Tan DX. Mitochondrial dysfunction, a weakest link of network of aging, relation to innate intramitochondrial immunity of DNA recognition receptors. Mitochondrion 2024; 76:101886. [PMID: 38663836 DOI: 10.1016/j.mito.2024.101886] [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: 02/11/2024] [Revised: 04/21/2024] [Accepted: 04/22/2024] [Indexed: 04/30/2024]
Abstract
Aging probably is the most complexed process in biology. It is manifested by a variety of hallmarks. These hallmarks weave a network of aging; however, each hallmark is not uniformly strong for the network. It is the weakest link determining the strengthening of the network of aging, or the maximum lifespan of an organism. Therefore, only improvement of the weakest link has the chance to increase the maximum lifespan but not others. We hypothesize that mitochondrial dysfunction is the weakest link of the network of aging. It may origin from the innate intramitochondrial immunity related to the activities of pathogen DNA recognition receptors. These receptors recognize mtDNA as the PAMP or DAMP to initiate the immune or inflammatory reactions. Evidence has shown that several of these receptors including TLR9, cGAS and IFI16 can be translocated into mitochondria. The potentially intramitochondrial presented pathogen DNA recognition receptors have the capacity to attack the exposed second structures of the mtDNA during its transcriptional or especially the replicational processes, leading to the mtDNA mutation, deletion, heteroplasmy colonization, mitochondrial dysfunction, and alterations of other hallmarks, as well as aging. Pre-consumption of the intramitochondrial presented pathogen DNA recognition receptors by medical interventions including development of mitochondrial targeted small molecule which can neutralize these receptors may retard or even reverse the aging to significantly improve the maximum lifespan of the organisms.

Screening of Optimal CpG-Oligodeoxynucleotide for Anti-Inflammatory Responses in the Avian Macrophage Cell Line HD11. J Poult Sci 2023; 60:2023002. [PMID: 36756048 PMCID: PMC9884633 DOI: 10.2141/jpsa.2023002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Accepted: 07/28/2022] [Indexed: 01/25/2023] Open
Abstract
CpG-oligodeoxynucleotides (. CpG-ODNs ) have been shown to possess immunostimulatory features in both mammals and birds. However, compared to their proinflammatory effects, little is known about the anti-inflammatory responses triggered by CpG-ODN in avian cells. Hence, in this study, the anti-inflammatory response in the chicken macrophage cell line HD11 was characterized under stimulation with five types of CpG-ODNs: CpG-A1585, CpG-AD35, CpG-B1555, CpG-BK3, and CpG-C2395. Single-stimulus of CpG-B1555, CpG-BK3, or CpG-C2395 induced interleukin (IL)-10 expression without causing cell injury. The effects of pretreatment with CpG-ODNs before subsequent lipopolysaccharide stimulation were also evaluated. Interestingly, pretreatment with only CpG-C2395 resulted in high expression levels of IL-10 mRNA in the presence of lipopolysaccharide. Finally, gene expression analysis of inflammation-related cytokines and receptors revealed that pre-treatment with CpG-C2395 significantly reduced the mRNA expression of tumor necrosis factor-α, IL-1β, IL-6, and Toll-like receptor 4. Overall, these results shed light on the anti-inflammatory responses triggered by CpG-C2395 stimulation through a comparative analysis of five types of CpG-ODNs in chicken macrophages. These results also offer insights into the use of CpG-ODNs to suppress the expression of proinflammatory cytokines, which may be valuable in the prevention of avian infectious diseases in the poultry industry.

