Bats rarely get sick from deadly viruses like Ebola and Nipah despite carrying them. Now, Whitehead Institute Founding Member Rudolf Jaenisch and colleagues have found that while the SARS-CoV-2 virus can enter bat cells, the innate immune system prevents it from replicating and hijacking the cell's machinery.

Whitehead Institute Member Rudolf Jaenisch and colleagues found that Rett Syndrome can cause significant mitochondrial dysfunction in astrocytes, a brain cell type that supports neurons, and in neurons that later acquire these mitochondria.

In Parkinson’s disease, clumps of sticky proteins trigger inflammation in the brain, leading to neuronal death. Whitehead Institute’s Founding Member Rudolf Jaenisch and colleagues have now found that a mutation causing these proteins to misfold and become sticky can also turn the brain’s immune cells from friends to foes, possibly accelerating the progression of the disease.
