## Education and career

Chudakov studied molecular biology at Lomonosov Moscow State University, taking a B.S. in 1998 and an M.Sc. in 2000.<sup>[2](https://www.ibch.ru/lgr/cv/cv_chu.htm)</sup> From 2000 he worked at IBCh RAS, first as a postgraduate student in the Laboratory of Genes for Regeneration, and defended his Ph.D. thesis, "Photo-conversion of Anthozoa chromoproteins," in 2003 under K.A. Lukyanov.<sup>[1](https://www.ibch.ru/en/unit/gocs/45)</sup><sup> • </sup><sup>[2](https://www.ibch.ru/lgr/cv/cv_chu.htm)</sup> According to his 2011 Doctor of Biological Sciences dissertation abstract, "Genetically encoded fluorescent instruments for the studies of living systems," from 2003 he was a research scientist in the Laboratory of Molecular Technologies headed by S.A. Lukyanov, and the dissertation was written there under Sergey A. Lukyanov.<sup>[2](https://www.ibch.ru/lgr/cv/cv_chu.htm)</sup><sup> • </sup><sup>[7](https://www.studmed.ru/chudakov-d-m-geneticheski-kodiruemye-fluorescentnye-instrumenty-dlya-issledovaniya-zhivyh-sistem_3b4f4ef785b.html)</sup> 

His later appointments are dated on his institutional record: Head of the Department of Genomics of Adaptive Immunity at IBCh RAS from 2017; and Head of the Adaptive Immunity research group at CEITEC (Central European Institute of Technology, Brno) from 2013.<sup>[1](https://www.ibch.ru/en/unit/gocs/45)</sup> At RNIMU he became director of the Institute of Translational Medicine and head of the department of molecular technologies; his staff profile lists the directorship as acting.<sup>[3](https://rsmu.ru/website-information/profil-sotrudnika?cHash=e6748c3eb9f9a4655d311439c559bea7&cv=7304&cvview=105)</sup><sup> • </sup><sup>[8](https://rsmu.ru/index.php?id=3691)</sup> A funder record also lists a professorship at Skoltech, without dates.<sup>[9](https://megagrant.ru/labs/scientists/scientist_rus_531361/)</sup>

## Fluorescent protein tools

Chudakov's first research line engineered fluorescent proteins for labeling molecules in living cells. His group developed a palette of bright monomeric proteins spanning the visible spectrum, TagBFP, TagCFP, TagGFP, TagYFP, and TagRFP, together with the far-red mKate and mKate2; TagRFP was reported as the brightest monomeric red fluorescent protein and mKate2 the brightness leader among monomeric far-red proteins.<sup>[3](https://rsmu.ru/website-information/profil-sotrudnika?cHash=e6748c3eb9f9a4655d311439c559bea7&cv=7304&cvview=105)</sup> The same line produced the fast-maturing TurboGFP, TurboYFP, TurboRFP, and TurboFP602, and the far-red Katushka (TurboFP635), whose long-wavelength emission improves detection of cells inside living tissue.<sup>[3](https://rsmu.ru/website-information/profil-sotrudnika?cHash=e6748c3eb9f9a4655d311439c559bea7&cv=7304&cvview=105)</sup> He also worked out the mechanism of reversible photoactivation of fluorescence, based on cis-trans isomerization of the chromophore, and used it to build high-contrast photoactivatable proteins suitable for super-resolution microscopy; the dissertation additionally credits his participation in KillerRed, a genetically encoded photosensitizer.<sup>[3](https://rsmu.ru/website-information/profil-sotrudnika?cHash=e6748c3eb9f9a4655d311439c559bea7&cv=7304&cvview=105)</sup><sup> • </sup><sup>[7](https://www.studmed.ru/chudakov-d-m-geneticheski-kodiruemye-fluorescentnye-instrumenty-dlya-issledovaniya-zhivyh-sistem_3b4f4ef785b.html)</sup>

## Immune repertoire profiling: MiXCR

From 2009 Chudakov moved to high-throughput sequencing of T cell receptor and antibody repertoires, applying molecular barcoding to TCR repertoire analysis for the first time, a step that improved measurement accuracy by an order of magnitude.<sup>[9](https://megagrant.ru/labs/scientists/scientist_rus_531361/)</sup> The group's MiXCR software, published in *Nature Methods* in 2015, analyzes next-generation sequencing data for immune profiling: it handles bulk [repertoire sequencing](https://www.edgepedia.org/repertoire-sequencing) with or without unique molecular identifiers, single-cell data including 10x Genomics protocols, and RNA-seq or fragmented data containing TCR or BCR sequences.<sup>[4](https://github.com/milaboratory/mixcr)</sup> In 2024 a MiXCR-based study established a database of V and J gene alleles inferred from repertoire sequencing data, with population frequencies and free public access through VDJ.online.<sup>[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC11694755/)</sup>

