Abstract
During infection, phagocytic cells pursue homeostasis in the host via multiple mechanisms that control microbial invasion. Neutrophils respond to infection by exerting a variety of cellular processes, including chemotaxis, activation, phagocytosis, degranulation and the generation of reactive oxygen species (ROS). Calcium (Ca2+) signaling and the activation of specific Ca2+ channels are required for most antimicrobial effector functions of neutrophils. The transient receptor potential melastatin-2 (TRPM2) cation channel has been proposed to play important roles in modulating Ca2+ mobilization and oxidative stress in neutrophils. In the present study, we use a mouse model of Listeria monocytogenes infection to define the role of TRPM2 in the regulation of neutrophils' functions during infection. We show that the susceptibility of Trpm2−/− mice to L. monocytogenes infection is characterized by increased migration rates of neutrophils and monocytes to the liver and spleen in the first 24 h. During the acute phase of L. monocytogenes infection, Trpm2−/− mice developed septic shock, characterized by increased serum levels of TNF-α, IL-6, and IL-10. Furthermore, in vivo depletion of neutrophils demonstrated a critical role of these immune cells in regulating acute inflammation in Trpm2−/− infected mice. Gene expression and inflammatory cytokine analyses of infected tissues further confirmed the hyperinflammatory profile of Trpm2−/− neutrophils. Finally, the increased inflammatory properties of Trpm2−/− neutrophils correlated with the dysregulated cytoplasmic concentration of Ca2+ and potentiated membrane depolarization, in response to L. monocytogenes. In conclusion, our findings suggest that the TRPM2 channel plays critical functional roles in regulating the inflammatory properties of neutrophils and preventing tissue damage during Listeria infection.

Abstract
To investigate the role of fatty acid-binding protein 5 (FABP5) in infectious diseases, FABP5-deficient mice were challenged with Listeria monocytogenes, a facultative intracellular bacterial pathogen. Interestingly, FABP5-deficient animals were able to clear the infection within 3 days whereas control wild-type (WT) animals showed comparatively higher bacterial burdens in the liver and spleen. Sections of infected tissues showed an increase in inflammatory foci in WT mice compared to FABP5-deficient mice. FABP5-deficient mice had lower circulating inflammatory cytokines and increased inducible nitric oxide synthase production. FABP5-deficient mouse bone marrow-derived macrophages produced higher levels of nitrite anion than their WT counterparts in response to various stimuli. Additionally, in contrast to FABP5-/- mice, transgenic mice overexpressing FABP5 in myeloid cells (LysM-Cre driven) showed decreased survival rates and increased bacterial burden and inflammatory cytokines. Overall, these findings suggest that increased FABP5 levels correlate with a higher L. monocytogenes bacterial burden and elevated subsequent inflammation.

Abstract
CD163 is the macrophage receptor for uptake of hemoglobin-haptoglobin complexes. The human receptor can be shed from the macrophage surface owing to a cleavage site for the inflammation-inducible TACE/ADAM17 enzyme. Accordingly, plasma ‘soluble CD163’ (sCD163) has become a biomarker for macrophage activity and inflammation. The present study disclosed that 10% of sCD163 in healthy persons is actually extracellular vesicle (EV)-associated CD163 not being cleaved and shed. Endotoxin injection of human volunteers caused a selective increase in the ectodomain CD163, while septic patients exhibited high levels of both soluble ectodomain CD163 and extracellular vesicle (EV) CD163, the latter representing up 60% of total plasma CD163. A poor prognosis of septic patients measured as the sequential organ failure assessment (SOFA) score correlated with the increase in membrane-associated CD163. Our results show that soluble ectodomain CD163 and EV CD163 in plasma are part of separate macrophage response in the context of systemic inflammation. While that soluble ectodomain CD163 is released during the acute systemic inflammatory response, this is not the case for EV CD163 that instead may be released during a later phase of the inflammatory response. A separate measurement of the two forms of CD163 constituting ‘soluble CD163’ in plasma may therefore add to the diagnostic and prognostic value.

