NSF = no significant findings, N.D = Not determined.
CD8 + cells in the brain - scoring: 0 = no immunopositive cells observed in section; + = rare scattered cells;
Note that CD4 cells are artificially increased due to CD8-depletion and are therefore not useful for diagnosis of AIDS in the CD8-depleted macaque model of NeuroAIDS.
