Human CD34 < sup > + < /sup > -derived complete plasmacytoid and conventional dendritic cell vaccine effectively induces antigen-specific CD8 < sup > + < /sup > T cell and NK cell responses in vitro and in vivo
In this study, we aimed to dissect the phenotypic identity of these non-DCs and their potential immune modulatory functions on the potency of cDCs and pDCs in stimulating tumor-reactive CD8+ T and NK cell responses, in order to obtain rationale for clinical translation of our DC-complete vaccine. The non-DC compartment was heterogeneous and comprised of myeloid progenitors and (immature) granulocyte- and monocyte-like cells. Importantly, non-DCs potentiated toll-like receptor-induced DC maturation, as reflected by increased expression of co-stimulatory molecules and enhanced cDC-derived IL-12 and pDC-derived IFN-α product...

Polysaccharide-Based Composite Hydrogel with Hierarchical Microstructure for Enhanced Vascularization and Skull Regeneration
Biomacromolecules. 2023 Sep 20. doi: 10.1021/acs.biomac.3c00655. Online ahead of print.ABSTRACTCritical-size skull defects caused by trauma, infection, and tumor resection raise great demands for efficient bone substitutes. Herein, a hybrid cross-linked hierarchical microporous hydrogel scaffold (PHCLS) was successfully assembled by a multistep procedure, which involved (i) the preparation of poly(lactic-co-glycolic)/nanohydroxyapatite (PLGA-HAP) porous microspheres, (ii) embedding the spheres in a solution of dopamine-modified hyaluronic acid and collagen I (Col I) and cross-linking via dopamine polyphenols binding to (i)...

Bone marrow mesenchymal stem cell exosome-derived lncRNA TUC339 influences the progression of osteoarthritis by regulating synovial macrophage polarization and chondrocyte apoptosis
In this study, we found that TUC339 was lower in the research group than in the control group and it was negatively correlated with IL-6, IL-8 and TNF-α. Prognosis TUC339 was lower in patients with recurrent OA than in those without recurrence, and ROC analysis manifested that TUC339 had a better predictive value for recurrence of OA. Phenotypic identification revealed elevated expression of CD29 and CD44 in BMSCs and TSG101, CD63 and CD81 in BMSCs-exosome (BMSCs-exo), with a stem cell versus exosome phenotype. Finally, animal experiments improved significantly in joint injury in the BMSCs-exo and TUC339-overexpression ve...

The Warburg effect on radioresistance: Survival beyond growth
Biochim Biophys Acta Rev Cancer. 2023 Sep 17:188988. doi: 10.1016/j.bbcan.2023.188988. Online ahead of print.ABSTRACTThe Warburg effect is a phenomenon in which cancer cells rely primarily on glycolysis rather than oxidative phosphorylation, even in the presence of oxygen. Although evidence of its involvement in cell proliferation has been discovered, the advantages of the Warburg effect in cancer cell survival under treatment have not been fully elucidated. In recent years, the metabolic characteristics of radioresistant cancer cells have been evaluated, enabling an extension of the original concept of the Warburg effect....

Newborn screening for severe combined immunodeficiencies (SCID) in Germany
Bundesgesundheitsblatt Gesundheitsforschung Gesundheitsschutz. 2023 Sep 19. doi: 10.1007/s00103-023-03773-6. Online ahead of print.ABSTRACTPatients with a severe combined immunodeficiency (SCID) harbor genetic mutations disrupting T cell immunity and hence suffer severe, life-threatening infections or manifestations of immune dysregulation within the first months of their life. The only cure is to correct their immune system, usually by means of hematopoietic stem cell transplantation (HSCT). Pilot studies and national programs in the United States and in European countries have shown that patients can be identified at an ...

The Role of Mesenchymal Stem/Stromal Cells Secretome in Macrophage Polarization: Perspectives on Treating Inflammatory Diseases
Curr Stem Cell Res Ther. 2023 Sep 4. doi: 10.2174/1574888X18666230811093101. Online ahead of print.ABSTRACTMesenchymal stem/stromal cells (MSCs) have exhibited potential for treating multiple inflammation- related diseases (IRDs) due to their easy acquisition, unique immunomodulatory and tissue repair properties, and immune-privileged characteristics. It is worth mentioning that MSCs release a wide array of soluble bioactive components in the secretome that modulate host innate and adaptive immune responses and promote the resolution of inflammation. As the first line of defense, macrophages exist throughout the entire inf...

Effect of miR-18a-5p, miR-19a-3p, and miR-20a-5p on < em > In Vitro < /em > Cardiomyocyte Differentiation of Human Endometrium Tissue-Derived Stem Cells Through Regulation of Smad4 Expression
CONCLUSION: Our results indicate that miR-18a-5p, miR-19a-3p, and miR-20a-5p are involved in the cardiac differentiation propensity of hEMSCs potentially by regulation of Smad levels. Although, more mechanistic experiments are required to confirm this idea.PMID:37724150 | PMC:PMC10505458 | DOI:10.52547/rbmb.12.1.136

Fibronectin-coated polyurethane meniscal scaffolding supplemented with MSCs improves scaffold integration and proteoglycan production in a rabbit model
CONCLUSION: In a rabbit model at 12 weeks, the adhesion of MSCs to a FN-coated PU scaffold improves scaffold integration, proteoglycan production and the characteristics of the new meniscal-like tissue obtained when compared to a non-supplemented scaffold. This fact could be a major step toward improving the adhesion of the MSCs to meniscal scaffolds and, consequently, the obtention of better quality meniscal tissue.PMID:37725106 | DOI:10.1007/s00167-023-07562-1

Human umbilical cord mesenchymal stem cells-derived exosomes exert anti-inflammatory effects on osteoarthritis chondrocytes
Aging (Albany NY). 2023 Sep 18;15. doi: 10.18632/aging.205034. Online ahead of print.ABSTRACTInflammation of chondrocytes plays a critical role in the occurrence and development of osteoarthritis (OA). Recent evidence indicated exosomes derived from mesenchymal stem cells (MSCs-Exos) exhibit excellent anti-inflammatory ability in many troublesome inflammatory diseases including OA. In the present study, we aimed to explore the role of human umbilical cord-derived MSCs-Exos (hUC-MSCs-Exos) in treating the inflammation of chondrocytes and its related mechanisms. Ultracentrifugation was applied to isolate hUC-MSCs-Exos from t...

Heterogeneity in RAG 1/2 Deficiency: 35 Cases From A Single Center
This study aimed to define the clinical/laboratory spectrum of RAG1/2 deficiency. We retrospectively reviewed the clinical/laboratory data of 35 patients, grouped them as severe combined immunodeficiency (SCID), Omenn Syndrome (OS), and delayed-onset combined immunodeficiency (CID) and reported nine novel mutations. Male/female ratio was 23/12. Median age of clinical manifestations was 1 months (mo) (0.5-2), 2 mo (1.25-5), and 14 mo (3.63-27), age at diagnosis was 4 mo (3-6), 4.5 mo (2.5-9.75), and 27 mo (14.5-70) in SCID (n=25;71.4%), OS (n=5;14.3%), and CID (n=5;14.3%) patients, respectively. Common clinical manifestatio...
