Figure Lengend Snippet: Kaplan-Meier Survival Analysis in TETs The results demonstrated that PFS of TETs was closely related to CD55 mRNA ( A , p < 0.0001), CD55 protein ( B , p < 0.0001), tumor completeness of resection ( C , p < 0.0001), histological type ( D , p < 0.0001), Masaoka-Koga stage ( E , p < 0.0001), and adjuvant therapy ( F , p = 0.0009), but no with gender ( G , p = 0.1805) or MG ( H , p = 0.7269)

Figure Lengend Snippet: The relationship between CD55 and the clinical pathological features of patients The expression levels of CD55 mRNA and protein were higher in R1/R2 group ( A ), higher histological grade ( B ), Masaoka-Koga stage III/IV ( C ), adjuvant therapy ( D ) compared with the corresponding R0 group, normal thymus tissues, and stage I/II, and no-adjuvant therapy. Moreover, the expression of CD55 protein was significantly higher expressed in ≥ 60 years compared with ˂60 years ( E ). Additionally, CD55 protein expression was higher in males than that in females ( F ), whereas CD55 mRNA did not show similar results ( E, F ). Patients without MG showed higher CD55 mRNA and protein expression levels than those with MG, however, this difference was not statistically significant ( G ). There was also no statistically significant relationship between tumor diameter and CD55 expression ( H ). When CD55 protein was highly expressed, the mRNA level was also high ( I ).

Figure Lengend Snippet: C′ regulators are not significantly upregulated in H1975 and HEp2 PI cells. ( A , B ) RNA samples from H1975 ( A ) and HEp2 ( B ) cells were collected as described in the legend to . Samples were analyzed via RT-qPCR to determine gene expression of three C′ regulators: CD46, CD55, and CFH. Values were normalized to expression of β-actin. C′ inhibitor expression in mock-infected cell cultures was set equal to 1 and expression in AI and PI cel cultures is expressed as fold change relative to mock. ( C ) Mock-infected, AI, and PI HEp2 cells were stained with an anti-CD55 antibody and processed via flow cytometry.

Article Title: Complement-Mediated Two-Step NETosis: Serum-Induced Complement Activation and Calcium Influx Generate NADPH Oxidase-Dependent NETs in Serum-Free Conditions

doi: 10.3390/ijms25179625

Figure Lengend Snippet: Complement activation increases complement regulators on neutrophils. Neutrophils were precoated with anti-CD59 monoclonal antibodies and then exposed to normal human serum (NHS) to activate the complement cascade (complement stimulated). The group not treated with anti-CD59 monoclonal antibodies served as the unstimulated control (serum). The cells were then fixed, immunostained, and analyzed by flow cytometry. The expression level of all three complement regulators (CD46, CD55, and CD59) was significantly increased on complement-activated neutrophils compared to the unstimulated controls.
