  text: 'The development, evolution, and function of the vertebrate central nervous
    system (CNS) can be best studied using diverse model organisms. Amphibians, with
    their unique phylogenetic position at the transition between aquatic and terrestrial
    lifestyles, are valuable for understanding the origin and evolution of the tetrapod
    brain and spinal cord. Their metamorphic developmental transitions and unique
    regenerative abilities also facilitate the discovery of mechanisms for neural
    circuit remodeling and replacement. The genetic toolkit for amphibians, however,
    remains limited, with only a few species having sequenced genomes and a small
    number of transgenic lines available. In mammals, recombinant adeno-associated
    viral vectors (AAVs) have become a powerful alternative to genome modification
    for visualizing and perturbing the nervous system. AAVs are DNA viruses that enable
    neuronal transduction in both developing and adult animals with low toxicity and
    spatial, temporal, and cell-type specificity. However, AAVs have never been shown
    to transduce amphibian cells efficiently. To bridge this gap, we established a
    simple, scalable, and robust strategy to screen AAV serotypes in three distantly-related
    amphibian species: the frogs Xenopus laevis and Pelophylax bedriagae, and the
    salamander Pleurodeles waltl, in both developing larval tadpoles and post-metamorphic
    animals. For each species, we successfully identified at least two AAV serotypes
    capable of infecting the CNS; however, no pan-amphibian serotype was identified,
    indicating rapid evolution of AAV tropism. In addition, we developed an AAV-based
    strategy that targets isochronic cohorts of developing neurons – a critical tool
    for parsing neural circuit assembly. Finally, to enable visualization and manipulation
    of neural circuits, we identified AAV variants for retrograde tracing of neuronal
    projections in adult animals. Our findings expand the toolkit for amphibians to
    include AAVs, establish a generalizable workflow for AAV screening in non-canonical
    research organisms, generate testable hypotheses for the evolution of AAV tropism,
    and lay the foundation for modern cross-species comparisons of vertebrate CNS
    development, function, and evolution. '

  text: 'Vertebrate movement is orchestrated by spinal inter- and motor neurons that,
    together with sensory and cognitive input, produce dynamic motor behaviors. These
    behaviors vary from the simple undulatory swimming of fish and larval aquatic
    species to the highly coordinated running, reaching and grasping of mice, humans
    and other mammals. This variation raises the fundamental question of how spinal
    circuits have changed in register with motor behavior. In simple, undulatory fish,
    exemplified by the lamprey, two broad classes of interneurons shape motor neuron
    output: ipsilateral-projecting excitatory neurons, and commissural-projecting
    inhibitory neurons. An additional class of ipsilateral inhibitory neurons is required
    to generate escape swim behavior in larval zebrafish and tadpoles. In limbed vertebrates,
    a more complex spinal neuron composition is observed. In this review, we provide
    evidence that movement elaboration correlates with an increase and specialization
    of these three basic interneuron types into molecularly, anatomically, and functionally
    distinct subpopulations. We summarize recent work linking neuron types to movement-pattern
    generation across fish, amphibians, reptiles, birds and mammals.'

  text: Amyotrophic lateral sclerosis (ALS) leads to a loss of specific motor neuron
    populations in the spinal cord and cortex. Emerging evidence suggests that interneurons
    may also be affected, but a detailed characterization of interneuron loss and
    its potential impacts on motor neuron loss and disease progression is lacking.
    To examine this issue, the fate of V1 inhibitory neurons during ALS was assessed
    in the ventral spinal cord using the SODG93A mouse model. The V1 population makes
    up ∼30% of all ventral inhibitory neurons, ∼50% of direct inhibitory synaptic
    contacts onto motor neuron cell bodies, and is thought to play a key role in modulating
    motor output, in part through recurrent and reciprocal inhibitory circuits. We
    find that approximately half of V1 inhibitory neurons are lost in SODG93A mice
    at late disease stages, but that this loss is delayed relative to the loss of
    motor neurons and V2a excitatory neurons. We further identify V1 subpopulations
    based on transcription factor expression that are differentially susceptible to
    degeneration in SODG93A mice. At an early disease stage, we show that V1 synaptic
    contacts with motor neuron cell bodies increase, suggesting an upregulation of
    inhibition before V1 neurons are lost in substantial numbers. These data support
    a model in which progressive changes in V1 synaptic contacts early in disease,
    and in select V1 subpopulations at later stages, represent a compensatory upregulation
    and then deleterious breakdown of specific interneuron circuits within the spinal
    cord.

