Single-Cell Transcriptomes Reveal a Complex Cellular Landscape in the Middle Ear and Differential Capacities for Acute Response to Infection. [PDF]

open access: yes, 2020
Single-cell transcriptomics was used to profile cells of the normal murine middle ear. Clustering analysis of 6770 transcriptomes identified 17 cell clusters corresponding to distinct cell types: five epithelial, three stromal, three lymphocyte, two ...

Immunohistochemical localization of d‐β‐aspartic acid in congenital and acquired middle ear cholesteatoma

open access: yesLaryngoscope Investigative Otolaryngology, 2022
Objective/Hypothesis Middle ear cholesteatoma is characterized by abnormal growth of the keratinizing squamous epithelium of the temporal bone. d‐β‐aspartic acid is the major isomer of d‐aspartic acid found in elderly tissue.

Cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission

open access: yes, 2014
A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and induces a pressure difference across the membrane.

THE PHYSIOLOGY OF THE MIDDLE EAR. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1904
The scope of this paper embraces the following parts: 1, the drum cavity; 2, the attic; 3, the aditus ad antrum; 4, the mastoid antrum; 5, the mastoid cells; 6, the eustachian tube. The function of the eustachian tube is, first, to ventilate the middle ear, and secondly, to drain the secretions from the middle ear into the nasopharynx.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
