Experimental details: Immunofluorescence analysis of Caveolin 1 was done on 70% confluent log phase A-375 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with Caveolin 1 Rabbit Polyclonal Antibody (Product # PA1-064) at 1 µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938).

Experimental details: Flow cytometry analysis of Caveolin 1 was done on U-87 MG cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with Caveolin 1 Rabbit Polyclonal Antibody (PA1064, red histogram) or with rabbit isotype control (pink histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Experimental details: FIGURE 1 HIV-1 infection alters cav-1, ocln, and Alix expression in brain pericytes. Pericytes were either mock-infected or infected with 60 ng/mL HIV-1 p24 for 48 h (A) or 72 h (B). The expression of cav-1, ocln, and Alix was evaluated by immunoblotting. GAPDH was used as a loading control. C, Representative immunostaining images of cav-1 (green), ocln (red), and Alix (purple) in mock-infected or HIV-1-infected for 48 or 72 h. Alix expression intensity was increased by the same factors in all groups to allow for better visualization. Graphs show the mean +- SD from three independent experiments. **** P < .0001, ** P = .003, * P < .0449, n = 4-9 per group; scale bars, 20 um

Experimental details: FIGURE 2 Cav-1, ocln, and Alix form a stable complex in mock-infected and HIV-1-infected pericytes. A, Diagram illustrating Alix and its binding partners identified in this study in a structural ribbon representation. The ESCRT-associated protein Alix binds tyrosine motifs via its C-terminal Proline Rich Domain (PRD). Caveolae are made up of oligomers of cav-1 and cavin proteins, and the figure shows a trimeric coiled coil for Cavin4a HR1 domain. For ocln, the region shown is the cytoplasmic C-terminal region that is known to bind scaffolding proteins. Figure was prepared using PyMol with the listed PDB accession numbers. B-E, Pericytes were either mock-infected (B) or infected with HIV-1 (C) for 48 h as in Figure 1 . A total of 600 ug of cell lysate protein was incubated with cav-1 antibody for 24 h, followed by incubation with protein A/G PLUS-Agarose beads. Both immunoprecipitates and supernatants were analyzed by immunoblotting for the presence of cav-1, ocln, and Alix. D, Immunostaining of cav-1 (green), ocln (red), and Alix (purple) in mock-infected or HIV-1-infected for 48 h. E, Cellular localization of the cav-1, ocln, and Alix complex in mock-infected or HIV-1-infected for 48 h. Cell membranes are visualized by blue fluorescent dye DiB (left panel). Middle panel, the cav-1, ocln, and Alix complexes merged with a bright field image of a single pericyte. The images were analyzed as in Figure 1 ; n = 4 per group; scale bar 5, 10, or 20 um

Experimental details: FIGURE 3 HIV-1 infection attenuates cav-1-mediated regulation of ocln expression. Pericytes were transfected with 1 ug cav-1 siRNA per 10 6 cells and either mock-infected or HIV-1-infected with 60 ng/mL HIV-1 p24 for 48 h. The expression of cav-1, ocln, and Alix was evaluated by immunoblotting (A), quantified, and compared among groups. GAPDH was used as a loading control. Cav-1 silencing (B) resulted in upregulation of occludin levels in mock-infected pericytes and this effect was attenuated in HIV-1-infected pericytes (C). Cav-1 silencing did not affect Alix levels (D). Graphs indicate the mean +- SD from three independent experiments. **** P < .0001, *** P = .0002, ** P = .003, n = 4-9 per group
