Cross-species single-cell transcriptomics reveals neuronal similarities and heterogeneity in amniote pallium

引用

Zoological Research 2025年第01期 193-208页

作者： Fu-Bao-Qian Huang Kuo Liao Yu-Nong Sun Zi-Hao Li Yan-Ru Zhang Ping-Fang Liao Si-Yuan Jiang Zhi-Yong Zhu Duo-Yuan Chen Ying Lei shi-Ping liu you-Ning Lin Zhen-Kun Zhuang School of Biology and Biological Engineering South China University of Technology BGI Research College of Life Sciences University of Chinese Academy of Sciences

The amniote pallium, a vital component of the forebrain,exhibits considerable evolutionary divergence across species and mediates diverse functions, including sensory processing, memory formation, and learning. However, the relationships among pallial subregions in different species remain poorly characterized, particularly regarding the identification of homologous neurons and their transcriptional signatures. In this study, we utilized singlenucleus RNA sequencing to examine over 130?000 nuclei from the macaque（Macaca fascicularis） neocortex,complemented by datasets from humans（Homo sapiens）,mice（Mus musculus）, zebra finches（Taeniopygia guttata）,turtles（Chrysemys picta bellii）, and lizards（Pogona vitticeps）,enablingcomprehensivecross-species comparison. Results revealed transcriptomic conservation and species-specific distinctions within the amniote pallium. Notable similarities were observed among cell subtypes, particularly within PVALB+inhibitory neurons,which exhibited species-preferred subtypes. Furthermore,correlations between pallial subregions and several transcription factor candidates were identified, including RARB, DLX2, STAT6, NR3C1, and THRB, with potential regulatory roles in gene expression in mammalian pallial neurons compared to their avian and reptilian counterparts. These results highlight the conserved nature of inhibitory neurons, remarkable regional divergence of excitatory neurons, and species-specific gene expression and regulation in amniote pallial neurons. Collectively,these findings provide valuable insights into the evolutionary dynamics of the amniote pallium.

D-DeepOCSORT: multi-object tracking algorithm based on LiDAR and monocular camera

引用

Optoelectronics Letters 2025年

作者： HE Xiao REN Shuai liu Chang shi Lei School of Information Engineering， Chang'an University School of Control of Robotic and Autonomous Systems， University of California Berkeley

Multi-object tracking is a fundamental problem in computer vision， and DeepOCSORT， due to its reliance on the 2D image position information of targets， tends to exhibit prediction drift. To enhance the tracking stability of DeepOCSORT， this paper proposes a novel multi-sensor data fusion-based multi-object tracking method. Specifically， we build upon the DeepOCSORT foundation and additionally integrate target velocity information directly measured by LiDAR. The introduction of this velocity information is conducted from three perspectives: firstly， during data association， a penalty term is constructed based on the differences in target velocities to constrain generating matches with consistent velocities; secondly， using LiDAR velocity for initialization and online updating of the velocity state within the tracker， making tracking predictions more stable; thirdly， controlling the degree of dependence on velocity information by adjusting the process noise covariance matrix. Evaluation results on the KITTI dataset demonstrate that compared to the original DeepOCSORT， the proposed improved multi-source heterogeneous information fusion method significantly enhances tracking performance， with maximum improvements of 3.35， 3.26， and 3.71 on the HOTA， MOTA， and IDF1 metrics， respectively. This study provides an effective approach to building a more stable and accurate multi-object tracking system.

TRIM66-HP1γ remodels the chromatin through phase separation

生物物理学报（英文） 2025年第1期11卷 18-33页

Chromatin contains not only heterochromatin (HC) and euchromatins (EC) but also facultative heterochromatin (fHC), which experience the dynamic remodeling between HCs and ECs by different regulators. The regulation of fHCs involves lots of different cell functions, like genomic stability and gene transcription. Heterochromatin protein 1 (HP1) recognizes methylated H3K9 and reshapes the chromatin into the fHCs through liquid–liquid phase separation (LLPS). Among the three members of the HP1 family, HP1α can condensate by itself and HP1β forms granules with the help of TRIM28, while the HP1γ cannot phase separation alone either and the coordinator is still unclear. So, in this study, we investigated the molecular mechanism of how HP1γ interacts with TRIM66 through PxVxL motif. Based on that, we examined the key regions that controlled the TRIM66-HP1γ co-phase separation behaviors both in vitro and in vivo. Furthermore, we proved that the liquid granules of TRIM66-HP1γ and chromatin highly correlated with H3K9me3 sites, which indicated the relationship with DNA damage response. Finally, combined with our previous study, we proposed the system for how TRIM66 remodeled the chromatin into compressed fHC through the TRIM66-HP1γ-H3K9me3 axis with liquid–liquid phase separation.
