Paper Development of an Efficient Transdermal Delivery System of Small Interfering RNA Using Functional Pe
Peptide Tat analog + AT1002 analog (AT-1002)
Delivery Success Class no
In Vivo Flag yes
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration Tat 32 µg + AT1002 400 µg per application
Rna Concentration 5 µg fluorescent siRNA per application; 10 h
Mixing Ratio Tat/siRNA N/P = 10 + AT1002 400 µg (TatAT1002 condition)
Formulation Format Topical Tat/siRNA complex + AT1002 co-formulation for transdermal delivery
Formulation Components Tat/siRNA complexes mixed with AT1002 and applied to tape-stripped mouse skin
Size Nm 70.00
Zeta Mv 4.00
Model Scope in_vivo
Model Type in vivo
Cell Lines Or Primary Cells
Animal Model ICR mice (male, 6-week); back skin tape-stripped; topical 10 h
Administration Route Topical application to tape-stripped dorsal skin (25 µL); confocal imaging
Output Type In vivo uptake/distribution in skin (confocal microscopy)
Output Value Strongest and widest siRNA localization (hair follicles + epidermal/dermal layers), higher brightness vs Tat or AT1002 alone
Output Units
Output Notes Combination improves both RNase stability and transdermal penetration depth/coverage.
