Abstract

The identification of "asymptomatic" (i.e., protective) epitopes recognized by T cells from herpes simplex virus (HSV)-seropositive healthy individuals is a prerequisite for an effective vaccine. Using the PepScan epitope mapping strategy, a library of 179 potential peptide epitopes (15-mers overlapping by 10 amino acids) was identified from HSV type 1 (HSV-1) glycoprotein B (gB), an antigen that induces protective immunity in both animal models and humans. Eighteen groups (G1 to G18) of 10 adjacent peptides each were first screened for T-cell antigenicity in 38 HSV-1-seropositive but HSV-2-seronegative individuals. Individual peptides within the two immunodominant groups (i.e., G4 and G14) were further screened with T cells from HLA-DR-genotyped and clinically defined symptomatic (n = 10) and asymptomatic (n = 10) HSV-1-seropositive healthy individuals. Peptides gB161-175 and gB166-180 within G4 and gB661-675 within G14 recalled the strongest HLA-DR-dependent CD4+ T-cell proliferation and gamma interferon production. gB166-180, gB661-675, and gB666-680 elicited ex vivo CD4+ cytotoxic T cells (CTLs) that lysed autologous HSV-1- and vaccinia virus (expressing gB)-infected lymphoblastoid cell lines. Interestingly, gB166-180 and gB666-680 peptide epitopes were strongly recognized by CD4+ T cells from 10 of 10 asymptomatic patients but not by CD4+ T cells from 10 of 10 symptomatic patients (P < 0.0001; analysis of variance posttest). Inversely, CD4+ T cells from symptomatic patients preferentially recognized gB661-675 (P < 0.0001). Thus, we identified three previously unrecognized CD4+ CTL peptide epitopes in HSV-1 gB. Among these, gB166-180 and gB666-680 appear to be "asymptomatic" peptide epitopes and therefore should be considered in the design of future herpes vaccines.

<div type="abstract" xml:lang="en">The identification of "asymptomatic" (i.e., protective) epitopes recognized by T cells from herpes simplex virus (HSV)-seropositive healthy individuals is a prerequisite for an effective vaccine. Using the PepScan epitope mapping strategy, a library of 179 potential peptide epitopes (15-mers overlapping by 10 amino acids) was identified from HSV type 1 (HSV-1) glycoprotein B (gB), an antigen that induces protective immunity in both animal models and humans. Eighteen groups (G1 to G18) of 10 adjacent peptides each were first screened for T-cell antigenicity in 38 HSV-1-seropositive but HSV-2-seronegative individuals. Individual peptides within the two immunodominant groups (i.e., G4 and G14) were further screened with T cells from HLA-DR-genotyped and clinically defined symptomatic (n = 10) and asymptomatic (n = 10) HSV-1-seropositive healthy individuals. Peptides gB
<sub>161-175</sub>
and gB
<sub>166-180</sub>
within G4 and gB
<sub>661-675</sub>
within G14 recalled the strongest HLA-DR-dependent CD4
<sup>+</sup>
T-cell proliferation and gamma interferon production. gB
<sub>166-180,</sub>
gB
<sub>661-675</sub>
, and gB
<sub>666-680</sub>
elicited ex vivo CD4
<sup>+</sup>
cytotoxic T cells (CTLs) that lysed autologous HSV-1- and vaccinia virus (expressing gB)-infected lymphoblastoid cell lines. Interestingly, gB
<sub>166-180</sub>
and gB
<sub>666-680</sub>
peptide epitopes were strongly recognized by CD4
<sup>+</sup>
T cells from 10 of 10 asymptomatic patients but not by CD4
<sup>+</sup>
T cells from 10 of 10 symptomatic patients (P < 0.0001; analysis of variance posttest). Inversely, CD4
<sup>+</sup>
T cells from symptomatic patients preferentially recognized gB
<sub>661-675</sub>
(P < 0.0001). Thus, we identified three previously unrecognized CD4
<sup>+</sup>
CTL peptide epitopes in HSV-1 gB. Among these, gB
<sub>166-180</sub>
and gB
<sub>666-680</sub>
appear to be "asymptomatic" peptide epitopes and therefore should be considered in the design of future herpes vaccines.</div>

<s0>The identification of "asymptomatic" (i.e., protective) epitopes recognized by T cells from herpes simplex virus (HSV)-seropositive healthy individuals is a prerequisite for an effective vaccine. Using the PepScan epitope mapping strategy, a library of 179 potential peptide epitopes (15-mers overlapping by 10 amino acids) was identified from HSV type 1 (HSV-1) glycoprotein B (gB), an antigen that induces protective immunity in both animal models and humans. Eighteen groups (G1 to G18) of 10 adjacent peptides each were first screened for T-cell antigenicity in 38 HSV-1-seropositive but HSV-2-seronegative individuals. Individual peptides within the two immunodominant groups (i.e., G4 and G14) were further screened with T cells from HLA-DR-genotyped and clinically defined symptomatic (n = 10) and asymptomatic (n = 10) HSV-1-seropositive healthy individuals. Peptides gB
<sub>161-175</sub>
and gB
<sub>166-180</sub>
within G4 and gB
<sub>661-675</sub>
within G14 recalled the strongest HLA-DR-dependent CD4
<sup>+</sup>
T-cell proliferation and gamma interferon production. gB
<sub>166-180,</sub>
gB
<sub>661-675</sub>
, and gB
<sub>666-680</sub>
elicited ex vivo CD4
<sup>+</sup>
cytotoxic T cells (CTLs) that lysed autologous HSV-1- and vaccinia virus (expressing gB)-infected lymphoblastoid cell lines. Interestingly, gB
<sub>166-180</sub>
and gB
<sub>666-680</sub>
peptide epitopes were strongly recognized by CD4
<sup>+</sup>
T cells from 10 of 10 asymptomatic patients but not by CD4
<sup>+</sup>
T cells from 10 of 10 symptomatic patients (P < 0.0001; analysis of variance posttest). Inversely, CD4
<sup>+</sup>
T cells from symptomatic patients preferentially recognized gB
<sub>661-675</sub>
(P < 0.0001). Thus, we identified three previously unrecognized CD4
<sup>+</sup>
CTL peptide epitopes in HSV-1 gB. Among these, gB
<sub>166-180</sub>
and gB
<sub>666-680</sub>
appear to be "asymptomatic" peptide epitopes and therefore should be considered in the design of future herpes vaccines.</s0>
