Key Protein Essential for Smell and Survival Identified

The Orco protein is crucial for the survival of olfactory neurons in ants. Mutating the orco gene in Harpegnathos saltator ants drastically reduced their number of olfactory neurons, impairing their social interactions. This stud highlights the importance of Orco in neural development and social communication in ants. Understanding these mechanisms can provide insights into sensory-mediated social behavior in both animals and humans.

Aging Brain Cells Have Prolonged Death Process

Mature oligodendrocytes, crucial for brain function and myelin production, have an unusually prolonged death process after damage, surviving up to 45 days post-trauma, a stark contrast to the rapid demise of their younger counterparts within 24 hours. This study illuminates a previously unknown pathway of cell longevity, suggesting a potential shift in strategies for treating aging-related damage and neurodegenerative diseases like multiple sclerosis.

The Early Death of Nerve Cells Is Crucial to Form Healthy Brains

Apoptosis plays a critical role in brain development as it influences the thickness of layers in the cerebral cortex, variety, and layer cell density. Alterations in how cells perform division and apoptosis lead to the development of abnormal cortical structures as seen in a variety of neurodevelopmental disorders, including autism.
