The intestinal mucosa contains a subset of lymphocytes that produce Th2 cytokines, yet the signals responsible for the recruitment of these cells are poorly understood. Macrophage-derived chemokine (MDC/CCL22) is a recently described CC chemokine known to chemoattract the Th2 cytokine producing cells that express the receptor CCR4. The studies herein demonstrate the constitutive production of M...
Increasing evidence suggests that the development of pulmonary fibrosis is a Th2-mediated process. We hypothesized that the CC chemokines that are associated with a Th2 profile (CCL17 and CCL22) have an important role in the development of pulmonary fibrosis. We measured CCL17 and CCL22 during the pathogenesis of bleomycin-induced pulmonary fibrosis. We found that both CCL17 and CCL22 were sign...
زمینه و هدف: بیماری تروفوبلاستیک حاملگی یکی از عوارض دوران بارداری است که دارای زیرگروه های مختلف شامل مول کامل، مول ناقص و کوریوکارسینوما می باشد. عامل مشتق شده از ماکروفاژها یا ccl22 ، جزء خانواده کموکاین ها می باشد که توسط ماکروفاژها، سلول های دندریتیکی و سلول های توموری تولید شده و نقش مهمّی در فراخوانی لنفوسیت های t تنظیمی و لنفوسیت های t helper2 به محل تومور دارد. ژن این کموکاین دارای چندی...
Abstract The immunoregulatory chemokine CCL22 is mainly secreted by dendritic cells (DC) in lymph nodes and plays a crucial role maintaining the balance between immune tolerance efficient response induction of intercellular contacts DC regulatory T (Treg) expressing only so far known receptor CCR4. In absence CCL22, to vaccination cancer has been proven be enhanced. this work, we aimed understa...
Background: An association between lung cancer and chemokines has been advocated in the recent years. This study aims at investigating the association between lung cancer and 16C/A single nucleotide polymorphism (SNP) (rs. 4359426) in C-C motif chemokine 22 (CCL22) as well as C1014T SNP (rs. 2228428) in C-C chemokine receptor type 4 (CCR4), which serves as the receptor for CCL22.Methods: Genoty...
Adult T cell leukemia is a mature CD4+ T cell malignancy which predominantly expresses CCR4 and is etiologically associated with human T cell leukemia virus type 1 (HTLV-1). Because HTLV-1 transmission depends on close cell-cell contacts, HTLV-1-infected T cells may preferentially interact with CCR4+CD4+ T cells for efficient viral transmission. In terms of gene expression and protein secretion...
BACKGROUND CC chemokine ligand 17 (CCL17) and CCL22 are the functional ligands for CCR4. We previously reported that inhibitors of nuclear factor-kappa B and p38 mitogen-activated protein kinase (p38 MAPK), but not of extracellular signal-related kinase (ERK), inhibited tumor necrosis factor (TNF)-α- and interferon (IFN)-γ-induced production of CCL17 by the human keratinocyte cell line, HaCaT. ...
Objective: To explore the mechanism by which macrophages secrete CCL22 to promote metastasis of triple-negative breast cancer under hypoxic conditions. Methods: 20 ng/mL mass concentration phorbol 12-myristate 13-acetate (PMA) cell culture medium, 4?,6-diamidino-2-phenylindole (DAPI), dimethyl sulfoxide (DMSO), trypsin digestion solution, CCL18 Kit , Interleukin (IL)-10 Kit, CCL17 TRIzolTM Reag...
The chemokine CCL22 is abundantly expressed in many types of cancer and is instrumental for intratumoral recruitment of regulatory T cells (Treg), an important subset of immunosuppressive and tumor-promoting lymphocytes. In this study, we offer evidence for a generalized strategy to blunt Treg activity that can limit immune escape and promote tumor rejection. Activation of innate immunity with ...
We recently reported that human T-lymphotropic virus type 1 (HTLV-1) infection is accompanied by a high frequency of CD4(+)FoxP3(+) cells in the circulation. In asymptomatic carriers of HTLV-1 and in patients with HTLV-1-associated inflammatory and malignant diseases, a high FoxP3(+) cell frequency correlated with inefficient cytotoxic T cell-mediated killing of HTLV-1-infected cells. In adult ...
