Organisational and methodological challenges of CAR-T manufacturing in the Russian Federation

Despite their widespread clinical implementation, chimeric antigen receptor T-cell (CAR-T) therapy products, including those manufactured by industrial processes, are still not legally available or used in the Russian Federation.The aim of the study was to describe the current challenges associated with specific aspects of CAR-T manufacturing in the Russian Federation and the potential ways to overcome them.This article discusses the regulatory, legal, organisational, and methodological challenges of CAR-T manufacturing. It analyses differences in the interpretation of CAR-T therapy products under national and supranational law. According to Russian Federal Law No. 180-FZ “On Biomedical Cell Products” of 23 June 2016, CAR-T therapy products are considered biomedical cell products. However, according to Decision No. 78 of the Council of the Eurasian Economic Commission “On the Rules of Marketing Authorisation and Assessment of Medicinal Products for Human Use” of 3 November 2016, CAR-T therapy products are considered advanced therapy medicinal products (ATMPs). This article provides a detailed overview of the difficulties in obtaining starting biological materials (i.e. the inability to consider the patient as a donor) and transferring the materials for CAR-T manufacturing (i.e. the inapplicability of national law). In addition, this article describes export aspects specific to biological materials. The authors reckon that CAR-T therapy products should be categorised as ATMPs and that the corresponding active pharmaceutical ingredients, genetically modified autologous lymphocytes, should be defined as starting materials. Therefore, genetically modified autologous lymphocytes should be regulated under the requirements for starting materials for the manufacturing of active pharmaceutical ingredients that are set forth in Decision No. 77 of the Council of the Eurasian Economic Commission “On the Adoption of the Rules of Good Manufacturing Practice of the Eurasian Economic Union” of 3 November 2016. In conclusion, the authors recognise the need for national and supranational law harmonisation. For this task, it is necessary to establish expert groups that will include clinicians, legal experts, and representatives from the relevant authorities and the pharmaceutical industry

Проанализированы расхождения в трактовке понятия CAR-T в национальном и наднациональном праве: как биомедицинского клеточного продукта согласно Федеральному закону от 23.06.2016 № 180-ФЗ «О биомедицинских клеточных продуктах» и как высокотехнологического лекарственного препарата (ВТЛП) согласно Решению Совета Евразийской экономической комиссии от 03.11.2016 № 78 «О Правилах регистрации и экспертизы лекарственных средств для медицинского применения». Подробно рассмотрены трудности на этапе получения исходного биологического материала (невозможность рассматривать пациента как донора биологического материала); на этапе передачи биологического материала для производства CAR-T (невозможность применения национального права); особенности экспорта биологического материала. По мнению авторов статьи, CAR-T следует относить к ВТЛП, активной фармацевтической субстанцией (АФС) которых являются генетически модифицированные аутологичные лимфоциты, а последние должны быть определены как «исходный материал», и к ним должны применяться требования как к исходному материалу для производства АФС, указанные в Решении Совета Евразийской экономической комиссии от 03.11.2016 № 77 «Об утверждении Правил надлежащей производственной практики Евразийского экономического союза». Сделано заключение о необходимости гармонизации национального и наднационального права, что требует формирования экспертных групп, объединяющих врачей-клиницистов, специалистов в области права, представителей профильных ведомств и фармацевтической индустрии

Lipolysis drives expression of the constitutively active receptor GPR3 to induce adipose thermogenesis

Thermogenic adipocytes possess a therapeutically appealing, energy-expending capacity, which is canonically cold-induced by ligand-dependent activation of β-adrenergic G protein-coupled receptors (GPCRs). Here, we uncover an alternate paradigm of GPCR-mediated adipose thermogenesis through the constitutively active receptor, GPR3. We show that the N terminus of GPR3 confers intrinsic signaling activity, resulting in continuous Gs-coupling and cAMP production without an exogenous ligand. Thus, transcriptional induction of Gpr3 represents the regulatory parallel to ligand-binding of conventional GPCRs. Consequently, increasing Gpr3 expression in thermogenic adipocytes is alone sufficient to drive energy expenditure and counteract metabolic disease in mice. Gpr3 transcription is cold-stimulated by a lipolytic signal, and dietary fat potentiates GPR3-dependent thermogenesis to amplify the response to caloric excess. Moreover, we find GPR3 to be an essential, adrenergic-independent regulator of human brown adipocytes. Taken together, our findings reveal a noncanonical mechanism of GPCR control and thermogenic activation through the lipolysis-induced expression of constitutively active GPR3

Relationship Between [18F]FDOPA PET Uptake, Apparent Diffusion Coefficient (ADC), and Proliferation Rate in Recurrent Malignant Gliomas

Purpose: Diffusion magnetic resonance imaging (MRI) and 6-[18F]fluoro-l-dopa ([18F]FDOPA) positron emission tomography (PET) are used to interrogate malignant tumor microenvironment. It remains unclear whether there is a relationship between [18F]FDOPA uptake, diffusion MRI estimates of apparent diffusion coefficient (ADC), and mitotic activity in the context of recurrent malignant gliomas, where the tumor may be confounded by the effects of therapy. The purpose of the current study is to determine whether there is a correlation between these imaging techniques and mitotic activity in malignant gliomas.Procedures: We retrospectively examined 29 patients with recurrent malignant gliomas who underwent structural MRI, diffusion MRI, and [18F]FDOPA PET prior to surgical resection. Qualitative associations were noted, and quantitative voxel-wise and median measurement correlations between [18F]FDOPA PET, ADC, and mitotic index were performed.Results: Areas of high [18F]FDOPA uptake exhibited low ADC and areas of hyperintensity T2/fluid-attenuated inversion recovery (FLAIR) with low [18F]FDOPA uptake exhibited high ADC. There was a significant inverse voxel-wise correlation between [18F]FDOPA and ADC for all patients. Median [18F]FDOPA uptake and median ADC also showed a significant inverse correlation. Median [18F]FDOPA uptake was positively correlated, and median ADC was inversely correlated with mitotic index from resected tumor tissue.Conclusions: A significant association may exist between [18F]FDOPA uptake, diffusion MRI, and mitotic activity in recurrent malignant gliomas

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

Peculiarities of the technogenical radionuclides transfer from soils into plants in the radioactive contaminated areas

The peculiarities of 90Sr, 137Cs, 239,240Pu accumulation by some species of herbaceous plants in radioactive contaminated areas of nuclear enterprises in Russia have been investigated. Gas and aerosol discharge from Beloyarskaya NPP (which operates for more than 30 years) did not make considerable contamination of soil-vegetational cover in the 30-km zone. In close proximity to the epicenter of nuclear accident of 1957 in the Urals the concentration of the main contaminant (90Sr) in the plants reached maximal value (tens and hundred of thousands of Bq kgdw-1 depending on species belonging of plant). The concentration of 90Sr in aboveground phytomass of plants growing within floodplain of the Techa river ecosystems is thousands of Bq kgdw-1; at the same time, the 137Cs concentration is units of Bq kgdw-1. The absence of direct dependence between the radionuclides content in the soils and their concentration in aboveground phytomass is noticeable. The values of the radionuclides transfer coefficients in the plants were estimated as well as the content in the soils of their water-soluble and firmly fixed physic-chemical forms. The radionuclides have been ranked into a row according to their mobility in observed soils and biogeocenotical soil-plant link
