Thrilled to share that our "Poster at a Glance" on #Phagocytosis is out! Thank you @jcellsci.bsky.social @biologists.bsky.social for the invitation ! Prepared with @manondepierre.bsky.social @chiarapompili.bsky.social from @institutcochin.bsky.social journals.biologists.com/jcs/article/...
Phagocytosis at a glance
Summary: Phagocytosis involves receptor-driven actin and membrane remodelling to engulf microbes and debris. The phagosome then matures for degradation, supporting both nutrition and immune responses.
