Schizophrenia is a chronic, severe, and highly heterogeneous psychiatric disorder. Current antipsychotic medications show limited effectiveness in treating negative symptoms and cognitive deficits. Accumulating evidence suggests that dysfunction of inhibitory γ-aminobutyric acid (GABA) neurons, leading to inhibitory circuit dysregulation, plays a pivotal role in the pathophysiology of the disorder. Recent advances in induced pluripotent stem cells (iPSCs) and brain organoid technologies have provided more accurate human-based models of schizophrenia, offering new avenues to investigate the complex neurodevelopmental mechanism of schizophrenia and to explore cell replacement therapies. Preclinical studies have demonstrated that transplantation of specific types of GABAergic interneuron precursors into the brain can selectively improve negative symptoms and cognitive deficits in animal models, highlighting considerable translational potential. However, the transition from bench to bedside still faces multiple technical and ethical challenges, enhancing cell differentiation efficiency, ensuring long-term safety of transplanted cells, achieving precise control and functional integration of neuronal subtypes, understanding circuit-specific contributions to different symptom domains, and establishing rigorous ethical and regulatory frameworks. In summary, inhibitory GABAergic interneuron-based cell therapy provides a novel theoretical and perspective foundation for improving negative and cognitive symptoms of schizophrenia. Despite significant challenges ahead, its prospects remain highly promising.

Lung cancer is one of the most common cancers worldwide, and its mortality rate remains high. In addition to conventional surgery, radiotherapy, and chemotherapy, immunotherapy methods have been developed and used in recent years for the treatment of non-small cell lung cancer (NSCLC). However, only a small number of patients with NSCLC can benefit from immunotherapy strategies, and some patients even have hyperprogression after receiving immunotherapy. Therefore, precision immunotherapy requires effective biomarkers to guide it. In this paper, tissue samples, blood samples, intestinal microbiota, and other biomarkers are reviewed according to different sample sources. Blood samples, including TCR immune repertoire, Tregs cells, cytokines, lactate dehydrogenase, and other markers, are summarized and analyzed to provide reference for clinicians' diagnosis and treatment decisions.

Objective:To investigate the effects of subcutaneous immunotherapy (SCIT) on patients′ immune markers and metabolic levels in the early stage of allergen treatment, and to gain insight into the role of SCIT in regulating immune responses and metabolic levels, so as to provide reference data for the further discovery of potential biomarkers.Methods:A longitudinal study was used to include 40 subjects who underwent SCIT with dust mite allergens in the Department of Pediatrics of the First Affiliated Hospital of Guangzhou Medical University between November 2017 and February 2022, including 20 subjects each of single mite subcutaneous immunotherapy (SM-SCIT) and double mite subcutaneous immunotherapy (DM-SCIT). In this study, levels of dust mite allergen-specific antibodies and polyunsaturated fatty acid metabolism were measured before and 12 months after treatment, while pulmonary function tests were performed. The therapeutic effects of the patients were followed up by visual analogue scale (VAS), asthma control test (ACT) and total medication scores (TMS). The results were statistically analyzed using t-test and Mann-Whitney U-test. Results:After 12 months of treatment with SCIT, both groups showed a significant decrease in total VAS score (SM-SCIT: Z=-2.298, P<0.05; DM-SCIT: Z=-3.411, P<0.001); total ACT score (SM-SCIT: Z=-2.054, P<0.05; DM-SCIT: Z=-2.014, P<0.05) and total medication scores (SM-SCIT: Z=-3.799, P<0.000 1; DM-SCIT: Z=-3.474, P<0.001) were significantly higher, in addition to significantly higher MMEF75/25 values in the DM-SCIT group ( t=-2.253, P<0.05). There was no significant change in sIgE in the SM-SCIT group ( P>0.05), and the sIgG4 levels of the Der p, Der f, p 1, p 2, f 2, and p 21 fractions were significantly elevated ( Z=-2.651, -3.771, -2.949, -2.912, -2.725, -2.128, and -3.285, respectively, all P<0.05); The sIgE of Der p 2, f 2, p 7 and p 23 fractions( Z=-2.651, -3.771, -2.949, -2.912, -2.725, -2.128, -3.285, all P<0.05) and the sIgG4 levels of the Der p, Der f, p 1, p 2, f 1, f 2, p 10, p 21 and p 23 fractions ( Z=-3.808, -3.845, -3.061, -2.688, -2.464, -3.211, -2.371, -2.091, -2.427, all P<0.05) of the DM-SCIT group were significantly elevated. Metabolomics analysis showed that arachidonic acid, docosahexaenoic acid, docosapentaenoic acid, eicosapentaenoic acid, 5, 9, 12-octadecatrienoic acid, 5(S)-hydroxylated eicosatetraenoic acid, and dihomo-gamma-linolenic acid were significantly elevated at the beginning of the treatment period after SM-SCIT treatment ( Z of -2.191, -2.497, -1.988, -2.090, -2.19, -2.803, -2.073, all P<0.05); 5(S)-hydroxylated eicosatetraenoic acid showed elevated and alpha-linolenic acid, eicosadienoic acid, and eicosapentaenoic acid were significantly decreased in the DM-SCIT group after treatment ( Z=-1.988, -2.090, -2.497, -1.988, respectively, all P<0.05). Correlation analysis showed that arachidonic acid was significantly negatively correlated with changes in dust mite-specific IgG4 ( r=-0.499, P<0.05), and that alpha-linolenic acid, 5, 9, 12-octadecatrienoic acid, and eicosapentaenoic acid were positively correlated with the ΔsIgG4 of the dust mite der p 2 ( r=0.451, 0.420, 0.474, respectively; all P<0.05). Conclusion:Significant changes in allergen-specific antibody levels and polyunsaturated fatty acid metabolism levels occur during SCIT, and the two may interact and influence each other.
