Bioinformatics approach reveals Nur77-regulated genes common to the central nervous and immune systems

Neurons and immune cells have similar mechanisms for cell to cell communication. Exists active crosstalk between neurons and immune cells. Neurotransmitters can activate or inhibit immune cells, and cytokines modulate neuronal activity. The transcription factor Nur77 (NR4A1) is highly and transiently induced by several stimuli in neurons and T-lymphocytes, suggesting that Nur77 is involved in the coordination of the genetics response in both cell types. By analyzing publicly available databases, we found Nur77 target genes common to the nervous and immune systems. Functions as cell adhesion and anchoring appear as processes regulated by Nur77 in neurons and immune cells.
