Loss-of-function mutations and deletions in Wilms tumor 1 (WT1) gene are present in approximately 10% of T-cell acute lymphoblastic leukemia. Clinically, WT1 mutations are enriched in relapsed series and are associated to inferior relapse-free survival in thymic T-cell acute lymphoblastic leukemia cases. Here we demonstrate that WT1 plays a critical role in the response to DNA damage in T-cell ...

Adult T-cell leukemia/lymphoma is a lymphoproliferative disorder of mature T lymphocytes associated with infection with human T-cell lymphotrophic virus type I (HTLV-I). Adult T-cell leukemia/lymphoma is characterized by clinical and laboratory polymorphism that allows it to be classified into four distinct subgroups: smoldering, chronic, acute and lymphomatous types. We present here two cases ...

Few cases have been reported in the literature. So far; karyotypes are usually complex. 14q11 abnormalities: very frequent, either as an inv(14)(q11q32) or as a translocation t(14;14)(q11;q32); another reported change involving 14q11 is a translocation t(X;14)(q28;q11), similar to the translocation observed in ataxia-telangectasia, involving the Mature T-cell Prolymphocyte 1 (MTCP1) gene locate...

Leukemia antigen-targeting vaccination therapy is a naturally occurring demand & its establishment is now desired For the treatment of hematological malignancies, including leukemia, striking advances in chemotherapy, targeted therapy such as tyrosine kinase inhibitors, and hematopoietic stem cell transplantation (HSCT), have been made. However, unfortunately, a substantial proportion of patien...

Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...

Abstract CD4 T cell exhaustion is associated with relapse in B leukemia (B-ALL) patients. However, checkpoint blockade not effective treating B-ALL. Using a murine model of B-ALL, we demonstrate that induced cells had unique regulatory-cytotoxic phenotype (T rctx) preferential expression markers (PD1/TIM3) as well IL10 and c-Maf, which are immunosuppressive Tr1 cells. Leukemia acting APCs elici...