Polyphenol containing Sargassum horneri attenuated Th2 differentiation in splenocytes of ovalbumin-sensitised mice: involvement of the transcription factors GATA3/STAT5/NLRP3 in Th2 polarization. PHARMACEUTICAL BIOLOGY 2021; 59:1464-1472. [PMID: 34726583 PMCID: PMC8567878 DOI: 10.1080/13880209.2021.1992451] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 09/09/2021] [Accepted: 10/07/2021] [Indexed: 05/10/2023]
Abstract
CONTEXT Sargassum horneri (Turner) C. Agardh (Sargassaceae) is a brown marine alga used in oriental medicine to treat allergic conditions. OBJECTIVE This study clarifies the effect of polyphenol-containing S. horneri ethanol extract (SHE) on T-helper type-2 (Th2) polarisation. MATERIALS AND METHODS All mice (BALB/c mice, n = 12) except in the healthy control group were first sensitised with an intraperitoneal injection of ovalbumin (OVA; 20 µg) and alum (2 mg) on Day 0 and Day 14. Similarly, phosphate-buffered saline (PBS) was injected according to the same schedule into the healthy control mice. After the final administration, splenocytes were obtained. OVA sensitised mice were challenged with OVA (100 µg/mL) in the absence or presence (62.5 and 125 µg/mL) of SHE while healthy control group remained untreated. RESULTS SHE (0-1000 µg/mL) was not cytotoxic to splenocytes and demonstrated IC50 values of 3.27 and 3.92 mg/mL, respectively, at 24 and 48 h of incubation. SHE suppressed cell proliferation at concentrations ≥62.5 µg/mL. SHE treatment (125 µg/mL) subdued (by 1.8-fold) the population expansion of CD3+CD4+ helper T cells induced by OVA challenge. SHE attenuated the OVA-induced activation of respective transcription factors GATA3 and NLRP3. Simultaneously, highly elevated levels of cytokines interleukin (IL)-4 and IL-5 caused by OVA stimulation were removed completely and IL-13 suppressed by 1.5-fold. CONCLUSIONS SHE exhibits Th2 immune suppression under OVA stimulation via GATA3- and NLRP3-dependent IL-4, IL-5, and IL-13 suppression. Therefore, SHE could be therapeutically useful for alleviating the symptoms of allergen-mediated immune diseases.

Abstract
An extract of date (fruit of a palm tree) residue plus food-grade glutamate, acetic acid, and yeast extract (date residue extract mix, DREM) has been successfully fermented with using Lactobacillus brevis JCM 1059T to produce gamma-aminobutyric acid (GABA). Here, mouse splenocytes were found to be viable when supplemented with DREM and fermented DREM containing GABA (fDREM). The addition of DREM and fDREM resulted in the secretion of tumor necrosis factor (TNF)-α from the splenocytes, fDREM being more effective than DREM. The TNF-α secretion with DREM was elevated by exogenous addition of GABA and that with fDREM was in part mediated via A-type GABA receptors. Contrary to general understanding of the suppressive effects of GABA on various biological functions, our findings suggest that GABA-containing fDREM arguments the immune function as a food and pharmaceutical material.

Abstract
Unmethylated cytosine–guanine dinucleotide (CpG) motifs are potent stimulators of the host immune response. Cellular recognition of CpG motifs occurs via Toll-like receptor 9 (TLR9), which normally activates immune responses to pathogen-associated molecular patterns (PAMPs) indicative of infection. Oligodeoxynucleotides (ODNs) containing unmethylated CpGs mimic the immunostimulatory activity of viral/microbial DNA. Synthetic ODNs harboring CpG motifs resembling those identified in viral/microbial DNA trigger an identical response, such that these immunomodulatory ODNs have therapeutic potential. CpG DNA has been investigated as an agent for the management of malignancy, asthma, allergy, and contagious diseases, and as an adjuvant in immunotherapy. In this review, we discuss the potential synergy between synthetic ODNs and other synthetic molecules and their immunomodulatory effects. We also summarize the different synthetic molecules that function as immune modulators and outline the phenomenon of TLR-mediated immune responses. We previously reported a novel synthetic ODN that acts synergistically with other synthetic molecules (including CpG ODNs, the synthetic triacylated lipopeptide Pam3CSK4, lipopolysaccharide, and zymosan) that could serve as an immune therapy. Additionally, several clinical trials have evaluated the use of CpG ODNs with other immune factors such as granulocyte-macrophage colony-stimulating factor, cytokines, and both endosomal and cell-surface TLR ligands as adjuvants for the augmentation of vaccine activity. Furthermore, we discuss the structural recognition of ODNs by TLRs and the mechanism of functional modulation of TLRs in the context of the potential application of ODNs as wide-spectrum therapeutic agents.

