BIO-LGCA: A cellular automaton modelling class for analysing collective cell migration.

PLoS Comput Biol 2021 Jun 15;17(6):e1009066. Epub 2021 Jun 15.

Centre for Information Services and High Performance Computing, Technische Universität Dresden, Dresden, Germany.

Collective dynamics in multicellular systems such as biological organs and tissues plays a key role in biological development, regeneration, and pathological conditions. Collective tissue dynamics-understood as population behaviour arising from the interplay of the constituting discrete cells-can be studied with on- and off-lattice agent-based models. However, classical on-lattice agent-based models, also known as cellular automata, fail to replicate key aspects of collective migration, which is a central instance of collective behaviour in multicellular systems.

ENT2 facilitates brain endothelial cell penetration and blood-brain barrier transport by a tumor-targeting anti-DNA autoantibody.

JCI Insight 2021 Jun 15. Epub 2021 Jun 15.

Department of Therapeutic Radiology, Yale School of Medicine, New Haven, United States of America.

The blood-brain barrier (BBB) prevents antibodies from penetrating the CNS and limits conventional antibody-based approaches to brain tumors. We now show that ENT2, a transporter that regulates nucleoside flux at the BBB, may offer an unexpected path to circumventing this barrier to allow targeting of brain tumors with an anti-DNA autoantibody. Deoxymab-1 (DX1) is a DNA-damaging autoantibody that localizes to tumors and is synthetically lethal to cancer cells with defects in the DNA damage response. Read More
