Abstract
We have previously demonstrated that administration of oligomannose-coated liposomes (OMLs), in which an antigen is encased, induce antigen-specific Th1 immune responses and CTLs. In the present study, we showed that TLR4 signaling is required for the induction of specific immune responses following OML administration. In C3H/HeJ mice, which express a dysfunctional TLR4, the antigen-specific Th1 immune response could not be elicited following intraperitoneal administration of OVA-encased OMLs (OML/OVA). However, OML uptake by peritoneal cells, the subsequent production of IL-12 and the upregulation of co-stimulatory molecules and MHC class II on the cells in response to OML uptake occurred in C3H/HeJ mice to the same extent as in wild type C3H/HeN mice. In addition, peritoneal phagocytic cells from TLR4(-/-) mice that ingest OML/OVA can activate CD4(+) T cells from OT-II mice. On the other hand, the number of OML-ingesting peritoneal cells that migrated into mesenteric lymph nodes in C3H/HeJ mice was significantly less than that in C3H/HeN mice. Therefore, the chemotactic capability of OML-ingesting peritoneal phagocytes to the draining lymph nodes rather than the activation and maturation of the cells in response to OML uptake is impaired by lack of TLR4 signaling, and disorder of the Th1 immune response elicited by OMLs in mice, which lack TLR4 signaling, is due to the impairment of cell migration following OML uptake.

Abstract
A hepatic tumor bitargeted microemulsions drug delivery system using coix seed oil and coix seed polysaccharide (CP) acting as anticancer components, as well as functional excipients, was developed for enhanced tumor-specific accumulation by CP-mediated enhancement on passive tumor targeting and modification of galactose stearate (tumor-targeted ligand). In the physicochemical characteristics studies, galactose stearate-modified coix seed multicomponent microemulsions containing 30% CP (w%) (Gal-C-MEs) had a well-defined spherical shape with a small size (47.63 ± 1.41 nm), a narrow polydispersity index (PDI, 0.101 ± 0.002), and a nearly neutral surface charge (-4.37 ± 1.76 mV). The half-maximal inhibitory concentration (IC50) of Gal-C-MEs against HepG2 cells was 70.2 μg/mL, which decreased by 1.8-fold in comparison with that of coix seed multicomponent microemulsions (C-MEs). The fluorescence intensity of fluorescein isothiocyanate (FITC)-loaded Gal-C-MEs (FITC-Gal-C-MEs) internalized by HepG2 cells was 1.8-fold higher than that of FITC-loaded C-MEs (FIT C-C-MEs), but the cellular uptake of the latter became reduce by 1.6-fold when the weight ratio of CP decreased up to 10%. In the cell apoptosis studies, C-MEs (containing 30% CP) did not show a significant difference with Gal-C-MEs, but exhibited 3.3-fold and 1.5-fold increase relative to C-MEs containing 10% CP and 20% CP, respectively. In the in vivo tumor targeting studies, Cy5-loaded Gal-C-MEs (Cy5-Gal-C-MEs), notably distributed in the tumor sites and still found even at 48 h post-administration, displayed the strongest capability of tumor tissue accumulation and retention among all the test groups. Most importantly, Gal-C-MEs had stronger inhibition of tumor growth, prolonged survival time and more effectively tumor cell apoptosis induction in comparison with C-MEs containing different amounts of CP, which further confirmed that a certain amount of CP and tumor-targeted ligand were of great importance to potent anticancer efficacy. The aforementioned results suggested that Gal-C-MEs presented promising potential as a highly effective and safe anticancer drug delivery system for enhanced liver cancer delivery.

