TRIM21 and synovial sarcoma: Among SS patients, ApoCell-phagocytosis by monocytes (ApoCell-PhI values) was found to correlate inversely with ESSDAI scores (r = −0.559, p = 0.004, Figure 1B) and to be significantly impaired among patients with type-I disease (in type-I disease; median: 168, range: 119–206, in type-II disease; median: 221, range: 130–338, p = 0.04) or with anti-Ro/SSA autoantibodies (in anti-Ro/SSA-positive; median: 164, range: 119–227, in anti-Ro/SSA-negative; median: 190, range: 142–338, p = 0.03).
