Organ transplantation is an effective alternative treatment for patients with end-stage organ failure. However, the shortage of donor organs has limited the widespread application of clinical transplantation. In recent years, breakthroughs in CRISPR-Cas9 gene editing technology have overcome the barrier of hyperacute rejection in xenotransplantation, offering a potential solution to the organ shortage crisis. Rejection remains a critical factor affecting graft survival. Antigen-presenting cells play a vital role in the initiation and progression of rejection and immune regulation in xenotransplantation. Therefore, in-depth investigation into the role of antigen-presenting cells in xenotransplantation is of great significance. This article summarizes the roles and therapeutic strategies of professional antigen-presenting cells, including macrophages, dendritic cells and B cells in xenotransplantation, aiming to provide insights for future research on immune regulation mechanisms in this field.

ObjectiveTo investigate the characteristics of gray matter structure and clinical symptoms in patients with Alzheimer's disease (AD) comorbid with apathy (AD-A). MethodsThe study included 30 patients with AD-A, 30 AD disease patients without apathy (AD without apathy, AD-NA), and 30 healthy controls (HCs) matched in gender, age, and years of education. All participants underwent a comprehensive neuropsychological assessment and magnetic resonance imaging (MRI) scans. Voxel-based morphometry (VBM) was used to analyze changes in gray matter volume among the three groups. Additionally, the correlation between the identified abnormal brain regions and apathy scale scores was analyzed. ResultsThere were no statistically significant differences among the three groups in terms of age, gender, years of education, or total intracranial volume. Compared with the HCs group, both the AD-A and AD-NA groups showed significantly lower scores in cognitive function (P<0.001). The AD-A group exhibited significantly higher apathy scale scores compared with the AD-NA group (P<0.001). Compared with the AD-NA group, the AD-A group showed reduced gray matter volume in the bilateral caudate nucleus, left orbitofrontal cortex, lingual gyrus, inferior frontal gyrus, superior frontal gyrus, entorhinal cortex, right middle frontal gyrus and posterior cingulate cortex (FWE-corrected, P<0.05 for all). Compared with the HCs group, the AD-A group exhibited reduced gray matter volume in the bilateral middle temporal gyrus, left fusiform gyrus, calcarine sulcus, postcentral gyrus, right inferior frontal gyrus and supramarginal gyrus (FWE-corrected, P<0.05 for all). Compared with the HCs group, the AD-NA group showed reduced gray matter volume in the left precuneus, inferior temporal gyrus, and right inferior temporal gyrus (FWE-corrected, P<0.05 for all). In the AD-A group, changes in the gray matter volume of the left caudate nucleus (r= -0.557, P=0.002) and right middle frontal gyrus (r=-0.620, P=0.001) were negatively correlated with the apathy evaluation scale (AES) scores. ConclusionPatients in the AD-A group exhibited significant atrophy in the frontal-temporal-basal ganglia circuit, and the degree of gray matter atrophy was correlated with the severity of apathy.

