Abstract
Nanotechnology provides many solutions to improve conventional drug delivery and has a unique niche in the areas related to the specific targeting of the immune system, such as immunotherapies and vaccines. Preclinical studies in this field rely heavily on the combination of in vitro and in vivo methods to assess the safety and efficacy of nanotechnology platforms, nanoparticle-formulated drugs, and vaccines. While certain types of toxicities can be evaluated in vitro and good in vitro-in vivo correlation has been demonstrated for such tests, animal studies are still needed to address complex biological questions and, therefore, provide a unique contribution to establishing nanoparticle safety and efficacy profiles. The genetic, metabolic, mechanistic, and phenotypic diversity of currently available animal models often complicates both the animal choice and the interpretation of the results. This review summarizes current knowledge about differences in the immune system function and immunological responses of animals commonly used in preclinical studies of nanomaterials. We discuss challenges, highlight current gaps, and propose recommendations for animal model selection to streamline preclinical analysis of nanotechnology formulations.

Abstract
We investigated the relationship between thyroid peroxidase (TPO) antibody and T lymphocyte epitopes in TPO-adenovirus (TPO-Ad) immunized BALB/c mice and mice transgenic for the human class II molecule DR3 associated with human thyroid autoimmunity. TPO autoantibodies are largely restricted to an immunodominant region (IDR). BALB/c mice immunized with fewer (10(7) vs. 10(9)) TPO-Ad particles developed TPO antibodies with lower titers that displayed greater restriction to the IDR. However, as with higher-dose TPO-Ad immunization, T cell epitopes (assessed by splenocyte interferon-gamma response to TPO in vitro) were highly diverse and variable in different animals. In contrast, DR3 mice immunized the higher TPO-Ad dose (10(9) particles) had high TPO antibody levels that showed relative focus on the IDR. Moreover, T cell epitopes recognized by splenocytes from DR3 mice showed greater restriction than BALB/c mice. Antibody affinities for TPO were higher in DR3 than in BALB/c mice. The present study indicates that weak TPO-Ad immunization of BALB/c mice (with consequent low TPO antibody titers) is required for enhanced IDR focus yet is not associated with T cell epitopic restriction. Humanized DR3 transgenic mice, despite stronger TPO-Ad immunization, develop higher titer TPO antibodies that do focus on the autoantibody IDR with T cells that recognize a more limited range of TPO peptides. These data suggest a relationship between major histocompatibility complex class II molecules and the development of antibodies to the IDR, a feature of human thyroid autoimmunity.

Abstract
Hashimoto's thyroiditis (HT) is an organ-specific T-cell mediated disease. It is a complex disease, with a strong genetic component. To date, significant progress has been made towards the identification and functional characterization of HT susceptibility genes. In this review, we will summarize the recent advances in our understanding of the genetic input to the pathogenesis of HT.

Abstract
Murine experimental autoimmune thyroiditis (EAT), characterized by thyroid destruction after immunization with thyroglobulin (Tg), has long been a useful model of organ-specific autoimmune disease. More recently, porcine thyroid peroxidase (pTPO) has also been shown to induce thyroiditis, but these results have not been confirmed. When (C57BL/6 x CBA)F(1) mice, recently shown to be susceptible to mouse TPO-induced EAT, were immunized with plasmid DNA to human TPO (hTPO) and cytokines IL-12 or GM-CSF, significant antibody (Ab) titres were generated, but minimal thyroiditis was detected in one mouse only from the TPO + GM-CSF immunized group. However, after TPO DNA immunization of HLA-DR3 transgenic class II-deficient NOD mice, thyroiditis was present in 23% of mice injected with TPO + IL-12 or GM-CSF. We also used another marker for assessing the closeness of the model to human thyroid autoimmunity by examining the epitope profile of the anti-TPO Abs to immunodominant determinants on TPO. Remarkably, the majority of the anti-TPO Abs was directed to immunodominant regions A and B, demonstrating the close replication of the model to human autoimmunity. TPO protein immunizations of HLA-DR3 transgenic mice with recombinant hTPO did not result in thyroiditis, nor did immunization of other mice expressing HLA class II transgenes HLA-DR4 or HLA-DQ8, with differential susceptibility to Tg-induced EAT. Moreover, our efforts to duplicate exactly the experimental procedures used with pTPO also failed to induce thyroiditis. The success of hTPO plasmid DNA immunization of DR3(+) mice, similar to our reports on Tg-induced thyroiditis and thyrotropin receptor DNA-induced Graves' hyperthyroidism, underscores the importance of DR3 genes for all three major thyroid antigens, and provides another humanized model to study autoimmune thyroid disease.

