Early intervention to mitigate secondary brain injury is critical for neuronal protection. Sterile alpha and Toll/interleukin-1 receptor motif-containing 1 (SARM1), a member of the MyD88 family, is predominantly expressed in neurons, where it localizes to the outer membrane of mitochondria. Under physiological conditions, SARM1 is expressed at low levels; however, its expression increases following injury, resulting in excessive NAD⁺ hydrolysis. While NAD⁺ degradation products can influence calcium channels, their role in calcium regulation after ICH remains unclear. This study established an <em>in vivo</em> ICH model in adult SD rats via autologous blood injection into the basal ganglia and validated the findings using an <em>in vitro</em> model of primary neurons treated with oxyhemoglobin. SARM1 knockdown was achieved using a lentiviral vector. Following ICH, SARM1 expression significantly increased and colocalized with the neuronal marker NeuN. SARM1 knockdown reduced both SARM1 and mitochondrial calcium uniporter (MCU) expression, decreased NAD⁺ degradation, and attenuated neuronal death. Behavioral assessments demonstrated improved short- and long-term neurological outcomes in SARM1-knockdown rats compared with the lentiviral vector group. In <em>in vitro</em> experiments, Rhod-2 staining revealed reduced mitochondrial calcium levels, while TMRM staining indicated decreased mitochondrial membrane potential loss. Additionally, Hoechst staining showed reduced neuronal mitochondrial death following SARM1 downregulation. These findings suggest that targeting SARM1 may enhance neurological recovery and represents a potential therapeutic strategy for early intervention in secondary brain injury following ICH.</div></div>","PeriodicalId":19142,"journal":{"name":"Neuroscience","volume":"571 ","pages":"Pages 32-43"},"PeriodicalIF":2.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143528870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Self-adaptive serious games, which dynamically adjust task difficulty, may provide additional benefits by tailoring challenges to individual performance. However, the comparative effectiveness of self-adaptive versus progressive non-adaptive iVR interventions on motor learning in older adults remains underexplored. This randomized controlled trial primarily aimed to compare the effects of self-adaptive and progressive non-adaptive iVR interventions on motor learning in older adults. A total of 33 older adults were randomly assigned to either a self-adaptive (n = 17) or progressive non-adaptive (n = 16) iVR group. Both interventions involved an iVR serious game requiring unimanual reaching, target selection, and distractor inhibition under increasing difficulty over three days. Performance was evaluated pre- and post-intervention using a standardized iVR task, consisting of hitting a virtual target while ignoring distractors. This task features five levels of difficulty (level 0: no distractors; level 4: 17 low-saliency distractors). Primary outcomes, assessed during the standardized task, included changes in speed-accuracy trade-offs (SAT) and relative response time (RT, compared to level 0). Both participants and assessors were blinded to the intervention. After the intervention, both groups exhibited significant SAT improvements at level 1, 3 and 4 (P &lt; 0.05) and RT gains at level 3 and 4 (P &lt; 0.05). The self-adaptive group demonstrated significantly greater SAT (P = 0.049) and relative RT (P = 0.004) improvements at level 4.

Moreover, MR-PheWAS observed additional benefits associated with these two targets. Through analyses based on single-cell sequencing data, we identified critical cell types for KLC1, primarily megakaryocytes, and neurons, notably linked to the axon guidance pathway, while LANCL1 showed associations with B lymphocytes, neurons, and the electron transport pathway. In dorsal root ganglions, we identified enrichments of both LANCL1 and KLC1 in putative silent nociceptors.

The design involved sequences of four tones, where the last tone was either predictable (standard, S), completing the scale, or less predictable (deviant, D) when the first tone was occasionally repeated. In the passive condition, participants were instructed to ignore the sounds, whereas, in the active condition, they were asked to press the up or down arrow on a keyboard depending on whether the last tone of the sequence presented a higher or lower frequency than the previous one. This experimental design aimed to bias cognitive processing towards predictable (S) or unpredictable scenarios (D) in two different conditions: passive and attentional. EEG data from 13 channels were analyzed with Morlet wavelets, revealing event-related synchronization (ERS) and desynchronization (ERD) induced by the stimuli. Early theta activity was key in computing prediction errors and updating next-trial expectations. In the active condition, theta responses were higher in D than in S trials, indicating enhanced prediction error processing with attention. Early beta activity also increased during D, likely reflecting motor adjustments.

In this study, we examined the effects of EA at Baihui (GV20) and Yintang (GV29) on both behavioural deficits and glutamatergic synaptic transmission in Sprague-Dawley rats subjected to MS. First, we showed that EA effectively alleviated anhedonia and despair-like behaviours. Furthermore, our data indicated that EA restored the decrease in presynaptic glutamate release, as evidenced by changes in the frequency of miniature excitatory postsynaptic currents (mEPSCs) and paired-pulse ratios (PPR). Microdialysis results also suggested that EA elevated extracellular glutamate levels. To explore the underlying mechanisms, we performed Western blot analyses on several proteins involved in glutamatergic synaptic transmission. Notably, we found that EA treatment increased the expression of vesicular glutamate transporters (VGLUT1 and VGLUT2) and vesicle-associated release proteins (SNAP25, Syntaxin-1A, and VAMP2) in the medial prefrontal cortex (mPFC) of MS rats. In contrast, EA did not significantly affect most postsynaptic glutamatergic receptors.
