Cell Membrane-Coated Nanoparticles for Precision Medicine: A Comprehensive Review of Coating Techniques for Tissue-Specific Therapeutics. Int J Mol Sci 2024; 25:2071. [PMID: 38396747 PMCID: PMC10889273 DOI: 10.3390/ijms25042071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 02/01/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
Nanoencapsulation has become a recent advancement in drug delivery, enhancing stability, bioavailability, and enabling controlled, targeted substance delivery to specific cells or tissues. However, traditional nanoparticle delivery faces challenges such as a short circulation time and immune recognition. To tackle these issues, cell membrane-coated nanoparticles have been suggested as a practical alternative. The production process involves three main stages: cell lysis and membrane fragmentation, membrane isolation, and nanoparticle coating. Cell membranes are typically fragmented using hypotonic lysis with homogenization or sonication. Subsequent membrane fragments are isolated through multiple centrifugation steps. Coating nanoparticles can be achieved through extrusion, sonication, or a combination of both methods. Notably, this analysis reveals the absence of a universally applicable method for nanoparticle coating, as the three stages differ significantly in their procedures. This review explores current developments and approaches to cell membrane-coated nanoparticles, highlighting their potential as an effective alternative for targeted drug delivery and various therapeutic applications.

Microglia Polarization and Antiglioma Effects Fostered by Dual Cell Membrane-Coated Doxorubicin-Loaded Hexagonal Boron Nitride Nanoflakes. ACS APPLIED MATERIALS & INTERFACES 2023; 15:58260-58273. [PMID: 38051559 PMCID: PMC10739601 DOI: 10.1021/acsami.3c17097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 11/17/2023] [Accepted: 11/17/2023] [Indexed: 12/07/2023]
Abstract
Microglial cells play a critical role in glioblastoma multiforme (GBM) progression, which is considered a highly malignant brain cancer. The activation of microglia can either promote or inhibit GBM growth depending on the stage of the tumor development and on the microenvironment conditions. The current treatments for GBM have limited efficacy; therefore, there is an urgent need to develop novel and efficient strategies for drug delivery and targeting: in this context, a promising strategy consists of using nanoplatforms. This study investigates the microglial response and the therapeutic efficacy of dual-cell membrane-coated and doxorubicin-loaded hexagonal boron nitride nanoflakes tested on human microglia and GBM cells. Obtained results show promising therapeutic effects on glioma cells and an M2 microglia polarization, which refers to a specific phenotype or activation state that is associated with anti-inflammatory and tissue repair functions, highlighted through proteomic analysis.

Promoting Intratumoral Drug Accumulation by Bio-Membrane Regulated Active Targeting for Tumor Photothermal Therapy. Int J Nanomedicine 2023; 18:7287-7304. [PMID: 38076730 PMCID: PMC10710258 DOI: 10.2147/ijn.s434645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 11/28/2023] [Indexed: 12/18/2023] Open
Abstract
Introduction Insufficient tumor permeability and inadequate nanoparticle retention continue to be significant limitations in the efficacy of anti-tumor drug therapy. Numerous studies have focused on enhancing tumor perfusion by improvement of tumor-induced endothelial leakage, often known as the enhanced permeability and retention (EPR) effect. However, these approaches have produced suboptimal therapeutic outcomes and have been associated with significant side effects. Therefore, in this study, we prepared tumor cell membrane-coated gold nanorods (GNR@TM) to enhance drug delivery in tumors through homogeneous targeting of tumor cell membranes and in situ real-time photo-controlled therapy. Methods Here, we fabricated GNR@TM, and characterized it using various techniques including Ultraviolet-Visible (UV-Vis) spectrophotometer, particle size analysis, potential measurement, and transmission electron microscopy (TEM). The cellular uptake and cytotoxicity of GNR@TM were analyzed by flow cytometry, confocal laser scanning microscopy (CLSM), TEM, CCK8 assay and live/dead staining. Tissue drug distribution was determined by inductively coupled plasma mass spectrometry (ICP-MS) and immunofluorescence staining. Furthermore, to evaluate the therapeutic effect, mice bearing MB49 tumors were intravenously administered with GNR@TM. Subsequently, near-infrared (NIR) laser therapy was performed, and the mice's tumor growth and body weight were monitored. Results The tumor cell membrane coating endowed GNR@TM with extended circulation time in vivo and homotypic targeting to tumor, thereby enhancing the accumulation of GNR@TM within tumors. Upon 780 nm laser, GNR@TM exhibited excellent photothermal conversion capability, leading to increased tumor vascular leakage. This magnification of the EPR effect induced by NIR laser further increased the accumulation of GNR@TM at the tumor site, demonstrating strong antitumor effects in vivo. Conclusion In this study, we successfully developed a NIR-triggered nanomedicine that increased drug accumulation in tumor through photo-controlled therapy and homotypic targeting of the tumor cell membrane. GNR@TM has been demonstrated effective suppression of tumor growth, excellent biocompatibility, and significant potential for clinical applications.

