Abstract
Candida albicans is a commensal microorganism in the human gut but occasionally causes invasive C. albicans infection (ICA), especially in immunocompromised individuals. Early initiation of antifungal therapy is associated with reduced mortality of ICA, but rapid diagnosis remains a challenge. The ICA-associated changes in the gut microbiota can be used as diagnostic and therapeutic targets but have been poorly investigated. In this study, we utilized an immunodeficient Rag2γc (Rag2-/-il2γc-/-) mouse model to investigate the gut microbiota alterations caused by C. albicans throughout its cycle, from its introduction into the gastrointestinal tract to invasion, in the absence of antibiotics. We observed a significant increase in the abundance of Firmicutes, particularly Lachnospiraceae and Ruminococcaceae, as well as a significant decrease in the abundance of Candidatus Arthromitus in mice exposed to either the wild-type SC5314 strain or the filamentation-defective mutant (cph1/cph1 efg1/efg1) HLC54 strain of C. albicans. However, only the SC5314-infected mice developed ICA. A linear discriminate analysis of the temporal changes in the gut bacterial composition revealed Bacteroides vulgatus as a discriminative biomarker associated with SC5314-infected mice with ICA. Additionally, a positive correlation between the B. vulgatus abundance and fungal load was found, and the negative correlation between the Candidatus Arthromitus abundance and fungal load after exposure to C. albicans suggested that C. albicans might affect the differentiation of intestinal Th17 cells. Our findings reveal the influence of pathogenic C. albicans on the gut microbiota and identify the abundance of B. vulgatus as a microbiota signature associated with ICA in an immunodeficient mouse model.

Macrophage-reprogramming upconverting nanoparticles for enhanced TAM-mediated antitumor therapy of hypoxic breast cancer. J Control Release 2023; 360:482-495. [PMID: 37423526 DOI: 10.1016/j.jconrel.2023.07.009] [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: 02/26/2023] [Revised: 06/10/2023] [Accepted: 07/06/2023] [Indexed: 07/11/2023]
Abstract
In an attempt to achieve antitumor effects by switching the phenotype of macrophages from the tumor-promoting M2 type to the tumor-suppressing M1 type, we fabricated mannose-decorated/macrophage membrane-coated, silica-layered NaErF4@NaLuF4 upconverting nanoparticles (UCNPs) co-doped with perfluorocarbon (PFC)/chlorin e6 (Ce6) and loaded with paclitaxel (PTX) (UCNP@mSiO2-PFC/Ce6@RAW-Man/PTX: ∼61 nm; -11.6 mV). These nanoparticles were designed to have two major functionalities, (i) efficient singlet oxygen generation aided by an oxygen supply and (ii) good targeting to tumor-associated macrophage (TAMs) (M2-type), to induce polarization to M1 type macrophages that release proinflammatory cytokines and suppress breast cancers. The primary UCNPs consisted of lanthanide elements (erbium and lutetium) in a core@shell structure, and they facilely emitted 660 nm light in response to a deep-penetrating 808 nm near-infrared laser. Moreover, the UCNPs@mSiO2-PFC/Ce6@RAW-Man/PTX were able to release O2 and generate 1O2 because of the co-doped PFC/Ce6 and upconversion. Our nanocarriers' excellent uptake to RAW 264.7 macrophage cells (M2 type) and efficient M1-type polarization activity were clearly demonstrated using qRT-PCR and immunofluorescence-based confocal laser scanning microscopy. Our nanocarriers displayed significant cytotoxicity to 4T1 cells in 2D culture and 3D co-culture systems of 4T1/RAW 264.7 cells. More importantly, UCNPs@mSiO2-PFC/Ce6@RAW-Man/PTX (+808 nm laser) noticeably suppressed tumor growth in 4T1-xenografted mice, compared with the other treatment groups (332.4 vs. 709.5-1185.5 mm3). We attribute this antitumor efficacy to the prominent M1-type macrophage polarization caused by our nanocarriers through efficient ROS/O2 generation and targeting of M2-type TAMs via mannose ligands on coated macrophage-membrane.

