Expression of helicase DDX41 in human dental pulp tissues and cells / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To detect the expression of D-E-A-D-box polypeptide 41 (DDX41) in human dental pulp tissues and cells.</p><p><b>METHODS</b>The mRNA and protein expressions of DDX41 in human dental pulp cells were detected by RT-PCR and immunocytochemistry, and the expression of DDX41 in human dental pulp tissues was investigated by immunohistochemistry.</p><p><b>RESULTS</b>Strong expressions of DDX41 mRNA and protein were detected in dental pulp cells. In dental pulp tissues, DDX41 was expressed in the cytoplasm and nucleus of odontoblasts.</p><p><b>CONCLUSION</b>DDX41/STING-dependent TBK1-IRF3-IFN-β signaling pathway may play a role in innate immune responses of the dental pulp to caries and pulpitis.</p>
