|title=Diaphanous 1 ([[DIAPH1]]) is Highly Expressed in the Aged Human Medial Temporal Cortex and Upregulated in Myeloid Cells During Alzheimer's Disease.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/29966194
|abstract=The receptor for advanced glycation end products (RAGE) is linked to cellular stress and inflammation during Alzheimer's disease (AD). RAGE signals through Diaphanous-1 ([[DIAPH1]]); however, the expression of [[DIAPH1]] in the healthy and AD human brain has yet to be methodically addressed. To delineate the cell- and disease-state specific expression of [[DIAPH1]] in the human medial temporal cortex during healthy aging and AD. We used semi-quantitative immunohistochemistry in the human medial temporal cortex paired with widefield and confocal microscopy and automated analyses to determine colocalization and relative expression of [[DIAPH1]] with key cell markers and molecules in the brains of subjects with AD versus age-matched controls. We report robust colocalization of [[DIAPH1]] with myeloid cells and increased expression during AD, which strongly correlated to increased neutral lipids and morphology of inflamed myeloid cells. [[DIAPH1]] moderately colocalized with markers of endothelial cells, astrocytes, neurons, and oligodendrocytes. Our findings localize [[DIAPH1]] particularly to myeloid cells in the CNS, especially in AD in the locations of lipid droplet accumulation, thereby implicating RAGE-[[DIAPH1]] signaling in dysregulated lipid metabolism and morphological changes of inflamed myeloid cells in this disorder.

|title=The multiple faces of RAGE--opportunities for therapeutic intervention in aging and chronic disease.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/26558318
|abstract=This review focuses on the multi-ligand receptor of the immunoglobulin superfamily--receptor for advanced glycation endproducts (RAGE). The accumulation of the multiple ligands of RAGE in cellular stress milieux links RAGE to the pathobiology of chronic disease and natural aging. In this review, we present a discussion on the ligands of RAGE and the implications of these ligand families in disease. We review the recent literature on the role of ligand-RAGE interaction in the consequences of natural aging; the macro- and microvascular complications of diabetes; obesity and insulin resistance; autoimmune disorders and chronic inflammation; and tumors and Alzheimer's disease. We discuss the mechanisms of RAGE signaling through its intracellular binding effector molecule--the formin [[DIAPH1]]. Physicochemical evidence of how the RAGE cytoplasmic domain binds to the FH1 (formin homology 1) domain of [[DIAPH1]], and the consequences thereof, are also reviewed. We discuss the modalities of RAGE antagonism currently in preclinical and clinical studies. Finally, we present the rationale behind potentially targeting the RAGE cytoplasmic domain-[[DIAPH1]] interaction as a logical strategy for therapeutic intervention in the pathological settings of chronic diseases and aging wherein RAGE ligands accumulate and signal.
