We present the nucleotide (nt) sequence for the cDNA encoding bovine brain-derived neurotrophic factor (BDNF). The nt and peptide sequences were compared to those of other BDNF genes from other species.
We have studied the postnatal expression of neurotrophins, their cognate high-affinity trk receptors and the low-affinity NGF receptor (p75LNGFR) in the rat adrenal gland using RT-PCR. Neurotrophin mRNAs were detectable during the whole postnatal period. Strongest signals were obtained for BDNF and NT4/5. Expression of trkA, trkB, trkC and p75LNGFR was found at all ages studied. Signals for trkA were highest in the adult adrenal medulla, whereas signals for p75LNGFR were highest in the adult adrenal cortex. Cur data suggest still largely enigmatic roles for neurotrophins in functions of the adrenal medulla and possibly also the cortex.
