Summary
Current HIV-1 therapies manage disease but don't eliminate the virus. Investigating RNA interference therapeutics offers a promising strategy for a functional HIV-1 cure through cell transplant therapy.
Area of Science:
- Molecular Biology
- Virology
- Immunology
Background:
- Antiretroviral therapies for Human Immunodeficiency Virus type 1 (HIV-1) manage disease progression but do not eradicate the virus.
- Achieving a functional cure for HIV-1, defined as controlling viral replication without drug therapy, remains a significant clinical challenge.
- Cellular transplant therapies expressing anti-HIV-1 agents are being explored as a potential route to viral elimination.
Purpose of the Study:
- To review RNA interference (RNAi) pathways in mammalian cells for therapeutic applications.
- To discuss the design principles of small RNAs targeting pathogenic RNA sequences, specifically for HIV-1.
- To examine studies identifying RNAi-based therapeutics for HIV-1 and their potential in combination gene therapy.
Main Methods:
- Review of existing literature on RNA interference pathways in mammalian systems.
- Analysis of studies focused on developing small RNA therapeutics against HIV-1.
- Evaluation of the role of RNA interference in potential HIV-1 cure strategies.
Main Results:
- Small RNAs utilizing RNA interference pathways are effective in targeting HIV-1 replication.
- These small RNAs have been incorporated into gene therapy combinations for clinical trials.
- Research has identified several anti-HIV-1 RNA interference therapeutics.
Conclusions:
- RNA interference pathways provide a viable mechanism for developing novel HIV-1 therapeutics.
- Small RNA-based gene therapy holds promise for achieving a functional cure for HIV-1 infection.
- Combination gene therapy strategies incorporating RNA interference are advancing towards clinical application for HIV-1.

28.2K
RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

01:20Curing of Concrete
378
The hydration of cement takes place within the water-filled capillary pores. However, environmental elements can disrupt this process by evaporating water from the concrete surfaces. Sealed concrete with a water-cement ratio below 0.5 experiences self-desiccation, leading to water loss. The water loss in concrete is mitigated by curing. This technique involves keeping the concrete saturated to maintain the necessary temperature and moisture conditions, to optimally fill the spaces in the cement...

01:26Curing Methods
315
Concrete members with a small surface-to-volume ratio are cured by oiling and moistening the forms before casting the concrete member. These forms can be left in place for a prolonged period to prevent moisture loss, and can be wetted if made of a material suitable for wetting. If the forms are removed early, the concrete member is moistened and covered with polythene sheets to maintain moisture. For large horizontal concrete surfaces exposed to dry weather, a temporary covering is suspended...

02:18Interference and Diffraction
52.6K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

01:25Accelerated Curing of Concrete
491
Accelerating concrete curing is achieved by applying heat and additional moisture. This process accelerates the hydration of the cement, resulting in an earlier strength gain in the concrete. Steam curing is a method wherein the concrete products are either transported through a chamber on a conveyor belt or encased in plastic, allowing steam at atmospheric pressure to circulate freely around them. This process begins with a phase of moist curing that typically lasts between 3 to 5 hours, after...

11.1K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...
