Heparin 23-30 thrombospondin 1 Homo sapiens 132-135 1712815-8 1991 Therefore, two distinct TSP receptors appeared to exist on unactivated PMN; one interacting with the heparin-binding domain of TSP and one interacting with a different site. Heparin 101-108 thrombospondin 1 Homo sapiens 24-27 1712815-8 1991 Therefore, two distinct TSP receptors appeared to exist on unactivated PMN; one interacting with the heparin-binding domain of TSP and one interacting with a different site. Heparin 101-108 thrombospondin 1 Homo sapiens 127-130 1712815-15 1991 The existence of a subset of TSP receptors that were heparin-inhibitable on PMN suggests that binding of TSP may trigger functionally independent responses. Heparin 53-60 thrombospondin 1 Homo sapiens 29-32 1712815-15 1991 The existence of a subset of TSP receptors that were heparin-inhibitable on PMN suggests that binding of TSP may trigger functionally independent responses.
