LILRB1 and systemic lupus erythematosus: Our group has previously reported that T lymphocytes from SLE patients show an abnormal expression and a defective function of the inhibitory receptor ILT2 [23]; even more, we showed that SLE patients have a lower expression of ILT2 on peripheral mDC and pDC compared to healthy controls; however, when we assessed ILT2 function on moDC from SLE patients, we observed that this receptor does not have a critical role in regulating DC maturation [22].
