Immune response genes modulate serologic responses to Vibrio cholerae TcpA pilin peptides.
Cholera is an enteric disease caused by Vibrio cholerae. Toxin-coregulated pilus (TCP), a type 4 pilus expressed by V. cholerae, is a cholera virulence factor that is required for host colonization. The TCP polymer is composed of subunits of TcpA pilin. Antibodies directed against TcpA are protective in animal models of cholera. While natural or recombinant forms of TcpA are difficult to purify...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولSingle amino acid substitutions in the N-terminus of Vibrio cholerae TcpA affect colonization, autoagglutination, and serum resistance.
The toxin-coregulated pilus (TCP) of Vibrio cholerae O1 is required for successful infection of the host. TcpA, the structural subunit of TCP, belongs to the type IV family of pilins, which includes the PilE pilin of Neisseria gonorrhoeae. Recently, single amino acid changes in the N-terminus of PilE were found to abolish autoagglutination in gonococci. As type IV pilins demonstrate some simila...

Structural features, properties and regulation of the outer-membrane protein W (OmpW) of Vibrio cholerae.
The outer-membrane protein OmpW of Vibrio cholerae was studied with respect to its structure, functional properties and regulation of expression. On SDS-PAGE, the membrane-associated form of OmpW protein (solubilized by either 0.1 % or 2 % SDS at 25 degrees C) migrated as a monomer of 19 kDa that changed to 21 kDa on boiling. The protein was hyperexpressed in Escherichia coli in the histidine-t...
