- This narrative review synthesizes current evidence on incidence, the immunologic basis of hypersensitivity-including the recently clarified role of anti-PEG (rather than anti-protein) antibodies-genetic predisposition, differential diagnosis from asparaginase-associated hyperammonemia, therapeutic drug monitoring (TDM), and desensitization. Hypersensitivity to PEG-asparaginase is a frequent, clinically consequential complication of pediatric acute lymphoblastic leukemia therapy that can compromise treatment exposure and survival. Recombinant Erwinia asparaginase (crisantaspase) is now licensed in the United States (2021) and the European Union (2023) for hypersensitive patients; however, cost, reimbursement, and local availability continue to limit access in many settings. Therefore, strategies for the safe continuation of PEG-asparaginase remain clinically relevant for reasons other than supply shortages alone. Using Ponte di Legno Toxicity Working Group definitions, reactions are classified as clinical allergy, allergic-like reaction, or silent inactivation, each requiring a different response; TDM is central to making this distinction. Genetic susceptibility loci (HLA class II haplotypes, CNOT3, GRIA1) remain investigational, with moderate effect sizes and inconsistent replication, and are not yet suitable for clinical decision-making. An adapted multi-step desensitization protocol can preserve therapeutic enzyme activity in appropriately selected patients; however, tolerance is temporary and dose-specific and requires repeat TDM after every dose. Conclusion. A personalized, multidisciplinary approach-integrating TDM, realistic assessment of access to alternative formulations, and (where available) genetic data-is recommended to optimize treatment safety and antileukemic efficacy. - Source: PubMed

Prelog TomažKavčič MarkoIvancan SimonaSalobir NežaJazbec Janez - Our previous study demonstrated that HDAC1 knockdown alleviates traumatic brain injury (TBI), although underlying mechanisms remain unclear. Given the importance of microglial polarization in brain repair and its association with protein lactylation, this study investigated whether neuroprotective effects of HDAC1 inhibition in TBI are mediated through regulation of microglial polarization. In vivo TBI models, in vitro microglial cultures, immunofluorescence, CUT&Tag-seq and RNA-seq were employed to investigate the role of HDAC1 in TBI and its effects on microglial polarization and histone lactylation. Following TBI, microglia exhibited a predominant M1 phenotype with elevated HDAC1 expression, reduced histone lactylation, and altered expression of CD86 and CD206. Pharmacological inhibition of HDAC1, particularly with suberoylanilide hydroxamic acid (SAHA), or lactate supplementation restored histone lactylation and promoted M2 polarization. CUT&Tag-seq and qRT-PCR revealed that HDAC1 inhibition increased histone lactylation at the Gria1 promoter, leading to Gria1 upregulation in microglia. Hyperlactylated genes were enriched in neuroactive ligand-receptor interaction pathway. Overexpression of Gria1 in BV2 cells promoted M2 polarization, characterized by increased CD206 and decreased CD86 expression, which was further enhanced by HDAC1 inhibition or lactate treatment. RNA-seq identified SPP1 as a key downstream effector of Gria1 involved in immune and inflammatory responses. Knockdown of SPP1 suppressed CD206 and abolished the M2 polarization induced by Gria1 overexpression and HDAC1 inhibition. In a mouse TBI model, SAHA improved neurological recovery, reduced cortical lesions, upregulated Gria1 and SPP1, increased CD206, decreased CD86, and attenuated microglial activation. Collectively, pharmacological inhibition of HDAC1-mediated histone delactylation at the Gria1 promoter enhances Gria1-dependent SPP1 expression, thereby promoting microglial M2 polarization and attenuating neuroinflammation after TBI. - Source: PubMed

Chen YimingWei LiangJi TongjieZhao KaijunZhong Chunlong - Working memory refers to the multifaceted cognitive systems that are considered necessary for retaining information while performing complex tasks, such as reasoning and learning in humans. In vertebrates, working memory is evident as a conserved alternating searching strategy. We can use automated tracking tools to measure this search strategy in Xenopus tadpoles. The free-movement pattern Y-maze assay is validated for assessing spatial working memory and cognitive flexibility in Xenopus. Deviations from randomness in search strategies are quantified by comparing relative alternating and repeating Y-maze arm entry choices within a 60-min time period in the maze. Pharmacologically or genetically abolishing working memory in these tadpoles disrupts their search strategy and adaptive behavior in a Y-maze arena, providing a valuable model to investigate intellectual disabilities and the architecture of cognition. In this chapter, we present our protocol for measuring working memory and locomotive ability in Xenopus using automated behavioral tracking equipment along with our recommended sample collection procedure for genotyping. We routinely use this protocol to investigate neurodevelopmental phenotypes, providing in vivo functional evidence to support patient diagnoses for novel disorders such as those affecting GRIA1 and DDX17. - Source: PubMed

Huang ZhenyuXu JingyiGao JiahuaLin HangjuanWu QuanChen JiangGao LinchaoPeng XinLou HongkanHu Hongwei - Glutamatergic neuron-to-glioma signaling mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) has emerged as an important mechanism in glioma progression. We analyzed the expression of the AMPAR subunit genes , , , and in lower-grade glioma (LGG). Expression of - was highest in IDH-mutant/1p19q-codeleted tumors and lowest in IDH-wildtype tumors across both The Cancer Genome Atlas (TCGA) and the Chinese Glioma Genome Atlas (CGGA) cohorts. High expression of each gene was associated with longer overall survival (OS). Transcriptome-wide analyses identified positive correlations between an AMPAR score and genes involved in synaptic organization, neuronal connectivity, and neurotransmission. Co-expression analyses demonstrated coordinated expression between - and genes encoding AMPAR auxiliary proteins. Gene Ontology (GO) enrichment revealed overrepresentation of synaptic signaling, trans-synaptic communication, and synapse organization. Although the AMPAR score was associated with favorable survival in univariate analyses, it did not retain independent prognostic significance after adjustment for key clinicomolecular variables. Elevated expression of AMPAR subunit genes in LGG was associated with favorable molecular subtypes and a synaptic transcriptional program. These findings suggest that - expression is associated with a synaptically enriched transcriptional program in LGG, although its cellular origin remains uncertain. - Source: PubMed
