Lactic acid bacteria (LAB) represent a heterogeneous group of microorganisms that are naturally present in many foods and possess a wide range of therapeutic properties. The aim of this paper is to present an overview of the current expanding knowledge of one of the mechanisms by which LAB and other probiotic microorganisms participate in the prevention and treatment of gastrointestinal inflammatory disease through their immune-modulating properties. A special emphasis will be placed on the critical role of the anti-inflammatory cytokine IL-10, and a brief overview of the uses of genetically engineered LAB that produce this important immune response mediator will also be discussed. Thus, this paper will demonstrate the critical role that IL-10 plays in gastrointestinal inflammatory diseases and how probiotics could be used in their treatment.

Abstract Background: IL-35 is a newly anti-inflammatory cytokine which belong to the IL-12 family. Mast cells, as one of the major effector cells in the immune response system, play important roles in the pathogenesis of chronic spontaneous urticarial (CSU). The aim of our study is to explore the inhibited role of IL-35 in HMC-1. Methods: The effects of IL-35 on cell proliferation, cytokine expression and histamine release in human mast cell line (HMC­1) were investigated by CCK8, ELISA or RT-PCR. The phosphorylation of ERK1/2, p38 and JNK1/2, in PMA and A23187 induced HMC-1 cells were detected by Western Blot.Results: We found that IL-35 significantly inhibited the proliferation of HMC-1 cells stimulated by PMA and A23187. IL-35 also down-regulates the released of histamine and the mRNA expression of IL-6 and IL-17 in activated HMC-1. Furthermore, IL-35 markedly inhibited the phosphorylation of ERK1/2, p38 and JNK1/2, in PMA and A23187 induced HMC-1 cells. Conclusions: This study provides first observations on the inhibitory and anti-inflammtory effect of IL-35 on activated HMC-1 cells. We suggest that IL35 may play an inhibited role in the pathogenesis of CSU.

Natural Honey

Cancer was predicted as the leading cause of death and the most important obstacle to the increased life expectancy in the 21st century worldwide. The WHO estimated number of new cases of cancers in 2020 about 19 million, and this number is estimated to be more than 295,300,000 people up to 2040 (more than 55% increase during next 20 years). Standard treatments for cancer include surgery, radiotherapy, and chemotherapy. However, all of these methods have dangerous side effects, so researchers are more interested in finding more novel and less risky therapies. In recent years, there has been a great deal of interest in the development of anticancer agents obtained from foods or natural products. The relative safety of natural and food-derived compounds makes them attractive alternatives to conventional cancer treatment drugs. As a result, the majority of people are adviced to use complementary and alternative medicine to treat and prevent cancer. In recent years, honey, as a natural product, has attracted many researchers' attention as an alternative to conventional anticancer drugs. Natural honey has long been used as a medicine and nutrient and its beneficial effects on various diseases in animal and human models have been studied. It was found that it has a wide range of therapeutic properties, including antioxidant, antibacterial, antiviral, anti-fungal, anti-diabetic, anti-inflammatory, anti-hypertensive, antiarrhythmic, wound healing, and liver protection benefits. This article aimed to review the role of natural honey in the prevention and treatment of a number of important cancers and their subsequent complications.

Background:: Ferritin is a molecule that plays many roles being the storage for iron, signalling molecule, and modulator of the immune response. Methods:: Different electronic databases were searched in a non-systematic way to find out the literature of interest. Results:: The level of ferritin rises in many inflammatory conditions including autoimmune disorders. However, in four inflammatory diseases (i.e., adult-onset Still’s diseases, macrophage activation syndrome, catastrophic antiphospholipid syndrome, and sepsis), high levels of ferritin are observed suggesting it as a remarkable biomarker and pathological involvement in these diseases. Acting as an acute phase reactant, ferritin is also involved in the cytokine-associated modulator of the immune response as well as a regulator of cytokine synthesis and release which are responsible for the inflammatory storm. Conclusion:: This review article presents updated information on the role of ferritin in inflammatory and autoimmune diseases with an emphasis on hyperferritinaemic syndrome.

