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.

Zendaya’s Stylist Exposes Fashion Industry Rejection, Sparking Dialogue on Designer Choices
In a recent revelation that sent shockwaves through the fashion world, Zendaya’s longtime stylist, Law Roach, unveiled a surprising truth about the challenges the actress faced before her rise to stardom. During an episode of “The Cutting Room Floor” podcast, Roach candidly disclosed that several renowned luxury fashion houses had turned down opportunities to dress Zendaya early in her career. Despite the rejection, Zendaya has since become a fashion icon, prompting reflection on the dynamics of celebrity fashion and the power of designer choices.
Roach’s revelation shed light on the obstacles Zendaya encountered on her journey to success. He recounted reaching out to prestigious fashion houses such as Saint Laurent, Chanel, Gucci, Valentino, and Dior, only to receive rejections based on Zendaya’s perceived lack of prominence in the industry.
