A inflamação é uma resposta vascular, celular e humoral, responsável pelo processo de defesa dos organismos vivos ante agentes agressores. Essa resposta fisiológica é resultante da ação coordenada entre o sistema imunológico e o tecido no qual ocorreu a lesão. Por incorporar vários mecanismos biológicos, como a formação de edema, fagocitose, angiogênese, fibroplasia, liberação de mediadores químicos, além de ou...
Intestinal mucositis is a common side effect of irinotecan-based anticancer regimens. Mucositis causes cell damage, bacterial/endotoxin translocation and production of cytokines including IL–1 and IL–18. These molecules and toll-like receptors (TLRs) activate a common signaling pathway that involves the Myeloid Differentiation adaptor protein, MyD88, whose role in intestinal mucositis is unknown. Then, we evalu...
Hemorrhagic cystitis (HC) induced by ifosfamide (IFO) is an important clinical complication in patients with cancer. Despite prophylaxis, HC is observed. The role of interleukin-1 (IL-1) and tumor necrosis factor (TNF) in the pathogenesis of HC provides targets for treatment. Thus, this study aimed to evaluate the protective effect of the IL-1 receptor antagonist (anakinra) and anti-TNF-alpha antibody (inflixim...
