(A) Cluster of expanded Vβ1 + T cells within multiple sclerosis (MS) lesions. Immunohistochemistry for the expanded and persisting Vβ1 clone (green) in clusters of <t>CD8</t> + T cells (red) in parenchymal MS lesions. Several such clusters were observed. Only very few scattered CD8 − Vβ1 + T cells could be identified in the brain lesion. Nuclei are visualized with 4',6-diamidino-2-phenylindole (white). Scale bar 20 µm. (B) Sequences of paired T-cell receptor (TCR) α and β chains. Single sorted or laser microdissected Vβ1 + CD8 + T cells from peripheral blood or brain sections were submitted to single-cell TCR PCR to identify Vβ1 chains and all possible matching α chains. The V, n(D)n, and J regions are indicated. Amino acids encoded by n(D)n nucleotides are printed in red. The expanded Vβ1-Jβ2.3 β chain (upper line) was found to pair with 4 different α chains. Three α chains were identified from brain lesions, and 1 α chain was found in blood. The α chains expressing the Jα33 (second line) and Jα16 (fifth line) elements were identified in 7 and 6 independent cells, respectively. All α chains share the Vα7.2 element, and even though they do not share the same Jα element, they all show homologous complementarity determining region 3α regions with a conserved valine (V) followed by a positively charged arginine (R) (with only one clone showing a glutamine [Q]), a negatively charged amino acid (D/E), and a relatively large hydrophilic amino acid. One of the α chains (highlighted in red) is the mucosal-associated invariant T (MAIT) cell canonical TCR Vα7.2-CAXXDSNYQLIW-Jα33 chain with 2 N nucleotide–encoded amino acids between Vα7.2 and Jα33 (here VR). The other clones with Jα16, Jα24.1, and Jα58 chains are atypical for MAIT cells, which usually carry Jα33, Jα20, or Jα12. PBMC = peripheral blood mononuclear cell.

Comparison of cellular immunity in different groups: ( A ) Statistical analysis of the peripheral blood lymphocyte stimulation index in the ND groups. Under ConA stimulation, the SI values of peripheral blood lymphocytes in the PBS group were significantly lower than those of the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p < 0.001). The SI values of peripheral blood lymphocytes in the rAd5-EGFP group were significantly lower than those in the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p < 0.01). However, there was no significant difference between the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p > 0.05), and no significant differences between the PBS and rAd5-EGFP groups ( p > 0.05). Under inactivated NDV stimulation, the SI values of peripheral blood lymphocytes in the PBS and rAd5-EGFP groups were significantly lower than those in the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p < 0.0001). SI values in the rAd-VP2-F2A-F group were significantly different from those of the rDHN3-mF and rAd5-F groups ( p < 0.05); no significant differences between the rDHN3-mF and rAd5-F groups ( p > 0.05), and there was no significant difference between the PBS and rAd5-EGFP groups ( p > 0.05) (ns—non-significant; * p < 0.05); ( B ) Statistical analysis of the peripheral blood lymphocyte stimulation index in IBD groups. From ( D ) above, it can be seen that the SI values of peripheral blood lymphocytes in the HVT-VP2 vector vaccines group, rAd5-VP2 group, and rAd5-VP2-F2A-F group were not significantly different from each other regardless of ConA stimulation or inactivated IBDV stimulation in the IBD group ( p > 0.05). However, the SI values of the above three groups were significantly higher than those of the rAd5- EGFP and the PBS groups ( p < 0.05). There was no significant difference between the PBS and rAd5-EGFP groups ( p > 0.05) (ns—non-significant); ( C , D ) Statistical analysis of the percentage of CD4+ and CD8+ T lymphocytes in the peripheral blood in ND groups. It can be seen from these two pictures that the percentages of CD4+ and CD8+ T lymphocytes in the rAd5-F, rDHN3-mF, and rAd5-VP2-F2A-F groups were significantly higher than those in the PBS group ( p < 0.05). There was no significant difference between the above three vaccine groups ( p > 0.05); ( E , F ) Statistical analysis of the percentage of CD4+ and CD8+ T lymphocytes in the peripheral blood in the IBD groups. It can be seen from these two pictures that the percentage of CD4+ and CD8+ T lymphocytes in the rAd5-VP2 group, the HVT-VP2 vector vaccines, and rAd5-VP2-F2A-F groups were significantly higher than in the PBS group ( p < 0.05). There was no significant difference between the three vaccine groups ( p > 0.05).

