Figure 2. Increases in the arbor length of white matter astrocytes after naltrexone treatment in animals exhibiting SIB.

Figure 2

The area of the astrocyte cell body was not significantly different in macaques with SIB in grey or white matter astrocytes regardless of naltrexone treatment (a–b). The cumulative length of the astrocyte processes in animals with SIB was decreased in white matter astrocytes (d) but was not significantly decreased in grey matter astrocytes (c). In both grey and white matter, total arbor length in naltrexone-treated SIB animals was increased compared with non-treated SIB animals (c–d). However, there were no significant changes in arbor volume in SIB and naltrexone-treated SIB animals compared to controls (e–f). Data shown as mean ± SD, p < 0.05. Representative traces are included at the bottom.
