A macrophage is a type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.

Scientists find key reason for ongoing loss of smell in long-COVID

In a recent study published in the journal Science Translational Medicine, researchers reported that long-term anosmia following coronavirus disease 2019 (COVID-19) could be a result of persistent T-cell mediated inflammation occurring in the olfactory epithelium even after the elimination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the olfactory tissue.
