SIMR-1 acts downstream of the piRNA pathway to promote siRNA amplification by the Mutator complex and localizes to perinuclear foci distinct from Mutator foci, P granules and Z granules.
OptoGranules reveal the function of G3BP1 as a stress granule scaffold and demonstrate that protracted stress granule assembly is sufficient to drive neurodegeneration and the evolution of ALS-FTD pathology.

Gene knock-out of the omega-1 ribonuclease of Schistosoma mansoni eggs resulted in immunologically impaired phenotype, showcasing the novel application of CRISPR/Cas9 genome editing and utility for functional genomics in schistosomes.
The scaffolding protein Oskar organizes two types of germ granules by phase transition within the same cell but with distinct morphologies, composition and biological functions.
The rapid killing of macrophages by Mycobacterium tuberculosis aggregates, and the subsequent proliferation of the bacteria inside the dead cell, leads to a cell death cascade and explains the coupling of necrosis and pathogen growth observed in active disease.

Insulin secreting cells harbor distinct subpopulations of insulin granules and loss of one or the other correlates strongly with secretory deficiencies characterizing type-1 or type-2 diabetes.
An in vivo drug screen of FDA-approved compounds in zebrafish identified host-directed therapies against mycobacterial infection, including the drug clemastine, which targets the P2RX7-inflammasome axis to enhance bacterial control.

Expanded repeat RNAs associated with human neurodegenerative diseases can become incorporated into transported granules in neurons, perturbing their function to cause neuritic branching defects.
