Breaking New Cell Biology Research
TANK-binding kinase 1 (TBK1) participates in many important cellular processes innate immunity, metabolism and organelle quality control. This study identifies new functions for TBK1 at lysosomes where it is important for the ability of cells to properly respond to changes in amino acid availability. This study shows that TBK1 undergoes dynamic recruitment to lysosomes when amino acids are abundant and that this results in an activation of TBK1. It furthermore identifies Rab7 as an important target of TBK1 at lysosomes that is critical for the ability of TBK1 to activate the mechanistic target of rapamcyin complex 1 (mTORC1), a major regulator of anabolic processes. Interestingly, a TBK1 mutant that causes neurodegenerative diseases (amyotrophic lateral sclerosis and frontotemporal dementia) is constitutive active at lysosomes.

Super-resolution microscopy reveals the local distribution of proteins inside cells at the nanoscale but is in practice limited to visualizing only 2 to 3 different proteins in the same cell. FLASH-PAINT breaks this limit and empowers cell biologists to interrogate the complex spatial relationships between an essentially unlimited number of different molecules.

This research reveals a novel pathway that integrates multiple signals related to lysosome stress in order to activate leucine rich repeat kinase 2 (LRRK2). Mutations that increase LRRK2 kinase activity are major contributors to Parkinson’s disease risk. Therefore, the lysosome perturbations that were defined in this study may increase Parkinson's disease risk by raising LRRK2 kinase activity. In other words, this research suggests that an exaggerated response to lysosome quality control may contribute Parkinson's disease risk.

The ISAC award provides seed funding for exceptionally innovative, disruptive (high-risk/high-reward) research relevant to the NIDDK Division of Kidney, Urologic, & Hematologic Diseases that has the potential to lead to groundbreaking or paradigm-shifting results that will change the field. The von Blume lab investigates how neutrophils, frontline defenders against infections, are armed with proteins in distinct granule types. Regulated exocytosis activates them for chemotaxis, phagocytosis, and bacteria eradication. Yet, the molecular mechanisms of granule formation are unclear, limiting treatments for neutropenic disorders. The von Blume lab will investigate molecular mechanisms of neutrophil granule biogenesis that could pave the way for powerful therapeutic strategies. This project will be performed in collaboration with Shangqin Guo’s Yale Stem Cell Center lab.