  text: Motor output varies along the rostro-caudal axis of the tetrapod spinal cord.
    At limb levels, ∼60 motor pools control the alternation of flexor and extensor
    muscles about each joint, whereas at thoracic levels as few as 10 motor pools
    supply muscle groups that support posture, inspiration, and expiration. Whether
    such differences in motor neuron identity and muscle number are associated with
    segmental distinctions in interneuron diversity has not been resolved. We show
    that select combinations of nineteen transcription factors that specify lumbar
    V1 inhibitory interneurons generate subpopulations enriched at limb and thoracic
    levels. Specification of limb and thoracic V1 interneurons involves the Hox gene
    Hoxc9 independently of motor neurons. Thus, early Hox patterning of the spinal
    cord determines the identity of V1 interneurons and motor neurons. These studies
    reveal a developmental program of V1 interneuron diversity, providing insight
    into the organization of inhibitory interneurons associated with differential
    motor output.

  text: Neural circuit assembly requires selection of specific cell fates, axonal
    trajectories, and synaptic targets. By analyzing the function of a secreted semaphorin,
    Sema-2b, in Drosophila olfactory receptor neuron (ORN) development, we identified
    multiple molecular and cellular mechanisms that link these events. Notch signaling
    limits Sema-2b expression to ventromedial ORN classes, within which Sema-2b cell-autonomously
    sensitizes ORN axons to external semaphorins. Central-brain-derived Sema-2a and
    Sema-2b attract Sema-2b-expressing axons to the ventromedial trajectory. In addition,
    Sema-2b/PlexB-mediated axon-axon interactions consolidate this trajectory choice
    and promote ventromedial axon-bundle formation. Selecting the correct developmental
    trajectory is ultimately essential for proper target choice. These findings demonstrate
    that Sema-2b couples ORN axon guidance to postsynaptic target neuron dendrite
    patterning well before the final target selection phase, and exemplify how a single
    guidance molecule can drive consecutive stages of neural circuit assembly with
    the help of sophisticated spatial and temporal regulation.

  text: During assembly of the Drosophila olfactory circuit, projection neuron (PN)
    dendrites prepattern the developing antennal lobe before the arrival of axons
    from their presynaptic partners, the adult olfactory receptor neurons (ORNs).
    We previously found that levels of transmembrane Semaphorin-1a, which acts as
    a receptor, instruct PN dendrite targeting along the dorsolateral-ventromedial
    axis. Here we show that two secreted semaphorins, Sema-2a and Sema-2b, provide
    spatial cues for PN dendrite targeting. Sema-2a and Sema-2b proteins are distributed
    in gradients opposing the Sema-1a protein gradient, and Sema-1a binds to Sema-2a-expressing
    cells. In Sema-2a and Sema-2b double mutants, PN dendrites that normally target
    dorsolaterally in the antennal lobe mistarget ventromedially, phenocopying cell-autonomous
    Sema-1a removal from these PNs. Cell ablation, cell-specific knockdown, and rescue
    experiments indicate that secreted semaphorins from degenerating larval ORN axons
    direct dendrite targeting. Thus, a degenerating brain structure instructs the
    wiring of a developing circuit through the repulsive action of secreted semaphorins.

