Astrocyte necklace | 18K gold vermeil
In 2002 you published your first paper on glial cells and the astrocyte felt invisible. Decades later the field caught up. The astrocyte is not just scaffolding. It is the most abundant cell type in the central nervous system and an active player. The 29 mm gold necklace marks that shift in understanding.
The Science Behind the Astrocyte
Astrocytes are star-shaped glial cells and the most abundant cell type in the central nervous system by some counts. Historically positioned as passive support, recent research has revealed active roles in brain function. Astrocytes form the blood-brain barrier, buffer extracellular potassium, take up and recycle glutamate from synapses, provide metabolic support to neurons, and modulate the tripartite synapse. They are marked by glial fibrillary acidic protein (GFAP). Activated astrocytes in response to stroke, neurodegeneration, and neuroinflammation may both help and harm neural tissue depending on context. Contemporary neuroscience increasingly recognizes astrocyte heterogeneity and the cell's role as a non-linear signaling partner in neural circuits, not merely a background support structure.
Who Tends to Wear This
- neuroscientists and glia researchers who study astrocyte biology, signaling, or metabolism
- clinical neurologists treating stroke, neurodegeneration, or neuroinflammation
- researchers who work on blood-brain barrier function or glial-neural interactions
- people whose understanding of the astrocyte shifted over time and want to mark that evolution
Most often given at the moment someone's research recognizes what the astrocyte does.

FAQ
Who wears the astrocyte necklace?
Glia researchers, neurobiologists, clinical neurologists, and anyone whose career touches the blood-brain barrier or glial-neural signaling. Also people who remember when astrocytes were treated as invisible background and recognize how much the field has changed. The astrocyte necklace is often a personal piece, not just a professional one.
Why did the astrocyte stay invisible for so long?
Astrocytes don't fire action potentials the way neurons do, so early electrophysiology missed them. They don't have a single clearly mapped function the way neurons have synaptic transmission. For decades they were thought of as glue, not signal-carrying cells. Modern two-photon imaging, calcium imaging, and patch-clamp recording of astrocytes revealed that they were active all along. We were just using the wrong tools to see them. The shift from "scaffolding" to "active signaling partner" is one of the major recalibrations in neuroscience of the past 20 years.
What size and material?

Is there a silver version of the astrocyte?
Not currently. The astrocyte is positioned as a gold milestone piece, typically worn by researchers whose careers have shifted in tandem with the field's understanding of glial cells. If silver is your material preference, let us know and we can explore that for you.
