The HIV-specific cytotoxic T lymphocyte (CTL) response is a critical component in controlling HIV replication and is an important part of the ultimate failure to eradicate the virus. Disclosed herein are methods for genetically enhancing the HIV-specific CTL response to allow long-term viral suppression or viral clearance. Human hematopoietic stem cells (HSCs) were genetically modified such that they differentiate into mature CTLs that will kill HIV infected cells. As disclosed herein, the functional effector cells are not human leukocyte antigen (HLA)-restricted. As disclosed herein, stem cells are transduced with non HLA-restricted chimeric antigen receptors (CARs) that allow the recognition of HIV or HIV infected cells when expressed by a CTL.

Methods for inducing a population of T cells to proliferate by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR) / CD3 complex or the CD2 surface protein. To induce proliferation of an activated population T cells, an accessory molecule on the surface of the T cells, such as CD28, is stimulated with a ligand which binds the accessory molecule. The T cell population expanded by the method of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis.

This invention provides formulations of the anti-HIV therapeutic, CD4-IgG2, that contain higher concentrations of the therapeutic than were previously prepared, are stable, compatible with lyophilization, and safe to administer. These formulations are suitable for intravenous, subcutaneous and intramuscular delivery, the latter two routes being potentially useful for facilitating self-administration by HIV-infected individuals. This invention is also directed to methods of making the CD4-IgG2 formulations described in the disclosure, and methods of using the formulations to inhibit or prevent infect CD4+ cells from becoming infected with HIV, and to treat subjects having CD4+ cells infected with HIV.

The invention provides a method for eliminating HIV in human blood and a device for treating AIDS with non-pharmacotherapy. The method includes (1) pumping the blood containing HIV virus into a soft thin plastic tube while adding air through a T-tube at a definite frequency so that the blood is evenly divided into very small blood droplets (2) introducing the small blood droplets into a screw-shaped quartz tube and exposing the quartz tube under a definite dosage of radiation to kill the HIV virus in the blood droplets is (3) collecting the treated blood in a storage bottle. Results show that after the HIV infected blood is divided into very small blood droplets and is irradiated with a definite dosage of ultraviolet (253.7 nm) for 90 seconds, more than 92% HIV loads in the blood is eliminated, while the lymphocyte (CD4+), erythrocyte, leucocyte and haemoglobin remain almost unchanged.

The invention relates to the technical field of immunotherapy of infectious diseases, in particular to recombinant gene construction of chimeric antigen receptor (CAR) for treating HIV (human immunodeficiency virus) infection and an application of the CAR. A single-chain antibody (ScFv) can identify gp120 of surfaces of HIV infected cells through series connection of antibody light chain and heavy chain variable zones of the gp120 of the surfaces of the HIV infected cells; the ScFv is prepared into the CAR, CAR coding genes are shifted to plasimid vectors, and lentiviral vectors shifted with the CAR coding genes are transduced to CD8+T lymphocytes. The CD8+T lymphocytes are discovered to be remarkable in restraining and killing activities of the HIV infected cells in both in-vitro and in-vivo experiments and can serve as active ingredients to prepare anti-HIV infection drugs, and good application prospect is achieved.

The invention discloses the application of RVX-208 as an HIV-1 latent infection reversing agent, belongs to the field of medicine, and relates to the application of RVX-208 (Apabetalone, RVX-000222) as an HIV-1 latent infection reversing agent. An important reason why HIV‑1 is difficult to be completely eliminated in the body is that HIV‑1 can lurk in the resting memory CD4 + in T cells. The RVX-208 of the present invention has good activity of activating HIV-1 latent cell pool in vitro, especially can efficiently activate the latent virus pool in HIV-infected patients, and can activate latent infection reversal agents such as protein kinase C with other mechanisms of action Drugs, histone deacetylase inhibitors and cytokines have a good synergistic effect. Compared with the known BET inhibitor JQ1, its in vitro cytotoxicity is greatly reduced, and the drug is safe and well tolerated. Therefore, RVX‑208 is expected to become a new and efficient HIV‑1 latent infection activator, so as to achieve the goal of completely eradicating the HIV‑1 latent infection pool and realizing the "functional" cure of HIV.

The present invention discloses a highly effective annonaceous acetogenins part medicine-idarubicin hydrochloride for injection, the preparation method and application thereof. The principal ingredient comprises alpha, beta-unsaturation gamma-double tetrahydrofuran loop type annonaceous acetogenins compound with lactone structure -bullatacin and shikemoxin. The ingredients of the type account for 90 percent or above of the total mass number. The preparation method of the present invention causes little environmental pollution, is simple and can be easily implemented. Large scale production can be realized. The highly effective annonaceous acetogenins part medicine-idarubicin hydrochloride for injection presented by the invention can be used for preparing medicines for curing malignant tumor, HIV infect / AIDS, resembling rheumatism, psoriasis and lupus erythematosus autoimmune disease. In the preliminary clinical test of treating malignancy, and HIV infect / AIDS, the idarubicin hydrochloride for injection shows the predominance beyond compare of the Chinese and Western medicine medication.

The invention relates to a compound composition of a traditional Chinese medicine, in particular to an anti-AIDS compound composition and a preparation method thereof. Pilos antler, wolfberry fruits, herba epimedii, rhizoma curculiginis, herba cistanches and other traditional Chinese raw materials are extracted, concentrated, decocted, filtered, concentrated, dried in vacuum, smashed and mixed to prepare the anti-AIDS compound composition. The compound composition is mainly used for treating AIDS patients and HIV-infected patients, and can restrain and kill AIDS virus improve the immunity of human bodies and increase the number of CD4 cells in human body, thereby eliminating all symptoms of patients and restoring the strength and weight of patients so that the patients can work and live healthily. The anti-AIDS compound composition is efficient and safe, causes no drug resistance and has no toxic side effects, no rebound after drug withdraw and wide application range.
