    Abstract Background: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is associated with late complications that can impair the quality of life (QoL) of patients for years after transplant. The purpose of the present study was to determine the difference in the QoL of adults that underwent allo-HSCT in childhood and adolescence compared with not transplanted adults.
    Methods: In this prospective case-control cross-sectional study, we included patients aged ≥18 years that received an allo-HSCT during childhood or adolescence and subsequently survived at least 2 years after transplantation. The control group consisted of blood donors matched for age and sex. QoL assessment was performed using the Short Form-36 (SF-36) Health Survey, Portuguese version 2.
    Results: Thirty-four transplanted patients and controls were included. 58.8% were male, and the median age at transplant was 13.5 years (range, 4-17 years). The median follow-up was 11.5 years (range, 2.0-23.0 years). The most common late effect was skeletally followed by endocrine complications. Patients with these late complications had the worst QOL in the following dimensions: physical functioning, role physical, bodily pain, general health, and mental health. When compared to the control group, patients had a lower score in two dimensions: physical functioning and role physical.
    Conclusions: Although skeletal and endocrine complications of transplant patients in childhood have an impact on physical functioning, most parameters of QoL of these patients in adulthood are similar to healthy individuals of the same age and gender. Early detection and long-term monitoring of late complications can prevent impairment of the QoL.

    Abstract Failed regeneration of CNS myelin contributes to clinical decline in neuroinflammatory and neurodegenerative diseases, for which there is an unmet therapeutic need. Here we reveal that efficient remyelination requires death of proinflammatory microglia followed by repopulation to a pro-regenerative state. We propose that impaired microglia death and/or repopulation may underpin dysregulated microglia activation in neurological diseases, and we reveal therapeutic targets to promote white matter regeneration.

    Abstract The most prevalent neurological disorders of myelin include perinatal brain injury leading to cerebral palsy in infants and multiple sclerosis in adults. Although these disorders have distinct etiologies, they share a common neuropathological feature of failed progenitor differentiation into myelin-producing oligodendrocytes and lack of myelin, for which there is an unmet clinical need. Here, we reveal that a molecular pathology common to both disorders is dysregulation of activin receptors and that activin receptor signaling is required for the majority of myelin generation in development and following injury. Using a constitutive conditional knockout of all activin receptor signaling in oligodendrocyte lineage cells, we discovered this signaling to be required for myelination via regulation of oligodendrocyte differentiation and myelin compaction. These processes were found to be dependent on the activin receptor subtype Acvr2a, which is expressed during oligodendrocyte differentiation and axonal ensheathment in development and following myelin injury. During efficient myelin regeneration, Acvr2a upregulation was seen to coincide with downregulation of Acvr2b, a receptor subtype with relatively higher ligand affinity; Acvr2b was shown to be dispensable for activin receptor-driven oligodendrocyte differentiation and its overexpression was sufficient to impair the abovementioned ligand-driven responses. In actively myelinating or remyelinating areas of human perinatal brain injury and multiple sclerosis tissue, respectively, oligodendrocyte lineage cells expressing Acvr2a outnumbered those expressing Acvr2b, whereas in non-repairing lesions Acvr2b+ cells were increased. Thus, we propose that following human white matter injury, this increase in Acvr2b expression would sequester ligand and consequently impair Acvr2a-driven oligodendrocyte differentiation and myelin formation. Our results demonstrate dysregulated activin receptor signaling in common myelin disorders and reveal Acvr2a as a novel therapeutic target for myelin generation following injury across the lifespan.
