Peptide nanofibers efficiently delivered CD8+ T cell epitopes to APCs and stimulated CD8+ T cell responses. (a)
Representative flow cytometry data showing SIINFEKL/MHC-I positive dendritic cells 20 h after i.p. injections of SIINFEKL/Alum,
SIINFEKL-Coil29, or SIINFEKL-Q11 (b) Quantification of SIINFEKL presentation in MHC-I by DCs. SIINFEKL-Coil29 immunization led to
a significantly larger proportion of SIINFEKL-presenting DCs compared with SIINFEKL-Q11 and SIINFEKL/Alum (N=3 mice per group,
p<0.05, analyzed by two-way ANOVA for multiple comparison.) (c) Splenocytes harvested from mice immunized with
SIINFEKL/CFA, SIINFEKL-Coil29, or SIINFEKL-Q11 exhibited comparable IFNγ responses when restimulated with SIINFEKL peptide.
(# statistically insignificant, N=12 mice per group, analyzed by two-way ANOVA for multiple comparison.)
