Atopic Dermatitis Whole Blood

Atopic Dermatitis Whole Blood for Allergy and Type 2 Inflammation Research

Atopic Dermatitis Whole Blood is collected from IRB-consented donors with a clinically confirmed atopic dermatitis diagnosis and shipped same day to preserve cellular and plasma analytes. Atopic dermatitis (eczema) is a chronic, relapsing inflammatory skin disease driven by type 2 immune activation together with epidermal barrier dysfunction. It is an allergic-type inflammatory condition rather than an autoimmune one, and these fresh samples support dermatology, allergy and biologic therapy research.

Type 2 Immune Activation and Barrier Dysfunction

  • The dominant immune axis is type 2: IL-4 and IL-13 signalling drives class switching to IgE, eosinophil recruitment and the itch–scratch cycle, and blockade of this axis is the basis of current biologic therapy.
  • IL-31 is a principal pruritogenic cytokine in atopic dermatitis and links type 2 inflammation directly to the itch that defines the patient experience.
  • Epidermal barrier dysfunction is a co-primary mechanism. Loss-of-function variants in FLG, which encodes filaggrin, are the best-established genetic risk factor and permit increased allergen and irritant penetration.
  • Total and allergen-specific IgE are commonly elevated, and peripheral blood eosinophil counts frequently track with disease activity — both accessible from whole blood.
  • Atopic dermatitis is typically part of the broader atopic march, co-occurring with asthma, allergic rhinitis and food allergy, so atopic comorbidity metadata supports cross-condition research.
  • Whole blood retains eosinophils, basophils, T cells and the IgE-containing plasma fraction in native proportions, allowing paired cellular and serological analysis from a single draw — something acellular matrices cannot provide.
