RATIONALE Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal lung disease. While it has been suggested that T cells may contribute to IPF pathogenesis, these studies have focused primarily on T cells outside of the pulmonary interstitium. Thus, the role of T cells in the diseased lung tissue remains unclear. OBJECTIVE To identify whether specific CD4+ T cell subsets are differentiall...
BACKGROUND Atopic dermatitis (AD) and psoriasis represent polar immune diseases. AD is a T(H)2/T(H)22-dominant disease, whereas psoriasis is considered a T(H)1/T(H)17 disease. Local immune deviation is suggested to be regulated by dendritic cell (DC)-induced T-cell polarization and recruitment of specific T-cell subsets by chemokines. Although the role of chemokines is well documented, the actu...
Decreased CD4(+) T cell counts are the best marker of disease progression during HIV infection. However, CD4(+) T cells are heterogeneous in phenotype and function, and it is unknown how preferential depletion of specific CD4(+) T cell subsets influences disease severity. CD4(+) T cells can be classified into three subsets by the expression of receptors for two T cell-tropic cytokines, IL-2 (CD...
Background and purpose: The aim of this study was to compare the proportion of natural killer (NK) and natural killer T (NKT)-like cells in dyspeptic disorders caused by Helicobacter pylori (H. pylori). Materials and methods: In a case-control study, 27 patients with gastric cancer (GC), 25 patients with peptic ulcer (PUD), and 22 patients with non-ulcer dyspepsia (NUD) were enrolled. After en...