Cancer Immunotherapy Based on Cell Membrane-Coated Nanocomposites Augmenting cGAS/STING Activation by Efferocytosis Blockade. SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2023; 19:e2302758. [PMID: 37381095 DOI: 10.1002/smll.202302758] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 06/07/2023] [Indexed: 06/30/2023]
Abstract
Innate immunity triggered by the cGAS/STING pathway has the potential to improve cancer immunotherapy. Previously, the authors reported that double-stranded DNA (dsDNA) released by dying tumor cells can trigger the cGAS/STING pathway. However, owing to efferocytosis, dying tumor cells are engulfed and cleared before the damaged dsDNA is released; hence, immunologic tolerance and immune escape occur. Herein, a cancer-cell-membrane biomimetic nanocomposites that exhibit tumor-immunotherapeutic effects are synthesized by augmenting the cGAS/STING pathway and suppressing efferocytosis. Once internalized by cancer cells, a combined chemo/chemodynamic therapy would be triggered, which damages their nuclear and mitochondrial DNA. Furthermore, the releasing Annexin A5 protein could inhibit efferocytosis effect and promote immunostimulatory secondary necrosis by preventing phosphatidylserine exposure, resulting in the burst release of dsDNA. These dsDNA fragments, as molecular patterns to immunogenic damage, escape from the cancer cells, activate the cGAS/STING pathway, enhance cross-presentation inside dendritic cells, and promote M1-polarization of tumor-associated macrophages. In vivo experiments suggest that the proposed nanocomposite could recruit cytotoxic T-cells and facilitate long-term immunological memory. Moreover, when combined with immune-checkpoint blockades, it could augment the immune response. Therefore, this novel biomimetic nanocomposite is a promising strategy for generating adaptive antitumor immune responses.

A Novel Patient-Personalized Nanovector Based on Homotypic Recognition and Magnetic Hyperthermia for an Efficient Treatment of Glioblastoma Multiforme. Adv Healthc Mater 2023:e2203120.

Abstract
Glioblastoma multiforme (GBM) is the deadliest brain tumor, characterized by an extreme genotypic and phenotypic variability, besides a high infiltrative property in healthy tissues. Apart from very invasive surgical procedures, to date, there are no effective treatments, and life expectancy is very limited. In this work, we propose an innovative therapeutic approach based on lipid-based magnetic nanovectors, owning a dual therapeutic function: chemotherapy, thanks to an antineoplastic drug (regorafenib) loaded in the core, and localised magnetic hyperthermia, thanks to the presence of iron oxide nanoparticles, remotely activated by an alternating magnetic field. The drug has been selected based on ad hoc patient-specific screenings; moreover, the nanovector is decorated with cell membranes derived from patients' cells, aiming at increasing homotypic and personalized targeting. We demonstrated that this functionalization not only enhances the selectivity of the nanovectors towards patient-derived GBM cells, but also their blood-brain barrier in vitro crossing ability. The localised magnetic hyperthermia induces both thermal and oxidative intracellular stress, that lead to lysosomal membrane permeabilization and release of proteolytic enzymes into the cytosol. Collected results show that hyperthermia and chemotherapy work in synergy to reduce GBM cell invasion properties, to induce intracellular damage and, eventually, to prompt cellular death.