ObjectiveTo conduct a comparative quality analysis of Inulae Flos, fuzz of Inulae Flos and calyx of Inulae Flos, elucidating the scientific connotation of the "removing calyx" process in the traditional processing of Inulae Flos. MethodsInulae Flos decoction pieces were collected, and the fuzz and calyx of Inulae Flos were prepared according to the experiences of old medicine workers. Subsequently, according to the methods under the "Inulae Flos" item in the 2025 edition of the Pharmacopoeia of the People's Republic of China, the appearance characteristics and thin-layer chromatography(TLC) identification of these samples were tested, and the moisture content, total ash content, extract content were also measured. The characteristic fingerprint patterns of Inulae Flos and fuzz of Inulae Flos were established by high-performance liquid chromatography(HPLC), followed by similarity evaluation, principal component analysis(PCA), and partial least squares-discriminant analysis(PLS-DA). The contents of cryptochlorogenic acid, caffeic acid, 1,3-O-dicaffeoylqunic acid, 1,5-O-dicaffeoylqunic acid, and 1-O-acetyl britannilactone were determined to compare the quality differences of Inulae Flos, fuzz of Inulae Flos, and calyx of Inulae Flos. ResultsThe moisture content of Inulae Flos, fuzz of Inulae Flos, and calyx of Inulae Flos was all<10%. The determination results of total ash content were as follows:Calyx of Inulae Flos>Inulae Flos>fuzz of Inulae Flos, and the determination results of alcohol-soluble extract content were as follows:Fuzz of Inulae Flos>Inulae Flos>calyx of Inulae Flos. HPLC fingerprint patterns of Inulae Flos and fuzz of Inulae Flos were established, and 22 common peaks were identified. The similarity analysis and PCA showed that the overall quality of Inulae Flos and fuzz of Inulae Flos was similar, while the overall quality of calyx of Inulae Flos differed significantly from that of Inulae Flos and fuzz of Inulae Flos. PLS-DA results showed that Inulae Flos, fuzz of Inulae Flos, and calyx of Inulae Flos clustered into distinct groups, indicating significant differences among them. Cryptochlorogenic acid and caffeic acid had relatively high contents in calyx of Inulae Flos, the contents of 1,3-O-dicaffeoylqunic acid and 1,5-O-dicaffeoylqunic acid in Inulae Flos and fuzz of Inulae Flos were higher than those in calyx of Inulae Flos. The order of 1-O-acetyl britannilactone content was determined as follows:fuzz of Inulae Flos>Inulae Flos>calyx of Inulae Flos. ConclusionThe scientific nature of "Removing Calyx" process in the cleansing of Inulae Flos by old medicine workers is demonstrated by the resulting fuzz of Inulae Flos decoction pieces exhibiting enhanced cleanliness and higher content of the index component 1-O-acetyl britannilactone. This study provides a reference basis for further improving and enhancing the processing method and quality control standards of Inulae Flos.

Objective To construct glucose oxidase(GOx)–loaded nanogels (GONGs), optimize their formulation, and evaluate their capacity to inhibit the Warburg effect in glioma cells. Methods A responsive polymer (HAM) was synthesized and used to self-assemble GONGs, which were then characterized. Encapsulation efficiency and drug loading were determined using fluorescence spectrophotometry. Biocompatibility was tested by measuring cytotoxicity and hemolytic activity. Western blotting was used to evaluate the effects of GONGs on the expression of proteins associated with the Warburg phenotype and oxidative damage in glioma cells. Results GONGs prepared at a drug–to–polymer ratio of 1∶10 exhibited a particle size of 140.3 nm and a zeta potential of −27.2 mV. Compared with free GOx, GONGs markedly reduced cytotoxicity, increased the IC50 in hUVEC cells from 2.150 nmol/L to 74.86 nmol/L, and significantly decreased hemolysis. At a GOx concentration of 2 nmol/L, GONGs effectively downregulated glycolysis-related proteins, such as HK2 and LDHA, and inhibited glutamine metabolism in glioma cells. Conclusion GONGs exhibited high GOx loading capacity, significantly reduced GOx-induced cytotoxicity, inhibited the Warburg effect in glioma cells and induced oxidative damage.

Traditional Chinese medicine(TCM) is the pillar for the development of motherland medicine, and animal medicine has a long history of application in China, characterized by wide resources, strong activity, definite efficacy, and great benefits. It has significant potential and important status in the consumption market of raw materials of TCM. In the context of global climate change, farming system alterations, and low renewability, the depletion of wild medicinal animal resources has accelerated. Accordingly, the conservation and sustainable utilization of wild resources of animal medicinal materials has become a problem that garners increasing attention and urgently needs to be solved. This paper summarizes the current situation of domestic and foreign medicinal animal breeding and research progress in industrial application in recent years and points out the issues related to standardized breeding, germplasm selection and breeding, and quality evaluation standards for medicinal animals. Furthermore, this paper discusses standardized breeding, quality standards, resource protection and utilization, and the search for alternative resources for rare and endangered medicinal animals. It proposes that researchers should systematically carry out in-depth basic research on animal medicine, improve the breeding scale and level of medicinal animals, employ modern technology to enhance the quality standards of medicinal materials, and strengthen the research and development of alternative resources. This approach aims to effectively address the relationship between protection and utilization and make a significant contribution to the sustainable development of medicinal animal resources and the animal-based Chinese medicinal material industry.

