摘要:
The present invention relates to pharmaceutical preparations and methods for treating individuals infected with the human immunodeficiency virus (HIV). The pharmaceutical preparations comprise SAHA and another anti-viral agent. The invention also relates to methods for treating HIV infected patients, particularly patients with persistent, latent HIV infection of CD4+ T cells, and thus make it possible to not just suppress but to eradicate the HIV infection.
摘要:
The molecular mechanism of YY1/LSF-associated repression of HIV-1 is described herein. More particularly, an HIV transcription repressor complex containing YY1, LSF and HDAC1 is described. The invention is based on our discovery that (1) HDAC1 co-purifies with the LTR-binding YY1-LSF repressor complex; (2) the domain of YY1 that interacts with HDAC1 is required to repress the HIV-1 promoter; (3) the expression of HDAC1 augments repression of the LTR by YY1, and (4) the deacetylase inhibitor trichostatin-A blocks repression mediated by YY1. This novel link between HDAC1 recruitment and inhibition of HIV-1 expression by YY1 and LSF, in the natural context of a viral promoter integrated into chromosomal DNA, supports novel HIV therapies described herein and has significant implications for the long-term treatment of AIDS.
