Figure Lengend Snippet: Male CIA mice exhibit higher disease severity compared to females. Male and female CIA and saline control mice were monitored for disease severity and assigned clinical scores from day 21 after the first CII challenge until the end of experiment (day 29). (A) Line graphs representing the mean clinical scores of mice starting from day 1 to day 29. On day 29 after the first CII challenge, mice were euthanized by cardiac puncture under anesthesia for blood and serum collection and storage at −80 °C. Serum concentrations of (B) anti-mouse collagen type II antibodies (left panel) and anti-bovine collagen type II antibodies (right panel) were analyzed by ELISA. N = 5 mice per group. One of two independent experiments. Simple linear regression analysis was performed to determine the statistical difference between the lines. One-way analysis of variance (ANOVA) followed by Tukey’s multiple comparison post hoc test was used to determine the statistical significance between the groups. (*/ # p ≤ 0.05, ** p ≤ 0.005 and ***/ ### p ≤ 0.0005). In Fig. 1A, # significance of comparisons between CIA and saline control mice; *significance of comparisons between sexes of CIA mice

Article Snippet: Serum levels of mouse anti-collagen antibodies (autoantibodies) and bovine anti-collagen antibodies (antibodies to the immunizing antigen) were determined by ELISA using a Mouse Anti-mouse Type II Collagen IgG Antibody Assay Kit and Mouse Anti-Bovine Type II Collagen IgG Antibody Assay Kit, respectively, according to the manufacture’s protocol (Chondrex Inc. WA, USA).

Article Title: Mesenchymal Stromal Cells Improve Salivary Function and Reduce Lymphocytic Infiltrates in Mice with Sjögren's-Like Disease

doi: 10.1371/journal.pone.0038615

Figure Lengend Snippet: Photomicrographs of CD45 − /TER119 − cells that undergone chondrocytic, osteogenic and adipocytic differentiation when cultured in differentiation media. Lower right photomicrograph represents CD45 − /TER119 − cells cultured in non-differentiating media (negative control). Collagen II (red) and DAPI (blue nuclei) are used to identify chondrocytes. Von kossa (black) and oil red stainings were used to identify osteoblasts and adipocytes, respectively. Graphs represent the number, size, and frequency of colony-forming unit fibroblasts (CFU-F) of CD45 − /TER119 − cells versus whole bone marrow cells. All three graphs show that CD45 − /TER119 − cells had higher CFU-F than whole bone marrow cells (* P <0.05).

Article Title: Berberine Delays Onset of Collagen-Induced Arthritis through T Cell Suppression

doi: 10.3390/ijms22073522

Figure Lengend Snippet: The effect of berberine on circulating anti-bovine type II collagen (CII) IgG in the CIA model. ( A ) Anti-CII IgG1, IgG2a, and total IgG at day 28 among all mice (arthritic and non-arthritic) within BBR, PBS (vehicle control), CIA (no treatment control), and non-CIA control animals ( n = 10 per group). ( B ) Anti-CII IgG levels at day 28 compared among arthritic mice only (BBR n = 5; PBS n = 9; CIA n = 9). Statistical comparisons made with the Kruskal–Wallis test with Dunn’s multiple comparisons. ( C ) Anti-CII IgG levels at day 28 compared among BBR-treated mice who developed arthritis (“arthritic”) vs. those that did not (“non-arthritic”). Statistical comparisons made with the Mann–Whitney U test. For all statistical tests in A–C, * p < 0.05, ** p < 0.01, **** p < 0.0001.

Article Snippet: Serum concentrations of anti-collagen type II (anti-CII) total IgG (catalog # 1012T), anti-CII IgG1 (catalog # 20321T), and anti-CII IgG2a (catalog # 20322T) were measured by ELISA (Chondrex, Redmond, WA, USA) according to the manufacturer’s instructions [ , ].
