[HTML][HTML] Cancer-associated fibroblasts induce metalloprotease-independent cancer cell invasion of the basement membrane

…, F Zaccarini, M Lae, D Loew, F Dingli, P Sirven… - Nature …, 2017 - nature.com
At the stage of carcinoma in situ, the basement membrane (BM) segregates tumor cells from

pervasive across human cancers and comprise heterogeneous populations. The …

Selective STING stimulation in dendritic cells primes antitumor T cell responses

…, C Hoffmann, F Delisle, E Djacoto, P Sirven… - Science …, 2023 - science.org
T cells that recognize tumor antigens are crucial for mounting antitumor immune responses.
Induction of antitumor T cells in immunogenic tumors depends on STING, the intracellular …

Adjustment of dendritic cells to the breast-cancer microenvironment is subset specific

…, F Noël, E Zakine, U Czerwinska, P Sirven… - Nature …, 2018 - nature.com
The functions and transcriptional profiles of dendritic cells (DCs) result from the interplay
between ontogeny and tissue imprinting. How tumors shape human DCs is unknown. Here we …

Diversification of human plasmacytoid predendritic cells in response to a single stimulus

…, V Saint-André, J Di Domizio, P Vargas, P Sirven… - Nature …, 2018 - nature.com
Innate immune cells adjust to microbial and inflammatory stimuli through a process termed
environmental plasticity, which links a given individual stimulus to a unique activated state. …

[PDF][PDF] Dissecting effects of anti-cancer drugs and cancer-associated fibroblasts by on-chip reconstitution of immunocompetent tumor microenvironments

…, SS Evans, M Cossutta, Y Khira, W Han, P Sirven… - Cell reports, 2018 - cell.com
