text: 'Extrasynaptic actions of glutamate are limited by high-affinity transporters
expressed by perisynaptic astroglial processes (PAPs): this helps maintain point-to-point
transmission in excitatory circuits. Memory formation in the brain is associated
with synaptic remodeling, but how this affects PAPs and therefore extrasynaptic
glutamate actions is poorly understood. Here, we used advanced imaging methods,
in situ and in vivo, to find that a classical synaptic memory mechanism, long-term
potentiation (LTP), triggers withdrawal of PAPs from potentiated synapses. Optical
glutamate sensors combined with patch-clamp and 3D molecular localization reveal
that LTP induction thus prompts spatial retreat of astroglial glutamate transporters,
boosting glutamate spillover and NMDA-receptor-mediated inter-synaptic cross-talk.
The LTP-triggered PAP withdrawal involves NKCC1 transporters and the actin-controlling
protein cofilin but does not depend on major Ca2+-dependent cascades in astrocytes.
We have therefore uncovered a mechanism by which a memory trace at one synapse
could alter signal handling by multiple neighboring connections.'

text: "A major challenge in neuroscience research is to dissect the circuits that
orchestrate behavior in health and disease. Proteins from a wide range of non-mammalian
species, such as microbial opsins, have been successfully transplanted to specific
neuronal targets to override their natural communication patterns. The goal of
our work is to manipulate synaptic communication in a manner that closely incorporates
the functional intricacies of synapses by preserving temporal encoding (i.e. the
firing pattern of the presynaptic neuron) and connectivity (i.e. target specific
synapses rather than specific neurons). Our strategy to achieve this goal builds
on the use of non-mammalian transplants to create a synthetic synapse. The mode
of modulation comes from pre-synaptic uptake of a synthetic neurotransmitter (SN)
into synaptic vesicles by means of a genetically targeted transporter selective
for the SN. Upon natural vesicular release, exposure of the SN to the synaptic
cleft will modify the post-synaptic potential through an orthogonal ligand gated
ion channel. To achieve this goal we have functionally characterized a mixed cationic
methionine-gated ion channel from Arabidopsis thaliana, designed a method to functionally
characterize a synthetic transporter in isolated synaptic vesicles without the
need for transgenic animals, identified and extracted multiple prokaryotic uptake
systems that are substrate specific for methionine (Met), and established a primary/cell
line co-culture system that would allow future combinatorial testing of this orthogonal
transmitter-transporter-channel trifecta.\r\nSynthetic synapses will provide a
unique opportunity to manipulate synaptic communication while maintaining the
electrophysiological integrity of the pre-synaptic cell. In this way, information
may be preserved that was generated in upstream circuits and that could be essential
for concerted function and information processing."

text: "Background\r\nSynaptic vesicles (SVs) are an integral part of the neurotransmission
machinery, and isolation of SVs from their host neuron is necessary to reveal
their most fundamental biochemical and functional properties in in vitro assays.
Isolated SVs from neurons that have been genetically engineered, e.g. to introduce
genetically encoded indicators, are not readily available but would permit new
insights into SV structure and function. Furthermore, it is unclear if cultured
neurons can provide sufficient starting material for SV isolation procedures.\r\n\r\nNew
method\r\nHere, we demonstrate an efficient ex vivo procedure to obtain functional
SVs from cultured rat cortical neurons after genetic engineering with a lentivirus.\r\n\r\nResults\r\nWe
show that ∼108 plated cortical neurons allow isolation of suitable SV amounts
for functional analysis and imaging. We found that SVs isolated from cultured
neurons have neurotransmitter uptake comparable to that of SVs isolated from intact
cortex. Using total internal reflection fluorescence (TIRF) microscopy, we visualized
an exogenous SV-targeted marker protein and demonstrated the high efficiency of
SV modification.\r\n\r\nComparison with existing methods\r\nObtaining SVs from
genetically engineered neurons currently generally requires the availability of
transgenic animals, which is constrained by technical (e.g. cost and time) and
biological (e.g. developmental defects and lethality) limitations.\r\n\r\nConclusions\r\nThese
results demonstrate the modification and isolation of functional SVs using cultured
neurons and viral transduction. The ability to readily obtain SVs from genetically
engineered neurons will permit linking in situ studies to in vitro experiments
in a variety of genetic contexts."

