Platelet-Activating Factor (PAF) Receptor in Brain and Signal Transduction in Neurons
Specific, reversible and saturable binding sites for [3H]-PAF were observed in gerbil brain. Scatchard analysis revealed the existence of two apparent classes of binding sites with Kd1=3.7 nM and Kd2=20.4 nM. The maximal density of binding sites was found in midbrain and hippocampus (Domingo et al., 1988). The existence of specific binding sites for PAF was also shown in rat hypothalamus (Junier et al., 1988) and synaptosomes and microsomal fractions of rat cerebral cortex (Marcheselli et al., 1990).
