Collagen Type II and a Thermo-Responsive Polymer of N-Isopropylacrylamide Induce Arthritis Independent of Toll-Like Receptors A Strong Influence by Major Histocompatibility Complex Class II and Ncf1 Genes
We established and characterized an arthritis mouse model using collagen type II (CH) and a thermo-responsive polymer, poly(N-isopropylacrylamide) (PNiPAAm). The new PNiPAAm adjuvant is TLR-independent, as all immunized TLR including MyD88-deficient mice developed an anti-CII response. Unlike other adjuvants, PNiPPAm did not skew the cytokine response (IL-1 beta, IFN-gamma, IL-4, and IL-17), as th