Abstract
Food allergies are a growing public health concern with an estimated 8% of US children affected. Peanut allergies are also on the rise and often do not spontaneously resolve, leaving individuals at-risk for potentially life-threatening anaphylaxis throughout their lifetime. Currently, two forms of peanut immunotherapy, oral immunotherapy (OIT) and epicutaneous immunotherapy (EPIT), are in Phase III clinical trials and have shown promise to induce desensitization in many subjects. However, there are several limitations with OIT and EPIT, such as allergic side effects, daily dosing requirements, and the infrequent outcome of long-term tolerance. Next-generation therapies for peanut allergy should aim to overcome these limitations, which may be achievable with adjuvanted immunotherapy. An adjuvant can be defined as anything that enhances, accelerates, or modifies an immune response to a particular antigen. Adjuvants may allow for lower doses of antigen to be given leading to decreased side effects; may only need to be administered every few weeks or months rather than daily exposures; and may induce a long-lasting protective effect. In this review article, we highlight examples of adjuvants and formulations that have shown pre-clinical efficacy in treating peanut allergy.

Abstract
Bacterial genomic DNA has recently been shown to elicit a highly evolved immune defense. This response can be selectively triggered for a wide range of therapeutic applications, including use as a vaccine adjuvant to immunotherapies for allergy, cancer, and infectious diseases. Previously, we identified a low-concentration immune synergistic oligodeoxynucleotide (iSN-ODN, named iSN34) from Lactobacillus rhamnosus GG that has immunosynergistic activity upon costimulation of target cells with ligands of Toll-like receptor 9 (TLR9). Here, we extend that observation by demonstrating the synergistic induction (in mouse splenocytes) of IL-6 by the combination of iSN34 with cell wall components of bacteria and fungi. We observed that splenocytes pretreated with iSN34 and then costimulated with agonists for TLR1/2 (Pam3 CSK4 ), TLR4 (lipopolysaccharide), or TLR2/6 (Zymosan) exhibited enhanced accumulation of IL-6. These results suggested that the combination of iSN34 with TLR1/2, TLR4, or TLR2/6 agonists may permit the induction of a potent immune response.

Abstract
Background Bacterial genomes span a significant portion of diversity, reflecting their adaptation strategies; these strategies include nucleotide usage biases that affect chromosome configuration. Here, we explore an immuno-synergistic oligodeoxynucleotide (iSN-ODN, named iSN34), derived from Lactobacillus rhamnosus GG (LGG) genomic sequences, that exhibits a synergistic effect on immune response to CpG-induced immune activation. Methods The sequence of iSN34 was designed based on the genomic sequences of LGG. Pathogen-free mice were purchased from Japan SLC and maintained under temperature- and light-controlled conditions. We tested the effects of iSN34 exposure in vitro and in vivo by assessing effects on mRNA expression, protein levels, and cell type in murine splenocytes. Results We demonstrate that iSN34 has a significant stimulatory effect when administered in combination with CpG ODN, yielding enhanced interleukin (IL)-6 expression and production. IL-6 is a pleotropic cytokine that has been shown to prevent epithelial apoptosis during prolonged inflammation. Conclusions Our results are the first report of a bacterial-DNA-derived ODN that exhibits immune synergistic activity. The potent over-expression of IL-6 in response to treatment with the combination of CpG ODN and iSN34 suggests a new approach to immune therapy. This finding may lead to novel clinical strategies for the prevention or treatment of dysfunctions of the innate and adaptive immune systems.

