Extracellular pH impacts many molecular, cellular and physiological processes, and hence is tightly regulated. Yet, in tumours, dysregulated cancer cell metabolism and poor vascular perfusion cause the tumour microenvironment to become acidic. Here by leveraging fluorescent pH nanoprobes with a transistor-like activation profile at a pH of 5.3, we show that, in cancer cells, hydronium ions are excreted into a small extracellular region. Such severely polarized acidity (pH <5.3) is primarily caused by the directional co-export of protons and lactate, as we show for a diverse panel of cancer cell types via the genetic knockout or inhibition of monocarboxylate transporters, and also via nanoprobe activation in multiple tumour models in mice. We also observed that such spot acidification in ex vivo stained snap-frozen human squamous cell carcinoma tissue correlated with the expression of monocarboxylate transporters and with the exclusion of cytotoxic T cells. Severely spatially polarized tumour acidity could be leveraged for cancer diagnosis and therapy. Hydronium ions bordering cancer cells are highly concentrated into a small extracellular region, and in tumour tissue such severely polarized acidity correlates with the expression of monocarboxylate transporters and with the exclusion of cytotoxic T cells.
细胞外 pH 值对许多分子、细胞和生理过程都有影响,因此受到严格调控。然而,在肿瘤中,癌细胞代谢失调和血管灌注不良会导致肿瘤微环境呈酸性。在这里,我们利用荧光 pH 纳米探针在 pH 值为 5.3 时的类似晶体管的激活曲线,表明在癌细胞中,氢离子被排泄到一个小的细胞外区域。正如我们通过基因敲除或抑制单羧酸盐转运体,以及通过纳米探针激活小鼠的多种肿瘤模型所显示的那样,这种严重极化的酸度(pH<5.3)主要是由质子和乳酸盐的定向共输出引起的。我们还观察到,体内外染色速冻人类鳞状细胞癌组织中的这种斑点酸化与单羧酸盐转运体的表达和细胞毒性 T 细胞的排斥有关。严重空间极化的肿瘤酸度可用于癌症诊断和治疗。

Tumour-associated neutrophils can exert antitumour effects but can also assume a pro-tumoural phenotype in the immunosuppressive tumour microenvironment. Here we show that neutrophils can be polarized towards the antitumour phenotype by discoidal polymer micrometric ‘patches’ that adhere to the neutrophils’ surfaces without being internalized. Intravenously administered micropatch-loaded neutrophils accumulated in the spleen and in tumour-draining lymph nodes, and activated splenic natural killer cells and T cells, increasing the accumulation of dendritic cells and natural killer cells. In mice bearing subcutaneous B16F10 tumours or orthotopic 4T1 tumours, intravenous injection of the micropatch-loaded neutrophils led to robust systemic immune responses, a reduction in tumour burden and improvements in survival rates. Micropatch-activated neutrophils combined with the checkpoint inhibitor anti-cytotoxic T-lymphocyte-associated protein 4 resulted in strong inhibition of the growth of B16F10 tumours, and in complete tumour regression in one-third of the treated mice. Micropatch-loaded neutrophils could provide a potent, scalable and drug-free approach for neutrophil-based cancer immunotherapy. The intravenous injection of neutrophils bearing discoidal polymer microscale ‘patches’ on their surfaces reduces tumour burden in mice owing to the patch-induced polarization of the neutrophils towards an antitumour phenotype.
与肿瘤相关的中性粒细胞可以发挥抗肿瘤作用,但也可以在免疫抑制的肿瘤微环境中呈现出有利于肿瘤的表型。在这里,我们展示了中性粒细胞可以被盘状聚合物微米 "补丁 "极化为抗肿瘤表型,这些补丁附着在中性粒细胞表面而不被内化。静脉注射微补片的中性粒细胞会在脾脏和肿瘤排出的淋巴结中聚集,并激活脾脏的自然杀伤细胞和T细胞,增加树突状细胞和自然杀伤细胞的聚集。在携带皮下 B16F10 肿瘤或正位 4T1 肿瘤的小鼠中,静脉注射微补片装载的中性粒细胞可产生强大的全身免疫反应,减少肿瘤负荷,提高存活率。微补片激活的中性粒细胞与检查点抑制剂抗细胞毒性T淋巴细胞相关蛋白4结合使用,可有效抑制B16F10肿瘤的生长,三分之一的受试小鼠肿瘤完全消退。微补片装载的中性粒细胞可为基于中性粒细胞的癌症免疫疗法提供一种有效、可扩展且不含药物的方法。

