The research group studies the influence of microenvironment, and particularly carcinoma-associated fibroblasts (CAFs) on tumorigenesis in highly desmoplastic tumours, mainly Pancreatic Adenocarcinoma and Metastatic Colorectal Carcinoma (mCRC).
What desmoplasia is? Desmoplasia is a histological feature characterised by an increase in the production of specific collagens, fibronectin, glycosaminoglycans, proteoglycans and other extracellular matrix components, and an increase in the number of mesenchymal cells, especially CAFs. CAFs are therefore a type of myofibroblasts characterised by their morphology, independently of their location, and by the expression of a-SMA, vimentin, PDGFRB and FAP (Fibroblast Activating Protein), among other markers. However, their expression pattern may vary markedly depending on their location. In other terms, the fibroblasts have been said to present topographic differentiation that is due to the initial separation of the mesoderm during embryogenesis. The quantity is associated with the prognosis in different types of tumours. However, recent results suggest that qualitative aspects are more important than quantitative ones, with special consequences on prognosis and response to treatment.
Moreover, the tumoral stroma is a potential therapeutic target since its elimination or short-circuiting would remove the protection these cells confer on tumour cells. To date, various experimental strategies have been reported, but none with any notable success. Interestingly, recent works in pancreatic cancer call into question the role of CAFs as protumorogenic instigator and some authors argue that they might be acting as a host defence to constraint the tumour growth. Our experience with colorectal tumours suggests that CAFs are heterogeneous cells, and despite having common biomarkers may differentially express other proteins that characterise distinct subpopulations with different characteristics and functions, some being protumorigenic and other tumour-suppressive, and the net balance between such subpopulations is crucial for prognosis and drug response.
Therefore, the main research interests of the group are:
- Discovery of stromal biomarkers for response prediction in pancreatic and colorectal adenocarcinomas.
- Targeting specific CAFs as therapeutic strategy in desmoplastic tumours.