Reactive oxygen species / photothermal therapy dual-triggered biomimetic gold nanocages nanoplatform for combination cancer therapy via ferroptosis and tumor-associated macrophage repolarization mechanism. J Colloid Interface Sci 2022; 606:1950-1965. [PMID: 34695762 DOI: 10.1016/j.jcis.2021.09.160] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 09/06/2021] [Accepted: 09/26/2021] [Indexed: 12/12/2022]
Abstract
With the continuous development of cancer nanotechnology, an important trend in the research is to combine the broad application prospects of functional nanomaterials with recent biological discoveries and technological advances. Herein, a cancer cell membrane-camouflaged gold nanocage loading doxorubicin (DOX) and l-buthionine sulfoximine (BSO) (denoted as m@Au-D/B NCs) was constructed as an innovative nanoplatform to confer promising cancer combination therapy by evoking effective ferroptosis and immune responses. Briefly, the loading of BSO and DOX could induce ferroptosis through simultaneous effective glutathione (GSH) consumption and reactive oxygen species (ROS) accumulation. Gold nanocages (AuNCs) with distinct anti-tumor application performance was utilized as ideal nanocarrier for drug loading, evoking photothermal effects and photochemical catalysis to generate more ROS under near-infrared (NIR) irradiation. Moreover, m@Au-D/B NCs-mediated photothermal therapy (PTT) combined with ROS production could repolarize the tumor-associated macrophages (TAMs) from pro-tumor (M2) phenotype to anti-tumor (M1) phenotype, thus improving tumor-suppressive immune environment and then promoting the activation of effector cells and release of pro-inflammatory cytokines, in which the antitumor responses were evoked robustly in a methodical approach. The anti-tumor effects in vivo implied that m@Au-D/B NCs could significantly inhibit tumor growth without severe toxicity. Hence, this homotypic targeting nanosystem could offer an auspicious anticancer access by triggering combination cancer therapy via ferroptosis and tumor-associated macrophage repolarization mechanism.

Cancer Cell Membrane-Coated Nanosuspensions for Enhanced Chemotherapeutic Treatment of Glioma. Molecules 2021; 26:5103.

Abstract
Effective intracerebral delivery is key for glioma treatment. However, the drug delivery system within the brain is largely limited by its own adverse physical and chemical properties, low targeting efficiency, the blood-brain barrier and the blood-brain tumor barrier. Herein, we developed a simple, safe and efficient biomimetic nanosuspension. The C6 cell membrane (CCM) was utilized to camouflaged the 10-hydroxycamptothecin nanosuspension (HCPT-NS) in order to obtain HCPT-NS/CCM. Through the use of immune escape and homotypic binding of the cancer cell membrane, HCPT-NS/CCM was able to penetrate the blood-brain barrier and target tumors. The HCPT-NS is only comprised of drugs, as well as a small amount of stabilizers that are characterized by a simple preparation method and high drug loading. Similarly, the HCPT-NS/CCM is able to achieve targeted treatment of glioma without any ligand modification, which leads it to be stable and efficient. Cellular uptake and in vivo imaging experiments demonstrated that HCPT-NS/CCM is able to effectively cross the blood-brain barrier and was concentrated at the glioma site due to the natural homing pathway. Our results reveal that the glioma cancer cell membrane is able to promote drug transport into the brain and enter the tumor via a homologous targeting mechanism.

Abstract
OBJECTIVE The purpose of this research is to formulate a biomimetic drug delivery system that can selectively target glioblastoma (GBM) to deliver the antitumor agent, Gboxin: a novel Complex V inhibitor. Gboxin can specifically inhibit GBM cell growth but not normal cells. METHODS In the present study, we utilized Red Blood Cell (RBC) membrane and U251 cell membrane to obtain a hybrid biomimetic membrane (RBC-U), and prepared RBC-U coated Gboxin-loaded mesoporous silica nanoparticles ((MSNs/Gboxin)@[RBC-U]) for GBM chemotherapy. The zeta potential, particle size, and morphology of (MSNs/Gboxin)@[RBC-U] were characterized. The cellular uptake, effect of cells growth inhibition, biocompatibility, and specific self-recognition of nanoparticles were evaluated. RESULTS The (MSNs/Gboxin)@[RBC-U] was successfully fabricated and possessed high stability in the circulation system. The drug loading of Gboxin was 13.9%. (MSNs/Gboxin)@[RBC-U], effectively retain drugs in the physiological environment and releasing Gboxin rapidly in the tumor cells. Compared to the MSNs/Gboxin, the (MSNs/Gboxin)@[RBC-U] exhibited highly specific self-recognition to the source cell line. Additionally, the (MSNs/Gboxin)@[RBC-U] showed excellent anti-proliferation efficiency (IC50 = 0.21 μg/mL) in the tumor cell model and a few side effects in normal cells in vitro. CONCLUSION The (MSNs/Gboxin)@[RBC-U] exhibited significant anti-cancer effects in vitro and the specific self-recognition to GBM cells. Hence, (MSNs/Gboxin)@[RBC-U] could be a promising delivery system for GBM targeted therapy.

