Article Title: The effect of anti-HLA class I antibodies on the immunological properties of human glomerular endothelial cells and their modification by mTOR inhibition or GCN2 kinase activation

doi: 10.3892/mmr.2021.11994

Figure Lengend Snippet: Effect of anti-HLAI on ICAM-1, HLA-DR, CD46 and CD59, and the impact of halofuginone or everolimus treatment. (A) Representative experiment for each of the evaluated factors. (B) Cumulative results are presented. Anti-HLAI antibodies upregulated ICAM-1, HLA-DR, CD46 and CD59. Halofuginone or everolimus treatment decreased ICAM-1. Data are presented as the mean ± SEM. *P<0.05 vs. control cells, # P<0.05 vs. anti-HLAI-treated cells, ^ P<0.05 vs. anti-HLAI-treated cells administered halofuginone, + P<0.05 vs. anti-HLAI-treated cells administered everolimus and $ P<0.05 vs. anti-HLAI-treated cells with halofuginone and everolimus. HLAI, human leukocyte antigen class I; ICAM-1, intracellular adhesion molecule-1; Hal, halofuginone; Ever, everolimus; Ctrl, control.

doi: 10.1128/IAI.69.9.5840-5848.2001

Figure Lengend Snippet: Immunocytochemical analysis of adhesion molecule expression by cervicovaginal epithelial cells in vitro and in vivo. Positive cells appear red. (A and B) Constitutive expression of CD46 in endocervical tissue (A) and endocervical cell culture (B). (C to G) Expression of CD66 in vaginal tissue (C), ectocervical tissue (D), endocervical tissue (E), uninfected endocervical cell culture (F), and endocervical cell culture after 8 h of infection with the N. gonorrhoeae F62 piliated variant (G). (H to K) Expression of ICAM-1 in endocervical cell cultures with no infection (H), following 8 h of TNF-α stimulation (I), following 8 h of infection with N. gonorrhoeae piliated F62 (J), or following 8 h of infection with N. gonorrhoeae nonpiliated F62 (K).

Article Snippet: Anti-human CD46 antibody (mouse monoclonal MAS657) was purchased from Accurate Chemical and Scientific Corporation, Westbury, N.Y. Fluorescein isothiocyanate (FITC)-conjugated pan-CD66 antibody (mouse monoclonal F7112) recognizing an epitope common to four members of the CD66 family (CD66a, -b, -c, and -e) was purchased from Dako, Carpinteria, Calif.
