Although the effects of stress on the male mPFC have been extensively characterized, growing evidence demonstrates that females exhibit distinct behavioral, structural, and molecular responses to chronic stress. This review synthesizes current findings regarding sex differences in stress-induced plasticity within the adult mPFC, discussing the behavioral outcomes, activation, and neural plasticity of the region in response to stress exposure. Across stress paradigms, males generally exhibit earlier dendritic retraction, spine loss, and impairments in cognitive flexibility, whereas females often demonstrate delayed mPFC effects despite persistent affective behavioral deficits. Emerging evidence suggests that females may recruit compensatory inhibitory mechanisms, particularly through parvalbumin neuron activation, that transiently buffer pyramidal cells from stress-induced remodeling. In contrast, stress in males may influence mPFC structure and function via somatostatin interneuron signaling, glucocorticoid receptor-mediated pathways, and microglial-dependent synaptic remodeling. However, sex differences are strongly influenced by stress modality, duration, and intensity, which contributes to variability across studies. Despite this variability, patterns in the literature suggest that males and females recruit distinct mPFC mechanisms in response to stress. Improved understanding of sex-specific stress adaptations may inform the development of targeted interventions for stress-related psychiatric disorders.</p>","PeriodicalId":94058,"journal":{"name":"International review of neurobiology","volume":"190 ","pages":"31-54"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tissue morphology physiology and function are strongly dependent on the linked dynamic activities of the endomembrane of organelles of the endomembrane system (ES). This is especially true for nervous tissue and the brain where ES components must interact over long (neurite) distances for proper synapse functions. As the endoplasmic reticulum (ER) is the primary organelle responsible for generating plasma membrane and subcellular membrane components, dysregulation of the ER has a significant role in nervous tissue physiology and diseases in which membrane function is critical, such as in age associated Alzheimer's Disease (AD). Understanding why the ER fails to respond effectively to stress may provide a promising platform for developing antiaging treatments. In this review we characterizegene pathways induced by the transmembrane (TMEM) protein, TMEM230 in the ER in Alzheimer's disease (AD). TMEM230 upregulates oxidative phosphorylation and mitochondria pathways associated cell metabolism. High levels of expression of TMEM230 associated with AD, due chronic inflammation drives hyperoxidation leading to aberrant structural changes in the tethering of the mitochondria and ER membrane and consequently, intra-organelle calcium balance. Sustained elevated levels of expression of TMEM230 leads to catastrophic oxidative stress and irreversible mitochondria damage as seen in some AD patients.

Once thought to be inert, microplastics are now recognized as biologically active agents capable of accumulating in the body and causing toxic effects across organ systems. This review summarizes current evidence on their oxidative and inflammatory effects in the central nervous system (CNS) and the eye. Studies show that microplastics can cross biological barriers such as the blood-brain barrier (BBB) and blood-retinal barrier (BRB), where they are taken up by cells, impair mitochondria, and trigger inflammation. Microplastics have been found in cerebrospinal fluid, brain tissue, and ocular structures, raising concern about their link to neurodegenerative and retinal diseases, including Alzheimer's, Parkinson's, macular degeneration, and other disorders. Mechanistic data indicate activation of NF-κB and TGF-β1 pathways, promotion of protein aggregation, and disruption of neural signaling. In the eye, microplastics have been linked to oxidative stress, corneal thinning, and photoreceptor damage. However, human studies are limited due to challenges in detecting tiny particles and lack of microplastic-free controls. Research is further hindered by inconsistent definitions, particle diversity, and non-physiological exposure models. We highlight the need for standardized methods, multi-omics tools, and long-term studies to better understand exposure impacts.

While genetic and environmental factors have been associated with its onset, metabolic dysfunction has also been identified as one of the initial and most significant contributors its pathogenesis. The mitochondria are at the centre of this problem; their compromised function affects some crucial aspects of the neuronal health. Neurons have high energy demands so they are quite sensitive to the changes in the supply of the fuel. During AD pathogenesis, the loss of glucose transporters and the downregulation of key glycolytic enzymes deprives neurons of essential energy reserve. This metabolic dysregulation is further exacerbated by dysregulated lipid metabolism, pathological lipid droplet accumulation and ApoE4-driven failures in lipid trafficking which collectively leads to the oxidative stress, neuroinflammation, and Aβ aggregation. This situation is further aggravated by amino acid imbalances specifically within the glutamate-glutamine cycle. To counter this, ketone bodies have emerged as an alternative fuel source, capable of partially bypassing the impaired glucose oxidation while also demonstrating neuroprotective properties. Moreover, systemic metabolic disorders including type 2 diabetes mellitus, insulin resistance, obesity, and metabolic syndrome significantly amplify these deficits, functioning as major risk factors for AD onset and progression. Even the gut-brain axis plays a role in adding to the complexity.
