Calcitonin gene-related peptide (CGRP) is a 37-amino acid neuropeptide that functions in pain signaling and neuroimmune communication. The CGRP receptor, CGRPR, is a class B GPCR that is a drug target for migraine headache and other disorders. Here, we used nanoBRET receptor binding and cAMP biosensor signaling assays and theoretical modeling to characterize the CGRPR "two-domain" peptide binding mechanism. Single-site extracellular domain (ECD)-binding and two-site ECD/transmembrane domain...

Both type 1 and type 2 diabetes mellitus (T1D and T2D) are associated with poor bone health and an increased risk of fracture in adults. However, there are limited data regarding the effects of diabetes on the growing skeleton, particularly during adolescence, the time of peak bone mineral accretion. The purpose of this study was to examine differences in markers of bone health and factors that influence bone health in White adolescents and young adults with well-controlled T1D (n = 17; Average...

Iatrogenic injury to the temporal branches of the facial nerve (CN VII) is the leading postoperative complication of the preauricular surgical approach to the temporomandibular joint (TMJ). Many of the anatomical illustrations vary greatly in how the anatomy of the temporal branches of the facial nerve are depicted. Additionally, there are few studies that discuss this variation. This study aims to provide more accurate data on this discrepancy. Here, the distribution of temporal branches of the...

Agriculture and food security face significant challenges due to population growth, climate change, and biotic and abiotic stresses. Enhancing crop productivity and quality through biotechnology is crucial in addressing these challenges. Genome engineering techniques, including gene cassette delivery into plant cells, aim to meet these demands. However, conventional biomolecule delivery methods have limitations such as poor efficacy, low regeneration capability, and potential cell damage....
