Enterovirus capsid interactions with decay-accelerating factor mediate lytic cell infection.
The cellular receptor usage of numerous human enteroviruses can differ significantly between low-cell-culture-passaged clinical isolates and highly laboratory-passaged prototype strains. The prototype strain of coxsackievirus A21 (CVA21) displays a dual-receptor specificity as determined with a receptor complex consisting of decay-accelerating factor (DAF) and intercellular adhesion molecule 1 ...
متن کاملBinding to decay-accelerating factor is not required for infection of human leukocyte cell lines by enterovirus 70.
Enterovirus 70 (EV70) is one of several human enteroviruses that exhibit a propensity for infecting the central nervous system (CNS). The mechanisms by which neurotropic enteroviruses gain access to and invade the CNS are poorly understood. One possibility is that circulating leukocytes become infected and carry neurotropic enteroviruses to the CNS. We examined the ability of EV70 to infect cel...
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 کاملDecay - Accelerating Factor - Release from Cell Membrane
Decay-accelerating factor (DAF) ~ is a membrane protein that inhibits amplification of the complement cascade on cell surfaces. By binding to C3b or C4b complement fragments that accidentally deposit on the cell membrane, DAF blocks the assembly of both the classical and alternative C3 and C5 convertases (1-3). In this manner, DAF protects host cells from damage by autologous complement. DAF is...
متن کاملA decay-accelerating factor-binding strain of coxsackievirus B3 requires the coxsackievirus-adenovirus receptor protein to mediate lytic infection of rhabdomyosarcoma cells.
The composition of the cellular receptor complex for coxsackievirus B3 (CVB3) has been an area of much contention for the last 30 years. Recently, two individual components of a putative CVB3 cellular receptor complex have been identified as (i) decay-accelerating factor (DAF) and (ii) the coxsackievirus-adenovirus receptor protein (CAR). The present study elucidates the individual roles of DAF...
