Abstract
Bacterial infections represent an unsolved problem today since bacteria can evade antibiotics and suppress the host's immune response. A family of TRIM proteins is known to play a role in antiviral defense. However, the data on the involvement of the corresponding genes in the antibacterial response are limited. Here, we used RT-qPCR to profile the transcript levels of TRIM genes, as well as interferons and inflammatory genes, in human cell lines (in vitro) and in mice (in vivo) after bacterial infections caused by Pseudomonas aeruginosa and Chlamydia spp. As a result, the genes were identified that are involved in the overall immune response and associated primarily with inflammation in human cells and in mouse organs when infected with both pathogens (TRIM7, 8, 14, 16, 17, 18, 19, 20, 21, 47, 68). TRIMs specific to the infection (TRIM59 for P. aeruginosa, TRIM67 for Chlamydia spp.) were revealed. Our findings can serve as a basis for further, more detailed studies on the mechanisms of the immune response to P. aeruginosa and Chlamydia spp. Studying the interaction between bacterial pathogens and the immune system contributes to the search for new ways to successfully fight bacterial infections.
