Abstract
CpG oligodeoxynucleotides (ODNs) strongly activate the immune system after binding to toll-like receptor 9 (TLR9) in lysosome, which demonstrated significant potential in cancer immunotherapy. However, their therapeutic efficacy is limited by drawbacks such as rapid degradation and poor cellular uptake. Although encouraging progress have been made on developing various delivery systems for CpG ODNs, safety risks of the synthetic nanocarriers as well as the deficient CpG ODNs release within lysosome remain big obstacles. Herein, we developed a novel nanovector for lysosome-targeted CpG ODNs delivery and enhanced cancer immunotherapy. Natural glycogen was simply aminated (NH2-Gly) through grafting with diethylenetriamine (DETA), which was spherical in shape with diameter of approximately 40 nm. NH2-Gly possessed good biocompatibility. Cationic NH2-Gly complexed CpG ODNs well and protected them from nuclease digestion. NH2-Gly significantly enhanced the cellular uptake of CpG ODNs. Efficient CpG ODNs release was observed in the presence of α-glucosidase that mimicking the environment of lysosome. Consequently, NH2-Gly/CpG complexes triggered potent antitumor immunity and effectively inhibit the tumor growth without causing any toxic effect or tissue damages. This work highlights the promise of glycogen for lysosome-targeted on-command delivery of CpG ODNs, which brings new hope for precision cancer immunotherapy.

Abstract
CpG oligodeoxynucleotides (CpG ODNs) activate immune system and show strong potential in cancer immunotherapy. However, therapeutic efficacy of CpG ODNs is hampered due to rapid nuclease degradation and insufficient cellular uptake. Delivery of CpG ODNs into antigen presenting cells (APCs) is vital to enhance their therapeutic efficacy. Herein, we developed a super-convenient yet efficient strategy for macrophage-targeted delivery of CpG ODNs and synergistically enhanced cancer immunotherapy. Aminated yeast β-D-glucan (NH2-Glu) was simply synthesized through functionalization of β-D-glucan with DETA, which exhibited a dendrimer-like shape with size of about 80 nm. NH2-Glu complexed negatively-charged CpG ODNs. The as-prepared NH2-Glu/CpG complexes were positively charged, uniformly dispersed and exhibited good stability against nuclease degradation. Due to the specific recognition with dectin-1 expressed on macrophages, NH2-Glu/CpG complexes targeted macrophage and exhibited significantly enhanced cellular uptake due to dectin-1-mediated endocytosis. NH2-Glu/CpG complexes showed potent immunostimulatory activity. Contributed by the inherent immunostimulatory and antitumor activity, yeast β-D-glucan functioned synergistically with CpG ODNs in inducing antitumor immunity. NH2-Glu/CpG complexes remarkably inhibited tumor growth without causing toxic effect. In summary, this work provides a facile yet efficient macrophage-targeted CpG ODNs delivery system for cancer immunotherapy.

Abstract
The biochemical indicators of tumor microenvironment (TME) that are different from normal tissues provide the possibility for constructing intelligent drug delivery systems (DDSs). Polysaccharides with good biocompatibility, biodegradability, and unique biological properties are ideal materials for constructing DDSs. Nanogels, micelles, organic-inorganic nanocomposites, hydrogels, and microneedles (MNs) are common polysaccharide-based DDSs. Polysaccharide-based DDSs enable precise control of drug delivery and release processes by incorporating TME-specific biochemical indicators. The classification and design strategies of polysaccharide-based TME-responsive DDSs are comprehensively reviewed. The advantages and challenges of current polysaccharide-based DDSs are summarized and the future directions of development are foreseen. The polysaccharide-based TME-responsive DDSs are expected to provide new strategies and solutions for cancer therapy and make important contributions to the realization of precision medicine.

Abstract
Immunostimulatory CpG oligodeoxynucleotides (CpG ODNs) show strong potential in cancer immunotherapy. However, therapeutic efficacy of CpG ODNs is hindered due to rapid nuclease degradation and insufficient cellular uptake. Transfecting CpG ODNs into antigen presenting cells (APCs) is vital to enhance their therapeutic efficacy while reduce the potential side effects. Herein, a multifunctional CpG ODNs vector was fabricated through functionalization of graphene oxide (GO) with yeast β-D-glucan, and its potential in cancer immunotherapy was further investigated. GO-β-D-glucan protected CpG ODNs from nuclease digestion. β-D-glucan endowed the delivery system with targeting ability for macrophage due to its recognition with dectin-1. Thus, GO-β-D-glucan enhanced the delivery of CpG ODNs into RAW264.7 cells due to dectin-1-mediated endocytosis. More importantly, β-D-glucan functioned synergistically with CpG ODNs in inducing antitumor immunity. GO-β-D-glucan/CpG ODNs inhibited the tumor cells growth more effectively. This work provides a macrophage-targeted CpG ODNs delivery system for cancer immunotherapy. Graphic abstract.

