--- _id: '7097' abstract: - lang: eng text: Early endosomes, also called sorting endosomes, are known to mature into late endosomesvia the Rab5-mediated endolysosomal trafficking pathway. Thus, early endosome existence isthought to be maintained by the continual fusion of transport vesicles from the plasmamembrane and thetrans-Golgi network (TGN). Here we show instead that endocytosis isdispensable and post-Golgi vesicle transport is crucial for the formation of endosomes andthe subsequent endolysosomal traffic regulated by yeast Rab5 Vps21p. Fittingly, all threeproteins required for endosomal nucleotide exchange on Vps21p arefirst recruited to theTGN before transport to the endosome, namely the GEF Vps9p and the epsin-relatedadaptors Ent3/5p. The TGN recruitment of these components is distinctly controlled, withVps9p appearing to require the Arf1p GTPase, and the Rab11s, Ypt31p/32p. These resultsprovide a different view of endosome formation and identify the TGN as a critical location forregulating progress through the endolysosomal trafficking pathway. article_number: '419' article_processing_charge: No article_type: original author: - first_name: Makoto full_name: Nagano, Makoto last_name: Nagano - first_name: Junko Y. full_name: Toshima, Junko Y. last_name: Toshima - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 - first_name: Jiro full_name: Toshima, Jiro last_name: Toshima citation: ama: Nagano M, Toshima JY, Siekhaus DE, Toshima J.

Variation in hormone transport, which depends on a delicate interplay between PIN2 sorting to and from polar plasma membrane domains, determines root growth. By employing a constitutively degraded version of PIN2, we identify brassinolides as antagonists of PIN2 endocytosis. This response does not require de novo protein synthesis, but involves early events in canonical brassinolide signaling. Brassinolide-controlled adjustments in PIN2 sorting and intracellular distribution governs formation of a lateral PIN2 gradient in gravistimulated roots, coinciding with adjustments in auxin signaling and directional root growth. Strikingly, simulations indicate that PIN2 gradient formation is no prerequisite for root bending but rather dampens asymmetric auxin flow and signaling. Crosstalk between brassinolide signaling and endocytic PIN2 sorting, thus, appears essential for determining the rate of gravity-induced root curvature via attenuation of differential cell elongation. article_number: '5516' article_processing_charge: No article_type: original author: - first_name: Katarzyna full_name: Retzer, Katarzyna last_name: Retzer - first_name: Maria full_name: Akhmanova, Maria id: 3425EC26-F248-11E8-B48F-1D18A9856A87 last_name: Akhmanova orcid: 0000-0003-1522-3162 - first_name: Nataliia full_name: Konstantinova, Nataliia last_name: Konstantinova - first_name: Kateřina full_name: Malínská, Kateřina last_name: Malínská - first_name: Johannes full_name: Leitner, Johannes last_name: Leitner - first_name: Jan full_name: Petrášek, Jan last_name: Petrášek - first_name: Christian full_name: Luschnig, Christian last_name: Luschnig citation: ama: Retzer K, Akhmanova M, Konstantinova N, et al.

Drosophila hemocytes patrol the body cavity and act as macrophages outside the nervous system whereas glia originate from the neuroepithelium and provide the scavenger population of the nervous system. Drosophila glia are hence the functional orthologs of vertebrate microglia, even though the latter are cells of immune origin that subsequently move into the brain during development. Interestingly, the Drosophila immune cells within (glia) and outside the nervous system (hemocytes) require the same transcription factor Glide/Gcm for their development. This raises the issue of how do glia specifically differentiate in the nervous system and hemocytes in the procephalic mesoderm. The Repo homeodomain transcription factor and pan-glial direct target of Glide/Gcm is known to ensure glial terminal differentiation. Here we show that Repo also takes center stage in the process that discriminates between glia and hemocytes. First, Repo expression is repressed in the hemocyte anlagen by mesoderm-specific factors. Second, Repo ectopic activation in the procephalic mesoderm is sufficient to repress the expression of hemocyte-specific genes. Third, the lack of Repo triggers the expression of hemocyte markers in glia. Thus, a complex network of tissue-specific cues biases the potential of Glide/Gcm. These data allow us to revise the concept of fate determinants and help us understand the bases of cell specification. Both sexes were analyzed.SIGNIFICANCE STATEMENTDistinct cell types often require the same pioneer transcription factor, raising the issue of how does one factor trigger different fates. In Drosophila, glia and hemocytes provide a scavenger activity within and outside the nervous system, respectively. While they both require the Glide/Gcm transcription factor, glia originate from the ectoderm, hemocytes from the mesoderm. Here we show that tissue-specific factors inhibit the gliogenic potential of Glide/Gcm in the mesoderm by repressing the expression of the homeodomain protein Repo, a major glial-specific target of Glide/Gcm. Repo expression in turn inhibits the expression of hemocyte-specific genes in the nervous system. These cell-specific networks secure the establishment of the glial fate only in the nervous system and allow cell diversification. acknowledgement: This work was supported by INSERM, CNRS, UDS, Ligue Régionale contre le Cancer, Hôpital de Strasbourg, Association pour la Recherche sur le Cancer (ARC) and Agence Nationale de la Recherche (ANR) grants.

