Journal ArticleDOI
Lymphotoxin-β receptor in microenvironmental cells promotes the development of T-cell acute lymphoblastic leukaemia with cortical/mature immunophenotype
Mónica T. Fernandes,Marinella N. Ghezzo,André B. Silveira,Ravi Kiran Reddy Kalathur,Vanda Póvoa,Ana R. Ribeiro,Ana R. Ribeiro,Silvia Regina Brandalise,Emmanuel Dejardin,Nuno L. Alves,Nuno L. Alves,Jacques Ghysdael,Jacques Ghysdael,Jacques Ghysdael,João T. Barata,José Andrés Yunes,Nuno R. dos Santos +16 more
TL;DR: LT expression by T‐ALL cells activates LTβR signalling in thymic stromal cells, thus promoting leukaemogenesis, and inactivation of Ltbr results in a significant delay in TEL‐JAK2‐induced leukaemia onset.
Journal ArticleDOI
Reduced BAFF-R and increased TACI expression in common variable immunodeficiency.
Rita R. Barbosa,Susana L. Silva,Sara P. Silva,Alcinda Campos Melo,M. Conceição Pereira-Santos,João T. Barata,Lennart Hammarström,Marilia Cascalho,Ana E. Sousa +8 more
TL;DR: The results indicate that availability of BAFF determines BAFF-R and TACI expression on B cells, and that BAff-R expression is controlled by BAFF binding.
Journal ArticleDOI
Overexpression of wild-type IL-7Rα promotes T-cell acute lymphoblastic leukemia/lymphoma.

TL;DR: The work in this article was supported by the MRC under Programme Codes U117573801 and MR/P011225/1, to and by the consolidator grant ERC CoG-648455 from the European Research Council, under the European Union’s Horizon 2020 research and innovation programme, and the FAPESP/20015/2014 grant from Fundacao para a Ciencia e a Tecnologia (FCT) (J.T.B.).
Journal ArticleDOI
Stem Cell Leukemia: how a TALented actor can go awry on the hematopoietic stage.
TL;DR: Recent findings that shed light into the intricacies of TAL1 (epi)genetic regulation and the transcription network orchestrated by this major T-cell oncogene are emphasized.
Journal ArticleDOI
On CK2 regulation of chronic lymphocytic leukemia cell viability
Leila R. Martins,Paulo Sérgio Lucio,Milene Costa da Silva,Paula Gameiro,Maria Gomes da Silva,João T. Barata +5 more
TL;DR: It is shown that inhibition of CK2 induces apoptosis of CLL cells, whereas it does not significantly impact normal lymphocytes, demonstrating the selectivity of the CK2 inhibitors toward leukemia cells.
