IL-10 inhibits the NF-κB and ERK/MAPK-mediated production of pro-inflammatory mediators by up-regulation of SOCS-3 in Trypanosoma cruzi-infected cardiomyocytes.

Trypanosoma cruzi (T. cruzi) infection produces an intense inflammatory response which is critical for the control of the evolution of Chagas' disease. Interleukin (IL)-10 is one of the most important anti-inflammatory cytokines identified as modulator of the inflammatory reaction.

Macrophages derived from septic mice modulate nitric oxide synthase and angiogenic mediators in the heart.

Macrophages (Mps) can exert the defense against invading pathogens. During sepsis, bacterial lipopolisaccharide (LPS) activates the production of inflammatory mediators by Mps. Nitric oxide synthase (NOS) derived-nitric oxide (NO) is one of them.

PPARγ ligand treatment inhibits cardiac inflammatory mediators induced by infection with different lethality strains of Trypanosoma cruzi.

Trypanosoma cruzi (T. cruzi), the etiological agent of Chagas' disease, causes cardiac alterations in the host. Although the main clinical manifestations arise during the chronic stage, the mechanisms leading to heart damage develop early during infection.

Role of PPARs in Trypanosoma cruzi Infection: Implications for Chagas Disease Therapy.

Chagas disease, which is caused by Trypanosoma cruzi (T. cruzi), remains a substantial public health concern and an important cause of morbidity and mortality in Latin America. T.

Modulation of inflammatory response and parasitism by 15-Deoxy-Δ(12,14) prostaglandin J(2) in Trypanosoma cruzi-infected cardiomyocytes.

Trypanosoma cruzi infection produces an intense inflammatory response in diverse tissues including the heart. The inflammatory reaction is critical for the control of the parasites' proliferation and evolution of Chagas disease. 15-Deoxy-Δ(12,14) prostaglandin J(2) (15dPGJ2) can repress the inflammatory response in many experimental models.

15-deoxy-Delta12,14 prostaglandin GJ2 but not rosiglitazone regulates metalloproteinase 9, NOS-2, and cyclooxygenase 2 expression and functions by peroxisome proliferator-activated receptor gamma-dependent and -independent mechanisms in cardiac cells.

Sepsis or endotoxemia produced by LPS followed by hypotension and multiorganic failure may lead to cardiac dysfunction contributing to mortality. Cardiac failure is usually associated to activation of nuclear factor kappaB (NF-kappaB) and mitogen-activated protein kinase (MAPK), which play an important role in proinflammatory enzymes expression. It has been shown that 15-deoxy-Delta12,14 prostaglandin J2 (15dPGJ2) can repress the inflammatory response by means of peroxisome proliferator-activated receptor gamma (PPARgamma)-dependent and -independent mechanisms.

Salmonella enterica serovar Enteritidis dam mutant induces low NOS-2 and COX-2 expression in macrophages via attenuation of MAPK and NF-kappaB pathways.

Although dam mutants of Salmonella have been proposed as live vaccines, their capacity to trigger cell inflammatory cascades has not been fully elucidated. We investigated in detail the ability of Salmonella enterica dam mutant to activate the signalling pathways of the inflammatory response in RAW 264.7 cells.
