Microglia reveal distinct disease patterns in genetic and sporadic frontotemporal dementia
A study from the University of Eastern Finland identifies common lysosomal dysfunction in both genetic and sporadic forms of frontotemporal dementia. Researchers found that microglial cells exhibit distinct gene expression patterns that may contribute to neuronal degeneration.
Why it matters

Add as preferred source Credit: CC0 Public Domain In frontotemporal dementia, degeneration of neurons in the frontal and temporal lobes of the brain leads to impairments in behavior, speech and movement. However, it has become evident that other brain cells can also be involved in disease processes that lead to neuronal degeneration. For example, the importance of microglial cells, which regulate inflammatory responses in the brain, has recently been emphasized in the disease processes of frontotemporal dementia.
