Protective role of surface Toll-like receptor 9 expressing neutrophils in local inflammation during systemic inflammatory response syndrome in mice. Mol Immunol 2017; 90:74-86.

Abstract
Clinically, systemic inflammatory response syndrome (SIRS) occurs after serious trauma or sepsis. In sepsis, neutrophils are the major effector cells responsible for eliminating pathogens. However, the role of neutrophils in development of SIRS, especially in local inflammatory area, is controversial. In this study, we established a SIRS mouse model characterized with cytokine-mediated lethal shock by intraperitoneal injection of oligodexynucleotides containing CpG motifs (CpG ODN) in D-galactosamine (D-GalN) sensitized mice based on our previous work and found that abundant neutrophils were rapidly recruited into the peritoneal cavity, where some neutrophils expressed surface TLR9 (sTLR9), defined as sTLR9+ neutrophils. Along with the progression of SIRS, the expression of sTLR9 in sTLR9+ neutrophils isolated from peritoneal lavage cells (PLCs) was declined in accompany with an increase in the level of the inflammatory cytokine TNFα and a decrease in the level of the anti-inflammatory cytokine IL-10 in Ly6G+ PLCs. When using CCT ODN, an oligodeoxynucleotide with CCT repeats, which we have previously shown to be capable of rescuing mice from lethal shock, the expression of sTLR9 on neutrophils was significantly elevated. Adoptive therapy using early recruited neutrophil-rich PLCs containing sTLR9+ neutrophils that express high levels of sTLR9, could rescue mice from SIRS. Overall, the data reveal that the early recruited sTLR9+ neutrophils may, at least in the area of local inflammation, play a protective role during SIRS development and provide a method to rescue the patients with severe SIRS via the up-regulation of sTLR9 levels on the surface of neutrophils or via adoptive therapy with protective sub-populations of neutrophils.

Abstract
Acute graft-versus-host disease (aGvHD) is the major barrier to the broader use of allogenetic hematopoietic stem cells. However, currently these are no highly specific and efficient drugs. Monotherapy is not sufficient and more efficient and safe therapeutic regimen are urgent need. Studies demonstrated TLR9 and Stat3 signal pathways are critical for antigen-presenting cell maturation and T-cell activation, which are important mediators in aGvHD. Specific block these two critical signal pathways using their inhibitors SAT05f and nifuroxazide may be the novel strategies for aGvHD therapy. The results showed combined therapy significantly decreased the severity of aGvHD and prolonged the survival rate. Furthermore, after treatment, the activation of CD4+ effect T cells was reduced, whereas Treg cells was increased, and the cytokine release was inhibited. In conclusion, combined therapy of nifuroxazide with SAT05f may be potential for the prevention or treatment of aGvHD, providing theoretic and experimental basis.

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
An oligodeoxynucleotide with CCT repeats (CCT ODN) has been found in our previous study to selectively downregulate Toll-like receptor 7/9 (TLR7/9)-mediated immune responses both in vitro and in vivo. In this study, we unexpectedly found that CCT ODN induced severe patchy hair loss around the mouth in male F1 mice (female Balb/c × male C57BL/6) with lupus-like nephritis induced by injecting allogenic lymphocytes and also in male Balb/c mice, but not in female F1 mice and Balb/c mice and either gender of C57BL/6 mice. Increased infiltration of natural killer group 2, member D (NKG2D+) cells in hair loss skin and upregulated interferon-gamma (IFN-γ) messenger RNA expression in cultured splenocytes were observed in male Balb/c mice. The CCT ODN-conditioned supernatants of cultured mouse splenocytes caused catagen-like changes to hair follicles (HFs). We hypothesized that the CCT ODN could induce patchy hair loss in the male mice with certain genetic traits by mobilizing NKG2D+ cells to HFs and by inducing the production of IFN-γ from immune cells. Taken together these data indicated that a gender and genetic preference of immune-regulatory oligonucleotides is causing unexpected clinical situations such as hair loss.

Abstract
Excessive innate immune response could contribute to the pathogenesis of inflammatory and autoimmune diseases. It is required to develop agents to inhibit the overwhelming innate immune response. SAT05f, an inhibitory ODN with CCT repeat sequence found in human microsatellite DNA, has been demonstrated to down-regulate TLR7/9-mediated innate immune response, protect mice from D-GalN/CpG ODN induced lethal shock, and reduce anti-ssDNA antibody level in the lupus-prone mice induced by chronic graft versus host disease (cGVHD). In this article, to explore the structure-activity relationship of SAT05f, we designed and synthesized a series of ODNs based on the sequence of SAT05f by changing repeat number of the CCT unit, substituting CCT unit with AAG at 3' end or 5' end or in the middle and by forming hairpin at 5' or 3' end, and tested their inhibitory effect on the CpG ODN induced proliferation and TNF-α production in murine immune cells. The results indicated that 1) at least 8 CCT units were required for a CCT repeat ODN to display its inhibitory activity; 2) CCT unit at 3' end of SAT05f was necessary for its full inhibitory activity; and 3) 5' end of SAT05f could be modified to design a more potent SAT05f derived inhibitory ODN. The data provided here would be helpful for finding a potent inhibitory ODN as a candidate medicament for the treatment of diseases associated with over-activated innate immune response.