Abstract
Although photothermal therapy (PTT) has great potential for tumor inhibition, this single mode of action frequently encounters recurrence and metastasis, highlighting the urgent need for developing combination therapy. Inspired by established evidence that PTT could induce efficient immunogenic cell death (ICD), we here developed a versatile biomimetic nanoplatform (denoted as AuDRM) for the synergism of photothermal/starvation/immunotherapy against cancer. Specifically, dendritic mesoporous silica nanoparticles (NPs) were successfully constructed followed by the in situ synthesis of Au NPs in the mesopores. Afterward, a hybrid membrane was coated to facilitate the loading of R837. Upon efficient accumulation in the tumor tissue by homotypic targeting, the pH-sensitive membrane could be jettisoned to ensure the exposure of Au NPs for starvation therapy and the effective release of the immunostimulator R837 for enhancement of immunotherapy. Except for the PTT-mediated tumor ablation, the induction of ICD coupled with the release of tumor antigens could work synergistically with the immunostimulator R837 for inhibiting the primary tumor as well as the metastasis and induce a long-term immune memory effect for tumor inhibition via a vaccine-like function. Thus, this study paves the way for high-performance tumor ablation by the synergism of photothermal/starvation/immunotherapy.

Abstract
Development of intelligent and multifunctional nanoparticle for the diagnosis and treatment of cancer has drawn great attention recently. In this work, we design a smart two-dimensional (2D) supraparticle for tumor targeted magnetic resonance imaging (MRI)/photothermal imaging (PTI) and chemo/photothermal therapy (PTT). Methods: The nanoparticle consists of a manganese dioxide (MnO2) nanosheet coated gold nanorod (GNR) core (loading with chemotherapeutics doxorubicin (DOX)), and cancer cell membrane shell (denoted as CM-DOX-GMNPs). Decoration of cell membrane endows the nanoparticle with greatly improved colloidal stability and homotypic cancer cell targeting ability. Once the nanoparticles enter tumor cells, MnO2 nanosheets can be etched to Mn2+ by glutathione (GSH) and acidic hydrogen peroxide (H2O2) in the cytosol, leading to the release of DOX. Meanwhile, stimuli dependent releasing of Mn2+ can act as MRI contrast agent for tumor diagnosis. Illumination with near-infrared (NIR) light, photothermal conversion effect of GNRs can be activated for synergistic cancer therapy. Results:In vivo results illustrate that the CM-DOX-GMNPs display tumor specific MRI/PTI ability and excellent inhibition effect on tumor growth. Conclusion: This bioinspired nanoparticle presents an effective and intelligent approach for tumor imaging and therapy, affording valuable guidance for the rational design of robust theranostics nanoplatform.

Abstract
Conventional chemotherapy usually induces significant side effects due to its inability to discriminate between cancer and normal cells. Moreover, the efficacy of cancer elimination is still unsatisfied. Here, we fabricated a nanocomposite enabling high-performance dual combination therapy (chemo/photothermal therapy). This style of novel nanocomposites was constructed with doxorubicin (DOX)-loaded mesoporous silica gold (MSG) nanorods, which were further camouflaged with hybrid membranes derived from HeLa cells and red blood cells (HRMSGD). The hybrid membrane-camouflaged structure showed enhanced circulation lifetime and cell line-specific delivery of chemotherapeutics both in vitro and in vivo. The dual combination therapy by HRMSGD showed an unattainable therapeutic effect, compared with a single treatment, and inhibited tumor growth significantly. Furthermore, the nanoplatforms were photoacoustic-responsive, which showed real-time and noninvasive tracking capability. The present study established nanoplatforms with hybrid cell membrane-camouflaged multifunctional gold nanorods, which realized the combination of homotypic targeting, noninvasive tracking, chemotherapy, and photothermal therapy. To the best of our knowledge, this is the first study to use a natural membrane to camouflage mesoporous silica-modified gold nanorods, which opened a new avenue for cancer treatment.

Abstract
Our exploration of multimodal nanoprobes aims to combine photoacoustic (PA) imaging, 19F magnetic resonance (MR), and fluorescence (FL) imaging, which offers complementary advantages such as high spatial resolution, unlimited penetration, and high sensitivity to enable more refined images for accurate tumor diagnoses. In this research, perfluorocarbons (PFCs) and indocyanine green (ICG) are encapsulated by poly(lactic-co-glycolic acid) (PLGA) for intravital 19F MR/FL/PA tri-modal imaging-guided photothermal therapy. Then, it is coated with an A549 cancer cell membrane (AM) to fabricate versatile theranostic nanoprobes (AM-PP@ICGNPs). After systemic administration, FLI reveals time-dependent tumor homing of NPs with high sensitivity, 19F MRI provides tumor localization of NPs without background signal interference, and PAI illustrates the detailed distribution of NPs inside the tumor with high spatial resolution. What is more, AM-PP@ICGNPs accumulated in the tumor area exhibit a prominent photothermal effect (48.4 °C) under near infrared (NIR) laser irradiation and realize an enhanced antitumor response in vivo. These benefits, in combination with the excellent biocompatibility, make AM-PP@ICGNPs a potential theranostic nanoagent for accurate tumor localization and ultimately achieve superior cancer therapy.

