We performed IHC in paraffin-embedded samples obtained from the CGGA sample bank. IHC analysis with AIF1 (Proteintech, 10904-1-AP, 1:500), TNF (Abcam, ab270264,1:150), CD163 (Abcam, ab189915, 1:500), and TIM3 (Abcam, ab241332, 1:500) antibodies were conducted according to our previous procedures [24 (link), 25 (link)]. The protein expression levels were evaluated independently by two experienced pathologists and the scoring criteria refer to our published article [25 (link)].
