Abstract
In a context where injection of antigen (Ag)-specific T cells probably represents the future of leukemia immunotherapy, identification of optimal target Ags is crucial. We therefore sought to discover a reliable marker for selection of the most potent Ags. To this end, (1) we immunized mice against 8 individual Ags: 4 minor histocompatibility Ags (miHAs) and 4 leukemia-associated Ags (LAAs) that were overexpressed on leukemic relative to normal thymocytes; (2) we assessed their ability to reject EL4 leukemic cells; and (3) we correlated the properties of our Ags (and their cognate T cells) with their ability to induce protective antileukemic responses. Overall, individual miHAs instigated more potent antileukemic responses than LAAs. Three features had no influence on the ability of primed T cells to reject leukemic cells: (1) MHC-peptide affinity; (2) the stability of MHC-peptide complexes; and (3) epitope density at the surface of leukemic cells, as assessed using mass spectrometry. The cardinal feature of successful Ags is that they were recognized by high-avidity CD8 T cells that proliferated extensively in vivo. Our work suggests that in vitro evaluation of functional avidity represents the best criterion for selection of Ags, which should be prioritized in clinical trials of leukemia immunotherapy.

Abstract
The human HLA-A2-restricted CD8(+) T cell response to influenza A virus (IAV) is largely directed against the matrix protein-derived M1(58-66) epitope and represents an archetypal example of CD8(+) T cell immunodominance. In this study, we examined the CD8(+) T cell hierarchy to M1(58-66) and two subdominant IAV-specific epitopes: NS1(122-130) and PA(46-55) in HLA-A2(+) human subjects and HLA-A2.1 transgenic (HHD) mice. Using epitope-based lipopeptides, we show that the CD8(+) T cell hierarchy induced by IAV infection could also be induced by lipopeptide vaccination in a context outside of viral infection when the Ag load is equalized. In the HHD HLA-A2.1 mouse model, we show that the naive T cell precursor frequencies, and competition at the Ag presentation level, can predict the IAV-specific CD8(+) T cell hierarchy. Immunization of mice with subdominant epitopes alone was unable to overcome the dominance of the M1(58-66)-specific response in the face of IAV challenge; however, a multiepitope vaccination strategy was most effective at generating a broad and multispecific response to infection.

Abstract
Previous studies of CD8(+) T cell immunodominance after primary virus infection of F(1) mice compared with their inbred parents have generally concluded that no dramatic changes occur. In this study, we revisit this issue using vaccinia virus (VACV), which has a large genome, a recently defined immunodominance hierarchy in mice, and is a candidate vector for vaccines. We found that immunogenicity of VACV peptides defined using inbred mice was highly variable in F(1) progeny: some peptides were equally immunogenic in F(1) and inbred, whereas others elicited responses that were reduced by >90% in F(1) mice. Furthermore, the dominance of a peptide in the relevant inbred parent did not predict whether it would be poorly immunogenic in F(1) mice. This result held using F(1) hybrids of MHC-congenic mice, suggesting that MHC differences alone were responsible. It was also extended to foreign epitopes expressed by an rVACV vaccine. F(1) mice were less able to mount responses to the poorly immunogenic peptides when used as a sole immunogen, ruling out immunodomination. In addition, conserved TCR Vbeta usage between inbred and F(1) mice did not always correlate with strong responses in F(1) mice. However, direct estimation of naive precursor numbers showed that these were reduced in F(1) compared with inbred mice for specificities that were poorly immunogenic in the hybrids. These data have implications for our understanding of the extent to which MHC diversity alters the range of epitopes that are immunogenic in outbred populations.

Abstract
BACKGROUND H60 is a hematopoietic cell-specific dominant minor histocompatibility antigen that is considered to be ideal for modeling leukemia treatment after bone-marrow transplantation. We characterized the H60-specific CD8 T-cell response as CD4 help dependent. This study investigated the T-cell receptor (TCR) repertoires during the evolution of H60-specific CD8 T-cell responses and influence of CD4 help on the diversity. METHODS Ex vivo TCR V beta and complementarity-determining region 3 length spectratypic and clonotypic analyses were performed using H60-tetramer-binding CD8 T cells purified from the mice undergoing the primary, secondary, and tertiary responses with cognate help, and the secondary response with noncognate separate CD4 help. RESULTS Involvement of a broad spectrum of TCRs was observed in the H60-specific primary response. With the involvement of diverse V beta families in the secondary and tertiary responses, complementarity-determining region 3 length and clonotypic diversities within the V beta subfamilies gradually decreased throughout the response evolution. In tertiary repertoires, the usage of V beta 8.3 and focused clonal usage within each V beta subfamily were prominent. When noncognate separate CD4 help was provided during the induction of H60-specific secondary responses, extremely limited TCRs constituted the repertoire of reactive CD8 T cells, and most of these TCRs coincided with those observed in the secondary or tertiary repertoires provided with cognate help. CONCLUSIONS This study is the first to characterize the diversity of TCRs specific for hematopoietic cell-specific mouse minor H antigens and demonstrate the effect of CD4 help on CD8 TCR repertoire diversity. Our data provide a basis for modeling therapeutic applications.

