Abstract
Drugs that target immune checkpoint have become the most popular weapon in cancer immunotherapy, yet only have practical benefits for a small percentage of patients. Tumor cells constantly interact with their microenvironment, which is made up of a variety of immune cells as well as endothelial cells and fibroblasts. Immune checkpoint expression and blocked signaling of immune cells in the tumor microenvironment (TME) are key to tumor progression. In this study, we perform deliberation convolution on the TCGA database for human lung, breast, and colorectal cancer to infer crosstalk between immune checkpoint receptors (ICRs) and ligands (ICLs) in TME of pan-carcinogenic solid tumor types, validated by flow cytometry. Analysis of immune checkpoints showed that there was little variation between different tumor types. It showed that CD160, LAG3, TIGIT were found to be highly expressed in CD8+ T cells instead of CD4+ T cells, PD-L1, PD-L2, CD86, LGALS9, TNFRSF14, LILRB4 and other ligands were highly expressed on macrophages, FVR, NECTIN2, FGL1 were highly expressed on Epithelial cells, CD200 was highly expressed in Endothelial cells, and CD80 was highly expressed in CD8 High expression on T cells. Overall, our study provides a new resource for the expression of immune checkpoints in TME on various types of cells. Significance: This study provides immune checkpoint expression of immune cells of multiple cancer types to infer immune mechanisms in the tumor microenvironment and provide ideas for the development of new immune checkpoint-blocking drugs.

Eur J Pharm Biopharm 2024; 197:114232. [PMID: 38395176 DOI: 10.1016/j.ejpb.2024.114232] [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: 01/04/2024] [Revised: 02/14/2024] [Accepted: 02/19/2024] [Indexed: 02/25/2024]
Abstract
Tumor associated macrophages (TAMs) are the most abundant immune cell type in the tissue microenvironment, affecting tumor progression, metastasis and therapeutic response. Different macrophage activation ("polarization") states can be distinguished: resting (M0; non-activated), pro-inflammatory/anti-tumorigenic (M1) and anti-inflammatory/pro-tumorigenic (M2). When exploring macrophages as targets in novel cancer immunotherapy approaches, TAM repolarization from the M2 into the M1 phenotype is an intriguing strategy to block their pro-tumoral and enhance their anti-tumoral properties. In the context of RNAi-based gene knockdown of M2 promoting genes, major bottlenecks include cellular siRNA delivery and correct intracellular processing. This is particularly true in case of macrophages as a cell type well-known to be notoriously hard-to-transfect. Among polymeric nanocarriers, the cationic polymer polyethylenimine (PEI) is widely explored for delivering nucleic acids. Further advanced nanocarriers are tyrosine-modified polymers based on PEI or polypropylenimine dendrimers (PPI) for highly efficient siRNA delivery in vitro and in vivo. In this paper, we explored a panel of PEI- or PPI-based nanoparticle systems for siRNA-mediated gene knockdown efficacy in macrophages and subsequent TAM repolarization. The tyrosine-modified linear 10 kDa PEI (LP10Y) or branched 5 kDa PEI (P5Y) as well as a tyrosine-modified PPI (PPI-Y) were found most efficient for gene knockdown in macrophage cell lines or primary macrophages, independent of their polarization. Knockdown of STAT6 or STAT3 led to repolarization of M2 macrophages, as indicated by alterations in various M2 and M1 marker levels. This highly specific approach also demonstrated non-redundant functions of STAT3 and STAT6. Importantly, macrophage re-polarization from M2 to M1 upon PPI-Y/siRNA-mediated STAT6 knockdown increased tumor cell phagocytosis in a co-culture model. In conclusion, we identify certain tyrosine-modified PEI- or PPI-based nanoparticles as particularly efficient for macrophage transfection, and the specific, siRNA-mediated STAT6 knockdown as a promising approach for macrophage repolarization and enhancement of their tumor cell suppressive role.

Abstract
Cancer immunotherapy is a groundbreaking strategy that has revolutionized the field of oncology compared to other therapeutic strategies, such as surgery, chemotherapy, or radiotherapy. However, cancer complexity, tumor heterogeneity, and immune escape have become the main hurdles to the clinical application of immunotherapy. Moreover, conventional immunotherapies cause many harmful side effects owing to hyperreactivity in patients, long treatment durations and expensive cost. Nanotechnology is considered a transformative approach that enhances the potency of immunotherapy by capitalizing on the superior physicochemical properties of nanocarriers, creating highly targeted tissue delivery systems. These advantageous features include a substantial specific surface area, which enhances the interaction with the immune system. In addition, the capability to finely modify surface chemistry enables the achievement of controlled and sustained release properties. These advances have significantly increased the potential of immunotherapy, making it more powerful than ever before. In this review, we introduce recent nanocarriers for application in cancer immunotherapy based on strategies that target different main immune cells, including T cells, dendritic cells, natural killer cells, and tumor-associated macrophages. We also provide an overview of the role and significance of nanotechnology in cancer immunotherapy.

