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.

Whitehead Institute Founding Member Rudolf Jaenisch and colleagues developed an approach to isolate and analyze phagosomes, which are an important organelle in microglia, a type of immune cell found in the brain. Microglia are involved in brain development, as well as neurodegeneration, brain cancer, and more so understanding their biology has many potential implications.

The Whitehead Institute together with the Department of Biology at the Massachusetts Institute
of Technology (Cambridge, Massachusetts) invites applications for a tenure-track appointment at
the Assistant Professor level.

Whitehead Institute Member David Page and colleagues measured the effects of the sex chromosomes on two types of immune cells, gaining insights into the cell-type-specific effects of gene regulation by sex chromosome genes. Their work also explores the biological underpinnings of sex biases in immunity and autoimmune disease.

Whitehead Institute graduate student researchers Christopher Giuliano and Julian Roessler have been awarded the 2024 Regeneron Prize for Creative Innovation. In addition, postdoctoral researcher Chen Weng was selected as a finalist in the postdoctoral fellows competition.

Whitehead Institute Member Mary Gehring has been selected as an Investigator of the Howard Hughes Medical Institute (HHMI), one of just 26 scientists appointed in 2024.

Whitehead Institute Member Siniša Hrvatin is studying tardigrades to decode the mechanisms enabling their survival in extreme environmental conditions. Learn about the biology of these microscopic “water bears” and what makes them a particularly fascinating model organism. Click here to view the full multimedia story.

Sonia Boor is a postdoc in Whitehead Institute Member Mary Gehring’s lab studying how to make the crop plant pigeon pea more resilient against climate change. We sat down with Sonia to learn more about her and her experiences in and out of the lab.
