CD120 (Cluster of Differentiation 120) can refer to two members of the tumor necrosis factor receptor superfamily: tumor necrosis factor receptor 1 (TNFR1) and tumor necrosis factor receptor 2 (TNFR2).[1][2]

Receptor subtypes[edit]

There are two variants of the receptor, each encoded by a separate gene:

  • CD120a - TNFR1 - TNFR superfamily member 1A
  • CD120b - TNFR2 - TNFR superfamily member 1B

TNFR1 is the receptor type responsible for mediation of TNF-alpha induced sickness behavior,[3] and is involved in neurotoxic processes.[4] Elevated levels of TNFR1 has been found in severe mental disorders.[5]

Signaling pathway[edit]
