However, we demonstrated that there is in fact a compromise in the conversion of proNGF to biologically active mNGF as well as a likely exacerbated degradation of mNGF (Bruno et al., 2009a), therefore explaining that a trophic failure is responsible for the cholinergic atrophy in AD. Recent observations note that long term treatment with donepezil, one of the leading acetylcholine esterase inhibitors (AChEis) (elevating the “cholinergic tone”) used for its symptomatic cognitive benefits in AD, was shown to reduce the rate of change in regional cortical thickness in individuals suspected of prodromal AD (Cavedo et al., 2016) as well as diminish the rate of hippocampal (Dubois et al., 2015) and BF atrophy in prodromal AD (Cavedo et al., 2017). Such strong experimental evidence provoked a number of clinical attempts to apply exogenous mNGF in the cerebroventricular space of AD patients (Jönhagen et al., 1998), attempts which were discontinued due to adverse off-target effects, specifically the induction of back pain by the sprouting of pain-conducting fibers in the spinal cord dorsal root ganglia. J. Neurosci. doi: 10.1016/S0169-328X(98)00215-0, Rafii, M. S., Baumann, T. L., Bakay, R. A., Ostrove, J. M., Siffert, J., Fleisher, A. S., et al. What are biochemical reactions? The master or central clock located within the suprachiasmatic nucleus in the hypothalamus governs peripheral clocks present in all systemic tissues, contributing to their alignment and ultimately to temporal coordination of physiology. Exp. (2015). Encapsulated cell biodelivery of nerve growth factor to the basal forebrain in patients with Alzheimer’s disease. However, paradoxically, it was shown that NGF mRNA is unchanged in AD (Goedert et al., 1986), and that NGF immunoreactivity is elevated (Crutcher et al., 1993; Scott et al., 1995; Fahnestock et al., 1996). doi: 10.1007/BF02757946, Cuello, A., Stephens, P., Tagari, P., Sofroniew, M., and Pearson, R. (1986). 11, 551–555. Ther. Nerve growth factor increases choline acetyltransferase activity in developing basal forebrain neurons. No use, distribution or reproduction is permitted which does not comply with these terms. These processes are important for normal physiology, so it is not surprising that disease states result from major alterations in their function, but whether relatively minor perturbations of this metabolism contribute to neurodegeneration requires further study… This is a list of some metabolic pathways that genes that the BMRB and PDB have spectroscopy data on.

Among such studies, AIRC researchers are using hyperpolarized 13C pyruvate to study flux through metabolic pathways in cancer cells (Matthew Merritt, Neil Rofsky, Dean Sherry,) and heart muscle (Sherry, Craig Malloy). doi: 10.1006/exnr.1994.1024. It discusses the existence of a metabolic pathway explaining the release of the NGF precursor molecule and its maturation and degradation in the extracellular space. Most recently, attempts to apply NGF therapeutically in the context of AD have employed gene therapy to overexpress the NGF gene (Tuszynski et al., 2005, 2015; Rafii et al., 2014) or the implantation of microencapsulated patient-derived fibroblasts, genetically engineered to overproduce NGF (Eriksdotter-Jönhagen et al., 2012; Eyjolfsdottir et al., 2016).

These results have been further reviewed in (Iulita and Cuello, 2016; Iulita et al., 2016a). It is remarkable, given the widespread and irreversible brain damage already present at AD clinical presentation, that cholinergic therapy can still exert these beneficial cognitive effects.
