A recent study published in Scientific Reports explored the connection between COVID-19-related sensory deficiencies and changes in the tongue’s transcriptome. Researchers found that individuals with high levels of COVID-19 antibodies experienced impaired metallic taste and smell perception. The study identified specific genes associated with metallic taste perception, taste and smell receptors, and olfactory involvement in taste distortion. They also observed changes in gene expression related to sensory perception, with implications for chemosensory function. The study highlights the impact of COVID-19 on sensory perception and the need for further research on viral illnesses affecting taste and smell receptors.
