For obvious reasons, I've become fascinated with retrotransposons. So we ( @alexwhiteley.bsky.social and I) wrote an article now out in Neuron @cellpress.bsky.social on how we think retrotransposons influence brain function and health! kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...

New preprint from my lab! We describe how transposable elements are activated in Parkinson’s disease, which is linked to an interferon response. We believe this study significantly advances our understanding of transposons and their role in human brains.

Activation of transposable elements is linked to a region- and cell-type-specific interferon response in Parkinson's disease
Parkinson's disease (PD) is a common age-related neurodegenerative disorder involving a neuroinflammatory response, the cause of which remains unclear. Transposable elements (TE) have been linked to i...

Why do some people with Alzheimer’s do not show symptoms of Alzheimer's?

During her PhD, @giorgitos.bsky.social explored this question. Part of the answer led her to an unexpected group of brain cells: underdeveloped neurons.

@labsalta.bsky.social identified persistent populations of immature neurons that were associated with ‘juvenile’ cellular functions, suggesting that these immature populations may actively contribute to maintaining homeostasis within the aged human hippocampus.

Our paper has sparked a lot of people asking me – so Keri, what’s the tldr – is there, or isn’t there, new neurons in the human hippocampus?

It's a little more complicated than a yes or no IMO.
Updated from the preprint, our paper, "Spatiotemporal analysis of gene expression in the human dentate gyrus reveals age-associated changes in cellular maturation and neuroinflammation" is now published.

Anyone working with single nuclei data should read this paper! (single cell too, but for nuclei data it's essential)

If I could only have one QC metric for single nuclei data, it would be spliced pct / intronic fraction (I think it's more useful even than number of UMIs 🤯).
