Odor coding in the mammalian olfactory epithelium [PDF]

open access: yesCell and Tissue Research, 2020
Noses are extremely sophisticated chemical detectors allowing animals to use scents to interpret and navigate their environments. Odor detection starts with the activation of odorant receptors (ORs), expressed in mature olfactory sensory neurons (OSNs ...

Olfactory epithelium changes in germfree mice [PDF]

open access: yesScientific Reports, 2016
Intestinal epithelium development is dramatically impaired in germfree rodents, but the consequences of the absence of microbiota have been overlooked in other epithelia. In the present study, we present the first description of the bacterial communities

Deconstructing Olfactory Epithelium Developmental Pathways in Olfactory Neuroblastoma. [PDF]

open access: yesCancer Res Commun, 2023
Olfactory neuroblastoma is a rare tumor arising from the olfactory cleft region of the nasal cavity. Because of the low incidence of this tumor, as well as an absence of established cell lines and murine models, understanding the mechanisms driving olfactory neuroblastoma pathobiology has been challenging.

COVID-19-related anosmia is associated with viral persistence and inflammation in human olfactory epithelium and brain infection in hamsters

open access: yesScience Translational Medicine, 2021
SARS-CoV-2 infects the olfactory epithelium of hamsters and humans and persists in it in individuals with COVID-19 for several months after infection.

Olfactory adaptation: recordings from the human olfactory epithelium. [PDF]

open access: yesEur Arch Otorhinolaryngol, 2022
Abstract Purpose Olfactory adaptation is a peripheral (at the epithelium level) or a central (at the brain level) mechanism resulting from repeated or prolonged odorous exposure that can induce a perceptual decrease. The aim of this study was to assess whether a peripheral adaptation occurs when an odor is repeated ten ...

Integrated age‐related immunohistological changes occur in human olfactory epithelium and olfactory bulb

open access: yesThe Journal of comparative neurology, 2022
Olfactory epithelium (OE) is capable of lifelong regeneration due to presence of basal progenitor cells that respond to injury or neuronal loss with increased activity.

Modulation of olfactory signal detection in the olfactory epithelium: focus on the internal and external environment, and the emerging role of the immune system

open access: yesCell and Tissue Research, 2021
Detection and discrimination of odorants by the olfactory system plays a pivotal role in animal survival. Olfactory-based behaviors must be adapted to an ever-changing environment.

Influence of olfactory epithelium on mitral/tufted cell dendritic outgrowth. [PDF]

open access: yesPLoS ONE, 2008
Stereotypical connections between olfactory sensory neuron axons and mitral cell dendrites in the olfactory bulb establish the first synaptic relay for olfactory perception.