text: Non-canonical Wnt signaling plays a central role for coordinated cell polarization
and directed migration in metazoan development. While spatiotemporally restricted
activation of non-canonical Wnt-signaling drives cell polarization in epithelial
tissues, it remains unclear whether such instructive activity is also critical
for directed mesenchymal cell migration. Here, we developed a light-activated
version of the non-canonical Wnt receptor Frizzled 7 (Fz7) to analyze how restricted
activation of non-canonical Wnt signaling affects directed anterior axial mesendoderm
(prechordal plate, ppl) cell migration within the zebrafish gastrula. We found
that Fz7 signaling is required for ppl cell protrusion formation and migration
and that spatiotemporally restricted ectopic activation is capable of redirecting
their migration. Finally, we show that uniform activation of Fz7 signaling in
ppl cells fully rescues defective directed cell migration in fz7 mutant embryos.
Together, our findings reveal that in contrast to the situation in epithelial
cells, non-canonical Wnt signaling functions permissively rather than instructively
in directed mesenchymal cell migration during gastrulation.

text: Optogenetics enables the spatio-temporally precise control of cell and animal
behavior. Many optogenetic tools are driven by light-controlled protein–protein
interactions (PPIs) that are repurposed from natural light-sensitive domains (LSDs).
Applying light-controlled PPIs to new target proteins is challenging because it
is difficult to predict which of the many available LSDs, if any, will yield robust
light regulation. As a consequence, fusion protein libraries need to be prepared
and tested, but methods and platforms to facilitate this process are currently
not available. Here, we developed a genetic engineering strategy and vector library
for the rapid generation of light-controlled PPIs. The strategy permits fusing
a target protein to multiple LSDs efficiently and in two orientations. The public
and expandable library contains 29 vectors with blue, green or red light-responsive
LSDs, many of which have been previously applied ex vivo and in vivo. We demonstrate
the versatility of the approach and the necessity for sampling LSDs by generating
light-activated caspase-9 (casp9) enzymes. Collectively, this work provides a
new resource for optical regulation of a broad range of target proteins in cell
and developmental biology.

text: G-protein-coupled receptors (GPCRs) form the largest receptor family, relay
environmental stimuli to changes in cell behavior and represent prime drug targets.
Many GPCRs are classified as orphan receptors because of the limited knowledge
on their ligands and coupling to cellular signaling machineries. Here, we engineer
a library of 63 chimeric receptors that contain the signaling domains of human
orphan and understudied GPCRs functionally linked to the light-sensing domain
of rhodopsin. Upon stimulation with visible light, we identify activation of canonical
cell signaling pathways, including cAMP-, Ca2+-, MAPK/ERK-, and Rho-dependent
pathways, downstream of the engineered receptors. For the human pseudogene GPR33,
we resurrect a signaling function that supports its hypothesized role as a pathogen
entry site. These results demonstrate that substituting unknown chemical activators
with a light switch can reveal information about protein function and provide
an optically controlled protein library for exploring the physiology and therapeutic
potential of understudied GPCRs.

