The aim of this study was to evaluate CD25+ and Lag3+ T regulatory subpopulations in patients with critical carotid artery stenosis (CAS) and Stanford-A acute aortic dissection (AAD). CD25+ and Lag3+ were measured in 36 patients affected by CAS and 24 patients with Stanford type A AAD. Based on neurological symptoms, patients affected by CAS were further divided in 25 asymptomatic (CAS-A) and 11 symptomatic (CAS-S) subjects. Twenty-five patients with traditional cardiovascular risk factors (RF), matched for age and sex, were used as control group. Interleukin (IL)-10, IL-6 and transforming growth factor-β-levels were also measured. CD25+ T cells were significantly increased in CAS-S versus CAS-A (p > 0.05), AAD (p > 0.05) and RF (p > 0.05). Moreover, a significant increase in Lag3+ Tregs was observed in CAS e CAS-S versus AAD (p < 0.05) and RF (p < 0.05), whereas no significant difference was observed between CAS-S and CAS-A. IL-6 was higher in AAD compared to the other groups. Patients with neurological symptoms display a peculiar expansion of CD25+ T cells, strongly confirming a relationship between ischemic brain damage and this regulatory subpopulation, whereas Lag3+ Tregs early distinguish CAS from AAD and probably exert protective actions against aortic wall rupture throughout their anti-inflammatory functions.

Abstract
The aim of this study was to evaluate CD25+ and Lag3+ T regulatory subpopulations in patients with critical carotid artery stenosis (CAS) and Stanford-A acute aortic dissection (AAD). CD25+ and Lag3+ were measured in 36 patients affected by CAS and 24 patients with Stanford type A AAD. Based on neurological symptoms, patients affected by CAS were further divided in 25 asymptomatic (CAS-A) and 11 symptomatic (CAS-S) subjects. Twenty-five patients with traditional cardiovascular risk factors (RF), matched for age and sex, were used as control group. Interleukin (IL)-10, IL-6 and transforming growth factor-β-levels were also measured. CD25+ T cells were significantly increased in CAS-S versus CAS-A (p > 0.05), AAD (p > 0.05) and RF (p > 0.05). Moreover, a significant increase in Lag3+ Tregs was observed in CAS e CAS-S versus AAD (p < 0.05) and RF (p < 0.05), whereas no significant difference was observed between CAS-S and CAS-A. IL-6 was higher in AAD compared to the other groups. Patients with neurological symptoms display a peculiar expansion of CD25+ T cells, strongly confirming a relationship between ischemic brain damage and this regulatory subpopulation, whereas Lag3+ Tregs early distinguish CAS from AAD and probably exert protective actions against aortic wall rupture throughout their anti-inflammatory functions.File | Dimensione | Formato | |