Abstract
INTRODUCTION RNA interference (RNAi) has demonstrated great potential in treating skin-related diseases, as small interfering RNA (siRNA) can efficiently silence specific genes. The design of skin delivery systems for siRNA is important to protect the nucleic acid while facilitating both skin targeting and cellular ingestion. Entrapment of siRNA into nanocarriers can accomplish these aims, contributing to improved targeting, controlled release, and increased transfection. AREAS COVERED The siRNA-based nanotherapeutics for treating skin disorders are summarized. First, the mechanisms of RNAi are presented, followed by the introduction of challenges for skin therapy. Then, the different nanoparticle types used for siRNA skin delivery are described. Subsequently, we introduce the mechanisms of how nanoparticles enhance siRNA skin penetration. Finally, the current investigations associated with nanoparticulate siRNA application in skin disease management are reviewed. EXPERT OPINION The potential application of nanotherapeutic RNAi allows for a novel skin application strategy. Further clinical studies are required to confirm the findings in the cell-based or animal experiments. The capability of large-scale production and reproducibility of nanoparticle products are also critical for translation to commercialization. siRNA delivery by nanocarriers should be optimized to attain cutaneous targeting without the risk of toxicity.

Abstract
Simple Summary Natural killer cells are a part of the native immune response to cancer. NK cell-based immunotherapies are an emerging strategy to kill tumor cells. This paper reviews the role of NK cells, their mechanism of action for killing tumor cells, and the receptors which could serve as potential targets for signaling. In this review, the role of nanoparticles in NK cell activation and increased cytotoxicity of NK cells against cancer are highlighted. Abstract Natural killer (NK) cells are one of the first lines of defense against infections and malignancies. NK cell-based immunotherapies are emerging as an alternative to T cell-based immunotherapies. Preclinical and clinical studies of NK cell-based immunotherapies have given promising results in the past few decades for hematologic malignancies. Despite these achievements, NK cell-based immunotherapies have limitations, such as limited performance/low therapeutic efficiency in solid tumors, the short lifespan of NK cells, limited specificity of adoptive transfer and genetic modification, NK cell rejection by the patient’s immune system, insignificant infiltration of NK cells into the tumor microenvironment (TME), and the expensive nature of the treatment. Nanotechnology could potentially assist with the activation, proliferation, near-real time imaging, and enhancement of NK cell cytotoxic activity by guiding their function, analyzing their performance in near-real time, and improving immunotherapeutic efficiency. This paper reviews the role of NK cells, their mechanism of action in killing tumor cells, and the receptors which could serve as potential targets for signaling. Specifically, we have reviewed five different areas of nanotechnology that could enhance immunotherapy efficiency: nanoparticle-assisted immunomodulation to enhance NK cell activity, nanoparticles enhancing homing of NK cells, nanoparticle delivery of RNAi to enhance NK cell activity, genetic modulation of NK cells based on nanoparticles, and nanoparticle activation of NKG2D, which is the master regulator of all NK cell responses.

Abstract
Graphene oxide (GO) has emerged as a potential drug delivery vector. For siRNA delivery, GO should be modified to endow it with gene delivery ability and targeting effect. However, the cationic materials used previously usually had greater toxicity. In this study, GO was modified with a non-toxicity cationic material (chitosan) and a tumor specific monoclonal antibody (anti-EpCAM) for the delivery of survivin-siRNA (GCE/siRNA). And the vector (GCE) prepared was proved with excellent biosafety and tumor targeting effect. The GCE exhibited superior performance in loading siRNA, maintained stability in different solutions and showed excellent protection effect for survivin-siRNA in vitro. The gene silencing results in vitro showed that the mRNA level and protein level were down-regulated by 48.24% ± 2.50% and 44.12% ± 3.03%, respectively, which was equal with positive control (P > 0.05). It was also demonstrated that GCE/siRNA had a strong antitumor effect in vitro, which was attributed to the efficient antiproliferation, and migration and invasion inhibition effect of GCE/siRNA. The results in vivo indicated that GCE could accumulate siRNA in tumor tissues. The tumor inhibition rate of GCE/siRNA 54.74% ± 5.51% was significantly higher than control 4.87% ± 8.49%. Moreover, GCE/siRNA showed no toxicity for blood and main organs, suggesting that it is a biosafety carrier for gene delivery. Taken together, this study provides a novel design strategy for gene delivery system and siRNA formulation.

Abstract
Cancer immunotherapy has recently emerged as a rising star due to its ability to activate patients' immune systems to fight tumors and prevent relapse. Conversely, the interest in cancer nanomedicine has seemingly waned due to its lackluster clinical translation. Despite being hailed as a game-changer in oncology, cancer immunotherapy still faces numerous challenges. Combining both entities together has thus been one among several solutions proposed to circumvent these challenges. This solution has since gained traction and has also led to a renaissance of cancer nanomedicine. While most combinations are currently experimental at best, some have progressed on to clinical trials. This review thus seeks to examine the advantages and disadvantages of integrating both modalities as a cancer treatment. The opportunities, challenges and future directions of this emerging field will also be explored with the hope that such a combination will lead to a paradigm shift in cancer treatments.