Abstract
The present investigation reports the preparation, optimization, and characterization of surface engineered solid lipid nanoparticles (SLNs) encapsulated with doxorubicin (DOX). Salient features such as biocompatibility, controlled release, target competency, potential of penetration, improved physical stability, low cost and ease of scaling-up make SLNs viable alternative to liposomes for effective drug delivery. Galactosylation of SLNs instructs some gratifying characteristic, which leads to the evolution of promising delivery vehicles. The impendence of lectin receptors on different cell surfaces makes the galactosylated carriers admirable for targeted delivery of drugs to ameliorate their therapeutic index. Active participation of some lectin receptors in immune responses to antigen overlaid the application of galactosylated carriers in delivery of antigen and immunotherapy for treatment of maladies like cancer. These advantages revealed the promising potential of galactosylated carriers in each perspective of drug delivery. The developed DOX loaded galactosylated SLNs formulation was found to have particle size 239 ± 2.40 nm, PDI 0.307 ± 0.004, entrapment efficiency 72.3 ± 0.9%. Higher cellular uptake, cytotoxicity, and nuclear localization of galactosylated SLNs against A549 cells revealed higher efficiency of the formulation. In a nutshell, the galactosylation strategy with SLNs could be a promising approach in improving the delivery of DOX for cancer therapy.

Abstract
Background The design and development of an effective malaria vaccine against the pre-erythrocytic and erythrocytic-stages of infection present a great challenge. Methods In the present study, protective efficacy of oligomannose-coated liposome (OML)-entrapped merozoite and sporozoite antigens against Plasmodium berghei challenge infection in BALB/c mice was evaluated. Results Subcutaneous immunization with truncated merozoite surface protein 1 entrapped with OML (OML-PbMSP1) prolonged survival, but failed to protect the mice from erythrocytic-stage infection, despite the antigen-specific antibody responses induced by the immunization regimen. In contrast, immunization with circumsporozoite protein entrapped with OML (OML-PbCSP) elicited antigen-specific humoral and cellular responses, which correlated with substantial protection against sporozoite challenge infections. Conclusions The current results represent the use of an oligomannose-coated liposome-based vaccine against pre-erythrocytic and erythrocytic stages malaria infection. This approach may offer a new vaccination strategy against malaria infection.

Comparison of the carbohydrate preference of SIGNR1 as a phagocytic receptor with the preference as an adhesion molecule. Int Immunopharmacol 2014; 19:27-36.

Abstract
C-type lectin receptors expressed on cell surfaces of antigen-presenting cells can serve as not only cell adhesion molecules but also as phagocytic receptors, and therefore, are potentially useful for antigen targeting for vaccination. In the present study, we compared the carbohydrate preference of the C-type lectin SIGNR1 as a cell adhesion molecule with that of SIGNR1 as a phagocytic receptor, using a series of neoglycolipids (NGLs) and the mouse macrophage-like cells stably expressing SIGNR1. When SIGNR1-mediated cell adhesion was assessed based on the binding of the cells to NGL-coated solid phases, the order of degree of cell adhesion was Le(b)-≈Le(a)-≈Le(x)-≥Man5->Man3-≥α1-3Man2->α1-6Man2-DPPE. By contrast, when SIGNR1-mediated phagocytosis was assessed based on the uptake of NGL-coated liposomes, the order of phagocytosis of the liposomes by the cells was Le(a)-≈Man3->Man5-≈α1-3Man2->Le(x)->Le(b)->α1-6Man2-DPPE. Collectively, SIGNR1 mediates cell adhesion to Lewis blood group antigen-containing NGL-coated solid phases more preferably than those coated with terminal mannose-containing NGLs, but mediates the phagocytosis of the Man3-DPPE- and Le(a)-DPPE-coated liposomes most preferably among the tested NGLs. Thus, the subtle carbohydrate preference of SIGNR1 on the cell surface is altered depending on the function, and the preferable carbohydrate for phagocytosis elucidated using NGL-coated liposomes might be used as the appropriate targeting signals for antigen delivery.

