Small RNAs of Mycobacterium tuberculosis Regulate Pathogen Virulence and Host Immune Responses
A team of researchers from the Shemyakin–Ovchinnikov Institute of Bioorganic Chemistry of the Russian Academy of Sciences, together with colleagues from the Bach Institute of Biochemistry of the Research Center of Biotechnology of the Russian Academy of Sciences and the Central Tuberculosis Research Institute, conducted a comprehensive study of the roles of the small RNAs MTS1338 and MTS0997 in tuberculosis pathogenesis. The findings demonstrated that these molecules contribute to the regulation of M. tuberculosis metabolism and virulence and can also modulate the host immune response. Thus, MTS1338 and MTS0997 may be regarded as factors coordinating mycobacterial interactions with the host organism and as potential targets for developing new approaches to antituberculosis therapy. This work was supported by Russian Science Foundation Grant No. 22-14-00235 and published in Frontiers in Cellular and Infection Microbiology. Learn more

- Dual-Color Bioluminescent Reporters Enable Quantitative Measurement of Gene Expression Independent of Metabolic Fluctuations
science news
X.29 A study by an international team of scientists led by researchers from the Shemyakin–Ovchinnikov Institute of Bioorganic Chemistry of the Russian Academy of Sciences (IBCh RAS) has been published in Nature Plants. The study presents and validates a simple and elegant approach to making autonomous bioluminescent reporters resistant to metabolic fluctuations. The researchers developed pairs of luciferases that use the same substrate but emit light of different colors and demonstrated that the ratio between the two signals reflects reporter gene activity rather than the metabolic state of the cell. This approach enables long- term monitoring of plant hormone signaling and defense responses.
- Small RNAs of Mycobacterium tuberculosis Regulate Pathogen Virulence and Host Immune Responses
science news
X.27 Mycobacterium tuberculosis, the causative agent of tuberculosis, determines the severity of infection not only through virulent proteins but also through small regulatory RNAs. Researchers from the Shemyakin–Ovchinnikov Institute of Bioorganic Chemistry of the Russian Academy of Sciences, together with colleagues from the Bach Institute of Biochemistry of the Research Center of Biotechnology of the Russian Academy of Sciences and the Central Tuberculosis Research Institute, studied two such molecules, MTS0997 and MTS1338, and showed that they simultaneously affect pathogen properties and shape the host immune response.
