摘要:
The invention relates to cell lines from differentiated cells with hepatocytic phenotypes capable of producing albumin and blood coagulation factors, said cells being derived from a human leukaemia cell line, preferably the human THP1 cell line, and preserving the characteristics of immortality. Among the cell lines of the invention, the cell lines known as PSC-THP1-EP, PSC-THP1-EP-FAST, PSC-THP1-HEP and PSC-THP1-EPEP are preferred. The invention also relates to methods for obtaining the cell lines of the invention and the uses of said cell lines, particularly for the production of albumin and/or blood coagulation factors.

The present invention relates to immortal pluripotent stem cells derived from a human leukaemia cell line, preferably a human monocytoid cell line and more preferably the human monocytoid cell line, THP1. The present invention further relates to cell lines derived from the immortal pluripotent stem cell line having the phenotype of cell strains characteristic of human tissues, particularly having a human hepatocyte phenotype, as well as the methods for preparing thereof. The present invention further relates to the use of the derived cell line with a human hepatocytic phenotype for the production of albumin and blood coagulation factors.
摘要:
The present invention relates to a drug combination capable of conferring therapeutic benefits in the treatment of both AIDS and malaria. In particular, it relates to a drug combination including at least one quinolinic antimalarial compound such as chloroquine or hydroxychloroquine, and at least one inhibitor of the Human Immunodeficiency Virus (HIV) protease enzyme. This drug combination is capable of inhibiting the replication of both HIV and Plasmodium sp. It also relates to the direct antimalarial effects of the HIV PIs.
摘要:
A novel approach to the development of a personalized vaccine. This approach is based on: A) sequencing of the gag gene from an HIV-infected individual treated with antiretroviral therapy; B) sequencing of the HLA alleles of the same individual; C) selecting the epitopes recognized by the individual's own HLA Class I within the highly-conserved Gag256-377, Gag147-169 and/or Gag225-251 amino acid sequences. An original algorithm that designs the target peptide for the vaccine starting from viral and HLA sequences of an individual with HIV/AIDS, forms the core of the present invention. The original algorithm makes extensive use of existing open- source software for protein design. The peptides designed in this manner and accordingly synthesized may be exploited as a therapeutic vaccine against HIV/AIDS. Vehicles for such peptides may be an individual's own dendritic cells pulsed with the peptide combination or a specific viral or DNA vector leading to intracellular expression of the viral peptides. The present vaccine approach may contribute to control of viremia once antiretroviral therapies are suspended.
摘要:
Activation of HIV-1 replication causes oxidative stress, which in turn potentiates HIV-1 replication. The common basis for the compounds of the present invention is: A) the capacity of reactivating HIV-1 from latency, and B) the ability to counteract the cellular machinery which activates in order to limit the effects of oxidative stress. In this way, oxidative stress can be potentiated and a “chain reaction” is sparked. This “chain reaction” induces a more efficient reactivation of HIV-1 from latency and, in some cases, induces selective killing of the infected cells. Actions A) and B) can either be carried out by one drug exerting both effects, or obtained by the combined use of distinct drugs. There are two main cellular machineries counteracting oxidative stress, i.e. the thioredoxin (Trx) thioredoxin reductase (TrxR) system and glutathione. Herein, we present drug strategies capable of exerting action B) by blocking either of the two machineries.
