Patent number: 10925945Abstract: The present invention relates to the preparation and use in primates of whole organismvaccines in which the MEP pathway is disrupted such that synthesis of HMBPP by the bacterial cells is substantially blocked. The data provided demonstrates that, when bacteria or other vaccine vectors that comprise an active MEP pathway are used in vaccine methods, the ?? T cell response dominates, potentially clearing the vaccine strain via ?? T cell-mediated killing of vector infected antigen presenting cells and reducing its utility as a stimulator of a productive adaptive immune response, specifically priming or boosting of CD4+ and CD8+ ?? T cell responses, specific for listerial-encoded antigens. By disrupting the MEP pathway, activation and expansion of ?? T cells is limited in the recipient primate, resulting in resulting in an increase in the magnitude and duration of inflammation and in the magnitude and duration of antigen presentation by the cellular vaccine.Type: GrantFiled: October 13, 2015Date of Patent: February 23, 2021Assignee: PROVIDENCE HEALTH & SERVICES-OREGONInventors: Keith Bahjat, Yoshinobu Koguchi, Alejandro F.

Publication number: 20110262480Abstract: Method for producing multiple modifications in the chromosome of Gram-negative bacteria and Salmonella strains which are deficient in c-di-GMP synthesis obtained by said method. The method can be used to make multiple modifications in the genome of Gram-negative bacteria, simply and efficiently, using the plasmids of the invention, which comprise a marker gene under the control of a constitutive promoter, a replication origin specific for Gram-negative bacteria, a gene which encodes a heat-sensitive protein essential for initiating replication of the plasmid, making the replication origin heat-sensitive, and a counter-selection gene.Type: ApplicationFiled: May 21, 2010Publication date: October 27, 2011Inventors: Cristina Solano, Begoña García, Alejandro Toledo-Arana, Cristina Latasa, Violeta Zorraquino, Jaione Valle, Iñigo Lasa

Publication number: 20110229515Abstract: A method for identifying a microorganism having a reduced adaptation to a particular environment comprising the steps of: (1) providing a plurality of microorganisms each of which is independently mutated by the insertional inactivation of a gene with a nucleic acid comprising a unique marker sequence so that each mutant contains a different marker sequence, or clones of the said microorganism; (2) providing individually a stored sample of each mutant produced by step (1) and providing individually stored nucleic acid comprising the unique marker sequence from each individual mutant; (3) introducing a plurality of mutants produced by step (1) into the said particular environment and allowing those microorganisms which are able to do so to grow in the said environment; (4) retrieving microorganisms from the said environment or a selected part thereof and isolating the nucleic acid from the retrieved microorganisms; (5) comparing any marker sequences in the nucleic acid isolated in step (4) to the unique marType: ApplicationFiled: September 27, 2010Publication date: September 22, 2011Inventor: David William HOLDEN
