FOLH1 and neoplasm: In our own recent efforts, we have recently modeled and investigated non-linearities, multi-bolus injections as well as albumin binding [93], and developed a novel spatiotemporal model to examine how various physiological parameters affect the delivery of RPT, using 177Lu-labeled Prostate-specific membrane antigen (PSMA), taking into account the complex tumor microenvironment [55,94].
