CD120 (C luster of D ifferentiation 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
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]
