Abstract

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is nowadays envisaged as a natural cytokine useful in nanomedicine to eradicate the cancer cells and not the healthy surrounding ones. However, it suffers from cell resistance and strong dispersion in body to prove its efficiency. The understanding at the molecular level of the TRAIL interaction with death receptors (DRs) on cancer cells is thus of fundamental importance to improve its action. We demonstrate here via molecular simulations that TRAIL can bind to its both agonistic DRs (ie, DR4 and DR5) with a preference for DR4. In this study, the role of a graphene nanoflake as a potential cargo for TRAIL is examined. Furthermore, both TRAIL self-assembling and TRAIL affinity when adsorbed on graphene are considered to enhance efficacy toward the targeted cancer cell. Our modelization results show that TRAIL can bind to DR4 and DR5 when transported by graphene nanoflake, as a proof of concept.
