1 9764850 To assess antibody responses to potential melanoma/melanocyte autoantigens, the open-reading frame sequences of tyrosinase, tyrosinase-related protein (TRP)-1, TRP-2, and melanoma-associated glycoprotein antigen family (gp100/pmel17) genes were cloned and expressed as recombinant proteins in E. coli.
2 9856813 We examined antibody responses to a melanocyte autoantigen, tyrosinase-related protein-2 (TRP-2), as it is highly expressed in cutaneous melanoma and melanocytes.
3 10078966 Of perhaps greater clinical interest, genetic immunization using cDNA encoding the normal, germline-encoded murine melanosomal protein tyrosinase-related protein-2 (TRP-2) resulted in delayed outgrowth of TRP-2+ B16 melanoma in mice and was associated with an in vivo activation of TRP-2-specific cytotoxic T lymphocytes.
4 10340547 Mouse bone marrow-derived DCs were genetically modified with lymphotactin (Lptn) by adenovirus vector, which conferred on DCs preferential chemotaxis to CD4+ and CD8+ T cells (Cao et al., 1998).
5 10340547 In both tumor models, immunization with 4 X 10(4) tumor RNA-pulsed Lptn-DCs induced more potent CTL activity, compared with their counterparts, specifically against tumor cells and Mut1 or tyrosinase-related protein 2 (TRP-2) peptide-pulsed RMA-S cells, and rendered the immunized mice resistant to tumor challenge much more effectively.
6 10340547 CD8+ T cells were necessary and sufficient to generate the protection of Lptn-DC-based RNA tumor vaccines, and CD4+ T cells were required for the induction of tumor rejection.
7 10728600 Genetic immunization of mice with human TRP2 resulted in coat depigmentation as a sign of autoimmune-mediated destruction of melanocytes and provided significant protection against metastatic growth of B16 melanoma Induction of protective immunity was associated with TRP2-reactive antibodies and CD8+ T cells.
8 10779556 We demonstrated that peripheral T cell tolerance toward murine melanoma self-antigens gp100 and TRP-2 can be broken by an autologous oral DNA vaccine containing the murine ubiquitin gene fused to minigenes encoding peptide epitopes gp100(25-33) and TRP-2(181-188).

16 11507070 The tumor-protective immunity was mediated by MHC class I antigen- restricted CD8(+) T cells together with CD4(+) T cell help, which was required only for tumor cell killing in the effector phase of the immune response.
17 11507070 The immunological mechanisms involved in this antitumor effect were suggested by a decisively increased secretion of tumor necrosis factor alpha TNFTnTNa and IFN-gamma from CD4(+) and CD8(+) T cells and a markedly up-regulated expression on CD8(+) T cells of high-affinity IL-2 receptor alpha chain (CD25), costimulatory molecule CD28, and adhesion molecule lymphocyte function-associated antigen-2 (LFA-2/CD2).
18 11863419 We developed a polyvalent melanoma gene vaccine using a plasmid vector to deliver the immunogenic human melanoma-associated antigens (MAAs) gp100 and TRP-2.

38 12944987 A mouse glioblastoma cell line, termed GL261, was shown to express high levels of proteins involved in melanin biosynthesis such as the tyrosinase-related protein-2 (TRP-2), which is commonly overexpressed in melanoma cells.
39 12944987 Mice injected with GL261 cells developed a CD8(+) T-cell response to TRP-2 and a DNA vaccine expressing human (h)TRP-2 induced CD8(+) T cells that recognized TRP-2 expressed by GL261 cells indicating that this melanoma-associated antigen may be suited for active immunotherapy of glioblastoma.

