چکیده

The capacity of intramuscular (i.m.) inoculation of mice with homologous or heterologous host rotaviruses to induce protection from challenge was evaluated. i.m. inoculation with live, wild-type rotavirus (murine strain EDIM) induced complete protection from viral shedding after challenge for at least 6 weeks after inoculation; protection was correlated with production of virus-specific immunoglobulin A (IgA) by lamina propria (LP) lymphocytes. i.m. inoculation with inactivated EDIM, cell culture-adapted EDIM, or simian strain RRV was associated with partial protection, characterized by reduced viral shedding after challenge. Partial protection after challenge was not associated with production of virus-specific IgA by LP lymphocytes. The mechanisms by which i.m. inoculation induces virus-specific humoral immune responses in the small intestinal LP were examined.

Protective immunity induced by oral immunization with a rotavirus DNA vaccine encapsulated in microparticles.

DNA vaccines are usually given by intramuscular injection or by gene gun delivery of DNA-coated particles into the epidermis. Induction of mucosal immunity by targeting DNA vaccines to mucosal surfaces may offer advantages, and an oral vaccine could be effective for controlling infections of the gut mucosa. In a murine model, we obtained protective immune responses after oral immunization with ...

Immunization of C57BL/6 Mice with GRA2 Combined with MPL Conferred Partial Immune Protection against Toxoplasma gondii

BBackground: We have previously reported that immunization with GRA 2 antigen of Toxoplasma gondii induces protective immunity in CBA /J (H2k) and BALB/c mice (H2d). We aimed to examine whether immunization of a distinct strain of rodent with recombinant dense granule antigens (GRA2) combined with monophosphorryl lipid A (MPL) adjuvant elicits protective immune response against T. gondii. Metho...

Induction of mucosal B-cell memory by intramuscular inoculation of mice with rotavirus.

We investigated the capacity of intramuscular (i.m.) immunization with heterologous-host rotavirus (simian strain RRV) to induce mucosal virus-specific memory B cells in mice. We found that prior i.m. immunization enhanced the magnitude of mucosal virus-specific immunoglobulin A (IgA) production but did not alter the site and timing of induction of virus-specific IgA responses after challenge.

Distribution of rotavirus-specific memory B cells in gut-associated lymphoid tissue after primary immunization.

We found previously that mice inoculated orally with simian rotavirus strain RRV developed virus-specific memory B cell responses 16 weeks after immunization that were greater than those found 6 weeks after immunization. Memory B cell responses were defined as the quantity of virus-specific IgA detected in small intestinal lamina propria (LP) fragment cultures of immunized mice at various inter...

Association of gamma interferon and interleukin-17 production in intestinal CD4+ T cells with protection against rotavirus shedding in mice intranasally immunized with VP6 and the adjuvant LT(R192G).

Mucosal immunization of mice with chimeric, Escherichia coli-expressed VP6, the protein that comprises the intermediate capsid layer of the rotavirus particle, together with attenuated E. coli heat-labile toxin LT(R192G) as an adjuvant, reduces fecal shedding of rotavirus antigen by >95% after murine rotavirus challenge, and the only lymphocytes required for protection are CD4+ T cells. Because...
