Abstract Neuropeptide Y (NPY) recognition by the human neuroblastoma cell lines SiMa, Kelly, SH‐SY5Y, CHP‐234, and MHH‐NB‐11 was analyzed in radioactive binding assays using tritiated NPY. For the cell lines CHP‐234 and MHH‐NB‐11 binding of [3H]propionyl‐NPY was observed with Kd‐values of 0.64 ± 0.07 nM and 0.53 ± 0.12 nM, respectively, determined by saturation analysis with non‐linear regression. The receptor subtype was determined by competition analysis using the subtype selective NPY analogues [Leu31, Pro34]‐NPY (NPY‐Y1, NPY‐Y5), [Ahx5‐24]‐NPY (NPY‐Y2), [Ala31, Aib32]‐NPY (NPY‐Y5), NPY [3‐36] (NPY‐Y2, NPY‐Y5), and NPY [13‐36] (NPY‐Y2). Both cell lines, CHP‐234 and MHH‐NB‐11, the latter one being characterized for NPY receptors for the first time, showed exclusive expression of NPY‐Y2 receptors. In both cell lines binding of NPY induced signal transduction, which was monitored as reduction of forskolin‐induced cAMP production in an ELISA.