text: 'A major challenge in neuroscience research is to dissect the circuits that
orchestrate behavior in health and disease. Proteins from a wide range of non-mammalian
species, such as microbial opsins, have been successfully transplanted to specific
neuronal targets to override their natural communication patterns. The goal of
our work is to manipulate synaptic communication in a manner that closely incorporates
the functional intricacies of synapses by preserving temporal encoding (i.e. the
firing pattern of the presynaptic neuron) and connectivity (i.e. target specific
synapses rather than specific neurons). Our strategy to achieve this goal builds
on the use of non-mammalian transplants to create a synthetic synapse. The mode
of modulation comes from pre-synaptic uptake of a synthetic neurotransmitter (SN)
into synaptic vesicles by means of a genetically targeted transporter selective
for the SN. Upon natural vesicular release, exposure of the SN to the synaptic
cleft will modify the post-synaptic potential through an orthogonal ligand gated
ion channel. To achieve this goal we have functionally characterized a mixed cationic
methionine-gated ion channel from Arabidopsis thaliana, designed a method to functionally
characterize a synthetic transporter in isolated synaptic vesicles without the
need for transgenic animals, identified and extracted multiple prokaryotic uptake
systems that are substrate specific for methionine (Met), and established a primary/cell
line co-culture system that would allow future combinatorial testing of this orthogonal
transmitter-transporter-channel trifecta. Synthetic synapses will provide a unique
opportunity to manipulate synaptic communication while maintaining the electrophysiological
integrity of the pre-synaptic cell. In this way, information may be preserved
that was generated in upstream circuits and that could be essential for concerted
function and information processing. '

text: Fluorescent sensors are an essential part of the experimental toolbox of the
life sciences, where they are used ubiquitously to visualize intra- and extracellular
signaling. In the brain, optical neurotransmitter sensors can shed light on temporal
and spatial aspects of signal transmission by directly observing, for instance,
neurotransmitter release and spread. Here we report the development and application
of the first optical sensor for the amino acid glycine, which is both an inhibitory
neurotransmitter and a co-agonist of the N-methyl-d-aspartate receptors (NMDARs)
involved in synaptic plasticity. Computational design of a glycine-specific binding
protein allowed us to produce the optical glycine FRET sensor (GlyFS), which can
be used with single and two-photon excitation fluorescence microscopy. We took
advantage of this newly developed sensor to test predictions about the uneven
spatial distribution of glycine in extracellular space and to demonstrate that
extracellular glycine levels are controlled by plasticity-inducing stimuli.

text: "The aim of this thesis was the development of new strategies for optical
and optogenetic control of proliferative and pro-survival signaling, and characterizing
them from the molecular mechanism up to cellular effects. These new light-based
methods have unique features, such as red light as an activator, or the avoidance
of gene delivery, which enable to overcome current limitations, such as light
delivery to target tissues and feasibility as therapeutic approach. A special
focus was placed on implementing these new light-based approaches in pancreatic
β-cells, as β-cells are the key players in diabetes and especially their loss
in number negatively affects disease progression. Currently no treatment options
are available to compensate the lack of functional β-cells in diabetic patients.\r\nIn
a first approach, red-light-activated growth factor receptors, in particular receptor
tyrosine kinases were engineered and characterized. Receptor activation with light
allows spatio-temporal control compared to ligand-based activation, and especially
red light exhibits deeper tissue penetration than other wavelengths of the visible
spectrum. Red-light-activated receptor tyrosine kinases robustly activated major
growth factor related signaling pathways with a high temporal resolution. Moreover,
the remote activation of the proliferative MAPK/Erk pathway by red-light-activated
receptor tyrosine kinases in a pancreatic β-cell line was also achieved, through
one centimeter thick mouse tissue. Although red-light-activated receptor tyrosine
kinases are particularly attractive for applications in animal models due to the
deep tissue penetration of red light, a drawback, especially with regard to translation
into humans, is the requirement of gene therapy.\r\nIn a second approach an endogenous
light-sensitive mechanism was identified and its potential to promote proliferative
and pro-survival signals was explored, towards light-based tissue regeneration
without the need for gene transfer. Blue-green light illumination was found to
be sufficient for the activation of proliferation and survival promoting signaling
pathways in primary pancreatic murine and human islets. Blue-green light also
led to an increase in proliferation of primary islet cells, an effect which was
shown to be mostly β-cell specific in human islets. Moreover, it was demonstrated
that this approach of pancreatic β-cell expansion did not have any negative effect
on the β-cell function, in particular on their insulin secretion capacity. In
contrast, a trend for enhanced insulin secretion under high glucose conditions
after illumination was detected. In order to unravel the detailed characteristics
of this endogenous light-sensitive mechanism, the precise light requirements were
determined. In addition, the expression of light sensing proteins, OPN3 and rhodopsin,
was detected. The observed effects were found to be independent of handling effects
such as temperature differences and cytochrome c oxidase dependent ATP increase,
but they were found to be enhanced through the knockout of OPN3. The exact mechanism
of how islets cells sense light and the identity of the photoreceptor remains
unknown.\r\nSummarized two new light-based systems with unique features were established
that enable the activation of proliferative and pro-survival signaling pathways.
While red-light-activated receptor tyrosine kinases open a new avenue for optogenetics
research, by allowing non-invasive control of signaling in vivo, the identified
endogenous light-sensitive mechanism has the potential to be the basis of a gene
therapy-free therapeutical approach for light-based β-cell expansion."

