Odorant receptor co-receptors affect expression of tuning receptors in Drosophila

Frontiers in Cellular Neuroscience
Insects detect odorants using two large families of heteromeric receptors, the Odorant Receptors (ORs) and Ionotropic Receptors (IRs). Most OR and IR genes encode odorant-binding “tuning” subunits, whereas four (Orco, Ir8a, Ir25a, and Ir76b) encode co ...

Mesenchymal Stem Cell‐Derived Apoptotic Micro‐Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis

Advanced Healthcare Materials, EarlyView.
HUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

Dysregulation of Olfactory Receptor Neuron Lineage in Schizophrenia [PDF]

Archives of General Psychiatry, 2001
Growing evidence implicates abnormal neurodevelopment in schizophrenia. While neuron birth and differentiation is largely completed by the end of gestation, the olfactory epithelium (OE) is a unique part of the central nervous system that undergoes regeneration throughout life, thus offering an opportunity to investigate cellular and molecular events ...

Prion shedding from olfactory neurons into nasal secretions. [PDF]

PLoS Pathogens, 2010
This study investigated the role of prion infection of the olfactory mucosa in the shedding of prion infectivity into nasal secretions. Prion infection with the HY strain of the transmissible mink encephalopathy (TME) agent resulted in a prominent ...

Olfactory sensory neurons transiently express multiple olfactory receptors during development

Molecular Systems Biology, 2015
In mammals, each olfactory sensory neuron randomly expresses one, and only one, olfactory receptor (OR)--a phenomenon called the "one-neuron-one-receptor" rule. Although extensively studied, this rule was never proven for all ~1,000 OR genes in one cell at once, and little is known about its dynamics.
