Special Issue Information

Dear Colleagues,

The global prevalence of food allergies (FA) has grown dramatically in recent years. The development of FA is directly related to several events and lifestyle changes that affect the gut microbiota composition and other factors, such as cesarean, antibiotic intake prenatally or perinatally, and gastric acidity inhibitors intake, which increase the risk of FA. Commensal diversity is a requirement for the maintenance of host homeostasis in the gut. To maintain ecological diversity and to avoid bacterial overgrowth, the immune system of the host must be regulated. It has been elucidated that a specific microbial consortium is responsive of tolerance to foods. On the other hand, dysbiosis in the gut is involved in inflammation, leading to pathogenesis and food allergy development. More studies are needed for a better understanding the causal relationships between microbiota, host, environment, and food allergy outcomes. The real role of other factors such as nutrition on the bacterial metabolome, and most importantly, on the mucosal immune responses, need to be re-evaluated. Recent successes in advanced molecular methodologies based on -omics technologies (i.e., proteomics, genomics, metabolomics) and systems biology approaches make them favorable strategies to analyze the relationship between gut microbiome and food allergies outcomes. In addition, future directions and new perspectives of omics-based systems biology approaches performed for the study of the mechanisms of food allergies and microbiome association will be described in this Special Issue.

  • Microorganisms and food allergies, and their implication in immune responses
  • Biomarker identification of FA progression
  • Proteomics, Genomics and Metabolomics for the study of FA and microbiome relations
  • Omics approaches/ Characterization of bacteria metabolites and their role in FA
  • Antibiotic treatments and their potential implication in the development of food allergies
  • Microbial transplant as a treatment to recover food allergies
  • Probiotics and food dietary recommendations for food allergy patients

Cow’s milk allergy (CMA) is one of the most prevalent food allergies in children. Several studies have demonstrated that gut microbiota influences the acquisition of oral tolerance to food antigens at initial stages of life. Changes in the gut microbiota composition and/or functionality (i.e., dysbiosis) have been linked to inadequate immune system regulation and the emergence of pathologies. Moreover, omic sciences have become an essential tool for the analysis of the gut microbiota. On the other hand, the use of fecal biomarkers for the diagnosis of CMA has recently been reviewed, with fecal calprotectin, α-1 antitrypsin, and lactoferrin being the most relevant. This study aimed at evaluating functional changes in the gut microbiota in the feces of cow’s milk allergic infants (AI) compared to control infants (CI) by metagenomic shotgun sequencing and at correlating these findings with the levels of fecal biomarkers (α-1 antitrypsin, lactoferrin, and calprotectin) by an integrative approach. We have observed differences between AI and CI groups in terms of fecal protein levels and metagenomic analysis. Our findings suggest that AI have altered glycerophospholipid metabolism as well as higher levels of lactoferrin and calprotectin that could be explained by their allergic status. Full article

Food allergies (FA) have dramatically increased in recent years, particularly in developed countries. It is currently well-established that food tolerance requires the strict maintenance of a specific microbial consortium in the gastrointestinal (GI) tract microbiome as alterations in the gut microbiota can lead to dysbiosis, causing inflammation and pathogenic intestinal conditions that result in the development of FA. Although there is currently not enough knowledge to fully understand how the interactions between gut microbiota, host responses and the environment cause food allergies, recent advances in ‘-omics’ technologies (i.e., proteomics, genomics, metabolomics) and in approaches involving systems biology suggest future headways that would finally allow the scientific understanding of the relationship between gut microbiome and FA. This review summarizes the current knowledge in the field of FA and insights into the future advances that will be achieved by applying proteomic techniques to study the GI tract microbiome in the field of FA and their medical treatment. Metaproteomics, a proteomics experimental approach of great interest in the study of GI tract microbiota, aims to analyze and identify all the proteins in complex environmental microbial communities; with shotgun proteomics, which uses liquid chromatography (LC) for separation and tandem mass spectrometry (MS/MS) for analysis, as it is the most promising technique in this field.

The microbiota present in the gastrointestinal tract is involved in the development or prevention of food allergies and autoimmune disorders; these bacteria can enter the gallbladder and, depending on the species involved, can either be benign or cause significant diseases. Occlusion of the gallbladder, usually due to the presence of calculi blocking the bile duct, facilitates microbial infection and inflammation, which can be serious enough to require life-saving surgery. In addition, the biliary salts are secreted into the intestine and can affect the gut microbiota. The interaction between the gut microbiota, pathogenic organisms, and the human immune system can create intestinal dysbiosis, generating a variety of syndromes including the development of food allergies and autoimmune disorders. The intestinal microbiota can aggravate certain food allergies, which become severe when the integrity of the intestinal barrier is affected, allowing bacteria, or their metabolites, to cross the intestinal barrier and invade the bloodstream, affecting distal body organs. This article deals with health conditions and severe diseases that are either influenced by the gut flora or caused by gallbladder obstruction and inflammation, as well as putative treatments for those illnesses.
