Research demonstrates that killer T cells can support tissue regeneration

The research at the Leibniz Institute has shown that human killer T cells, as well as destroying damaged or infected cells, can support tissue regeneration via the secretion of growth factors and immune messengers. This effect can also promote tumor growth. The results indicate a potential to promote wound closure and tissue functionality restoration, but also a risk of enhancing undestroyed tumor cells. Future research aims to find a way to harness the destructive capabilities of CD8 T cells while inhibiting their ability to support tumor growth. The study is titled “The effector program of human CD8 T cells supports tissue remodeling” and is published in the Journal of Experimental Medicine.
