Survival of secondary lethal systemic Francisella LVS challenge depends largely on interferon gammaKaren L Elkins
Laboratory of Mycobacterial Diseases and Cellular Immunology, Division of Bacterial, Parasitic, and Allergenic Products, CBER FDA, HFM 431, Rockville, MD 20852, USA
Microbes Infect 12:28-36. 2010..Thus successful priming of protective LVS-immune T cells, as well as complete expression of protection against Francisella during secondary challenge, depends heavily on IFN-gamma...

Laboratory of Mycobacterial Diseases and Cellular Immunology, Division of Bacterial, Parasitic, and Allergenic Products, Center for Biologics Evaluation and Research Food and Drug Administration, Rockville, MD 20852, USA
J Immunol 171:4689-99. 2003..These findings demonstrate that CD4(+) T cells possess IFN-gamma-independent mechanisms that can limit the growth of an intracellular pathogen and are dominant in secondary responses to M. tuberculosis...

Laboratory of Mycobacterial Diseases and Cellular Immunology, Division of Bacterial, Parasitic, and Allergenic Products, CBER U S FDA, Bethesda, Maryland, USA
Ann N Y Acad Sci 1105:284-324. 2007..Thus a number of known proinflammatory and Th-1 T cell related components of the immune system combat this virulent bacterium; no doubt others remain to be discovered...
Innate and adaptive immune responses to an intracellular bacterium, Francisella tularensis live vaccine strainKaren L Elkins

Microbes Infect 5:135-42. 2003..Here we review this infection model, which provides a convenient means of studying protective immune mechanisms not only for Francisella, but also for the large and important class of intracellular pathogens...
In vivo clearance of an intracellular bacterium, Francisella tularensis LVS, is dependent on the p40 subunit of interleukin-12 (IL-12) but not on IL-12 p70Karen L Elkins
Laboratory of Mycobacteria, Division of Bacterial, Parasitic, and Allergenic Products, CBER FDA, Rockville, Maryland 20852, USA
Infect Immun 70:1936-48. 2002..Instead, an additional mechanism dependent on the IL-12 p40 protein, either alone or in another complex such as the newly discovered heterodimer IL-23, appears to be responsible for actual clearance of this intracellular bacterium...
