1. Introduction

Noncoding RNA (ncRNA) regions, a diverse class of RNA molecules that do not code for proteins, have gained considerable recognition in recent years for their pivotal roles in cellular regulation. These regions, once overlooked and often referred to as "junk DNA," have proven to be far from redundant in the complex orchestra of molecular processes within the cell. The significance of noncoding RNA regions in cellular regulation is increasingly evident and is a fundamental focus of research across various biological contexts, including their role in HIV/AIDS pathogenesis, as highlighted in the title and abstract of this review [1].
Noncoding RNA molecules encompass a wide range of categories, including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). Each of these categories plays distinct roles in controlling gene expression, orchestrating immune responses, and influencing cellular homeostasis. The regulatory potential of noncoding RNA extends to numerous cellular functions, making them a key player in the intricate web of molecular events that govern cell behavior [1].
These noncoding RNA molecules can influence gene expression at multiple levels. MiRNAs, for instance, post-transcriptionally regulate gene expression by binding to messenger RNAs (mRNAs) and triggering their degradation or inhibiting their translation [1]. LncRNAs, on the other hand, have emerged as versatile players that can modulate gene expression through various mechanisms, such as acting as decoys, scaffolds, or guides for protein complexes [2]. CircRNAs, a relatively novel class, have gained attention for their regulatory potential, often acting as sponges for miRNAs and influencing gene expression in intricate ways [3].
The research presented in this review article underscores the profound importance of noncoding RNA regions in the broader context of cellular regulation. In the specific context of HIV/AIDS, understanding how these noncoding RNA molecules interact with the virus, modulate immune responses, and potentially serve as diagnostic or therapeutic targets represents a critical avenue for advancing our knowledge and improving the management of this global health challenge.
The significance of noncoding RNA regions in cellular regulation is a compelling area of investigation that extends well beyond the context of HIV/AIDS, offering insights into fundamental biological processes and the potential for innovative approaches to various diseases.

2. Literature Review

2.1. HIV/AIDS as a Global Health Challenge

Human Immunodeficiency Virus (HIV) infection, leading to Acquired Immunodeficiency Syndrome (AIDS), stands as one of the most significant global health challenges of our time. Since its emergence in the early 1980s, the virus has continued to exact a profound toll on individuals and communities worldwide. Despite notable progress in understanding and managing the disease, HIV/AIDS remains a persistent and complex pandemic, necessitating ongoing research, prevention efforts, and access to care and treatment. The impact of HIV/AIDS extends beyond the realms of health, affecting societies, economies, and the overall well-being of those afflicted. HIV primarily targets the immune system, gradually depleting its function, rendering individuals susceptible to various infections and malignancies [4]. As a result, it has claimed the lives of millions and has left countless others grappling with the consequences of the disease. The global scope of the HIV/AIDS pandemic is staggering, with millions of people living with the virus and millions more having lost their lives to AIDS-related illnesses. In particular, sub-Saharan Africa has borne a disproportionate burden of the disease, but HIV/AIDS is by no means limited to this region. It affects people in virtually every corner of the globe, transcending geographical, cultural, and socioeconomic boundaries [5].
Efforts to combat HIV/AIDS have been multi-faceted and have involved a combination of public health initiatives, scientific research, and global cooperation. Antiretroviral therapy (ART) has revolutionized the management of HIV infection, enabling individuals to lead longer, healthier lives, and reducing the risk of transmission. Preventive measures, including condom use, harm reduction strategies, and pre-exposure prophylaxis (PrEP), have played crucial roles in curbing the spread of the virus [6].
Nevertheless, the challenge of HIV/AIDS persists due to various factors, including stigma, discrimination, limited access to healthcare, and the emergence of drug-resistant strains of the virus. Furthermore, the complex interplay of host factors, viral characteristics, and social determinants continues to complicate our understanding of the disease [7].

