Mycoprotein Neuroplasticity: Leveraging Fungal Biosynthesis to Engineer Neuronal Damage Mitigation in Industrial Solvent-Exposed Populations

Digital painting showing molecular interplay between industrial solvents and neuronal damage in brain.
Figure 1: This detailed digital painting visualizes the complex molecular interactions between industrial solvents such as toluene, xylene, and trichloroethylene, and their effects on neuronal damage in the human brain. The image highlights key processes including the passage of these solvents through the blood-brain barrier, leading to oxidative stress, lipid peroxidation, neuroinflammation, and impaired synaptic transmission. Additionally, the painting incorporates the gut-brain axis, illustrating how gut microflora might interact with these pathways. Notably, it shows the potential intervention by fungal-derived antioxidants, depicted through bright, contrasting colors against a dark cosmic background, symbolizing the microscopic yet vast universe within the brain.

Industrial solvents, such as toluene, xylene, and trichloroethylene, are ubiquitous in manufacturing, painting, and chemical processing industries, exposing millions of workers worldwide to neurotoxic risks. Chronic exposure to these volatile organic compounds (VOCs) can lead to neuronal damage, manifesting as cognitive impairments, reduced neuroplasticity, and increased susceptibility to neurodegenerative disorders. Neuroplasticity, the brain's ability to reorganize synaptic connections in response to injury or environmental changes, is particularly vulnerable to solvent-induced oxidative stress and inflammation, which disrupt neuronal signaling and repair mechanisms (Klátyik et al., 2025). Emerging research highlights the potential of mycoproteins—proteins derived from fungal biomass—to mitigate such damage through bioactive compounds produced via fungal biosynthesis. Fungi, including species like Fusarium venenatum used in commercial mycoprotein production, biosynthesize a range of metabolites with neuroprotective properties, such as antioxidants and anti-inflammatory agents (Mapook et al., 2022).

This article synthesizes recent findings on solvent neurotoxicity and fungal biosynthesis, proposing novel hypotheses for engineering mycoproteins to enhance neuroplasticity in exposed populations. By bridging disparate fields—toxicology, mycology, and neuroscience—we speculate on underexplored intersections, such as fungal-derived peptides that could chelate neurotoxic solvents or modulate gut-brain axis pathways to promote neuronal repair. These integrative insights aim to generate new knowledge, highlighting gaps in current literature and posing provocative questions for future research, such as: Can genetically engineered fungi produce targeted mycoproteins that directly counteract solvent-induced hippocampal damage?

Solvent-Induced Neuronal Damage: Mechanisms and Vulnerabilities

Industrial solvents exert neurotoxic effects primarily through lipophilic penetration of the blood-brain barrier, leading to oxidative stress, lipid peroxidation, and disruption of neurotransmitter systems. For instance, toluene exposure has been linked to hippocampal atrophy and impaired synaptic plasticity, with conflicting studies showing both acute neuronal loss and compensatory neuroplastic responses (Klátyik et al., 2025; Kubat et al., 2025). Emerging subfields reveal that solvent neurotoxicity is exacerbated by gut microbiota dysbiosis, where VOCs alter microbial communities, indirectly amplifying brain inflammation via the gut-brain axis (Riva et al., 2025; Bhadoriya et al., 2025). This intersection is underexplored, with neglected directions including solvent-mediated changes in microbial-derived short-chain fatty acids that influence neuroplasticity.

Contradictions in the literature arise from dose-dependent effects: low-level chronic exposure may enhance neuroplasticity via hormesis, while high doses cause irreversible damage (Huang et al., 2025). Patterns across studies suggest that populations with genetic predispositions, such as polymorphisms in detoxifying enzymes, are more vulnerable, yet integrative frameworks unifying these findings are lacking. We propose a novel hypothesis: solvent exposure creates a "neurotoxic niche" where oxidative stress selectively impairs adult neurogenesis, but fungal interventions could restore balance by providing exogenous antioxidants that mimic microbial metabolites.

The image highlights essential compounds such as polysaccharides, triterpenoids, erinacines, phenolics, and antioxidant enzymes, each following distinct biochemical routes. The pathways converge to show neuroprotective actions against solvent-induced damage in neurons, underscoring the therapeutic potential of these fungi. The illustration serves as an educational tool, clearly delineating the synthesis and action of compounds with detailed annotations for each step involved.

