Project description:We compared the proteomic profile of blood plasma in healthy and white-nose syndrome affected Myotis lucifugus in order to identify patho-physiological changes associated with the disease. Using two-dimensional gel electrophoresis and liquid chromatography-mass spectrometry we identified differentially expressed proteins for acute phase response, constitutive and adaptive immunity, oxidative stress defense, metabolism and structural proteins of exosomes and desmosomes, suggesting a systemic response against Pseudogymnoascus destructans infection in a North American bat species.
Project description:This dataset is provided in support of the identification of a collagen-degrading enzyme secreted by the fungus P. destructans. P. destructans is responsible for the disease white nose syndrome, which has infected and killed millions of North American bats. Our manuscript, titled "Destructin-1 is a Collagen-Degrading Endopeptidase Secreted by P. destructans, the Causative Agent of White-Nose Syndrome", is under review, and the data set will be released upon acceptance.

Project description:Bats are natural hosts for a wide diversity of viruses. While many of these viruses are highly pathogenic in humans, most do not appear to cause major symptoms in bats. These modern bat-specific characteristics are the result of past virus-host (co)evolution and virus-driven host adaptations. Innate immunity is the first line of defense against viruses in mammals, we aim at characterizing bat innate immunity in response to viruses. Using genome-wide and gene candidate evolutionary analyses, we found that many bat antiviral genes have undergone multiple duplication events in a lineage-specific manner, specifically in the Myotis bat lineage. We focus on Myotis yumanensis as a model in the Myotis lineage. We performed transcriptomic analyses and observed the upregulation of most mammalian genes implicated in the different steps of the innate immune response from sensing to interferon-stimulated genes (ISGs), showing the conservation of the core innate immunity. Our study will contribute to identifying adaptations that shaped bat innate immunity. These adaptations may contribute to the bat-virus specificity and influence viral emergence to another mammalian host
