13. Papel das citocinas IL-5 e IL-17A na diferenciação de células produtoras de anticorpos de vida longa (ASC) induzida pelo veneno do peixe Thalassophryne nattereri / The role of IL-5 and IL-17A in the differentiation of long-lived antibody secreting cells (ASC) induced by Thalassophryne nattereri fish venom
O veneno do T.nattereri induz uma resposta de memória com a diferenciação de células B B220neg, indicativo de células produtoras de anticorpos de vida longa (ASC). Para avaliar o efeito do veneno na diferenciação de ASCs, camundongos BALB/c foram imunizados e sacrificados nos dias 21, 28, 48, 74 e 120 para avaliação de anticorpos plasmáticos e cél

14. Immunology Interaction fetal-maternal in asthma: immunological reactive patterns in blood and colostrum from healthy and asthmatic mothers and in blood from their respective newborns. / Imunologia das interações materno-fetais na asma: padrões de reatividade imunológica no colostro e no sangue de mães asmáticas e no sangue de cordão de seus respectivos recém-nascidos.
Asthma has been presenting higher prevalence rates worldwide. The objective of this work is to evaluate the presence of cellular elements and humoral indicative in blood and colostrums of healthy and asthmatic mothers and in cord umbilical blood of their newborn (NB). Lower production of IgG from asthmatic mothers was observed. Dendritic cells of asthmatic m

15. Investigation of a framework based on artificial immune system applied to the pattern recognition / InvestigaÃÃo de uma arquitetura baseada em sistemas imunolÃgicos artificiais aplicada ao reconhecimento de dÃgitos manuscritos
The discovery of new functionalities through the study of human physiology has contributed toward the evolution of Artificial Immune Systems. The present work investigates a new architecture through observations of natural immunological behavior. New functionalities observed in the biological environment were studied for the modeling of this immunological ap

16. Cattle submited with vaccine stress with synthetic immunogenis challenged with Rhipicephalus (Boophilus) microplus and Babesia bovis: immunoistochemistry expression of heat shock proteins and blood biochemical / Bovinos submetidos a estresse vacinal com imunógenos sintéticos e desafiados com Rhipicephalus (Boophilus) microplus e Babesia bovis: expressão imunoistoquímica de proteínas de choque térmico (HSP70 e HSP90) e bioquímica sangüínea
The expression of HSP70 and HSP90 was evaluated through immunoistochemistry studies in bovine inoculated with synthetic peptides SBbo23290 and SBm7462 applied simultaneously, in association or in individual presentation. The animals received three applications with 30 days of interval among them and after challenged with the Babesia bovis strain UFV1 - 9th p

17. Turning immunological memory into amnesia by depletion of dividing T cells
Immunological memory, defined as more efficient immune responses on antigen reexposure, can last for decades. The current paradigm is that memory is maintained by antigen-experienced “memory T cells” that can be long-lived quiescent or dividing. The contribution of T cell division to memory maintenance is poorly known and has important clinical implicati

18. Nature of "memory" in T-cell mediated antibacterial immunity: cellular parameters that distinguish between the active immune response and a state of "memory".
Immunizing infection in mice with Listeria monocytogenes resulted in the generation of two distinct states of immunological reactivity. There was generated (i) a short-lived state of active immunity that functioned to urgently eliminate the infection organism from the tissues and (ii) a long-lives state of increased immunological potential that enabled the h

19. Cyclic development of immunological memory to bacterial lipopolysaccharide.
Immunological memory to the lipopolysaccharide of Escherichia coli O113 was generated in strains of inbred mice given a single subimmunogenic dose of either E. coli O113 lipopolysaccharide or the native protoplasmic polysaccharide of E. coli O113. Such memory, which only involved antibody of the immunoglobulin M class, developed in a cyclic manner that was c

20. Adoptive transfer of gut mucosal antitoxin memory by isolated B cells 1 year after oral immunization with cholera toxin.
A protocol was elaborated for the adoptive transfer of lymphocytes from mice which were orally immunized with cholera toxin (CT) to enable the study of long-term gut mucosal immunological memory at the single-cell level. Mesenteric lymph node (MLN) cells were transferred 1 year after priming immunizations, and recipient animals were challenged perorally on d

21. CD4+ T-Cell Subsets That Mediate Immunological Memory to Mycobacterium tuberculosis Infection in Mice
We have studied CD4+ T cells that mediate immunological memory to an intravenous infection with Mycobacterium tuberculosis. The studies were conducted with a mouse model of memory immunity in which mice are rendered immune by a primary infection followed by antibiotic treatment and rest. Shortly after reinfection, tuberculosis-specific memory cells were recr

22. Contribution of Immunological Memory to Protective Immunity Conferred by a Bacillus anthracis Protective Antigen-Based Vaccine
Protective antigen (PA)-based vaccination is an effective countermeasure to anthrax infection. While neutralizing anti-PA antibody titers elicited by this vaccine serve as good correlates for protection against anthrax (S. Reuveny, M. D. White, Y. Y. Adar, Y. Kafri, Z. Altboum, Y. Gozes, D. Kobiler, A. Shafferman, and B. Velan, Infect. Immun. 69:2888-2893, 2

24. A simple model for the immune network.
In this note I present a simple model for the idiotypic network among antibodies and study its relevance for the maintenance of immunological memory; in particular, the memory capacity of such a model is studied. Some of the similarities with the spin glass model and with neural networks are discussed.
