Tumor necrosis factor (TNF-alpha) significantly reduced Cryptosporidium parvum development in a murine enterocyte cell line, and a key mechanism of action appeared to be inhibition of parasite invasion. However, TNF-alpha-deficient mice controlled infection as effectively as wild-type mice. This suggests that TNF-alpha might have only a redundant role for establishing immunity against C. parvum.

  Background: Several components of metabolic syndrome (MetS) facilitate its diagnosis, including abdominal obesity, hyperlipidemia, high blood pressure, and insulin resistance. The production of tumor necrosis factor-alpha (TNF-alpha) and interleukin 6 (IL-6) seem to be associated with MetS components. The aim of this study was to evaluate the correlation between  the serum levels...

Stereoscopic observation via an implanted sight glass in mice bearing transplanted methylcholanthrene-induced A-cells showed tumorivascular hemorrhage at 1-2 h after tumor necrosis factor (TNF) administration, congestion at 4-6 h, and hemorrhage, congestion, and blood circulation blockage at 24 h. Histological examination after TNF administration to mice bearing similar methylcholanthrene-induc...

In this study we cloned and analysed partial cDNA of tumor necrosis factor (TNF) and p75 TNF-R receptor of Syrian golden hamster (Mesocricetus auratus). We obtained a 382-bp sequence of TNF and a 148-bp sequence coding for p75 TNF-R. The primers used for the cloning were designed on the basis of inter-species homology, thus presumably can be used for cloning and analysis of TNF and p75 TNF-R ge...

Human bone marrow mesenchymal stem cells (MSCs) are a potent source of growth factors, which are partly responsible for their beneficial paracrine effects. We reported previously that transforming growth factor-alpha (TGF-alpha), a putative mediator of wound healing and the injury response, increases the release of vascular endothelial growth factor (VEGF), augments tumor necrosis factor-alpha ...

introduction:to evaluate the role of allergic-type and infectious-type cytokines in children with chronic otitis media with effusion (ome) materials and methods:we investigated serum levels of interleukins (il)-4, il-5, and il-13, along with interferon-gamma (ifn-γ) and tumor necrosis factor-alpha (tnf-α), by enzyme-linked immunosorbent assay (elisa) in 35 children with ome and 28 healthy contr...

Objective: To observe the effect of Fastigial Nucleus Stimulation (FNS) on serum inflammatory factors in patients with coronary heart disease. Methods: 144 disease were randomly divided into experimental group (n = 72) and control 72). The received conventional medication for was given cerebellar nucleus electrical stimulation basis routine medication. High-sensitivity C-reactive protein (hs-CR...

PURPOSE. In many cell types, tumor necrosis factor (TNF)– induced apoptosis is prevented by production of TNF– induced antiapoptotic protein, a process mediated by nuclear transcription factor (NF)B. TNFis widely expressed in proliferative vitreoretinopathy (PVR) membranes and is present in the vitreous of eyes with PVR. To understand mechanisms responsible for RPE cell survival and death in th...

Tumor necrosis factor (TNF) is a cytokine produced by monocytes and other cells with selective cytolytic activity against some but not all tumor cells. Cellular resistance to the cytolytic effects of TNF has been reported to be associated with autocrine production of TNF by the target cells. The purpose of this study was to determine whether or not human tumors produce tumor necrosis factor in ...
