Characterization of tumor necrosis factor-deficient mice.
Although tumor necrosis factor (TNF) initially came to prominence because of its anti-tumor activity, most attention is now focused on its proinflammatory actions. TNF appears to play a critical role in both early and late events involved in inflammation, from localizing the noxious agent and amplifying the cellular and mediator responses at the local site and systemically, to editing (e.g., ap...
متن کاملRole of tumor necrosis factor alpha in Helicobacter pylori gastritis in tumor necrosis factor receptor 1-deficient mice.
Increased gastric production of interleukin 8 and tumor necrosis factor alpha (TNF-alpha) has been implicated in the pathogenesis of Helicobacter pylori-associated gastroduodenal disease. In the present study we used a mouse model to demonstrate whether loss of the tumor necrosis factor receptor 1 (TNF-R1) function leads to differences in gastric inflammation or the systemic immune response in ...
متن کاملTumor necrosis factor alpha-deficient, but not interleukin-6-deficient, mice resist peripheral infection with scrapie.
In most peripheral infections of rodents and sheep with scrapie, infectivity is found first in lymphoid tissues and later in the central nervous system (CNS). Cells within the germinal centers (GCs) of the spleen and lymph nodes are important sites of extraneural replication, from which infection is likely to spread to the CNS along peripheral nerves. Here, using immunodeficient mice, we invest...
متن کاملEvaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...
متن کاملDifferential acute and chronic responses of tumor necrosis factor-deficient mice to experimental brain injury.
The present study evaluated behavioral and histopathological outcome after controlled cortical impact (CCI) brain injury in mice deficient in tumor necrosis factor [TNF(-/-)] and their wild-type (wt) littermates. Mice were subjected to CCI brain injury [TNF(-/-), n = 10; wt, n = 10] or served as uninjured controls [TNF(-/-), n = 10; wt, n = 10] and were evaluated for deficits in memory retentio...
