Protease activity in Giardia duodenalis trophozoites of axenic strains isolated from symptomatic and asymptomatic patients
(Instituto Oswaldo Cruz, Ministério da Saúde, 2003-01-01)
We have examined by gelatin-SDS-PAGE the protease activity in cell lysates of Giardia duodenalis trophozoites of two axenic strains isolated in Brazil from a symptomatic patient (BTU-11) and an asymptomatic carrier (BTU-10), ...
Differentiation of epithelial cells in the urinary tract
(Springer, 2005-05-01)
Uroplakins, cytokeratins and the apical plasma membrane were studied in the epithelia of mouse urinary tract. In the simple epithelium covering the inner medulla of the renal pelvis, no uroplakins or cytokeratin 20 were ...
Invasin of Yersinia pseudotuberculosis is not a polyclonal activator of mouse B lymphocytes
(2006-12-01)
It is known that the invasin molecule of Yersinia pseudotuberculosis stimulates human peripheral B cells in vitro. In this work we evaluated the in vivo role of invasin as polyclonal activator of B lymphocytes in the mouse ...
