TBMs use dendrites to scavenge GC B cells; example 3. CX3CR1^GFP were primed with OVA and after 14 d received tdTomato⁺ B1-8^hi B cells followed by injection with NP-OVA to the footpad. After an additional 7 d, the mice were subjected to intervital TPLSM. Green, macrophages; red, B cells.

Tingible body macrophages arise from lymph node–resident precursors and uptake B cells by dendrites
