Three Key Considerations For Precise Neuronal Targeting Using AAV Technologies

Posted by Susanna Bachle on Nov 27, 2019 9:03:45 AM

Understanding the biology behind brain development, learning, and behavior poses many challenges in neuroscience with many brain regions, neuronal networks, and specific neuronal populations to consider. To tease apart how different neurons impact a certain output, neuroscientists have begun to use more precise genetic tools: activators, inhibitors, sensors, recombinases, and more. With the help of adeno-associated viral vectors (AAV), neuroscientists can combine classical genetic tools with the manipulation of specific neuronal subtypes and determine how these changes affect the phenotype. Viral vectors and genetic approaches are continuously refined and developed so there are many combinations to choose from for your experiments!

Find and Share AAV Data with Addgene's New AAV Data Hub

Posted by Melina Fan on Oct 8, 2019 8:33:52 AM

Dear scientists using AAV,

We hear your questions! How much virus should I inject? How long do I need to wait? What serotype and promoter should I use to target my favorite neurons?

We don’t know all of the answers, but we’re betting that your colleagues do. That’s why we’re launching the AAV Data Hub. The Data Hub is an open platform for scientists using AAV to share practical information about their experiences. It will contain all of the juicy and important details that you won’t find in the final publication and we have already collected over 100 entries spanning six different species and dozens of different expression sites.

Deciphering the Mysteries of Behavior with Viral Vectors

Posted by Klaus Wanisch on Sep 17, 2019 8:40:54 AM

Over the past decades, neuroscientists have made great strides to map brain regions and allocate specific functions to them. Electrical recordings and lesioning studies have been essential for this task. However, most lesioning methods destroy areas larger than intended and may unintentionally remove connecting pathways between other distant regions. They also don’t give any clues about the types of neurons involved or whether their involvement is activating, inhibiting, or modulating. Viral vectors, in contrast, are considerably more versatile and specific in how they manipulate neuronal function, with far fewer side effects compared to lesioning methods -  they may be the key to further unraveling the mysteries of behavior.

New and Upcoming Viral Vectors - September 2019

Posted by Leila Haery on Sep 12, 2019 9:00:49 AM

Since the beginning of our viral service in 2016, we’ve added many new tools to our inventory of ready-to-use viral vectors. Here are some of the AAV we have released in the last few months. You can also browse our entire AAV inventory.

Our new AAVs include:

  • EGFP-expressing AAV for serotype testing
  • Calcium sensors and GABA sensors
  • Optogenetics
  • Recombinases
  • And more!