Abstract
Background Breast cancer is the most prevalent cancer among women. Doxorubicin (DOX) is a common chemotherapeutic drug used to treat many different cancers. However, multidrug resistance limits the treatment of breast cancer. MDR1 siRNA (siMDR1) combinatorial therapy has attracted significant attention as a breakthrough therapy for multidrug resistance in tumors. However, naked siRNA is easily degraded by enzymatic hydrolysis requiring an siRNA carrier for its protection. Human serum albumin (HSA) was selected as the carrier due to its excellent biocompatibility, non-toxicity, and non-immunogenicity. Cetuximab was used to modify the HSA nanoparticles in order to target the tumor tissues. Methods This study used a central composite design response surface methodology (CCD-RSM) to investigate the optimal formula for HSA NPs preparation. Cex-HSA/DOX/MDR1 siRNA (C-H/D/M) was characterized by dynamic light scattering and transmission electron microscopy. The efficacy of C-H/D/M tumor growth inhibitory activity was investigated in vitro and in vivo using confocal imaging, MTT assay, and an MCF-7/ADR tumor-bearing mice model. RT–qPCR, ELISA analysis, and flow cytometry were used to investigate the in vitro antitumor mechanisms of C-H/D/M. Results The diameter and PDI of the C-H/D/M were 173.57 ± 1.30 nm and 0.027 ± 0.004, respectively. C-H/D/M promoted and maintained the sustained release and the uptake of DOX significantly. After transfection, the MDR1 mRNA and P-gp expression levels were down-regulated by 44.31 ± 3.6% (P < 0.01) and 38.08 ± 2.4% (P < 0.01) in an MCF-7/ADR cell line. The fluorescent images of the treated BALB/c nude mice revealed that C-H/D/M achieved targeted delivery of siMDR1 and DOX into the tumor tissue. The in vivo tumor inhibition results demonstrated that the tumor inhibition rate of the C-H/D/M treated group was 54.05% ± 1.25%. The biosafety results indicated that C-H/D/M did not induce significant damages to the main organs in vivo. Conclusion C-H/D/M can be used as an ideal non-viral tumor-targeting vector to overcome MDR and enhance the antitumor effect.

Abstract
Efficient capture and presentation of tumor antigens by antigen-presenting cells (APCs), especially dendritic cells (DCs), are crucial for activating the anti-tumor immunity. However, APCs are immunosuppressed in the tumor microenvironment, which hinders the tumor elimination. To reprogram APCs for inducing strong anti-tumor immunity, we report here a co-delivery immunotherapeutic strategy targeting the phagocytosis checkpoint (signal regulatory protein α, SIRPα) and stimulator of interferon genes (STING) of APCs to jointly enhance their ability of capturing and presenting tumor antigens. In brief, a small interfering RNA targeting SIRPα (siSIRPα) and a STING agonist (cGAMP) were co-delivered into APCs by the encapsulation into poly(ethylene glycol)-b-poly(lactide-co-glycolide)-based polymeric nanoparticles (NPsiSIRPα/cGAMP). siSIRPα-mediated SIRPα silence promoted APCs to actively capture tumor antigens by engulfing tumor cells. The cGAMP-stimulated STING signaling pathway further enhanced the functions of APCs, thereby increased the activation and expansion of CD8+ T cells. Using ovalbumin (OVA)-expressing melanoma as a model, we demonstrated that NPsiSIRPα/cGAMP stimulated the activation of OVA-specific CD8+ T cells and induced holistic anti-tumor immune responses by reversing the immunosuppressive phenotype of APCs. Collectively, this co-delivery strategy synergistically enhanced the functions of APCs and can be extended to the treatment of tumors with poor immunogenicity.

Abstract
Cancer immunotherapy is to artificially stimulate the immune system against tumor cells. Effectively increasing the immunogenicity of dying tumor cells has great potential to stimulate the anticancer immune responses. Recently, a synthetic cationic anticancer polypeptide (ACPP) is prepared, which mimics the host defense peptides, to effectively inhibit tumor growth by directly inducing rapid necrosis of cancer cells through a membrane-lytic mechanism. Thus, this ACPP has the potential ability to induce immunogenic cancer cell death (ICD) and promote antitumor immunity. Herein, it is reported that ACPP successfully induces ICD in mouse colon cancer cells, resulting in effectively promoting T-cell-dependent antitumor immune responses by enhanced activation of dendritic cells. Interestingly, the level of natural killer cells, which are another kind of antitumor effector cell, in tumor microenvironment is also significantly increased by ACPP. The ratio of M1/M2 tumor-associated macrophages is further obviously increased, indicating that tumor immunosuppressive microenvironment has been effectively reprogramed. More importantly, it is found that the anticancer immunity induced by ACPP is dose dependent. Finally, 40% of the established CT26 tumors are completely eliminated by ACPP treatment with an optimized dose. This study proposes a simple and effective strategy for promoting cancer immunotherapy.
