Immunohistochemical labeling of tumor thin sections with CD8 (red) antibodies and DAPI (blue) nuclear stain. A: Two typical sections from an untreated control tumor collected 14 days after injecting tumor cells into the liver; B. Two typical sections of a secondary tumor that was fixed 7 days after it was injected into a liver in which the primary tumor had been nanoelectroablated 3 weeks earlier. This secondary tumor exhibited growth inhibition and a photograph of it can be seen in Fig 5B; C. Percentage of cells expressing CD8 in histological sections of tumors from four different conditions. Each bar represents the mean of measurements taken from 3–7 sections of 2 separate tumors. The untreated tumors were fixed 14 days after injection; “ns+7d” represents tumors fixed 7days after treating with 400 pulses, 15 kV, 100ns; “T2+7d” represents secondary tumors fixed 7 days after injection. CD8 concentration is significantly different from control tumor levels with **p = 0.002; “T2+7d+CD9 AB” represents secondary tumors fixed 7 days after injection with CD8 antibodies injected IP 24 h prior to the tumor cell injection. The CD8 concentration is significantly different from control tumors with *p = 0.005.

Analysis of graft-infiltrating T cells. Activated CD25+ T cells and CD4+ and CD8+ T cell subsets were stained at the time points of corneal allograft rejection and calculated within the graft. A, C, and E show representative histological staining for CD25, CD4, and CD8 in grafts of treated and control animals, respectively. CD25+ (B) and CD4+ (D) cells infiltrated to a statistically significantly stronger extent in 3.2.3-treated animals when compared to control treated animals (*p<0.01, ** p<0.01). No statistical difference was observed for CD8+ T cells (NS=not significant; F).

CD3ε, CD8α, and PAX5 immunostainings. (A–D) CD3ε staining in the zone of the foramen of Monro (fM) of the injected ventricle comprising a part of the stria medullaris [sm, (A)]. Many positive cells occurred in the perivascular spaces of the local large venules 12 h after NA injection. A detailed view (B) of the vessels in the stria medullaris (sm) shows that many positive cells have smooth nuclei while polymorphonucleated cells (arrow) are negative. (C) Twenty-four hours after the injection, some positive cells seemed to cross the ependyma of the choroid plexus (cp). (D) Positive cells were also present in the meninges (men) next to the optic chiasm (oc), and few appeared to penetrate the brain parenchyma (arrow). (E–G) Double immunofluorescence of lymphocytes in a 12 h post-injection brain section. Most CD3ε-positive cells [(E), green] found in the perivascular spaces of the large vessels were also positive for CD8α [(F), red]. (H–J) PAX5 immunostaining showing positive cells in the wall of the large vessels around the foramen of Monro [fM; (H)], although they were not as abundant as CD3ε-positive cells. Few PAX5-positive nuclei were also found in the choroid plexus (cp) of the injected lateral ventricle (I) as well as in the meninges (men) close to the optic chiasm [oc; (J)]. cp, choroid plexus; fM, foramen of Monro; men, meninges; oc, optic chiasm; sm, stria medullaris.
