mTRP-2 (180-188)
Based on 1 Customer Validation
mTRP-2 (180-188) is an MHC class I-restricted tumor-associated antigenic peptide derived from mouse tyrosinase-related protein 2 (TRP-2). mTRP-2 (180-188) binds to HLA-A*0201 with an ID50 of 36 nM. mTRP-2 (180-188) can be presented by H-2Kb molecules and activate TRP-2-specific cytotoxic T lymphocytes (CTL). mTRP-2 (180-188) induces immune responses against B16 melanoma by promoting antigen-specific T cell proliferation, cytokine release, and CTL-mediated tumor cell killing. mTRP-2 (180-188) can be used in studies related to melanoma, glioma, and tumor immunology.

In Vitro
mTRP-2 (180-188) (5 μg/mL) stimulates mouse splenocytes to generate TRP-2-specific CTLs, and the generated CTLs recognize B16 melanoma cells and exert antigen-specific cytotoxic effects[1].
mTRP-2 (180-188) induces the generation of CTLs from HLA-A0201-positive melanoma samples, and these CTLs specifically recognize peptide-loaded T2 cells, COS-7 cells expressing HLA-A0201/TRP-2, as well as HLA-A2-positive and TRP-2-positive melanoma cells[2].
mTRP-2 (180-188) (1 μM; 5 days) stimulates TRP-2-specific TCR transgenic lymphocytes in the presence of IL-2 and generates CD8+ T cell effector cells with potent antigen-specific cytotoxic activity[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Dendritic cell vaccine loaded with mTRP-2 (180-188) induces CTL-mediated protective immune responses in C57BL/6 mice and inhibits the growth of subcutaneous B16 melanoma[3].
mTRP-2 (180-188) (1 μM; 5 days) generates TRP-2-specific CD8+ T cell effector cells in vitro. Repeated intravenous transfer of these cells reduces B16 lung tumor nodules, but does not significantly inhibit the growth of subcutaneous B16 tumors[5].

Animal Model:C57BL/6 (H-2b) (male, 8-12 weeks of age, melanoma model via s.c. challenge with 1×105 live B16F10 melanoma cells)[3]
-
Dosage:mTRP-2 (180-188): 25 μM for DC loading; DCs: 4 × 105

Result:Induced high-avidity TRP-2-specific CTLs and provided approximately 80% protection against subsequent B16 melanoma challenge.
-
Animal Model:C57BL/6 (female, 6-12 weeks old, intravenous injection of 2×105 B16/BL6 melanoma cells to induce pulmonary tumor nodules)[5]
-
Dosage:mTRP-2 (180-188): 1 μM during ex vivo T-cell activation; TRP-2-specific effector cells: 1 × 107/mouse
-
Administration:i.v.; 3 doses on days 3, 7, 11 after tumor challenge
-
Result:Significantly reduced the number of pulmonary B16 tumor nodules compared to control groups.
Significantly reduced lung weight compared to control groups.
-
Animal Model:C57BL/6 (female, 6-12 weeks old, subcutaneous injection of 1×105 B16/BL6 melanoma cells)[5]
-
Dosage:5×106 TRP-2(180-188)-specific TCR transgenic lymph node cells; 2.5×105 TRP-2(180-188)-pulsed bone marrow-derived dendritic cells per dorsal flank
-
Administration:i.v. (lymph node cells); s.c. (dendritic cells)
-
Result:Did not reduce subcutaneous B16 tumor growth compared to control-vaccinated or untransferred mice.
Maintained high CD44 expression, granzyme B expression, and IFN-γ production with only modest, statistically significant reductions in IFN-γ at later time points.
Maintained high CD107a mobilization with only modest, statistically significant reductions in CD107a at later time points.