Abstract
BACKGROUND Injection of CD8 T cells primed against immunodominant minor histocompatibility antigens (MiHA) such as H7(a) can eradicate leukemia and solid tumors. To understand why MiHA-targeted T cells have such a potent antitumor effect it is essential to evaluate their in vivo behavior. In the present work, we therefore addressed two specific questions: what is the proliferative dynamics of H7(a)-specifc T cells in tumors, and do H7(a)-specific T cells persist long-term after adoptive transfer? METHODOLOGY/PRINCIPAL FINDINGS By day 3 after adoptive transfer, we observed a selective infiltration of melanomas by anti-H7(a) T cells. Over the next five days, anti-H7(a) T cells expanded massively in the tumor but not in the spleen. Thus, by day 8 after injection, anti-H7(a) T cells in the tumor had undergone more cell divisions than those in the spleen. These data strongly suggest that anti-H7(a) T cells proliferate preferentially and extensively in the tumors. We also found that two host factors regulated long-term persistence of anti-H7(a) memory T cells: thymic function and expression of H7(a) by host cells. On day 100, anti-H7(a) memory T cells were abundant in euthymic H7(a)-negative (B10.H7(b)) mice, present in low numbers in thymectomized H7(a)-positive (B10) hosts, and undetectable in euthymic H7(a)-positive recipients. CONCLUSIONS/SIGNIFICANCE Although in general the tumor environment is not propitious to T-cell invasion and expansion, the present work shows that this limitation may be overcome by adoptive transfer of primed CD8 T cells targeted to an immunodominant MiHA (here H7(a)). At least in some cases, prolonged persistence of adoptively transferred T cells may be valuable for prevention of late cancer relapse in adoptive hosts. Our findings therefore suggest that it may be advantageous to target MiHAs with a restricted tissue distribution in order to promote persistence of memory T cells and thereby minimize the risk of cancer recurrence.

Abstract
Restriction of T cell responses to a few epitopes (immunodominance) is a central feature of immune responses. We analyzed the entire transcriptome of effector CD8 T cells specific for a dominant (H7(a)) and a cryptic (HY) mouse Ag and performed a longitudinal analysis of selected T cell differentiation markers. We found that Ag specificity had a relatively modest influence on the repertoire of genes that are transcriptionally modulated by the CD8 T cell differentiation program. Although the differentiation programs of anti-H7(a) and anti-HY T cells were similar, they did not progress simultaneously. The expansion peak of anti-H7(a) T cells was reached on day 10 while that of anti-HY T cells was attained on days 15-20. Between days 10 and 20, anti-H7(a) T cells were in the contraction phase and anti-HY T cells in the expansion phase. Furthermore, expansion and development of effector function were well-synchronized in anti-H7(a) T cells but were disconnected in anti-HY T cells. We propose that, by leading to selective expansion of the fittest CD8 T cells, immunodominance may be beneficial to the host. Inhibition of the T cell response to cryptic Ag would ensure that host resources (APC, cytokines) for which T cells compete are devoted to T cells with the best effector potential. One implication is that favoring expansion of the fittest effector T cells in general may be more important than increasing the diversity of the T cell repertoire.

Abstract
BACKGROUND Very little is known about the immunodominance patterns of HIV-1-specific T cell responses during primary HIV-1 infection and the reasons for human lymphocyte antigen (HLA) modulation of disease progression. METHODS AND FINDINGS In a cohort of 104 individuals with primary HIV-1 infection, we demonstrate that a subset of CD8(+) T cell epitopes within HIV-1 are consistently targeted early after infection, while other epitopes subsequently targeted through the same HLA class I alleles are rarely recognized. Certain HLA alleles consistently contributed more than others to the total virus-specific CD8(+) T cell response during primary infection, and also reduced the absolute magnitude of responses restricted by other alleles if coexpressed in the same individual, consistent with immunodomination. Furthermore, individual HLA class I alleles that have been associated with slower HIV-1 disease progression contributed strongly to the total HIV-1-specific CD8(+) T cell response during primary infection. CONCLUSIONS These data demonstrate consistent immunodominance patterns of HIV-1-specific CD8(+) T cell responses during primary infection and provide a mechanistic explanation for the protective effect of specific HLA class I alleles on HIV-1 disease progression.

Abstract
Mouse models of orthopoxvirus disease provide great promise for probing basic questions regarding host responses to this group of pathogens, which includes the causative agents of monkeypox and smallpox. However, some essential tools for their study that are taken for granted with other mouse models are not available for these viruses. Here we map and characterize the initial CD8+ T-cell determinants for poxviruses in H-2d-haplotype mice. CD8+ T cells recognizing these three determinants make up around 40% of the total responses to vaccinia virus during and after resolution of infection. We then use these determinants to test if predicted conservation across orthopoxvirus species matches experimental observation and find an unexpectedly cross-reactive variant peptide encoded by ectromelia (mousepox) virus.
