Similarly, studies by de Goeje et al. showed that LILRB4 is expressed on myeloid suppressor cells, and non–small cell lung cancer patients with a higher fraction of LILRB4high subsets in myeloid cells had a shorter median survival compared with the patients with a lower fraction of LILRB4high cells (de Goeje et al., 2015). Here, LILRB4 is linked to lung cancer.
