Background: Generation of monocyte-derived dendritic cells (MDDC) is induced in the presence of GM-CSF and IL-4, and a maturation stimulus is added to the monocyte culture to obtain mature Dendritic Cells (DCs) suitable for therapy. TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effe...

Macrophages produce various cytokines in response to mycobacteria, including interleukin 10 (IL-10) and tumor necrosis factor alpha (TNF-alpha). IL-10 has been shown to down-regulate numerous macrophage functions, including microbicidal activity against intracellular bacteria and parasites. IL-10 also inhibits interferon-gamma (IFN-gamma) production and antigen-specific proliferation of Th1 cel...

The migration of epidermal Langerhans cells (LC) to lymph nodes (LN) is critical in the initiation of contact hypersensitivity (CHS) responses. Studies suggest that contact allergen-induced epidermal proinflammatory cytokines, including IL-1 and TNF-alpha, play important roles in promoting LC migration. Contact allergens also induce epidermal anti-inflammatory cytokines such as IL-10. Since IL-...

The changes of tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), interleukin-10 (IL-10) in the serum of Henoch-Schonlein purpura nephritis (HSPN) patients were analyzed to explore the correlation between the above inflammatory factors and progression of the disease. The present study used the double antibody sandwich enzyme-linked immunosorbent assay (ELISA) method to detect the serum leve...

Earlier, we demonstrated that the inhibition of nitric oxide synthase (NOS) by nitro-l-arginine methyl ester (l-NAME) infusion increases the endogenous production of proinflammatory cytokine, tumor necrosis factor (TNF-α). In the present study, we examined the hypothesis that inhibition of nitric oxide (NO) production leads to the suppression of interleukin (IL)-10 (anti-inflammatory cytokine) ...

Interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) are key anti- and pro-inflammatory mediators elicited during the host immune response to Mycobacterium tuberculosis (Mtb). Understanding the opposing effects of these mediators is difficult due to the complexity of processes acting across different spatial (molecular, cellular, and tissue) and temporal (seconds to years) scales. We take...

We have found reduced activity of tumor necrosis factor (TNF)-alpha accompanying resolving and fibrosing alveolitis induced in NMRI mice by mineral particles (MnO2 and SiO2, respectively), which is in apparent contradiction to the well-recognized proinflammatory and profibrotic activities of this cytokine. The objective of this study was to examine the mechanisms involved in this paradoxical re...

In the present study, we investigated the molecular mechanisms of spontaneous and tumor necrosis factor alpha (TNF-alpha)-mediated apoptosis of human polymorphonuclear neutrophils (PMN). Whereas TNF-alpha-mediated apoptosis was almost absent in the presence of the caspase-8 inhibitor Z-Ac-Ala-Glu-Val-Asp-7-fluoromethyl ketone (Z-AEVD-FMK), the inhibitor had no effect on spontaneous apoptosis, s...

background: immune system disturbances have an important role in endometriosis which may lead to infertility. it seems that inflammatory cytokines specially tumor necrosis factor alpha (tnf-) which were produced by activated macrophages have an important role in pathology of endometriosis. based on this theory, anti tnf- drugs like pentoxifylline (px) are suggested as new drugs for endometrio...
