Host response to S. pneumoniae TIGR4 and ΔpotABCD

Project description:The aim of this experiment is to determine the difference in protein expression, if any, in a mouse model of pneumococcal pneumonia using wild type and a polyamine transport operon deletion mutant strain of S. pneumoniae TIGR4, using expression proteomics. Eight week old female C57bl/6 mice were used in this study. The experimental design had two groups of 3 animals each that were administered 50 µL 1 X 107 CFU wild type S. pneumoniae TIGR4 or S. pneumoniae TIGR4 ΔpotABCD strain by intranasal instillation. The control group with three animals received 50 µL PBS. Mice were euthanized 4 hr and 12 hr post infection and lung tissues were harvested. The control group animals were euthanized 12 hr post infection.

Misregulation of the broad-range phospholipase C activity increases the susceptibility of Listeria monocytogenes to intracellular killing by neutrophils

Project description:Listeria monocytogenes is a facultative intracellular bacterial pathogen that tightly regulates the activities of various virulence factors during infection. A mutant strain (the plcBΔpro mutant) that has lost the ability to control the activity of a phospholipase C (PC-PLC) is attenuated a hundred fold in mice. This attenuation is not due to a lack of bacterial fitness, but appears to result from a modified host response to infection. The transcriptomic pattern of immunerelated genes in infected macrophages indicated no differential response to wild-type L. monocytogenes vs the plcBΔpro mutant.

Gene Expression Timecourse of WT, DUBmut, and EndoUmut Mouse Hepatitis Virus Strain A59 infected C57bl/6 Bone Marrow derived macrophages

Project description:We report the differences in innate immune activation in the comparison of wild type and mutant Mouse Hepatitis Virus Strain A59 infection of bone marrow derived macrophages. We infected BMDMs and harvested RNA at 3, 6, 9, and 12 hpi while comparing changes in host gene expression compared to mock infected cells. Here, using a transcriptomics approach, we compared the scope and kinetics of the host response to the wild type, DUBmut, and EndoUmut viruses in infected macrophages. We found that the EndoUmut virus activates a focused response, predominantly involving type I interferons and a subset of interferon-responsive genes, within 12 hours after infection. In contrast, the wild type and DUBmut viruses stimulate the upregulation of over 2,800 genes, including the activation of unfolded protein response (UPR) pathways and a proinflammatory response associated with viral pathogenesis. This study highlights the role of viral interferon antagonists in modulating the kinetics and magnitude of the host response during virus infection and demonstrates that inactivation of a dominant viral antagonist, the coronavirus endoribonuclease, dramatically alters the host response in macrophages and the disease process.

Genomic Analysis of Relapsed Pediatric Acute Lymphoblastic Leukemia

Project description:<p>Although multi-agent combination chemotherapy is curative in a significant fraction of childhood acute lymphoblastic leukemia (ALL) patients, 20% of cases relapse and most die due to chemo-refractory disease. Here we used whole-exome and whole-genome sequencing to analyze the mutational landscape and pattern of clonal evolution at relapse in pediatric ALL cases. These analyses showed that ALL relapses originate from a common ancestral precursor clone of the diagnosis and relapsed populations and frequently harbor mutations implicated in chemotherapy resistance. RAS-MAPK pathway activating mutations in NRAS, KRAS and PTPN11 were present in 24/55 (44%) cases in our series. Notably, while some cases showed emergence of RAS mutant clones at relapse, in others, RAS mutant clones present at diagnosis were replaced by RAS wild type populations. Mechanistically, functional dissection of mouse and human wild type Kras and mutant Kras (Kras G12D) isogenic leukemia cells demonstrated induction of methotrexate resistance, but also improved response to vincristine, in mutant Kras- expressing lymphoblasts. These results identify chemotherapy driven selection as a central mechanism of leukemia clonal evolution and pave the road for the development of tailored personalized therapies for the treatment of relapsed ALL. </p>
