Control of goal-directed and inflexible actions by dorsal striatal melanocortin systems, in coordination with the central nucleus of the amygdala

This academic paper, authored by researchers Elizabeth C. Heaton, Esther H. Seo, Laura M. Butkovich, Sophie T. Yount, and Shannon L. Gourley, primarily explores the role of the melanocortin system in the dorsal striatum in controlling goal-directed behavior and inflexible behavior, particularly in inhibiting habitual behavior in the dorsolateral st...

Prefrontal-Subthalamic Theta Signaling Mediates Delayed Responses During Conflict Processing

Prefrontal-Subthalamic Theta Signaling Mediates Delayed Responses During Conflict Processing

The Role of Prefrontal-Subthalamic θ Signals in Regulating Delayed Responses in Conflict Processing Background and Research Objectives Conflict processing plays a crucial role in human behavioral regulation. When faced with conflicting information, making an accurate decision requires delaying the response to gain time to choose the appropriate beh...

Reactivating PTEN to Impair Glioma Stem Cells by Inhibiting Cytosolic Iron-Sulfur Assembly

Using the Suppression of Cytoplasmic Iron-Sulfur Cluster Assembly to Restore PTEN and Inhibit Glioma Stem Cells Background Glioblastoma (GBM) is one of the most lethal primary brain tumors. Glioma stem cells (GSCs) not only initiate and sustain the malignant phenotype but also enhance treatment resistance. Although PTEN frequently mutates in gliobl...

Hepatic Danger Signaling Triggers TREM2+ Macrophage Induction and Drives Steatohepatitis via MS4A7-Dependent Inflammasome Activation

Liver Danger Signal Triggers TREM2+ Macrophage-Mediated MS4A7-Dependent Inflammasome Activation Driving Steatohepatitis Background and Research Motivation In recent years, with the increasing incidence of metabolic dysfunction-associated steatohepatitis (MASH), its pathological mechanisms have garnered significant attention. MASH, formerly known as...

Identification of Hypoxic Macrophages in Glioblastoma with Therapeutic Potential for Vasculature Normalization

Identification of Hypoxic Macrophages in Glioblastoma with Therapeutic Potential for Vasculature Normalization

Identification of Therapeutic Potential of Hypoxic Macrophages in Glioblastoma Academic Background Glioblastoma (GBM) and isocitrate dehydrogenase (IDH) mutant gliomas are the most common malignant brain tumors in adults. Tumor-associated macrophages (TAMs) are the major immune cell infiltrates in these tumors. These cells interact directly with ma...
