Abstract
Background Iron has important roles as an essential nutrient for all life forms and as an effector of the host defense mechanism against pathogenic infection. Lipocalin 2 (LCN2), an innate immune protein, plays a crucial role in iron transport and inflammation. In the present study, we examined the role of LCN2 in immune cells during Mycobacterium tuberculosis (Mtb) infection. Results We found that infection with Mtb H37Ra induced LCN2 production in bone marrow-derived dendritic cells (BMDCs). Notably, expression of MHC class I molecules was significantly reduced in LCN2−/− BMDCs during Mtb infection. The reduced expression of MHC class I molecules was associated with the formation of a peptide loading complex through LCN2-mediated reactive oxygen species production. The reduced expression of MHC class I molecules affected CD8+ T-cell proliferation in LCN2−/− mice infected with Mtb. The difference in the population of CD8+ effector T cells might affect the survival of intracellular Mtb. We also found a reduction of the inflammation response, including serum inflammatory cytokines and lung inflammation in LCN2−/− mice, compared with wild-type mice, during Mtb infection. Conclusions These data suggest that LCN2-mediated reactive oxygen species affects expression of MHC class I molecules in BMDCs, leading to lower levels of CD8+ effector T-cell proliferation during mycobacterial infection.

Abstract
Tumor hypoxia occurs because of an increased demand for oxygen by the rapidly growing tumor cells, together with reduction in the oxygen supply due to malformed and nonfunctional tumor vasculature. The effects of tumor hypoxia on radiotherapy (RT) are well known; however, recent findings suggest it may also suppress immunotherapy, although the mechanisms governing this observation remain undetermined. Our laboratory and others have shown that IFN-γ conditions the tumor milieu and is important for the efficacy of RT. Thus, we hypothesized that hypoxia could inhibit IFN-γ–mediated antitumor responses, resulting in decreased RT efficacy. This inhibition could involve the production and/or the cellular response to IFN-γ. To test this, we used murine tumor cell lines B16F0 and Colon38. We observed that hypoxia inhibited upregulation of IFN-γ–dependent MHC class I expression by tumor cells along with the gene expression of IFN-γ–dependent chemokines CXCL9 and CXCL10, essential for immune cell infiltration. Furthermore, CD8+ T cells, an important source of IFN-γ, which mediate effector antitumor responses, had reduced ability to proliferate and generate IFN-γ under hypoxic conditions in vitro. Interestingly, reoxygenation restored the cytokine-producing capability of these cells. Studies performed in vivo using a mouse tumor model and the hypoxia marker EF5 demonstrated that RT could reverse the hypoxia within treated tumors. This study has identified a unique mechanism of hypoxia-induced immune suppression involving the downregulation of IFN-γ production and cellular responsiveness to this essential cytokine. These results suggest that therapies that target and reduce tumor hypoxia can potentially boost antitumor immune responses.

Abstract
The ability of pathogens to sequester iron from their host cells and proteins affects their virulence. Moreover, iron is required for various innate host defense mechanisms as well as for acquired immune responses. Therefore, intracellular iron concentration may influence the interplay between pathogens and immune system. Here, we investigated whether changes in iron concentrations and intracellular ferritin heavy chain (FTH) abundance may modulate the expression of Major Histocompatibility Complex molecules (MHC), and susceptibility to Natural Killer (NK) cell cytotoxicity. FTH downregulation, either by shRNA transfection or iron chelation, led to MHC surface reduction in primary cancer cells and macrophages. On the contrary, mouse embryonic fibroblasts (MEFs) from NCOA4 null mice accumulated FTH for ferritinophagy impairment and displayed MHC class I cell surface overexpression. Low iron concentration, but not FTH, interfered with IFN-γ receptor signaling, preventing the increase of MHC-class I molecules on the membrane by obstructing STAT1 phosphorylation and nuclear translocation. Finally, iron depletion and FTH downregulation increased the target susceptibility of both primary cancer cells and macrophages to NK cell recognition. In conclusion, the reduction of iron and FTH may influence the expression of MHC class I molecules leading to NK cells activation.

Abstract
Triple negative breast cancer (TNBC) represents approximately 15% of breast cancers and is characterized by lack of expression of both estrogen receptor (ER) and progesterone receptor (PR), together with absence of human epidermal growth factor 2 (HER2). TNBC has attracted considerable attention due to its aggressiveness such as large tumor size, high proliferation rate, and metastasis. The absence of clinically efficient molecular targets is of great concern in treatment of patients with TNBC. In light of the complexity of TNBC, we applied a systematic and integrative transcriptomics and interactomics approach utilizing transcriptional regulatory and protein-protein interaction networks to discover putative transcriptional control mechanisms of TNBC. To this end, we identified TNBC-driven molecular pathways such as the Janus kinase-signal transducers, and activators of transcription (JAK-STAT) and tumor necrosis factor (TNF) signaling pathways. The multi-omics molecular target and biomarker discovery approach presented here can offer ways forward on novel diagnostics and potentially help to design personalized therapeutics for TNBC in the future.

