Background Hereditary cystic kidney diseases such as nephronophthisis, polycystic kidney disease and Bardet-Biedl syndrome (BBS) are caused by a dysfunction of primary cilia. Cilia are involved in a ...

An analysis olfactory epithelium with a biopsy-like approach found that COVID-19 patients with a prolonged loss of smell may have their nerve cells fallen victim to T cells.

The olfactory epithelium covers the inferior portion of the cribriform plate (part of the ethmoid bone) and is where the olfactory receptor neurons (ORNs) are located. These ORNs are responsible for ...

Interestingly, the respiratory epithelium within the olfactory cleft region is constituted by several cell populations, including secretory cells, ciliated cells, basal cells, submucosal Bowman ...

Olfactory sensory neurons (OSNs) in vertebrates detect odorants using multiple cilia, which protrude from the end of the dendrite and require centrioles for their formation. In mouse olfactory ...

Nevertheless, two specific cell types in the olfactory epithelium expressed ACE2 at similar levels to what has been observed in the lower respiratory tract cells. These included sustentacular cells, ...