## TRBV9+ T cell depletion immunotherapy

The clinical line of this work asks whether a defined pathogenic T cell population can be removed to treat autoimmune disease. In a 2023 *Nature Medicine* case study, an HLA-B*27-positive patient with ankylosing spondylitis achieved remission within three months of depletion of TRBV9+ T cells and stopped anti-TNF therapy after five years of continuous use; complete remission persisted for four years on three doses of anti-TRBV9 antibody per year.<sup>[5](https://www.nature.com/articles/s41591-023-02613-z)</sup> When some symptoms partially returned ten months after the first intervention, the pathogenic TCRβ CDR3 motif re-emerged among peripheral blood T cells, supporting its causative role in the disease.<sup>[5](https://www.nature.com/articles/s41591-023-02613-z)</sup> The anti-TRBV9 therapy entered a phase II trial for ankylosing spondylitis (NCT05445076).<sup>[5](https://www.nature.com/articles/s41591-023-02613-z)</sup> The RNIMU project describes the approach, sectoral suppression of T cell immunity by identifying and removing disease-causing cells, as having produced the first-in-class drug Tribuvia for ankylosing spondylitis with the industrial partner Biocad, and lists planned drugs for juvenile arthritis, uveitis and type 1 diabetes, a diagnostic system for adaptive immune status, and Treg-TCR-T therapy using autologous regulatory T lymphocytes.<sup>[8](https://rsmu.ru/index.php?id=3691)</sup> The *Nature Medicine* authors note the approach could extend to other HLA-B*27-associated spondyloarthropathies, including psoriatic arthritis, acute anterior uveitis, juvenile idiopathic arthritis, and [Crohn's disease](https://www.edgepedia.org/crohns-disease).<sup>[5](https://www.nature.com/articles/s41591-023-02613-z)</sup>

## Honors and recognition

The Presidential Prizes in Science and Innovation for Young Scientists for 2012 were presented on February 8, 2013, with Chudakov among about four laureates; his prize was awarded for the development of genetically encoded fluorescent markers for visualization of objects and processes in biomedical research.<sup>[6](http://kremlin.ru/events/president/news/17459)</sup> His IBCh record names him Professor of the Russian Academy of Sciences in Biology in 2016 and a Corresponding Member of the Academy from 2022.<sup>[1](https://www.ibch.ru/en/unit/gocs/45)</sup> A funder record adds membership of the Grants Council of the President of the Russian Federation since 2015 and of the Ministry of Education and Science Science Council, 2013 to 2015.<sup>[9](https://megagrant.ru/labs/scientists/scientist_rus_531361/)</sup>

## Representative work

His TRBV9 depletion study, "Targeted depletion of TRBV9+ T cells as immunotherapy in a patient with ankylosing spondylitis," *Nature Medicine*, 2023, reported that an HLA-B*27-positive patient achieved remission within three months of TRBV9+ T cell depletion, with complete remission persisting for four years ([doi:10.1038/s41591-023-02613-z](https://doi.org/10.1038/s41591-023-02613-z)).<sup>[5](https://www.nature.com/articles/s41591-023-02613-z)</sup>

## Recent developments

According to Dmitriy Chudakov's official IBCh RAS profile, since the *Nature Medicine* paper the anti-TRBV9 therapy has moved into a phase II trial and the Tribuvia drug has been developed with Biocad, while, per his profile, the MiXCR line has added a 2024 allele-inference database distributed through VDJ.online.<sup>[5](https://www.nature.com/articles/s41591-023-02613-z)</sup><sup> • </sup><sup>[8](https://rsmu.ru/index.php?id=3691)</sup><sup> • </sup><sup>[10](https://pmc.ncbi.nlm.nih.gov/articles/PMC11694755/)</sup> His IBCh record adds a Professor appointment in the Department of Postgraduate Studies from 2026, and his stated current research focus is clonal T cell and [B cell](https://www.edgepedia.org/b-cell) populations in autoimmunity and cancer and quantitative analysis of T cell receptor and antibody repertoires.<sup>[1](https://www.ibch.ru/en/unit/gocs/45)</sup>
