Several studies aimed to clarify the pathogenic mechanisms and involvement in various cell types. A crucial factor in ALS is autophagy, which plays a key role in degrading intracellular protein aggregates. The connection between ALS and autophagy is reinforced by the fact that several genes mutated in ALS are linked to fundamental aspects of autophagy. The blockage of the autophagic flux was observed in ALS motor neurons, where it occurs earlier than in glia. However, the inconsistent effects of autophagy modulators in preclinical and clinical studies indicate the need for a deeper understanding of the role of autophagy in other cell types, such as astrocytes, microglia, and oligodendrocytes. Astrocytes and microglia are significantly impacted by autophagy dysregulation, contributing to neurodegeneration in both mouse and human-derived models. Autophagy is overactivated early in the disease, even before symptoms appear. This overactivation is influenced by the timing and specific tissue involved. It can alter cells' immunophenotype, favouring proinflammatory responses and affecting the cellular environment and autophagy in the surrounding cells. In contrast, oligodendrocytes show mild autophagic alterations. Additionally, sex hormones may affect proper autophagy function and ALS progression. The lack of information on how sex influences autophagy in glia highlights the need for more nuanced investigation into this mechanism. Future research should focus on these aspects, paving the way for personalised pharmacological approaches that consider the roles of cell types, time of intervention, and sex.</div></div>","PeriodicalId":19097,"journal":{"name":"Neurobiology of Disease","volume":"218 ","pages":"Article 107203"},"PeriodicalIF":5.6,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145661496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While effective neuroprotective strategies in the preterm brain remain elusive, interventions such as skin-to-skin, developmental care, and music therapy have a positive impact on newborn brain development, potentially related to the oxytocinergic system. Endogenous oxytocin is recognized as a regulator of maternal-child social bonding, but its neuroprotective effect in the injured brain remains to be elucidated. Here, we investigated the effects of chemogenetic activation of oxytocinergic neurons on the neural correlates of EoP. Using a well-established mouse model of systemic interleukin-1β to induce EoP, we showed that neonatal chemogenetic activation of oxytocinergic neurons has anti-inflammatory effects in microglia, improving microstructural development of the corpus callosum and motor cortex, and rescuing typical social behavior. These neuroprotective effects were more pronounced in females, who showed a greater reduction in microgliosis and improved social behavior compared to males.

Early endosomal tubule fission (ETF) is essential for sorting cargoes for recycling and retrograde transport, yet the mechanisms coordinating this process are incompletely defined. Here, we identify the endoplasmic reticulum (ER)–resident protein protrudin—previously shown to promote axonal regeneration after injury—as a key regulator of ETF. Using CRISPR interference in human cells, we show that loss of protrudin causes marked accumulation of elongated endosomal tubules, caused by defective fission. Protrudin-mediated ETF required its ability to interact with ER-localised VAP proteins, endosomal phosphoinositides, and the kinesin motor KIF5, indicating a function at ER–endosome contact sites. The endosomal tubulation phenotype depended on dynamic microtubules and dynein and was phenocopied by KIF5 depletion, suggesting that protrudin coordinates opposing microtubule motor forces to drive fission. Beyond this direct role, protrudin connects multiple ETF machineries implicated in lipid transfer, actin regulation, and ER shaping, positioning it as a central scaffold for ETF. Importantly, depletion of protrudin or the HSP-associated kinesin KIF5A produced similar endosomal tubulation defects in human cortical neurons, underscoring the neurophysiological and disease relevance of this pathway.
