An article published in the journal Cancer Research describes a new molecular mechanism that counteracts the immunosuppressive action of macrophages in promoting tumour growth, and provides knowledge of potential interest for designing future therapeutic options against cancer. The new preclinical study, in which researchers from the Sant Pau Research Institute (IIB Sant Pau) have participated, is led by Professor Annabel Valledor, from the Faculty of Biology (UB) and the Institute of Biomedicine of the UB (IBUB).
