Cui et al. (2021/China) performed an in-vitro study on the Homosapien bone marrow neuroblastoma (SH-SY5Y) cell line to assess the absorption rate of VB12, an inhibitor of LRRK2 activity, as VB12-loaded tetrahedral framework nucleic acid (TVC) by flow cytometry. Here, LRRK2 is linked to neuroblastoma.
