摘要:
The invention provides various reverse genetics systems for producing segmented RNA viruses, wherein the systems do not require bacteria for propagation of all of their expression constructs.
摘要:
Expression of a transgene is driven in a host cell using a pol I promoter which is not endogenous to an organism from the same taxonomic order from which the host cell is derived.

摘要:
This disclosure provides platforms for delivery of herpes virus proteins to cells, particularly proteins that form complexes in vivo. In some embodiments these proteins and the complexes they form elicit potent neutralizing antibodies. Thus, presentation of herpes virus proteins using the disclosed platforms permits the generation of broad and potent immune responses useful for vaccine development.
摘要:
This invention provides a modified gp140 envelope polypeptide of an HIV-1 isolate comprising a gp120 polypeptide portion comprising consecutive amino acids and a gp41 ectodomain polypeptide portion comprising consecutive amino acids, said gp41 ectodomain polypeptide portion being modified to comprise isoleucine (I) at an amino acid position equivalent to amino acid position 535; glutamine (Q) at an amino acid position equivalent to amino acid position 543; serine (S) at an amino acid position equivalent to amino acid position 553; lysine (K) at an amino acid position equivalent to amino acid position 567; and arginine (R) at an amino acid position equivalent to amino acid position 588, the amino acid positions being numbered by reference to the HIV-1 isolate KNH1144. This invention also provides nucleic acids encoding such a polypeptide, vectors, host cells, trimeric complexes and compositions thereof. Also provided are antibodies generated against the modified polypeptides and trimeric complexes, and methods of using the modified polypeptides, compositions and trimeric complexes.