text: Small molecule biosensors based on Forster resonance energy transfer (FRET)
enable small molecule signaling to be monitored with high spatial and temporal
resolution in complex cellular environments. FRET sensors can be constructed by
fusing a pair of fluorescent proteins to a suitable recognition domain, such as
a member of the solute-binding protein (SBP) superfamily. However, naturally occurring
SBPs may be unsuitable for incorporation into FRET sensors due to their low thermostability,
which may preclude imaging under physiological conditions, or because the positions
of their N- and C-termini may be suboptimal for fusion of fluorescent proteins,
which may limit the dynamic range of the resulting sensors. Here, we show how
these problems can be overcome using ancestral protein reconstruction and circular
permutation. Ancestral protein reconstruction, used as a protein engineering strategy,
leverages phylogenetic information to improve the thermostability of proteins,
while circular permutation enables the termini of an SBP to be repositioned to
maximize the dynamic range of the resulting FRET sensor. We also provide a protocol
for cloning the engineered SBPs into FRET sensor constructs using Golden Gate
assembly and discuss considerations for in situ characterization of the FRET sensors.

text: Biosensors that exploit Forster resonance energy transfer (FRET) can be used
to visualize biological and physiological processes and are capable of providing
detailed information in both spatial and temporal dimensions. In a FRET-based
biosensor, substrate binding is associated with a change in the relative positions
of two fluorophores, leading to a change in FRET efficiency that may be observed
in the fluorescence spectrum. As a result, their design requires a ligand-binding
protein that exhibits a conformational change upon binding. However, not all ligand-binding
proteins produce responsive sensors upon conjugation to fluorescent proteins or
dyes, and identifying the optimum locations for the fluorophores often involves
labor-intensive iterative design or high-throughput screening. Combining the genetic
fusion of a fluorescent protein to the ligand-binding protein with site-specific
covalent attachment of a fluorescent dye can allow fine control over the positions
of the two fluorophores, allowing the construction of very sensitive sensors.
This relies upon the accurate prediction of the locations of the two fluorophores
in bound and unbound states. In this chapter, we describe a method for computational
identification of dye-attachment sites that allows the use of cysteine modification
to attach synthetic dyes that can be paired with a fluorescent protein for the
purposes of creating FRET sensors.

text: The optogenetic revolution enabled spatially-precise and temporally-precise
control over protein function, signaling pathway activation, and animal behavior
with tremendous success in the dissection of signaling networks and neural circuits.
Very recently, optogenetic methods have been paired with optical reporters in
novel drug screening platforms. In these all-optical platforms, light remotely
activated ion channels and kinases thereby obviating the use of electrophysiology
or reagents. Consequences were remarkable operational simplicity, throughput,
and cost-effectiveness that culminated in the identification of new drug candidates.
These blueprints for all-optical assays also revealed potential pitfalls and inspire
all-optical variants of other screens, such as those that aim at better understanding
dynamic drug action or orphan protein function.

