Health Focus: Drugs and the Brain

The brain orchestrates everything we do, sending signals through the nervous system to control different parts of our body. The brain is also the home of our thoughts and consciousness, as neurons process the input from our senses and store what they find as memories. Many drugs are available to help tune the function of the brain and nervous system when there are problems. Unfortunately, the effects of some drugs are hard to control and can lead to abuse and addiction. Explore PDB-101 Resources to learn about proteins related to our nervous system and mental health.

Celebrating 50 Years of Protein Data Bank

In 1971, the structural biology community established the single worldwide archive for macromolecular structure data–-the Protein Data Bank (PDB). In 2021, RCSB PDB and wwPDB are celebrating the 50^th Anniversary of the PDB with symposia, materials, and more.

Inaugural PDB50 Virtual Symposium (May 4-5). Register and submit abstracts by March 15^th for reduced rates.
