Exploring Ion Channel Magnetic Pharmacology: Are Magnetic Cues a Viable Alternative to Ion Channel Drugs?

We explore the potential of using magnetic cues as a novel approach to modulating ion channel expression, which could provide an alternative to traditional pharmacological interventions. Ion channels are crucial targets for pharmacological therapies, and ongoing research in this field continues to introduce new methods for treating various diseases. However, the efficacy of ion channel drugs is often compromised by issues such as target selectivity, leading to side effects, toxicity, and complex drug interactions.

Correction of Disorders in Psychoneurological Status and Functioning of Progenitor Cells of the Nervous Tissue with NF-κB Inhibitor under Conditions of Alzheimer's Disease Modeling.

We studied the effect of NF-κB blockade on the state of various pools of progenitor cells of the nervous tissue and the psychoneurological status of experimental animals with modeled Alzheimer's disease. Administration of scopolamine hydrobromide to C57BL/6 mice for 4 weeks was accompanied by the development of "persistent" disturbances in the orientation and exploratory behavior and mnestic function. An ameliorating effect of the NF-κB inhibitor on these cognitive disorders typical of senile dementia was revealed.

The Role of Smad3 in the Realization of the Growth Potential of Different Types of Neural Progenitor Cells and the Secretory Function of Neuroglia.

The features of the participation of Smad3 in the functioning of neural stem cells (NSC), neuronal committed precursors (NCP), and neuroglial elements were studied in vitro. It was found that this intracellular signaling molecule enhances the clonogenic and proliferative activities of NCP and inhibits specialization of neuronal precursors. At the same time, Smad3 does not participate in the realization of the growth potential of NSC.

Features of Intracellular Signal Transduction in Neural Stem Cells under the Influence of Alkaloid Songorine, an Agonist of Fibroblast Growth Factor Receptors.

We performed a comparative in vitro study of the involvement of NF-κB, PI3K, cAMP, ERK1/2, p38, JAKs, STAT3, JNK, and p53-dependent intracellular signaling in the functioning of neural stem cells (NSC) under the influence of basic fibroblast growth factor (FGF) and FGF receptor agonist, diterpene alkaloid songorine. The significant differences in FGFR-mediated intracellular signaling in NSC were revealed for these ligands. In both cases, stimulation of progenitor cell proliferation occurs with the participation of NF-κB, PI3K, ERK1/2, JAKs, and STAT3, while JNK and p53, on the contrary, inhibit cell cycle progression.
