Visualizing in deceased COVID-19 patients how SARS-CoV-2 attacks the respiratory and olfactory mucosae but spares the olfactory bulb

open access: yesCell, 2021
Anosmia, the loss of smell, is a common and often the sole symptom of COVID-19. The onset of the sequence of pathobiological events leading to olfactory dysfunction remains obscure.

Olfactory coding

Current Biology, 2022
Modern humans live in real and digital environments dominated by sight and sound, but the vast majority of organisms on the planet rely on information received through air- or water-borne molecules to find food, avoid danger, and reproduce. Olfaction is at once both the primitive sensory modality and one of the hardest to understand, in large part due ...

Olfactory Neuroblastoma

Acta Oto-Laryngologica, 1975
A case of olfactory neuroblastoma, type 1 (olfactory neurocytoma), in a 44-year-old man is described. The tumour grew extensively in the right nasal cavity with involvement of the maxillary sinus and ethmoidal region, but was radically removed at operation. The prognosis and treatment are discussed in the light of earlier literature.

Olfactory receptors

Cellular and Molecular Life Sciences (CMLS), 2004
Olfaction is an ancient sensory system allowing an organism to detect chemicals in its environment. The first step in odor transduction is mediated by binding odorants to olfactory receptors (ORs) which belong to the heptahelical G-protein-coupled receptor (GPCR) superfamily. Mammalian ORs are disposed in clusters on virtually all chromosomes. They are

Olfactory schwannoma

Acta Neurochirurgica, 2007
We report a case of olfactory schwannoma with calcification. Intraoperative findings indicated that the tumour originated from the olfactory groove. Intraoperative findings of previous studies have not indicated a clear relationship between subfrontal schwannoma and the olfactory nerve, which seems strange, given the association between tumours and ...

Olfactory Neuroblastoma

Otolaryngology–Head and Neck Surgery, 1979
Olfactory neuroblastoma is an uncommon malignant tumor arising from olfactory epithelium. Generally considered to be a tumor of slow growth, it varies in aggressiveness and may cause death by distant metastasis or local invasion. The pathologic diagnosis is difficult, and this tumor is often erroneously diagnosed.Nine previously unreported cases are ...
