From: HSV-mediated expression of interleukin-4 in dorsal root ganglion neurons reduces neuropathic pain
(a) Schematic representation of vector S4IL4. The control vector SHZ was identical to S4IL4, except that the inserted cassette contained the E. coli lacZ reporter gene under the control of the HCMV IEp in the tk locus. (b) Immunofluorescent staining shows IL-4 expression in large and small neurons in the DRG 1 week after subcutaneous inoculation of vector S4IL4.