Abstract
Objective: Discussing the effects of Ziyinqingre prescription on the level of airway resistance (Rrs), airway response threshold (Dmin), airway conductance (sGrs) and the level of inflammatory cytokines interleukin-4 (IL-4) and interferon-γ (IFN-γ) of the bronchial hyper-responsiveness (BHR) cough patients. Method: 84 subjects diagnosed as BHR were randomly divided into 42 Chinese Traditional medicine group and 42 control group. The Chinese Traditional Medicine group received Ziyinqingre prescription twice a day and the control group received 10mg Montelukast Sodium tablets once a day for two weeks. Observe the clinical symptoms improvement and the changes of the level of the Rrs, Dmin, sGrs and IL-4, IFN-γ. Results: After receiving the medicine, the symptoms of the Chinese medicine group were obviously alleviated, the outcome was more satisfied than that of the control group. Compared with the control group, the level of Dmin increased and sGrs level decreased more obviously (P<0.05); the level of IL-4 decreased and IFN^level increased more obviously in the Chinese medicine group (P<0.05). Conclusion: Ziyinqingre prescription can not only improve BHR patients’ symptoms, but reduce the level of bronchial responsiveness, which proved a better curative effect of Chinese medicine. The mechanism is probably due to relieving the airway inflammation by keeping the balance between Th1 and Th2 cells.

Abstract
Synthetic oligodeoxynucleotides that can down-regulate cellular elements of the immune system have been developed and are being widely studied in preclinical models. These agents vary in sequence, mechanism of action, and cellular target(s) but share the ability to suppress a plethora of inflammatory responses. This work reviews the types of immunosuppressive oligodeoxynucleotide (Sup ODN) and compares their therapeutic activity against diseases characterized by pathologic levels of immune stimulation ranging from autoimmunity to septic shock to cancer (see graphical abstract). The mechanism(s) underlying the efficacy of Sup ODN and the influence size, sequence and nucleotide backbone on function are considered.

Abstract
BACKGROUND Mucosal delivery of therapeutic proteins using genetically modified strains of lactic acid bacteria (gmLAB) is being investigated as a new therapeutic strategy. METHODS We developed a strain of gmLAB, Lactococcus lactis NZ9000 (NZ-HO), which secretes the anti-inflammatory molecule recombinant mouse heme oxygenase-1 (rmHO-1). The effects of short-term continuous oral dosing with NZ-HO were evaluated in mice with dextran sulfate sodium (DSS)-induced acute colitis as a model of inflammatory bowel diseases (IBD). RESULTS We identified the secretion of rmHO-1 by NZ-HO. rmHO-1 was biologically active as determined with spectroscopy. Viable NZ-HO was directly delivered to the colon via oral administration, and rmHO-1 was secreted onto the colonic mucosa in mice. Acute colitis in mice was induced by free drinking of 3 % DSS in water and was accompanied by an increase in the disease activity index score and histopathological changes. Daily oral administration of NZ-HO significantly improved these colitis-associated symptoms. In addition, NZ-HO significantly increased production of the anti-inflammatory cytokine interleukin (IL)-10 and decreased the expression of pro-inflammatory cytokines such as IL-1α and IL-6 in the colon compared to a vector control strain. CONCLUSIONS Oral administration of NZ-HO alleviates DSS-induced acute colitis in mice. Our results suggest that NZ-HO may be a useful mucosal therapeutic agent for treating IBD.