Abstract
This review concerns how the primary inflammation preceding the generation of certain key damage-associated molecular patterns (DAMPs) arises in Alzheimer's disease (AD). In doing so, it places soluble amyloid β (Aβ), a protein hitherto considered as a primary initiator of AD, in a novel perspective. We note here that increased soluble Aβ is one of the proinflammatory cytokine-induced DAMPs recognized by at least one of the toll-like receptors on and in various cell types. Moreover, Aβ is best regarded as belonging to a class of DAMPs, as do the S100 proteins and HMBG1, that further exacerbate production of these same proinflammatory cytokines, which are already enhanced, and induces them further. Moreover, variation in levels of other DAMPs of this same class in AD may explain why normal elderly patients can exhibit high Aβ plaque levels, and why removing Aβ or its plaque does not retard disease progression. It may also explain why mouse transgenic models, having been designed to generate high Aβ, can be treated successfully by this approach.

Abstract
Tumor necrosis factor (TNF) is an ancient and widespread cytokine required in small amounts for much physiological function. Higher concentrations are central to innate immunity, but if unchecked this cytokine orchestrates much chronic and acute disease, both infectious and noninfectious. While being a major proinflammatory cytokine, it also controls homeostasis and plasticity in physiological circumstances. For the last decade or so these principles have been shown to apply to the central nervous system as well as the rest of the body. Nevertheless, whereas this approach has been a major success in treating noncerebral disease, its investigation and potential widespread adoption in chronic neurological conditions has inexplicably stalled since the first open trial almost a decade ago. While neuroscience is closely involved with this approach, clinical neurology appears to be reticent in engaging with what it offers patients. Unfortunately, the basic biology of TNF and its relevance to disease is largely outside the traditions of neurology. The purpose of this review is to facilitate lowering communication barriers between the traditional anatomically based medical specialties through recognition of shared disease mechanisms and thus advance the prospects of a large group of patients with neurodegenerative conditions for whom at present little can be done.

Abstract
Listeriosis is an infectious and fatal disease of animals, birds, fish, crustaceans and humans. It is an important food-borne zoonosis caused by Listeria monocytogenes, an intracellular pathogen with unique potential to spread from cell to cell, thereby crossing blood-brain, intestinal and placental barriers. The organism possesses a pile of virulence factors that help to infect the host and evade from host immune machinery. Though disease occurrence is sporadic throughout the world, it can result in severe damage during an outbreak. Listeriosis is characterized by septicaemia, encephalitis, meningitis, meningoencephalitis, abortion, stillbirth, perinatal infections and gastroenteritis with the incubation period varying with the form of infection. L. monocytogenes has been isolated worldwide from humans, animals, poultry, environmental sources like soil, river, decaying plants, and food sources like milk, meat and their products, seafood and vegetables. Since appropriate vaccines are not available and infection is mainly transmitted through foods in humans and animals, hygienic practices can prevent its spread. The present review describes etiology, epidemiology, transmission, clinical signs, post-mortem lesions, pathogenesis, public health significance, and advances in diagnosis, vaccines and treatment of this disease. Special attention has been given to novel as well as prospective emerging therapies that include bacteriophage and cytokine therapy, avian egg yolk antibodies and herbal therapy. Various vaccines, including advances in recombinant and DNA vaccines and their modes of eliciting immune response, are also discussed. Due focus has also been given regarding appropriate prevention and control strategies to be adapted for better management of this zoonotic disease.

Abstract
Listeria monocytogenes induces the formation of inflammasomes and subsequent caspase-1 activation, and the adaptor apoptosis-associated speck-like protein containing a CARD (ASC) is crucial for this response. However, the role of ASC in L. monocytogenes infection in vivo is unclear. In this study, we demonstrate that ASC has a detrimental effect on host defense against L. monocytogenes infection at a lethal dose (10(6) CFU), but not at a sublethal dose (10(3) CFU). During lethal L. monocytogenes infection, serum levels of IL-18 and IL-10 were markedly elevated in WT mice, but not in ASC KO mice. IL-18 KO mice were more resistant to lethal L. monocytogenes infection than WT mice and had lower levels of serum IL-10. Furthermore, blockade of IL-10 receptor resulted in a reduction in bacterial counts, suggesting that ASC and IL-18 might exacerbate L. monocytogenes infection through induction of IL-10. We noticed that maturation of IL-18 during lethal infection was partially independent of caspase-1, but was critically dependent on ASC. ASC was required for the elevation of serum neutrophil serine protease activity, which correlated with caspase-1-independent IL-18 maturation and IL-10 production. Collectively, these results suggest that ASC plays a detrimental role in lethal L. monocytogenes infection through IL-18 production in an inflammasome-dependent and -independent manner.

