Mitochondria Express Functional Signaling Ligand-Binding Receptors that Regulate their Biological Responses - the Novel Role of Mitochondria as Stress-Response Sentinels.
Stem Cell Rev Rep

Evidence accumulated mitochondria, as the "powerplants of the cell," express several functional receptors for external ligands that modify their function and regulate cell biology. This review sheds new light on the role of these organelles in sensing external stimuli to facilitate energy production for cellular needs. This is possible because mitochondria express some receptors on their membranes that are responsible for their autonomous responses.

Humans possess a remarkable ability to discriminate a wide range of odors with high precision. This process begins with olfactory receptors (ORs) detecting and responding to the molecular structures of odorants. Recent studies have aimed to associate the activity of a single OR to an odor descriptor or predict odor descriptors using 2D molecular representation.

Understanding the detailed mechanism of action of glucagon-like peptide 1 receptor (GLP-1R) agonists on distinct topographic and genetically-defined brain circuits is critical for improving the efficacy and mitigating adverse side effects of these compounds. In this mini-review, we propose that the central nucleus of the amygdala (CeA) is a critical mediator of GLP-1R agonist-driven hypophagia. Here, we review the extant literature demonstrating CeA activation via GLP-1R agonists across multiple species and through multiple routes of administration.

Introduction: Non-segmental vitiligo (NSV) is an autoimmune condition characterized by melanocyte loss. While skin-specific mechanisms are well-studied, systemic immune dysregulation contributing to NSV pathogenesis remains unclear.
Objective: This study employs a multi-omic single-cell approach to investigate circulating immune cells in NSV, integrating transcriptional and chromatin accessibility data.

Non-small cell lung cancer (NSCLC) is a widespread highly malignant type of lung cancer. Conventional chemotherapeutic drugs may be accompanied by both drug resistance and serious side effects in patients. Therefore, safer and more effective medications are urgently needed for the treatment of NSCLC.