  text: Longitudinal axon fascicles within the Drosophila embryonic CNS provide connections
    between body segments and are required for coordinated neural signaling along
    the anterior-posterior axis. We show here that establishment of select CNS longitudinal
    tracts and formation of precise mechanosensory afferent innervation to the same
    CNS region are coordinately regulated by the secreted semaphorins Sema-2a and
    Sema-2b. Both Sema-2a and Sema-2b utilize the same neuronal receptor, plexin B
    (PlexB), but serve distinct guidance functions. Localized Sema-2b attraction promotes
    the initial assembly of a subset of CNS longitudinal projections and subsequent
    targeting of chordotonal sensory afferent axons to these same longitudinal connectives,
    whereas broader Sema-2a repulsion serves to prevent aberrant innervation. In the
    absence of Sema-2b or PlexB, chordotonal afferent connectivity within the CNS
    is severely disrupted, resulting in specific larval behavioral deficits. These
    results reveal that distinct semaphorin-mediated guidance functions converge at
    PlexB and are critical for functional neural circuit assembly.

  text: By combining gene expression profiling with image registration, Tomer et al.
    (2010) find that the mushroom body of the segmented worm Platynereis dumerilii
    shares many features with the mammalian cerebral cortex. The authors propose that
    the mushroom body and cortex evolved from the same structure in the common ancestor
    of vertebrates and invertebrates.

  text: Gradients of axon guidance molecules instruct the formation of continuous
    neural maps, such as the retinotopic map in the vertebrate visual system. Here
    we show that molecular gradients can also instruct the formation of a discrete
    neural map. In the fly olfactory system, axons of 50 classes of olfactory receptor
    neurons (ORNs) and dendrites of 50 classes of projection neurons (PNs) form one-to-one
    connections at discrete units called glomeruli. We provide expression, loss- and
    gain-of-function data to demonstrate that the levels of transmembrane Semaphorin-1a
    (Sema-1a), acting cell-autonomously as a receptor or part of a receptor complex,
    direct the dendritic targeting of PNs along the dorsolateral to ventromedial axis
    of the antennal lobe. Sema-1a also regulates PN axon targeting in higher olfactory
    centers. Thus, graded expression of Sema-1a contributes to connection specificity
    from ORNs to PNs and then to higher brain centers, ensuring proper representation
    of olfactory information in the brain.

  text: Axon-axon interactions have been implicated in neural circuit assembly, but
    the underlying mechanisms are poorly understood. Here, we show that in the Drosophila
    antennal lobe, early-arriving axons of olfactory receptor neurons (ORNs) from
    the antenna are required for the proper targeting of late-arriving ORN axons from
    the maxillary palp (MP). Semaphorin-1a is required for targeting of all MP but
    only half of the antennal ORN classes examined. Sema-1a acts nonautonomously to
    control ORN axon-axon interactions, in contrast to its cell-autonomous function
    in olfactory projection neurons. Phenotypic and genetic interaction analyses implicate
    PlexinA as the Sema-1a receptor in ORN targeting. Sema-1a on antennal ORN axons
    is required for correct targeting of MP axons within the antennal lobe, while
    interactions amongst MP axons facilitate their entry into the antennal lobe. We
    propose that Sema-1a/PlexinA-mediated repulsion provides a mechanism by which
    early-arriving ORN axons constrain the target choices of late-arriving axons.

  text: 'The Sir2 deacetylase modulates organismal life-span in various species. However,
    the molecular mechanisms by which Sir2 increases longevity are largely unknown.
    We show that in mammalian cells, the Sir2 homolog SIRT1 appears to control the
    cellular response to stress by regulating the FOXO family of Forkhead transcription
    factors, a family of proteins that function as sensors of the insulin signaling
    pathway and as regulators of organismal longevity. SIRT1 and the FOXO transcription
    factor FOXO3 formed a complex in cells in response to oxidative stress, and SIRT1
    deacetylated FOXO3 in vitro and within cells. SIRT1 had a dual effect on FOXO3
    function: SIRT1 increased FOXO3''s ability to induce cell cycle arrest and resistance
    to oxidative stress but inhibited FOXO3''s ability to induce cell death. Thus,
    one way in which members of the Sir2 family of proteins may increase organismal
    longevity is by tipping FOXO-dependent responses away from apoptosis and toward
    stress resistance.'
