Artigo Científico – Teste Atopico para diagnostico de alergia alimentar em crianças

Background: In recent years, food allergy, especially in the child population, has become an increasing problem in developed societies. In the youngest children, it is a frequent cause of gastrointestinal disorders. The atopy patch test, applied from several years in clinical practice, is one of the methods used in allergology. Objectives: The objective of the work was an assessment of the diagnostic value of the atopy patch test in the diagnosis of allergy to cow’s milk protein and to wheat proteins in children with gastrointestinal symptoms. Material and Methods: The study was ...

Artigo Científico – Papel da microbiota intestinal na SII WJG

Abstract: Irritable bowel syndrome (IBS) is the most prevalent functional gastrointestinal disorder. It is a multifactorial disorder. Intestinal microbiota may cause the pathogenesis of IBS by contributing to abnormal gastrointestinal motility, low-grade inflammation, visceral hypersensitivity, communication in the gut-brain axis, and so on. Previous attempts to identify the intestinal microbiota composition in IBS patients have yielded inconsistent and occasionally contradictory results. This inconsistency may be due to the differences in the molecular techniques employed, the ...

Artigo Científico – Microbiota intestinal, diabetes e probioticos

Abstract: Diabetes is a condition of multifactorial origin, involving several molecular mechanisms related to the intestinal microbiota for its development. In type 2 diabetes, receptor activation and recognition by microorganisms from the intestinal lumen may trigger inflammatory responses, inducing the phosphorylation of serine residues in insulin receptor substrate-1, reducing insulin sensitivity. In type 1 diabetes, the lowered expression of adhesion proteins within the intestinal epithelium favours a greater immune response that may result in destruction of pancreatic β cells by ...

Artigo Científico – Microbiota intestinal e risco cardiometabolico

ABSTRACT: The gut microbiota obtained after birth is composed of a large range of bacteria that play different roles in the human host, such as nutrient uptake, protection against pathogens and immune modulation. The intestinal bacterial content is not completely known, but it is influenced by internal, and mainly by external factors, which modulate its composition and function. Studies indicate that the gut microbiota differs in lean and obese individuals, and in individuals with different food habits. There is evidence that the relationship between diet, inflammation, insulin resis...

Artigo Científico – Mecanismo de diferenciação das celulas M

Intestinal M (microfold or membranous) cells are an enigmatic lineage of intestinal epithelial cells that initiate mucosal immune responses through the uptake and transcytosis of luminal antigens. Due to their rarity, the mechanisms of M-cell function and differentiation are poorly understood. To overcome this problem, experimental strategies to enrich for M-cells have been established. Transcriptome analyses have provided valuable insight, especially on the receptors for antigen uptake, and such studies have broadened our knowledge of M-cell function. In another line of investigation, ...

Artigo Científico – Intervenções Alimentares e prevenção de alergia

Abstract: The incidence of atopic diseases such as asthma, atopic dermatitis and food allergies has increased exponentially in recent decades. Although atopic diseases have a clear genetic basis, environmental factors such as the diet, seems to play an important role in its development. This article summarizes main studies exploring whether feeding practices of mothers and infants intervenes in the development of allergic diseases. The potential role of dietary practices of the mother and infants for the prevention and/or management of allergies in infants is discussed. The ...

Artigo Científico – Infecção e resposta da Microbiota

Abstract: Longitudinal studies of the microbiota are important for discovering changes in microbial communities that affect the host. The complexity of these ecosystems requires rigorous integrated experimental and computational methods to identify temporal signatures that promote physiologic or pathophysiologic responses in vivo. Employing a murine model of infectious colitis with the pathogen Citrobacter rodentium, we generated a 2-month time-series of 16S rDNA gene profiles, and quantitatively cultured commensals, from multiple intestinal sites in infected and uninfected mice. We ...

Artigo Científico – Imunidade Celular na alergia ao leite de vaca

Food allergy is an aberrant immune-mediated reaction against harmless food substances, such as cow’s milk proteins. Due to its very early introduction, cow’s milk allergy is one of the earliest and most common food allergies. For this reason cow’s milk allergy can be recognized as one of the first indications of an aberrant inflammatory response in early life. Classically, cow’s milk allergy, as is true for most other allergies as well, is primarily associated with abnormal humoral immune responses, that is, elevation of specific immunoglobulin E levels. There is growing evidence ...
