Severity of atopic dermatitis and Ascaris lumbricoides infection: an evaluation of CCR4+ and CXCR3+ helper T cell frequency.
INTRODUCTION Ascaris lumbricoides-infected patients present lower prevalence of severe atopic dermatitis. METHODS Peripheral blood of infected children with atopic dermatitis was assessed by flow cytometry of the frequency of Th1 and Th2 cells through the expression of CXCR3 and CCR4 chemokine receptors, respectively. RESULTS Helminth-free patients with atopic dermatitis presented a high fr...
متن کاملPercutaneous application of peptidoglycan from Staphylococcus aureus induces infiltration of CCR4+ cells into mouse skin.
BACKGROUND The lesional skin of patients with atopic dermatitis has an increased number of type 2 helper T (TH2) cells in the dermis and is superficially colonized by Staphylococcus aureus. The purpose of this study was to determine the effects of peptidoglycan (PEG) from S aureus on TH2 cell induction in murine skin. METHODS Mice were sensitized with house dust mite antigen (MA) by topical a...
متن کاملTemporal dynamic changes of phenotypic expression of peripheral CD4 cells during environmental allergen challenge in an experimental model of canine atopic dermatitis: a pilot study.
The immunopathology behind atopic dermatitis (AD) involves a myriad of inflammatory cells and their mediators. Thymus and activation-regulated chemokine (TARC) plays a significant role in the inflammatory phase by recruiting CCR4(+) T(H)2 cells. In addition, CD25(+) activated T cells further propagate the allergic response after sensitization by producing cytokines. The purpose of this pilot st...
متن کاملPathogenesis of Atopic Dermatitis: Current Paradigm
Atopic dermatitis (AD) is characterized by skin inflammation, barrier dysfunction and chronic pruritus. In this review, recent advances in the pathogenesis of AD are summarized. Clinical efficacy of the anti-IL-4 receptor antibody dupilumab implies that type 2 cytokines IL-4 and IL-13 have pivotal roles in atopic inflammation. The expression of IL-4 and IL-13 as well as type 2 chemokines such a...
متن کاملPreferential expression of T(h)2-type chemokine and its receptor in atopic dermatitis.
Lesional skin of patients with atopic dermatitis (AD) is histologically characterized by hypertrophy of the skin, and the infiltration of a large number of eosinophils and T cells into the dermis. Recent studies have indicated that Th2 cells play a crucial role in the pathogenesis of AD skin. Chemokines and their receptors are implicated in the development of symptoms of various skin diseases s...
