Regulation and function of a hemicleaved Activin-A processing intermediate in melanoma

Activin-A is a Transforming Growth Factor-B (TGFB)-related cytokine that regulates various biological processes including cell proliferation and differentiation through autocrine, paracrine or endocrine signaling. Activin-A expression is upregulated in mul ...

Apelin-driven endothelial cell migration sustains intestinal progenitor cells and tumor growth

Mauro Delorenzi, Stefanie Siegert, Pascale Anderle Pedone, Nadine Fournier, Sina Nassiri, François Renevey, Michele De Palma, Mario Leonardo Squadrito, Simone Ragusa

Stem and progenitor cells residing in the intestinal crypts drive the majority of colorectal cancers (CRCs), yet vascular contribution to this niche remains largely unexplored. Vascular endothelial growth factor A (VEGFA) is a key driver of physiological a ...

The role of eosinophils in breast cancer

Luisa Spisak

Eosinophils are granulocytes and belong to the innate arm of immunity. Eosinophils can be in different basal or activation states and depending on which type of activation is applied, they exert different effector functions. These multi-functional cells ha ...

Engineering T Cell Trafficking and Function for Enhanced Cancer Immunotherapy

Yuqing Xie

In the past decades, breakthroughs in cancer immunotherapy have led to unprecedented clinical responses in patients with advanced-stage cancers that would otherwise be fatal. However, treatment of many solid organ malignancies with highly immunosuppressive ...

BCG hydrogel promotes CTSS-mediated antigen processing and presentation, thereby suppressing metastasis and prolonging survival in melanoma

Li Tang, Bing Feng, Thomas Gruber

Background The use of intralesional Mycobacterium bovis BCG (intralesional live BCG) for the treatment of metastatic melanoma resulted in regression of directly injected, and occasionally of distal lesions. However, intralesional-BCG is less effective in p ...

Cancer cell autophagy, reprogrammed macrophages, and remodeled vasculature in glioblastoma triggers tumor immunity

Julie Laetitia Scotton, Douglas Hanahan, Ksenya Shchors, Krisztian Homicsko, Mélanie Louise Tichet, Agnieszka Alicja Chryplewicz

Glioblastoma (GBM) is poorly responsive to therapy and invariably lethal. One conceivable strategy to circumvent this intractability is to co-target distinctive mechanistic components of the disease, aiming to concomitantly disrupt multiple capabilities re ...

Immunosuppressive roles of Activin-A in melanoma and characterization of its precursor cleavage

Katarina Pinjusic

Activin-A, a transforming growth factor ê µ family member, is a pleiotropic cytokine with diverse functions in development, fertility, adult tissue homeostasis, and aging. Accordingly, deregulation of Activin-A signaling has been associated with many patho ...

New approaches to uncover the minimally functional hematopoietic niche using the adipocytic differentiation axis: pharmacological modulation and adrenal niche induction

Frédérica Schyrr

Hematopoietic Stem and Progenitor Cells (HSPCs) reside in their niche, a structure that regulates the balance of cellular quiescence, self-renewal and commitment towards differentiated cells. This highly plastic niche is formed by several cellular players, ...

Dendritic cell cross-dressing and tumor immunity

Michele De Palma, Amaia Martinez Usatorre

In addition to direct and cross-presentation, dendritic cells (DCs) can present tumor antigens (TAs) to T cells via a hitherto poorly understood mechanism called "cross-dressing." DC cross-dressing involves the acquisition of preformed peptide-major histoc ...

Aberrant hyperexpression of the RNA binding protein FMRP in tumors mediates immune evasion

Nadine Fournier, Douglas Hanahan, Krisztian Homicsko, Mohammad Sadegh Saghafinia, Dalya Ataca, Qiqun Zeng, Mélanie Louise Tichet, Yuqing Xie, Agnieszka Alicja Chryplewicz, Fleuriane Marie Tryskele Laurene Gallean, Jeremy Gilles Louis Guillot, Simge Yücel, Lucine Christe, Peng Zhang, Inti Zlobec

Many human cancers manifest the capability to circumvent attack by the adaptive immune system. In this work, we identified a component of immune evasion that involves frequent up-regulation of fragile X mental retardation protein (FMRP) in solid tumors. FM ...
