Human cytolytic T cell recognition of Yersinia pestis virulence proteins that target innate immune responses.
Cell contact by the plague bacterium Yersinia pestis initiates the injection of several virulence factors that target biochemical pathways critical for host clearance of bacteria. Despite this impairment of innate immunity, it is unclear whether antigen recognition by T cells is equally affected. We present evidence that human cytolytic T cells respond to Y. pestis virulence proteins presented ...
متن کاملHost stress and immune responses during aerosol challenge of Brown Norway rats with Yersinia pestis
Inhalation exposure models are becoming the preferred method for the comparative study of respiratory infectious diseases due to their resemblance to the natural route of infection. To enable precise delivery of pathogen to the lower respiratory tract in a manner that imposes minimal biosafety risk, nose-only exposure systems have been developed. Early inhalation exposure technology for infecti...
متن کاملRole of immune response in Yersinia pestis infection.
Yersinia pestis (Y. Pestis) is an infamous pathogen causing plague pandemics throughout history and is a selected agent of bioterrorism threatening public health. Y. pestis was first isolated by Alexandre Yersin in 1894 in Hong Kong and in the following years from all continents. Plague is enzootic in different rodents and their fleas in Africa, North and South America, and Asia, including the ...
متن کاملTemperature-modulated immunogenicity to Yersinia pestis from Yersinia enterocolitica O3.
The ability of Yersinia enterocolitica O3, grown at 25 degrees C, to promote cross-immunity to Y. pestis was lost after repeated subcultures at 37 degrees C, which selected for bacterial populations having lower in vivo survival. Subculturing Y. enterocolitica O3 from 37 to 25 degrees C restored the cross-immunogenicity although the in vivo survival remained low.
متن کاملYersinia pestis and plague.
Yersinia pestis is the aetiological agent of plague, a disease of humans that has potentially devastating consequences. Evidence indicates that Y. pestis evolved from Yersinia pseudotuberculosis, an enteric pathogen that normally causes a relatively mild disease. Although Y. pestis is considered to be an obligate pathogen, the lifestyle of this organism is surprisingly complex. The bacteria are...
