This makes me truly excited: Going back to where my academic/scientific journey began. Only 3sthing years ago I was just starting to learn what making science was about, and my teachers and mentors at UNAM made it so easy to fall in love with it. #AlmaMater #SalamanderMetting2026

What are the mechanisms allowing #zebrafish to #regenerate their neurons after spinal cord injury? This study by @albertodseara.bsky.social , Catherine Becker, Thomas Becker &co shows that a protein in #microglia regulates regenerative #neurogenesis in multiple ways 🧪#AcademicSky plos.io/4xy2CcB
A graphical summary of proposed interactions of sema4ab during spinal cord regeneration. After spinal injury, microglia likely control neurogenesis directly by signaling through Sema4ab and Plxnb1a/b on ependymo-radial glial cells (ERGs), and indirectly by changing the injury site environment, which leads to lower expression of tgfb3, a positive regulator of regenerative neurogenesis, in fibroblasts. Additionally, Sema4ab controls microglia number by promoting cell proliferation.

New preprint from our lab! Rita Aires et al., looked into how tissue remodelling is regulated during limb regeneration. In short, depending on what tissues are injured, a tailored response ensures the right immune cells are recruited to ensure skeletal integration. www.biorxiv.org/content/10.6...

Tissue-resident macrophages are doing more than just protecting from infection. In this interesting paper, René Fernando Abarca-Buis et al shows that they can promote reepithelialization and blastema formation and regulate the maturation of chondrocytes. Check it out here: doi.org/10.1016/j.cd...
