Abstract
Spiral ganglion neurons (SGN) transmit auditory signals from sensory-receptive hair cells to the cochlear nucleus in the brain. Damage to hair cellstypically leads to degeneration of SGN and represents one of the leading causes of sensorineural hearing loss (SNHL) worldwide. The effectiveness of the most successful auditory prosthetic, the cochlear implant, in treating SNHL depends on the number and health of preserved SGNs. In this study, we assessed whether autophagy induction via rapamycin, a crucial cellular process responsible for maintaining cellular homeostasis and health, can be combined with a pulsed electromagnetic field (EMF) stimulation to strengthen the growth and health of neonatal SGNs, cultured in-vitro. The results showed that EMF stimulation plays a role in autophagy and that combining rapamycin and EMF stimulation strengthens the SGN outgrowth significantly. This effect and the impact on morphological characteristics and cellular health varied sensitively with different concentrations of rapamycin. This study demonstrates that modulation of autophagic activity, in combination with other methods, may be utilized as a potential therapeutic strategy to enhance the efficacy of cochlear implants.
Abstract (croatian)
Neuroni spiralnog ganglija (NSG) su primarni auditorni neuroni odgovorni za prijenos auditornog signala iz osjetnih stanica s dlačicama do kohlearne jezgre u mozgu. Njihova degeneracija, uz oštećenje osjetnih stanica s dlačicama, jedan je od glavnih uzroka zamjedbenog (senzoneuralnog) gubitka sluha (SNHL). Efikasnost najuspješnijeg uređaja medicinske bionike, kohlearnog implantata (umjetne pužnice), ovisi o broju i funkcionalnom stanju NSG. U ovome radu promotrili smo utjecaj primjene elektromagnetskog polja i indukcije autofagije preko primjene rapamicina, esencijalnog staničnog procesa odgovornog za održavanje homeostaze i zdravlja stanica, kao potencijalnu kombiniranu metodu promoviranja većeg rasta i zdravlja neonatalnih NSG-ova. Rezultati su pokazali da EMF stimulacija utječe na autofagiju, te da kombinacija rapamicina i EMF stimulacije može postići značajno veći rast NSG-ova. Ovaj efekt, kao i utjecaj na morfološke karakteristike i stanično zdravlje, varirao je srazličitim koncentracijama rapamicina. Ovaj rad pokazuje da se modulacija autofagijske aktivnosti u kombinaciji sa drugim metodama može koristiti kao potencijalna terapeutska strategija za pobolšanje efikasnosti umjetne pužnice.
