Summary
Recent advances in ART include new integrase inhibitors and fixed-dose combinations, expanding treatment options. Further research is exploring nucleoside-sparing regimens and generic antiretrovirals.
Area of Science:
- Infectious Diseases
- Pharmacology
Background:
- The landscape of antiretroviral therapy (ART) is continually evolving.
- New drug classes and formulations aim to improve efficacy, safety, and patient adherence.
Purpose of the Study:
- To review recent advancements in antiretroviral therapies.
- Highlighting new drug approvals and ongoing clinical trials.
Main Methods:
- Review of recent clinical trial data.
- Analysis of newly approved fixed-dose combinations and drug formulations.
Main Results:
- Demonstrated safety and efficacy of integrase inhibitors (raltegravir, elvitegravir, dolutegravir) and rilpivirine.
- Approval of two new single-pill fixed-dose combinations (FDCs).
- Cobicistat identified as a potential booster for elvitegravir and atazanavir.
Conclusions:
- The antiretroviral armamentarium has expanded significantly with new integrase inhibitors and FDCs.
- Future research focuses on less toxic formulations and nucleoside-sparing regimens.

Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
