3死亡,與炎癥性腸病(IBD)相關(guān)。這一發(fā)現(xiàn)為腸道疾病的治療提供了新思路。07.靶點 SELPLG/PSGL1
應(yīng)用:血癌免疫研究
來源:Cisplatin and temozolomide combinatorial treatment triggers hypermutability and immune surveillance in experimental cancer models.Cancer Cell,2025 Jun 10
