Hematopoietic stem cell transplantation (HSCT) is a standard method for treating a number of pathologies, primarily blood diseases. Timely restoration of the immune system after HSCT is a critical factor associated with the development of complications such as relapses or secondary tumors and various infections, as well as the graft-versus-host reaction in allogeneic transplantation, which ultimately affects the survival of patients. Introduction into the recipient's body of immune system cells that are incapable of sensitization by recipient antigens during the period of immune reconstitution can increase the rate of restoration of the immune system, as well as reduce the risk of complications.

Progression of acute traumatic brain injury (TBI) into chronic neurodegeneration is a major health problem with no protective treatments. Here, we report that acutely elevated mitochondrial fission after TBI in mice triggers chronic neurodegeneration persisting 17 months later, equivalent to many human decades. We show that increased mitochondrial fission after mouse TBI is related to increased brain levels of mitochondrial fission 1 protein (Fis1) and that brain Fis1 is also elevated in human TBI.

The article summarizes the results of our own scientific and practical research on biopuncture (or pharmacopuncture) - local stimulation of acupuncture points with small doses of drugs or other agents. The "object" of the work was dorsopathies at the lumbosacral level, the choice of which was explained by the widest coverage of the population, the protracted course and the severity of the consequences. In the course of the research, the addition and even potentiation of the reflex and drug links of the method under consideration was noted.

Article Synopsis
  • The research identifies the role of gut microbial metabolites in Alzheimer's disease (AD) and focuses on the host's G-protein-coupled receptors (GPCRs) that interact with these metabolites.
  • Using a systems biology framework, the study analyzes 1.09 million metabolite-protein pairs, revealing orphan GPCRs like GPR84 as potential drug targets.
  • The findings show that specific metabolites, such as phenethylamine and agmatine, can reduce tau hyperphosphorylation in neurons linked to AD, highlighting a novel approach to exploring GPCR targets in complex diseases.

In adult fish, neurogenesis occurs in many areas of the brain, including the cerebellum, with the ratio of newly formed cells relative to the total number of brain cells being several orders of magnitude greater than in mammals. Our study aimed to compare the expressions of aromatase B (AroB), glutamine synthetase (GS), and cystathionine-beta-synthase (CBS) in the cerebellum of intact juvenile chum salmon, . To identify the dynamics that determine the involvement of AroB, GS, and CBS in the cellular mechanisms of regeneration, we performed a comprehensive assessment of the expressions of these molecular markers during a long-term primary traumatic brain injury (TBI) and after a repeated acute TBI to the cerebellum of juveniles.