50 15781661 Furthermore, a 30-fold increase in the frequency of melanoma-associated antigen (Trp-2 and gp100) specific T cells was observed in mice treated with the combination when compared with unvaccinated controls.
51 15781661 These data show that IFN-alpha combined with a granulocyte macrophage colony-stimulating factor-secreting tumor cell vaccine significantly enhances vaccine potency and may represent a potential new approach for tumor immunotherapy.
52 15913853 Characterization of anti-self CD8 T-cell responses stimulated by recombinant Listeria monocytogenes expressing the melanoma antigen TRP-2.
53 15913853 We constructed a recombinant strain of Listeria monocytogenes (rLM) expressing murine tyrosinase-related protein-2 (TRP-2), a nonmutated melanocyte-derived differentiation antigen highly expressed in melanomas.
54 15913853 Immunization of C57Bl/6 mice with this rLM strain efficiently primed CD8 T cells to recognize the MHC class I-restricted TRP-2180-188 epitope and express IFN-gamma upon in vitro peptide stimulation.
55 16061687 To exploit these properties for immunization purposes, we conjugated the melanoma antigen tyrosinase-related protein (TRP)-2 to alphaDEC-205 antibodies and immunized mice with these conjugates together with dendritic cell-activating oligonucleotides (CpG).

61 16580737 Fusion protein of ATPase domain of Hsc70 with TRP2 acting as a tumor vaccine against B16 melanoma.
62 16699372 Using a peptide from the melanocyte differentiation antigen tyrosinase-related protein (TRP2) 2 we could show that vaccination with liposome-encapsulated peptide in combination with oligodeoxynucleotides containing unmethylated CpG motifs (CpG ODNs) as adjuvant leads to the induction of tumor cell-specific cytotoxic T cells.

90 17375074 We programmed mouse bone marrow (BM) cells with lentiviral vectors (LV-GI4) so that they produced granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in an autonomous manner.
91 17375074 The immunostimulatory efficacy of DC/LV-GI4 cells was evaluated using MART1 and TRP2 as co-expressed melanoma antigens.
92 18076066 In this article, we report that the melanocyte differentiation antigen TRP2 (tyrosinase-related protein 2) is not predominantly involved in the tumor rejection of a syngeneic murine glioma.
93 18680779 Co-delivery of cancer-associated antigen and Toll-like receptor 4 ligand in PLGA nanoparticles induces potent CD8+ T cell-mediated anti-tumor immunity.
94 18680779 Vaccination of mice bearing melanoma B16 tumors with PLGA nanoparticles (NP) co-encapsulating the poorly immunogenic melanoma antigen, tyrosinase-related protein 2 (TRP2), along with Toll-like receptor (TLR) ligand (7-acyl lipid A) was examined.
95 18680779 Activated TRP2-specific CD8 T cells were capable of interferon (IFN)-gamma secretion at lymph nodes and spleens of the vaccinated mice.
96 18807035 ABT-737, a small molecule inhibitor of the antiapoptotic proteins Bcl-2, Bcl-w and Bcl-x(L), was tested for the ability to increase antitumor immune responses in two tumor immunotherapy animal models.
97 18807035 However, the addition of ABT-737 to either a vaccine strategy involving priming with TRP-2 melanoma antigen peptide-pulsed DC and boosting with recombinant Listeria monocytogenes expressing the same melanoma antigen, or the adoptive transfer of TCR transgenic cells, did not result in superior antitumor activity against B16 murine melanoma.
98 18807035 In vitro studies failed to demonstrate increased cytotoxic lytic activity when testing the combination of ABT-737 with lymphokine activated killer (LAK) cells, or the death receptor agonists Fas, TRAIL-ligand or TNF-alpha against the CT26 and B16 cell lines.

