Nerve growth factor immunoreactivity and sympathetic sprouting in the rat hippocampal formation.

abstract：:A study of brains of 16 dogs from one to 19 years of age showed a structure- and cell-type- specific pattern of tau protein phosphorylation at mAb Tau-1 site and the absence of phosphorylation at the mAb AT8 site. Strong immunolabeling with mAb Tau-1 of the mossy fibers and perikarya of neurons in sectors CA3 and CA4 ...
