Inotuzumab ozogamicin for relapse prevention in a boy with Down syndrome and relapsed acute lymphoblastic leukemia.

Inotuzumab ozogamicin (InO), a CD22-directed antibody conjugated to calicheamicin, has demonstrated excellent efficacy in B-cell precursor (BCP) acute lymphoblastic leukemia (ALL). It has been used for patients with relapsed or refractory BCP-ALL as a bridge to allo-HCT. Children with Down syndrome (DS) have an increased risk of BCP-ALL and higher rates of relapse and toxicity, including treatment-related mortality.

Nafamostat mesylate prevents metastasis and dissemination of neuroblastoma through vascular endothelial growth factor inhibition.

Neuroblastoma is a highly malignant disease with a poor prognosis and few treatment options. Despite conventional chemotherapy for neuroblastoma, resistance, invasiveness, and metastatic mobility limit the treatment efficacy. Therefore, it is necessary to develop new strategies for treating neuroblastoma.

Donor-derived M2 macrophages attenuate GVHD after allogeneic hematopoietic stem cell transplantation.

Introduction: Graft-versus-host disease (GVHD) is frequent and fatal complication following allogeneic hematopoietic stem cell transplantation (HSCT) and characteristically involves skin, gut, and liver. Macrophages promote tissue regeneration and mediate immunomodulation. Macrophages are divided into two different phenotypes, classically activated M1 (pro-inflammatory or immune-reactive macrophages) and alternatively activated M2 (anti-inflammatory or immune-suppressive macrophages).

High-resolution mapping of zym, a recessive gene for Zucchini yellow mosaic virus resistance in cucumber.

Using a high-resolution mapping approach, we identified a candidate gene for ZYMV resistance in cucumber. Our findings should assist the development of high-versatility molecular markers for MAS for ZYMV resistance. Zucchini yellow mosaic virus (ZYMV) causes significant disease, which leads to fruit yield loss in cucurbit crops.

Calcineurin inhibitors suppress cytokine production from memory T cells and differentiation of naïve T cells into cytokine-producing mature T cells.

T cells have been classified as belonging to the Th1 or Th2 subsets according to the production of defining cytokines such as IFN-γ and IL-4. The discovery of the Th17 lineage and regulatory T cells shifted the simple concept of the Th1/Th2 balance into a 4-way mechanistic pathway of local and systemic immunological activity. Clinically, the blockage of cytokine signals or non-specific suppression of cytokine predominance by immunosuppressants is the first-line treatment for inflammatory T cell-mediated disorders.