103 19787240 By using electroporation-mediated gene/pDNA delivery, the anti-tumor efficacy of vaccination with pDNAs encoding gp100, TRP2 and Ii-PADRE was facilitated by administration of soluble form of EphB4 fused with human serum albumin (sEphB4-HSA), or by co-delivery of pDNAs encoding Angiostatin and/or Endostatin.
104 20937315 The adjuvant effects of the TLR7 agonist, imiquimod, and the TLR9 agonist, ODN1826, were tested with rAAV expressing the melanoma antigen, Trp2.
105 20937315 TLR7 and TLR9 agonists can be used to enhance the immune response to rAAV immunogens, but antagonism can be observed when combined.
106 21157438 Consequently, the cytosolic DNA sensor, DNA-dependent activator of interferon (IFN) regulatory factors (DAI), was used as a genetic adjuvant.
107 21157438 In vivo electroporation (EP) of mice with a DAI-encoding plasmid (pDAI) promoted transcription of genes encoding type I IFNs, proinflammatory cytokines, and costimulatory molecules.
108 21157438 Moreover, codelivery of pDAI effectively promoted CTL and CD4(+) Th1 responses to the TAA survivin.
109 21157438 The DAI-enhanced CTL induction required nuclear factor κB (NF-κB) activation and type I IFN signaling, but did not involve the IFN regulatory factor 3 (IRF3).
110 21157438 Codelivery of pDAI also increased CTL responses to the melanoma-associated antigen tyrosinase-related protein-2 (TRP2), enhanced tumor rejection and conferred long-term protection against B16 melanoma challenge.
111 21250746 Following immunization using US exposure and Man-PEG(2000) bubble lipoplexes constructed with pUb-M, which expresses ubiquitylated melanoma-specific antigens (gp100 and TRP-2), the secretion of Th1 cytokines (IFN-γ and TNF-α) and the activities of cytotoxic T lymphocytes (CTLs) were specifically enhanced in the presence of B16BL6 melanoma antigens.
112 21327126 Using an inducible and rapid expression plasmid, vaccination with several antigens of different length and epitope composition, including TRp-2, gp100 and MUC18, was evaluated against glioma tumor cells.
113 21327126 Characteristics that consistently improved anti-tumor immunity include: long peptides with immunodominant and cryptic CD8(+) epitopes, and strong CD4(+) Th epitopes.
114 21464590 Ex vivo assays using immunized mice demonstrated that CIITA-Exo induced a higher amount of Th1-polarized immune responses such as Th1-type IgG2a antibodies and IFN-γ cytokine as well as TRP2-specific CD8+ T cells.
115 21479379 Suppressor of cytokine signaling-1 (SOCS1) is a key negative regulator of the JAK/STAT signal pathway and plays an essential role in suppressing systemic autoimmunity that is mediated by DCs.
116 21479379 In the mouse melanoma model, we found that a 2x106 TRP2-pulsed DC vaccine was able to induce immune tolerance, while a 2x106 SOCS1-silenced DC/TRP2 vaccine prevented immune tolerance.
117 21479379 Further experiments revealed that activation-induced T cell death (AICD) through the Fas/Fas-L pathway may play a crucial role in immune tolerance induced by 2x106 TRP2-pulsed DC.
118 21479379 SOCS1-silencing in DCs could prevent immune tolerance by inhibiting Fas and Fas-L expression, induced by an increase in IL-12p70 and IL-6 production.
119 21479379 In addition, in 2x106 SOCS1-silenced DC/TRP2 immunized mice, higher levels of IL-12p70 and IFN-γ and lower IL-17 production may inhibit tumor angiogenesis and therefore assist in breaking immune tolerance.

