In the present study, circulating proportions of CD8(+) T (Tc) cell subsets, including IL-17 (Tc17) and IL-10 (Tc10) producing cells, were assessed in relapsing-remitting MS (RRMS) patients and a possible effect of beta interferon (IFN-β), glatiramer acetate (GA), and vitamin D (VitD) on these cell subsets was investigated. We show that both Tc17 and Tc10 cell fractions are elevated in the circ...
Background: CD8+ cytotoxic T lymphocytes have been recently divided based on their cytokine expression profile. Objective: To evaluate the percentages of CD8+ lymphocytes and their effector subsets including Tc1, Tc2 and Tc17 in the tumor draining lymph nodes (TDLNs) of patients with breast cancer. Methods: Single cell suspensions were obtained from TDLNs of 42 patients with breast cancer. Stai...
Myasthenia gravis (MG) is an autoimmune disease mediated by auto-antibodies against the neuromuscular junction. The thymus has an important role in the pathogenesis of MG because most of the patients have thymic pathology and thymectomy (TE) can reduce the severity of the disease. In the present study, the frequency of Th17 and Tc17 cells were studied in MG patients (pre and 6 months post-TE) a...
Graft-versus-host disease (GVHD) as the predominant complication of allogeneic hematopoietic stem cell transplantation remains to be fully understood. It is known that the cytokines produced by allogeneic reactive effector CD4+ and CD8+ T cells are involved in GVHD. However, the regulation and coordination of IFN-γ-producing and IL-17-producing effector T cells remain unclear. The present study...
BACKGROUND Although recent studies indicate a crucial role for IL-17A and IL-22 producing T cells in the pathogenesis of psoriasis, limited information is available on their frequency and heterogeneity and their distribution in skin in situ. METHODOLOGY/PRINCIPAL FINDINGS By spectral imaging analysis of double-stained skin sections we demonstrated that IL-17 was mainly expressed by mast cells...
background: cd8+ cytotoxic t lymphocytes have been recently divided based on their cytokine expression profile. objective: to evaluate the percentages of cd8+ lymphocytes and their effector subsets including tc1, tc2 and tc17 in the tumor draining lymph nodes (tdlns) of patients with breast cancer. methods: single cell suspensions were obtained from tdlns of 42 patients with breast cancer. stai...
Recent evidence points to a pathogenic role for CD8+ cytotoxic T (Tc) cells in Multiple sclerosis (MS). Based on cytokine profile, Tc cells can be divided into different subsets: IFN-γ (Tc1), IL-4 (Tc2), IL-10 (Tc10), IL-17 (Tc17), IL-21 (Tc21), IL-22 (Tc22) and TNF-α producing cells. In this study we evaluated the frequency of Tc cell subsets and the serum level of Tc17 differentiation cytokin...
Introduction Selective enhancement (or activation) of the immune system by novel small molecules may be a potential therapeutic approach for the treatment of cancer. RORgt (Retinoic Acid Receptor-related orphan receptor) is the key transcription factor for the development of CD4 Th17 cells, CD8 Tc17 cells and IL-17 innate immune cells including gδ T cells. A member of the nuclear receptor super...
The role of Th17/Tc17 peripheral blood T cells in psoriasis and their positive therapeutic response.
It is known that NB-UVB therapy can suppress a broad range of immune cells, but the additional effect of bathing in geothermal seawater still remains unclear. To study the influence of treatment on the expression of circulating immune cells contributing to the pathogenesis of psoriasis, six patients with psoriasis were treated with bathing in geothermal seawater two times daily combined with NB...
BACKGROUND CD8(+) cytotoxic T lymphocytes (CTLs) are crucial for eliminating hepatitis B virus (HBV) infected cells. DNA vaccination, a novel therapeutic strategy for chronic virus infection, has been shown to induce CTL responses. However, accumulated data have shown that CTLs could not be effectively induced by HBV DNA vaccination. METHODOLOGY/PRINCIPAL FINDINGS Here, we report that praziqu...
