A modiolar-pillar gradient in auditory-nerve dendritic length: A novel post-synaptic contribution to dynamic range?

Hear Res

December 2024

Eaton-Peabody Laboratories, Massachusetts Eye and Ear, Boston, MA, United States; Department of Otolaryngology-Head & Neck Surgery, Harvard Medical School, Boston, MA, United States. Electronic address:

Auditory-nerve fibers (ANFs) from a given cochlear region can vary in threshold sensitivity by up to 60 dB, corresponding to a 1000-fold difference in stimulus level, although each fiber innervates a single inner hair cell (IHC) via a single synapse. ANFs with high-thresholds also have low spontaneous rates (SRs) and synapse on the side of the IHC closer to the modiolus, whereas the low-threshold, high-SR fibers synapse on the side closer to the pillar cells. Prior biophysical work has identified modiolar-pillar differences in both pre- and post-synaptic properties, but a comprehensive explanation for the wide range of sensitivities remains elusive.

Immune exclusion inhibits anti-tumor immunity and response to immunotherapy, but its mechanisms remain poorly defined. Here, we demonstrate that Trophoblast Cell-Surface Antigen 2 (TROP2), a key target of emerging anti-cancer Antibody Drug Conjugates (ADCs), controls barrier-mediated immune exclusion in Triple-Negative Breast Cancer (TNBC) through Claudin 7 association and tight junction regulation. TROP2 expression is inversely correlated with T cell infiltration and strongly associated with outcomes in TNBC.

Characterizing Vocal Hyperfunction Using Ecological Momentary Assessment of Relative Fundamental Frequency.

J Voice

December 2024

Speech and Hearing Bioscience and Technology Program, Harvard University, 25 Shattuck St, Boston 02115, Massachusetts; Harvard Medical School, 25 Shattuck St, Boston 02115, Massachusetts; Mass General Hospital (MGH) Voice Center, 1 Bowdoin Sq, Boston 02114, Massachusetts; MGH Institute of Health Professions, 36 1st Ave, Boston 02129, Massachusetts. Electronic address:

Many common voice disorders are associated with vocal hyperfunction (VH), with subtypes including phonotraumatic VH (leading to organic vocal fold lesions such as nodules and/or polyps) and nonphonotraumatic VH (often diagnosed as primary muscle tension dysphonia). VH has been hypothesized to influence baseline vocal fold tension during phonation, and the relative fundamental frequency (RFF) during onset and offset cycles of phonation has been related to vocal fold tension and has been shown to differentiate typical voices from patients with VH in laboratory settings. In this study, we investigated whether the laboratory sensitivity of RFF to the presence of VH found in the laboratory is preserved in naturalistic, in-field settings and whether ecological momentary assessment of RFF during daily life could be a correlate of self-reported vocal effort.