Development of a simple IgE-independent anaphylactic model using buckwheat antigen and B-type CpG oligodeoxynucleotide from Streptococcus thermophilus. Anim Sci J 2015; 87:710-7. [PMID: 26302702 DOI: 10.1111/asj.12479] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2015] [Revised: 04/22/2015] [Accepted: 05/13/2015] [Indexed: 01/26/2023]
Abstract
We developed a severe anaphylactic model in mice using buckwheat antigen and B-type CpG-oligodeoxynucleotides (CpG-ODNs) from Streptococcus thermophilus genome. In typical systemic anaphylaxis models, animals are challenged with large quantity of antigens via an intravenous (i.v.) route. Here, we showed a simple anaphylactic shock after challenge via intraperitoneal (i.p.) route. The i.p. method is simpler than i.v. administration and has a lower risk for failure. To generate this anaphylactic model, 5-week-old female BALB/c mice were first i.p. sensitized with buckwheat antigen mixed with B-type CpG-ODN. After 2 weeks, mice were challenged with antigen to induce anaphylactic shock, which was evaluated by scoring the severity symptoms and measuring serum levels of various proteins and splenic cell producing cytokines. Immunoglobulin (Ig)G2a production and interferon-γ positive cells were markedly increased in mice immunized with antigen mixed with B-type CpG-ODN, whereas serum IgE levels were decreased by B-type CpG-ODN. We also examined the effects of various ODNs (A, B and C-type CpG-ODNs) and antigens (buckwheat, α-casein, β-lactoglobulin and ovalbumin) on anaphylactic severity, and found that the combination of buckwheat and B-type CpG-ODN induced the most intense anaphylactic shock. This model is expected to contribute to the study of the prevention of anaphylactic shock.

Abstract
Here, we report a simple and low-cost oral oligodeoxynucleotide (ODN) delivery system targeted to the gut Peyer's patches (PPs). This system requires only Dulbecco's modified eagle's medium, calcium chloride, ODNs, and basic laboratory equipment. ODN nanocapsules (ODNcaps) were directly delivered to the PPs through oral administration and were taken up by macrophages in the PPs, where they induced an immune response. Long-term continuous oral dosing with inhibitory/suppressive ODNcaps (iODNcaps, "iSG3caps" in this study) was evaluated using an atopic dermatitis mouse model to visually monitor disease course. Administration of iSG3caps improved skin lesions and decreased epidermal thickness. Underlying this effect is the ability of iSG3 to bind to and prevent phosphorylation of signal transducer and activator of transcription 6, thereby blocking the interleukin-4 signaling cascade mediated by binding of allergens to type 2 helper T cells. The results of our iSG3cap oral delivery experiments suggest that iSG3 may be useful for treating allergic diseases.

Abstract
Previous studies showed that hydrolysates of β-lactoglobulin (BLG) prepared using gastrointestinal proteases strongly inhibit dipeptidyl peptidase-IV (DPP-IV) activity in vitro. In this study, we developed a BLG-secreting Lactococcus lactis strain as a delivery vehicle and in situ expression system. Interestingly, trypsin-digested recombinant BLG from L. lactis inhibited DPP-IV activity, suggesting that BLG-secreting L. lactis may be useful in the treatment of type 2 diabetes mellitus.

Expression of the immunoreactive buckwheat major allergenic storage protein in Lactococcus lactis. Appl Microbiol Biotechnol 2012; 97:3603-11.

Abstract
Proteins from buckwheat (Fagopyrum esculentum) are strong allergens that can cause serious symptoms, including anaphylaxis, in patients with hypersensitivity. In this study, we successfully developed a modified lactic acid bacterial vector (pNSH) and a recombinant strain of Lactococcus lactis NZ9000 (NZ9000) that produced a major allergenic storage protein of buckwheat, Fagag1 (61.2 kDa, GenBank accession number AF152003), with or without a green fluorescent protein (GFP) tag. GFP fluorescence allows for rapid, simple, and accurate measurement of target protein expression by microscopy or fluorimetry. We describe a convenient method for production of rGFP-Fagag1 fusion and rFagag1 proteins with a good yield in an advantageous probiotic host. We found that in vitro treatment of splenocytes isolated from buckwheat crude protein-immunized mice with rFagag1 increased the expression of allergic inflammation cytokines such as IL-4, IL-13, and IL-17 F. Because it was less antigenic, rGFP-Fagag1 protein from NZ9000 might be of limited use; however, rFagag1 from NZ9000 evoked a robust response as measured by induction of IL-4 and IL-17 F expression levels. The observed allergic activity is indicative of a Th2 cell-mediated immune response and is similar to the effects induced by exposure to buckwheat crude protein. Our results suggest that expression of rFagag1 in NZ9000 may facilitate in vivo applications of this system aimed at improving the specificity of immunological responses to buckwheat allergens.
