Response of macrophage Toll-like receptor 4 to a Sporothrix schenckii lipid extract during experimental sporotrichosis
(Immunology, 2009-10-01) [Artigo]
P>Toll-like receptors have been implicated in the recognition of various pathogens, including bacteria, viruses, protozoa and fungi. However, no information is available about Toll-like receptor 4 (TLR4) participation in ...
Ativação de macrófagos por produtos naturais obtidos da Achillea millefolium L. (Asteraceae)
(Revista de Ciencias Farmaceuticas, 2003-12-01) [Artigo]
Plants are a valuable source of natural products for the maintenance of human health. The purpose of this paper was the study of immunologic activity of yarrow (Achillea millefolium L.), a largely used plant in popular ...
Interação das enterotoxinas estafilocócicas com o sistema imune do hospedeiro
(Revista de Ciencias Farmaceuticas, 2004-10-14) [Resenha]
Staphylococcal enterotoxins are among the most common etiologic agents that cause food poisoning and, possibly, nonmenstrual toxic shock syndrome. These enterotoxins are also called superantigens because they are potent T ...
TNF-alpha, H2O2 and NO response of peritoneal macrophages to Yersinia enterocolitica O : 3 derivatives
(Microbes and Infection, 2004-02-01) [Artigo]
In this study, the effect of Yersinia derivatives on nitric oxide (NO), hydrogen peroxide (H2O2) and tumor necrosis factor-alpha (TNF-alpha) production by murine peritoneal macrophages was investigated. Addition of ...
Influence of Yersinia pseudotuberculosis outer proteins (Yops) on interleukin-12, tumor necrosis factor alpha and nitric oxide production by peritoneal macrophages
(Immunology Letters, 2004-06-15) [Artigo]
An essential key to pathogenicity in Yersinia is the presence of a 70 kb plasmid (pYV) which encodes a type-III secretion system and several virulence outer proteins whose main function is to enable the bacteria to survive ...
Influence of Th1/Th2 cytokines and nitric oxide in murine systemic infection induced by Sporothrix schenckii
(Mycopathologia, 2006-01-01) [Artigo]
In an attempt to elucidate the effects of Sporothrix schenckii infection on the immune response, our laboratory has developed a murine model of disseminated sporotrichosis. Helper T cells can be further subdivided into Th1 ...
