On the other hand, ex vivo basophils from non‐allergic and peanut‐allergic subjects were only different regarding FcεRI expression, explained by the difference in concentration of circulating IgE, thereby arguing, that the effector cells of allergy may not display a diverse cellular molecular (and functional) profile besides carrying allergen‐specific IgE on their surface. This evidence concerns the gene IGHE and Allergy.
