doi: 10.1007/s12035-022-02762-1

Figure Lengend Snippet: AACT exosomal levels in dementia and AD cases monitored by distinct antibody-based approaches. AACT levels were assessed through immunoblot analysis or commercial ELISA assays in serum-derived exosomes from Controls (CDR = 0 and MMSE −) and individuals with dementia (CDR ≥ 1 and MMSE +) from UA-cohort ( a , d ), and AD clinically diagnosed cases from UA-cohort ( b , e ) or UMG-cohort ( c , f ). For WB, each point represents the relative densitometry ratio. For ELISA, each point represents the mean concentration value obtained for each individual. The solid horizontal line shows mean, and error bars indicates standard deviations. Abbreviations: AD, Alzheimer’s disease; C, Controls; CDR, Clinical Dementia Rate; MMSE, Mini-Mental State Examination. * p ≤ 0.05

Article Snippet: Further, AACT and C4BPα levels were also evaluated by enzyme-linked immunosorbent assay (ELISA), in serum-derived exosomes of the same individuals, using the commercial Human AACT ELISA Kit (ab217779; Abcam) or the Human C4 binding protein A ELISA Kit (NBP2-60,550; Novus Biologicals), according to manufacturer’s instructions.

Article Title: Toxoplasma gondii Recruits Factor H and C4b-Binding Protein to Mediate Resistance to Serum Killing and Promote Parasite Persistence in vivo

doi: 10.3389/fimmu.2019.03105

Figure Lengend Snippet: Toxoplasma gondii recruits AP regulator Factor H and CP/LP regulator C4b-binding protein to the parasite surface. 1 × 10 6 Type II ME49 parasites were incubated in 10% NHS for 0–60 min at 37°C. Western blots (left panels) of C4BP (A) (rabbit α-human C4BP, AssayPro 1:500) and FH (B) (goat α-human Factor H, CompTech 1:20,000) binding. Serum or purified protein was used as a positive control and heat inactivated serum (hiNHS) was used as a negative control. Blots were stripped and re-probed with anti-SRS29B (SAG1) for loading control. Images are from one representative of three independent experiments with similar results. Right panels (A,B) represent flow cytometric assays of C4BP (A) and FH (B) binding to the parasite surface for 0–60 min. Heat inactivated NHS (hiNHS) serum was used as a negative control. Flow cytometry data are shown as mean ± SEM from three independently performed experiments.

Article Snippet: The following antibody dilutions were used: rabbit anit-SRS29B (formerly SAG1, 30 kDa) 1:5,000, rabbit anti-C4BP (alpha chain, 70 kDa) (AssayPro) 1:1,000, goat anti-C3 (C3, C3b, iC3b) and goat anti-Factor H (full length protein, 155 kDa) antibodies (CompTech) were both used at 1:20,0000, anti-rabbit HRP 1:10,000 (Sigma), and anti-goat HRP 1:5,000 (Santa Cruz Biotechnology, Inc.).

Figure Lengend Snippet: Factor H and C4b-binding protein contribute to serum resistance. Factor H (FH) and C4b-binding protein (C4BP) were blocked by pre-incubating 10% NHS with 1:100 or 1:400 dilution of goat α-human FH (CompTech) or rabbit α-human C4BP (AssayPro) for 1 h on ice before adding to 1 × 10 6 parasites and incubating for 60 min at 37°C. Flow cytometric analysis of C5b-9 formation (A) and parasite viability (B) after 60' in 10% NHS blocked with 1:100 or 1:400 of α-C4BP (gray bars) α-FH (open bars) antibodies. 10% heat inactivated serum (hiNHS) was used a negative control. Flow cytometry data are shown as mean ± SEM from three independently performed experiments. Significant differences between the compared groups was determined using multiple Student's t test with Holm-Sidak correction for multiple comparisons, * p < 0.05, *** p < 0.001, **** p < 0.0001.
