Introduction: Treatment options for relapsed or refractory (r/r) B-cell non-Hodgkin lymphomas (B-NHL) have broadened towards T-cell engaging therapies, including CD19-targeting chimeric antigen receptor T-cells (CD19-CAR) and bispecific antibodies (CD19-BsAb). Although CD19-CAR CD19-BsAb induce durable responses in some r/r B-NHL patients, response remains heterogenous a significant proportion ...

The production of factor VIII inhibitor antibodies remains the most costly and serious complication in replacement therapy of hemophilia A. We investigated the clinical significance of CD4(+)CD25(high) T regulatory (Treg) cells in hemophilia patients. Our trial included 6 severe hemophilia A patients with factor VIII inhibitors, 6 hemophilia patients without inhibition of factor VIII, and 6 hea...

Lymphoma is one of the most common malignant tumors in canine. Protein phosphatase 2A (PP2A), a well-conserved serine/threonine phosphatase, plays a critical role as a tumor suppressor. Perphenazine (PPZ) is one of the phenothiazines and widely used as an antipsychotic drug. Recently, it is reported that PPZ directly binds with scaffolding subunit of PP2A complex and exerts anti-tumor effects o...

Apoptosis of peripheral blood T cells has been suggested to play an important role in the pathogenesis of human immunodeficiency virus (HIV) infection. Spontaneous, Fas (CD95)-induced and activation-induced T cell apoptosis have all been described in peripheral blood mononuclear cell cultures of HIV-infected individuals. We have previously shown that activation-induced T cell apoptosis is Fas i...

Apoptosis of peripheral blood T cells plays an important role in the pathogenesis of human immunodeficiency virus (HIV) infection. In this study, we found that HIV type 1 (HIV-1) primes CD4(+) T cells from healthy donors for apoptosis, which occurs after CD95 ligation or CD3-T-cell receptor (TCR) stimulation. CD95-mediated death did not depend on CD4 T-cell infection, since it occurred in the p...

The aims of this study were to elucidate the immunomodulatory effects of glycyrrhizin (GL) on CD4(+)T cell responses during liver fibrogenesis. To obtain in vivo evidence about the effects of GL on CD4(+)T cells in livers and spleens of concanavalin A (ConA)-induced mouse model, mice were administrated with ConA together with or without GL for 8 weeks. Mice treated with GL dramatically prevente...

Adult T-cell acute lymphoblastic leukemia (T-ALL) has a poor prognosis. Although it has been found that activation of Notch1 signaling occurs in >50% T-ALL patients, γ-secretase inhibitors that target Notch1 signaling are of limited efficacy. However, c-Myc is an important direct target of Notch1 and, thus, c-Myc is another potential therapeutic target for T-ALL. Valproic acid (VPA), a histone ...

Bromodomain-containing protein 4 (BRD4) is an intracellular that regulates expression of various cellular functions. This study investigated whether BRD4 inhibition can alter the immunomodulatory and antitumor effects radiation therapy (RT). A murine breast cancer cell line was implanted into BALB/c mice. The dual-tumor model used to evaluate abscopal RT. total 24 Gy delivered inhibitor injecte...