Abstract
Organic-inorganic hybrid materials have drawn increasing attention as photothermal agents in tumor therapy due to the advantages of green synthesis, high loading efficiency of hydrophobic drugs, facile incorporation of theranostic iron, and excellent photothermal efficiency without inert components or additives. Herein, we proposed a strategy for biomimetic engineering-mediated enhancement of photothermal performance in the tumor microenvironment (TME). This strategy is based on the specific characteristics of organic-inorganic hybrid materials and endows these materials with homologous targeting ability and photothermal stability in the TME. The hybrid materials perform the functions of cancer cells to target homolytic tumors (acting as "artificial nanotargeted cells (ANTC)"). Inspired by the pH-dependent disassembly behaviors of tannic acid (TA) and ferric ion (FeIII) and subsequent attenuation of photothermal performance, cancer cell membranes were self-deposited onto the surfaces of protoporphyrin-encapsulated TA and FeIII nanoparticles to achieve ANTC with TME-stable photothermal performance and tumor-specific phototherapy. The resulting ANTC can be used as contrast agents for concurrent photoacoustic imaging, magnetic resonance imaging, and photothermal imaging to guide the treatment. Importantly, the high loading efficiency of protoporphyrin enables the initiation of photodynamic therapy to enhance photothermal therapeutic efficiency, providing antitumor function with minimal side effects.

Abstract
Cell-membrane-camouflaged nanoparticles (CMC-NPs) have been increasingly exploited to develop various therapeutic tools due to their high biocompatibility and cell-type-specific tumor-targeting properties. However, the molecular mechanism of CMC-NPs for homotypic targeting remains elusive. Here, we develop a plasmonic imaging method by coating gold nanoparticles (AuNPs) with cancer cell membranes and perform plasmonic imaging of the interactions between CMC-NPs and living cells at the single-cell level. Quantitative analysis of CMC-NPs in a different clustering status reveals that the presence of cell membranes on CMC-NPs results in a 7-fold increase in homotypic cell delivery and nearly 2 orders of magnitude acceleration of the intracellular agglomeration process. Significantly, we identify that integrin αvβ3, a cell surface receptor abundantly expressed in tumor cells, is critical for the selective cell recognition of CMC-NPs. We thus establish a single-cell plasmonic imaging platform for probing NP-cell interactions, which sheds new light on the therapeutic applications of CMC-NPs.

Abstract
Nanoparticle-based drug delivery systems with low side effects and enhanced efficacy hold great potential in the treatment of various malignancies, in particular cancer; however, they are still challenging to attain. Herein, an anticancer drug delivery system based on a cisplatin (CDDP) containing nanogel, functionalized with photothermal gold nanorods (GNRs) which are electrostatically decorated with doxorubicin (DOX) is reported. The nanoparticles are formed via the crosslinking reaction of hyaluronic acid with the ancillary anticarcinogen CDDP in the presence of DOX-decorated GNRs. The nanogel is furthermore cloaked with a cancer cell membrane, and the resulting biomimetic nanocarrier (4T1-HANG-GNR-DC) shows efficient accumulation by homologous tumor targeting and possesses long-time retention in the tumor microenvironment. Upon near-infrared (NIR) laser irradiation, in situ photothermal therapy is conducted which further induces hyperthermia-triggered on-demand drug release from the nanogel reservoir to achieve a synergistic photothermal/chemo-therapy. The as-developed biomimetic nanocarriers, with their dual-drug delivery features, homotypic tumor targeting and synergetic photothermal/chemo-therapy, show much promise as a potential platform for cancer treatment.

