SSTR1 and thromboangiitis obliterans: In that report, the authors also showed that SSTR1, SSTR2, and SSTR4 mRNA expression was higher than SSTR3 and SSTR5 expression in lymphocytes from patients with TAO, but only SSTR2, SSTR3, and SSTR4 mRNAs were detectable at low level in lymphocytes from retroorbital tissues of control individuals.