Abstract
SUMMARYThis is a personal account of how tumour necrosis factor (TNF) the prototype of a group of host-origin mediators, often known as pro-inflammatory cytokines, came into parasitology, and was subsequently realised to be central to the pathogenesis of most disease pathology. This contribution summarizes an example of how a curiosity-driven outsider, with initially no intention of heading this way, and no relevant experience, and with no more than the simplest of plans but an ambition to read as widely as it takes, and (most importantly) allowed to follow his head, can be what is required to give fresh insight into understanding a disease. It also gives the author's views on aspects of how the field of malaria disease pathogenesis seems to be developing. The hope is to inspire another generation to follow a similarly original course.

Abstract
It is now broadly accepted for infectious disease in general that it is not the invading organism, but the body's unbridled response to it--the "cytokine storm"--that causes illness and pathology. Nevertheless, many researchers still regard the harmful effects of falciparum malaria as being governed by oligaemic hypoxia arising from parasitised erythrocytes obstructing blood flow through vulnerable organs, particularly the brain, and we summarise why these notions are no longer tenable. In our view, this harmful sequestration is readily accommodated within the cytokine storm perspective as one of its secondary effects. We approach these issues by examining aspects of malaria, sepsis and influenza in parallel, and discuss the insights that comparisons of the literature can provide on the validity of possible anti-disease therapies.

Abstract
Heterologous immunity, or protection by one invading organism against another across phylogenetic divides, has been recognised for decades. It was initially thought to operate largely through enhancement of phagocytosis, but this explanation became untenable when it was realised it worked extremely well against intraerythrocytic protozoa and killed them while they were free in the circulation. Clearly a soluble mediator was called for. This review summarises the logic that arose from this observation, which led to a wider appreciation of the roles of pro-inflammatory cytokines, and then nitric oxide, in the host's response against invaders, as well as the ability of these mediators to harm the host itself if they are generated too enthusiastically. This has led to a discernable pattern across heterologous immunity as a whole, and its lessons influence a range of areas, including vaccine development.

Abstract
Macrophage migration inhibitory factor (MIF) has been characterized as a proinflammatory cytokine. Previous studies have indicated that MIF may play a beneficial role or a detrimental role in microbial infections, depending on pathogens. In this study, we investigated the role of MIF in Listeria monocytogenes infection. The MIF titers increased 6h after lethal L. monocytogenes infection but not in the sublethal infection. The elimination of bacteria from the spleens and livers was not affected by anti-MIF antibody (Ab) injection in the sublethal infection, whereas anti-MIF Ab treatment rescued mice from the lethal infection, suggesting that MIF plays a deteriorating role in lethal L. monocytogenes infection. Anti-MIF Ab treatment significantly augmented interleukin (IL)-10 production in the spleens and livers 24h after infection, suggesting that MIF might down-regulate IL-10 production. Although the administration of anti-IL-10 monoclonal Ab showed no significant effect on the bacterial growth in the organs, the bacterial infection was deteriorated by the combined administration of Abs against MIF and IL-10. On the other hand, anti-MIF Ab treatment also increased in the serum cortisol titer 6h after infection compared with the control immunoglobulin G-injected group. Depletion of endogenous IL-10 decreased serum cortisol titers. These results suggested that IL-10 and cortisol might be involved in the deteriorating effect of MIF on lethal L. monocytogenes infection.

Abstract
Contact hypersensitivity (CHS) is a cutaneous T-cell-mediated immunological reaction to applied haptens. Activated antigen-specific T cells release several cytokines and chemokines followed by the recruitment of inflammatory cells and skin damage. CD8+ T cells and CD4+ T cells have been involved in the establishment of previously described CHS. In this study, we investigated the induction of CHS by urushiol in mice. Maximum swelling in mouse ears was elicited 24 h after challenge with urushiol on day 9 of sensitization. IFN-gamma, TNF-alpha and IFN-gamma-inducible protein 10 (IP-10) mRNA were expressed after challenge of the antigen in urushiol-sensitized mice, but not in unsensitized mice. IFN-gamma knockout (KO) mice and TNF-alpha KO mice failed to elicit CHS with urushiol. Contact hypersensitivity and expressions of IFN-gamma, TNF-alpha and IP-10 mRNA were markedly suppressed in CD4+ and CD8+ cell-depleted mice. These results suggest that IFN-gamma, TNF-alpha, and possibly IP-10, play a critical role in CHS induced by urushiol, depending on both CD4+ T cells and CD8+ T cells.

