Abstract
Ischemia-reperfusion injury (IRI) is a process in which damage is induced in hypoxic tissue when oxygen supply is resumed after ischemia. During IRI, restoration of reduced nitric oxide (NO) levels may alleviate reperfusion injury in ischemic organs. The protective mechanism of NO is due to anti-inflammatory effects, antioxidant effects, and the regulation of cell signaling pathways. On the other hand, it is generally known that S-nitrosylation (SNO) mediates the detrimental or protective effect of NO depending on the action of the nitrosylated target protein, and this is also applied in the IRI process. In this review, the effect of each change of NO and SNO during the IRI process was investigated.

The anti-apoptotic and anti-inflammatory effect of Lactobacillus acidophilus on Shigella sonnei and Vibrio cholerae interaction with intestinal epithelial cells: A comparison between invasive and non-invasive bacteria. PLoS One 2018; 13:e0196941.

Abstract
The aim of this study was to compare the effect of Lactobacillus acidophilus on the attachment, invasion, and interaction of Shigella sonnei and Vibrio cholerae with Caco-2 epithelial cells. Also, the anti-apoptotic and anti-inflammatory effect of L. acidophilus was investigated on S. sonnei and V. cholerae interaction with Caco-2 cells as the representatives of invasive and non-invasive intestinal bacteria. It was found that pretreatment with L. acidophilus significantly prevented from adherence and internalization of S. sonnei/V. cholerae and reduced the expression of tumour necrosis factor-α and interleukin-8 in host cells. No significant difference was observed in inhibitory effect of Lactobacilli in V. cholerae and S. sonnei attachment, emphasizing on the role of lactobacilli as a physical barrier in inhibiting direct contact with host cell by competitive exclusion, which may affect attachment and subsequent internalization of both invasive and non-invasive pathogenic bacteria in a same scale. The evaluation of early and late apoptosis in Caco-2 cells exposed to V. cholerae/S. sonnei and pretreated by L. acidophilus indicated no remarkable difference in L. acidophilus anti-apoptotic effect on Caco-2 cells against invasive and non-invasive bacterial infection. Moreover, L. acidophilus by itself showed no apoptotic effect on Caco-2 cells. Statistical analysis revealed that L. acidophilus in S. sonnei infected cells was able to reduce pro-inflammatory immune responses (TNF-α, IL-8 and IL-1β) and NO and PGE2 secretion more strongly compared with V. cholerae infected cells. These data showed for the first time that the protective effect of Lactobacilli, as a probiotic bacterium, in interaction suppression was more in invasive bacteria including S. sonnei than in non-invasive V. cholerae.

Abstract
Apoptotic cell removal or interactions of early-stage apoptotic cells with immune cells are associated with an immunomodulatory microenvironment that can be harnessed to exert therapeutic effects. While the involved immune mechanisms are still being deciphered, apoptotic cell infusion has been tested in different experimental models where inflammation is deregulated. This includes chronic and acute inflammatory disorders such as arthritis, contact hypersensitivity and acute myocardial infarction. Apoptotic cell infusion has also been used in transplantation settings to prevent or treat acute and chronic rejection, as well as to limit acute graft-versus-host disease associated with allogeneic hematopoietic cell transplantation. Here, we review the mechanisms involved in apoptotic cell-induced immunomodulation and data obtained in preclinical models of transplantation and inflammatory diseases.

