Peptide P60
Based on 1 publication(s) in Google Scholar
Peptide P60 is a FOXP3 inhibitor. Peptide P60 reduces the nuclear translocation of FOXP3 and impairs FOXP3-mediated inhibition of NF-κB and NFAT activity. Peptide P60 inhibits the immunosuppressive activity of regulatory T cells and restores the proliferation and activation of effector T cells. Peptide P60 induces lymphoproliferative autoimmune syndrome in neonatal ICR mice and reduces the number of CD4+CD25+Foxp3+ T cells in the spleen. Peptide P60 enhances the efficacy of AH1 (HY-P4193) peptide vaccine and recombinant adenovirus-based HCV NS3 vaccine in BALB/c mice, including protective effects against CT26 tumor implantation. Peptide P60 can be used in studies related to tumor immunity, viral infection and lymphoproliferative autoimmune syndrome.

FOXP3 |
Peptide P60 (5 μM; 60 s association, 30 s dissociation) specifically binds to recombinant human FOXP3 protein in cell-free surface plasmon resonance assays[1].
Peptide P60 (10 μM; 2-18 min) can enter live Jurkat T cells, with its intracellular accumulation detectable within 2 min and reaching a peak at 10 min of incubation[1].
Peptide P60 (100 μM; 24 h) inhibits the nuclear translocation of transiently transfected FOXP3 in human embryonic kidney 293 cells, partially restores the NF-κB transcriptional activity suppressed by FOXP3 overexpression in human embryonic kidney 293 cells, and rescues the NFAT transcriptional activity inhibited by FOXP3 overexpression in Jurkat T cells[1].
Peptide P60 (100 μM; 3 days) inhibits the suppressive function of murine or human CD4+CD25+ regulatory T cells (Tregs), restores the proliferation of CD4+CD25− effector T cells from BALB/c mice stimulated with anti-CD3 antibody, and restores the proliferation of human peripheral blood mononuclear cells (PBMCs) stimulated with anti-CD3/CD28 magnetic beads[1].
Peptide P60 (100 μM; 3 days) inhibits the suppressive function of mouse or human CD4+CD25+ Treg cells, restores the proliferation of BALB/c mouse effector T cells in mixed lymphocyte reactions with C57BL/6 dendritic cells, and restores the proliferation of human peripheral blood mononuclear cells (PBMCs) in mixed lymphocyte reactions[1].
Peptide P60 (100 μM; 48 h) modulates gene expression in human CD4+CD25− effector T cells stimulated by anti-CD3, reduces the mRNA levels of Foxp3 and IL-10, and increases the mRNA level of IFN-γ[1].
Peptide P60 (100 μM; 48 h) upregulates IL-2 mRNA expression in human CD4+CD25+ regulatory T cells (Tregs) stimulated with IL-2 + anti-CD3, without altering the mRNA levels of Foxp3 or IFN-γ[1].

-
Cell Line:Jurkat T cells
-
Concentration:10 μM
-
Incubation Time:2, 4, 6, 8, 10, 14, 18 min
-
Result:Increased intracellular mean fluorescence intensity significantly over time, reaching a peak at 10 min and remaining elevated through 18 min.
Showed no significant increase in intracellular mean fluorescence intensity with the control peptide.
-
Cell Line:Human embryonic kidney 293 cells (transiently transfected with FOXP3-enhanced GFP fusion protein)
-
Concentration:100 μM
-
Incubation Time:24 h
-
Result:Reduced nuclear localization of FOXP3-EGFP significantly, shifting fluorescence to the cytoplasmic compartment.
Caused no change in nuclear localization with the control peptide, and FOXP3-EGFP expression levels were equivalent across groups.
When administered in combination with the AH1 peptide vaccine, Peptide P60 (50 nM/mouse; i.p.; daily; days 0-9 post immunization) increases the tumor-free survival rate of BALB/c mice challenged with CT26 colorectal cancer cells to 82%[1].
When administered in combination with the RAdNS3 vaccine, Peptide P60 (50 nM/mouse; i.p.; daily; days 0-10 after immunization) provides complete protection against recombinant vaccinia virus HCV challenge in BALB/c mice[1].
