Abstract :

In recent years, it is recognized that acquired immunity is controlled by regulatory T cell (T-reg). Since fundamental pathophysiological changes of allergy are mainly caused by hyper-responsiveness of immune system to allergens that acquire after birth, T-regs likely play key roles in the pathogenesis of allergy, particularly during the sensitization phase. However, accumulated information indicate that there are several distinctive subtypes of T-regs in man and each of them seems to play a different role in controlling immune system, which complicates the involvement of T-regs in allergy. The aim of the present study is to attempt to classify subtypes of T-regs and summarize their roles in allergy. T-regs should include natural Tregs (nT-reg) including inducible co-stimulator (ICOS)(+) T-regs, inducible/adaptive T-regs (iT-reg), interleukin (IL)-10-producing type 1 T-regs (Tr1 cells), CD8(+) T-regs and IL-17-producing T-regs. These cells share some common features including expression of Foxp3 (except for Tr1 cells), and secretion of inhibitory cytokine IL-10 and/or TGF-�?². Furthermore, it is noticeable that T-regs likely contribute to allergic disorders such as dermatitis and airway inflammation and play a crucial role in the treatment of allergy through their actions on suppression of effector T cells and inhibition of activation of mast cells and basophils. Modulation of functions of T-regs may provide a novel strategy to prevent and treat allergic diseases.
