Identification of local Th2 and Th0 lymphocytes in vernal conjunctivitis by cytokine flow cytometry.

Abstract

In ocular allergic diseases, local lymphocytes expressed the Th2 phenotype and, to a lesser degree, the Th0 phenotype. Although results of systemic allergic markers can be inconclusive in patients with VKC, flow cytometry demonstrated a local lymphocyte phenotype that can account for the clinical and histologic abnormalities of VKC.