(A) Cluster of expanded Vβ1 + T cells within multiple sclerosis (MS) lesions. Immunohistochemistry for the expanded and persisting Vβ1 clone (green) in clusters of CD8 + T cells (red) in parenchymal MS lesions. Several such clusters were observed. Only very few scattered CD8 − Vβ1 + T cells could be identified in the brain lesion. Nuclei are visualized with 4',6-diamidino-2-phenylindole (white). Scale bar 20 µm. (B) Sequences of paired T-cell receptor (TCR) α and β chains. Single sorted or laser microdissected Vβ1 + CD8 + T cells from peripheral blood or brain sections were submitted to single-cell TCR PCR to identify Vβ1 chains and all possible matching α chains. The V, n(D)n, and J regions are indicated. Amino acids encoded by n(D)n nucleotides are printed in red. The expanded Vβ1-Jβ2.3 β chain (upper line) was found to pair with 4 different α chains. Three α chains were identified from brain lesions, and 1 α chain was found in blood. The α chains expressing the Jα33 (second line) and Jα16 (fifth line) elements were identified in 7 and 6 independent cells, respectively.

Analysis of the T-cell receptor (TCR) Vα7.2 repertoire of patient A by pyrosequencing shows oligoclonal T-cell expansions in different samples. Each pie chart represents the total number of nucleotide sequences found in the Vα7.2 repertoire of a certain compartment and each sector represents one distinct T-cell clone. We compared (A) samples from CNS tissue from the biopsy taken in 1996, (B) Vα7.2 + CD161 + mucosal-associated invariant T (MAIT) cells, (C) Vα7.2 + CD161 − cells, (D) CD8 + cells, and (E) CD4 + T cells from peripheral blood taken in 2013 and 2014. For each population we list the designation of the Jα elements and their relative percentage. Clones carrying the MAIT canonical TCR α chain (CAXXDSNYQLIW) are marked in bright blue, and clones containing the noncanonical α chains characterized by Jα12 (CAXXDSSYKLIF) and Jα20 (CAVXXDYKLSF) are marked in dark blue and light blue, respectively. (F) Percentages of identical complementarity determining region 3α amino acid sequences within the TCR Vα7.2 + repertoire between the different samples defined above (A–E). The numbers are percentages indicating how often a particular sequence detected in one sample was also found in another sample. The greatest overlap was between Vα7.2 + CD161 + and CD8 + T cells from peripheral blood, but there was also significant overlap between the CNS sample and the Vα7.2 + CD161 + sample from 2013 to 2014, as highlighted by the red and yellow colors.

Comparison of cellular immunity in different groups: ( A ) Statistical analysis of the peripheral blood lymphocyte stimulation index in the ND groups. Under ConA stimulation, the SI values of peripheral blood lymphocytes in the PBS group were significantly lower than those of the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p < 0.001). The SI values of peripheral blood lymphocytes in the rAd5-EGFP group were significantly lower than those in the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p < 0.01). However, there was no significant difference between the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p > 0.05), and no significant differences between the PBS and rAd5-EGFP groups ( p > 0.05). Under inactivated NDV stimulation, the SI values of peripheral blood lymphocytes in the PBS and rAd5-EGFP groups were significantly lower than those in the rDHN3-mF, rAd5-F, and rAd5-VP2-F2A-F groups ( p < 0.0001).

However, the SI values of the above three groups were significantly higher than those of the rAd5- EGFP and the PBS groups ( p < 0.05).
