Cholinergic regulation of adult hippocampal neurogenesis and hippocampus-dependent functions

Madrid LI, Jimenez-Martin J, Coulson EJ, Jhaveri DJ (2021) Cholinergic regulation of adult hippocampal neurogenesis and hippocampus-dependent functions. Int J Biochem Cell Biol 134:105969. doi: 10.1016/j.biocel.2021.105969

Summary: In this review, the authors appraise the evidence linking the contribution of cholinergic signalling to the regulation of adult hippocampal neurogenesis and hippocampus-dependent functions.

Usage: A hallmark feature of all basal forebrain cholinergic neurons is the expression of high levels of the p75 neurotrophin receptor which can be precisely targeted using 192-IgG-SAP. Administration of 192-IgG-SAP (icv, 2.5 µg, Mohapel et al., 2005) resulted in significant impairment in adult hippocampal neurogenesis in rats. In contrast, a study which lesioned MS cholinergic neurons in mice reported no effect on baseline proliferation in the hippocampus. Mice received 3.6 µg of mu p75-SAP into each lateral ventricle (Ho et al., 2009). Although the number of surviving neurons was similar in both lesioned and control animals, most of the progenitor cells in the lesioned animals could not survive without cholinergic input.
