Here we report that human nonsmall cell lung carcinomas overexpress macrophage migration inhibitory factor (MIF) and thioredoxin (Trx), 2 oxidoreductases with cytokine function, and contain more abundant nonprotein thiols (glutathione and cysteine) than nonneoplastic lung tissues. Cell clones derived from the same lung carcinoma cell lines but expressing(More)
Interaction of NK cells with autologous immature dendritic cells (iDCs) results in reciprocal activation. We have previously reported that NK cells trigger iDC to polarize and secrete IL-18; in turn, DC-activated NK cells secrete the nuclear protein/proinflammatory cytokine high mobility group box protein 1 (HMGB1), which induces DC maturation and prevents(More)
The mechanisms by which adenomatous polyposis coli (APC) gene mutations contribute to colorectal tumourigenesis and progression are still not fully understood. Using in vitro mouse embryonic stem cells, APC mutations have been proposed to dysregulate the interactions between kinetochores and microtubules during mitosis, leading to chromosomal instability(More)
Whether in vivo specific gene mutations lead to chromosomal instability (CIN) and aneuploidy or viceversa is so far not proven. We hypothesized that aneuploidy among human sporadic colorectal adenomas and KRAS2 and APC mutations were not independent. Additionally, we investigated if 1p34–36 deletions by dual target FISH were associated with aneuploidy.(More)
Marginal zone (MZ) B cells, identified as surface (s)IgM(high)sIgD(low)CD23(low/-)CD21(+)CD38(-) B cells, were purified from human spleens, and the features of their V(D)J gene rearrangements were investigated and compared with those of germinal center (GC), follicular mantle (FM) and switched memory (SM) B cells. Most MZ B cells were CD27(+) and exhibited(More)
