Discovery of Hybrid Brain Cells Redefines Neuroscience’s Landscape and Therapeutic Avenues

In the realm of neuroscience, an enormous shift is underway. For many years, it was widely believed that neurons and glial cells played a major role in organising the operations of the nervous system, especially the complex functions of the brain. This dogma seemed steadfast until recent groundbreaking discoveries shattered it. In a study published in the prestigious journal Nature, scientists have introduced us to a new player in this intricate orchestra of neural function – the “hybrid cell.”

Traditionally, neuroscientists have placed their primary focus on neurons, considering them the conductors of the neural symphony, responsible for processing and transmitting vital information within the intricate web of neural networks. It was once believed that glial cells, especially astrocytes, served as the immune system’s structural, energetic, and supporting components. Attention was drawn to these astrocytes in particular because of their proximity to synapses, which are crucial intersections where neurons communicate. Researchers speculated that astrocytes might be active participants in synaptic transmission and information processing, but conclusive evidence remained unclear, leading to conflicting results in prior studies.

Now follows the ground-breaking science that has changed the way we think about how the brain functions. A team of neuroscientists hailing from the Department of Basic Neurosciences at the Faculty of Biology and Medicine of the University of Lausanne (UNIL) and the Wyss Center for Bio and Neuroengineering in Geneva embarked on a mission to resolve the long-running debate. They were looking for a cell type with astrocytic features that also included the molecular machinery necessary for synaptic transmission, especially the release of glutamate, a crucial neurotransmitter used by neurons.

With the aid of cutting-edge single-cell transcriptomics, a thorough analysis of the molecular makeup of astrocytes served as the starting point for the process of revealing this hybrid cell. Researchers were able to find remnants of vesicular proteins, such as VGLUT, which fill neuronal vesicles used for glutamate release. Surprisingly, these transcripts proved to be retained in human cells as well, not just in mice. Additionally, the team discovered specialised proteins in these cells that are essential for glutamatergic vesicles’ efficient operation and quick communication with nearby cells.

The next step was to confirm the operation of these hybrid cells and their capacity to release glutamate at a pace comparable to synaptic transmission. The researchers harnessed advanced imaging techniques to visualize glutamate release from vesicles within brain tissues, even in live mice. The results were nothing short of extraordinary. A subgroup of astrocytes was identified that responded to selective stimulation with rapid glutamate release. This release occurred in spatially delimited areas of these cells, closely resembling the synaptic sites.

This finding has revealed a new class of cells that stand in between astrocytes and neurons. These hybrid cells release glutamate, which has a profound impact on synaptic transmission and controls neuronal excitation and communication. By reducing their VGLUT expression decreased long-term potentiation, which had an impact on mice’s memory and may provide treatments for neurodegenerative and memory-related diseases.

This breakthrough challenges the traditional understanding of brain function, opening new avenues for research and therapeutic targets in diseases like Parkinson’s and Alzheimer’s. Andrea Volterra, co-director of the study, envisions these cells as key players in neuroscience’s ongoing journey, holding immense research potential.

Sarah Burton has officially redefined Givenchy. In her Fall 2025 debut at Paris Fashion Week, the former Alexander McQueen creative director brought a feminine perspective to the legendary house, embracing strength, vulnerability, and emotional intelligence. This moment felt significant—not only because of Burton’s storied past but also because so few women currently helm major luxury brands.

A Tribute to Givenchy’s Heritage

Burton’s inspiration came from Hubert de Givenchy’s 1952 debut collection, known for its clean, graphic silhouettes. A recent discovery of the maison’s archival calico patterns further fueled her vision, leading to designs that balanced wearable ease with dramatic, couture-like elements.

The show opened with a black fishnet catsuit, a bold reset before transitioning into the essence of Burton’s Givenchy—a collection that honored the past while embracing modern femininity.

Key Looks & Defining Elements

Oversized Suits with Cinched Waists → A powerful balance of structure and fluidity.

Sleeveless Dresses with Ruffled Hemlines → Adding movement and drama to everyday elegance.

Cocoon-Like Coats & Jackets → Featuring rounded, puffed-up shoulders, nodding to Givenchy’s classic volume play.

Body-Diverse Runway Casting → One of the few Paris shows this season to feature a range of body types, reinforcing Burton’s commitment to dressing real women.

A New Vision for Modern Women

Burton’s Givenchy is about more than just clothes—it’s about how women want to feel: powerful, sexy, vulnerable, and strong, all at once. Her debut collection wasn’t just a runway success—it was a statement on the future of fashion, where femininity is both celebrated and redefined.

The soon-to-reopen L’Étoile du Nord train station near Gare du Nord in Paris, reinforcing the romanticism of travel through fashion.

A Vision of Travelers Through Time

The collection imagined travelers from different eras, dressed in Ghesquière’s futuristic Vuitton aesthetic. Some looked like commuters, others like luxury vacationers boarding the Orient Express, decked out in elegant outerwear and opulent layers. The result was a mix of wearable technical pieces and high-fashion statements, all rich in detail and storytelling.