text: Optogenetics and photopharmacology provide spatiotemporally precise control
over protein interactions and protein function in cells and animals. Optogenetic
methods that are sensitive to green light and can be used to break protein complexes
are not broadly available but would enable multichromatic experiments with previously
inaccessible biological targets. Herein, we repurposed cobalamin (vitamin B12)
binding domains of bacterial CarH transcription factors for green-light-induced
receptor dissociation. In cultured cells, we observed oligomerization-induced
cell signaling for the fibroblast growth factor receptor 1 fused to cobalamin-binding
domains in the dark that was rapidly eliminated upon illumination. In zebrafish
embryos expressing fusion receptors, green light endowed control over aberrant
fibroblast growth factor signaling during development. Green-light-induced domain
dissociation and light-inactivated receptors will critically expand the optogenetic
toolbox for control of biological processes.

text: During metazoan development, the temporal pattern of morphogen signaling is
critical for organizing cell fates in space and time. Yet, tools for temporally
controlling morphogen signaling within the embryo are still scarce. Here, we developed
a photoactivatable Nodal receptor to determine how the temporal pattern of Nodal
signaling affects cell fate specification during zebrafish gastrulation. By using
this receptor to manipulate the duration of Nodal signaling in vivo by light,
we show that extended Nodal signaling within the organizer promotes prechordal
plate specification and suppresses endoderm differentiation. Endoderm differentiation
is suppressed by extended Nodal signaling inducing expression of the transcriptional
repressor goosecoid (gsc) in prechordal plate progenitors, which in turn restrains
Nodal signaling from upregulating the endoderm differentiation gene sox17 within
these cells. Thus, optogenetic manipulation of Nodal signaling identifies a critical
role of Nodal signaling duration for organizer cell fate specification during
gastrulation.

text: Optical sensors based on the phenomenon of Förster resonance energy transfer
(FRET) are powerful tools that have advanced the study of small molecules in biological
systems. However, sensor construction is not trivial and often requires multiple
rounds of engineering or an ability to screen large numbers of variants. A method
that would allow the accurate rational design of FRET sensors would expedite the
production of biologically useful sensors. Here, we present Rangefinder, a computational
algorithm that allows rapid in silico screening of dye attachment sites in a ligand-binding
protein for the conjugation of a dye molecule to act as a Förster acceptor for
a fused fluorescent protein. We present three ratiometric fluorescent sensors
designed with Rangefinder, including a maltose sensor with a dynamic range of
>300% and the first sensors for the most abundant sialic acid in human cells,
N-acetylneuraminic acid. Provided a ligand-binding protein exists, it is our expectation
that this model will facilitate the design of an optical sensor for any small
molecule of interest.

text: 'Optogenetics and photopharmacology enable the spatio-temporal control of
cell and animal behavior by light. Although red light offers deep-tissue penetration
and minimal phototoxicity, very few red-light-sensitive optogenetic methods are
currently available. We have now developed a red-light-induced homodimerization
domain. We first showed that an optimized sensory domain of the cyanobacterial
phytochrome 1 can be expressed robustly and without cytotoxicity in human cells.
We then applied this domain to induce the dimerization of two receptor tyrosine
kinases—the fibroblast growth factor receptor 1 and the neurotrophin receptor
trkB. This new optogenetic method was then used to activate the MAPK/ERK pathway
non-invasively in mammalian tissue and in multicolor cell-signaling experiments.
The light-controlled dimerizer and red-light-activated receptor tyrosine kinases
will prove useful to regulate a variety of cellular processes with light. Go deep
with red: The sensory domain (S) of the cyanobacterial phytochrome 1 (CPH1) was
repurposed to induce the homodimerization of proteins in living cells by red light.
By using this domain, light-activated protein kinases were engineered that can
be activated orthogonally from many fluorescent proteins and through mammalian
tissue. Pr/Pfr=red-/far-red-absorbing state of CPH1.'

text: High-throughput live-cell screens are intricate elements of systems biology
studies and drug discovery pipelines. Here, we demonstrate an optogenetics-assisted
method that avoids the need for chemical activators and reporters, reduces the
number of operational steps and increases information content in a cell-based
small-molecule screen against human protein kinases, including an orphan receptor
tyrosine kinase. This blueprint for all-optical screening can be adapted to many
drug targets and cellular processes.
