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,
and is involved in neurotoxic processes. [3 ] Elevated levels of TNFR1 has been found in severe mental disorders. [4 ] [5 ]
