Article Title: Proteome microarray-guided identification of mycobacterial antigens and ELISA-based peptide mapping for improved serological detection of Mycobacterium bovis infection in European badgers

doi: 10.1128/jcm.01260-25

Figure Lengend Snippet: Mean microarray antigen spot intensities from TB-free badger serum samples at two time points following experimental infection. White bars represent TB-free sera; gray bars represent TB-infected sera collected at ( a ) 8 weeks and ( b ) 12–13 weeks post-infection. Mean microarray spot intensities (log 2 -normalized) are shown with 95% confidence interval error bars. Paired-sample t -tests were carried out comparing pre- and post-infection mean spot intensities. Antigens were ranked by BH-adjusted P -values, and the 10 most differential antigens (defined as those with the lowest BH-adjusted P -values) for each comparison group are shown. Significance levels: ns: P ≥ 0.05; *: P < 0.05; **: P < 0.01; and ***: P < 0.001.

doi: 10.1128/jcm.01260-25

Figure Lengend Snippet: Mean microarray antigen spot intensities from TB-infected and BCG-vaccinated badger serum samples. Gray bars represent sera from TB-infected badgers collected 12–13 weeks after experimental infection; white bars represent sera from badgers that received ( a ) a single BCG vaccination or ( b ) two BCG vaccinations. Mean spot intensities (log₂-normalized) are shown with 95% confidence interval error bars. Independent-samples t -tests were used to compare antigen intensities between TB-infected and BCG-vaccinated groups. Antigens were ranked by BH-adjusted P -values, and the 10 most differential antigens (defined as those with the lowest BH-adjusted P -values) for each comparison group are shown; ***: P < 0.001.

Article Title: Mapping autoantibody targets of full-length C-reactive protein in systemic lupus erythematosus: importance for neutrophil function and classical complement activation

doi: 10.3389/fimmu.2025.1578372

Figure Lengend Snippet: Dot-plot between anti-CRP antibodies and epitope positivity. The graph displays anti-CRP antibodies versus the number of positive epitopes obtained with microarray-based linear epitope mapping in patients with systemic lupus erythematosus ( n =42). (CRP, C-reactive protein).

Figure Lengend Snippet: Heatmap representation of autoreactivity against CRP obtained with microarray-based linear epitope mapping of the full CRP monomer. (A, B) Individual signal intensity of IgG autoantibody reactivity against full-length CRP for subjects with SLE ( n =42) and HBD ( n =11). (C–E) Mean signal intensity of IgG autoantibody reactivity against motifs of full-length CRP comparing anti-CRP negative (anti-CRP–; n =16) vs. anti-CRP positive (anti-CRP+; n =26) patients with SLE, patients with ( n =6) and without ( n =36) active disease, and no damage ( n =20) vs. irreversible organ damage (any organ system; n =22). Each column represents one subject (A, B) or the mean value of a group (C–E) . Each row represents a 15 amino acid long sequence covering the full length of the protein with 14 amino acids overlap and 7 amino acid GS repeats elongated before and after the protein sequence.