The broader clinical use of bispecific T cell engagers for inducing anti-tumour toxicity is hindered by their on-target off-tumour toxicity and the associated neurotoxicity and cytokine-release syndrome. Here we show that the off-tumour toxicity of a supramolecular bispecific T cell engager binding to the T cell co-receptor CD3 and to the human epidermal growth factor receptor 2 on breast tumour cells can be halted by disengaging the T cells from the tumour cells via the infusion of the small-molecule drug amantadine, which disassembles the supramolecular aggregate. In mice bearing human epidermal growth factor receptor 2-expressing tumours and with a human immune system, high intravenous doses of such a ‘switchable T cell nanoengager’ elicited strong tumour-specific adaptive immune responses that prevented tumour relapse, while the infusion of amantadine restricted off-tumour toxicity, cytokine-release syndrome and neurotoxicity. Supramolecular chemistry may be further leveraged to control the anti-tumour activity and off-tumour toxicity of bispecific antibodies. The off-tumour toxicity of a supramolecular bispecific T cell engager can be halted by disengaging T cells from the tumour cells via the disassembly of the supramolecular aggregate through the infusion of the small-molecule drug amantadine.

In vitro systems that accurately model in vivo conditions in the gastrointestinal tract may aid the development of oral drugs with greater bioavailability. Here we show that the interaction profiles between drugs and intestinal drug transporters can be obtained by modulating transporter expression in intact porcine tissue explants via the ultrasound-mediated delivery of small interfering RNAs and that the interaction profiles can be classified via a random forest model trained on the drug–transporter relationships. For 24 drugs with well-characterized drug–transporter interactions, the model achieved 100% concordance. For 28 clinical drugs and 22 investigational drugs, the model identified 58 unknown drug–transporter interactions, 7 of which (out of 8 tested) corresponded to drug-pharmacokinetic measurements in mice. We also validated the model’s predictions for interactions between doxycycline and four drugs (warfarin, tacrolimus, digoxin and levetiracetam) through an ex vivo perfusion assay and the analysis of pharmacologic data from patients. Screening drugs for their interactions with the intestinal transportome via tissue explants and machine learning may help to expedite drug development and the evaluation of drug safety. A machine-learning model trained on interactions between oral drugs and intestinal drug transporters obtained by modulating their expression in intact porcine tissue can be used to predict drug–transporter and drug–drug interactions.

The blood–brain barrier (BBB) restricts the systemic delivery of messenger RNAs (mRNAs) into diseased neurons. Although leucocyte-derived extracellular vesicles (EVs) can cross the BBB at inflammatory sites, it is difficult to efficiently load long mRNAs into the EVs and to enhance their neuronal uptake. Here we show that the packaging of mRNA into leucocyte-derived EVs and the endocytosis of the EVs by neurons can be enhanced by engineering leucocytes to produce EVs that incorporate retrovirus-like mRNA-packaging capsids. We transfected immortalized and primary bone-marrow-derived leucocytes with DNA or RNA encoding the capsid-forming activity-regulated cytoskeleton-associated (Arc) protein as well as capsid-stabilizing Arc 5’-untranslated-region RNA elements. These engineered EVs inherit endothelial adhesion molecules from donor leukocytes, recruit endogenous enveloping proteins to their surface, cross the BBB, and enter the neurons in neuro-inflammatory sites. Produced from self-derived donor leukocytes, the EVs are immunologically inert, and enhanced the neuronal uptake of the packaged mRNA in a mouse model of low-grade chronic neuro-inflammation. The delivery of mRNAs into neurons at inflammatory sites in vivo can be enhanced by engineering leucocytes to produce extracellular vesicles incorporating mRNA-packaging retrovirus-like capsids.
血脑屏障(BBB)限制了将信使核糖核酸(mRNA)全身性地输送到患病神经元。虽然白细胞衍生的细胞外囊泡 (EV) 可以在炎症部位穿过 BBB,但很难将长 mRNA 有效地装载到 EV 中并提高神经元对它们的吸收。在这里,我们发现可以通过改造白细胞,使其产生包含类似逆转录病毒的mRNA包装囊的EVs,从而增强mRNA包装到白细胞衍生的EVs中以及神经元对EVs的内吞。我们用编码囊体形成活性调控细胞骨架相关蛋白(Arc)以及囊体稳定Arc 5'-非翻译区RNA元件的DNA或RNA转染了永生化和原发性骨髓衍生白细胞。这些工程化的 EV 继承了供体白细胞的内皮粘附分子,在其表面招募内源性包膜蛋白,穿过 BBB,进入神经炎症部位的神经元。在低度慢性神经炎症的小鼠模型中,由自身衍生的供体白细胞产生的EVs具有免疫惰性,能增强神经元对包装mRNA的吸收。
