This was a really fun project I worked on with a friend who is a scientist at The University of Pennsylvania and specializes in the research of Alzheimer's disease. The illustration was commissioned to accompany new research based on an antibody that can search out specific protein tangles that are found in patients with Alzheimer's. The concept was to show the antibody's unique ability to single out these proteins in the diseased neurons. The illustration is also featured as the cover of the March 2018 Journal of Neuropathology and Experimental Neurology. I've included some process photos which show the concept and color sketches that were done in preparation for the final illustration.
