Transcription factor forkhead box protein 3 (Foxp3) specifically characterizes the thymically derived naturally occurring regulatory T cells (Tregs). Limited evidence indicates that it is also expressed, albeit to a lesser extent, in tissues other than thymus and spleen, while, very recently, it was shown that Foxp3 is expressed by pancreatic carcinoma.(More)
BACKGROUND The expression of indoleamine 2,3-dioxygenase (IDO) by tumor cells has been considered as a major tumor immune escape mechanism. The aim of this study was to investigate the expression of IDO in lung cancer cell lines as well as in surgically resected lung cancer specimens comparing the latter, to the expression in autologous samples from the(More)
Amongst the numerous mediators contributing towards the escape of tumors from the host's immune response against them, the enzyme indoleamine 2,3-dioxygenase (IDO) has recently attracted special attention. By catabolizing tryptophan to N-formyl-kynurenine, IDO starves T cells from this important amino acid rendering them incapable of mounting appropriate(More)
Boosting pre-existing, naturally occurring cytolytic CD8(+) T-cell (CTLs) responses directed against class-I MHC-restricted peptides of tumor antigens, represents a primary goal of cancer immunotherapy. The number of pre-existing antitumor CTLs and their impaired function has been incriminated as the most likely candidates for the reduced clinical efficacy(More)
OBJECTIVES Our aim is to report four novel α-gal A gene (GLA) mutations resulting in Fabry disease (FD) and provide evidence of pathogenicity of the D313Y mutation regarding which contradictory data have been presented in the literature. SETTING AND PARTICIPANTS Twenty-five family members of nine unrelated patients with definite FD diagnosis, 10(More)
BACKGROUND This study aimed to examine whether EBV seropositive patients with lung cancer have an altered virus-specific CTL response, as compared to age-matched healthy controls and whether any variation in this response could be attributed to senescence. METHODS Peripheral blood mononuclear cells from lung cancer patients, age-matched and younger(More)
