La Crosse virus soluble cell culture antigen.

Preparation of La Crosse virus hemagglutinating antigen in BHK-21 suspension cell cultures.

Hemagglutinating and complement-fixing antigens of La Crosse virus (California arbovirus group) were produced in serum-free suspension cultures of BHK-21/13S cells. The appearance and production of these antigens were correlated with the titer of infectious virus. No significant differences in antigen titers were produced by varying virus dose 10-fold. Hemagglutinin appeared 6 to 8 hr after ino...

Quantitative analysis of La Crosse virus transcription and replication in cell cultures and mosquitoes.

La Crosse (LAC) virus (family Bunyaviridae, genus Orthobunyavirus) small (S) segment negative-sense RNA genome (vRNA), positive-sense full-length RNA complement (vcRNA), and subgenomic mRNA were assayed in infected cell cultures and female Aedes (Ochlerotatus) triseriatus mosquito tissues using quantitative PCR (Q-PCR). During persistent infection of C6/36 (Aedes albopictus) and MAT (Aedes tris...

Human MxA protein protects mice lacking a functional alpha/beta interferon system against La crosse virus and other lethal viral infections.

The human MxA protein is part of the antiviral state induced by alpha/beta interferon (IFN-alpha/beta). MxA inhibits the multiplication of several RNA viruses in cell culture. However, its antiviral potential in vivo has not yet been fully explored. We have generated MxA-transgenic mice that lack a functional IFN system by crossing MxA-transgenic mice constitutively expressing MxA with genetica...
