Abstract Soft-tissue injuries affecting muscles, nerves, vasculature, tendons, and ligaments often diminish the quality of life due to pain, loss function, financial burdens. Both natural healing surgical interventions can result in scarring, which potentially may impede functional recovery lead persistent pain. Scar tissue, characterized by a highly disorganized fibrotic extracellular matrix, serve as physical barrier regeneration drug delivery. While approaches such drugs, biomaterials, cells, external stimulation, other forces show promise mitigating scarring promoting regenerative healing, their implementation remains limited challenging. Ultrasound, laser, electrical, magnetic forms stimulation have been utilized promote soft tissue well neural regeneration. After tissues experience increased proliferation Schwann secretion neurotropic factors, production myelin, growth all aimed at supporting axon innervation. Yet, outcomes vary depending on pathophysiology damaged nerve, timing following injury, specific parameters employed. Increased treatment intensity duration noted hinder process inducing damage. These modalities, either alone or combination with nerve guidance conduits scaffolds, demonstrated healing. However, literature currently lacks detailed understanding used for applications. In this article, we aim address gap summarizing existing reports providing an overview alongside associated outcomes.

Peripheral nerve injuries, especially those with complete transection of major nerves, create significant morbidity including debilitating pain, loss protective haptic feedback, and impaired volitional control musculature. The societal burden cost medical care for these injuries are enormous, estimates in the United States alone excess $670 million per year. In clinical scenarios a segmental gap where end-to-end coaptation without tension is not possible, "bridge" or scaffold must be interposed to facilitate communication between proximal distal stumps organized growth following Wallerian degeneration. A multitude constructs have been created studied this regeneration. Among three overall types bridge employed contemporary care-conduit/scaffold, allograft, autograft-each has downsides ranging from limited successful ingrowth donor site morbidity. Despite tremendous work over last 150 years biology technology treatment peripheral injury, biological processes governing regeneration remain incompletely understood. Especially cases long gaps, there remains room improvement. Ongoing studies identified several promising modalities scaffolds more efficient effective neuronal outgrowth but still require further investigation. Here, we review paradigms interposing reexamine physiology, regulatory programs regeneration, strategic targets neurogenic pathways that may novel modalities.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid-beta (Aβ) plaques and tau tangles, which contribute significantly to neuroinflammation, central driver pathogenesis. The activation microglia astrocytes, coupled with complex interactions between Aβ pathologies innate immune response, leads cascade inflammatory events. This process triggers release pro-inflammatory cytokines chemokines, exacerbating neuronal damage fostering cycle chronic inflammation that accelerates neurodegeneration. Key signaling pathways, such as nuclear factor-kappa B (NF-κB), Janus kinase/signal transducer activator transcription (JAK/STAT), mitogen-activated protein kinase (MAPK), phosphoinositide 3-kinase/protein (PI3K/Akt), are involved in regulating production these mediators, offering potential therapeutic targets for AD. Recently, extracellular vesicles (EVs) have emerged promising tool AD therapy, due their ability cross blood-brain barrier (BBB) deliver agents. Despite challenges standardizing EV-based therapies ensuring safety, EVs offer novel approach modulating neuroinflammation promoting neuroregeneration. review aims highlight intricate relationship emerging role therapeutics advancing treatment strategies.
