Astrocytes are star-shaped glial cells in the brain and spinal cord that play a crucial role in maintaining the blood-brain barrier, providing nutrients to neurons and regulating neurotransmitter ...

Astrocytes contribute to formation of the blood–brain barrier, participate in the maintenance of extracellular ionic and chemical homeostasis, are involved in the response to injury, and affect ...

More information: Astrocytic cannabinoid receptor 1 promotes resilience by dampening stress-induced blood–brain barrier alterations, Nature Neuroscience (2025). DOI: 10.1038/s41593-025-01891-9 ...

The blood-brain barrier (BBB) is a cellular fortress that regulates what ... it preferentially targeted neurons in neonatal mice and non-neuronal astrocytes in adult mice. 4 Given these changes, the ...

Astrocytes are star-shaped glial cells in the central nervous system that support neuronal function, maintain the blood-brain barrier, and contribute to brain repair and homeostasis.

Astrocytes are the most common cell in the central nervous system, and recently, they have emerged as key regulators of ...

The blood-brain barrier is a network of blood vessels and tissues that acts as a protective shield, preventing harmful substances in the blood from reaching the brain. In Alzheimer’s disease, this ...

The blood–brain barrier (BBB) is meant to protect the brain from noxious agents; however, it also significantly hinders the delivery of therapeutics to the brain. Several strategies have been ...

When faced with chronic stress, why do some people develop anxiety and depressive symptoms while others show resilience? The results of studies in mice, headed by researchers at Université Laval ...

CB1 receptors are abundant in neurons, but they’re also found in astrocytes, star-shaped cells allowing communication between the brain's blood vessels and neurons. “Astrocytes are an ...
