Towards astroglia-based noradrenergic hypothesis of Alzheimer’s disease
Leanza G, Zorec R (2023) Towards astroglia-based noradrenergic hypothesis of Alzheimer’s disease. Function (Oxf) 4(1):zqac060., IT. doi: 10.1093/function/zqac060 PMID: 36590326
Summary: These results indicate a prominent role of NA-neurons vs. ACh neurons in impairments of working memory, relevant for AD, and are consistent with an astrocyte-specific metabolic impairment in a mouse model of intellectual disability.
Usage: Bilateral icv injection of 192-IgG-SAP and/or Anti-DBH-SAP

Overexpression of nerve growth factor in the hippocampus induces behavioral changes in rats with 192IgG-saporin-induced cholinergic deficit
Dobryakova YV, Zaichenko MI, Spivak YS, Stepanichev MY, Markevich VA, Bolshakov AP (2021) Overexpression of nerve growth factor in the hippocampus induces behavioral changes in rats with 192IgG-saporin-induced cholinergic deficit. Neurochem J 15:273-281. doi: 10.1134/S1819712421030028
Summary: Degeneration of septal cholinergic neurons caused by the immunotoxin 192-IgG-SAP produces a model of the pathological state that occurs in Alzheimer’s Disease. This study investigated whether overexpression of NGF in the hippocampus, where septal neurons send their projections, may reduce the consequences of this damage. Data suggest that NGF overexpression in the hippocampus of rats may partly compensate some 192 IgG-SAP-induced impairments related to cholinergic deficit.
Usage: 192-IgG-SAP or an equivalent volume of PBS (4 µg/site) was administered bilaterally into the ventricles.

Cholinergic modulation of sensory processing in awake mouse cortex

Objective: To decipher the timing and significance of acetylcholine actions.
Summary: Study provides new insights into how the cortex processes sensory information and how loss of acetylcholine, for example in Alzheimer’s Disease, disrupts sensory behaviours.
Usage: Focal cortical injection of mu p75-SAP or Rabbit IgG-SAP (1.7 mg/ml, 0.3 µl total volume, rate 0.075 µl/minute).

Neurotoxic effects, mechanisms, and outcome of 192 IgG-Saporin lesions.
Petrosini L, De Bartolo P, Cutuli D (2021) Neurotoxic effects, mechanisms, and outcome of 192 IgG-Saporin lesions. RM Kostrzewa (Ed.): Handbook of Neurotoxicity . Springer, Cham doi: 10.1007/978-3-030-71519-9_79-1
Summary: 192-IgG-saporin selectively destroys basal forebrain cholinergic neurons that provide cholinergic input to the hippocampus, entire cortical mantle, amygdala, and olfactory bulb. Immunotoxic lesions by 192-IgG-saporin represent a valid animal model of Alzheimer’s disease, given the degeneration of basal cholinergic system present in this pathology. The selective lesioning of cholinergic innervation by means of 192-IgG-saporin (injected i.p. or i.c.v.) is able to interfere with experience-dependent plasticity.

Reversal of object recognition memory deficit in perirhinal cortex-lesioned rats and primates and in rodent models of aging and alzheimer’s diseases.

Neuroscience 448:287-298. doi: 10.1016/j.neuroscience.2020.08.039
Objective: To determine if Object Recognition Memory (ORM) can be restored.
Summary: Memory-deficient rats were generated by induction of lesions to the perirhinal cortex (PRh) through an injection of OX7-SAP. Expression of regulator of G-protein signaling 14 of 414 amino acids (RGS14414) restored ORM in memory-deficient PRh-lesioned rats and nonhuman primates. This treatment was sufficient for full recovery of ORM in rodent models of aging and Alzheimer’s disease.
Usage: Rats were injected with OX7-SAP (0.9 mg in 1ml) in the PRh of the brain.
