From: Sigma-1 receptor expression in sensory neurons and the effect of painful peripheral nerve injury
Effect of injury on σ1 receptor (σ1R) expression in sensory neurons identified by neurofilament-200 (NF-200) staining. (A) Staining of σ1R was distributed within cytoplasmic areas of all NF-200 co-expressing neurons. σ1R immunofluorescence intensity was decreased in both spinal nerve ligation (SNL) 4th lumbar (L4) and 5th lumbar (L5) neurons compared with Control. (B) Summary data showed decrease of intensity of σ1R staining in IB4-positive SNL L4 and L5 neurons. Mean ± SEM; number in bars represents the sample size; **p < 0.01, ***p < 0.001.
