During injury, macrophages are the swiss knife: they do it all! Clean up, repair, protect.... But how is each step molecularly regulated? Our talented postdoctoral fellow Nicolas Denans tackled this problem by using scRNA-Seq, transgenic reporter lines and live imaging. He discovered that macrophages are activated sequentially and independently not by one but by 3 anti-inflammatory states!
Take a look: Nicolas is on the job market and has a wealth of data for future projects!

Zebrafish Genes Offer Clues to Healing Hearing Loss
Published in Technology Networks, scientists have discovered how two genes control the regeneration of sensory hair cells in zebrafish, offering new clues for addressing hearing loss in humans. Published in Nature Communications, the study, led by Tatjana Piotrowski, PhD, provides a clearer picture of how stem cells and their progeny divide to replenish damaged tissue – a process that fish perform naturally but humans cannot. These findings could open new avenues for regenerative medicine research targeting hearing and balance disorders.
