One of the studies on RNA samples from eosinophils of individuals with atopic dermatitis, atopy, allergic rhinitis, and asthma identified 18 miRNAs (miR-1276, miR-29B2, miR-3175, miR-33B, miR-4308, miR-4523, miR-4673, miR-4785, miR-590, miR-638, miR-614, miR-142, miR-3064, miR-4434, miR-1304, miR-2355, miR-26A2, and miR-645) differentially expressed in eosinophil samples in cases of atopic dermatitis or asthma, or according to PC20 or IgE levels, compared to healthy samples [11]. The gene discussed is IGHE; the disease is atopic eczema.
