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.

text: Arabidopsis PIN2 protein directs transport of the phytohormone auxin from
the root tip into the root elongation zone. 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.

text: Despite their different origins, Drosophila glia and hemocytes are related
cell populations that provide an immune function. 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.

text: Aberrant 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
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.

text: "Invasive migration plays a crucial role not only during development and homeostasis
but also in pathological states, such as tumor metastasis. 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.

text: Migrating cells penetrate tissue barriers during development, inflammatory
responses, and tumor metastasis. We study if migration in vivo in such three-dimensionally
confined environments requires changes in the mechanical properties of the surrounding
cells using embryonic Drosophila melanogaster hemocytes, also called macrophages,
as a model. We find that macrophage invasion into the germband through transient
separation of the apposing ectoderm and mesoderm requires cell deformations and
reductions in apical tension in the ectoderm. Interestingly, the genetic pathway
governing these mechanical shifts acts downstream of the only known tumor necrosis
factor superfamily member in Drosophila, Eiger, and its receptor, Grindelwald.
Eiger-Grindelwald signaling reduces levels of active Myosin in the germband ectodermal
cortex through the localization of a Crumbs complex component, Patj (Pals-1-associated
tight junction protein). We therefore elucidate a distinct molecular pathway that
controls tissue tension and demonstrate the importance of such regulation for
invasive migration in vivo.

text: Clathrin-mediated endocytosis requires the coordinated assembly of various
endocytic proteins and lipids at the plasma membrane. Accumulating evidence demonstrates
a crucial role for phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2) in endocytosis,
but specific roles for PtdIns(4)P other than as the biosynthetic precursor of
PtdIns(4,5)P2 have not been clarified. In this study we investigated the role
of PtdIns(4)P or PtdIns(4,5)P2 in receptor-mediated endocytosis through the construction
of temperature-sensitive (ts) mutants for the PI 4-kinases Stt4p and Pik1p and
the PtdIns(4) 5-kinase Mss4p. Quantitative analyses of endocytosis revealed that
both the stt4(ts)pik1(ts) and mss4(ts) mutants have a severe defect in endocytic
internalization. Live-cell imaging of endocytic protein dynamics in stt4(ts)pik1(ts)
and mss4(ts) mutants revealed that PtdIns(4)P is required for the recruitment
of the alpha-factor receptor Ste2p to clathrin-coated pits whereas PtdIns(4,5)P2
is required for membrane internalization. We also found that the localization
to endocytic sites of the ENTH/ANTH domain-bearing clathrin adaptors, Ent1p/Ent2p
and Yap1801p/Yap1802p, is significantly impaired in the stt4(ts)pik1(ts) mutant,
but not in the mss4(ts) mutant. These results suggest distinct roles in successive
steps for PtdIns(4)P and PtdIns(4,5)P2 during receptor-mediated endocytosis.

text: The phytohormone auxin is the information carrier in a plethora of developmental
and physiological processes in plants(1). It has been firmly established that
canonical, nuclear auxin signalling acts through regulation of gene transcription(2).
Here, we combined microfluidics, live imaging, genetic engineering and computational
modelling to reanalyse the classical case of root growth inhibition(3) by auxin.
We show that Arabidopsis roots react to addition and removal of auxin by extremely
rapid adaptation of growth rate. This process requires intracellular auxin perception
but not transcriptional reprogramming. The formation of the canonical TIR1/AFB-Aux/IAA
co-receptor complex is required for the growth regulation, hinting to a novel,
non-transcriptional branch of this signalling pathway. Our results challenge the
current understanding of root growth regulation by auxin and suggest another,
presumably non-transcriptional, signalling output of the canonical auxin pathway.

text: The intercellular transport of auxin is driven by PIN-formed (PIN) auxin efflux
carriers. PINs are localized at the plasma membrane (PM) and on constitutively
recycling endomembrane vesicles. Therefore, PINs can mediate auxin transport either
by direct translocation across the PM or by pumping auxin into secretory vesicles
(SVs), leading to its secretory release upon fusion with the PM. Which of these
two mechanisms dominates is a matter of debate. Here, we addressed the issue with
a mathematical modeling approach. We demonstrate that the efficiency of secretory
transport depends on SV size, half-life of PINs on the PM, pH, exocytosis frequency
and PIN density. 3D structured illumination microscopy (SIM) was used to determine
PIN density on the PM. Combining this data with published values of the other
parameters, we show that the transport activity of PINs in SVs would have to be
at least 1000× greater than on the PM in order to produce a comparable macroscopic
auxin transport. If both transport mechanisms operated simultaneously and PINs
were equally active on SVs and PM, the contribution of secretion to the total
auxin flux would be negligible. In conclusion, while secretory vesicle-mediated
transport of auxin is an intriguing and theoretically possible model, it is unlikely
to be a major mechanism of auxin transport inplanta.

text: 'Immune cells migrating to the sites of infection navigate through diverse
tissue architectures and switch their migratory mechanisms upon demand. However,
little is known about systemic regulators that could allow the acquisition of
these mechanisms. We performed a genetic screen in Drosophila melanogaster to
identify regulators of germband invasion by embryonic macrophages into the confined
space between the ectoderm and mesoderm. We have found that bZIP circadian transcription
factors (TFs) Kayak (dFos) and Vrille (dNFIL3) have opposite effects on macrophage
germband infiltration: Kayak facilitated and Vrille inhibited it. These TFs are
enriched in the macrophages during migration and genetically interact to control
it. Kayak sets a less coordinated mode of migration of the macrophage group and
increases the probability and length of Levy walks. Intriguingly, the motility
of kayak mutant macrophages was also strongly affected during initial germband
invasion but not along another less confined route. Inhibiting Rho1 signaling
within the tail ectoderm partially rescued the Kayak mutant phenotype, strongly
suggesting that migrating macrophages have to overcome a barrier imposed by the
stiffness of the ectoderm. Also, Kayak appeared to be important for the maintenance
of the round cell shape and the rear edge translocation of the macrophages invading
the germband. Complementary to this, the cortical actin cytoskeleton of Kayak-
deficient macrophages was strongly affected. RNA sequencing revealed the filamin
Cheerio and tetraspanin TM4SF to be downstream of Kayak. Chromatin immunoprecipitation
and immunostaining revealed that the formin Diaphanous is another downstream target
of Kayak. Immunostaining revealed that the formin Diaphanous is another downstream
target of Kayak. Indeed, Cheerio, TM4SF and Diaphanous are required within macrophages
for germband invasion, and expression of constitutively active Diaphanous in macrophages
was able to rescue the kayak mutant phenotype. Moreover, Cher and Diaphanous are
also reduced in the macrophages overexpressing Vrille. We hypothesize that Kayak,
through its targets, increases actin polymerization and cortical tension in macrophages
and thus allows extra force generation necessary for macrophage dissemination
and migration through confined stiff tissues, while Vrille counterbalances it.'
