Bradykinin was found to bind to specific high-affinity sites in cultured cortical astrocytes from rat brain, and this binding appeared to be specific for the B2 bradykinin receptor subtype. Nonlinear regression analysis of saturation experiments using a computer programme revealed a single KD of 16.6 ± 2.6 nM and a Bmax of 352.2 ±30.7 fmol/mg of protein. These results indicate that astrocytes possess bradykinin receptors and that these are predominantly of the B2 subtype.
