In contrast to normal cells, HIV reservoir cells harbor a latent reservoir of HIV proviruses with the potential for replication. Three major genome editing technologies have been used to eliminate the HIV provirus, including Zinc-finger nuclease (ZFN) technology, the effects of transcription activator-like effector (TALENS), and clustered normal interspaced short palindromic repeat (CRISPR) and CRISPR-associated protein 9 (CRISPR-Cas9) technologies. This article will review the advancements in developing strategies for both sterilizing and functional HIV cures. From this perspective, the functional cure is as important as the sterilizing cure. Moreover, the human genome has integrated a large number of retrotransposon sequences over the course of evolution, and HIV may coexist with humans if it is restricted. Studies on вЂњHIV controllersвЂќ are expected to provide important clues for the development of therapies or strategies for functional HIV cure, such as therapeutic vaccines and vector-mediated gene transfer therapy. вЂњHIV controllersвЂќ are considered to be those patients whose HIV RNA is kept below the clinical baseline for a long period without cART. ДЇunctional cure refers to the long-term control of HIV replication, which involves maintaining a normal CD4 + T cell count and HIV replication below a detectable level. However, other strategies to carry out an effective sterilizing HIV cure are under development, such as genome editing, gene therapy, and shock and kill. Thus, this treatment model is difficult to reproduce. However, it is very difficult to find donors with human leukocyte antigens (HLA) identical to those of recipients for CCR5 Delta32/Delta32 stem cell transplantation, while the mortality rate of transplant surgery is up to 30%.

Eight years later, he appears to be free of both HIV and AML. The CCR5delta32 mutation stem cell is a kind of CCR5-deficient cell, which renders cells highly resistant to HIV-1 infection. Timothy Brown, the so-called Berlin patient, positive for both HIV and acute myeloid leukemia (AML), received two stem cell transplants from a donor homozygous for the CCR5delta32 mutation. The famous вЂњBerlin patientвЂќ represents one successful case of a sterilizing cure. Two types of HIV cures are under development: the вЂњsterilizing cureвЂќ and the вЂњfunctional cure.вЂќ A sterilizing cure refers to the complete elimination of replication-competent proviruses. Although cART is directed against cells that replicate HIV, it has no effect on cells carrying latent HIV reservoirs, demonstrating the ineffectiveness of cART as an HIV cure. During transcription of the provirus DNA is inhibited, thereby allowing the provirus to evade clearance by the host immune system. The key obstacle to an HIV cure is latent HIV reservoirs, which are mainly composed of resting memory CD4 + T cells in the early stages of HIV infection. Therefore, new theory and methods are urgently needed for the development of an effective HIV cure. In addition, long-term medication may increase the risk of adverse reactions, such as immune system disorders, nervous system disorders, and increase of viral reservoirs. However, individuals on cART require lifelong adherence, and withdrawal of the therapeutic regimens inevitably leads to rebound of HIV replication. It has prolonged lifespan, improved quality of life, and transformed HIV infection from a fatal disease into a chronic infectious disease. IntroductionД¬ombined antiretroviral therapy (cART) has enabled the sustained control of viremia in virtually all human immunodeficiency virus (HIV) patients.

This review focuses on recent advancements and future prospects for HIV cures. Based on these concepts, significant progress has been made in different areas. Currently, two types of HIV cures are in development: a вЂњsterilizing cureвЂќ and a вЂњfunctional cure.вЂќ A sterilizing cure refers to the complete elimination of replication-competent proviruses in the body, while a functional cure refers to the long-term control of HIV replication without treatment. However, the eradication of latent HIV reservoirs remains a challenge for curing HIV infection (HIV cure) because of HIV latency in primary memory CD4 + T cells. Combined antiretroviral therapy (cART) has been successful in prolonging lifespan and reducing mortality of patients infected with human immunodeficiency virus (HIV).
