Bone marrow (BM)-derived professional antigen-presenting cells (pAPCs) are required for the generation of cytotoxic T lymphocyte (CTL) responses to vaccinia virus and poliovirus. Furthermore, these BM-derived pAPCs require a functional transporter associated with antigen presentation (TAP). In this report we analyze the requirements for BM-derived pAPCs and TAP in the initiation of CTL response...
In this study, virulence factors such as serum resistance, aerobactin iron uptake systems, adhesins (type 1 fimbria, P S afimbrial adhesins), haemolysine, uropathogenic spesific protein and cytotoxic necrotizing factor in 45 Escherichia coli isolates from dogs cats with urinary tract genital system infections, were investigated by both phenotypic methods molecular methods. PCR examinations of E...
Gram-negative pathogens commonly exhibit adhesive pili on their surfaces that mediate specific attachment to the host. A major class of pili is assembled via the chaperone/usher pathway. Here, the structural basis for pilus fiber assembly and secretion performed by the outer membrane assembly platform--the usher--is revealed by the crystal structure of the translocation domain of the P pilus us...
