Abstract
Introducing metabolic pathways to the gut is important to tailor the biochemical components ultimately absorbed by the host. Given identical diets, hosts possessing different consortia of gut bacteria can exhibit distinct health outcomes regulated by metabolic capabilities of the gut microbiota. The disparate competency of the population to metabolize isoflavones, such as dietary daidzein, has shown health benefits for those individuals possessing gut bacteria capable of producing equol from daidzein-rich diets. To begin addressing health inequalities due to gut metabolic pathway deficiencies, we developed a probiotic that allows metabolism of isoflavones to provide a gut phenotype paralleling that of natural equol producers. Toward this goal, we engineered Escherichia coli to produce the enzymes necessary for conversion of daidzein to equol, and as demonstrated in a murine model, these bacteria enabled elevated serum equol levels to dietary daidzein, thus serving as a starting point for more sophisticated systems.

Abstract
The human body has a large, diverse community of microorganisms which not only coexist with us, but also perform many important physiological functions, including metabolism of dietary compounds that we are unable to process ourselves. Furthermore, these bacterial derived/induced metabolites have the potential to interact and influence not only the local gut environment, but the periphery via interaction with and modulation of cells of the immune and nervous system. This relationship is being further appreciated every day as the gut microbiome is researched as a potential target for immunomodulation. A common feature among inflammatory diseases including relapsing-remitting multiple sclerosis (RRMS) is the presence of gut microbiota dysbiosis when compared to healthy controls. However, the specifics of these microbiota-neuro-immune system interactions remain unclear. Among all factors, diet has emerged as a strongest factor regulating structure and function of gut microbial community. Phytoestrogens are one class of dietary compounds emerging as potentially being of interest in this interaction as numerous studies have identified depletion of phytoestrogen-metabolizing bacteria such as Adlercreutzia, Parabacteroides and Prevotella in RRMS patients. Additionally, phytoestrogens or their metabolites have been reported to show protective effects when compounds are administered in the animal model of MS, Experimental Autoimmune Encephalomyelitis (EAE). In this review, we will illustrate the link between MS and phytoestrogen metabolizing bacteria, characterize the importance of gut bacteria and their mechanisms of action in the production of phytoestrogen metabolites, and discuss what is known about the interactions of specific compounds with cells immune and nervous system. A better understanding of gut bacteria-mediated phytoestrogen metabolism and mechanisms through which these metabolites facilitate their biological actions will help in development of novel therapeutic options for MS as well as other inflammatory diseases.

Abstract
The microflora of the digestive tract is composed of a unique set of bacteria, yeasts, viruses and other microorganisms, generally known as the microbiome. The microbiome exhibits considerable inter-individual variability, with up to two-thirds of the microflora differing between individuals. Because of this, the variable intestinal microflora is responsible for many differences in metabolic, hormonal and immunological processes in humans and animals. Significant differences have been observed in the metabolism of phytoestrogens, naturally occurring substances that possess estrogenic or anti-estrogenic activity. These substances occur predominately in legumes, especially in soy and many soy products. Because of their effects, phytoestrogens are used as an alternative therapy for menopausal disorders and benign prostate hyperplasia. In connection with the worldwide expansion of soy products as part of healthy lifestyles including vegetarianism and veganism, phytoestrogens have become a regular part of everyday life. The activity of phytoestrogens is strongly dependent on the microbiome. Their metabolites have stronger estrogenic activity than the natural substances themselves, and because of the variability in microbiomes, there are large differences in the effects of phytoestrogens among individuals.

Abstract
Postmenopausal osteoporosis (PMO) is a prevalent metabolic bone disease characterized by bone loss and structural destruction, which increases the risk of fracture in postmenopausal women. Owing to the high morbidity and serious complications of PMO, many efforts have been devoted to its prophylaxis and treatment. The intestinal microbiota is the complex community of microorganisms colonizing the gastrointestinal tract. Probiotics, which are dietary or medical supplements consisting of beneficial intestinal bacteria, work in concert with endogenous intestinal microorganisms to maintain host health. Recent studies have revealed that bone loss in PMO is closely related to host immunity, which is influenced by the intestinal microbiota. The curative effects of probiotics on metabolic bone diseases have also been demonstrated. The effects of the intestinal microbiota on bone metabolism suggest a promising target for PMO management. This review seeks to summarize the critical effects of the intestinal microbiota and probiotics on PMO, with a focus on the molecular mechanisms underlying the pathogenic relationship between bacteria and host, and to define the possible treatment options.
