Data taken from human brain protein atlas using FANTOM5 dataset and Cap Analysis of Gene Expression (CAGE). Data can be found in https://www.proteinatlas.org/search/adenosine+receptor (Accessed on 12 April 2021). For each receptor, a color scale shows higher (darker) versus lower (lighter) expression; the highest expression level for each receptor is underlined.
