Abstract
BACKGROUND Minor histocompatibility antigen (miHA) vaccines have the potential to augment graft-versus-tumor effects without graft-versus-host disease (GVHD). We used mixed hematopoietic chimerism in the canine model of major histocompatibility complex-matched allogeneic hematopoietic cell transplantation as a platform to develop a miHA vaccination regimen. METHODS We engineered DNA plasmids and replication-deficient human adenovirus type 5 constructs encoding large sections of canine SMCY and the entire canine SRY gene. RESULTS Priming with replication-deficient human adenovirus type 5 constructs and boosting with ex vivo plasmid-transfected dendritic cells and cutaneous delivery of plasmids with a particle-mediated epidermal delivery device (PMED) in 2 female dogs induced antigen-specific T-cell responses. Similar responses were observed after a prime-boost vaccine regimen in three female hematopoietic cell transplantation donors. Subsequent donor lymphocyte infusion resulted in a significant change of chimerism in 1 of 3 male recipients without any signs of graft-versus-host disease. The change in chimerism in the recipient occurred in association with the development of CD4+ and CD8+ T-cell responses to the same peptide pools detected in the donor. CONCLUSIONS These studies describe the first in vivo response to miHA vaccination in a large, outbred animal model without using recipient cells to sensitize the donor. This model provides a platform for ongoing experiments designed to define optimal miHA targets and develop protocols to directly vaccinate the recipient.

Abstract
The HIV vaccine strategy that, to date, generated immune protection consisted of a prime-boost regimen using a canarypox vector and an HIV envelope protein with alum, as shown in the RV144 trial. Since the efficacy was weak, and previous HIV vaccine trials designed to generate antibody responses failed, we hypothesized that generation of T cell responses would result in improved protection. Thus, we tested the immunogenicity of a similar envelope-based vaccine using a mouse model, with two modifications: a clade C CN54gp140 HIV envelope protein was adjuvanted by the TLR9 agonist IC31®, and the viral vector was the vaccinia strain NYVAC-CN54 expressing HIV envelope gp120. The use of IC31® facilitated immunoglobulin isotype switching, leading to the production of Env-specific IgG2a, as compared to protein with alum alone. Boosting with NYVAC-CN54 resulted in the generation of more robust Th1 T cell responses. Moreover, gp140 prime with IC31® and alum followed by NYVAC-CN54 boost resulted in the formation and persistence of central and effector memory populations in the spleen and an effector memory population in the gut. Our data suggest that this regimen is promising and could improve the protection rate by eliciting strong and long-lasting humoral and cellular immune responses.

Abstract
Recombinant viruses hold promise as vectors for vaccines to prevent infectious diseases with significant global health impacts. One of their major limitations is that preexisting anti-vector neutralizing antibodies can reduce T cell responses to the insert antigens; however, the impact of vector-specific cellular immunity on subsequent insert-specific T cell responses has not been assessed in humans. Here, we have identified and compared adenovirus-specific and HIV-specific T cell responses in subjects participating in two HIV-1 vaccine trials using a vaccine vectored by adenovirus serotype 5 (Ad5). Higher frequencies of pre-immunization adenovirus-specific CD4⁺ T cells were associated with substantially decreased magnitude of HIV-specific CD4⁺ T cell responses and decreased breadth of HIV-specific CD8⁺ T cell responses in vaccine recipients, independent of type-specific preexisting Ad5-specific neutralizing antibody titers. Further, epitopes recognized by adenovirus-specific T cells were commonly conserved across many adenovirus serotypes, suggesting that cross-reactivity of preexisting adenovirus-specific T cells can extend to adenovirus vectors derived from rare serotypes. These findings provide what we believe to be a new understanding of how preexisting viral immunity may impact the efficacy of vaccines under current evaluation for prevention of HIV, tuberculosis, and malaria.

Abstract
A full-length (6.1-kb) human genomic pim-1 gene, together with its immediate 5'-upstream promoter sequence (Ppim) was isolated and sequenced. The human pim-1 gene shares an overall nucleotide (nt) sequence identity of 53% with the previously reported murine pim-1 gene. It consists of six exons and five introns and contains a protein-coding region that is identical in nt sequence to a full-length human pim-1 cDNA. The gene codes for a predicted Pim-1 protein of 313 amino acids (aa) with an Mr of 35,690 and a pI of 5.7. The deduced aa sequence of the human Pim-1 has 94% identity with the murine Pim-1 whereas the nt sequences of the two genes are 88% identical. All of the conserved aa residues of the mouse pim-1 gene, which are homologous to known protein kinases are conserved in the predicted human protein. The human Ppim region is very G + C-rich (69%) and shares greater than 80% identity with the murine Ppim. The Ppim has no TATA- or CAAT-box sequences but does contain a number of nt sequences similar to the putative binding sites of several presumptive transcription factors.
