Chronic granulomatous disease associated with common variable immunodeficiency ...
Pacheco, C; Morais, A; Rolo, R; Ferreira, L; Nabiço, R; Cunha, JINTRODUCTION: Chronic granulomatous disease associated with common variable immunodeficiency (GD-CVID), although well documented, is rare. Granulomatous lesions can affect several organs and are histologically indistinguishable from sarcoidosis. CLINICAL CASES: Case 1: A 39-year-old male patient with CVID, asymptomatic although with thrombocytopenia and mediastinal-hilar adenopathies. GD-CVID was diagnosed by b...
Immunoglobulin genes implicated in glioma risk
Pandey, JP; Kaur, N; Costa, N; Amorim, J; Nabico, R; Linhares, P; Vaz, R; Viana-Pereira, M; Reis, RMBoth genetic and environmental factors are thought to be causal in gliomagenesis. Several genes have been implicated in glioma development, but the putative role of a major immunity-related gene complex member, immunoglobulin heavy chain γ (IGHG) has not been evaluated. Prior observations that IGHG-encoded γ marker (GM) allotypes exhibit differential sensitivity to an immunoevasion strategy of cytomegalovirus...

Impact of EGFR genetic variants on glioma risk and patient outcome
Costa, BM; Viana-Pereira, M; Fernandes, R; Costa, S; Linhares, P; Vaz, R; Pinheiro, C; Lima, J; Soares, P; Silva, A; Pardal, F; Amorim, J; Nabiço, RBACKGROUND: The epidermal growth factor receptor (EGFR) regulates important cellular processes and is frequently implicated in human tumors. Three EGFR polymorphisms have been described as having a transcriptional regulatory function: two single-nucleotide polymorphisms in the essential promoter region, -216G/T and -191C/A, and a polymorphic (CA)(n) microsatellite sequence in intron 1. We aimed to elucidate the...

Prognostic value of MGMT promoter methylation in glioblastoma patients treated ...
Costa, BM; Caeiro, C; Guimarães, I; Martinho, O; Jaraquemada, T; Augusto, I; Castro, l; Osório, L; Linhares, P; Honavar, M; Resende, M; Nabiço, RGlioblastoma (GBM) is the most common and aggressive primary brain tumor. The identification of novel molecular prognostic markers of GBM has recently been an area of great interest in neuro-oncology. The methylation status of the MGMT gene promoter is currently a promising molecular prognostic marker, but some controversial data have precluded its clinical use. We analyzed MGMT methylation by methylation-speci...