Abstract
Professional phagocytic cells, such as dendritic cells, are mainly responsible for phagocytosis, antigen presentation, and cytokine secretion, which induce subsequent activation of T cell-mediated immunity. Thus, strategies that deliver antigens and stimulatory signals to the cells have significant implications for vaccine design. In this paper, we summarize the potential for liposomes coated with the neoglycolipids containing oligomannose residues (OMLs) as a novel adjuvant for induction of Th1 immune responses and CTLs specific for the encased antigen. OMLs preferentially take up peripheral phagocytic cells. In response to OML uptake, the cells secrete IL-12 selectively, enhance the expression of costimulatory molecules, and migrate into lymphoid tissues from peripheral tissues. OMLs also have the ability to deliver encapsulated protein antigens to the MHC class I and class II pathways to generate antigen-specific CTLs and Th1 cells, respectively, and lipid antigen to CD1d to activate NKT cells. Since administration of OML-based vaccines can eliminate an established tumor, inhibit elevation of the serum IgE level, and prevent progression of protozoan infections in several murine, human, and bovine models, OML-based vaccines have revealed their potential for clinical use in vaccination for a variety of diseases in which CTLs and/or Th1 cells act as effector cells.

Abstract
BACKGROUND Allergen-specific immunotherapy has been anticipated to be a disease-modifying therapy for food allergies. We previously reported that CD8(+) regulatory T cells may prevent antigen-sensitized mice from developing allergic diarrhea. Because oligomannose-coated liposomes (OML) have been shown to induce MHC class I-restricted CD8(+) T cell responses, we analyzed the adjuvant activities of OML for inducing regulatory CD8(+) T cells and mucosal tolerogenic responses in allergen-sensitized mice. METHODS The BALB/c mice that were previously sensitized to ovalbumin (OVA) were intranasally immunized with OVA-encased in OML (OVA-OML) or OVA-encased in non-coated liposomes (OVA-NL). We assessed allergic diarrhea induced by oral OVA administration, OVA-specific immunoglobulin production, and cytokine production in the intestines and mesenteric lymph nodes (MLNs). RESULTS Intranasal immunization with OVA-OML, but not OVA-NL, suppressed the development of allergic diarrhea. This was associated with in vitro Ag-induced IL-10 production and the in vivo expansion of CD8(+) CD28(-) and CD4(+) CD25(+) Foxp3(+) T cell populations among mesenteric lymph node mononuclear cells, and was significantly ablated by anti-SIGNR1 or anti-CR3 mAbs. Up-regulation of serum OVA-specific IgE was suppressed, whereas OVA-specific IgG1, IgG2a, and soluble IgA production were enhanced by intranasal administration of OVA-OML. Adoptive transfer of CD8(+) CD28(-) T cells but not CD28(+) CD8(+) T cells from the MLNs of OVA-OML-treated mice ameliorated the development of diarrhea. CONCLUSION These results suggest that intranasal immunization with Ag-encased OML may be an effective immunotherapy for food allergies, as it induces a subset of regulatory CD8(+) T cells as well as CD4(+) CD25(+) Foxp3(+) T cell and modulates humoral immune responses in allergen-sensitized mice.

Abstract
Gene knock-out of C-type lectin receptors expressed in dendritic cells induced significant alteration of serum N-glycans compared with that of gender-matched controls. Glycotyping analysis suggested that putative-core fucosylation is strongly influenced by differences in the dominant mechanisms after carbohydrate recognition by pattern-recognition receptors, endocytosis of ligands, or induction of cytokines/chemokines. However, the loss of galectin-9, a ligand for T-helper type 1-specific cell-surface molecule, did not affect most N-glycan profiles. Interestingly, lack of the Chst3 gene (chondroitin 6-sulfotransferase) appeared to influence markedly the expression of most N-glycans, especially highly modified glycoforms bearing multiple Neu5Gc, Fuc, and LacNAc units. In contrast, genetic mutations in B4galnt1 and B4galnt2 (GalNAc transferase, responsible for the synthesis of many gangliosides) induced no discernable alteration. These results indicate that the biosynthesis of N-glycans of serum glycoproteins can be affected not only by direct genetic mutations in the glycosyltransferases but also by changes in metabolite availability in sugar nucleotide synthesis and Golgi N-glycosylation pathways caused concertedly in whole cells, tissues, and organs by milder deficiencies in immune cell-surface lectins. Many common chronic conditions, such as autoimmunity, metabolic syndrome, and aging/dementia result.

