Figure 6. Model of signaling events leading to homologous and heterologous desensitization in adipocytes.

Figure 6

Both homologous (β3-AR activation dependent) and heterologous (TNF-α dependent) desensitization of β3-AR converge through activation of EPAC/RAP2A/PI-PLC–dependent Ca2+–stimulated induction of Trib1, which in turn leads to the degradation of CEBPα and downregulation of Adrb3/β3-AR.
