The current study infused the immunotoxin 192-IgG-Saporin bilaterally into the medial septum to produce selective cholinergic deafferentation of the hippocampal formation. Sexual dimorphism and age are critical factors in the progression of neurodegenerative disorders, yet these factors have not been evaluated in food protection behavior. The role of these fibers in information processing deficits has been debated however, spontaneous behaviors such as food protection have been observed to dissociate the contributions of hippocampal and cortical cholinergic function. Summary: Loss of hippocampal cholinergic projection originating from basal forebrain structures has been associated with the progression of Dementia of the Alzheimer’s Type. Osterlund Oltmanns JR, Schaeffer EA, Blackwell AA, Pietrucha SA, Yang H, Tasi S, Kartje GL, Wallace D (2021) Effects of age on sexually dimorphic food protection behavior associated with hippocampal cholinergic deafferentation. Usage: 1.5 mg of 192-IgG-SAP was injected into the medial septum area.Įffects of age on sexually dimorphic food protection behavior associated with hippocampal cholinergic deafferentation. The authors concluded that NGF overexpression in the hippocampus after cholinergic loss induces beneficiall effects which are not related to maintenance of cholinergic function. Summary: 192-IgG-SAP was used to induce a rat animal model of cholinergic deficit. Objective: Determine any beneficial effects of adeno-associated virus (AAV)-mediated overexpression of nerve growth factor (NGF) in the hippocampus of rats with cholinergic loss. Intrahippocampal adeno-associated virus-mediated overexpression of nerve growth factor reverses 192IgG-saporin-induced impairments of hippocampal plasticity and behaviorĭobryakova YV, Spivak YS, Zaichenko MI, Koryagina AA, Markevich VA, Stepanichev MY, Bolshakov AP (2021) Intrahippocampal adeno-associated virus-mediated overexpression of nerve growth factor reverses 192IgG-saporin-induced impairments of hippocampal plasticity and behavior.

Donepezil plus estradiol treatment enhances learning and delay-dependent memory performance by young ovariectomized rats with partial loss of septal cholinergic neurons. Gibbs RB Basal forebrain cholinergic neurons are necessary for estrogen to enhance acquisition of a delayed matching-to-position T-maze task.Usage: The authors reference a publication about the effects of estrogen on cognitive improvements where 192-IgG-SAP was used as a specific cholinergic system lesioning tool. Summary: This perspective identifies numerous areas for future preclinical and clinical research, highlighting the need for randomized controlled trials in postmenopausal women to assess the impact of choline supplementation on cognitive decline, with appropriate consideration of the estrogen availability, critical windows, dose, and PEMT genotype. Objective: Explore the relationship between cognitive aging and sex hormones, the cholinergic system, and choline as an essential nutrient. Perspective: Estrogen and the risk of cognitive decline: a missing choline(rgic) link?īortz J, Klatt KC, Wallace TC (2021) Perspective: Estrogen and the risk of cognitive decline: a missing choline(rgic) link?.
