New Thoughts: Food Sensitivity Originates From Food Quality Detecting

摘要

DESCRIPTION In a new issue of Cell, Florsheim et al. proposed another worldview for food sensitivity: We recommend that the insusceptible framework (explicitly, type 2 or hypersensitive invulnerability) partakes in food quality control by checking food synthesis and utilizing dietary proteins as prompts related with food quality. Net positive quality brings about invulnerable resistance toward dietary antigens, while net negative worth outcomes in hypersensitive refinement by means of acceptance of antigen-explicit IgE antibodies. This is situated to some degree on the possibility that hypersensitivity is a framework for ejection of poisons. The creators contend that the net negative worth of food allergens originates from allergens being intrinsically poisonous or then again being truly connected with harmful substances. Allergens can genuinely connect with an assortment of atoms going from lipopolysaccharide to metals, and these related particles can advance either sensitivity or resistance. RothWalter et al. as of late exhibited that iron bound to the milk protein b-lacto globulin advanced resilience through initiation of the aryl hydrocarbon receptor, while the allergen without iron as freight drove allergy. Food proteins may likewise straightforwardly actuate the intrinsic invulnerable framework, as Ruiter et al. as of late exhibited with nut, which actuated human dendritic cells through Toll-like receptor 1/2 heterodimers to drive type 2 immunity. Florsheim et al. proposed that allergens that are protease inhibitors and may hence meddle with stomach related catalysts would be net negative proteins because of adverse impacts on the host. Sullivan et al. have as of late shown that supplement detecting, explicitly, starch detecting, can modify epithelial cell aggregate and capacity through the activity of gd T cells. This fascinating work straightforwardly ties supplement content to the situation with the mucosal safe framework.