Abstract
The cancer immunotherapeutic effect of a carboxymethylated β-d-glucan (CMPTR)/iron oxide nanoparticles (IONPs) system (CMPTR/IONPs) were investigated by using cell culture of bone marrow-derived macrophages (BMDMs) and B16F10 melanoma skin cancer-bearing mouse model. When compared with that of control group, CMPTR/IONPs-treated M2-like BMDMs exhibited upregulated M1 biomarkers expression, significantly inhibited the migration of B16F10 cancer cells (p < 0.05), and had the highest apoptotic percentage of B16F10 cancer cells (80.39 ± 8.73 %) in co-culture system. Intratumoral administration of CMPTR/IONPs significantly (p < 0.05) suppressed tumor growth (46.58 % based on tumor weight) in mice and enhanced the M1/M2 ratio from 0.40 ± 0.09 (control group) to 6.64 ± 1.61 in tumor associated macrophages (TAMs) which was higher than that of in CMPTR (1.27 ± 0.38), IONPs (1.38 ± 0.17). CMPTR/IONPs treatment also promoted apoptosis in cancer cells and increased the infiltration of CD4 and CD8 T-lymphocytes in tumor tissues. These results could be due to the combined effects of CMPTR and IONPs in the CMPTR/IONPs system, possibly mediated by the activation of NF-κB and IRF5 pathways for inducing M1 macrophages polarization and had potential cancer immunotherapeutic applications.

Abstract
Photodynamic therapy occupies an important position in cancer therapy because of its minimal invasiveness and high spatiotemporal precision, and photodynamic/gene combined therapy is a promising strategy for additive therapeutic effects. However, the asynchronism and heterogeneity between traditional chemical photosensitizers and nucleic acid would restrict the feasibility of this strategy. KillerRed protein, as an endogenous photosensitizer, could be directly expressed and take effect in situ by transfecting KillerRed reporter genes into cells. Herein, a simple and easily prepared sodium alginate (SA)-doping cationic nanoparticle SA@GP/DNA was developed for dual gene delivery. The nanoparticles could be formed through electrostatic interaction among sodium alginate, polycation, and plasmid DNA. The title complex SA@GP/DNA showed good biocompatibility and gene transfection efficiency. Mechanism studies revealed that SA doping could facilitate the cellular uptake and DNA release. Furthermore, SA@GP/DNA was applied to the codelivery of p53 and KillerRed reporter genes for the synergistic effect combining p53-mediated apoptosis therapy and KillerRed-mediated photodynamic therapy. The ROS generation, tumor cell growth inhibition, and apoptosis assays proved that the dual-gene transfection could mediate the better effect compared with single therapy. This rationally designed dual gene codelivery nanoparticle provides an effective and promising platform for genetically bimodal therapy.

Abstract
β-d-glucans have the potential of serving as both macrophage-targeted carriers and immune stimulators via inducing trained immunity in macrophages. In this study, a carboxymethylated β-glucan from mushroom sclerotium of Pleurotus tuber-regium (CMPTR) was combined with iron oxide nanoparticles (IONPs) to form nanocomplexes (CMPTR/IONPs) with particle size around 193 ± 7 nm, which could exert a concerted effect on inducing proinflammatory M1 phenotype macrophages for immunotherapy. This nanocomplex exhibited good stability and low cytotoxicity (over 80% cellular viability of RAW 264.7 and THP-1) and higher cellular uptake by murine macrophages compared with B16F10 cells (p < 0.05). CMPTR/IONPs could convert M2-like bone marrow-derived macrophages into M1 phenotypes with upregulated expression of pro-inflammatory cytokines (IL12 and TNF-α, p < 0.05) and reduced immune-suppressive cytokines (IL10 and TGF-β, p < 0.05). Such polarization was mediated by the combined signaling regulatory factors, including IONP-stimulated IRF5 and CMPTR-triggered TLRs-NF-κB pathways (p < 0.05). Accordingly, CMPTR could have a dual function as a macrophage-targeting carrier for IONPs and an immunostimulant to induce inflammatory M1 macrophage polarization for immunotherapy.

