重慶大學(xué)附屬腫瘤醫(yī)院的李詠生教授團(tuán)隊(duì)通過(guò)對(duì)8536 種高置信度蛋白質(zhì)、1029種極性代謝物和 3381 種非冗余脂質(zhì)進(jìn)行了多組學(xué)分析,從蛋白質(zhì)組、代謝組和脂質(zhì)組等多個(gè)維度,描繪了肝細(xì)胞癌的多組學(xué)圖譜特征,并鑒定了3種肝癌亞型及2個(gè)潛在干預(yù)靶點(diǎn)。C1 亞型顯示核糖體生物合成富集,C2 亞型表現(xiàn)出中間表型,而 C3 亞型與中性粒細(xì)胞脫顆粒密切相關(guān)。此外,使用 PDO 檢測(cè),輸出蛋白 1 (XPO1) 和 5-脂氧合酶 (ALOX5) 分別被確定為 C1 和 C3 亞型的潛在靶點(diǎn)。靶點(diǎn):CD45
應(yīng)用:選擇性根除白血病細(xì)胞并保留造血功能

(體內(nèi)CIM053–SG3376介導(dǎo)的選擇性腫瘤根除,同時(shí)保留了編輯細(xì)胞中的造血功能[2])
造血干細(xì)胞移植(HSCT)是治療多種血液惡性腫瘤的唯一根治性療法,但標(biāo)準(zhǔn)治療依賴于無(wú)針對(duì)性的化療,并且在HSCT后治療惡性細(xì)胞的能力有限,不影響移植的健康細(xì)胞。作者展示了一種針對(duì)泛造血標(biāo)志物CD45的抗體藥物偶聯(lián)物(ADC),它能夠?qū)崿F(xiàn)整個(gè)造血系統(tǒng)的抗原特異性耗竭,包括造血干細(xì)胞。將這種ADC與移植經(jīng)過(guò)改造以抵御CD45靶向ADC的人類造血干細(xì)胞相結(jié)合,可以實(shí)現(xiàn)選擇性根除白血病細(xì)胞并保留造血功能。CD45靶向ADC與工程化造血干細(xì)胞的結(jié)合,創(chuàng)造了一種幾乎通用的策略,用以替代病變的造血系統(tǒng)。靶點(diǎn):PFKFB3
應(yīng)用:治療慢性腎病

(缺血-Q18Q19再灌注損傷(IRI)小鼠模型和慢性腎臟?。–KD)患者的腎小管細(xì)胞中6-磷酸果糖-2-激酶/果糖-2,6-二磷酸酶3(PFKFB3)上調(diào)[3])
中山一院腎內(nèi)科毛海萍、劉慶華、陳崴教授團(tuán)隊(duì)研究發(fā)現(xiàn),腎臟中持續(xù)增加的糖酵解活性,特別是關(guān)鍵酶PFKFB3的上調(diào),與慢性腎病的發(fā)展密切相關(guān)。通過(guò)減少PFKFB3活性,可以降低腎臟乳酸水平,減輕炎癥和纖維化,從而保護(hù)腎臟功能。此外,PFKFB3通過(guò)促進(jìn)乳酸化增強(qiáng)了NF-κB信號(hào)通路,這在調(diào)節(jié)炎癥反應(yīng)中起著關(guān)鍵作用。因此,靶向PFKFB3及其介導(dǎo)的信號(hào)通路可能為治療慢性腎病提供了一種新的治療策略。
靶點(diǎn):LILRB4
應(yīng)用:高風(fēng)險(xiǎn) 多發(fā)性骨髓瘤(MM)的免疫治療靶點(diǎn)
來(lái)源:LILRB4 represents a promising target for immunotherapy by dual targeting tumor cells and myeloid-derived suppressive cells in multiple myeloma. Haematologica, 2024 May 30.
(LILRB4 是一種很有前景的 MM 免疫療法靶標(biāo)[4])
多發(fā)性骨髓瘤 (MM) 仍然是一種無(wú)法治愈的血液系統(tǒng)惡性腫瘤。盡管治療取得了巨大進(jìn)展,但約 10% 的患者仍然預(yù)后不佳,中位總生存期不到 24 個(gè)月。中國(guó)醫(yī)學(xué)科學(xué)院血液病醫(yī)院郝牧/邱錄貴團(tuán)隊(duì)創(chuàng)新地生成了基于 TCR 的嵌合抗原受體 (CAR) T 細(xì)胞 LILRB4-STAR-T。細(xì)胞毒性實(shí)驗(yàn)表明 LILRB4-STAR-T 細(xì)胞有效消除腫瘤細(xì)胞并阻礙 MDSC 功能。該項(xiàng)研究闡明了 LILRB4 是高風(fēng)險(xiǎn) MM 的理想生物標(biāo)志物和有希望的免疫治療靶點(diǎn)。LILRB4-STAR-T 細(xì)胞免疫療法有望對(duì)抗 MM 中的腫瘤細(xì)胞和免疫抑制腫瘤微環(huán)境。靶點(diǎn):AURKA

