Tumor-Associated Senescent Macrophages, Their Markers, and Their Role in Tumor Microenvironment.

Tumor-associated macrophages (TAMs) are an important component of the tumor microenvironment (TME) and the most abundant population of immune cells infiltrating a tumor. TAMs can largely determine direction of anti-tumor immune response by promoting it or, conversely, contribute to formation of an immunosuppressive TME that allows tumors to evade immune control. Through interactions with tumor cells or other cells in the microenvironment and, as a result of action of anti-cancer therapy, macrophages can enter senescence.

Emerging Roles of Vitamin B in Aging and Inflammation.

Vitamin B (cobalamin) is an essential nutrient for humans and animals. Metabolically active forms of B-methylcobalamin and 5-deoxyadenosylcobalamin are cofactors for the enzymes methionine synthase and mitochondrial methylmalonyl-CoA mutase. Malfunction of these enzymes due to a scarcity of vitamin B leads to disturbance of one-carbon metabolism and impaired mitochondrial function.

The Differential Effect of Senolytics on SASP Cytokine Secretion and Regulation of EMT by CAFs.

The tumor microenvironment (TME) plays an essential role in tumor progression and in modulating tumor response to anticancer therapy. Cellular senescence leads to a switch in the cell secretome, characterized by the senescence-associated secretory phenotype (SASP), which may regulate tumorigenesis. Senolytic therapy is considered a novel anticancer strategy that eliminates the deleterious effects of senescent cells in the TME.

Reliable Hallmarks and Biomarkers of Senescent Lymphocytes.

The phenomenon of accumulation of senescent adaptive immunity cells in the elderly is attracting attention due to the increasing risk of global epidemics and aging of the global population. Elderly people are predisposed to various infectious and age-related diseases and are at higher risk of vaccination failure. The accumulation of senescent cells increases age-related background inflammation, "Inflammaging", causing lymphocyte exhaustion and cardiovascular, neurodegenerative, autoimmune and cancer diseases.

[A model for assessing and correcting the risk of developing pressure ulcers in the system of long-term care for geriatric patients with limited mobility.].

The article is devoted to the results of the third stage of the scientific and practical project on the introduction of advanced social practices based on innovative gerontotechnologies into the system of long-term care for geriatric patients. It has been established that senile xerosis or skin «frailty» occurs in 75% of the population over 65 years old, when increased dryness of the skin leads to peeling, the formation of microcracks, the appearance of senile itching, sleep disturbances, the development of pressure ulcers and, as a result, a decrease in motor activity. During the project, a tactic was developed for the care of «frail» skin in patients with senile xerosis and the risk of pressure ulcers.

Potential Binding Sites of Pharmacological Chaperone NCGC00241607 on Mutant β-Glucocerebrosidase and Its Efficacy on Patient-Derived Cell Cultures in Gaucher and Parkinson's Disease.

Mutations in the gene, encoding the lysosomal enzyme glucocerebrosidase (GCase), cause Gaucher disease (GD) and are the most common genetic risk factor for Parkinson's disease (PD). Pharmacological chaperones (PCs) are being developed as an alternative treatment approach for GD and PD. To date, NCGC00241607 (NCGC607) is one of the most promising PCs.

Thermodynamic Signatures of Blood Plasma Proteome in Neurodegenerative Pathologies.

Discovery of diagnostic biomarkers for age-related neurodegenerative pathologies (NDDs) is essential for accurate diagnosis, following disease progression and drug development. Blood plasma and blood cells are important peripheral sources for NDDs' biomarkers that, although present in lower concentrations than in cerebrospinal fluid, would allow noninvasive diagnostics. To identify new biomarkers for Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS), in this work we have evaluated the modifications in the thermodynamic behavior of blood plasma proteome exploring differential scanning calorimetry.

Two clinical case reports of embryonic mosaicism identified with PGT-A persisting during pregnancy as true fetal mosaicism.

The health risks associated with transferring embryos classified as mosaic by preimplantation genetic testing for aneuploidies (PGT-A) are currently unknown. Such embryos produce PGT-A results indicating the presence of both euploid and aneuploid cells and have historically been deselected from transfer and grouped with uniformly aneuploid embryos as 'abnormal'. In recent years, numerous groups have reported the intentional transfer of mosaic embryos in the absence of uniformly euploid embryos, largely observing births of seemingly healthy babies.

[Quality of life and physical activity among elderly and old people.].

This article presents the results of the identification of the main causes of physical inactivity among the elderly and the assessment of the effectiveness of the inclusion of regular Nordic walking into the preventive system for the elderly in order to improve the quality of life. A comparative analysis of the quality of life was used among elderly and old people, regularly engaged in Nordic walking (intervention group) and leading a physically passive lifestyle (control group). It was established that regular physical activity allows the improvement of the quality of life and positively affects health in groups under study, but it is the elderly people who represent the most physically inactive part of the population.

Essential Role of Canonical NF-κB Activity in the Development of Stromal Cell Subsets in Secondary Lymphoid Organs.

Organized tissue structure in the secondary lymphoid organs (SLOs) tightly depends on the development of fibroblastic stromal cells (FSCs) of mesenchymal origin; however, the mechanisms of this relationship are poorly understood. In this study, we specifically inactivated the canonical NF-κB pathway in FSCs in vivo by conditionally inducing IκBα mutant in a mouse system in which NF-κB activity is likely to be suppressed in fetal FSC progenitors. Given that NF-κB activation in fetal FSCs is essential for SLO development, the animals were expected to lack SLOs.

Visualizing the Rapid and Dynamic Elimination of Allogeneic T Cells in Secondary Lymphoid Organs.
