In the previous paper, it was shown that interleukin 2 (IL-2) enhanced NK cell activity against renal carcinoma cell lines and fresh solid tumor cells of renal cell carcinoma (RCC) which are not susceptible to NK cells, and that IL-2 in duced a higher cytotoxicity than interferon ƒÁ (IFN-ƒÁ). The present study was carried out to examine the mechanism of the en hanced cytotoxicity of IL-2 and IF...
Osteoarthritic chondrocytes secrete matrix metalloproteinase-13 (MMP-13) in response to interleukin-1 (IL-1), causing digestion of type II collagen in cartilage. Using chondrocytic cells, we previously determined that IL-1 induced a strong MMP-13 transcriptional response that requires p38 MAPK, JNK and the transcription factor NF-kappaB. Now, we have studied the tissue-specific transcriptional ...
Background: The levels of IL-13, IL-4, IL-1B, TNF-α and IL-10 alter in the colon of people with ulcerative colitis. previous studies, it was found that shilajit (asphaltum) was effective in the improvement of ulcerative colitis.we guessed that the shilajit has been able to improve the ulcerative colitis by affecting the amount of cytokines. Objective: The aim of the present study was to investi...
Cytokines have been shown to be powerful regulators of the immune response. In this study, we analyze the effect that the newly recognized cytokine interleukin (IL)-15 has on proliferation and cytokine induction using peripheral blood mononuclear cells (PBMCs) and purified CD4+ T cells from patients infected with human immunodeficiency virus (HIV) who are at various stages in their disease. We ...
IL-2 and TGF-β1 play key roles in the immunobiology of Foxp3-expressing CD25(+)CD4(+) T cells (Foxp3(+)Treg). Administration of these cytokines offers an appealing approach to manipulate the Foxp3(+)Treg pool and treat T cell-mediated autoimmunity such as type 1 diabetes. However, efficacy of cytokine treatment is dependent on the mode of application, and the potent pleiotropic effects of cytok...
A pore-forming protein (PFP; perforin) and various serine esterases (SE) have been identified in the cytoplasmic granules of CTL and NK cells. Perforin and several SE have recently been cloned. Northern blotting analysis was performed here using cDNA probes specific for human perforin and two SE (SE 1/HS and SE 2/GB) to monitor the levels of specific mRNAs in mitogen-stimulated primary human T ...
BackgroundThe prevalence of atopic dermatitis (AD) and allergic or irritant contact has been increasing significantly in the general population. Interleukin- 4 (IL-4), interleukin-6 (IL-6), immunoglobulin E (IgE) play a key role pathogenesis AD. Physalis angulata (PA) leaves reportedly have anti-inflammatory effects by impeding IL-4, IL-6, IgE. This study aimed to evaluate effect PA leaf extrac...
We analyzed interleukin (IL) 12 and IL-23 production by monocyte-derived dendritic cells (mono-DCs). Mycobacterium tuberculosis H37Rv and zymosan preferentially induced IL-23. IL-23 but not IL-12 was efficiently induced by the combination of nucleotide-binding oligodimerization domain and Toll-like receptor (TLR) 2 ligands, which mimics activation by M. tuberculosis, or by the human dectin-1 li...
