Toxicologists are integral in the multidisciplinary team managing GVHD. They provide expertise in understanding the adverse effects of conditioning regimens and immunosuppressive therapies. Toxicologists also aid in the development of strategies to mitigate these effects and improve patient outcomes. Furthermore, they are involved in research aimed at identifying biomarkers for early detection and monitoring of GVHD, as well as in the development of novel therapeutics with improved safety profiles.
