Vitamin effects on the immune system: vitamins A and D take centre stage
Abstract
Vitamins are essential constituents of our diet that have long been known to influence the immune system. Vitamins A and D have received particular attention in recent years as these vitamins have been shown to have an unexpected and crucial effect on the immune response. We present and discuss our current understanding of the essential roles of vitamins in modulating a broad range of immune processes, such as lymphocyte activation and proliferation, T-helper-cell differentiation, tissuespecific lymp...

Role of Vitamin A in the Immune System
Abstract: Vitamin A (VitA) is a micronutrient that is crucial for maintaining vision, promoting growth and development, and protecting epithelium and mucus integrity in the body. VitA is known as an anti-inflammation vitamin because of its critical role in enhancing immune function. VitA is involved in the development of the immune system and plays regulatory roles in cellular immune responses and humoral immune processes. VitA has demonstrated a therapeutic effect in the treatment of various infectious diseases. To better understand the relati...

Influência da nutrição sobre o sistema imune intestinal
Resumo
Há muito tempo o intestino deixou de ser reconhecido apenas como um órgão de digestão e absorção para assumir seu importante papel imunológico. A função imune do intestino depende de três componentes: barreira intestinal, sistema imune associado ao tecido linfóide (GALT, plasmócitos, linfócitos, imunoglobulina A) e microflora intestinal. O objetivo da presente revisão bibliográfica é apresentar como a nutrição pode influenciar o sistema imune intestinal, destacando a participação de nutrientes ...

Prospective study of probiotic supplementation results in immune stimulation and improvement of upper respiratory infection rate
a b s t r a c t
The human gut microbiota is an important environmental factor for human health with evolutionarily conserved roles in immunity, metabolism, development, and behavior of the host. Probiotic organisms are claimed to offer several functional properties including stimulation of immune system. The purpose of this study is to investigate the effects of a probiotic supplementation on adult volunteers who have contracted the common cold four or more ...

Probiotics and immune health
Abstract
Purpose of review—The beneficial effects of probiotics have been demonstrated in many diseases. One of the major mechanisms of probiotic action is through the regulation of host immune response. This review highlights the recent scientific research findings that advance our understanding of probiotic regulation of the host immune response with potential application for disease prevention and treatment.
Recent findings—Probiotic genomic and proteomic studies have identified several genes and specific compounds derived from probiotics, which ...

Glutamine: Metabolism and Immune Function, Supplementation and Clinical Translation
Abstract: Glutamine is the most abundant and versatile amino acid in the body. In health and disease, the rate of glutamine consumption by immune cells is similar or greater than glucose. For instance, in vitro and in vivo studies have determined that glutamine is an essential nutrient for lymphocyte proliferation and cytokine production, macrophage phagocytic plus secretory activities, and neutrophil bacterial killing. Glutamine release to the circulation and availability is mainly controlled by key ...

Effects of Vitamin A Supplementation on Immune Responses and Correlation with Clinical Outcomes
INTRODUCTION
The term vitamin A designates a group of retinoid compounds with the biologic activity of all-trans-retinol. Retinoids
usually consist of four isoprenoid units with five conjugated carbon-carbon double bonds (141). Preformed vitamin A can be obtained mostly from dietary animal sources (liver, fish liver oils, eggs, and dairy products) as retinyl palmitate, whereas carotenoids that can be converted into retinol are obtained from vegetable foodstuffs (dark-green leafy ...

RELAÇÃO DO CONSUMO DE VITAMINAS E MINERAIS COM O SISTEMA IMUNITÁRIO: UMA BREVE REVISÃO
RESUMO:
O sistema imunitário é o sistema de defesa do corpo humano, e é constituído por uma complexa rede de células e moléculas dispersas por todo o organismo. Este sistema tem importante relação com a nutrição pois há interação entre a ingestão adequada de nutrientes, o aumento no estresse oxidativo e a ocorrência de processos infecciosos, com depleção imunitária. Esse artigo trata-se de revisão de literatura colocando em destaque os principais nutrientes que agem em benefício ...
