=> les bactéries "Clostridia" aident dans la prévention des allergies des aliments. La réponse immunitaire est inversée une fois clostridia introduit dans les souris.The study,4, 5 which used mice, found that a common gut bacteria called Clostridia helps prevent sensitization to food allergens. In fact, immune responses to food allergens were reversed once Clostridia bacteria were put back into the mice.
=> Les bacteroides n'ont pas eu cet effet, suggérant que clostridia pourrait avoir un rôle unique.Another common type of gut bacteria, Bacteroides, did not have this effect, suggesting Clostridia may have a unique role in this regard.
=> Clostridia donne des instructions aux cellules immunes pour qu'elles produisent l'interleukine IL-22, qui est connue pour réduire la perméabilité intestinale du tissu endothélial.Using genetic analysis, the researchers determined that Clostridia instructs immune cells to produce a signaling molecule called interleukin-22 (IL-22), which is known to reduce the permeability of the lining in your intestines.
=> Exprimé autrement, cela aide dans la prévention du leaky gut (perméabilité intestinale) - une condition qui permet aux allergènes d'entrer dans la circulation sanguine, déclenchant alors une réponse immunitaire.In other words, it helps prevent leaky gut syndrome—a condition that allows allergens to enter your bloodstream, thereby producing an immune response. The researchers suggest this discovery may eventually lead to probiotic therapies to treat food allergies. As reported by HealthCanal.com:6

Gut bacteria that protect against food allergies identified
They found that the presence of Clostridia, a common class of gut bacteria, protects against food allergies. By inducing immune responses that prevent food allergens from entering the bloodstream, Clostridia minimize allergen exposure and prevent sensitization – a key step in the development of food allergies. The discovery points toward probiotic therapies for this so-far untreatable condition, they report today in the Proceedings of the National Academy of Sciences.
