Glial futures and fermented traditions: A perspective on perinatal consumption of traditional African synbiotics, epigenetic glial programming, and offspring stress resilience

Microglia undergo critical developmental programming during the perinatal window, when environmental inputs can shape the neuroimmune function, synaptic development, and stress responsivity across lifespan. Stress resilience varies across individuals and populations, and the perinatal environment is crucial in calibrating the neural systems that govern adaptive responses. Preclinical mechanistic evidence reveals that glial cells play active role in the determination of the neurodevelopmental outcomes with interdependence on the gut microbiome operating through immune, endocrine, and metabolic signals. While the gut microbiome's role in brain development is now well documented, in this perspective, we examine whether traditional African fermented foods consumed during pregnancy and early postnatal life, particularly Ogi, may represent underexplored dietary exposures within this developmental framework. We therefore propose that fermented food with symbiotic-like properties could influence maternal and early life gut microbial ecology, microbial metabolite availability and downstream signalling relevant to glial maturation and hypothalamic-pituitary-adrenal axis calibration. This may potentially epigenetically program microglia and astrocytes during their critical developmental windows, as one of the mechanisms that may underpin lifelong stress resilience. we focus especially on short-chain fatty acids, tryptophan-derived metabolites, and one carbon nutrients as candidate mediators, and discuss how these may intersect with epigenetic regulation, neuroinflammatory tone, and stress-related circuitry during perinatal development. Functional enrichment analysis of literature curated gene panel identified neuroinflammation, HDAC regulation, and gut-brain axis signalling as the potential dominant biological signals, providing a probable computational support for the proposed mechanism. This hypothesis-generating framework grounded in microbiome, neurodevelopmental and nutritional literature insights therefore expose culturally embedded, community-specific model that take traditional dietary practices seriously as biological factor of neurodevelopmental significance.
