1. Imunidade tributária recíproca e os impostos indiretos: uma interpretação conforme o Estado federal
O objetivo da presente tese é demonstrar a necessidade da não incidência dos tributos indiretos, nos casos de aquisições de bens e mercadorias por entidades políticas. A desoneração encontra justificativa constitucional, à luz da imunidade recíproca, não obstante o tema basear-se em veredicto contrário e consolidado, há décadas, no Supremo Trib

2. Is there a role for autoimmunity in immune protection against malaria?
Much remains to be known about the mechanisms involved in protective immunity against malaria and the way it is acquired. This is probably the reason why, in spite of so much progress, it has not yet been possible to develop an anti-malaria vaccine able to induce parasite specific antibodies (Ab) and/or T-cells. It has been considered in the early 80s that t

3. Role of Systemic and Mucosal Immune Responses in Reciprocal Protection against Bordetella pertussis and Bordetella parapertussis in a Murine Model of Respiratory Infection
The roles of systemic humoral immunity, cell-mediated immunity, and mucosal immunity in reciprocal protective immunity against Bordetella pertussis and Bordetella parapertussis were examined by using a murine model of respiratory infection. Passive immunization with serum from mice infected with B. pertussis established protective immunity against B. pertuss

4. Cross-Protective Antigens of Group A Streptococci Types 3 and 31 and Types 46 and 51
Reciprocal cross-protective antigens have been demonstrated between types 3 and 31 cocci, and one-way cross-protective antigens have been demonstrated between types 46 and 51 cocci. The reciprocal cross-protective antigen of types 3 and 31 is distinct from the specific M protein of either type. In the one-way cross relationship, type 46 cocci contain both ty

5. Reciprocal Protective Immunity against Bordetella pertussis and Bordetella parapertussis in a Murine Model of Respiratory Infection
The protective immunity induced by infection with Bordetella pertussis and with Bordetella parapertussis was examined in a murine model of respiratory infection. Convalescent mice that had been infected by aerosol with B. pertussis or with B. parapertussis exhibited a protective immune response against B. pertussis and also against B. parapertussis. Anti-fil

6. Cell-mediated immunity to myoglobin in polymyositis.
Using the leucocyte migration inhibition (LIF) test we looked for evidence of cell-mediated hypersensitivity against myoglobin in 8 patients with polymyositis (PM) or dermatomyositis (DM). The migration index for PM-DM patients was 47.5 +/- 17%, while in the controls the index was 86 +/- 12% (p less than 0.001). The presence of serum antibodies against myogl

7. Type 1 Immunity Provides Optimal Protection against Both Mucosal and Systemic Trypanosoma cruzi Challenges
Chagas' disease results from infection with Trypanosoma cruzi, a protozoan parasite that establishes systemic intracellular infection after mucosal invasion. We hypothesized that ideal vaccines for mucosally invasive, intracellular pathogens like T. cruzi should induce mucosal type 2 immunity for optimal induction of protective secretory immunoglobulin A (Ig

8. Orally administered microencapsulated reovirus can bypass suckled, neutralizing maternal antibody that inhibits active immunization of neonates.
Purified reovirus serotype 1, encapsulated in biodegradable aqueous microcapsules, was found to bypass maternal antibody passively transferred by suckling to neonates. Genetically identical, immunocompetent F1 scid/+ mice were generated by the reciprocal crosses of C.B17 scid/scid and normal congenic +/+ adult mice. The immunocompetent +/+ dams were either o

9. Cross-neutralization of staphylococcal and streptococcal pyrogenic toxins by monoclonal and polyclonal antibodies.
We evaluated cross-reactivity of antibodies against staphylococcal and streptococcal pyrogenic toxins. Monoclonal antibodies against staphylococcal enterotoxin (ET) C1 and streptococcal pyrogenic exotoxin (SPE) A were tested for reactivity with homologous and heterologous pyrogenic toxins in vitro. Ten immunoglobulin G1 anti-ET C1 monoclonal antibodies showe

10. A live avirulent mutant Legionella pneumophila vaccine induces protective immunity against lethal aerosol challenge.
We have examined the capacity of a live avirulent mutant form of the intracellular bacterial pathogen Legionella pneumophila to induce immune responses and protective immunity in guinea pigs. The mutant L. pneumophila is nonlethal to guinea pigs and does not revert to virulence with passage through guinea pigs. In contrast, exposure of guinea pigs to aerosol

11. 9-(1-3-Dihydroxy-2-propoxymethyl)guanine prevents death but not immunity in murine cytomegalovirus-infected normal and immunosuppressed BALB/c mice.
Immunosuppressed (from treatment with cortisone acetate and anti-thymocyte globulin) and control adult female BALB/c mice, latently infected with murine cytomegalovirus (MCMV) or lethally challenged (10(6) PFU) with MCMV intraperitoneally, were treated with 9-(1-3-dihydroxy-2-propoxymethyl)guanine (DHPG) intraperitoneally. A dose of 3 mg/kg reduced mortality

12. Fine cleavage map of a small colicin E1 plasmid carrying genes responsible for replication and colicin E1 immunity.
A small plasmid (pAO2, 1 megadalton) carrying genes responsible for replication and colicin E1 immunity has been constructed from colicin E1 plasmid (A. Oka, K. Sugimoto, and M. Takanami, Proc. Mol. Biol. Jpn., p. 113-115, 1976). pAO2 DNA was cleaved into unique fragments with seven restriction endonucleases (R.HaeII,R.HaeIII,R.HapII,R.HhaI,R.AluI,R.HgaI, an
