Why do you think lipids are now emerging as a central player in neuro-oncology, particularly in understanding how gliomas communicate with the brain?
They shape membranes, signaling, organoid function, inflammation, and cell identity.
In the brain, this is especially important because the brain is one of the most lipid-rich organs, and neurons, glial cells, and tumor cells are constantly exchanging lipid-related signals and metabolites.
Our work suggests that lipid dysfunction is not simply a consequence of glioma growth.
It can actively influence tumor evolution by damaging mitochondria and the nucleus envelope, increasing oxidative stress and promoting chromosomal instability.
At the same time, altered lipid metabolism changes how microglia and macrophages respond to the tumor.
Therefore, lipids may provide a common language through which glioma cells communicate with the surrounding brain, affecting both cancer cell evolution and immune microenvironment.
One theme throughout your work is that lipid droplets are not simply a marker of dysfunctional cells.
How has understanding of lipid-laden microglia evolved and what lessons from neurodegeneration might apply to glioma?
Lipid droplets were once viewed mainly as passive storage structures or nonspecific markers of agent and cellular stress.
We now understand that they can reflect a much deeper disruption of lipid trafficking.
This suggests that lipid-laden microglia are not simply overloaded cells, they have undergone a functional state change.
The lesson for glioma is that lipid-rich tumor-associated microglia and macrophages cannot all be equivalent.
Some may still retain protective functions, whereas others may be metabolically trapped in an immune-suppressive state.
Understanding how and when that transition occurs may be more useful than simply identifying cells that contain lipid droplets.