Abstract
In the immune system, C-type lectins and CTLDs have been shown to act both as adhesion and as pathogen recognition receptors. The Dendritic cell-specific ICAM-3 grabbing non-integrin (DC-SIGN) and its homologs in human and mouse represent an important C-type lectin family. DC-SIGN contains a lectin domain that recognizes in a Ca2+-dependent manner carbohydrates such as mannose-containing structures present on glycoproteins such as ICAM-2 and ICAM-3. DC-SIGN is a prototype C-type lectin organized in microdomains, which have their role as pathogen recognition receptors in sensing microbes. Although the integrin LFA-1 is a counter-receptor for both ICAM-2 and ICAM-3 on DC, DC-SIGN is the high affinity adhesion receptor for ICAM-2/-3. While cell–cell contact is a primary function of selectins, collectins are specialized in recognition of pathogens. Interestingly, DC-SIGN is a cell adhesion receptor as well as a pathogen recognition receptor. As adhesion receptor, DC-SIGN mediates the contact between dendritic cells (DCs) and T lymphocytes, by binding to ICAM-3, and mediates rolling of DCs on endothelium, by interacting with ICAM-2. As pathogen receptor, DC-SIGN recognizes a variety of microorganisms, including viruses, bacteria, fungi and several parasites (Cambi et al. 2005). The natural ligands of DC-SIGN consist of mannose oligosaccharides or fucose-containing Lewis-type determinants. In this chapter, we shall focus on the structure and functions of DC-SIGN and related CTLDs in the recognition of pathogens, the molecular and structural determinants that regulate the interaction with pathogen-associated molecular patterns. The heterogeneity of carbohydrate residues exposed on cellular proteins and pathogens regulates specific binding of DC-expressed C-type lectins that contribute to the diversity of immune responses created by DCs (van Kooyk et al. 2003a; Cambi et al. 2005).

Abstract
In this study, we investigate the potential of peritoneal macrophages to differentiate into dendritic cell (DCs) in response to preferential uptake of oligomannose-coated liposomes (OMLs). About 30% of peritoneal cells (PECs) preferentially took up OMLs that were administered into the peritoneal cavity. The OML-ingesting cells expressed CD11b and F4/80, but lacked CD11c expression, indicating that the OML-ingesting PECs with a CD11b(high)CD11c(-) phenotype are resident peritoneal macrophages. During in vitro cultivation, CD11c(+) cells arose among the PECs with ingested OMLs. CD11c(+) cells also developed among enriched peritoneal CD11b(high)CD11(-) cells from OML-treated mice, and the resulting CD11c(+) cells expressed co-stimulatory molecules and MHC class II. In addition, OML-ingesting CD11b(high)CD11c(+) cells were found in spleen after the enriched peritoneal macrophages with ingested OMLs were transplanted in the peritoneal cavity of mice. These results show that a fraction of peritoneal macrophages can differentiate into mature DCs following uptake of OMLs.

Abstract
In previous studies, we have shown that oligomannose-coated liposomes (OMLs) have a strong adjuvant effect in inducing T-helper 1 (Th1) immune responses and cytotoxic T cells specific for the encased antigen. In the present study, we demonstrate that preferential uptake of OMLs by DCs and subsequent DC maturation and splenic trafficking may be correlated with the adjuvant effect of OMLs. About 3% of resting murine peritoneal cells are CD11b(dull)CD11c(+) cells, which express MHC class II and CD86, and about 30% are CD11b(high)CD11c(-) cells, which express F4/80 and CD14. This indicates that these cells are resident peritoneal DCs and monocytes/macrophages, respectively. Both types of cells rapidly took up OMLs in the peritoneal cavity, but only CD11b(dull)CD11c(+) cells produced interleukin (IL)-12 in response to OML uptake. IL-6 was not produced by either type of cells. The expression levels of CD205 and CCR7, which are markers of cell maturity in murine DCs, were upregulated in CD11b(dull)CD11c(+) cells obtained from OML-treated mice. In addition, CD11b(dull)CD11c(+) cells with ingested OMLs were found in the spleen 18 h after intraperitoneal administration of OMLs. These results indicate that OMLs can be used as a vehicle for delivery of antigens to DCs and as an adjuvant to promote DC maturation, activation, and trafficking into lymphoid organs, thereby eliciting a Th1 immune response.

