CD120

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

Receptor subtypes

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]
