Neonatal brain damage Abstract A specialized neurogenic niche along the ventricles accumulates millions of progenitor cells in the developing brain. After mitosis, fate-committed daughter cells delaminate from this germinative zone.

Considering the high number of cell divisions and A prosztatitis címre vonatkozó jogorvoslat taking place during embryonic development, brain malformations caused by ectopic proliferation of misplaced progenitor cells are relatively rare.

Here, we report that a process we term developmental anoikis distinguishes the pathological detachment of progenitor cells from the normal delamination of daughter neuroblasts in the developing mouse neocortex. We identify the endocannabinoid-metabolizing enzyme abhydrolase domain containing 4 ABHD4 as an essential mediator for the elimination of pathologically detached cells.

Consequently, rapid ABHD4 downregulation is necessary for delaminated daughter neuroblasts to escape from anoikis. Moreover, ABHD4 is required for fetal alcohol-induced apoptosis, but not for the well-established form of developmentally controlled programmed cell death.

These results suggest that ABHD4-mediated developmental anoikis specifically protects the embryonic brain from the consequences of sporadic delamination errors and teratogenic insults.

Download PDF Introduction In the developing brain, radial glia progenitor cells RGPCs spawn various cell types including intermediate progenitor cells, neurons, astrocytes, oligodendrocytes, and ependymal cells 1234.

Following asymmetric cell division at the ventricular surface, the self-renewed RGPCs remain anchored to their neighbors via cadherin-based adherens junctions 56.

This adhesion complex not only serves as a structural stabilizer, but it is also involved in important signaling mechanisms regulating cell cycle, proliferation, and differentiation, indicating that adherens junction assembly and disassembly are tightly coupled to cell fate decisions 789. Accordingly, the non-RGPC-fated daughter cells need to break down their adherens junctions to delaminate from prostate cancer research centre address ventricular wall and to migrate to their functional destinations along the radial scaffold of RGPCs 69prostate cancer research centre address Appropriately timed delamination is critically important for the mature daughter neuroblasts to follow their normal migratory route 6.

In contrast, pathological detachment and abnormal dispersion of RGPCs, which retain their proliferative capacity at ectopic locations, represent a serious risk for brain malformations, such as focal cortical dysplasia or periventricular heterotopia, potentially predisposing to various forms of intellectual disabilities and neurological deficits 111213 Enormous number of cell division events and subsequent delamination steps are required for the generation of hundreds of billions of neurons and other cell types in the brain.

Considering the remarkably low prevalence of congenital brain malformations, it is conceivable to hypothesize that a specific mechanism exists that protects against the consequences of sporadic delamination errors. Yet, how pathologically detached RGPCs are eliminated from the brain parenchyma and the related fundamental question of how fate-committed daughter cells become resistant to this defense mechanism both remain elusive.

Along a similar line of inkontinencia műtét oep, it is plausible to predict that such a protective mechanism should also be activated when pervasive injuries or teratogenic insults damage the adherens junctions in the prenatal brain.

For example, germinal matrix hemorrhage, the most common neurological disease of preterm infants as well as microcephaly-associated environmental teratogens, such as the Zika virus and fetal alcohol exposure are all known to impair cell—cell adhesion in the germinative ventricular zone VZ leading to delamination and subsequent depletion of RGPC pools 151617 However, the molecular link between adherens junction damage and cell death induced by injury or by teratogenic insults remains unknown.

In the present study, we tested the hypothesis that a yet unidentified safeguarding mechanism determines distinct cell fate after normal delamination of daughter cells or pathological detachment of progenitor cells. We demonstrate that adherens junction impairment induces aberrant RGPC delamination, ectopic accumulation, and caspase-mediated apoptosis in the subventricular zone SVZ and VZs, whereas caspase inhibition not only prevents the evoked cell death, but also rescues radial migration into the cortical plate.

Moreover, abhydrolase domain containing 4 ABHD4a serine hydrolase with a yet undefined neurobiological function is identified as a necessary and sufficient mediator for the elimination of pathologically detached cells.

Accordingly, healthy neuroblasts delaminating according to their normal developmental program switch off ABHD4 expression in parallel with their neurogenic commitment. ABHD4 is not required for the canonical form of developmentally controlled programmed cell death in the embryonic neocortex indicating that its function is specifically associated with pathological insults.

Doctors may have found secretive new organs in the center of your head By Katherine J. Wu The New York Times Oct 20, at AM After millenniums of careful slicing and dicing, it might seem as though scientists have figured out human anatomy. A few dozen organs, a couple hundred bones and connective tissue to tie it all together. But despite centuries of scrutiny, the body is still capable of surprising scientists.

In agreement with this possibility, our findings elucidate that ABHD4 is also essential for prenatal alcohol exposure-induced apoptosis providing insights into the mechanisms underlying cell death associated with fetal alcohol syndrome.

Results Pathological RGPC detachment triggers developmental anoikis N-cadherin encoded by the Cdh2 gene is the major molecular component of the adherens junction belt along the ventricular wall in the developing mammalian brain 5. To interfere with cadherin-based cell-cell adhesions, we carried prostate cancer research centre address in utero electroporation of a dominant-negative version of N-cadherin ΔnCdh2-GFP into the lateral ventricles at embryonic day We exploited this conditional and sparse adherens junction injury protocol instead of the global loss-of-function approaches to restrict the effects in time and space to a selected prostate cancer research centre address of RGPCs and to avoid potential compensatory mechanisms that are more likely to come into play upon systems-level perturbations.

Confocal and STORM super-resolution microscopy revealed a striking specificity of this experimental manipulation as basal processes of electroporated RGPCs still reached the basal surface in ΔnCdh2-electroporated cortices Fig. Moreover, the morphology of the basal endfeet at the pial prostate cancer research centre address Fig.

As a result of the adherens junction disruption, the detached RGPCs delaminated from the ventricular surface and accumulated in the SVZ. Most of these pathologically detached progenitor cells retained PAX6 transcription factor expression, a marker of RGPCs 19 even outside of the ventricular germinative niche Fig. High-power fluorescent micrographs of the ventricular zone VZ show the adherens junction belt white arrowheads around the ventricle V.

High-power images g, j demonstrate that the attachment prostate cancer research centre address the basal endfeet of RGPCs to the pial surface is not affected directly by the disruption of cadherin-based adherens junctions at the ventricular surface.

Full size image In hogy nincs prostatitis gyakorlás to investigate the fate of these pathologically detached RGPCs, we next tested whether cell death is also induced by adherens junction disruption. In addition, administration of the pan-caspase inhibitor Z-VAD-FMK fully prevented the increase in cell death evoked by adherens junction disruption Fig.

In contrast, basal cell death levels remained unaffected demonstrating that pathological detachment specifically triggers a caspase-dependent apoptotic process Fig. These observations reinforce the idea that a specific cell death mechanism exists to eradicate pathologically detached progenitor cells in the developing neocortex, and this mechanism must be prostate cancer research centre address off in normally delaminating fate-comitted daughter cells to permit their migration to their functional destinations.

We termed this process developmental anoikis, because it conceptually resembles the specific form of apoptosis of epithelial cells induced by the loss of cell anchorage 20 Anoikis has primarily been implicated as a protective mechanism in tumor biology, and pathologically detached tumor cells need to develop resistance to anoikis to become able to invade distant organs during metastasis formation Graphs show box-and-whisker plots including minima, maxima, and median values, lower and upper quartiles with single values.
