Compared to HC, Foxp3(+) Helios(+) Treg in SLE predominantly displayed a CD45RA(-)/CD31(-)/FoxP3(low) memory phenotype with increased Ki-67 expression, enhanced basal pSTAT5a levels and a restricted TCR repertoire.
Relationship between endothelial dysfunction, videocapillaroscopy and circulating CD3+CD31+CXCR4+ lymphocytes in systemic lupus erythematosus without cardiovascular risk factors.
Sera from two patients with systemic lupus erythematosus (SLE) contained antibodies that immunoprecipitated surface molecules from platelets and fibroblasts that comigrated on SDS-PAGE and two-dimensional O'Farrell gels with platelet GPIa (VLA-alpha2 chain) and platelet GPIIa (VLA-beta chain).
We determined PECAM-1 polymorphisms, soluble PECAM-1, and CD40L levels in rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) and evaluated their associations with clinical atherosclerotic complications.
