Mice with acquired hypoparathyroidism would be useful for studying novel drug therapies for hypoparathyroidism. Two procedures to create such mice are demonstrated. The GFP-PTX mouse is generated by surgical parathyroidectomy guided by green fluorescing parathyroid glands. A second, non-surgical approach is based on parathyroid-specific expression of the diphtheria toxin receptor.

Stable intravital high-resolution imaging of immune cells in the liver is challenging. Here we provide a highly sensitive and reliable method to study migration and cell-cell-interactions of immune cells in mouse liver over long periods (about 6 hours) by intravital multiphoton laser scanning microscopy in combination with intensive care monitoring.

FAQs
Because GFP expression follows the endogenous Cx3cr1 regulatory region, fluorescence reports activity of that regulatory program rather than a separately introduced cell marker. This linkage lets investigators localize Cx3cr1-positive cells and examine their morphology in tissue. The signal therefore connects cellular visualization with questions about chemokine-receptor-associated immune populations in the nervous system.
No. Microglia are a major GFP-labeled population, but the model can also reveal other Cx3cr1-positive myeloid cells. Researchers should therefore interpret fluorescence as evidence of Cx3cr1-associated identity rather than an exclusive microglial label. This distinction matters when comparing cell distribution, migration, or interactions among immune populations in nervous-system tissue.
The genetic design can produce genotype-dependent effects on Cx3cr1 function, so the reporter may influence the biology being measured rather than serving as a completely neutral label. Experimental comparisons should account for genotype when evaluating microglial behavior, immune responses, or disease-related changes. Ignoring this factor can complicate interpretation of fluorescence and cellular outcomes.
Intravital imaging enables researchers to follow labeled cells in living tissue, making it useful for examining migration and changing interactions with neurons over time. Fixed-tissue fluorescence microscopy instead provides a preserved view of cell distribution and morphology. Using either approach, investigators can connect spatial organization with cellular behavior, while recognizing that each captures a different experimental context.
Researchers examine living or fixed nervous-system tissue with fluorescence microscopy and identify GFP-positive cells for further analysis. They can then assess where cells are located, how their morphology varies, whether they migrate, and how they interact with neurons. Intravital imaging extends this workflow by allowing those features to be tracked in living tissue.
These mice support studies of microglial development, neuroinflammation, responses to injury, and mechanisms of neurological disease. The reporter helps investigators relate immune-cell distribution and morphology to neuronal interactions, while live imaging can add information about migration. Such applications make the model useful for connecting cellular behavior with changing nervous-system conditions.
The model can provide visual information about the distribution and morphology of Cx3cr1-positive cells, as well as their migration and interactions with neurons. These observations help characterize how immune cells are organized in nervous tissue and how their behavior changes during development, inflammation, injury, or neurological disease research.
