“…This effect was dependent on the presence of macrophages as well as on the proteolytic activity of this SVMP. Further investigations have also shown that jararhagin can directly stimulate the expression of mRNA encoding for TNF, IL-1 and IL-6 by elicited macrophages (Clissa et al 2001). This suggests that macrophages are important targets for SVMP, although the cell binding site has not yet been characterized.…”

“…This suggests that macrophages are important targets for SVMP, although the cell binding site has not yet been characterized. Inactivation of the catalytic activity of jararhagin had no effect on jararhagininduced stimulatory effect on macrophages, pointing to a role for the disintegrin-like/cysteine domain in this effect (Clissa et al 2001). Investigations using knockout mice deficient in TNF receptors and IL-6 have demonstrated that both are relevant for development of jararhagin-induced necrosis but not edema nor hemorrhage (Laing et al 2003).…”

“…Vários estudos têm demonstrado o papel da jararagina, uma SVMP da classe PIII isolada do veneno de Bothrops jararaca, nos processos inflamatórios que ocorrem após o envenenamento (MOURA-DA-SILVA et al, 1996;CLISSA et al, 2001;LAING et al, 2003;COSTA et al, 2002;GALLAGHER et al, 2005). Em um estudo realizado pelo nosso grupo, GALLAGHER et al, 2005).…”

“…É interessante observar que, apesar de encontrarmos elevados níveis de RNA mensageiro nestas células, não houve aumento significativo nos níveis desta molécula de adesão expressas na superfície de HUVECs estimuladas com a jararagina. Em um estudo anterior Clissa et al (2001) demonstraram que a jararagina tinha uma ação de degradação total ou parcial sobre citocinas pró-inflamatórias em sobrenadante de cultura de células; por isso, nós fomos investigar se este efeito também seria o responsável pela ausência da expressão de E-selectina na superfície de…”
