Fig. 1From: Antimicrobial peptides in human synovial membrane as (low-grade) periprosthetic joint infection biomarkersImmunohistochemical LL-37 analysis in PJI synovial membrane. Representative stained paraffin sections with enhanced dyeing of LL-37 in patients with septic endoprosthetic loosening (SL) compared to aseptic endoprosthetic loosening (AL) and primary arthroplasty (PA). Semiquantitative analysis revealing significant (p < 0.05) LL-37 increase in SL vs. AL (up to ×9; **) and PA (up to ×20; *)Back to article page