Abstract
As the role of monocytes and macrophages in a range of diseases is better understood, strategies to target these cell types are of growing importance both scientifically and therapeutically. As particulate carriers, liposomes naturally target cells of the mononuclear phagocytic system (MPS), particularly macrophages. Loading drugs into liposomes can therefore offer an efficient means of drug targeting to MPS cells. Physicochemical properties including size, charge and lipid composition can have a very significant effect on the efficiency with which liposomes target MPS cells. MPS cells express a range of receptors including scavenger receptors, integrins, mannose receptors and Fc-receptors that can be targeted by the addition of ligands to liposome surfaces. These ligands include peptides, antibodies and lectins and have the advantages of increasing target specificity and avoiding the need for cationic lipids to trigger intracellular delivery. The goal for targeting monocytes/macrophages using liposomes includes not only drug delivery but also potentially a role in cell ablation and cell activation for the treatment of conditions including cancer, atherosclerosis, HIV, and chronic inflammation.

Abstract
DC-SIGN is a member of the C-type lectin family. Mainly expressed by myeloid DCs, it is involved in the capture and internalization of pathogens, including human CMV. Several transcripts have been identified, some of which code for putative soluble proteins. However, little is known about the regulation and the functional properties of such putative sDC-SIGN variants. To better understand how sDC-SIGN could be involved in CMV infection, we set out to characterize biochemical and functional properties of rDC-SIGN as well as naturally occurring sDC-SIGN. We first developed a specific, quantitative ELISA and then used it to detect the presence sDC-SIGN in in vitro-generated DC culture supernatants as cell-free secreted tetramers. Next, in correlation with their inflammatory status, we demonstrated the presence of sDC-SIGN in several human body fluids, including serum, joint fluids, and BALs. CMV infection of human tissues was also shown to promote sDC-SIGN release. Based on the analysis of the cytokine/chemokine content of sDC-SIGN culture supernatants, we identified IFN-γ and CXCL8/IL-8 as inducers of sDC-SIGN production by MoDC. Finally, we demonstrated that sDC-SIGN was able to interact with CMV gB under native conditions, leading to a significant increase in MoDC CMV infection. Overall, our results confirm that sDC-SIGN, like its well-known, counterpart mDC-SIGN, may play a pivotal role in CMV-mediated pathogenesis.

