Article Title: Phage Display-Derived Peptide for the Specific Binding of SARS-CoV-2

doi: 10.1021/acsomega.1c04873

Figure Lengend Snippet: Peptide 1 can specifically bind to the SARS-CoV-2 virus. (a) Schematic of the experimental procedure for the characterization of peptide binding with the heat-inactivated SARS-CoV-2 virus using the magnetic bead assay and TEM. (b–e) Biotinylated peptide 1 was immobilized on SA-coated magnetic beads to capture the virus. The gold nanoparticle-labeled SARS-CoV-2 antibody was used to detect the virus. The viruses and gold nanoparticles were visualized using TEM. The influenza virus served as a negative control. (b,c) Four individual magnetic beads with the addition of 0.67 and 0.067 mg/mL of the SARS-CoV-2 target to the surface, showing that gold nanoparticles (dashed red circle) have conjugated onto the magnetic beads. (d,e) Four individual magnetic beads with the addition of 0.67 and 0.067 mg/mL of influenza virus. The scale bar is 100 nm.

Article Snippet: The SARS envelope protein antibody used in the TEM assay was purchased from Novus Biologicals, LLC., Centennial, CO. N-Hydroxysuccinimide (NHS)-activated gold nanoparticles with a diameter of 40 nm were purchased from Cytodiagnostics Inc., Canada.

Article Title: Immunization-induced antigen archiving enhances local memory CD8+ T cell responses following an unrelated viral infection

doi: 10.1038/s41541-024-00856-6

Figure Lengend Snippet: a Experimental schematic for b – e . C57/BL6 mice were immunized subcutaneously in the footpad and/or flank with the indicated antigens and adjuvants. b Cells were stained with CD45, PDPN, CD31 and PD-L1. Cells were gated on CD45-PDPN + CD31- for FRC and CD45-PDPN + CD31+ for LECs. Shown are examples of LEC and FRC antigen-positive cells based on PD-L1 expression (floor, MARCO LEC) and ova-AF488+ from mice 2–3 weeks after immunization with ova conjugated to Alexa-Fluor 488 (AF488) and polyI:C and αCD40. c Quantification of the frequency of LEC, BEC, and FRC in the popliteal lymph node (pLN) that are positive for the indicated antigens administered with polyI:C and αCD40 at indicated time. d Same as ( b ) except for mice were immunized with SARS-CoV-2-RBD-AF488, polyI:C, and αCD40. e Same as in ( c ) except for SARS-CoV-2-RBD and CHIKV-E2 with polyI:C and αCD40. CHIKV-E2 was repeated for 9–14 days post-vaccine (~2 weeks). Statistical analysis was done using an unpaired t -test where the p -value between naïve and indicated antigen is <0.0001. In each experiment, at least n = 2–3 mice per group were evaluated and the experiment was repeated n = 2–5 times for c – e . Shown is the representative data from one of the experiments. Error bars are mean ± standard error of the mean. ns not significant, * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
