Tarantelli, Chiara Argnani, Lisa Zinzani, Pier Luigi Bertoni, Francesco 2021 The development of small molecules able to block specific or multiple isoforms of phosphoinositide 3-kinases (PI3K) has already been an active field of research for many years in the cancer field. PI3Kδ inhibitors are among the targeted agents most extensively studied for the treatment of lymphoma patients and PI3Kδ inhibitors are already approved by regulatory agencies. More recently, it became clear that the anti-tumor activity of PI3K inhibitors might not be due only to a direct effect on the cancer cells but it can also be mediated via inhibition of the kinases in non-neoplastic cells present in the tumor microenvironment. T-cells represent an important component of the tumor microenvironment and they comprise different subpopulations that can have both anti- and pro-tumor effects. In this review article, we discuss the effects that PI3Kδinhibitors exert on the immune system with a particular focus on the T-cell compartment. application/pdf https://localhost:5000/ark:/12658/srd1322802 https://susi.usi.ch/global/documents/322802 https://susi.usi.ch/documents/322802/files/Bertoni_2021_MDPI_cancers.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.3390/cancers13215535 info:eu-repo/semantics/altIdentifier/ark/12658/srd1322802 info:eu-repo/semantics/openAccess CC BY Cancers. - 2021, vol. 13, p. 5535.