Abstract
The camouflage with cell membrane bestows nanoparticles with cell-like functions, such as specific recognition, long blood circulation, and immune escaping. For cancer therapy, the nanoparticles camouflaged with cancer cell membrane (CCM) from homologous cells show homotypic targeting delivery of small molecule compounds, photosensitizers, or enzymes to the tumors. However, effective gene therapy encounters difficulties by this approach due to the properties of nucleic acids. Herein, a cancer cell-like gene delivery system is developed using an excellent polymer poly(β-amino ester) (PBAE) to condense small interfering RNA (siRNA) (targeting to Plk1 gene) into nanoparticles (PBAE/siPlk1) as the core, which is further camouflaged with CCM. These novel biomimetic nanoparticles CCM/PBAE/siPlk1 (CCMPP) demonstrate highly specific targeting to homotypic cancer cells, effective downregulation of PLK1 level, and inducing apoptosis of cancer cells. Based on the homotypic binding adhesion molecules on the CCM, the cellular internalization and homotypic-targeting accumulation to the tumors are clearly improved. CCMPP induces highly efficient apoptosis of cancer cells both in vitro and in vivo and results in significant tumor inhibition. The artificial cancer cells with homotypic properties can serve as a biomimetic delivery system for cancer-targeted gene therapy.

[PMID: 32194871 PMCID: PMC7053183 DOI: 10.7150/thno.41228] [Citation(s) in RCA: 58] [Impact Index Per Article: 14.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Accepted: 01/20/2020] [Indexed: 11/21/2022] Open
Abstract
Because of the complexity of cancer, a combination of chemotherapy and gene therapy is an emerging treatment modality. To realize the full potential of this strategy, a smart, highly biocompatible nanosystem that enables the precise co-delivery of small-molecule anticancer drugs and small interfering RNA (siRNA) is urgently needed. This study aimed to improve the therapeutic effect against cervical cancer by using cancer cell membrane-camouflaged nanoparticles for simultaneous delivery of paclitaxel (PTX) and siRNA targeting E7. Methods: By camouflaging HeLa cell membranes onto siRNA/PTX co-loaded (lactic-co-glycolic acid) (PLGA) nanoparticles, a biomimetic dual-drug delivery system (Si/PNPs@HeLa) was developed to simultaneously deliver PTX and siRNA targeting E7. After evaluating the physicochemical characteristics as well as their cell uptake and biodistribution behavior, studies on the RNA interference efficiency and antitumor ability of Si/PNPs@HeLa in vitro and in vivo were further carried out. Results: The Si/PNPs@HeLa was capable of delivering PTX and siRNA simultaneously to HeLa cells both in vitro and in vivo. Moreover, benefiting from the recognition and adhesion molecules on the surface of HeLa cells, Si/PNPs@HeLa exhibited an improved immune escape ability and an increased tumor region accumulation (3-fold higher than bare nanoparticles). As a result, an excellent synergistic anti-tumor effect was observed in the HeLa tumor-bearing mice, with tumor volume inhibiting rates of 83.6% and no side effects in major organs. The mechanistic studies confirmed that E7 knockdown sensitized HeLa cells to PTX chemotherapy, mainly by inhibiting PTX-induced AKT pathway activation. Conclusion: Si/PNPs@HeLa, by integrating immune escape and tumor-homing ability, can serve as an efficient dual-drug delivery system to achieve precise treatment of cervical cancer through chemo-gene combined therapy.

Cell Membrane-Coated Magnetic Nanocubes with a Homotypic Targeting Ability Increase Intracellular Temperature due to ROS Scavenging and Act as a Versatile Theranostic System for Glioblastoma Multiforme. Adv Healthc Mater 2019; 8:e1900612. [PMID: 31389193 PMCID: PMC6754263 DOI: 10.1002/adhm.201900612] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 07/15/2019] [Indexed: 12/15/2022]
Abstract
In this study, hybrid nanocubes composed of magnetite (Fe3 O4 ) and manganese dioxide (MnO2 ), coated with U-251 MG cell-derived membranes (CM-NCubes) are synthesized. The CM-NCubes demonstrate a concentration-dependent oxygen generation (up to 15%), and, for the first time in the literature, an intracellular increase of temperature (6 °C) due to the exothermic scavenging reaction of hydrogen peroxide (H2 O2 ) is showed. Internalization studies demonstrate that the CM-NCubes are internalized much faster and at a higher extent by the homotypic U-251 MG cell line compared to other cerebral cell lines. The ability of the CM-NCubes to cross an in vitro model of the blood-brain barrier is also assessed. The CM-NCubes show the ability to respond to a static magnet and to accumulate in cells even under flowing conditions. Moreover, it is demonstrated that 500 µg mL-1 of sorafenib-loaded or unloaded CM-NCubes are able to induce cell death by apoptosis in U-251 MG spheroids that are used as a tumor model, after their exposure to an alternating magnetic field (AMF). Finally, it is shown that the combination of sorafenib and AMF induces a higher enzymatic activity of caspase 3 and caspase 9, probably due to an increment in reactive oxygen species by means of hyperthermia.

