Cognitively Healthy Ageing

Henne Holstege’s interest in healthy aging and cognitive decline was sparked by the remarkably healthy brain of Hendrikje van Andel-Schipper, who passed away at 115 years old. When she was 112, van Andel-Schipper called the University Medical Center in Groningen to let them know that she had agreed to donate her body to science after she’d died. Gert Holstege, Henne’s father, was responsible for bodies donated to science. He was intrigued by her call, and went to visit and examine van Andel-Schipper and found her (and her brain) to be in top shape. When she passed away a few years later, her brain was donated to science. It turned out to be comparable to that of a typical 60-year-old! What made her brain so uniquely resistant to the usual aging and disease processes that affect so many seniors? Henne Holstege just had to find out. She switched from studying breast cancer genetics to exploring the unique genetic features of people who grow extraordinarily old.

100-Plus Study

One of Henne Holstege’s most influential research projects centers on understanding the genetic and lifestyle factors that allow some individuals to live over 100 years with minimal cognitive decline. She has established one of the world’s largest cohorts of cognitively healthy centenarians, creating a powerful resource for studying the unique genetic traits and mechanisms that protect against neurodegeneration.

Holstege and her team are well on their way in their search for answers: “We’ve been able to show that centenarians are indeed genetically protected, and we’ve been able to pinpoint the genetic factors involved. Now, the next step is to understand the underlying mechanisms. That’s what I want to tackle in Leuven.”

New Opportunities in Leuven

Henne Holstege joined the VIB-KU Leuven Center for Neuroscience as a group leader in November 2024. She will maintain her ongoing cohort studies in the Netherlands, working 50% at UMC Amsterdam and 50% at the VIB-KU Leuven Center for Brain & Disease Research. Her aim in Leuven is to focus on advancing functional studies, pursuing large-scale omics data generation with the biomaterials from the centenarians, and performing downstream functional experiments, further leveraging the rich data source she has built over the years with the 100-Plus Study in Amsterdam.

Ongoing Projects

Healthy aging is the equivalent of escaping or delaying harmful or fatal aging-related diseases. To identify molecular features that underlie the escape of neurodegenerative diseases, we compare the multi-level data derived from the 100-plus Study cohort with similar data derived from the normal population or from Alzheimer’s disease cases. To achieve this, we collaborate intensely with many Alzheimer’s disease researchers.

Proteomics

Collaboration with Prof. Guus Smit (VU), Prof. Marcel Reinders (TU Delft): To identify proteins that associate with maintaining cognitive health in the centenarians we have performed mass spectrometry on 220 brain tissues-samples with and without AD across an age continuum from 50 – 110 years. Using state of the art statistical models, we identified proteins that change with age, but do not associate with AD, and proteins that specifically associate with AD, regardless of age. See also the projects of Andrea Ganz and Meng Zhang. 

Neuropathology

Collaboration with Dr. Jeroen Hoozemans, Prof. A. Rozemuller (VUmc). Brain tissues donated by the centenarians are thoroughly investigated for the abundance of well-known disease-associated pathologies and this is associated with the level of cognitive performance.

Immunology

Collaborating with Prof. Jacques van Dongen, Prof. Frank Staal, Prof. dr. Eline Slagboom and dr. ir Erik van den Akker at the LUMC we are investigating the differential immune system response in cognitively healthy centenarians relative to the normal population.

iPSC Cell Generation

Collaboration with Dr. Vivi Heine (VU/VUmc). We are generating induced pluripotent stem cells from centenarians (iPSCs), and we have derived several fibroblast cell lines from skin-biopsies taken during brain autopsies. These can be used for functional experiments to test the genetic constellation that encodes long-term brain health.

Blood-Based Biomarkers Project

In collaboration with Prof. dr. ir. Charlotte Teunissen we will measure plasma biomarkers in all participants from the 100-plus Study (i.e. centenarians, their children and their partners).
