Donor cell leukemia is a very rare cause of relapse after allogeneic hematopoietic cell transplantation (alloHCT). Herein, we describe an unprecedented case of donor cell-derived chronic myelomonocytic leukemia (CMML) presenting seven years after a 51-year-old man received a matched-related alloHCT from his 59-year-old brother for T-cell acute lymphoblastic leukemia.

Interleukin-12 (IL-12) is a potent NK cell-stimulating cytokine, but the presence of immunosuppressive myeloid cells such as myeloid-derived suppressor cells (MDSC) can inhibit IL 12-induced NK-cell cytotoxicity. Thus, we hypothesized that trabectedin, a myeloid cell-depleting agent, would improve the efficacy of IL-12 in triple-negative breast cancer (TNBC). In vitro treatment of healthy donor NK cells with trabectedin increased expression of the activation marker CD69 and mRNA expression of T BET (Tbx21), the cytotoxic ligands TRAIL (TNFSF10) and Fas ligand (FASLG) and the dendritic cell (DC)-recruiting chemokine lymphotactin (XCL1).

The aim of this study was to investigate the effect of dental pulp stem cell-derived exosomes (DPSCs-Exos) on the biological behaviour of fibroblasts, particularly on keloid fibroblasts (KFs) and normal skin fibroblasts (NFs), with a view to providing new insights into cellular regenerative medicine. We obtained DPSCs-Exos by ultracentrifugation and co-cultured it with KFs and NFs. We detected its effect on cell proliferation using the CCK-8 assay; cell migration ability by cell scratch and Transwell assays; extracellular matrix synthesis using the hydroxyproline content assay; the expression levels of genes associated with fibrosis by PCR assay; and the expression levels of proteins related to fibrosis in the cells using the Western Blot method.

In asthma, tissue factor (TF) levels are elevated in the lung. In our previous studies using mechanically compressed human bronchial epithelial (HBE) cells, which are a well-defined in vitro model of bronchoconstriction during asthma exacerbations, we detected TF within extracellular vesicles (EVs) released from compressed HBE cells. Here, to better characterize the potential role of this mechanism in asthma, we tested the extent to which the transcriptional regulation of epithelial cell-derived TF varied between donors with and without asthma.

Late-onset Alzheimer's disease (LOAD) is a chronic, multifactorial, and progressive neurodegenerative disease that associates with aging and is highly prevalent in our older population (≥65 years of age). This hypothesis generating this narrative review will examine the important role for the use of sodium thiosulfate (STS) as a possible multi-targeting treatment option for LOAD. Sulfur is widely available in our environment and is responsible for forming organosulfur compounds that are known to be associated with a wide range of biological activities in the brain.

Background And Objective: Adipose-derived mesenchymal stem cell-derived extracellular vesicles (ASCs-Exos) possess angiogenic potential, which can enhance the retention rate of fat grafts. Hypoxic preconditioning can augment their functionality. However, the optimal conditions for hypoxic preconditioning and the specific mechanisms by which it exerts its effects are not well defined.
