Scientists have come a step nearer find remedy for human immunodeficiency virus (HIV), with researchers of from Indian Institute of Science Schooling and Analysis (IISER), Bhopal figuring out a round RNA that performs an important function within the replication of HIV-1 virus.
HIV stays a significant international public well being problem that has claimed 40.4 million lives up to now globally.
For lengthy, the function of circRNA in HIV-1 replication remained unclear. The groundbreaking discovery by IISER Bhopal researchers of figuring out a selected round RNA circRNA known as ciTRAN that performs an important function within the replication of the AIDS-causing HIV-1 Virus throughout the Human physique, opens up new avenues for the event of novel therapeutic interventions for the illness.

Led by Dr. Ajit Chande from the Division of Organic Sciences at IISER Bhopal, this analysis sheds gentle on how ciTRAN facilitates the copying of genetic info from the virus, thereby enhancing the HIV replication effectivity.
What’s circRNA
Ribonucleic acid, or RNA, is a elementary molecule in residing cells liable for carrying genetic info and aiding in protein manufacturing. Whereas most RNAs have a linear construction with free ends, a singular kind referred to as round RNA (circRNA) types a closed-loop.
CircRNAs are identified to play an important function in regulating gene expression and are important for varied organic processes. Nevertheless, their involvement in HIV-1 replication has remained elusive for a substantial time.
Challenges in Characterising circRNA
Dr. Chande defined the complexities of characterising round RNA, emphasising that it’s typically much less plentiful, making its detection in its native type a difficult endeavor. He likened the method to following an advanced recipe. Moreover, when analyzing RNAs throughout viral infections, the huge quantity of viral info can overshadow much less widespread ones like circRNA. Due to this fact, progressive approaches have been wanted to determine and perceive the roles of those much less widespread RNA molecules.
A Novel Strategy: circDR-Seq
To beat these challenges, the researchers developed a pioneering method known as ‘circDR-Seq.’ This methodology enabled them to efficiently seize circRNAs from T-cells (white blood cells) contaminated with the HIV-1 virus. By this method, they pinpointed a selected circRNA referred to as ciTRAN, which performs a important function within the virus’s multiplication.
Uncovering Viral Hijacking
Dr. Chande, the lead researcher, elaborated on their findings, indicating that the HIV-1 virus makes use of host-encoded ciTRAN to multiply effectively. This revelation unveils a beforehand unknown aspect of how viruses, together with HIV-1, surmount transmission boundaries.
Promising Therapeutic Avenues
Other than this groundbreaking discovery, the researchers additionally developed a small protein molecule able to inhibiting viral transcription, particularly regarding virally-induced ciTRAN. By demonstrating how ciTRAN fuels the virus’s replication, this research opens up promising paths for the event of novel therapeutic interventions. Furthermore, the creation of a molecule with the potential to inhibit viral transcription represents a big leap in our efforts to fight HIV-1 and doubtlessly different viruses.
Director of IISER Bhopal, Prof. Gobardhan Das mentioned: “This work opens up new lines of investigations and may provide new leads for host-directed treatments.”
Conclusion
The identification of ciTRAN’s function in HIV-1 multiplication represents a significant breakthrough in HIV analysis. This newfound understanding of viral mechanisms and the event of a molecule able to inhibiting viral transcription deliver us one step nearer to efficient therapies for HIV-1 and doubtlessly different viral infections.
In keeping with a report by the World Well being Organisation (WHO) reviews that in 2022 alone, 630,000 individuals died from HIV-related causes and 1.3 million individuals acquired HIV. Presently, there isn’t any remedy for HIV an infection.
