Percentages of BrdU+, Mac387+, CD68+ and SIVp28+ cells in SIVE lesions.

#Mean±SEM (standard error of the mean) of the percentage of BrdU+ cells in SIVE lesions calculated as followed; (number of BrdU+ cells/total number of cells in lesions using hematoxylin) ×100.*Mean±SEM of the percentage of BrdU+ cells expressing Mac387 in SIVE lesions calculated as followed; (number of BrdU+Mac387+ cells/total number of BrdU+ cells) ×100.**Mean±SEM of the percentage of BrdU+ cells expressing CD68 in SIVE lesions calculated as followed; (number of BrdU+CD68+ cells/total number of BrdU+ cells) ×100.***Mean±SEM of the percentage of BrdU+ cells expressing SIVp28 in SIVE lesions calculated as followed; (number of BrdU+SIVp28+ cells/total number of BrdU+ cells) ×100.‡Mean±SEM of the percentage of Mac387+ cells expressing BrdU in SIVE lesions calculated as followed; (number of BrdU+Mac387+ cells/total number of Mac387+ cells) ×100.‡‡Mean±SEM of the percentage of CD68+ cells expressing BrdU in SIVE lesions calculated as followed; (number of BrdU+CD68+ cells/total number of CD68+ cells) ×100.‡‡‡Mean±SEM of the percentage of SIVp28+ cells expressing BrdU in SIVE lesions calculated as followed; (number of BrdU+SIVp28+ cells/total number of SIVp28+ cells) ×100.n = number of total lesions examined. For 244-96 frontal cortex, prefrontal cortex and basal nuclei and for DB79 frontal cortex and occipital cortex sections were examined. The mild SIVE animal, 55-05, had similar percentages of BrdU+ cells, BrdU+Mac387+ and BrdU+CD68+ cells in lesions compared to DB79 and 244-96, but there were fewer lesions overall.
