Molecular pathogenesis of malignant lymphoma. The goal with this project is to increase our understanding of the molecular pathogenesis of malignant lymphoma in order to identify markers for aggressive and indolent disease and  find new potential therapeutic targets. Specifically we investigate the role of the SOXC transcription factors, the cannabinoid receptors andlipid mediators belonging to the endocannabinoid system.

The project aims to increase the knowledge on pathogenetic mechanisms in lymphoproliferative disorders and lymphoma. Special focus is on 1) the functional role of the cannabinoid receptors and their physiological agonists - arachidonic acid derivatives produced by cells in the lymphoma microenvironment. 2) how signaling from cells in the microenvironment and how the gut microbiome contribute to the pathogenesis. 3) the functional role of the SOXC transcription factors in lymphoma. 4) genetic alterations associated with tumor progression and relapse in mantle cell lymphoma. We have a well-characterized patient cohort with corresponding biobanked tumors including samples from indolent and aggressive disease and primary and relapse samples. NGS and other methods are used for characterizing genetic and epigenetic changes, analyse gene and protein expression. This project will lead to increased knowledge on mechanisms underlying lymphoma pathogenesis and may open up for more individualized therapy. It will lead to better understanding of disease progression and to find markers and mutations that can guide the choice of therapy already at the time of diagnosis. The cannabinoid receptors are also interesting potential therapeutic targets in lymphoproliferative disorders.