Fungal Biosynthesis of Mycoproteins: Bioactive Potential for Neuroprotection

Fungal biosynthesis offers a versatile platform for producing mycoproteins rich in neuroprotective compounds, such as polysaccharides, phenolics, and peptides. Species like Ganoderma lucidum and Hericium erinaceus biosynthesize triterpenoids and erinacines that enhance neuroplasticity by promoting nerve growth factor (NGF) expression and reducing oxidative stress (Wang et al., 2025; Hashem et al., 2025). Recent advances in metabolomics reveal that fungal extracts from Aspergillus and Penicillium species contain hydroxyanthracene derivatives with anti-inflammatory properties, potentially mitigating solvent-induced neuroinflammation (Merino et al., 2025; Abdelhafez et al., 2025).

Underexplored intersections include engineering fungi to overproduce mycoproteins that target solvent-specific toxicities, such as chelating heavy metals in solvent mixtures or modulating microbial pathways in the gut (Ganguly et al., 2024; Shady et al., 2025). Conflicting results exist on fungal metabolite efficacy; for example, while some studies show strong antioxidant activity in vitro, in vivo translation is inconsistent due to bioavailability issues (Gulcin, 2025; Prajapati et al., 2025). We speculate that CRISPR-edited fungi could bridge this gap by incorporating solvent-detoxifying enzymes into mycoprotein structures, creating "designer" biosynthetics that enhance neuronal repair.

Figure 3: This conceptual illustration visualizes the complex interplay between engineered mycoproteins and neuroplasticity interventions. It showcases designer fungal strains geared towards producing targeted peptides such as BDNF mimics and solvent-chelating proteins. These elements are integrated into a schematic that also highlights gut microbiota modulation efforts. Pathways are clearly depicted to demonstrate how these interventions can enhance neuroplasticity and aid neuronal repair, particularly in individuals affected by solvent exposure. The flow and interconnectedness of biological and engineered systems underscore potential therapeutic approaches in neuroscience.

Engineering Mycoprotein Interventions: Speculative Frameworks and Hypotheses

Bridging solvent toxicology and fungal biotechnology, we propose integrative frameworks where mycoproteins are engineered to exploit neuroplasticity pathways. For instance, fungal biosynthesis could yield peptides that mimic BDNF (brain-derived neurotrophic factor), counteracting solvent-induced downregulation (Elsayyad et al., 2025; Boros et al., 2025). A unifying hypothesis posits that mycoprotein-enriched diets restore gut microbiota dysbiosis, enhancing neuroplasticity via the vagus nerve and immune modulation (Volpedo et al., 2025; Wadan et al., 2025).

Posing novel experiments, we suggest testing engineered Fusarium strains expressing solvent-chelating proteins in animal models of chronic exposure, measuring hippocampal neurogenesis as an endpoint. Gaps include the lack of longitudinal studies on mycoprotein bioavailability in solvent-exposed cohorts, and contradictions in fungal metabolite stability under industrial conditions. Speculatively, mycoprotein nanoparticles could deliver neuroprotective agents directly to the brain, bypassing bioavailability hurdles (Huo et al., 2025).

The image illustrates mycoprotein nanoparticles as they cross the blood-brain barrier, highlighting their targeted delivery to specific neuronal regions. The visualization captures the integration of this technology within the context of personalized medicine for industrial populations, emphasizing innovative pathways that navigate through blood vessels and interact with neuronal tissues. Futuristic tones and a gradient background enhance the depiction of these dynamic processes, showcasing the potential of advanced biotechnological applications in neuroprotection.

Conclusion

This synthesis underscores the transformative potential of leveraging fungal biosynthesis for mycoprotein-based mitigation of solvent-induced neuronal damage, with implications for occupational health in industrial populations. By integrating antioxidant, anti-inflammatory, and neuroplasticity-enhancing properties, engineered mycoproteins could offer a novel, low-cost intervention. Future directions include clinical trials in solvent-exposed workers and exploring fungal genetic engineering for targeted metabolite production. Open problems persist, such as optimizing mycoprotein delivery to the brain and addressing variability in human microbiomes. Ultimately, this speculative framework could pioneer "mycotherapy" as a preventive strategy, bridging environmental toxicology and biotechnology for enhanced neuroresilience.
