Primary headache disorders, such as migraine and tension-type headache (TTH), represent a significant public health concern. Besides, cognitive/mental stress was suggested to contribute to TTH and ...

Despite the unique and complex nature of cancer pain, the activation of different ion channels can be related to the initiation and maintenance of pain. The transient receptor potential vanilloid 4 (TRPV4) is a cation channel broadly expressed in sensory afferent neurons. This channel is activated by multiple stimuli to mediate pain perception associated with inflammatory and neuropathic pain. Here, we focused on summarizing the role of TRPV4 in cancer etiology and cancer-induced pain mechanisms. Many studies revealed that the administration of a TRPV4 antagonist and TRPV4 knockdown diminishes nociception in chemotherapy-induced peripheral neuropathy (CIPN). Although the evidence on TRPV4 channels’ involvement in cancer pain is scarce, the expression of these receptors was reportedly enhanced in cancer-induced bone pain (CIBP), perineural, and orofacial cancer models following the inoculation of tumor cells to the bone marrow cavity, sciatic nerve, and tongue, respectively. Effective pain management is a continuous problem for patients diagnosed with cancer, and current guidelines fail to address a mechanism-based treatment. Therefore, examining new molecules with potential antinociceptive properties targeting TRPV4 modulation would be interesting. Identifying such agents could lead to the development of treatment strategies with improved pain-relieving effects and fewer adverse effects than the currently available analgesics.

Neurodegenerative diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and Amyotrophic Lateral Sclerosis, are characterized by multifactorial pathologies that extend beyond neuronal loss to include neuroinflammation, oxidative stress, mitochondrial dysfunction, and glial dysregulation. Despite extensive research, disease-modifying therapies remain elusive, hindered by late diagnosis, limited availability of specific biomarkers, and the persistent dominance of reductionist, single-target strategies. This comprehensive and informative review provides a critical synthesis of integrated neuroprotective strategies, with particular focus on glial mechanisms and biomarker-guided interventions. Therapeutic emphasis is placed on coordinated mechanisms targeting both neurons and non-neuronal cells, such as astrocytes, microglia, and oligodendrocytes. Emerging strategies are reported to include modulation of synaptic plasticity and neurotransmission, delivery of neurotrophic factors, activation of intrinsic cytoprotective pathways (e.g., Nrf2 signaling), restoration of proteostasis, and induction of regeneration via cellular reprogramming. Glial cells are discussed as therapeutic targets involved in inflammation, metabolism, myelination, and neuronal survival. Advances in predictive, preventive, personalized, and participatory (P4) medicine, supported by genomics, multi-omics, imaging, and real-world data, are presented as accelerating biomarker discovery and enabling earlier and more precise stage-specific interventions. Future success in combating neurodegeneration will depend on integrated approaches that combine protective, supportive, and regenerative strategies, appropriate for disease stage and patient profile. By reframing neuroprotection as a systemic, multicellular endeavor, this review highlights the potential to not only extend life expectancy, but also preserve meaningful quality of life in individuals affected by neurodegenerative diseases.

: Multiple sclerosis (MS) is a chronic neurodegenerative, inflammatory, and autoimmune disease characterised by the demyelination of the central nervous system. One of the main approaches for treating MS is the use of disease-modifying therapies (DMTs). Among the DMTs are interferons (IFNs), which are cytokines responsible for controlling the activity of the immune system while exerting immunomodulatory, antiviral, and antiproliferative activities. IFN-beta (IFN-β) is the first-choice drug used to treat relapsing-remitting MS. However, the administration of IFN-β causes numerous painful adverse effects, resulting in lower adherence to the treatment. Therefore, this study aimed to investigate the headache and flu-like pain symptoms observed after IFNβ injection in MS patients using a systematic review and meta-analysis of randomised controlled trials. A total of 2370 articles were identified through research databases. Nine articles were included (three involving IFNβ-1b and six involving IFNβ-1a). All studies included in the meta-analysis had a low risk of bias. The odds ratio of headache and flu-like pain symptoms increased in MS patients treated with IFN-β. Thus, the adverse effects of headache and flu-like pain symptoms appear to be linked to IFN-β treatment in MS. The protocol of the study was registered in the Prospective International Registry of Systematic Reviews (registration number CRD42021227593).