Here we show that T-antigen in Drosophila melanogaster macrophages is involved in their developmentally programmed tissue invasion. Higher macrophage T-antigen levels require an atypical major facilitator superfamily (MFS) member that we named Minerva which enables macrophage dissemination and invasion. We characterize for the first time the T and Tn glycoform O-glycoproteome of the Drosophila melanogaster embryo, and determine that Minerva increases the presence of T-antigen on proteins in pathways previously linked to cancer, most strongly on the sulfhydryl oxidase Qsox1 which we show is required for macrophage tissue entry. Minerva’s vertebrate ortholog, MFSD1, rescues the minerva mutant’s migration and T-antigen glycosylation defects. We thus identify a key conserved regulator that orchestrates O-glycosylation on a protein subset to activate a program governing migration steps important for both development and cancer metastasis. acknowledged_ssus: - _id: LifeSc article_number: e41801 article_processing_charge: No author: - first_name: Katarina full_name: Valosková, Katarina id: 46F146FC-F248-11E8-B48F-1D18A9856A87 last_name: Valosková - first_name: Julia full_name: Biebl, Julia id: 3CCBB46E-F248-11E8-B48F-1D18A9856A87 last_name: Biebl - first_name: Marko full_name: Roblek, Marko id: 3047D808-F248-11E8-B48F-1D18A9856A87 last_name: Roblek orcid: 0000-0001-9588-1389 - first_name: Shamsi full_name: Emtenani, Shamsi id: 49D32318-F248-11E8-B48F-1D18A9856A87 last_name: Emtenani orcid: 0000-0001-6981-6938 - first_name: Attila full_name: György, Attila id: 3BCEDBE0-F248-11E8-B48F-1D18A9856A87 last_name: György orcid: 0000-0002-1819-198X - first_name: Michaela full_name: Misova, Michaela id: 495A3C32-F248-11E8-B48F-1D18A9856A87 last_name: Misova orcid: 0000-0003-2427-6856 - first_name: Aparna full_name: Ratheesh, Aparna id: 2F064CFE-F248-11E8-B48F-1D18A9856A87 last_name: Ratheesh orcid: 0000-0001-7190-0776 - first_name: Patricia full_name: Rodrigues, Patricia id: 2CE4065A-F248-11E8-B48F-1D18A9856A87 last_name: Rodrigues - first_name: Katerina full_name: Shkarina, Katerina last_name: Shkarina - first_name: Ida Signe Bohse full_name: Larsen, Ida Signe Bohse last_name: Larsen - first_name: Sergey Y full_name: Vakhrushev, Sergey Y last_name: Vakhrushev - first_name: Henrik full_name: Clausen, Henrik last_name: Clausen - first_name: Daria E full_name: Siekhaus, Daria E id: 3D224B9E-F248-11E8-B48F-1D18A9856A87 last_name: Siekhaus orcid: 0000-0001-8323-8353 citation: ama: Valosková K, Bicher J, Roblek M, et al.

Drosophila macrophage migration into the extended germband is an interesting system to study invasive migration. It carries similarities to immune cell transmigration and cancer cell invasion, therefore studying this process could also bring new understanding of invasion in higher organisms. In our work, we uncover a highly conserved member of the major facilitator family that plays a role in tissue invasion through regulation of glycosylation on a subgroup of proteins and/or by aiding the precise timing of DN-Cadherin downregulation. \r\n\r\nAberrant display of the truncated core1 O-glycan T-antigen is a common feature of human cancer cells that correlates with metastasis. Here we show that T-antigen in Drosophila melanogaster macrophages is involved in their developmentally programmed tissue invasion. Higher macrophage T-antigen levels require an atypical major facilitator superfamily (MFS) member that we named Minerva which enables macrophage dissemination and invasion. We characterize for the first time the T and Tn glycoform O-glycoproteome of the Drosophila melanogaster embryo, and determine that Minerva increases the presence of T-antigen on proteins in pathways previously linked to cancer, most strongly on the sulfhydryl oxidase Qsox1 which we show is required for macrophage tissue entry. Minerva’s vertebrate ortholog, MFSD1, rescues the minerva mutant’s migration and T-antigen glycosylation defects. We thus identify \r\na key conserved regulator that orchestrates O-glycosylation on a protein subset to activate \r\na program governing migration steps important for both development and cancer metastasis. \r\n" acknowledged_ssus: - _id: Bio alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Katarina full_name: Valosková, Katarina id: 46F146FC-F248-11E8-B48F-1D18A9856A87 last_name: Valosková citation: ama: Valosková K.
