HSVEC infected with 5000 vp/cell for 3 hours at 37°C. β-Gal activity was normalised to total protein levels (* = p <0.05 compared to Ad5, *** = p <0.001 compared to Ad5). β-Gal activity normalised to total protein in (C) HSVSMC and (D) HSVEC infected with 5000 vp/cell in the presence or absence of CD46 function-blocking antibody MEM258 or an isotype matched control. (* = p <0.05 relative to isotype control, ** = p <0.01 relative to isotype control).

FITC conjugated Mouse anti Human CD46 antibody, clone MEM-258 (MCA2113F) used for the evaluation of CD46 expression levels on human cells and porcine cells transfected with human CD46 by flow cytometry.
Image caption:
Expression of Gal and CD46 on PBMC (A) and aortic endothelial cells (B) from WT, GTKO, CD46 (homozygous), and GTKO/CD46 (heterozygous) pigs and humans. Cells were stained with BSI‐B4 (a), or CD46 (b). Representative data of three experiments. Dotted lines – unstained or isotype control. Black lines – WT cells. Red lines – GTKO cells. Green lines – CD46 (homozygous) cells. Blue lines – GTKO/CD46 (heterozygous) cells. Purple lines – human cells. Although WT and CD46 pigs expressed Gal on PBMC and PAEC, GTKO and GTKO/CD46 pigs and humans did not express Gal on PBMC or on aortic endothelial cells (A[a] and B[a]). CD46 and GTKO/CD46 pigs expressed higher levels of CD46 on PBMC and PAEC than WT or GTKO pigs (A[b] and B[b]). CD46 (homozygous) pig PBMC and PAEC expressed higher levels of CD46 than GTKO/CD46 (heterozygous) pig cells and human cells.

F BA Reset| Mouse anti Human CD46 antibody, clone MEM-258 recognizes the human CD46 cell surface antigen, also known as membrane co-factor protein (MCP), Trophoblast leukocyte common antigen or TLX. CD46 is a 392 amino acid (including a 34 aa signal peptide) ~43-60 kDa single pass type 1 trans-membrane glycoprotein expressed by all cell types with the exception of erythrocytes. CD46 functions as a receptor for complement and inhibitor of complement activation, limiting the formation and activity of C3 convertases. CD46 is expressed by all nucleated cells, often as multiple isoforms (Seya et al. 1993) on the same cells. The molecule is also expressed by sperm and may be important in the process of fertilisation (Carver-Ward et al. 1996). CD46 is reported to function as a receptor for adenovirus in a range of human cells and cell lines (Wu et al. 2024). |
