Experimental details: Immunofluorescent analysis of CD31 (green) showing staining in the cytoplasm and membrane of THP-1 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a CD31 monoclonal antibody (Product # MA5-13188) in 3% BSA-PBS at a dilution of 1:20 and incubated overnight at 4 ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

Experimental details: Immunofluorescence analysis of Platelet endothelial cell adhesion molecule was performed using 70% confluent log phase HUVEC cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with CD31 Monoclonal Antibody (JC/70A) (Product # MA5-13188) at 1:100 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32766), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b: Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300 dilution). Panel d represents the merged image showing Cell Junctional localization. Panel e represents no expression in MDA-MB-231. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Experimental details: Figure 6 EMPs are taken up by normal cells. ( A ) Cells were incubated with an equal concentration of CFSE-EMPs (green), then fixed (but not permeabilized) and stained with anti-CD31 to outline the plasma, and visualized using confocal microscopy after 1/2h,15h. (Bars=5mum) ( B ) Differential uptake of HG-EMPs and control-EMPs by normal HUVECs. All data were expressed as means +- SEM (Four fields of view are randomly selected for each group.

A The timeline to establish OVA-induced chronic asthma models and therapeutic interventions (see the ""Materials and methods"" section for details). The mice were divided into three groups: the control group (Control), OVA-induced chronic asthma group (OVA), and rapamycin-treated group (Rapa). B The total number of leukocytes and eosinophil count in the BALF were counted using Wright-Giemsa staining. C Representative photographs of H&E staining (upper panels) and Masson's staining (lower panels) of lung tissues (scale bar: 100 mum). D Inflammation score (left panels) and Wat/Pbm (right panels) of lung tissues. E Immunoblotting of the indicated proteins in lung tissues. F IHC analysis of the indicated proteins in lung tissues (scale bar: 100 mum). n = 8 mice per group. Results are shown as mean +- SD. ** P < 0.01; *** P < 0.001; **** P < 0.0001.
