Background: Systemic lupus erythematosus (SLE) is an autoimmune disease that is characterized by T-cells imbalance. There are ongoing controversies about the role of specific T-helper cell subsets and their cytokines. The study aimed to confirm the disturbance of Th17/Treg ratio in SLE patients. Methods: Subjects were SLE patients who met the American College of Rheumatology 1997 criteria. Dis...

Fuzheng Fangai pill (FZFA), a traditional Chinese formula, is widely used for cancer treatment. Compared with other anticancer drugs, it is characterized by moderate and persistent efficacy with few side effects. The present paper emphasizes antitumor effect of FZFA combined with cyclophosphamide (CTX) on C57BL/6 mice subcutaneously injected with Lewis lung cancer cells, Comparing it with that ...

Hemopexin (Hx) is an acute-phase protein synthesized by hepatocytes in response to the proinflammatory cytokines IL-6, IL-1β, and TNF-α. Hx is the plasma protein with the highest binding affinity to heme and controls heme-iron availability in tissues and also in T lymphocytes, where it modulates their responsiveness to IFN-γ. Recent data have questioned regarding an anti-inflammatory role of Hx...

AIDS, caused by the retrovirus human immunodeficiency virus (HIV), is the leading cause of death of economically active people (age, 15-59 years) in sub-Saharan Africa. The host genetic variability of immune response to HIV and immune reconstitution following initiation of highly active antiretroviral therapy (HAART) is poorly understood. Here we focused on copy number variation of the β-defens...

Lymphocyte subpopulations producing cytokines and exerting regulatory functions represent key immune elements. Given their reciprocal interdependency lymphocyte subpopulations are usually assayed as diagnostic panels, rather than single biomarkers for specialist clinical use. This retrospective analysis on lymphocyte subpopulations, analyzed over the last few years in an outpatient laboratory i...

RAR-related orphan receptor gamma RORγT, a tissue-specific isoform of the RORC gene, plays a critical role in the development of naive CD4+ cells into fully differentiated Th17 lymphocytes. Th17 lymphocytes are part of the host defense against numerous pathogens and are also involved in the pathogenesis of inflammatory diseases, including autoimmune disorders. In this study, we functionally exa...

This study aimed to measure the synthesis of Th1 and Th2 cytokines by mononuclear cells after culture with live T. gondii and identified Th17 (CD4(+)) and Tc17 (CD8(+)) cells in toxoplasma-seronegative and toxoplasma-seropositive parturient and nonpregnant women. Cytometric bead arrays were used to measure cytokine levels (IL-2, TNF-α, IFN-γ, IL-4, IL-5, and IL-10); immunophenotyping was used t...

Th17 is a newly identified lineage of effector T cells involved in autoimmunity and immune responses to pathogens. We demonstrate in this study the pathogenic role of IL-17-producing CD4(+) T lymphocytes in allergic contact dermatitis (ACD) to skin-applied chemicals. IL-17(+) T cells infiltrate ACD reactions and predominantly distribute at the site of heavy spongiosis. Skin IL-17(+) T cells wer...

Purpose. To investigate the effect of 2-Methoxyestradiol (2ME2) on experimental autoimmune uveitis (EAU) and the mechanism. Method. C57BL/6 male mice were used to establish the EAU model. 2ME2 was abdominal administrated in D0-D13, D0-D6, and D7-D13 and control group was given vehicle from D0-D13. At D14, pathological severity was scored. Lymphocyte reaction was measured using MTT assay. T cell...

We described and analyzed the pathogenic difference between Good syndrome (GS) and oral lichen planus (OLP) in oral mucosa. Good syndrome (GS) is a rare disease characterized by B and T cell immunodeficiency associated with hypogammaglobulinemia and thymoma. GS patients frequently develop oral lichenoid lesions with lymphocytic infiltration beneath the basal layer. Oral lichen planus (OLP) is a...
