Molecular and functional analysis of mouse decay accelerating factor (CD55).
Molecular cloning of mouse decay accelerating factor (DAF; CD55) predicted two forms of the molecule, one transmembrane (TM) and the other glycosylphosphatidylinositol (GPI)-anchored; these are encoded by separate genes termed Daf-GPI and Daf-TM. In the present study several additional isoforms of mouse DAF, generated by alternative splicing from these genes, are described. Northern-blot analys...
متن کاملDecay accelerating factor (CD55): a target for cancer vaccines?
The 791Tgp72 antigen has been used successfully as a target for tumor imaging and T-cell immunotherapy. We have characterized this antigen using the monoclonal antibody 791T/36 as a 72/66 kDa doublet. NH2-terminal protein sequencing of the two bands revealed identity with the complement regulatory protein CD55. Antibodies recognizing different domains of CD55 were also shown to bind to the puri...
متن کاملCoxsackieviruses B1, B3, and B5 use decay accelerating factor as a receptor for cell attachment.
Receptor binding and subsequent cell-mediated internalization or disassembly are the initial steps in virus replication. Cell surface molecules that participate in this process are the primary determinants of virus tissue tropism. Monoclonal antibody blockade, immunoprecipitation, and DNA transfection were used to identify decay accelerating factor as a major cell attachment receptor for coxsac...
متن کاملThe HeLa cell receptor for enterovirus 70 is decay-accelerating factor (CD55).
Enterovirus 70 (EV70) is a recently emerged human pathogen belonging to the family Picornaviridae. The ability of EV70 to infect a wide variety of nonprimate cell lines in vitro is unique among human enteroviruses. The importance of virus receptors as determinants of viral host range and tropism led us to study the host cell receptor for this unusual picornavirus. We produced a monoclonal antib...
متن کاملThe Expression and Action of Decay-Accelerating Factor (CD55) in Human Malignancies and Cancer Therapy
Decay-accelerating factor (DAF, CD55) is physiologically acting as an inhibitor of the complement system, but is also broadly expressed in malignant tumours. Here DAF seems to exert different functions beyond its immunological role such as e.g. promotion of tumorigenesis, decrease of complement mediated tumor cell lysis, autocrine loops for cell rescue and evasion of apoptosis, neoangiogenesis,...
