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).

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

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