Abstract
Macrophages and dendritic cells have been recognized as key players in the defense against mycobacterial infection. However, more recently, other cells in the lungs such as alveolar epithelial cells (AEC) have been found to play important roles in the defense and pathogenesis of infection. In the present study we first compared AEC with pulmonary macrophages (PuM) isolated from mice in their ability to internalize and control Bacillus Calmette-Guérin (BCG) growth and their capacity as APCs. AEC were able to internalize and control bacterial growth as well as present antigen to primed T cells. Secondly, we compared both cell types in their capacity to secrete cytokines and chemokines upon stimulation with various molecules including mycobacterial products. Activated PuM and AEC displayed different patterns of secretion. Finally, we analyzed the profile of response of AEC to diverse stimuli. AEC responded to both microbial and internal stimuli exemplified by TLR ligands and IFNs, respectively. The response included synthesis by AEC of several factors, known to have various effects in other cells. Interestingly, TNF could stimulate the production of CCL2/MCP-1. Since MCP-1 plays a role in the recruitment of monocytes and macrophages to sites of infection and macrophages are the main producers of TNF, we speculate that both cell types can stimulate each other. Also, another cell-cell interaction was suggested when IFNs (produced mainly by lymphocytes) were able to induce expression of chemokines (IP-10 and RANTES) by AEC involved in the recruitment of circulating lymphocytes to areas of injury, inflammation, or viral infection. In the current paper we confirm previous data on the capacity of AEC regarding internalization of mycobacteria and their role as APC, and extend the knowledge of AEC as a multifunctional cell type by assessing the secretion of a broad array of factors in response to several different types of stimuli.

Abstract
Apoptotic cells are cleared without an inflammatory response such as neutrophil infiltration. The mechanism underlying such silent cleanup of apoptotic cells has been intensively investigated in vitro for over a decade, and the concept that active suppression via IL-10, TGF-β, and nitric oxide enables such silent cleanup to occur has been emerging. However, because this concept has not been vigorously examined under a variety of experimental conditions in vivo, the possibility remains that a null response, in which neither cytokines nor nitric oxide is produced upon an encounter with apoptotic cells, is responsible for silent cleanup.

Abstract
Efficient execution of apoptotic cell death followed by efficient clearance mediated by professional macrophages is a key mechanism in maintaining tissue homeostasis. Removal of apoptotic cells usually involves three central elements: 1) attraction of phagocytes via soluble "find me" signals, 2) recognition and phagocytosis via cell surface-presenting "eat me" signals, and 3) suppression or initiation of inflammatory responses depending on additional innate immune stimuli. Suppression of inflammation involves both direct inhibition of proinflammatory cytokine production and release of anti-inflammatory factors, which all contribute to the resolution of inflammation. In the current study, using wild-type and adenosine A(2A) receptor (A2AR) null mice, we investigated whether A2ARs, known to mediate anti-inflammatory signals in macrophages, participate in the apoptotic cell-mediated immunosuppression. We found that macrophages engulfing apoptotic cells release adenosine in sufficient amount to trigger A2ARs, and simultaneously increase the expression of A2ARs, as a result of possible activation of liver X receptor and peroxisome proliferators activated receptor δ. In macrophages engulfing apoptotic cells, stimulation of A2ARs suppresses the NO-dependent formation of neutrophil migration factors, such as macrophage inflammatory protein-2, using the adenylate cyclase/protein kinase A pathway. As a result, loss of A2ARs results in elevated chemoattractant secretion. This was evident as pronounced neutrophil migration upon exposure of macrophages to apoptotic cells in an in vivo peritonitis model. Altogether, our data indicate that adenosine is one of the soluble mediators released by macrophages that mediate engulfment-dependent apoptotic cell suppression of inflammation.

