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: '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.'

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: Drosophila melanogaster plasmatocytes, the phagocytic cells among hemocytes,
are essential for immune responses, but also play key roles from early development
to death through their interactions with other cell types. They regulate homeostasis
and signaling during development, stem cell proliferation, metabolism, cancer,
wound responses and aging, displaying intriguing molecular and functional conservation
with vertebrate macrophages. Given the relative ease of genetics in Drosophila
compared to vertebrates, tools permitting visualization and genetic manipulation
of plasmatocytes and surrounding tissues independently at all stages would greatly
aid in fully understanding these processes, but are lacking. Here we describe
a comprehensive set of transgenic lines that allow this. These include extremely
brightly fluorescing mCherry-based lines that allow GAL4-independent visualization
of plasmatocyte nuclei, cytoplasm or actin cytoskeleton from embryonic Stage 8
through adulthood in both live and fixed samples even as heterozygotes, greatly
facilitating screening. These lines allow live visualization and tracking of embryonic
plasmatocytes, as well as larval plasmatocytes residing at the body wall or flowing
with the surrounding hemolymph. With confocal imaging, interactions of plasmatocytes
and inner tissues can be seen in live or fixed embryos, larvae and adults. They
permit efficient GAL4-independent FACS analysis/sorting of plasmatocytes throughout
life. To facilitate genetic analysis of reciprocal signaling, we have also made
a plasmatocyte-expressing QF2 line that in combination with extant GAL4 drivers
allows independent genetic manipulation of both plasmatocytes and surrounding
tissues, and a GAL80 line that blocks GAL4 drivers from affecting plasmatocytes,
both of which function from the early embryo to the adult.

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 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: The basement membrane (BM) is a thin layer of extracellular matrix (ECM) beneath
nearly all epithelial cell types that is critical for cellular and tissue function.
It is composed of numerous components conserved among all bilaterians [1]; however,
it is unknown how all of these components are generated and subsequently constructed
to form a fully mature BM in the living animal. Although BM formation is thought
to simply involve a process of self-assembly [2], this concept suffers from a
number of logistical issues when considering its construction in vivo. First,
incorporation of BM components appears to be hierarchical [3-5], yet it is unclear
whether their production during embryogenesis must also be regulated in a temporal
fashion. Second, many BM proteins are produced not only by the cells residing
on the BM but also by surrounding cell types [6-9], and it is unclear how large,
possibly insoluble protein complexes [10] are delivered into the matrix. Here
we exploit our ability to live image and genetically dissect de novo BM formation
during Drosophila development. This reveals that there is a temporal hierarchy
of BM protein production that is essential for proper component incorporation.
Furthermore, we show that BM components require secretion by migrating macrophages
(hemocytes) during their developmental dispersal, which is critical for embryogenesis.
Indeed, hemocyte migration is essential to deliver a subset of ECM components
evenly throughout the embryo. This reveals that de novo BM construction requires
a combination of both production and distribution logistics allowing for the timely
delivery of core components.

text: The actin cytoskeleton plays important roles in the formation and internalization
of endocytic vesicles. In yeast, endocytic vesicles move towards early endosomes
along actin cables, however, the molecular machinery regulating interaction between
endocytic vesicles and actin cables is poorly understood. The Eps15-like protein
Pan1p plays a key role in actin-mediated endocytosis and is negatively regulated
by Ark1 and Prk1 kinases. Here we show that pan1 mutated to prevent phosphorylation
at all 18 threonines, pan1-18TA, displayed almost the same endocytic defect as
ark1Δ prk1Δ cells, and contained abnormal actin concentrations including several
endocytic compartments. Early endosomes were highly localized in the actin concentrations
and displayed movement along actin cables. The dephosphorylated form of Pan1p
also caused stable associations between endocytic vesicles and actin cables, and
between endocytic vesicles and endosomes. Thus Pan1 phosphorylation is part of
a novel mechanism that regulates endocytic compartment interactions with each
other and with actin cables.

