摘要:
The p21 gene encodes a cyclin dependent kinase inhibitor which affects cell cycle progression, but the role of this gene product in altering tumor growth has not been established. The present inventors have now discovered that the growth of malignant cells in vivo is inhibited by expression of p21. Expression of p21 resulted in an accumulation of cells in G0/G1, alteration in morphology, and cell differentiation.
摘要:
Monoclonal neutralizing antibodies are disclosed that specifically bind to the CD4 binding site of HIV-1 gp120. Monoclonal neutralizing antibodies also are disclosed that specifically bind to HIV-1 gp41. The identification of these antibodies, and the use of these antibodies are also disclosed. Methods are also provided for enhancing the binding and neutralizing activity of any antibody using epitope scaffold probes.
摘要:
Disclosed are antigens that include a target epitope that is defined by atomic coordinates of those amino acids of the antigen that contact an antibody of interest that specifically binds the antigen. The disclosed antigens have between about 10% and about 90% of surface exposed amino acid residues located exterior of the target epitope substituted as compared to a wild-type antigen and less than about 10% of the non-surface exposed amino acid residues substituted as compared to a wild-type antigen. Also disclosed are nucleic acids encoding these antigens and methods of producing these antigens. Methods for generating an immune response in a subject are also disclosed. In some embodiments, the method is a method for treating or preventing a human immunodeficiency type 1 (HIV-1) infection in a subject.

摘要:
The present invention provides compositions and methods for targeting gene transfer vectors to certain cell types by pseudotyping with a transmembrane form of viral glycoprotein, such as that from Ebola virus. The methods comprise the step of administering to a cell population a gene to be transferred operatively linked to an appropriate transfer vehicle, wherein the transfer vehicle is associated with a transmembrane form of viral glycoprotein.
