We found no correlation between the expression levels of various PRRs (i.e., FPR1, TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR8, TLR9, TLR10, NOD1, NOD2, NALP1, NALP2, NALP3, RIG1, MDA5) and clinical features of NSCLC patients (data available on http://www.cbioportal.org (accessed on 4 January 2021)). The gene discussed is NOD2; the disease is non-small cell lung carcinoma.
