As shown in Fig 3, OFs from patients with TAO (#135, #137, #162) showed significantly higher levels of SSTR2 expression on their cell surface, compared to controls (#111, #116, #155) [mean fluorescence intensity (MFI) by flow cytometry: 269, 357 and 385 in TAO and 138, 87 and 129 in control]. Here, SSTR2 is linked to thromboangiitis obliterans.
