Rewiring an olfactory circuit by altering cell-surface combinatorial code - Nature In Drosophila, changing the expression of a small set of cell-surface proteins in just one type of olfactory neuron rewires its connections almost entirely to a new postsynaptic partner neuron type, altering the fly’s odour response and courtship behaviour.

Novel environment exposure drives temporally defined and region-specific chromatin accessibility and gene expression changes in the hippocampus - Nature Communications Hippocampal neurons adapt to experience through changes in gene expression and chromatin accessibility. Here, authors show that novel environment exposure induces region- and cell-type specific transc...

Extremely excited to share the outcome of a fantastic collaboration with @erinduffyphd.bsky.social revealing how experiences reshape hippocamapl chromatin and gene expression.

Cell atlas of the endometrium in women with PCOS may lead to better treatment Women with polycystic ovary syndrome (PCOS) find it harder to get pregnant, have more frequent miscarriages and have a higher risk of developing endometrial cancer. Now, in a new study published in Na...

A new study in @natmedicine.bsky.social by KI professor @elisabetsv.bsky.social and colleagues shows that the endometrium of women with #PCOS differs in terms of both the composition of individual cells and gene expression. The results open the door to new treatments 🧪 news.ki.se/cell-atlas-o...

Rewiring an olfactory circuit by altering the combinatorial code of cell-surface proteins Proper brain function requires the precise assembly of neural circuits during development. Despite the identification of many cell-surface proteins (CSPs) that help guide axons to their targets, it re...

In drosophila, by manipulating sets of surface proteins, you can re-engineer connectivity of olfactory neurons and generate a new neuron type that alters courtship behavior. Impressive work from the Luo lab.
