Major histocompatibility complex class I-related chain A (MICA) molecules are frequently
expressed in lymphoproliferative malignancies including multiple myeloma (MM). MICA
activates NK cells and co-stimulates T cells by interaction with its immunoreceptor NKG2D.
In contrast, soluble MICA (sMICA) molecules impair the functions of NKG2D+ T and NK cells,
which may facilitate tumor cell escape from immunosurveillance. Here, we analyzed the
clinical relevance of sMICA in 97 MM patients. sMICA (mean±SEM pg/ml) was significantly …
