protein-coupled receptors (GPCRs) are membrane-bound proteins that sense external stimuli and relay signals For example, dimerization has been shown to affect signaling pathways in class A dopamine receptors like homodimers and heterodimers, which may play a crucial role in modulating receptor function and ligand signaling decreased high-affinity binding to its natural ligand, GLP-1, while selectively affecting receptor signaling Perreault, M.L., et al., Heteromeric dopamine receptor signaling complexes: emerging neurobiology and

October 2022 "Alzheimer's disease (AD) is the most common dementia in the elderly and its increasing prevalence presents treatment challenges. Despite a better understanding of the disease, the current mainstay of treatment cannot modify pathogenesis or effectively address the associated cognitive and memory deficits. Emerging evidence suggests adenosine G protein-coupled receptors (GPCRs) are promising therapeutic targets for Alzheimer's disease. The adenosine A1 and A2A receptors are expressed in the human brain and have a proposed involvement in the pathogenesis of dementia. Targeting these receptors preclinically can mitigate pathogenic β-amyloid and tau neurotoxicity whilst improving cognition and memory. In this review, we provide an accessible summary of the literature on Alzheimer's disease and the therapeutic potential of A1 and A2A receptors. Although there are no available medicines targeting these receptors approved for treating dementia, we provide insights into some novel strategies, including allosterism and the targeting of oligomers, which may increase drug discovery success and enhance the therapeutic response."