The Impact

The inflammatory gene NLRP7 is the major gene responsible for recurrent complete hydatidiform moles (CHM), an abnormal pregnancy that can develop into gestational choriocarcinoma (CC). However, the role of NLRP7 in the development and immune tolerance of CC has not been investigated. Three approaches were employed to define the role of NLRP7 in CC development: (i) a clinical study that analyzed human placenta and sera collected from women with normal pregnancies, CHM or CC; (ii) an in vitro study that investigated the impact of NLRP7 knockdown on tumor growth and organization; and (iii) an in vivo study that used two CC mouse models, including an orthotopic model. NLRP7 and circulating inflammatory cytokines were upregulated in tumor cells and in CHM and CC. In tumor cells, NLRP7 functions in an inflammasome-independent manner and promoted their proliferation and 3D organization. Gravid mice placentas injected with CC cells invalidated for NLRP7, exhibited higher maternal immune response, developed smaller tumors, and displayed less metastases. Our data characterized the critical role of NLRP7 in CC and provided evidence of its contribution to the development of an immunosuppressive maternal microenvironment that not only downregulates the maternal immune response but also fosters the growth and progression of CC.

AbstractCancer metabolism has undergone a resurgence in the last decade, 70 years after Warburg described aerobic glycolysis as a feature of cancer cells. A wide range of techniques have elucidated the complexity and heterogeneity in preclinical models and clinical studies. What emerges are the large differences between tissues, tumour types and intratumour heterogeneity. However, synergies with inhibition of metabolic pathways have been found for many drugs and therapeutic approaches, and a critical role of window studies and translational trial design is key to success.

Animal Use

How people coexist and interact with animals has become an intensely debated issue in recent times, particularly with the rise of the animal protection movement following the publication of Peter Singer’s book Animal Liberation in 1975. This paper discusses some shortcomings of the philosophical positions taken in this complex debate. Singer has helped put animals on a new footing as a group that cannot morally be ignored, but his focus is mainly on individual, familiar animals that are used or abused by humans. The argument of this paper is that the ethics of managing wildlife hinges on a broader view of animals, and their contexts, than is apparent from Singer’s text. Wildlife managers aim to conserve populations of a wide range of species, and their habitats, but some mechanisms for achieving these aims, such as research and the control of invasive animals, are frequently opposed by elements of the animal protection movement. We need to adapt our attitude to animals, particularly wildlife, away from the traditional legacy of a few familiar species to embrace an ethic that is more ecological and relevant to Australian contexts. The case argued here has been to see the critical role of context — geographical, ecological, historical, relational — as a basis for a degree of reconciliation between conservation-oriented wildlife managers and the rising interest in the ethics of animal use. There is much to be gained for zoologists, wildlife managers and conservation biologists by framing key elements of their case in ethical arguments. Conversely, the challenge for those in the animal protection movement is to expand their philosophical ideas to include the ethical imperative of the conservation of populations of wildlife.

Introduction. Mortality rate in trauma complicated with sepsis is exceeding 50%. Outcome is not determined only by infection or trauma, but also by the intensity of immuno-inflammatory response. Objective. The aim of this study was to determine the influence of sepsis on the immuno-inflammatory response, in the group of 35 traumatized men, of which in 25 cases trauma was complicated with sepsis. Methods. Cytokines were measured by ELISA test in plasma. Blood samples were drown on the first, third and fifth day after ICU admission. Results. Proinflammatory cytokine IL-8 was 230-fold higher in trauma + sepsis group (1148.48 vs. 5.05 pg/ml; p<0.01), and anti- inflammatory cytokine IL-1ra was 4-fold higher (1138.3 vs. 310.05 pg/ml; p<0.01), whereas IL-12 and IL-4 showed no significant difference between the groups. Conclusion. We concluded that sepsis, as a complication after trauma, drastically enhances immuno-inflammatory response to insult, as indicated by IL-8 and IL-1ra, but not IL-12 and IL-4.

Histone Modifying Enzymes

Histone-modifying enzymes play a critical role in chromatin remodeling and are essential for influencing several genome processes such as gene expression and DNA repair, replication, and recombination. The discovery of lysine-specific demethylase 1 (LSD1), the first identified histone demethylase, dramatically revolutionized research in the field of epigenetics. LSD1 plays a pivotal role in a wide range of biological operations, including development, cellular differentiation, embryonic pluripotency, and disease (for example, cancer). This mini-review focuses on the role of LSD1 in chromatin regulatory complexes, its involvement in epigenetic changes throughout development, and its importance in physiological and pathological processes.