Abstract
Although iron is essential in physiological processes, accumulation of iron in central nervous system is associated with various neurological diseases including Alzheimer's disease and Parkinson's disease. Innate immune reactions are involved in the pathogenesis of those diseases, but roles of iron in innate immunity are not known well. In the present study, pretreatment of U373MG human astrocytoma cells with an iron chelator desferrioxamine (DFX) inhibited the expression of CXCL10 induced by a Toll-like receptor 3 (TLR3) agonist polyinosinic-polycytidylic acid (poly IC). Induction of interferon-β (IFN-β) was not affected, but phosphorylation of signal transducer and transcription 1 (STAT1) was decreased by DFX. We have previously reported that various IFN-stimulated genes (ISGs) are involved in CXCL10 induction by poly IC. Pretreatment with DFX also decreased the expression of these ISGs. Pretreatment of cells with FeSO4 counteracted inhibitory effects of DFX on ISG56, retinoic acid-inducible gene-I (RIG-I), CXCL10 and phosphorylation of STAT1. These results suggest that iron may positively regulate STAT1 phosphorylation and following signaling to express ISG56, RIG-I and CXCL10 in U373MG cells treated with poly IC. Iron may contribute to innate immune and inflammatory reactions elicited by the TLR3 signaling in astrocytes, and may play an important role in neuroinflammatory diseases.

Abstract
Addison's disease is a prototypic organ-specific autoimmune disease affecting the adrenal cortex. The CXC chemokine ligand 10 (CXCL10) is expressed early in viral infections, and is produced by primary adrenocortical cells stimulated by certain cytokines. CXCL10 is also elevated in the serum of Addison's disease patients. We therefore investigated if the viral RNA substitute polyinosine-polycytidylic acid (poly (I:C)) could influence the cytokine induced production of CXCL10 by adrenocortical cells. We found that poly (I:C) could induce CXCL10 in NCI-H295R adrenocortical carcinoma cells, either alone or synergistically along with cytokines interferon-γ and tumor necrosis factor-α. This effect was found to be mediated by toll-like receptor 3 and both nuclear factor κB (NFκB) and signal transducer and activator of transcription-1 (STAT1), but not type I interferons, seemed to be involved. We propose that the combination of environmental and endogenous factors presented here, could contribute to the multifactorial pathogenesis of autoimmune Addison's disease.

Hypoxia and hypoxia mimetics inhibit TNF-dependent VCAM1 induction in the 5A32 endothelial cell line via a hypoxia inducible factor dependent mechanism. J Dermatol Sci 2011; 65:86-94. [PMID: 22093255 DOI: 10.1016/j.jdermsci.2011.10.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2011] [Revised: 08/29/2011] [Accepted: 10/06/2011] [Indexed: 12/25/2022]
Abstract
BACKGROUND We previously reported that iron chelators inhibit TNFα-mediated induction of VCAM-1 in human dermal microvascular endothelial cells. We hypothesized that iron chelators mediate inhibition of VCAM-1 via inhibition of iron-dependent enzymes such as those involved with oxygen sensing and that similar inhibition may be observed with agents which simulate hypoxia. OBJECTIVE We proposed to examine whether non-metal binding hypoxia mimetics inhibit TNFα-mediated VCAM-1 induction and define the mechanisms by which they mediate their effects on VCAM-1 expression. METHODS These studies were undertaken in vitro using immortalized dermal endothelial cells, Western blot analysis, ELISA, immunofluorescence microscopy, quantitative real-time PCR, and chromatin immunoprecipitation. RESULTS Hypoxia and the non-iron binding hypoxia mimetic dimethyl oxallyl glycine (DMOG) inhibited TNFα-mediated induction of VCAM-1. DMOG inhibition of VCAM-1 was dose-dependent, targeted VCAM-1 gene transcription independent of NF-κB nuclear translocation, and blocked TNFα-mediated chromatin modifications of relevant elements of the VCAM-1 promoter. Combined gene silencing of both HIF-1α and HIF-2α using siRNA led to a partial rescue of VCAM expression in hypoxia mimetic-treated cells. CONCLUSION Iron chelators, non-metal binding hypoxia mimetics, and hypoxia all inhibit TNFα-mediated VCAM-1 expression. Inhibition is mediated independent of nuclear translocation of NF-κB, appears to target TNFα-mediated chromatin modifications, and is at least partially dependent upon HIF expression. The absence of complete VCAM-1 expression rescue with HIF silencing implies an important regulatory role for an Fe(II)/α-ketoglutarate dioxygenase distinct from the prolyl and asparagyl hydroxylases that control HIF function. Identification of this dioxygenase may provide a valuable target for modulating inflammation in human tissues.
