Adoptively transferred CD19 chimeric antigen receptor (CAR) T cells have led to impressive clinical outcomes in B cell malignancies. Beyond induction of remission, the persistence CAR-T is required prevent relapse and provide long-term disease control. To improve function persistence, we developed a composite co-stimulatory domain signaling moiety, CD79A/CD40, induce nuclear translocating signal, NF-κB, synergize with other signals function. CD79A/CD40 incorporating CD19CAR-T (CD19.79a.40z)...

TAFRO syndrome have been proposed as a rare variant of Castleman's disease. This article reports case 56-year-old man with who was successfully treated thalidomide in spite the refractoriness to prednisolone and tocilizumab. Thalidomide may be one treatment options for syndrome.

Metabolomics follows the changes in concentrations of endogenous metabolites, which may reflect various disease states as well systemic responses to environmental, therapeutic, or genetic interventions. In this study, we applied metabolomic approaches monitor dynamic plasma and urine compared these metabolite profiles Eisai hyperbilirubinemic rats (EHBR, an animal model cholestasis) with those parent strain EHBR - Sprague-Dawley (SD) order characterize cholestasis pathophysiologically....

An artificial T cell adaptor molecule (ATAM) was generated to improve persistence of receptor (TCR) gene-transduced (TCR-T) cells compared such in a preceding study. ATAMs are gene-modified CD3ζ with the intracellular domain 4-1BB inserted middle CD3ζ. NY-ESO-1 TCR-T transduced an ATAM two separated virus vectors demonstrated superior proliferation upon antigen stimulation. To further develop clinically applicable ATAM-transduced cells, we attempted make single vector transduce TCR and...

Abstract Chimeric antigen receptor T (CAR-T) cells targeting multiple antigens (Ag), may reduce the risk of immune escape following loss target Ag and further increase efficacy treatment. We developed dual-targeting CAR-T that CD19 CD37 Ags evaluated their antitumor effects. CD19/CD37 dual were generated using cotransduction simultaneous gene transfer two types lentiviral vectors transferring CD19CAR or CD37CAR genes, including intracellular domains CD28 CD3ζ signaling domains. These...

We herein present the case of a 30-year-old man who developed recurrent pancreatitis and chronic graft-versus-host disease following unrelated bone marrow transplantation for acute myeloid leukemia (AML) with t(16;21)(p11;q22). Autoimmune was initially suspected due to radiological findings lack response gabexate mesilate antibiotics. An examination specimens successfully obtained via endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) demonstrated invasion AML cells in pancreatic...
