Journal ArticleDOI
Cryptococcal transmigration across a model brain blood-barrier: Evidence of the Trojan horse mechanism and differences between Cryptococcus neoformans var. grubii strain H99 and Cryptococcus gattii strain R265
Tania C. Sorrell,Pierre-Georges Juillard,Julianne T. Djordjevic,Keren Kaufman-Francis,Anelia Dietmann,Alban Milonig,Valery Combes,Georges E. Grau +7 more
TL;DR: It was shown that phagocytosis of Cn by non-interferon (IFN)-γ stimulated THP-1 cells was higher than that of Cg, and more Cn-loaded macrophages were transported across an intact HBEC monolayer, consistent with the predilection of CN for CNS infection.
Journal ArticleDOI
Pho4 Is Essential for Dissemination of Cryptococcus neoformans to the Host Brain by Promoting Phosphate Uptake and Growth at Alkaline pH.
Sophie Lev,Keren Kaufman-Francis,Desmarini Desmarini,Pierre Juillard,Cecilia Li,Sebastian A. Stifter,Sebastian A. Stifter,Carl G. Feng,Carl G. Feng,Tania C. Sorrell,Georges E. Grau,Yong Sun Bahn,Julianne T. Djordjevic +12 more
TL;DR: D dissemination of infection and the pathogenesis of meningitis are dependent on cryptococcal phosphate uptake and stress tolerance at alkaline pH, both of which are Pho4 dependent.
Journal ArticleDOI
The Early Innate Immune Response to, and Phagocyte-Dependent Entry of, Cryptococcus neoformans Map to the Perivascular Space of Cortical Post-Capillary Venules in Neurocryptococcosis
Keren Kaufman-Francis,Julianne T. Djordjevic,Pierre-Georges Juillard,Sophie Lev,Desmarini Desmarini,Georges E. Grau,Tania C. Sorrell +6 more
TL;DR: It is demonstrated for the first time that the PVS of cortical post-capillary venules is the major site of the early innate immune response to, and phagocyte-dependent entry of, C. neoformans.
Journal ArticleDOI
IP7-SPX Domain Interaction Controls Fungal Virulence by Stabilizing Phosphate Signaling Machinery.
Desmarini Desmarini,Sophie Lev,David Furkert,Ben Crossett,Adolfo Saiardi,Keren Kaufman-Francis,Cecilia Li,Tania C. Sorrell,Lorna Wilkinson-White,Jacqueline M. Matthews,Dorothea Fiedler,Julianne T. Djordjevic +11 more
TL;DR: It is demonstrated that interaction of the inositol pyrophosphate, IP7, with the CDK inhibitor protein, Pho81, is instrumental in promoting fungal virulence and provides novel mechanistic insight into the role of IP7 in PHO pathway regulation by demonstrating that IP7 functions as an intermolecular “glue” to stabilize Pho 81 association with Pho85/Pho80 and, hence, promotePHO pathway activation and phosphate acquisition.
Journal ArticleDOI
The PHO signaling pathway directs lipid remodeling in Cryptococcus neoformans via DGTS synthase to recycle phosphate during phosphate deficiency.
Sophie Lev,Thusitha Rupasinghe,Desmarini Desmarini,Keren Kaufman-Francis,Tania C. Sorrell,Ute Roessner,Julianne T. Djordjevic +6 more
TL;DR: It is demonstrated that Bta1-dependent substitution of PC by betaine lipids is tightly regulated in C. neoformans by the PHO pathway, to conserve phosphate and preserve membrane integrity and function.
