Why do some neurons die in #neurodegeneration while closely related neighbors survive? This Essay by Dong Won Kim argues that disease resistance may depend on maintenance of a neuron's #cell identity and proposes tests of the model. 🧪 #AcademicSky plos.io/4y7cGbA
Reversible cell-state remodeling vs. identity-maintenance failure in adult neurons.
An adult neuron with stable subtype identity (left) depends on continued operation of four interrelated regulatory components, shown in the inset legend: (1) identity transcription factors; (2) accessible identity enhancers; (3) coherent terminal effector gene modules; and (4) active repression of alternative gene programs belonging to other cell types. Under stress (metabolic, proteostatic, inflammatory, or pathological), the neuron can follow one of two trajectories. (A) In reversible cell-state remodeling, the neuron mounts adaptive responses such as the heat-shock response and the unfolded protein response (UPR), while identity transcription factor activity, enhancer accessibility, terminal effector modules, and repression of alternative programs remain intact. When the stress is removed, the neuron returns to its prior identity state. (B) In identity-maintenance failure, similar stress responses occur, but the regulatory machinery that stabilizes subtype identity itself weakens: identity transcription factor activity falls, identity enhancers lose accessibility, terminal effector modules decohere, and repression of alternative or neighboring-cell programs (orange) fails, allowing those programs to be expressed. After sustained disruption of this machinery, return to the prior identity state may be incomplete, delayed, or unstable even after the initiating stress is removed (broken recovery arrow), and degeneration may follow. The stress-response components are shown at comparable intensity in both panels to emphasize that the framework concerns identity-regulatory outcomes under matched stress exposure, not differences in stress response itself.

🧬 Preprint! 🧵 Our goal is to genetically manipulate every embryonic germ layer to enable high throughput in vivo studies. We previously showed mouse ectoderm can be targeted by amniotic injection, enabling cell-specific manipulation, lineage tracing, and knockouts. But how to reach mesoderm?
Schematic of method developed and application. At embryonic day 7.5, a lentiviral library carrying unique 30-nucleotide barcodes and a fluorescent reporter is injected into the mouse exocoelomic cavity. An E8 embryo cross-section shows that this cavity is continuous with the intraembryonic coelomic cavity, allowing the virus to reach and barcode mesodermal progenitors, including lateral plate and paraxial mesoderm.

People with #OCD recognize that their behavior is irrational but still struggle to inhibit habitual responses. This study that disrupted midfrontal-motor coupling weakens control, helping explain altered motivational bias and reward/punishment approach tendencies. 🧪 #AcademicSky plos.io/4x41iN3
Schematic illustration of regulatory orientations and their clinical relevance. Left (HC): motivational‑bias modulation followed an adaptive complementary pattern, in which enhanced MFC‑lPFC theta phase synchrony was associated with increased weighting of instrumental action values during choice, whereas enhanced MFC‑motor theta phase synchrony was associated with suppression of Pavlovian bias. Right (OCD): modulation of motivational biases was dominated by the MFC‑motor theta phase synchrony pathway, representing a continuous trade‑off between two regulatory profiles rather than discrete subtypes. For descriptive purposes, the schematic illustrates the continuous distribution of these individual regulatory tendencies, which vary between an inhibitory prioritization profile where Pavlovian bias is suppressed at the cost of reduced instrumental weighting, and a value prioritization profile where increased instrumental weighting is accompanied by an amplified Pavlovian bias. The gradient bar at the bottom indicates increasing Yale‑Brown Obsessive Compulsive Scale (Y‑BOCS) obsessive-thought severity from left to right. Greater obsessive‑thought severity predicted a stronger tendency toward the value prioritization orientation.

Mechanics of compression-driven morphogenesis Read this Review from our special issue #DevSIextracellular by Jue Yu Kelly Tan and Chii Jou Chan. journals.biologists.com/dev/article/...
Modulation of tissue dynamics by compressive stress during development. (A) Mouse ovarian follicle growth requires contractile theca cell activity and confinement by the extracellular matrix (ECM) to regulate intrafollicular pressure, which, in turn, balances granulosa cell division (yellow) and death (purple). Arrows indicate compressive stress. (B) The Drosophila leg disc is mechanically confined by the peripodial envelope, which induces compressive stress buildup (arrows) and eventually cell apoptosis at the distal tip. (C) Differential planar growth in the Drosophila wing imaginal disc pouch generates a heterogenous mechanical stress field (arrows), with tensile stresses in the peripheral cells (green) and compressive stress in the central cells (blue). These stresses regulate cell division patterns. (D) During Arabidopsis anther lobe formation, faster growth in the inner lobe (single arrows) causes pressure buildup, causing the lobe epidermis to stretch (double arrows). (E) In the zebrafish follicle, rapid expansion of the future micropyle precursor cell mechanically compresses the adjacent granulosa cells, inducing nuclear export of TAZ in the granulosa cells. This restricts micropyle precursor fate to a single cell through mechanical lateral inhibition. (F) In avian skin follicle patterning, dermal cell aggregation generates compressive forces on the overlying epidermis, inducing β-catenin translocation from the membrane to the nucleus and initiating feather follicle fate specification. (G) Cephalic furrow formation during Drosophila gastrulation serves as a pressure-relieving transient fold that dissipates excess compressive stress generated from tissue collisions between the head and trunk (germ band) extension. (H) Growth under confinement generates internal compressive stresses in Escherichia coli biofilms that drive surface buckling and wrinkle formation.
