Yersinia Pestis Virulence Factor Yopm Undermines The Function Of Distinct Ccr2+Gr1+ Cells In Spleen And Liver During Systemic Plague, Zhan Ye
University of Kentucky Doctoral Dissertations
Yersinia pestis, the infective agent of bubonic and pneumonic plague, is classified as a category A agent of bioterrorism. YopM, a protein toxin of Y. pestis, is necessary for full virulence in a systemic plague mouse model with ambient-temperature grown bacteria. We used this model to identify the cells undermined by YopM. Natural killer (NK) cells were previously reported to be lost in spleen and blood in a YopM-associated way; however, NK cell depletion was found not to occur in liver, and ablation of NK cells had no effect on bacterial growth, indicating that NK cells are redundant …
