Brain cells in people with Alzheimer's disease (AD) show failing mitochondria, the cell's energy-producing structures, early in the disease. This failure seems to help drive the illness, but the cause is not well understood.

What they work on

  1. Test whether removing PDE2A, an enzyme that breaks down the messengers cAMP and cGMP, from the forebrain protects against pathology and memory deficits, by crossing conditional knockout mice with Alzheimer's transgenic mouse models.
  2. Determine how PDE2A2, the form of PDE2A located in mitochondria, affects brain function and behavior in Alzheimer's disease mouse models.
  3. Explore how excess PDE2A disrupts mitochondrial dynamics, such as fragmentation, and the expression and assembly of electron transport chain complexes that power energy production in neurons.

More about the research

One candidate is PDE2A, an enzyme that breaks down cAMP and cGMP. These are small messenger molecules that help control many cell functions, including mitochondrial shape and energy production. PDE2A is especially abundant in the hippocampus and the frontal and temporal cortex, brain regions hit hard by AD.

Why it matters

Alzheimer's disease has few effective treatments. If faulty PDE2A signaling drives the mitochondrial damage seen in the disease, drugs that block PDE2A, especially its mitochondrial form PDE2A2, could become a new treatment approach. Such drugs could target energy failure in the brains of patients with Alzheimer's disease.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
