Dr. Paul F. Worley is a professor of neuroscience at the Johns Hopkins University School of Medicine. An expert in the molecular basis of specific forms of long-term learning and memory, Dr. Worley serves on the faculty of the Institute for Basic Biomedical Sciences and as an associated investigator with the Alzheimer’s Disease Research Center.
Dr. Worley’s laboratory focuses on a class of proteins found at the interfaces of connecting neurons (synapses) that ramp up as the neurons engage in information processing and storage. These proteins directly modify the strength of the signals sent between neurons and are essential for information storage.
Recent work reveals how molecules that regulate reward-signaling neuronal responses (such as dopamine) can selectively strengthen communication across synapses – and implicates this process in addiction.
Dr. Worley’s research also has clinical potential in the treatment of patients with degenerative memory conditions such as Alzheimer’s disease.

Research & Publications
Dr. Worley’s laboratory examines the molecular basis of learning and memory.
In particular, research in the Worley Lab have cloned a set of immediate early genes (IEGs) that are rapidly transcribed in neurons involved in information processing, and that are essential for long-term memory.
IEG proteins can directly modify synapses and provide insight into cellular mechanisms that support synapse-specific plasticity.
For example, Narp is secreted and induces excitatory synapse formation. Homer catalyzes conformational coupling of multi-protein machines involved in calcium signaling. Rheb regulates mTor (target of rapamycin) and protein translation. Arc induces the formation of endosomes that function in trafficking of glutamate receptors.
Thus, rapid de novo transcription provides novel insights into the cellular and neural network basis of behavioral plasticity.
