🐦🧭 A team at the University of #Bonn found that #pigeons rely on iron-rich #macrophages in their livers to sense #Earth’s magnetic fields.

When researchers deactivated these #cells, the #birds lost their way on overcast days – but navigated fine under sunny skies, confirming a backup magnetic system that kicks in when visual cues aren’t available.

How pigeons exploit magnetic fields for navigation

Iron-rich immune cells in the liver may act as sensors for magnetic fields, serving as an internal compass.

"pigeons may sense magnetic field using iron-rich immune cells in their livers, a quantum effect... Findings suggest a new link between immunity and sensory perception in #birds... Many questions remain, particularly how signals from these cells are processed in the brain"

Intravital calcium imaging of meningeal macrophages reveals niche-specific dynamics and aberrant responses to brain hyperexcitability

Intravital microscopy of meningeal macrophage Ca²⁺ dynamics reveals previously unknown population heterogeneity, vasomotion-coupled activity, and diverse responses during steady state and neuroinflammatory conditions, offering relevant insights into brain immune regulation.

UCLA Researchers Identify and Clear Senescent Macrophages to Reverse Fatty Liver Disease in Mice

UCLA scientists have discovered a population of senescent “zombie” immune cells, specifically macrophages marked by p21 and TREM2 proteins, that accumulate in aging livers and drive chronic…

#Macrophages don’t just follow chemoattractants to locate sites of infection, they can also create and sculpt them as guidance cues but the mechanisms remain unclear. @robinsall &co show that macrophages extract directional information from their environment from a constant concentration of C5a #chemoattractant, self-generate a gradient & enhance guidance @PLOSBiology https://plos.io/4txkZez