Immunomodulatory Lipocomplex Functionalized with Photosensitizer-Embedded Cancer Cell Membrane Inhibits Tumor Growth and Metastasis. NANO LETTERS 2019; 19:5185-5193.

Abstract
Liposomes are clinically used as drug carriers for cancer therapy; however, unwanted leakage of the encapsulated anticancer drug and poor tumor-targeting efficiency of liposomes may generate toxic side effects on healthy cells and lead to failure of tumor eradication. To overcome these limitations, we functionalized liposomes with a photosensitizer (KillerRed, KR)-embedded cancer cell membrane (CCM). A lipid adjuvant was also embedded in the lipocomplex to promote the anticancer immune response. KR proteins were expressed on CCM and did not leak from the lipocomplex. Owing to the homotypic affinity of the CCM for the source cancer cells, the lipocomplex exhibited a 3.3-fold higher cancer-targeting efficiency in vivo than a control liposome. The liposome functionalized with KR-embedded CCM and lipid adjuvant generated cytotoxic reactive oxygen species in photodynamic therapy and effectively induced anticancer immune responses, inhibiting primary tumor growth and lung metastasis in homotypic tumor-bearing mice. Taken together, the lipocomplex technology may improve liposome-based cancer therapy.

Abstract
Nanoparticles coated with cell membranes have been garnering growing attention due to their homologous binding capability of membrane molecules and consequent self-recognition by their source cells. In the present study, we report on the construction of doxorubicin and PD-L1 siRNA-loaded PLGA nanoparticles and their biological functionalization by cancer cell-derived membrane cloaking. The resulting cancer cell membrane-coated nanoparticles (CCMNPs) presented a core-shell nanostructure with highly specific self-recognition affinity to the homotypic cells, which can be attributed to the transference of cell adhesion molecules with homotypic binding properties. These findings facilitate the application of this bioinspired strategy for effective delivery of siRNA and precise tumour therapy.

Cell Membrane-Camouflaged NIR II Fluorescent Ag 2 Te Quantum Dots-Based Nanobioprobes for Enhanced In Vivo Homotypic Tumor Imaging. Adv Healthc Mater 2019; 8:e1900341.

Abstract
The advantages of fluorescence bioimaging in the second near-infrared (NIR II, 1000-1700 nm) window are well known; however, current NIR II fluorescent probes for in vivo tumor imaging still have many shortcomings, such as low fluorescence efficiency, unstable performance under in vivo environments, and inefficient enrichment at tumor sites. In this study, Ag2 Te quantum dots (QDs) that emit light at a wavelength of 1300 nm are assembled with poly(lactic-co-glycolic acid) and further encapsulated within cancer cell membranes to overcome the shortcomings mentioned above. The as-prepared ≈100 nm biomimetic nanobioprobes exhibit ultrabright (≈60 times greater than that of free Ag2 Te QDs) and highly stable (≈97% maintenance after laser radiation for 1 h) fluorescence in the NIR II window. By combining the active homotypic tumor targeting capability derived from the source cell membrane with the passive enhanced permeation and retention effect, improved accumulation at tumor sites ((31 ± 2)% injection dose per gram of tumor) and a high tumor-to-normal tissue ratio (13.3 ± 0.7) are achieved. In summary, a new biomimetic NIR II fluorescent nanobioprobe with ultrabright and stable fluorescence, homotypic targeting and good biocompatibility for enhanced in vivo tumor imaging is developed in this study.

Expandable Immunotherapeutic Nanoplatforms Engineered from Cytomembranes of Hybrid Cells Derived from Cancer and Dendritic Cells. ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2019; 31:e1900499.

Abstract
Using the cytomembranes (FMs) of hybrid cells acquired from the fusion of cancer and dendritic cells (DCs), this study offers a biologically derived platform for the combination of immunotherapy and traditional oncotherapy approaches. Due to the immunoactivation implicated in the cellular fusion, FMs can effectively express whole cancer antigens and immunological co-stimulatory molecules for robust immunotherapy. FMs share the tumor's self-targeting character with the parent cancer cells. In bilateral tumor-bearing mouse models, the FM-coated nanophotosensitizer causes durable immunoresponse to inhibit the rebound of primary tumors post-nanophotosensitizer-induced photodynamic therapy (PDT). The FM-induced immunotherapy displays ultrahigh antitumor effects even comparable to that of PDT. On the other hand, PDT toward primary tumors enhances the immunotherapy-caused regression of the irradiation-free distant tumors. Consequently, both the primary and the distant tumors are almost completely eliminated. This tumor-specific immunotherapy-based nanoplatform is potentially expandable to multiple tumor types and readily equipped with diverse functions owing to the flexible nanoparticle options.