Poult Sci 2019; 99:772-782. [PMID: 32036977 PMCID: PMC7587669 DOI: 10.1016/j.psj.2019.10.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 10/01/2019] [Accepted: 10/08/2019] [Indexed: 01/19/2023] Open
Abstract
Compared with mammals, the functionality of chicken cytokines is not well understood because of the unavailability of immune reagents. Mammalian interleukin (IL)-13 is an important Th2 type cytokine with well-known biological functions through its 2 receptors, IL-13 receptor (IL-13R)-α1 and IL-13Rα2. In the present study, we developed mouse monoclonal antibodies (mAb) against chIL-13 and further investigated their specificity in detecting endogenously produced chIL-13. Upon characterization of mAb using indirect ELISA and Western blot, the capture ELISA was developed for detecting chIL-13. Neutralizing effects were tested by measuring nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in primary chicken monocytes stimulated with chIL-13, lipopolysaccharide (LPS), chIL-13+LPS, or chIL-13+LPS+mAb. In addition, gene expression of chIL-13Rα1, chIL-13Rα2, and TGF-β1 was tested in chicken monocytes treated with chIL-13 or chIL-13+mAb. Based on indirect ELISA, 5 mAb that detected recombinant chIL-13 were identified, and all of them specifically detected recombinant chIL-13 protein by Western blotting. An optimal signal was obtained with 2 mAb (#9B11 and #10A2) in a pairing assay, and these 2 mAb were used in a capture assay. A neutralization assay further revealed that chIL-13 reduced LPS-stimulated NO production and iNOS expression in monocytes and macrophage cells, and the 2 mAb (#9B11 and #10A2) abrogated these effects. In addition, chIL-13-induced expressions of chIL-13Rα2 and TGF-β1 were neutralized by the 2 mAb. In summary, the present study showed that chIL-13 may be involved in the alternative activation of primary monocytes in chickens and that chIL-13 signaling may be regulated through chIL-13Rα2 binding and TGF-β1 secretion. Importantly, the newly developed anti-chIL-13 mAb will serve as valuable immune reagents for future studies on the biological activity of chIL-13 and its receptors.

Abstract
Macrophage-mediated cytotoxicity is controlled by surface receptor expression and activation. Despite the numerous studies documenting the role of macrophage C-type lectin receptors (CLR) in pathogen elimination, little is known about their contribution to antitumor responses. Here, we report that IL13 inhibits T-cell lymphoma and ovarian adenocarcinoma development in tumor-bearing mice through the conversion of tumor-supporting macrophages to cytotoxic effectors, characterized by a CLR signature composed of dectin-1 and mannose receptor (MR). We show that dectin-1 and MR are critical for the recognition of tumor cells through sialic acid-specific glycan structure on their surface and for the subsequent activation of macrophage tumoricidal response. Finally, we validated that IL13 antitumor effect mediated by dectin-1 and MR overexpression on macrophages can extend to various types of human tumors. Therefore, these results identify these CLRs as potential targets to promote macrophage antitumor response and represent an attractive approach to elicit tumor-associated macrophage tumoricidal properties.

Potential Risks Related to Modulating Interleukin-13 and Interleukin-4 Signalling: A Systematic Review. Drug Saf 2018; 41:489-509.

