HIV – Is a cure possible?

Abstract

HIV is a chronic well manageable disease. Highly active antiretroviral therapy improves the quality of life of people living with HIV, but the treatment has to be continued lifelong, as the total cure has not been established. Cost of treatment, drug toxicities, interaction with other drugs and persistence of inflammation and acceleration of the aging process, all put together, warrant an urgent need for a total cure. Even though one case had been proved to be cured, still a practical cure is far beyond the reach. Numerous approaches and strategies had been put forth to achieve a cure; still they are to be proved with human studies. This article reviews the major approaches, recent advances in the venture of HIV cure, and the safety concerns involved.

HIV/AIDS: Current Updates on the Disease, Treatment and Prevention

“…A breakthrough technique, the CRISPR/Cas9 gene-editing system, is also used to eliminate the CCR5 receptor on the blood stem cells which can give rise to differentiated blood cells that are devoid of this receptor [ 18 ] (Fig. 8 ).…”

“…8 ). These gene-edited stem cells can be established into an HIV-infected patient through bone marrow transplantation and give rise to an HIV-resistant immune system [ 18 ]. This technique, however, can also go sideways which leads to unwanted results that can cause ethical issues to rise.…”

“…Researchers have also engineered a molecule called the chimeric antigen receptor (CAR) and introduced a gene for that molecule into blood-forming stem cells [ 18 ]. This molecule has two receptors that will recognize the antigen (HIV) and direct the immune cells to locate and kill the HIV-infected cells [ 18 ].…”

“…Researchers have also engineered a molecule called the chimeric antigen receptor (CAR) and introduced a gene for that molecule into blood-forming stem cells [ 18 ]. This molecule has two receptors that will recognize the antigen (HIV) and direct the immune cells to locate and kill the HIV-infected cells [ 18 ]. When transplanted into mice, which would have the CAR-carrying blood stem cells, it would result in reduced levels of HIV by inducing the immune cells to fight effectively against the virus [ 18 ].…”

Identification and differential expression of serotransferrin and apolipoprotein A-I in the plasma of HIV-1 patients treated with first-line antiretroviral therapy

“…HIV drug resistance is a major problem and a threat in epidemic control [ 3 ]. There is no specific option to cure AIDS [ 4 ]. Clinically significant interactions between the drug and plasma proteins were observed.…”
