Hemoglobin F synthesis is not restricted to fetal erythropoietic organs during extramedullary hematopoiesis

Haematologica, 2002
We investigated whether the anatomic distribution of hematopoietic cells determines the type of hemoglobin produced in patients with extramedullary hematopoiesis (EMH).Fetal hemoglobin (HbF) production is not restricted to fetal erythropoietic organs ...

Improved Fetal Hemoglobin With mTOR Inhibitor–Based Immunosuppression in a Kidney Transplant Recipient With Sickle Cell Disease

American Journal of Transplantation, 2017
Fetal hemoglobin induction is a key point in the management of sickle cell disease (SCD). We report the case of a kidney transplant recipient with SCD who was treated with everolimus, a mammalian target of rapamycin inhibitor.

Biomimetic Hydrogel System Targeting S100A8 Centered Neuroimmune Crosstalk and Hypoxia Induced Neuronal Injury

Advanced Science, EarlyView.
A biomimetic hydrogel (HPC@Gel) was developed for traumatic brain injury repair by combining oxygen‐carrying hemoglobin nanoparticles and anti‐inflammatory carbon quantum dots within a brain‐like matrix. The system alleviated hypoxia, reduced harmful neuroimmune signaling, protected neurons, supported neural regeneration, and improved neurological and ...

THBS1+ Macrophages Exacerbate Modic Changes via SDC4‐Dependent Activation of NLRP3 Inflammasome

Advanced Science, EarlyView.
The illustration of THBS1+ macrophages exacerbate MCs via SDC4‐dependent activation of the NLRP3 inflammasome. THBS1+ macrophage subpopulation was identified in MCs through single‐cell RNA sequencing. C. acnes and its metabolites activate THBS1 expression in macrophages via the TLR signaling pathway.

Diagnóstico não invasivo da anemia fetal pela medida do pico de velocidade sistólica na dopplervelocimetria da artéria cerebral média Noninvasive fetal anemia diagnosis by middle cerebral artery peak systolic velocity waveform measurement

Revista Brasileira de Ginecologia e Obstetrícia, 2004
OBJETIVO: avaliar se existe associação entre a medida do pico de velocidade sistólica (PVS) na dopplervelocimetria da artéria cerebral média (ACM) e a concentração de hemoglobina fetal e determinar a sua capacidade diagnóstica.

Transcription factors LRF and BCL11A independently repress expression of fetal hemoglobin

Science, 2016
Reactivating the fetal globin gene Mutation of adult-type globin genes causes sickle cell disease and thalassemia. Although treating these hemoglobinopathies with gene therapy is possible, there is a pressing need for pharmacologic approaches to treat ...

A Hydrogen Sulfide–Releasing Dynamic Hydrogel Modulates Coordinated Neurovascular, Immune, and Angiogenic Responses for Scar‐Suppressed Diabetic Wound Repair

Advanced Science, EarlyView.
ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...

Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

Advanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Direct Promoter Repression by BCL11A Controls the Fetal to Adult Hemoglobin Switch

Cell, 2018
Fetal hemoglobin (HbF, α2γ2) level is genetically controlled and modifies severity of adult hemoglobin (HbA, α2β2) disorders, sickle cell disease and β-thalassemia. Common genetic variation affects expression of BCL11A, a regulator of HbF silencing.

Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, EarlyView.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...
