Strong stimulation triggers full fusion exocytosis and very slow endocytosis of the small dense core granules in carotid glomus cells.

J Neurogenet 2018 Sep;32(3):267-278

a Department of Pharmacology and Neuroscience and Metal Health Institute , University of Alberta , Edmonton , Canada.

Chemosensory glomus cells of the carotid bodies release transmitters, including ATP and dopamine mainly via the exocytosis of small dense core granules (SDCGs, vesicular diameter of ∼100 nm). Using carbon-fiber amperometry, we showed previously that with a modest uniform elevation in cytosolic Ca concentration ([Ca] of ∼0.5 µM), SDCGs of rat glomus cells predominantly underwent a "kiss-and-run" mode of exocytosis.

Genome and evolution of the arbuscular mycorrhizal fungus Diversispora epigaea (formerly Glomus versiforme) and its bacterial endosymbionts.

New Phytol 2018 Oct 13. Epub 2018 Oct 13.

Boyce Thompson Institute, Ithaca, NY, 14853, USA.

Arbuscular mycorrhizal (AM) fungi form endosymbioses with most plants, and they themselves are hosts for Mollicutes/Mycoplasma-related endobacteria (MRE). Despite their significance, genomic information for AM fungi and their MRE are relatively sparse, which hinders our understanding of their biology and evolution. We assembled the genomes of the AM fungus Diversispora epigaea (formerly Glomus versiforme) and its MRE and performed comparative genomics and evolutionary analyses. Read More

Molecular Characterization of Equilibrative Nucleoside Transporters in the Rat Carotid Body and Their Regulation by Chronic Hypoxia.

Adv Exp Med Biol 2018 ;1071:43-50

Department of Biology, McMaster University, Hamilton, ON, Canada.

The mammalian carotid body (CB) is the main peripheral arterial chemoreceptor organ that is excited by decreases in blood PO (hypoxia) and increases in blood PCO/H. An increase in CB afferent carotid sinus nerve (CSN) discharge results in respiratory and cardiovascular reflex responses that help maintain homeostasis. The CB consists mainly of innervated clusters of the chemoreceptive type I (glomus) cells that are associated with the processes of glial-like type II cells. Read More

TASK-1 (K3) and TASK-3 (K9) in Rabbit Carotid Body Glomus Cells.

Adv Exp Med Biol 2018 ;1071:35-41

Department of Physiology and Biophysics, Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, IL, USA.

Glomus cells isolated from rabbit and rat/mouse carotid bodies have been used for many years to study the role of ion channels in hypoxia sensing. Studies show that hypoxia inhibits the inactivating K channels (Kv4) in rabbits, but inhibits TASK in rats/mice to elicit the hypoxic response. Because the role of TASK in rabbit glomus cells is not known, we isolated glomus cells from rabbits and studied the expression of TASK mRNA in the whole carotid body (CB), changes in [Ca] and TASK activity.

Universitätsklinik und Poliklinik für Viszerale, Gefäß und Endokrine Chirurgie, Martin-Luther-Universität Halle-Wittenberg, Ernst-Grube-Str. 40, 06120, Halle/Saale, Deutschland.

The therapies available for the rare tumor entity of cervical paraganglioma (PG) are currently undergoing a paradigm shift. The treatment of choice for small carotid body tumors, malignant and active endocrine tumors is surgical resection; however, for locally advanced carotid body tumors and vagal PG, surgical therapy should be critically evaluated. Due to the immediate proximity of these hypervascularized tumors to the caudal cranial nerves, there is a risk of severe nerve damage with a significant impairment of quality of life after resection, particularly for locally advanced cervical PG, emphasizing further the importance of a restrictive surgical strategy.

Stereotactic radiosurgery for hypervascular intracranial tumors.

J Neurooncol 2018 Dec 20;140(3):547-558. Epub 2018 Aug 20.

Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, 17F, No. 201, Shih-Pai Road, Sec. 2, Beitou, Taipei, 11217, Taiwan, ROC.

Objective: To evaluate the safety and efficacy of SRS treatment of central neurocytomas (CNCs), cavernous sinus hemangiomas (CSHs), and glomus tumors (GTs); and to compare upfront stereotactic radiosurgery (SRS) and adjuvant SRS in the treatment of these hypervascular tumors.

Methods: This was a retrospective review of consecutive CNCs, CSHs, and GTs treated with SRS between 1993 and 2017. Tumor response was categorized based on volumetric analysis on magnetic resonance imaging: (1) tumor regression [> 10% decrease in tumor volume (TV)]; (2) stable tumor (≤ 10% change in TV); or (3) tumor progression (> 10% increase in TV).

Community composition of arbuscular mycorrhizal fungi associated with native plants growing in a petroleum-polluted soil of the Amazon region of Ecuador.

Microbiologyopen 2018 Aug 16:e00703. Epub 2018 Aug 16.

Laboratory of Mycology, Earth and Life Institute, Université catholique de Louvain, Louvain-la-Neuve, Belgium.

Arbuscular mycorrhizal fungi (AMF) are worldwide distributed plant symbionts. However, their occurrence in hydrocarbon-polluted environments is less investigated, although specific communities may be present with possible interest for remediation strategies. Here, we investigated the AMF community composition associated with the roots of diverse plant species naturally recolonizing a weathered crude oil pond in the Amazon region of Ecuador. Read More

Plant host habitat and root exudates shape fungal diversity.

Mycorrhiza 2018 Aug 15;28(5-6):451-463. Epub 2018 Aug 15.

CNRS, UMR5557, Ecologie Microbienne, INRA, UMR1418, Université Lyon 1, 69220, Villeurbanne Cedex, France.

The rhizospheric microbiome is clearly affected by plant species and certain of their functional traits. These functional traits allow plants to adapt to their environmental conditions by acquiring or conserving nutrients, thus defining different ecological resource-use plant strategies. In the present study, we investigated whether plants with one of the two nutrient-use strategies (conservative versus exploitative) could influence fungal communities involved in soil organic matter degradation and root exudate assimilation, as well as those colonizing root tissues.
