KRAB zinc finger proteins link heterochromatin maintenance to replicative stress and inflammation in diffuse large B-cell lymphoma

Filipe Amândio Brandão Sanches Vong Martins

Genomic instability enhances cancer progression by favoring clonal diversity, yet uncontrolled replicative stress can lead to mitotic catastrophe and inflammatory responses promoting immune rejection. KRAB-containing zinc finger proteins (KZFPs) are epigen ...

Optimized Modeling of Metastatic Triple-Negative Invasive Lobular Breast Carcinoma

Cathrin Brisken, Laura Battista, Georgios Sflomos

Simple Summary Invasive lobular carcinoma (ILC) is the second most common histologic subtype of breast cancer and is often detected at an advanced stage. Up to 30% of ILC cases relapse and present a challenge for treatment. Unfortunately, there are few mod ...

Exploring the interplay of molecular pattern and valency for selective interactions at the bio-interface

Kaltrina Paloja

Cell-cell communication is fundamental for immune balance. Multivalent interactions of surface receptors at immune interfaces drive specific communication, with stimulatory and inhibitory signals guiding the immune outcome. Notably, the valency, affinity, ...

CellCharter reveals spatial cell niches associated with tissue remodeling and cell plasticity

Albert Santamaria Martinez, Giovanni Ciriello, Daniele Tavernari

Tissues are organized in cellular niches, the composition and interactions of which can be investigated using spatial omics technologies. However, systematic analyses of tissue composition are challenged by the scale and diversity of the data. Here we pres ...

Optimised three-dimensional in vitro retinoblastoma models tailored for drug discovery and clinical translatability

Irina Sinenko

Retinoblastoma, while relatively rare, stands as the most prevalent intraocular cancer. In Switzerland, the survival rate approaches 100%, but it drops to less than 50% in low-income countries. The current treatment options for retinoblastoma rely on a lim ...

Soft cancer cells squeeze through T cell's grip

Armand Kurum, Li Tang, Yi Wang

Immune cells are exquisitely sensitive to the mechanical properties of cancer cells. Soft cancer cells can avoid immune-mediated destruction. Therapeutically targeting this mechanical immune checkpoint may enhance the efficacy of cancer immunotherapy. ...

Colon tumour cell death causes mTOR dependence by paracrine P2X4 stimulation

Andrea Ablasser

Solid cancers exhibit a dynamic balance between cell death and proliferation ensuring continuous tumour maintenance and growth(1,2). Increasing evidence links enhanced cancer cell apoptosis to paracrine activation of cells in the tumour microenvironment in ...

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 ...

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 ...