In this study, we compared the susceptibilities and cytokine responses between intranasal and intravenous infections with L. monocytogenes in mice. Moreover, we compared efficiency of acquisition of host resistance to L. monocytogenes infection between intranasally and intravenously immunized mice because an intranasal immunization of vaccines is reportedly available for induction of adaptive immunity against various infectious pathogens. The susceptibility to an intranasal infection with L. monocytogenes was markedly lower than that to the intravenous infection. The bacterial growth in the lungs, spleens, and livers was substantially similar between intranasally and intravenously infected mice. Titers of endogenous gamma interferon (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha) in the spleens, livers, and lungs were parallel to bacterial numbers in each organ of mice during intranasal infection and intravenous infection. IFN-gamma-deficient mice and TNF-alpha-deficient mice were highly susceptible to intranasal infection as well as intravenous infection. Susceptibilities to intranasal and intravenous L. monocytogenes infection were the same in these cytokine-deficient mice. These results suggest that both IFN-gamma and TNF-alpha play critical roles in host resistance to intranasal L. monocytogenes infection as well as the intravenous infection. Acquisition of host resistance to intravenous and intranasal L. monocytogenes infection was induced in intranasally immunized mice as well as intravenously immunized mice, suggesting that intranasal immunization is effective for prevention of a systemic infection with L. monocytogenes.

Abstract
Pregnancy sickness, a suite of "symptoms" that frequently co-occur during pregnancy, may be an adaptation providing behavioral prophylaxis against infection. Maternal immunosupression, necessary for tolerance of the fetus, results in gestational vulnerability to pathogens. Throughout the period of maximal vulnerability, dietary behavior is significantly altered via changes in nausea susceptibility and olfaction and the development of marked aversions and cravings. Of food types, meat is both the most likely to carry pathogens and the principal target of gestational aversions and pregnancy taboos. Because meat was prominent in ancestral human diets but hygienic procedures that effectively eliminate the risk of meat-borne infection are recent, such pathogens likely constituted a source of selective pressure on pregnant females throughout human history. Both the relatively low protein and energy demands of the first trimester and the existense of nonmeat alternatives would have allowed for the evolution of time-limited gestational meat-avoidance mechanisms.Complementing these mechanisms, gestational cravings target substances that may influence immune functioning and affect the availability of iron in the gastro-intestinal tract, thereby limiting the proliferation of iron-dependent pathogens. Clinical and ethnographic findings are examined in light of these proposals, and directions for future research are outlined.

Abstract
The aly is a unique spontaneous autosomal recessive mutation in mice that causes a systemic defect of lymph nodes and Peyer's patches and disorganized splenic and thymic structures with immunodeficiency. Our previous study demonstrated that resistance to Listeria monocytogenes infection and interferon-gamma (IFN-gamma) production are attenuated in the mutant mice. In this study, we investigated the mechanism of decrease in antilisterial resistance and IFN-gamma production in aly mice. Interleukin (IL)-12 production in response to heat-killed L. monocytogenes (HK-LM) was decreased but IL-10 production was increased in aly/aly macrophage cultures, compared with those in aly/+ macrophages. Nonadherent cells and macrophages obtained from the spleens of naive aly/+ mice and aly/aly mice were reconstituted and stimulated with HK-LM. IFN-gamma production was markedly decreased when macrophages derived from aly/aly mice were used. IFN-gamma production in aly/aly spleen cell cultures was recovered in the presence of anti-IL-10 monoclonal antibody (mAb) or recombinant IL-12. When aly/+ mice and aly/aly mice were injected with mAb against IL-10 or IL-12 p40, antilisterial resistance was inhibited by injection of anti-IL-12 p40 mAb, while anti-IL-10 mAb treatment augmented the resistance. Administration of anti-IFN-gamma mAb attenuated antilisterial resistance in aly/+ mice but not in aly/aly mice. The present results suggest that downregulation of IL-12 and upregulation of IL-10 in macrophages might be involved in the decrease in antilisterial resistance and IFN-gamma production in aly/aly mice in addition to the structural defect in lymphoid organs. Moreover, the results predict that an IL-12-dependent and IFN-gamma-independent mechanism may be also involved in the decrease in antilisterial resistance in aly/aly mice.

