A recent study published in Immunity demonstrated that intestinal epithelial DRD2 specifically promotes Experimental autoimmune encephalomyelitis (EAE) in female mice by altering the composition of the intestinal flora and its metabolites. This work was performed by researchers in Dr. Zhou Jiawei’s Lab, State Key Laboratory of Neuroscience, Dr. Xinyang Song’s Lab at the Center for Excellence in Molecular Cell Science, CAS; Dr. Zhu Zhengjiang’s Lab at the Interdisciplinary Research Center on Biology and Chemistry, Shanghai Institute of Organic Chemistry, CAS and Dr. Chen Sheng’s team at Ruijin Hospital, affiliated to the Shanghai Jiaotong University School of Medicine. This work has indicated that activation of the intestinal epithelial dopamine signaling pathway increases the susceptibility of females to central nervous system (CNS) autoimmune diseases, laying a foundation for sex-specific interventions for these diseases.
A recent study published in Cell has reported the generation of a live-birth chimeric monkey using a high contribution of embryonic stem cells (ESCs). This research was completed by Dr. LIU Zhen’s research team and Dr. SUN Qiang’s research team , and by Dr. Miguel A. Esteban’s research team.
Dr. LI Xue’s lab, developed a hyperflexible electrode array for long-term recording and decoding of intraspinal neural activities. This work was recently published on Advanced Science.
A recent study published in Neuroscience Bulletin demonstrated that theta oscillations support prefrontal-hippocampal interactions in sequential working memory. This work was performed by researchers in Dr. YE Zheng’s Lab and Prof. ZHAN Shikun.
A recent study published in Nature Communications revealed the topographic organization of high-level visual areas in human and monkey brains. This work was performed by researchers in Dr. CHANG Le’s Lab. This work systematically investigated how visual features are represented and organized in the primate temporal lobe by combining functional MRI, electrophysiology, and deep learning, paving the way for the development of artificial visual systems with brain-like topographic organization.
A recent study published in Nature Metabolism demonstrated that astrocyte-specific overexpression of TMEM164 alleviating symptoms of neurodegenerative diseases in mouse models. This work was performed by the researchers in Dr. ZHOU Haibo’s Lab. This work has successfully identified transmembrane protein TMEM164 as a key regulator of neurotoxic astrocyte reactivity, and found that TMEM164 overexpression inhibited the induction of neurotoxic reactive astrocytes and neuronal death in both mouse and human astrocytes, as well as in Alzheimer’s disease (AD) and Parkinson’s disease (PD) mouse models. This discovery provides a potential therapeutic target for neurodegenerative diseases associated with neurotoxic reactive astrocytes.
The laboratory of Dr. XU Chun revealed neural mechanisms underlying associative learning of discontinuous events and demonstrated the critical role of the hippocampal CA1-Subiculum circuit in trace fear conditioning by combining behavioral analysis, optogenetics, and Calcium imaging.
A research team led by Dr.WANG Zuoren discovered that the activity of dopamine type 2 receptor-expressing neurons (Drd2+ neurons) in the dorsal bed nucleus of stria terminalis (dBNST) increased after long-term social isolation following weaning, leading to sex-specific abnormal behavior in male and female rats, by using techniques such as patch-clamp electrophysiology, chemogenetics manipulation, in vivo pharmacology experiments, and behavioral analysis. This study elucidated the involvement of dopamine type 1 and type 2 receptor-positive neurons in the dBNST region in regulating anxiety-like behavior induced by long-term social isolation, providing potential therapeutic targets for emotional disorders caused by social isolation.
A recent study published in Cell successfully mapped the cell-type taxonomy in the macaque cortex and revealed the relationship between cell-type composition and various primate brain regions, by using the self-developed spatial transcriptome sequencing technology Stereo-seq and snRNA-seq technology. These findings provide a molecular and cellular basis for further investigation into neural circuits.
A recent study published in Cell Reports revealed the neural code for incomplete faces in the macaque face patches. This work was performed by researchers in Dr. CHANG Le’s Lab . This work systematically investigated how faces are represented in the primate brain when only a part of the face is shown, by conducting electrophysiological recordings in face-selective areas of the macaque inferotemporal cortex, paving the way for understanding the code of faces under natural conditions.
Chinese researchers led by Principal Investigator LIU Zhen, Principal Investigator SUN Qiang, and Dr. LU Zongyang, have develop an efficient gene integration method for rodent and primate embryos by MMEJ suppression. This gene knock-in method is referred to as CATI (CasRX-assisted Targeted Integration).
Recently, DU Jiulin’s research group, found the circadian regulation of synapse growth during neural development, taking the classic retinotectal synapse in zebrafish as an in vivo model implemented with the long-term time-lapse two-photon imaging. This study not only provides an important theoretical basis for the function of the circadian clock in regulating neural development, but also an important experimental basis for understanding the developmental rules of neuronal circuit formation.
