The Toll like Receptor (TLR) family plays an essential role in pathogen recognition and innate immunity activation. TLR8, an endosomal receptor, can recognize single-stranded RNA viruses, such as influenza virus, Sendai virus, Coxsackie B virus, HIV, and HCV. TLR8 binding to the viral RNA recruits MyD88 and leads to activation of the transcription factor NF-kB and antiviral response. We generated biallelic mutants of the TLR8 gene using a CRISPR-Cas9 genome editing method in human induced pluripotent stem cells (hiPSCs). The TLR8 homozygous-knockout hiPSCs retained normal morphology, gene expression, and in vivo differentiation potential.
