CD4 and rheumatoid arthritis: Support for this interpretation comes from Moharamoghli et al, 2019 who found that T cells from RA patients had higher amounts of GAS5 than those from controls (Moharamoghli et al., 2019), Also, Suo et al, 2018 documented that GAS5 and miR21 levels were considerably higher in CD4+ T cells from SLE patients than in control subjects, and GAS5 expression in CD4+ T cells was higher in ulcerated SLE patients than in non-ulcerated SLE patients (Suo et al., 2018).
