Intranasal immunization of mice with recombinant protein antigen of serotype c Streptococcus mutans and cholera toxin B subunit.
نویسندگان
چکیده
The cholera toxin subunit and the recombinant cell-surface antigen (molecular mass of 190,000 Da) were administered intranasally to BALB/c mice. After 30 days, the mice were immunized intranasally with the recombinant protein antigen alone. High serum IgG and salivary IgA responses to the protein antigen were induced by the intranasal immunization.

Intranasal immunization of mice with group B streptococcal protein rib and cholera toxin B subunit confers protection against lethal infection.
Intranasal immunization of mice with Rib, a cell surface protein of group B streptococcus (GBS), conjugated to or simply coadministered with the recombinant cholera toxin B subunit, induces systemic immunoglobulin G (IgG) and local IgA antibody responses and confers protection against lethal GBS infection. These findings have implications for the development of a human GBS vaccine.

Background: Cholera toxin (CT), responsible for the harmful effects of cholera infection, is made up of one A subunit (enzymatic), and five B subunits (cell binding). The release of cholera toxin is the main reason for the debilitating loss of intestinal fluid. Inhibition of the B subunit (CTB) may block CT activity. Objective: To determine the effect of anti CTB-IgY against oral challenge with...
متن کاملIntranasal immunization with the cholera toxin B subunit-pneumococcal surface antigen A fusion protein induces protection against colonization with Streptococcus pneumoniae and has negligible impact on the nasopharyngeal and oral microbiota of mice.
One of the candidate proteins for a mucosal vaccine antigen against Streptococcus pneumoniae is PsaA (pneumococcal surface antigen A). Vaccines targeting mucosal immunity may raise concerns as to possible alterations in the normal microbiota, especially in the case of PsaA, which was shown to have homologs with elevated sequence identity in other viridans group streptococci. In this work, we de...

Background: Cholera as diarrheal illness is one of the most important causes of death and people's disability in different societies. Colonization factor pili (tcpA) and cholera toxin are the most important factors in the pathogenesis of Vibrio Cholera. B subunit of cholera toxin (ctxB) and tcpA have the ability to induce immune responses. The aims of this study was production of CTXB, TCPA, CT...
