Papel das Yops secretadas por Yersinia sobre a resposta imune do hospedeiro

The genus Yersinia contains three species pathogenic to humans: Y. pestis, Y. enterocolitica e Y. pseudotuberculosis. The pathogenicity of Yersinia is linked to the presence of a 70-kb virulence plasmid (pYV) that is common to the three species and codifies a type III secretion system and a set of v...

Descripción
Sumario:The genus Yersinia contains three species pathogenic to humans: Y. pestis, Y. enterocolitica e Y. pseudotuberculosis. The pathogenicity of Yersinia is linked to the presence of a 70-kb virulence plasmid (pYV) that is common to the three species and codifies a type III secretion system and a set of virulence proteins, including those known as Yersinia outer proteins (Yops), that are exported by this system when the bacteria encounter host cells. Two Yops translocators (YopB and YopD) are inserted into the host plasma membrane and transport six effectors (YopO, YopH, YopM, YopJ and YopT) across the membrane into the cytosol of the host cell. The Yops effectors interfere with multiple signaling pathways of the infected cell, affecting both the innate and adaptive immune responses. This article focuses on the role of Yops in the modulation of the host immune response.
