Human Vitiligo Peripheral Blood Mononuclear Cells

Description

Human Vitiligo Peripheral Blood Mononuclear Cells (PBMCs) are isolated from the peripheral blood of patients with clinically confirmed vitiligo, an autoimmune disorder characterized by melanocyte destruction and progressive skin depigmentation. These human-derived PBMCs contain immune cell populations (CD8⁺ cytotoxic T cells, autoreactive CD4⁺ T cells, B cells, and monocytes) that exhibit disease-specific immune activation, including elevated melanocyte-specific cytotoxic T lymphocytes and increased production of IFN-γ and TNF-α. The cells display typical mononuclear morphology with intact surface markers and demonstrate heightened reactivity to melanocyte antigens, reflecting the autoimmune pathogenesis of vitiligo. These PBMCs are particularly valuable for studying the complex interplay between innate and adaptive immunity in melanocyte destruction, including the role of oxidative stress in triggering autoimmunity. These vitiligo cells, derived from human vitiligo patients, can be compared with animal vitiligo models or non-human primate models of vitiligo to advance translational studies of disease mechanisms and potential immunotherapeutic interventions.
