REVIEW
Young Cheol Kim, Anne J Anderson
Many root-colonizing microbes are multifaceted in traits that improve plant health. Although isolates designated as biological control agents directly reduce pathogen growth, many exert additional beneficial features that parallel changes induced in animal and other hosts by health-promoting microbes termed probiotics. Both animal and plant probiotics cause direct antagonism of pathogens and induce systemic immunity in the host to pathogens and other stresses. They also alter host development, and improve host nutrition...

Numerous studies have examined the pathogenesis of osteoporosis. The causes of osteoporosis include endocrine factors, nutritional status, genetic factors, physical factors, and immune factors. Recent osteoimmunology studies demonstrated that the immune system and immune factors play important regulatory roles in the occurrence of osteoporosis, and people should pay more attention to the relationship between immunity and osteoporosis. Immune and bone cells are located in the bone marrow and share numerous regulatory molecules, signaling molecules, and transcription factors...

BACKGROUND: Both under- and over-nutrition may occur among human immunodeficiency virus (HIV)-infected individuals and impact on the course of the acquired immune deficiency syndrome (AIDS) and its management due to the close interaction between immunity and nutrition. We investigated occurrence of undernutrition, excess weight and lipid abnormalities among antiretroviral naïve HIV-infected adults in Addis Ababa, Ethiopia. METHODS: A cross-sectional study on 594 antiretroviral therapy (ART) naïve HIV-infected adults was conducted in four hospitals in Addis Ababa from February to September 2013...

Biofortification interventions have the potential to combat malnutrition. This review explored the use of provitamin A-biofortified maize (PVABM) as a vitamin A deficiency (VAD) reduction agricultural-based strategy. Maize has been identified as one of the key staple crops for biofortification to reduce hidden hunger in Africa. Most nutrition interventions have not been successful in reducing hunger because rural communities, who mainly rely on agriculture, have been indirectly excluded. The biofortification intervention proposed here aims to be an inclusive strategy, based on smallholder farming systems...

The human immune system is a fine network consisted of the innumerable numbers of functional cells that balance the immunity and tolerance against various endogenous and environmental challenges. Although advances in modern immunology have revealed a role of many unique immune cell subsets, technologies that enable us to capture the whole landscape of immune responses against specific antigens have been not available to date. Acquired immunity against various microorganisms including host microbiome is principally founded on T cell and B cell populations, each of which expresses antigen-specific receptors that define a unique clonotype...

INTRODUCTION: Dietary zinc (Zn) deficiency is a global problem, particularly in low-income and middle-income countries where access to rich, animal-source foods of Zn is limited due to poverty. In Pakistan, Zn deficiency affects over 40% of the adult female population, resulting in suboptimal immune status and increased likelihood of complications during pregnancy. METHODS AND ANALYSIS: We are conducting a double-blind, randomised controlled feeding study with cross-over design in a low-resource setting in Pakistan...

Several microorganisms belonging to the intestinal microbiota act in an ecosystem responsible for maintaining the homeostasis and vital functions of human beings. From birth to old age the diversity of the intestinal microbiota may change due to environmental factors such as nutrition, immunity, diseases or the use of antibiotics leading to dysbiosis. Improvement in microbiota diversity can be achieved by modifying related risk factors through changes in lifestyle and a healthy diet. Besides, the addition of probiotics, prebiotics or the combination of both (symbiotics), can result in the improvement of the intestinal permeability, inflammatory pathways and the immune system...

BACKGROUND: Allogeneic haematopoietic cell transplantation (HCT) is often associated with poor oral intake due to painful mucositis and gastrointestinal sequalae that occur following a preparative regimen of intensive chemotherapy and/or total body radiation. Although attractive to assume that optimal nutrition improves HCT outcomes, there are limited data to support this. It is also unclear whether artificial nutrition support should be provided as enteral tube feeding or parenteral nutrition (PN)...

The rapa whelk Rapana venosa is a commercially important gastropod in China, but a major invader worldwide. There is little information on the bacterial community composition in the digestive system of this species, despite the microflora has important roles in digestion, nutrition, disease resistance, and immune response. The present study investigated the bacterial flora community in the esophagus and intestinal tract of wild R. venosa by 16S rRNA gene sequencing. The esophagus and intestine had 1175 and 526 unique operational taxonomic units, respectively, with 616 common to both tissues...

Animals are common hosts of mutualistic, commensal and pathogenic microorganisms. Blood-feeding parasites feed on a diet that is nutritionally unbalanced and thus often rely on symbionts to supplement essential nutrients. However, they are also of medical importance as they can be infected by pathogens such as bacteria, protists or viruses that take advantage of the blood-feeding nutritional strategy for own transmission. Since blood-feeding evolved multiple times independently in diverse animals, it showcases a gradient of host-microbe interactions...

Coexistence of humans with microorganisms is well known for a long time. Besides the association with infectious diseases, personal microbiota is important for human health, possibly for some non-infectious diseases. Colonization of the human body with appropriate microorganisms after delivery is essential for physiological immune system maturation and also has an influence on central nervous system development. The composition of the gut microbiota is affected by the mode of delivery, early life nutrition and last but not least by lifestyle and drug, especially antibiotics intake...

Ryu Okumura, Kiyoshi Takeda
Background: The intestine is inhabited by a tremendous number of microorganisms, which provide many benefits to nutrition, metabolism and immunity. Mucosal barriers by intestinal epithelial cells make it possible to maintain the symbiotic relationship between the gut microbiota and the host by separating them. Recent evidence indicates that mucosal barrier dysfunction contributes to the development of inflammatory bowel disease (IBD). In this review, we focus on the mechanisms by which mucosal barriers maintain gut homeostasis...
