Human Allergy-related Peripheral Blood Mononuclear Cells

Description

Human Allergy-related Peripheral Blood Mononuclear Cells (PBMCs) are isolated from the peripheral blood of patients with clinically confirmed allergic disorders, including atopic dermatitis, allergic asthma, and food allergies. These human-derived PBMCs contain immune cell populations (Th2-skewed T cells, B cells, and monocytes) that exhibit allergy-specific immune activation, including elevated IgE production, increased IL-4/IL-5/IL-13 cytokine secretion, and enhanced expression of activation markers (such as CD203c and FcεRI on IgE-associated immune pathways). The cells display typical mononuclear morphology with intact surface markers and demonstrate hyperresponsiveness to allergen stimulation, reflecting the Th2-dominant immune polarization characteristic of allergic diseases. These PBMCs are particularly valuable for studying the mechanisms of IgE-mediated hypersensitivity reactions and the development of novel immunotherapies for allergic conditions. In addition, these PBMCs enable analysis of low-frequency immune subsets involved in severe or treatment-resistant allergic responses, enabling more precise modeling of patient-specific hypersensitivity mechanisms.
