Much of the coverage of COVID immunity often focuses on antibody response and for good reason - these small, y-shaped proteins can detect, and in some cases neutralise, viruses like SARS-CoV-2. But as variants like Omicron evolve to evade antibodies, the role of another part of the immune system, T cells, has been brought into sharper focus. These immune cells work in a different way to antibodies, attacking infected cells rather than the virus itself, which can make their response broader and more robust. Now, research is showing that, unlike antibodies, T cell potency is not impacted by the mutations in variants like Omicron. In this episode of&nbsp;Coronapod, we ask why T cells are so often overlooked, and what role they might be playing in our protection from the coronavirus.News:<a href="https://www.nature.com/articles/d41586-022-00063-0" rel="noopener noreferrer" target="_blank">‘Killer’ immune cells still recognize Omicron variant</a><a href="https://go.nature.com/get-the-nature-briefing?utm_source=coronapod&utm_medium=podcast&utm_campaign=shownotes" rel="noopener noreferrer" target="_blank">﻿Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.</a> &#10;&nbsp;<hr>See <a style='color: grey; ' target='_blank' rel='noopener noreferrer' href='https://acast.com/privacy'>acast.com/privacy</a> for privacy and opt-out information.
