CD49d promotes disease progression in chronic lymphocytic leukemia : new insights from CD49d bimodal expression

Tissino, Erika ; Pozzo, Federico ; Benedetti, Dania ; Caldana, Chiara ; Bittolo, Tamara ; Rossi, Francesca Maria ; Bomben, Riccardo ; Nanni, Paola ; Chivilò, Hillarj ; Cattarossi, Ilaria ; Zaina, Eva ; Norris, Kevin ; Polesel, Jerry ; Gentile, Massimo ; Tripepi, Giovanni ; Moia, Riccardo ; Santinelli, Enrico ; Innocenti, Idanna ; Olivieri, Jacopo ; D’Arena, Giovanni ; Laurenti, Luca ; Zaja, Francesco ; Pozzato, Gabriele ; Chiarenza, Annalisa ; Di Raimondo, Francesco ; Rossi, Davide ; Pepper, Chris ; Hartmann, Tanja Nicole ; Gaidano, Gianluca ; Del Poeta, Giovanni ; Gattei, Valter ; Zucchetto, Antonella

CD49d is a remarkable prognostic biomarker of chronic lymphocytic leukemia (CLL). The cutoff value for the extensively validated 30% of positive CLL cells is able to separate CLL patients into 2 subgroups with different prognoses, but it does not consider the pattern of CD49d expression. In the present study, we analyzed a cohort of 1630 CLL samples and identified the presence of ∼20% of CLL...

The role of TNFR2 and DR3 in the in vivo expansion of tregs in T cell depleting transplantation regimens

Rodriguez-Barbosa, Jose-Ignacio ; Schneider, Pascal ; Graca, Luis ; Bühler, Leo ; Perez-Simon, Jose-Antonio ; Rio, Maria-Luisa del

In: International Journal of Molecular Sciences, 2020, vol. 21, no. 9, p. 3347

Regulatory T cells (Tregs) are essential for the maintenance of tolerance to self and non-self through cell-intrinsic and cell-extrinsic mechanisms. Peripheral Tregs survival and clonal expansion largely depend on IL-2 and access to co-stimulatory signals such as CD28. Engagement of tumor necrosis factor receptor (TNFR) superfamily members, in particular TNFR2 and DR3, contribute to promote...

Detection of HER2+ breast cancer cells using bioinspired DNA-based signal amplification

Rafiee, Sarah D. ; Kocabey, Samet ; Mayer, Michael ; List, Jonathan ; Rüegg, Curzio

In: ChemMedChem, 2020, vol. 15, no. 8, p. 661-666

Circulating tumor cells (CTC) are promising biomarkers for metastatic cancer detection and monitoring progression. However, detection of CTCs remains challenging due to their low frequency and heterogeneity. Herein, we report a bioinspired approach to detect individual cancer cells, based on a signal amplification cascade using a programmable DNA hybridization chain reaction (HCR) circuit. We...

Epithelial-mesenchymal transition in cancer metastasis through the lymphatic syste

Karlsson, Mikael C. ; Gonzalez, Santiago F. ; Welin, Josefin ; Fuxe, Jonas

In: Molecular oncology, 2017, vol. 11, p. 781–791

It was already in the 18th century when the French surgeon LeDran first noted that breast cancer patients with spread of tumor cells to their axillary lymph nodes had a drastically worse prognosis than patients without spread (LeDran et al., ). Since then, metastatic spread of cancer cells to regional lymph nodes has been established as the most important prognostic factor in many types of...

Breast cancer stem cells with tumor- versus metastasis-initiating capacities are modulated by TGFBR1 inhibition

Fico, Flavia ; Bousquenaud, Mélanie ; Rüegg, Curzio ; Santamaria-Martínez, Albert

In: Stem Cell Reports, 2019, vol. 13, no. 1, p. 1–9

Cancer stem cells (CSCs) are defined by their ability to regenerate a tumor upon transplantation. However, it is not yet clear whether tumors contain a single CSC population or different subsets of cells with mixed capacities for initiating primary and secondary tumors. Using two different identification strategies, we studied the overlap between metastatic stem cells and tumor-initiating...

LPS nephropathy in mice is ameliorated by IL-2 independently of regulatory T cells activity

Bertelli, Roberta ; Di Donato, Armando ; Cioni, Michela ; Grassi, Fabio ; Ikehata, Masami ; Bonanni, Alice ; Rastaldi, Maria Pia ; Ghiggeri, Gian Marco

In: Plos one, 2014, vol. 9, no. 10, p. e111285

Immunosuppressive regulatory T cells (Tregs) have been hypothesized to exert a protective role in animal models of spontaneous (Buffalo/Mna) and/or drug induced (Adriamycin) nephrotic syndrome. In this study, we thought to define whether Tregs can modify the outcome of LPS nephropathy utilizing IL-2 as inducer of tissue and circulating Tregs. LPS (12 mg/Kg) was given as single shot in C57BL/6,...
