To do this, the researchers picked out CD8 T cells from the tumours of 36 lung cancer patients and 41 with head and neck cancer, and looked at the cells' genetic make-up.
Lalvani asserted that their findings suggest that by making the body produce more of this specific type of CD8 T cell, you can protect people against symptomatic illness and this could provide the blueprint for developing a universal flu vaccine.
Lalvani said: "The immune system produces these CD8 T cells in response to usual seasonal flu.
Antigen-independent memory CD8 T cells do not develop during chronic viral infection.
Activation of memory CD8 T cells upregulates CD38 expression, which makes it a good marker of cellular activation in this subset.
