A transgenic inducible GFP extracellular-vesicle reporter (TIGER) mouse illuminates neonatal cortical astrocytes as a source of immunomodulatory extracellular vesicles.

ABSTRACT: Extracellular vesicles (EVs) are cellular derived particles found throughout the body in nearly all tissues and bodily fluids. EVs contain biological molecules including small RNAs and protein. EVs are proposed to be transferred between cells, notably, cells of the immune system. Tools that allow for in vivo EV labeling while retaining the ability to resolve cellular sources and timing of release are required for a full understanding of EV functions. Fluorescent EV fusion proteins are useful for the study of EV biogenesis, release, and identification of EV cellular recipients. Among the most plentiful and frequently identified EV proteins is CD9, a tetraspanin protein. A transgenic mouse containing a CRE-recombinase inducible CAG promoter driven CD9 protein fused to Turbo-GFP derived from
