Enhancer-AAVs allow genetic access to oligodendrocytes and diverse populations of astrocytes across species

Enhancer-AAVs achieve over 95% cell type specificity in targeting oligodendrocytes and astrocytes across species, enabling detailed glial cell studies.

• Why it matters: Understanding glial cell diversity and function is limited by tools that lack specificity and cross-species applicability, hindering neurobiological research and disease insights.
• What they did: Researchers developed a new suite of enhancer-AAVs optimized for high expression and specificity, validated in rat and macaque, and capable of driving functional transgenes like Cre and iAChSnFR in astrocytes.
• The result: These tools enable detailed characterization of glial populations and their roles in various species, disease states, and behavioral contexts, exemplified by detecting reward-dependent acetylcholine responses in astrocytes.
