Critical features of an in vitro intestinal absorption model to study the first key aspects underlying food allergen sensitization. Compr Rev Food Sci Food Saf 2023; 22:971-1005. [PMID: 36546415 DOI: 10.1111/1541-4337.13097] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 11/23/2022] [Accepted: 11/30/2022] [Indexed: 12/24/2022]
Abstract
New types of protein sources will enter our diet in a near future, reinforcing the need for a straightforward in vitro (cell-based) screening model to test and predict the safety of these novel proteins, in particular their potential risk for de novo allergic sensitization. The Adverse Outcome Pathway (AOP) for allergen sensitization describes the current knowledge of key events underlying the complex cellular interactions that proceed allergic food sensitization. Currently, there is no consensus on the in vitro model to study the intestinal translocation of proteins as well as the epithelial activation, which comprise the first molecular initiation events (ME1-3) and the first key event of the AOP, respectively. As members of INFOGEST, we have highlighted several critical features that should be considered for any proposed in vitro model to study epithelial protein transport in the context of allergic sensitization. In addition, we defined which intestinal cell types are indispensable in a consensus model of the first steps of the AOP, and which cell types are optional or desired when there is the possibility to create a more complex cell model. A model of these first key aspects of the AOP can be used to study the gut epithelial translocation behavior of known hypo- and hyperallergens, juxtaposed to the transport behavior of novel proteins as a first screen for risk management of dietary proteins. Indeed, this disquisition forms a basis for the development of a future consensus model of the allergic sensitization cascade, comprising also the other key events (KE2-5).

Comparison of digestibility and potential allergenicity of raw shrimp (Litopenaeus vannamei) extracts in static and dynamic digestion systems. Food Chem 2020; 345:128831. [PMID: 33326890 DOI: 10.1016/j.foodchem.2020.128831] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 11/10/2020] [Accepted: 12/03/2020] [Indexed: 11/23/2022]
Abstract
In this work, a simplified dynamic digestion system was developed, and used for comparing the digestibility and potential allergenicity of raw shrimp extracts (RSE) in static and dynamic digestion systems. Protein hydrolysis was analyzed by electrophoresis, and the potential allergenicity was reflected in IgG/IgE binding ability and activation of basophils. In comparison with static digestion, protein hydrolysis indicated different kinetic behaviors, especially tropomyosin (TM) showed better digestion stability during dynamic digestion. The potential allergenicity of RSE exhibited different changing trends with digestion in the two systems. However, the apparent molecular weight (Mw) of immune fragments (>11 kDa) showed good approximation, and the IgE-binding fragment near 70 kDa revealed outstanding digestion stability than primordial protein in both systems. In conclusion, the dynamic conditions had a significant impact on the assessment of the persistence and potential allergenicity of digestion-resistant allergens, while the apparent Mw of IgG/IgE binding hydrolysate was not affected.

Abstract
The major allergen of chum salmon (Oncorhynchus keta) roe is the β'-component (Onc k 5, β'-c), which is a yolk protein and a fragment of vitellogenin. When yolk content containing β'-c was orally administered to mice, β'-c passed through the gastrointestinal tract and was excreted in feces without marked degradation. The direct administration of β'-c to ligated jejunal and ileal loops showed that β'-c was absorbed through the small intestine and transferred into the blood. Immunohistochemical staining showed that orally administered β'-c was distributed from the apical side to the basal side of intestinal epithelial cells, suggesting that endocytosis may be involved in the intestinal absorption of β'-c. In conclusion, β'-c is absorbed along a large portion of the small intestine and circulates in the blood stream without significant digestion. The resistance of β'-c to gastrointestinal digestion seems to contribute to its strong allergenicity.

Abstract
Tropomyosins are defined as risk factors for shrimp allergy. However, their concentration in different preparations has not been clarified. We quantified the tropomyosin concentration in shrimp meat, which was cooked using several methods or was stored under various conditions. The results demonstrated that shrimp meat from various preparations and storage conditions maintained tropomyosin concentrations that were sufficient to cause food allergies.

Abstract
Shrimp are highly allergenic foods. Current management are limited to the avoidance of foods. Therefore, there is an unmet need for a safe and effective therapy using modified allergens. This study focuses on assessing the potential for modification of the allergenicity of shrimp proteins following heat treatment or simulated gastric digestion. Shrimp proteins do not reduce their IgE reactivity after heat treatment but it is reduced by simulated gastric digestion in a time- and dose-dependent manner. Tropomyosin in shrimp extract is worse digested than purified tropomyosin. After 60 min of 10 U/μg pepsin digestion, a strong inhibition was produced in the in vivo skin reactivity of shrimp extracts and in activation of basophils from allergic patients. Immunisation experiments performed in rabbits demonstrated that digested boiled shrimp extract is able to induce IgG antibodies that block the IgE binding to the untreated boiled shrimp extract in shrimp-allergic patients. Building on our observations, digestion treatment could be an effective method for reducing shrimp allergenicity while maintaining the immunogenicity.

Abstract
Food proteins were considered to be absorbed into the body after being digested to amino acids, dipeptides, and tripeptides. However, there are studies indicating that some proteins can pass through the intestinal epithelium under normal physiological conditions, perhaps not in sufficient quantities to be of nutritional importance, but in quantities that may be antigenically or biologically active. In the present study, rat intestinal lymph samples were collected using a modified lymph fistula rat model in fasting and cow's milk postprandial states. Low molecular weight proteins were enriched by ultrafiltration and differential solubilization, separated by 1D-SDS-PAGE, digested in-gel based on molecular weight, and identified using nano-LC-MS/MS. In the postprandial rat intestinal lymph, nine bovine-specific proteins (false discovery rate ≤1%) were identified in different molecular weight regions. Most proteins identified in lymph were highly abundant proteins in the milk, such as β-lactoglobulin and caseins. Seven of the nine identified bovine-specific proteins are allergens in milk. This strategy can be used to search for proteins that can enter the intestinal lymph and analyze their common features. Understanding the common features of these proteins might help to develop protein drugs taken orally, so that therapeutic proteins might embody fusion domains for cross-barrier transport or translocation.

Abstract
This work investigates the resistance to proteolysis and heating of the yellow mustard (Sinapis alba L.) allergens Sin a 1 (2S albumin), Sin a 3 (nonspecific lipid transfer protein, LTP), and Sin a 4 (profilin) to explain their potential capability to induce primary sensitization at the gastrointestinal level. Sin a 1 and Sin a 3 resisted gastric digestion showing no reduction of the IgE reactivity. Intestinal digestion of Sin a 1 and Sin a 3 produced a limited proteolysis but retained significant IgE-binding reactivity. Sin a 1 was stable after heating, and although Sin a 3 was modified, most of its structure was recovered after cooling back. These two allergens would be therefore able to sensitize by ingestion. Sin a 4 was completely digested by gastric treatment and its conformational structure markedly modified at 85 °C. Thus, this allergen can be described as a nonsensitizing mustard allergen.