123 21479379 SOCS1-silencing in DCs could prevent immune tolerance by inhibiting Fas and Fas-L expression, induced by an increase in IL-12p70 and IL-6 production.
124 21479379 In addition, in 2x106 SOCS1-silenced DC/TRP2 immunized mice, higher levels of IL-12p70 and IFN-γ and lower IL-17 production may inhibit tumor angiogenesis and therefore assist in breaking immune tolerance.
125 22120194 We reason that a strategy capable of improving CD8+ T cell activation would improve the efficacy of protein-based vaccines, which predominantly generate CD4+ T cell-mediated responses.
126 22120194 Herein, we explore the ability of a novel cell-penetrating peptide (CPP), LAH4, to facilitate intracellular delivery of protein-based vaccines adjuvanted with Toll-like receptor 9 agonist CpG oligonucleotide (CpG) to generate enhanced CD8+ T cell immune responses and antitumor effects.
127 22120194 Furthermore, we found that LAH4 was able to enhance the ability of a tyrosinase-related protein 2 (TRP-2) peptide-based vaccine to generate TRP2-specific CD8+ T cells and antitumor effects against TRP2-expressing tumors.
128 22506061 Similarly, the enlarged T cell repertoire in AIRE(-/-) mice enables them to mount anti-MAA and anti-melanoma responses as shown by increased anti-melanoma antibodies, and enhanced CD4(+) and MAA-specific CD8(+) T cell responses after melanoma challenge.
129 22506061 We show that thymic expression of gp100 is under the control of AIRE, leading to increased gp100-specific CD8(+) T cell frequencies in AIRE(-/-) mice.
130 22506061 TRP-2 (tyrosinase-related protein), on the other hand, is absent from TECs and consequently TRP-2 specific CD8(+) T cells were found in both AIRE(-/-) and AIRE(+/+) mice.
131 23104352 We describe here the use of particle-mediated gene transfer for the induction of immune responses against melanoma antigens in murine tumor models using the melanocyte differentiation antigen tyrosinase-related protein 2 (TRP2) as an antigen in a murine B16 melanoma model.
132 23333935 In situ Ad.Flagrp170 therapy provokes systemic activation of CTLs that recognize several antigens naturally expressing in melanoma (e.g., gp100/PMEL and TRP2/DCT).
133 23333935 Antibody neutralization assays show that IL-12 and IFN-γ are essential for the Flagrp170-elicited antitumor response, which also involves CD8(+) T cells and natural killer cells.
134 24018273 To try and understand why this is so, we have generated potent adenoviral vectors encoding the endogenous tumor Ags (TA) tyrosinase-related protein-2 (TRP-2) and glycoprotein 100 (GP100) tethered to the invariant chain (Ii).
135 24349329 To co-target CAFs and tumor cells we developed a new compound DC vaccine that encodes an A20-specific shRNA to enhance DC function, and targets fibroblast activation protein (FAP) expressed in CAFs and the tumor antigen tyrosine-related protein (TRP)2 (DC-shA20-FAP-TRP2).
136 24349329 DC-shA20-FAP-TRP2 vaccination induced robust FAP- and TRP2-specific T-cell responses, resulting in greater antitumor activity in the B16 melanoma model in comparison to monovalent vaccines or a vaccine encoding antigens and a control shRNA.
137 24795357 We have shown that a vaccine based on alphavirus replicon particles (VRP) activates strong cellular and humoral immunity to tyrosinase-related protein-2 (TRP2) melanoma antigen, providing prophylactic and therapeutic effects in stringent mouse models.
138 24795357 Here, we report that the immunogenicity and efficacy of this vaccine is increased in combination with either antagonist anti-CTL antigen-4 (CTLA-4) or agonist anti-glucocorticoid-induced TNF family-related gene (GITR) immunomodulatory monoclonal antibodies (mAb).
139 24795357 These mAbs had similar adjuvant effects in priming an adaptive immune response against the vaccine-encoded antigen, augmenting, respectively, approximately 4- and 2-fold the TRP2-specific CD8(+) T-cell response and circulating Abs, compared with the vaccine alone.
140 24795357 Furthermore, while both mAbs increased the frequency of tumor-infiltrating CD8(+) T cells, anti-CTLA-4 mAb also increased the quantity of intratumor CD4(+)Foxp3(-) T cells expressing the negative costimulatory molecule programmed death-1 (PD-1).
141 24795357 They also indicate that tumor-infiltrating CD4(+)Foxp3(-)PD-1(+) T cells may affect the outcome of immunomodulatory treatments.
142 24795357 We have shown that a vaccine based on alphavirus replicon particles (VRP) activates strong cellular and humoral immunity to tyrosinase-related protein-2 (TRP2) melanoma antigen, providing prophylactic and therapeutic effects in stringent mouse models.
143 24795357 Here, we report that the immunogenicity and efficacy of this vaccine is increased in combination with either antagonist anti-CTL antigen-4 (CTLA-4) or agonist anti-glucocorticoid-induced TNF family-related gene (GITR) immunomodulatory monoclonal antibodies (mAb).
144 24795357 These mAbs had similar adjuvant effects in priming an adaptive immune response against the vaccine-encoded antigen, augmenting, respectively, approximately 4- and 2-fold the TRP2-specific CD8(+) T-cell response and circulating Abs, compared with the vaccine alone.
145 24795357 Furthermore, while both mAbs increased the frequency of tumor-infiltrating CD8(+) T cells, anti-CTLA-4 mAb also increased the quantity of intratumor CD4(+)Foxp3(-) T cells expressing the negative costimulatory molecule programmed death-1 (PD-1).
146 24795357 They also indicate that tumor-infiltrating CD4(+)Foxp3(-)PD-1(+) T cells may affect the outcome of immunomodulatory treatments.
