Abstract Complement receptor type 2 (CR2, CD21) is expressed by both human and murine
B cells and has been demonstrated to play a pivotal role in the humoral immune response …

In mice CR1 and CR2 are encoded at a single locus and the two alternatively spliced RNA
transcripts of the CD21 gene generate murine CR1 and CR2 (CR1/2). While the function of …

We found that transgenic (tg) mice stably expressing a bacterial artificial chromosome (BAC)-
derived human complement receptor type 2 (CR2/CD21) gene demonstrate B cell specific …

T lymphocytes from 42 healthy blood donors were examined for expression of CR1 on the
cell surface using a fluorescence-activated cell sorter. The fraction of CR1-positive T …

Abstract Complement receptor (CR) type 2 (CR2/CD21) is normally expressed only during
the immature and mature stages of B cell development. In association with CD19, CR2 plays …

Complement receptor 1 (CR1, CD35) and complement receptor 2 (CR2, CD21) have been
implicated as regulators of B-cell activation. We explored the role of these receptors in the …

Covalent attachment of activated products of the third component of complement to antigen
enhances its immunogenicity, but the mechanism is not clear. This effect is mediated by …

Abstract Complement receptor type 2 (CR2)/CD21 is a B lymphocyte cell membrane
C3d/iC3b receptor that plays a central role in the immune response. Human CR2 is also the …

Abstract The complement receptor 3 (CR3; CD11b/CD18) is present exclusively on
leukocytes, particularly on NK cells, monocytes and polymorphonuclear neutrophils …

SUMMARY Complement receptor 2 (CR2, CD21), the receptor for both the C3d, g portion of
human complement component C3 and the Epstein‐Barr virus, has been recently described …