Abstract
Curdlan is an exopolysaccharide, which is composed of glucose linked with β-(1,3)-glycosidic bond and is produced by bacteria, such as Alcaligenes spp., Agrobacterium spp., Paenibacillus spp., Rhizobium spp., Saccharomyces cerevisiae, Candida spp., and fungal sources like Aureobasidium pullulan, Poria cocos, etc. Curdlan has been utilized in the food and pharmaceutical industries for its prebiotic, viscosifying, and water-holding properties for decades. Recently, the usefulness of curdlan has been further explored by the pharmaceutical industry for its potential therapeutic applications. Curdlan has exhibited immunoregulatory and antitumor activity in preclinical settings. It was observed that curdlan can prevent the proliferation of malarial merozoites in vivo; therefore, it may be considered as a promising therapy for the treatment of end-stage malaria. In addition, curdlan has demonstrated potent antiviral effects against human immunodeficiency virus (HIV) and Aedes aegypti virus. It has been suggested that the virucidal properties of curdlans should be extended further for other deadly viruses, such as severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the current severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2/COVID-19). The prebiotic property of curdlan would confer beneficial effects on the host by promoting the growth of healthy microbiota in the gut and consequently help to reduce gastrointestinal disorders. Therefore, curdlan can be employed in the manufacture of prebiotics for the management of various gastrointestinal dysbiosis problems. Studies on the mechanism of action of curdlan-induced suppression in microbial and tumor cells at the cellular and molecular levels would not only enhance our understanding regarding the therapeutic effectiveness of curdlan but also help in the discovery of new drugs and dietary supplements. The primary focus of this review is to highlight the therapeutic interventions of curdlan as an anticancer, anti-malaria, antiviral, and antibacterial agent in humans. In addition, our review provides the latest information about the chemistry and biosynthesis of curdlan and its applications for making novel dairy products, functional foods, and nutraceuticals and also details about the recent patents of curdlan and its derivatives.

Abstract
Vaccines, in many cases, stimulate only too weak immunogenicity to prevent infection. Therefore, adjuvants are required during their preparation to boost the immune response. We herein developed a PEGylated nano-adjuvant based on Rehmannia glutinosa polysaccharide (RGP). The addition of PEG layer exhibits enhanced immune performance of the nano-RGP. Stimulation of dendritic cells (DCs) with PEGylated nano-RGP (pRL) led to increased proliferation and cytokine production (IL-6, IL-12, IL-1β and TNF-α). The pRL was internalized into DCs via a rapid and efficient method. The mice immunized with pRL exhibited enhanced antigen-specific serum IgG and Th1-(IFN-γ), Th2-(IL-4), and Th17-(IL-17, IL-6) cytokine production, contributing to a good anti-infection performance. Furthermore, the pRL could effectively deliver the antigen to the lymph nodes (LNs), activate DC in the LN and produce enhanced CD4+and CD8+ T-cells-derived memory (CD44high CD62Lhigh), and effector (CD44high CD62Llow) as well as functional phenotypes. Our results revealed that pRL can act as a promising adjuvant with targeted delivery of antigen due to its effective activation and robust adaptive immunity induction of DCs.

Abstract
Use of polysaccharides as carriers in drug delivery system is a hot topic, especially those with specific recognition of immune cells, enabling them to be applied in targeting delivery system. β-d-glucans are naturally occurring non-digestible polysaccharides with immunomodulatory activities that have attracted increasing attention to serve as therapeutic agents or immune-adjuvants. Being able to be specifically recognized by immune cells like macrophages, β-d-glucans can be developed as promising carriers for targeting delivery with stability, biocompatibility and specificity when applied in immunotherapy. Targeting tumor associated macrophages (TAMs) is an emerging strategy for cancer immunotherapy since it exerts anti-cancer effects based on modulating body immunity in tumor microenvironment (TME). This new strategy does not require high concentration of drugs to kill cancer cells directly and lessen tumor recurrence by creating unique immune memory for malignant cells. In this review, construction strategies of polysaccharide-based drug delivery system of three types of β-d-glucan including non-yeast and yeast β-d-glucans as well as hyper-branched β-d-glucan are discussed with reference to their branching characteristics and conformation. The applications of these β-d-glucans as nano-carrier for drug delivery targeting TAMs are also discussed.