text: The dynamic assembly and disassembly of actin filaments is essential for the
formation and transport of vesicles during endocytosis. In yeast, two types of
actin structures, namely cortical patches and cytoplasmic cables, play a direct
role in endocytosis, but how their interaction is regulated remains unclear. Here,
we show that Srv2/CAP, an evolutionarily conserved actin regulator, is required
for efficient endocytosis owing to its role in the formation of the actin patches
that aid initial vesicle invagination and of the actin cables that these move
along. Deletion of the SRV2 gene resulted in the appearance of aberrant fragmented
actin cables that frequently moved past actin patches, the sites of endocytosis.
We find that the C-terminal CARP domain of Srv2p is vitally important for the
proper assembly of actin patches and cables; we also demonstrate that the N-terminal
helical folded domain of Srv2 is required for its localization to actin patches,
specifically to the ADP-actin rich region through an interaction with cofilin.
These results demonstrate the in vivo roles of Srv2p in the regulation of the
actin cytoskeleton during clathrin-mediated endocytosis

text: The majority of immune cells in Drosophila melanogaster are plasmatocytes;
they carry out similar functions to vertebrate macrophages, influencing development
as well as protecting against infection and cancer. Plasmatocytes, sometimes referred
to with the broader term of hemocytes, migrate widely during embryonic development
and cycle in the larvae between sessile and circulating positions. Here we discuss
the similarities of plasmatocyte developmental migration and its functions to
that of vertebrate macrophages, considering the recent controversy regarding the
functions of Drosophila PDGF/VEGF related ligands. We also examine recent findings
on the significance of adhesion for plasmatocyte migration in the embryo, as well
as proliferation, trans-differentiation, and tumor responses in the larva. We
spotlight parallels throughout to vertebrate immune responses.

text: Small GTP-binding proteins of the Ras superfamily play diverse roles in intracellular
trafficking. Among them, the Rab, Arf, and Rho families function in successive
steps of vesicle transport, in forming vesicles from donor membranes, directing
vesicle trafficking toward target membranes and docking vesicles onto target membranes.
These proteins act as molecular switches that are controlled by a cycle of GTP
binding and hydrolysis regulated by guanine nucleotide exchange factors (GEFs)
and GTPase-activating proteins (GAPs). In this study we explored the role of GAPs
in the regulation of the endocytic pathway using fluorescently labeled yeast mating
pheromone α-factor. Among 25 non-essential GAP mutants, we found that deletion
of the GLO3 gene, encoding Arf-GAP protein, caused defective internalization of
fluorescently labeled α-factor. Quantitative analysis revealed that glo3Δ cells
show defective α-factor binding to the cell surface. Interestingly, Ste2p, the
α-factor receptor, was mis-localized from the plasma membrane to the vacuole in
glo3Δ cells. Domain deletion mutants of Glo3p revealed that a GAP-independent
function, as well as the GAP activity, of Glo3p is important for both α-factor
binding and Ste2p localization at the cell surface. Additionally, we found that
deletion of the GLO3 gene affects the size and number of Arf1p-residing Golgi
compartments and causes a defect in transport from the TGN to the plasma membrane.
Furthermore, we demonstrated that glo3Δ cells were defective in the late endosome-to-TGN
transport pathway, but not in the early endosome-to-TGN transport pathway. These
findings suggest novel roles for Arf-GAP Glo3p in endocytic recycling of cell
surface proteins.

text: 'The yeast Rab5 homologue, Vps21p, is known to be involved both in the vacuolar
protein sorting (VPS) pathway from the trans-Golgi network to the vacuole, and
in the endocytic pathway from the plasma membrane to the vacuole. However, the
intracellular location at which these two pathways converge remains unclear. In
addition, the endocytic pathway is not completely blocked in yeast cells lacking
all Rab5 genes, suggesting the existence of an unidentified route that bypasses
the Rab5-dependent endocytic pathway. Here we show that convergence of the endocytic
and VPS pathways occurs upstream of the requirement for Vps21p in these pathways.
We also identify a previously unidentified endocytic pathway mediated by the AP-3
complex. Importantly, the AP-3-mediated pathway appears mostly intact in Rab5-disrupted
cells, and thus works as an alternative route to the vacuole/lysosome. We propose
that the endocytic traffic branches into two routes to reach the vacuole: a Rab5-dependent
VPS pathway and a Rab5-independent AP-3-mediated pathway.'
