Scientists from IBCH RAS and their colleagues propose a way to tell reliable immune recognition data from faulty records
T cells spot infected and tumour cells by the molecular tags on their surface, and knowing which receptor fits which tag underpins cellular cancer therapies and a new generation of vaccines. A recent independent screen confirmed only about half of the entries in the world’s databases of these matches. Scientists from IBCH RAS and their colleagues have shown how to separate the sound records from the faulty ones: the statistical filter they propose isolates a core of entries that validate experimentally in 81% of cases, against 38% for the rest. Many apparent failures turned out to be annotation errors, not absent recognition. The work is published in Nature Methods. 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.

science news
X.15 A photograph of the bioluminescent fungus Neonothopanus nambi, featured in a paper by researchers from the Department of Biomolecular Chemistry, was selected for the cover of the October issue of The FEBS Journal (Volume 293, Issue 20, 2026). The paper also ranked among the top five most-read articles published in The FEBS Journal over the past six months.
