Are functionally active NKG2A-expressing natural killer cells elevated in rheumatoid arthritis patients compared to psoriatic arthritis patients and healthy donors?
This study demonstrates the presence of an elevated, functionally active NKG2A⁺ KIR- NK cell population in RA. Together with an elevated frequency of NKR-expressing T cells, these changes may reflect differential pathogenetic involvement.
