Peripheral blood mononuclear cells (PBMC) from human immunodeficiency virus (HIV)-infected patients, asymptomatic or with acquired immunodeficiency virus, produced 10-fold less interleukin 12 (IL-12) free heavy chain and fivefold less biologically active IL-12 heterodimer than PBMC from uninfected healthy donors when challenged in vitro with the common human pathogen Staphylococcus aureus. In c...
The loss of immune function following infection with human immunodeficiency virus (HIV) may result from altered production of immunoregulatory cytokines such as interleukin-10 (IL-10) and IL-12. In this study, we analyzed IL-10 and IL-12 production by mitogen-stimulated peripheral blood mononuclear cells (PBMC) from HIV+ individuals and correlated their levels with proliferative responses to th...
ABSTRACT Introduction: HIV/AIDS is considered one of the great cases public health, but it seen that patients who use antiretroviral therapy (ART) and practice strength training promote a promotion their health. Objectives: Assess impact resistance on cytokines body composition in people living with HIV/AIDS. Methods: Randomized clinical trial, sample consisted 12 patients, 7 from Strength Grou...
To document the in vivo interactions occurring between the immune system and HIV replicating cells, we analyzed using in situ hybridization the production of IL-1 beta, IL-6, IL-2, and INF-gamma in eight hyperplastic lymph nodes from HIV-1 infected patients. Numerous IL-1 beta- and IL-6-producing cells associated in clusters were detected in sinuses. Few individual IL-1 beta- and IL-6-producing...
Murine models indicate that interleukin-10 (IL-10) can suppress viral clearance, and interventional blockade of IL-10 activity has been proposed to enhance immunity in chronic viral infections. Increased IL-10 levels have been observed during HIV infection and IL-10 blockade has been shown to enhance T-cell function in some HIV-infected subjects. However, the categories of individuals in whom t...
A rare subset of IL-10-producing B cells, named regulatory B cells (Bregs), suppresses adaptive immune responses and inflammation in mice. In this study, we examined the role of IL-10-producing B cells in HIV-1 infection. Compared to uninfected controls, IL-10-producing B cell frequencies were elevated in both blood and sigmoid colon during the early and chronic phase of untreated HIV-1 infecti...
Monocyte-derived macrophages (MDM) can polarize into different subsets depending on the environment and the activation signal to which they are submitted. Differentiation into macrophages allows HIV-1 strains to infect cells of the monocytic lineage. In this study, we show that culture of monocytes with a combination of IL-12 and IL-18 led to macrophage differentiation that was resistant to HIV...
زمینه و هدف: اسکلروز متعدد (multiple sclerosis, ms) یک بیماری خود ایمن توام با اختلال در سیستم اعصاب مرکزی می باشد که ماکروفاژها و سلول های دندریتیک نقش مهمی در تعدیل یا پیشرفت این بیماری ایفا می کنند. تاثیر عصاره قارچ در بلوغ سلول های دندریتیک مشتق از مونوسیت و تعدیل پاسخ لنفوسیت های t را در حضور پروتیین بازی میلین (myelin basic protein, mbp) که به عنوان مدل آزمایشگاهی اسکلروز متعدد در نظر گرف...
IL-27, a member of the IL-12 family of cytokines, plays an important and diverse role in the function of the immune system. Whilst generally recognized as an anti-inflammatory cytokine, in addition IL-27 has been found to have broad anti-viral effects. Recently, IL-27 has been shown to be a potent inhibitor of HIV-1 infection in CD4+ T cells and macrophages. The main objective of this study was...
The immunoregulatory cytokine interleukin 6 (IL-6) directly upregulates production of human immunodeficiency virus (HIV) in acutely as well as in chronically infected cells of monocytic lineage. In addition, IL-6 synergizes with tumor necrosis factor alpha (TNF-alpha) in the induction of latent HIV expression. Unlike TNF-alpha, upregulation of viral expression induced by IL-6 alone does not occ...