Abstract
During inflammation, neutrophils infiltrate into the involved site and undergo apoptosis. Early apoptotic neutrophils are then cleared by phagocytes, leading to resolution of the inflammation, whereas if late apoptotic neutrophils are accumulated for some reason, they provoke proinflammatory responses such as TNF-α production. To determine how endogenously produced nitric oxide (NO) regulates neutrophil apoptosis and the resolution of inflammation, we compared peritoneal inflammation induced by Staphylococcus aureus bioparticles in wild type mice with that in inducible NO synthase (iNOS)-deficient ones. In this model, NO production was largely dependent on iNOS, the NO level peaking at 24 h. There were increases in the numbers of neutrophils and late apoptotic ones at 24 h in iNOS-deficient mice as compared with in wild type ones, and consequently TNF-α production at 36 h in iNOS-deficient mice. On the other hand, the administration of a NO donor to iNOS-deficient mice at 12 h decreased the numbers of neutrophils and late apoptotic ones at 24 h, and thereafter TNF-α production at 36 h. In addition, coculturing of macrophages with late apoptotic neutrophils caused TNF-α production and a NO donor inhibited the transmigration of neutrophils in a dose-dependent manner. Collectively, these results suggest a novel mechanism that endogenously produced NO suppresses neutrophil accumulation at a late stage of inflammation, thereby preventing the appearance of late apoptotic neutrophils and subsequent proinflammatory responses.

Abstract
In 1992 nitric oxide (NO) was declared molecule of the year by Science magazine, and ever since research on this molecule continues to increase. Following this award, NO was shown to be a mediator/protector of ischemia and reperfusion injury in many organs, such as the heart, liver, lungs, and kidneys. Controversy has existed concerning the actual protective effects of NO. However, literature from the past 15 years seems to reinforce the consensus that NO is indeed protective. Some of the protective actions of NO in ischemia and reperfusion are due to its potential as an antioxidant and anti-inflammatory agent, along with its beneficial effects on cell signaling and inhibition of nuclear proteins, such as NF-kappa B and AP-1. New therapeutic potentials for this drug are also continuously emerging. Exogenous NO and endogenous NO may both play protective roles during ischemia and reperfusion injury. Sodium nitroprusside and nitroglycerin have been used clinically with much success; though only recently have they been tested and proven effective in attenuating some of the injuries associated with ischemia and reperfusion. NO inhalation has, in the past, mostly been used for its pulmonary effects, but has also recently been shown to be protective in other organs. The potential of NO in the treatment of ischemic disease is only just being realized. Elucidation of the mechanism by which NO exerts its protective effects needs further investigation. Therefore, this paper will focus on the mechanistic actions of NO in ischemia and reperfusion injury, along with the compound's potential therapeutic benefits.

Abstract
IL-10 is known to suppress the inflammatory responses in a variety of experimental models. Because we previously found that whole-body X-irradiation causes massive apoptosis in the thymus and transient infiltration of neutrophils, in this study, we examined whether or not IL-10 is involved in the regulation of neutrophil infiltration upon whole-body X-ray irradiation using IL-10 knockout mice. Although IL-10 was induced in the thymus on whole-body X-ray irradiation, apoptosis of thymocytes, neutrophil infiltration, and MIP-2 and KC production in the thymus were not affected by an IL-10 deficiency. Coculturing of bone marrow-derived macrophages with late apoptotic cells caused MIP-2 production, which was also not affected by an IL-10 deficiency. These results suggest the uniqueness of the inflammatory response induced by whole-body X-ray irradiation, which does not seem to be regulated by IL-10.

Abstract
Apoptotic cells are removed by phagocytes without causing inflammation. It remains largely unresolved whether anti-inflammatory mediators prevent neutrophil infiltration upon apoptotic cell clearance in vivo. In this study, we showed that, upon induction of apoptosis in the thymus by x-ray, inducible NO synthase knockout (KO) mice exhibited higher levels of neutrophil infiltration and production of MIP-2 and keratinocyte-derived chemokine (KC) in the thymus than wild-type (WT) mice. Furthermore, administration of NG-nitro-L-arginine methyl ester, an inhibitor of NO synthase, to x-irradiated WT mice increased the level of neutrophil infiltration to that of KO mice by the augmentation of MIP-2 and KC production. Additionally, thymic macrophages isolated from x-irradiated KO mice produced more MIP-2 and KC than those from WT mice. Thus, although apoptosis is believed to be noninflammatory, this is actually achieved by the production of immunosuppressive signals such as NO that counteract proinflammatory chemokines such as MIP-2 and KC.