To improve the quality evaluation system of Hibisci Mutabilis Folium, this study established high performance liquid chromatography(HPLC) fingerprints of Hibisci Mutabilis Folium and evaluated the quality differences of medicinal materials from different places of production by chemometrics. Furthermore, a content measurement method of differential components was established based on quantitative analysis of multi-components by single-marker(QAMS). The fingerprints of 17 batches of Hibisci Mutabilis Folium from different places of production were constructed, with a total of 19 common peaks marked and seven components confirmed. The similarity between the sample fingerprints and the reference fingerprints ranged from 0.890 to 0.974. By utilizing principal component analysis(PCA), hierarchical cluster analysis(HCA), and orthogonal partial least squares-discriminant analysis(OPLS-DA), the chemical patterns of fingerprints were identified. Five components that could be used to evaluate the quality differences of Hibisci Mutabilis Folium were screened, namely peak 6(quercetin 3-O-β-robinobioside), peak 7(rutin), peak 9(kaempferol-3-O-β-robinobioside), peak 10(kaempferol-3-O-rutinoside), and peak 14(tiliroside). The relative correction factors of isoquercitrin, kaempferol-3-O-β-robinobioside, kaempferol-3-O-rutinoside, kaempferol-3-O-β-D-glucoside, and tiliroside were measured with rutin as the internal reference. The QAMS method was established for the content measurement of six flavonoids, and the results showed there was no significant difference compared to the results obtained by an external standard method. In summary, the HPLC fingerprints and QAMS method established in the study, demonstrating stability and accuracy, can provide a reference for the overall quality evaluation of Hibisci Mutabilis Folium.

Dysregulation of p53 and phosphoinositide (PIPn) signaling are both key drivers of oncogenesis and metastasis. Our recent findings reveal a previously unrecognized interaction between these pathways, converging in the nucleus to form a PIPn-p53 signalosome that modulates nuclear AKT activation and downstream signaling, thereby influencing cancer cell survival and motility. This review examines recent insights into nuclear PIPn signaling in the context of established roles for p53 in cell dynamics and migration while also deliberating current research on how nuclear PIPns interact with p53 to form signalosomes that affect cell motility. We emphasize the critical role of PIPns in stabilizing p53 and activating de novo nuclear AKT signaling, which subsequently modulates key motility-related pathways. Understanding the unique operation and function of the PIPn-p53 signalosome in nuclear phosphatidylinositol 3-kinase (PI3K)-AKT activation offers novel therapeutic strategies for controlling cancer metastasis by targeting pertinent interactions and events.

Advancements in artificial intelligence (AI) and emerging technologies are rapidly expanding the exploration of chemical space, facilitating innovative drug discovery. However, the transformation of novel compounds into safe and effective drugs remains a lengthy, high-risk, and costly process. Comprehensive early-stage evaluation is essential for reducing costs and improving the success rate of drug development. Despite this need, no comprehensive tool currently supports systematic evaluation and efficient screening. Here, we present druglikeFilter, a deep learning-based framework designed to assess drug-likeness across four critical dimensions: 1) physicochemical rule evaluated by systematic determination, 2) toxicity alert investigated from multiple perspectives, 3) binding affinity measured by dual-path analysis, and 4) compound synthesizability assessed by retro-route prediction. By enabling automated, multidimensional filtering of compound libraries, druglikeFilter not only streamlines the drug development process but also plays a crucial role in advancing research efforts towards viable drug candidates, which can be freely accessed at https://idrblab.org/drugfilter/.

Drug development encompasses multiple processes, wherein protein subcellular localization is essential. It promotes target identification, treatment development, and the design of drug delivery systems. In this research, a deep learning framework called LocPro is presented for predicting protein subcellular localization. Specifically, LocPro is unique in (a) combining protein representations from the pre-trained large language model (LLM) ESM2 and the expert-driven tool PROFEAT, (b) implementing a hybrid deep neural network architecture that integrates convolutional neural network (CNN), fully connected (FC) layer, and bidirectional long short-term memory (BiLSTM) blocks, and (c) developing a multi-label framework for predicting protein subcellular localization at multiple granularity levels. Additionally, a dataset was curated and divided using a homology-based strategy for training and validation. Comparative analyses show that LocPro outperforms existing methods in sequence-based multi-label protein subcellular localization prediction. The practical utility of this framework is further demonstrated through case studies on drug target subcellular localization. All in all, LocPro serves as a valuable complement to existing protein localization prediction tools. The web server is freely accessible at https://idrblab.org/LocPro/.