Abstract
Listeria monocytogenes promotes the induction of the T-helper 1 (Th1) cell response, while ovalbumin (OVA) induces a Th2 cell response and allergic reactions, such as airway hyperreactivity and immunoglobulin E (IgE) production. When mice were immunized with OVA on day 7 after L. monocytogenes infection, eosinophilia in bronchoalveolar lavage and the production of total IgE, OVA-specific IgE, interleukin-4 (IL-4), and IL-5 in the circulation were markedly suppressed. Cytokine responses, including IL-4, IL-5, IL-10, IL-13, and gamma interferon, to OVA were decreased in the spleen cell cultures obtained from OVA-immunized mice that had been infected with L. monocytogenes. Conversely, when OVA-immunized mice were infected with L. monocytogenes, conversion from the nonlethal infection to the lethal infection occurred. Host resistance to L. monocytogenes infection in OVA-immunized mice was enhanced by the administration of anti-IL-10 monoclonal antibody. The present study indicates that striking interference is observed between Th1-inducing L. monocytogenes infection and Th2-driven OVA-induced airway hyperreactivity.

Abstract
Hydroxy acid-based matrix metalloproteinase (MMP) inhibitors have been shown to inhibit tumor infiltration and growth, endotoxin shock, and acute graft-versus-host disease. Blockade of the release of soluble tumor necrosis factor-alpha (TNF-alpha) and CD95 ligand (CD95L; FasL) from cell-associated forms is reportedly involved in the mechanism of the drug effect. We investigated the effect of a MMP inhibitor, KB-R7785, on host resistance against Listeria monocytogenes infection, in which TNF-alpha is essentially required for the defense, in mice. The administration of KB-R7785 exacerbated listeriosis, while the drug prevented lethal shock induced by lipopolysaccharide and D-galactosamine. KB-R7785 inhibited soluble TNF-alpha production in spleen cell cultures stimulated by heat-killed L. monocytogenes and the drug treatment reduced serum TNF-alpha levels in infected mice, whereas the compound was ineffective on the modulation of interferon-gamma and interleukin-10 production. The effect of KB-R7785 was considered to be dependent on TNF-alpha because the drug failed to affect L. monocytogenes infection in anti-TNF-alpha monoclonal antibody-treated mice and TNF-alpha knockout mice. Anti-CD95L monoclonal antibody was also ineffective on the infection. These results suggest that induction of infectious diseases, to which TNF-alpha is critical in host resistance, should be considered in MMP inhibitor-treated hosts.

Abstract
Various bacterial pathogens have been identified as mediators of apoptosis. Apoptosis reportedly shows both detrimental and beneficial effects on biological functions. We studied the role of liver apoptosis in lethal Listeria monocytogenes infection and the regulation of apoptosis by endogenous cytokines during infection. Apoptosis was observed in the spleen but not in the liver of infected mice, whereas the induction of liver necrosis was evident by rising levels of serum aminotransferases in these animals. Apoptosis was detected in the liver of L. monocytogenes-infected mice which had been treated with monoclonal antibody (mAb) against tumor necrosis factor-alpha (TNF-alpha) or interleukin-6 (IL-6), or in TNF-alpha(-/-) mice, but not in gamma- interferon (IFN-gamma)(-/-) mice or mice which had been treated with mAb against IL-4 or IL-10. Augmentation of liver apoptosis in mice treated with mAb against TNF-alpha or IL-6 or in TNF-alpha(-/-) mice correlated with the increase in bacterial numbers in the organ, while no augmentation of apoptosis was observed in the liver of IFN-gamma(-/-) mice irrespective of the marked increase in bacterial numbers in the organs, indicating that augmentation of liver apoptosis may not be merely due to the increase in bacterial growth in the organs. These results suggest that TNF-alpha and IL-6 may play an important role in protecting the liver from apoptosis in lethal L. monocytogenes infection.