Abstract
Introduction Interleukin-13 and interleukin-4 are type-II cytokines signalling through the shared type II interleukin-4 receptor. As a result of their structural similarity, interleukin-13 and interleukin-4 have overlapping functions in the mediation of type-II-driven diseases and are, therefore, promising targets of biologic drugs currently in development for the treatment of such diseases, including asthma and atopic dermatitis. Objective This systematic review was conducted to assess preclinical evidence of potential safety concerns related to blockade of interleukin-13 alone or interleukin-13 and interleukin-4 in combination. Methods We specifically examined risks related to infection, malignancy and the cardiovascular system. We systematically searched the BIOSIS, MEDLINE and EMBASE databases to identify preclinical studies published between January 2006 and October 2016 that addressed the effects of interleukin-13/interleukin-4 blockade and modulation on the risk of infection, malignancy and cardiovascular events. To provide a clinical context, we also performed a search for clinical trials targeting the interleukin-13/interleukin-4 pathways. Relevant data from preclinical and clinical trials were abstracted and presented descriptively. Results Aside from expected evidence that inhibition of interleukin-13 and interleukin-4 impaired host responses to helminth infections, we did not identify other preclinical evidence suggesting safety risks relating to infection, malignancy or cardiovascular events. We found no evidence in clinical trials suggesting serious safety concerns, i.e. increased risk for infections, malignancy or cardiovascular events from therapeutic modulation of the interleukin-13 pathway alone or the combined interleukin-13/interleukin-4 pathways. Conclusions Although our findings are reassuring, long-term safety assessments of biologics that target the interleukin-13/interleukin-4 pathways currently in clinical development are needed.

Abstract
Studies have demonstrated that the solute carrier family 11 member 1 (SLC11A1) is heavily glycosylated and phosphorylated in macrophages. However, the mechanisms of SLC11A1 phosphorylation, and the effects of phosphorylation on SLC11A1 activity remain largely unknown. Here, the tyrosine phosphorylation of SLC11A1 is observed in SLC11A1-expressing U937 cells when differentiated into macrophages by phorbol myristate acetate (PMA). The phosphorylation of SLC11A1 is almost completely blocked by treatment with PP2, a selective inhibitor of Src family kinases. Furthermore, we found that SLC11A1 is a direct substrate for active c-Src kinase and siRNA-mediated knockdown of cellular Src (c-Src) expression results in a significant decrease in tyrosine phosphorylation. We found that PMA induces the interaction of SLC11A1 with c-Src kinase. We demonstrated that SLC11A1 is phosphorylated by Src family kinases at tyrosine 15 and this type of phosphorylation is required for SLC11A1-mediated modulation of NF-κB activation and nitric oxide (NO) production induced by LPS. Our results demonstrate important roles for c-Src tyrosine kinase in phosphorylation and activation of SLC11A1 in macrophages.

Int J Parasitol 2011; 41:685-95. [PMID: 21329692 DOI: 10.1016/j.ijpara.2011.01.008] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2010] [Revised: 01/05/2011] [Accepted: 01/18/2011] [Indexed: 11/18/2022]
Abstract
Neospora caninum is an intracellular protozoan pathogen that causes abortion in cattle. We studied how the interaction between murine conventional dendritic cells or macrophages and N. caninum influences the generation of cell-mediated immunity against the parasite. We first explored the invasion and survival ability of N. caninum in dendritic cells and macrophages. We observed that protozoa rapidly invaded and proliferated into these two cell populations. We then investigated how Neospora-exposed macrophages or dendritic cells distinguish between viable and non-viable (heat-killed tachyzoites and antigenic extract) parasites. Viable tachyzoites and antigenic extract, but not killed parasites, altered the phenotype of immature dendritic cells. Dendritic cells infected with viable parasites down-regulated the expression of MHC-II, CD40, CD80 and CD86 whereas dendritic cells exposed to N. caninum antigenic extract up-regulated the expression of MHC-II and CD40 and down-regulated CD80 and CD86 expression. Moreover, only viable tachyzoites and antigenic extract induced IL-12 synthesis by dendritic cells. MHC-II expression was up-regulated and CD86 expression was down-regulated at the surface of macrophages, regardless of the parasitic form was encountered. However, IL-12 secretion by macrophages was only observed under conditions using viable and heat-killed parasite. We then analysed how macrophages and dendritic cells were involved in inducing T-cell responses. T lymphocyte IFN-γ-secretion in correlation with IL-12 production occurred after interactions between T cells and dendritic cells exposed to viable tachyzoites or antigenic extract. By contrast, for macrophages IFN-γ production was IL-12-independent and only occurred after interactions between T cells and macrophages exposed to antigenic extract. Thus, N. caninum-induced activation of murine dendritic cells, but not that of macrophages, was associated with T cell IFN-γ production after IL-12 secretion.
