IFNB1 and infection: Our data showed that transcription of the IFI204, IFNβ, STING, gene was induced via infection of only 3 strains, two strains of MAB-R [S-Abs_R (M. abscessus type strain ATCC 19977 rough strain), and S-Mas_II-R (Asan 50594)] and M. marinum, and not by infection of other mycobacterial strains ([S-Abs_S (M. abscessus type strain ATCC 19977 smooth strain) and S-Mas_I-S (Asan 51843)] and M. bovis BCG), further proving the enhanced Type I IFN signaling by MAB-R strains.