Abstract
Graves' disease in Caucasians is associated with the major histocompatibility (MHC) antigen HLA-DR3. One approach to studying the role of susceptibility genes involves the use of mice that lack murine MHC and instead express human HLA antigens. Although Graves' disease does not arise spontaneously in animals, thyrotropin receptor (TSHR) antibodies can be induced in mice by vaccination with TSHR-DNA in a plasmid. In the present study, we characterized TSHR antibodies and thyroiditis developing in HLA-DR3 transgenic mice vaccinated with TSHR-DNA. As controls, we used mice transgenic for HLA-DQ6b, an MHC antigen rarely associated with Graves' disease. We observed that approximately 30% of DR3-, but none of DQ6b-transgenic mice, developed TSHR antibodies detectable by enzyme-linked immunosorbent assay (ELISA). The cysteine-rich amino terminal peptide was the dominant linear antibody epitope in DR3 mice, as in other strains vaccinated with TSHR-DNA. Sera from some vaccinated DR3 mice were positive on flow cytometry using intact cells expressing the TSHR, demonstrating recognition of the native TSHR on the cell surface. Although none of the these mice had thyroid stimulating antibodies or were hyperthyroid, a few developed lymphocytic infiltration of the thyroid. These data, together with information for other mouse strains, demonstrate that MHC (human and murine) and non-MHC genes contribute to the outcome of TSHR-DNA vaccination and indicate the potential value of DR3 transgenic mice for dissecting immune responses to the TSHR.

Abstract
A critical event in the pathogenesis of experimental autoimmune thyroiditis (EAT) is the entry of thyroid-specific T lymphocytes into the thyroid gland. To investigate the role of soluble mediators in that infiltration, we have assayed the expression of various chemokines in diseased thyroid glands and in cytokine-treated cultures of normal thyroid epithelial cells. MCP-1 (monocyte chemotactic protein-1) and RANTES are produced during EAT and induced in vitro by IFN-gamma, IL-10, TNF-alpha, and IL-1beta. In vitro chemotaxis experiments using immune lymph node (LN) cells showed that RANTES attracted mTg-specific responder LN cells, whereas MCP-1 attracted mTg-specific CD4(+), CD25(+) regulator cells that secreted IL-10. The in vivo transfer of LN T cells attracted in vitro either by RANTES or by MCP-1 confirmed their opposite effects on the course of EAT.

Abstract
Experimental autoimmune thyroiditis (EAT) can be induced in genetically susceptible mice by immunization with the self antigen, thyroglobulin (Tg). Since susceptibility is linked to H2 class II molecules, we have generated human leukocyte antigen (HLA) class II transgenic mice to study potential HLA associations with Hashimoto's thyroiditis. DR3 (HLA-DRA/DRB1*0301) and DQ8 (HLA-DQA1*0301/DQB1*0302) transgenes were introduced into class II-negative Ab(0)/B10 and Ab(0) nonobese diabetic (Ab(0)/NOD) mice. Previous work had shown that DR3 transgenic mice were susceptible to both mouse Tg and human Tg-induced EAT, whereas DQ8 transgenic mice were moderately susceptible only to human Tg induction. In this report, we examined the effect of DQ8 transgene on mouse Tg- and human Tg-induced EAT in double transgenic DR3/DQ8 mice. After mouse Tg induction, thyroiditis in DR3(+)DQ8(+) Ab(0)/B10 mice was significantly less severe than in DR3(+) mice but more severe than in DQ8(+) mice. No difference in thyroiditis was observed between DR3(+) and DR3(+)DQ8(+) mice in another background strain, Ab(0)/NOD. However, after immunization with human Tg, DQ8 coexpression downregulated thyroiditis severity, compared to DR3(+) mice, whereas thyroiditis was more extensive than in DQ8(+) mice. Thus, depending on the background strain and the Tg used to induce disease, the presence of the DQ8 transgene can reduce thyroiditis mediated by DR3 molecules.

Abstract
Experimental autoimmune thyroiditis (EAT) is inducible in genetically susceptible mice by immunization with mouse thyroglobulin (mTg). With susceptibility linked to MHC class II, EAT is useful in studying human leukocyte antigen (HLA) associations with Hashimoto's thyroiditis. In non-obese diabetic (NOD) mice, approximately 10% thyroiditis incidence occurs with aging. This potential was exploited to examine the T cell repertoire and HLA association in EAT. Similar to B10.K-Vbeta(c)mice with TCRBV genes reduced by approximately 70%, mTg-immunized NOD-Vbeta(c)mice developed thyroiditis comparable to controls, indicating plasticity of the TCR repertoire for pathogenic epitopes. HLA association was evaluated by introducing HLA-DRA/DRB1*0301 (DR3) transgene into class II-negative NOD mice (Ab(0)/NOD). Previously, this HLA-DR3 transgene rendered EAT-resistant B10.M and Ab(0)mice susceptible to both mTg- and hTg-induced EAT. These results are now confirmed. mTg-induced thyroiditis in DR3+ Ab(0)/NOD mice was comparable to that in NOD and DR3- NOD mice, and the proliferative response was stronger. By comparison, NOD mice were only moderately susceptible to hTg-induced EAT. However, thyroiditis was more severe in DR3+ Ab(0)/NOD than in DR3- NOD mice, with no difference in proliferative response to hTg harbouring heterologous epitopes. The confirmed permissiveness of HLA-DR3 molecules on an NOD background for EAT induction by both mTg and hTg supports the importance of this class II gene implicated in some patient studies.
