TLR3 and myasthenia gravis: We also observed that in EBV-positive MG thymomas TLR3 mRNA levels positively correlated with those of EBER1 (Spearman test, r=0.75; p<0.01, Figure 6A), suggesting a role for this viral small RNA molecule in stimulating TLR3 signaling and a contribution of TLR3 in MG associated with thymoma.
