Aberrant p15, p16, p53, and DAPK Gene Methylation in Myelomagenesis: Clinical a...
Geraldes, C; Gonçalves, AC; Cortesão, E; Pereira, MI; Roque, A; Paiva, A; Ribeiro, L; Nascimento-Costa, JM; Sarmento-Ribeiro, ABBACKGROUND: Aberrant DNA methylation is considered a crucial mechanism in the pathogenesis of monoclonal gammopathies. We aimed to investigate the contribution of hypermethylation of 4 tumor suppressor genes to the multistep process of myelomagenesis. METHODS: The methylation status of p15, p16, p53, and DAPK genes was evaluated in bone marrow samples from 94 patients at diagnosis: monoclonal gammopathy of unce...
Dendritic cells in cord blood transplantation: a review
Pereira, MI; Paiva, ADendritic cells (DCs) are a heterogeneous population of antigen-presenting cells derived from hematopoietic progenitors that bridge the transition between the innate and adaptive immune responses, while maintaining self-tolerance and Th1/Th2 homeostasis, by priming other cells in either an immunogenic or tolerogenic direction. Through their role in both innate and adaptive immunity, DCs play a major part in tra...
