The main neurological manifestation of COVID-19 is loss of smell or taste. The high
incidence of smell loss without significant rhinorrhea or nasal congestion suggests that …

The WNT signal transduction cascade is a main regulator of development throughout the
animal kingdom. Wnts are also key drivers of most types of tissue stem cells in adult …

BACKGROUND In adult mammalian organisms, multiple tissues—including the skin, blood,
stomach, and intestines—are entrapped in a state of permanent regeneration; older cells are …

The sense of taste is stimulated when nutrients or other chemical compounds activate
specialized receptor cells within the oral cavity. Taste helps us decide what to eat and …

The tongue is a complex multifunctional organ that interacts and senses both interoceptively
and exteroceptively. Although it is easily visible to almost all of us, it is relatively …

Leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5) and its homologs (eg,
Lgr6) mark adult stem cells in multiple tissues. Recently, we and others have shown that …

The sense of taste, or gustation, is mediated by taste buds, which are housed in specialized
taste papillae found in a stereotyped pattern on the surface of the tongue. Each bud …

The year 2020 became the year of the outbreak of coronavirus, SARS-CoV-2, which
escalated into a worldwide pandemic and continued into 2021. One of the unique symptoms …

Adult stem cells self-renew and replenish differentiated cells in various organs and tissues
throughout a mammal's life. Over the last 25 years an ever-growing body of knowledge has …

Despite evidence that the ability to taste is weakened by obesity and can be rescued with
weight loss intervention, few studies have investigated the molecular effects of obesity on …