Abstract
Defective efferocytosis may perpetuate inflammation in smokers with or without chronic obstructive pulmonary disease (COPD). Macrophages may phenotypically polarize to classically activated M1 (proinflammatory; regulation of antigen presentation) or alternatively activated M2 (poor antigen presentation; improved efferocytosis) markers. In bronchoalveolar lavage (BAL)-derived macrophages from control subjects and smoker/ex-smoker COPD subjects, we investigated M1 markers (antigen-presenting major histocompatibility complex [MHC] Classes I and II), complement receptors (CRs), the high-affinity Fc receptor involved with immunoglobulin binding for phagocytosis (Fc-gamma receptor, FcγR1), M2 markers (dendritic cell-specific intercellular adhesion molecule-grabbing nonintegrin [DC-SIGN] and arginase), and macrophage function (efferocytosis and proinflammatory cytokine production in response to LPS). The availability of glutathione (GSH) in BAL was assessed, because GSH is essential for both M1 function and efferocytosis. We used a murine model to investigate macrophage phenotype/function further in response to cigarette smoke. In lung tissue (disaggregated) and BAL, we investigated CRs, the available GSH, arginase, and efferocytosis. We further investigated the therapeutic effects of an oral administration of a GSH precursor, cysteine l-2-oxothiazolidine-4-carboxylic acid (procysteine). Significantly decreased efferocytosis, available GSH, and M1 antigen-presenting molecules were evident in both COPD groups, with increased DC-SIGN and production of proinflammatory cytokines. Increased CR-3 was evident in the current-smoker COPD group. In smoke-exposed mice, we found decreased efferocytosis (BAL and tissue) and available GSH, and increased arginase, CR-3, and CR-4. Treatment with procysteine significantly increased GSH, efferocytosis (BAL: control group, 26.2%; smoke-exposed group, 17.66%; procysteine + smoke-exposed group, 27.8%; tissue: control group, 35.9%; smoke-exposed group, 21.6%; procysteine + smoke-exposed group, 34.5%), and decreased CR-4 in lung tissue. Macrophages in COPD are of a mixed phenotype and function. The increased efferocytosis and availability of GSH in response to procysteine indicates that this treatment may be useful as adjunct therapy for improving macrophage function in COPD and in susceptible smokers.

Abstract
Both tumor-specific CD4+ and CD8+ T cells have been identified, and the latter is known as a major effector of adaptive antitumor immune responses. Optimal antitumor immune responses are considered to require the concomitant activation of both CD8+ and CD4+ T cells and the additional selective activation of CD4+ T cells with helper, but not regulatory function. As optimal antitumor immune responses are generated by the concomitant activation of both T cell types, it is necessary for vaccine methods involving cytotoxic T-lymphocytes (CTLs) generation to possess a mechanism whereby antigen presenting cells can present administrated exogenous antigens on not only Major histocompatibility complex (MHC) class II, but also MHC class I molecules.

Abstract
In the present study, we investigated the effectiveness of liposomes coated with a neoglycolipid consisting of mannotriose and dipalmitoylphosphatidylcholine (Man3-DPPE) as an adjuvant for induction of mucosal immunity. Immunization of BALB/c mice with ovalbumin (OVA)-encapsulated Man3-DPPE-coated liposomes (oligomannose-coated liposomes; OMLs) by a nasal route produced high levels of OVA-specific IgG and IgA antibodies in serum of immunized mice 1 week after the last nasal immunization, whereas no significant serum antibody responses were observed in mice that received OVA in uncoated liposomes or OVA alone. Seven weeks after the last nasal immunization, nasal challenge with an excess amount of OVA in mice that had received OVA/OMLs led to an anamnestic response to the antigen that resulted in 5- to 10-fold increases of antigen-specific serum IgG and IgA antibodies. Only mice immunized nasally with OML/OVA secreted antigen-specific secretory IgA in nasal washes and produced interferon-gamma secreting cells in nasopharyngeal-associated lymphoreticular tissue. Taken together, these results show that nasal administration of OMLs induces mucosal and systemic immunity that are specific for the entrapped antigen in the liposomes. Thus, liposomes coated with synthetic neoglycolipids might be useful as adjuvants for induction of mucosal immunity.

Abstract
The present study demonstrates that the subcutaneous administration of Neospora caninum dense granule protein 7 (NcGRA7) entrapped in liposomes coated with mannotriose strongly induces the parasite-specific T-helper type 1 immune response and humoral antibody in mice. Although anti-NcGRA7 immunoglobulin G1 antibody production was induced in mice injected with NcGRA7 alone, the dams and offspring were never protected from N. caninum infection. The immunization of mice with liposome-entrapped NcGRA7 before pregnancy resulted in increased offspring survival and decreased the infection rates in the brains of dams after parasite infection at 6 to 9 days of gestation. In conclusion, oligomannose-coated liposome-entrapped NcGRA7 can be used as a new type of effective vaccine to control neosporosis.