(B 細(xì)胞惡性腫瘤中 CREBBP 和 AURKA 之間合成致死相互作用的示意模型[5])
中山大學(xué)腫瘤防治中心譚靜教授團(tuán)隊(duì)的研究顯示,在B細(xì)胞惡性腫瘤中,CREBBP基因失能突變常見,使其成為治療的新靶點(diǎn)。缺乏CREBBP的細(xì)胞對(duì)AURKA抑制特別敏感,且這種聯(lián)合靶向策略能通過(guò)降低MYC水平來(lái)引發(fā)復(fù)制應(yīng)激和細(xì)胞凋亡。AURKA抑制劑在體內(nèi)能有效延緩腫瘤進(jìn)展,與CREBBP抑制劑聯(lián)合使用時(shí),在CREBBP正常的細(xì)胞中具有協(xié)同效果。這些發(fā)現(xiàn)為攜帶CREBBP失活突變的高風(fēng)險(xiǎn)B細(xì)胞惡性腫瘤提供了一種新的治療策略,即靶向AURKA。靶點(diǎn):PDIA3

失調(diào)的 T 細(xì)胞活化是類風(fēng)濕性關(guān)節(jié)炎 (RA) 免疫病理學(xué)的基礎(chǔ),但協(xié)調(diào) T 細(xì)胞效應(yīng)程序的機(jī)制仍未完全了解。華中科技大學(xué)同濟(jì)醫(yī)學(xué)院附屬同濟(jì)醫(yī)院王從義教授團(tuán)隊(duì)與董凌莉教授課題組就蛋白質(zhì)二硫鍵異構(gòu)酶 A3 (PDIA3)對(duì)CD4 T細(xì)胞的功能調(diào)控及其在以類風(fēng)濕性關(guān)節(jié)炎為代表的自身免疫性疾病中的作用進(jìn)行了深入研究,其研究數(shù)據(jù)支持以 PDIA3 為靶點(diǎn)是臨床環(huán)境中緩解 RA 等自身免疫性疾病的重要策略。靶點(diǎn):mGluR2
應(yīng)用:介導(dǎo)流感病毒進(jìn)入宿主細(xì)胞的關(guān)鍵受體

(mGluR2 在流感病毒內(nèi)化過(guò)程中發(fā)揮著重要作用[7])
中國(guó)農(nóng)業(yè)科學(xué)院哈爾濱獸醫(yī)研究所步志高研究員、陳化蘭院士團(tuán)隊(duì)研究發(fā)現(xiàn)代謝型谷氨酸受體亞型 2 (mGluR2) 和鉀鈣激活通道亞家族 M alpha 1 (KCa1.1) 參與了流感病毒 CME 的啟動(dòng)和完成,使用 siRNA 篩選方法。流感病毒 HA 直接與 mGluR2 相互作用并將其用作內(nèi)吞受體來(lái)啟動(dòng) CME。mGluR2 相互作用并激活 KCa1.1,導(dǎo)致 F-肌動(dòng)蛋白聚合、網(wǎng)格蛋白小窩成熟并完成流感病毒的 CME。重要的是,mGluR2 基因敲除小鼠對(duì)不同流感亞型的抵抗力明顯高于野生型小鼠。因此,阻斷 HA 和 mGluR2 相互作用可能是一種有前途的宿主導(dǎo)向抗病毒策略。靶點(diǎn):VAMP2
