GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]

open access: yes, 2001
Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...

Biological Functions of Keratinocyte Cholinergic Receptors

open access: yesJournal of Investigative Dermatology Symposium Proceedings, 1997
Human epidermal keratinocytes possess cholinergic enzymes, which synthesize and degrade acetylcholine, and express both nicotinic and muscarinic classes of cholinergic receptors on their cell surfaces. These receptors bind acetylcholine and initiate cellular response.

Dual role of α7 nicotinic acetylcholine receptors in the retrosplenial cortex for aversive memory acquisition and retrieval

open access: yesFrontiers in Behavioral Neuroscience
In the retrosplenial cortex (RSC), the role of cholinergic modulation via α7 nicotinic receptors and their involvement in memory is unknown. In recent years, the RSC has been shown to deteriorate in the early stages of Alzheimer’s disease (AD). Likewise,
