Global lysine crotonylation and 2-hydroxyisobutyrylation in phenotypically different Toxoplasma gondii parasites

ABSTRACT: Toxoplasma gondii is a unicellular protozoan parasite of the phylum Apicomplexa. The parasite repeatedly goes through a cycle of invasion, division and induction of host cell rupture, which is an obligatory process for proliferation inside warm-blooded animals. It is known that the biology of the parasite is controlled by a variety of mechanisms ranging from genomic to epigenetic to transcriptional regulation. In this study, we investigated the global protein posttranslational lysine crotonylation and 2-hydroxyisobutyrylation of two T. gondii strains, RH and ME49, which represent distinct phenotypes for proliferation and pathogenicity in the host. Proteins with differential expression and modification patterns associated with parasite phenotypes were identified. Many proteins in T. gondii were crotonylated and 2-hydroxyisobutyrylated, and they were localized in diverse subcellular compartments involved in a wide variety of cellular functions such as motility, host invasion, metabolism and epigenetic gene regulation. These findings suggest that lysine crotonylation and 2-hydroxyisobutyrylation are ubiquitous throughout the T. gondii proteome, regulating critical functions of the modified proteins. These data provide a basis for identifying important proteins associated with parasite development and pathogenicity.

Project description:Microglia are innate immune cells of the brain that perform phagocytic and inflammatory functions in disease conditions. Transcriptomic studies of acutely-isolated microglia have provided novel insights into their molecular and functional diversity in homeostatic and neurodegenerative disease states. State-of-the-art mass spectrometric methods can comprehensively characterize proteomic alterations in microglia in neurodegenerative disorders, potentially providing novel functionally-relevant molecular insights that are not provided by transcriptomics. However, proteomic profiling of adult primary microglia in neurodegenerative disease conditions has not been performed. We performed quantitative proteomic analyses of purified CD11b+ acutely-isolated microglia adult mice in normal, acute neuroinflammatory (LPS-treatment) and chronic neurodegenerative states (5xFAD model of Alzheimer’s disease [AD]) using tandem mass tag mass spectrometry. Differential expression analyses were performed to characterize specific microglial proteomic changes in 5xFAD mice and identify overlap with LPS-induced pro-inflammatory changes. Our results were also contrasted with existing proteomic data from wild-type mouse microglia and from existing microglial transcriptomic data from wild-type and 5xFAD mice. Neuropathological validation studies of select proteins were performed in human AD and 5xFAD brains. Of 4,133 proteins identified, 187 microglial proteins were differentially expressed in the 5xFAD mouse model of AD pathology, including proteins with previously known (Apoe, Clu and Htra1) as well as previously unreported relevance to AD biology (Cotl1 and Hexb). Proteins upregulated in 5xFAD microglia shared significant overlap with pro-inflammatory changes observed in LPS-treated mice. Several proteins increased in human AD brain were also upregulated by 5xFAD microglia (Aβ peptide, Apoe, Htra1, Cotl1 and Clu). Cotl1 was identified as a novel microglia-specific marker with increased expression and strong association with AD neuropathology. Apoe protein was also detected within plaque-associated microglia in which Apoe and Aβ were highly co-localized suggesting a role for Apoe in phagocytic clearance of Aβ. We report the first comprehensive comparative proteomic study of adult mouse microglia derived from acute neuroinflammatory and AD models, representing a valuable resource to the neuroscience research community. We highlight shared and unique microglial proteomic changes in acute neuroinflammatory, aging and AD mouse models in addition to identifying novel roles for microglial proteins in human neurodegeneration.

Project description:Toxoplasma gondii is an obligate intracellular parasite which can cause toxoplasmosis. Surface and secreted proteins of T. gondii play important roles in infection and immunity, and also are antigen targets in immunological diagnosis and vaccine development. However, it is difficult to investigate identities and antigenicities of surface and secreted proteins due to limitation of surface protein extraction methods. In this study, a total of 785 potential surface and secreted proteins of T. gondii RH tachyzoites were identified using a method combination of biotin labeling, avidin chromatography isolation, and high flux proteomics (LC-MS/MS). Among the highly-expressed 65 proteins, 43 proteins (66%) were originally annotated as surface or secreted proteins in the released T. gondii genomes, which proved the method combination to be a credible strategy. Furthermore, the transcriptomic responses and cytokine secretions induced by the isolated proteins, the live T. gondii RH tachyzoites infection, and the live pathogenic E. coli infection, in the human peripheral blood monocyte THP-1 cell lines, were comparatively analyzed to reveal antigenicities and immunobiological properties of T. gondii surface and secreted proteins. The transciptomic profiles induced by the isolated proteins were similar to those induced by the live bacterium infection, but were different from those induced by the live parasite infection. Contrary to the low cytokine secretion induced by the live parasite infection, the isolated proteins induced significant cytokine and chemokines secretion. Especially, the secretions of several chemokines induced by the isolated proteins were even higher than those induced by the live bacterium infection. These data suggested that T. gondii surface and secreted proteins were effective antigens, while the live parasite could evade the host innate immunity. This study comprehensively revealed the identities and antigenicities of T. gondii surface and secreted proteins, which laid foundation for further screening new T. gondii antigens, developing immunological diagnosis methods, and studying host immune response to T. gondii infection.