Abstract
Biomimetic functionalization of nanoparticles through camouflaging with cellular membranes has emerged as a promising strategy for cancer theragnostics. Cellular membranes used for camouflaging nanoparticles are generally isolated from blood cells, immune cells, cancer cells, and stem cells. The camouflaging strategy of wrapping nanoparticles with cellular membranes allows for superior tumor targeting through self-recognition, homotypic targeting and prolonged systematic circulation, thereby aiding in effective tumor therapy. In this review, we emphasized the various types of cellular membrane-camouflaged nanoparticles, their mechanisms in targeted therapy and various biomimetic strategies for anti-cancer therapy.

Abstract
Cellular-membrane-coated nanoparticles have increasingly been pursued to leverage the natural cell functions for enhancing biocompatibility and improved therapeutic efficacy. Taking advantage of specialized cell membranes or combining functions from different membrane types facilitates the strengthening of their functionality. Herein, we fuse membrane materials derived from red blood cells (RBCs) and melanoma cells (B16-F10 cells) to create a hybrid biomimetic coating (RBC-B16), and RBC-B16 hybrid membrane camouflaged doxorubicin (DOX)-loaded hollow copper sulfide nanoparticles (DCuS@[RBC-B16] NPs) are fabricated for combination therapy of melanoma. The DCuS@[RBC-B16] NPs are comprehensively characterized, showing the inherent properties of the both source cells. Compared to the bare CuS NPs, the DCuS@[RBC-B16] NPs exhibit highly specific self-recognition to the source cell line in vitro and achieve markedly prolonged circulation lifetime and enhanced homogeneous targeting abilities in vivo inherited from the source cells. Thus, the DOX-loaded [RBC-B16]-coated CuS NP platform exhibits excellent synergistic photothermal/chemotherapy with about 100% melanoma tumor growth inhibition rate. The reported strategy may contribute to personalized nanomedicine of various tumors by combining the RBCs with a homotypic cancer membrane accordingly on the surface of the nanoparticle.

Abstract
Selectively cuting off the nutrient supply and the metabolism pathways of cancer cells would be a promising approach to improve the efficiency of cancer treatment. Here, a cancer targeted cascade bioreactor (designated as mCGP) was constructed for synergistic starvation and photodynamic therapy (PDT) by embedding glucose oxidase (GOx) and catalase in the cancer cell membrane-camouflaged porphyrin metal-organic framework (MOF) of PCN-224 (PCN stands for porous coordination network). Due to biomimetic surface functionalization, the immune escape and homotypic targeting behaviors of mCGP would dramatically enhance its cancer targeting and retention abilities. Once internalized by cancer cells, mCGP was found to promote microenvironmental oxygenation by catalyzing the endogenous hydrogen peroxide (H2O2) to produce oxygen (O2), which would subsequently accelerate the decomposition of intracellular glucose and enhance the production of cytotoxic singlet oxygen (1O2) under light irradiation. Consequently, mCGP displayed amplified synergistic therapeutic effects of long-term cancer starvation therapy and robust PDT, which would efficiently inhibit the cancer growth after a single administration. This cascade bioreactor would further facilitate the development of complementary modes for spatiotemporally controlled cancer treatment.

Abstract
Cell-derived nanoparticles have been garnering increased attention due to their ability to mimic many of the natural properties displayed by their source cells. This top-down engineering approach can be applied toward the development of novel therapeutic strategies owing to the unique interactions enabled through the retention of complex antigenic information. Herein, we report on the biological functionalization of polymeric nanoparticles with a layer of membrane coating derived from cancer cells. The resulting core-shell nanostructures, which carry the full array of cancer cell membrane antigens, offer a robust platform with applicability toward multiple modes of anticancer therapy. We demonstrate that by coupling the particles with an immunological adjuvant, the resulting formulation can be used to promote a tumor-specific immune response for use in vaccine applications. Moreover, we show that by taking advantage of the inherent homotypic binding phenomenon frequently observed among tumor cells the membrane functionalization allows for a unique cancer targeting strategy that can be utilized for drug delivery applications.
