Extracellular levels of the sleep homeostasis mediator, adenosine, are regulated by glutamatergic neurons during wakefulness and sleep
Sun MJ, Tang Y (2020) Extracellular levels of the sleep homeostasis mediator, adenosine, are regulated by glutamatergic neurons during wakefulness and sleep. Purinergic Signal 16(4):475-476. doi: 10.1007/s11302-020-09758-3
Summary: Blanco-Centurion et al. investigated the role of cholinergic neurons in the BF by administering 192–IgG–SAP to lesion them, but surprisingly the results indicated that adenosine from cholinergic neurons in BF are not essential to sleep induction.

Reversal of object recognition memory deficit in perirhinal cortex-lesioned rats and primates and in rodent models of aging and alzheimer’s diseases.
Masmudi-Martín M, Navarro-Lobato I, López-Aranda MF, Browning PGF, Simón A-M, López-Téllez JF, Jiménez-Recuerda I, Martîn-Montañez E, Pérez-Mediavilla A, Frechilla D, Baxter MG, Khan ZU (2020) 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.

Long-term potentiation in the hippocampal CA3 to CA1 synapses may be induced in vivo by activation of septal cholinergic inputs.
Dobryakova YV, Stepanichev MY, Markevich VA, Bolshakov AP (2020) Long-term potentiation in the hippocampal CA3 to CA1 synapses may be induced in vivo by activation of septal cholinergic inputs. Int J Neurosci 23:1-7. doi: 10.1080/00207454.2020.1822834
Objective: To clarify the role of septal input in the development of long-term potentiation (LTP) in this synapse.
Summary: Elimination of septal cholinergic neurons by 192-IgG-SAP abolished LTP development in both experimental series. This suppression of LTP in animals with a cholinergic deficit was not due to loss of hippocampal neurons.
Usage: Rats received intraseptal injections of 192-IgG-SAP (1.5 μg).

Summary: Highly glucose-sensitive cells in the ventrolateral medulla send catecholaminergic projections to the PVH. These projections can be selectively destroyed by Anti-DBH-SAP “DSAP” experiments show that catecholaminergic projections from glucose-sensitive cells in the ventrolateral medulla are necessary for all responses to glucoprivation, including increases in epinephrine secretion, glucocorticoid secretion, sex behavior, and food intake.
