This review presents information about multiple neurochemical substances in the carotid body. Nerve fibers around blood vessels and glomus cells within the chemoreceptive organ contain immunoreactivities (IR) for tyrosine hydroxylase (TH), calcitonin gene-related peptide (CGRP), substance P (SP), galanin (GAL), vasoactive intestinal polypeptide (VIP), neuropeptide Y (NPY), calretinin (CR), calbindin D-28k (CB), parvalbumin (PV), and nitric oxide synthase (NOS). Parasympathetic neurons scattered around the carotid body contain VIP, choline acetyltransferase, and vanilloid receptor 1-like receptor. In the mammalian carotid body, transection of the carotid sinus nerve (CSN) causes the absence or decrease of CGRP-, SP-, and NOS-immunoreactive (IR) nerve fibers, whereas all NPY-IR nerve fibers disappear after removal of the superior cervical ganglion. Most VIP-IR nerve fibers disappear but a few persist after sympathetic ganglionectomy. In addition, the CSN transection appears to cause the acquisition of GAL-IR in originally immunonegative glomus cells and nerve fibers within the rat carotid body. On the other hand, 4%, 25%, 17%, and less than 1% of petrosal neurons retrogradely labeled from the rat CSN contain TH-, CGRP-, SP-, and VIP-IR, respectively. In the chicken carotid body, many CGRP- and SP-IR nerve fibers disappear after vagus nerve transection or nodose ganglionectomy. GAL-, NPY-, and VIP-IR nerve fibers mostly disappear after removal of the 14th cervical ganglion of the sympathetic trunk. The origin and functional significance of the various neurochemical substances present in the carotid body is discussed. 相似文献

Transit from the nuclear complex to the cytoplasm through the nuclear pore complex permits modification of mRNA, including processing such as splicing, capping, and polyadenylation, etc. At each of these events, mRNA interacts with various proteins to form mRNA‐protein complex. Visualizing the mRNA is crucial for understanding the mechanisms underlying mRNA processing and elucidating its structure and recent advances in mRNA imaging allow detection of real‐time mRNA localization in living cells. However, these techniques revealed only the location of mRNA but cannot visualize the conformation of mRNA‐protein complex in cells. On the other hand, transmission electron microscopy has been used to visualize the structure of the Balbiani ring‐derived large mRNA, but their observations were limited to the insect cells. In this study, we visualized the structure of mRNA‐protein complex in human culture cells by using immuno‐electron microscopy. Through immuno‐detection, an mRNA exon junction binding complex Y14, and its binding protien Upf2, different gold particle patterns were imaged with transmission electron microscopy and analyzed. Characteristic linear and stacked particle orientation were observed. Across the nuclear membrane, only linear aggregation pattern was observed, whereas the stacked aggregation pattern was detected in the cytoplasm. Our method is able to visualize mRNA‐conformation and applicable to many cell types, including mammalian cells, where genes can easily be manipulated. 相似文献
