Leukocyte migration to degenerating axons is enhanced in the absence of glia. (a) Leukocytes (yellow arrowheads) homed to the degenerating pLL nerve in a lysC::GFP/neuroD::GFP double transgenic larva. (b) The number of leukocytes directly in contact with degenerating axons was significantly increased in the absence of glia (AG1478). Quantitative analysis was performed between 2.5 and 4.5 hours postaxotomy. Student’s t test, P = 0.00167.