2.2. Noncoding RNA in HIV/AIDS Pathogenesis

2.2.1. microRNAs: Post-Transcriptional Regulators of HIV

The complex interplay between noncoding RNA (ncRNA) and HIV/AIDS pathogenesis introduces a multifaceted layer to our understanding of this global health challenge. Within the realm of ncRNA, microRNAs (miRNAs) have emerged as post-transcriptional regulators of HIV, exerting a profound influence on the virus's replication and progression within the host.
MicroRNAs are a class of small RNA molecules, typically around 22 nucleotides in length, which play a central role in the regulation of gene expression. They achieve this by binding to specific messenger RNA (mRNA) molecules and guiding them towards degradation or by inhibiting their translation into functional proteins [8]. In the context of HIV infection, miRNAs have been identified as key players in the intricate dance between the virus and the host.
One of the most well-known examples of miRNA involvement in HIV/AIDS is miRNA-155. This miRNA has been linked to both the regulation of HIV replication and the modulation of immune responses. MiRNA-155 promotes the production of proinflammatory cytokines, which can facilitate viral replication [9]. Simultaneously, miRNA-155 influences the activation of CD4+ T cells, essential targets for HIV infection, and modulates the immune response by regulating various factors, including interferons and chemokines.
MiRNA-29a is another noteworthy player in the miRNA-HIV interaction. This particular miRNA has been found to inhibit HIV replication by targeting the 3' long terminal repeat (LTR) region of the HIV genome. By doing so, it hinders the virus's ability to transcribe its genetic information and effectively reproduce [10].
The exploration of these and other miRNAs in the context of HIV/AIDS pathogenesis has far-reaching implications. Understanding the intricate regulatory roles of miRNAs in HIV replication, immune responses, and disease progression can offer new avenues for therapeutic interventions. Targeting miRNAs with antagomirs or using miRNA mimics may hold promise for controlling viral load and modulating the host's immune response.

2.2.2. Long Noncoding RNAs (lncRNAs): Influencing Gene Expression and Immune Responses

In our exploration of noncoding RNA's role in HIV/AIDS pathogenesis, long noncoding RNAs (lncRNAs) emerge as key players with the capacity to significantly impact gene expression and immune responses. These lncRNAs provide a layer of complexity to the intricate relationship between the virus and the host.
LncRNAs are a diverse class of noncoding RNA molecules typically exceeding 200 nucleotides in length, and they have garnered attention for their ability to influence a wide array of cellular functions, including gene expression and immune responses [11]. In the context of HIV/AIDS, lncRNAs have demonstrated their versatility as regulators that orchestrate responses to viral infection.
One notable example is the lncRNA NEAT1 (Nuclear-Enriched Abundant Transcript 1). NEAT1 has been shown to play a role in the formation of subnuclear structures known as paraspeckles. These paraspeckles are thought to sequester specific cellular proteins and RNA molecules, influencing the host's response to viral infections. In the context of HIV, NEAT1 has been observed to contribute to the regulation of cytokines and interferons, which are essential components of the immune response [12].
Another lncRNA, called MALAT1 (Metastasis-Associated Lung Adenocarcinoma Transcript 1), has also been implicated in HIV pathogenesis. MALAT1 is known for its role in regulating gene expression and splicing, and it has been associated with HIV-1 replication in macrophages. By influencing the expression of key host factors and affecting the splicing of viral RNA, MALAT1 can modulate the course of HIV infection [13].
These examples illustrate the intricate interplay between lncRNAs and HIV/AIDS pathogenesis. LncRNAs not only have the potential to influence viral replication but also to shape the immune responses of the host. This dual role underscores their importance in understanding the dynamics of HIV infection [14].
Furthermore, the study of lncRNAs in the context of HIV/AIDS offers novel insights into potential therapeutic targets. By elucidating the specific lncRNAs that contribute to disease progression, researchers may uncover strategies for modulating these molecules to enhance the host's ability to control viral replication and fortify immune responses [15].

2.2.3. Circular RNAs (circRNAs): Novel Players in HIV Infection

Circular RNAs (circRNAs), a relatively novel class of noncoding RNA molecules, are emerging as intriguing and novel players in the intricate landscape of HIV infection. These circular transcripts have garnered attention for their diverse and often unexpected roles in the regulation of gene expression and the modulation of cellular responses to HIV.
CircRNAs are unique in their structure; they are characterized by covalently closed, single-stranded RNA loops, a feature that sets them apart from the linear RNA counterparts. Within the context of HIV infection, circRNAs have demonstrated their regulatory potential, offering a new layer of complexity to our understanding of the virus-host interactions.
One notable circRNA, circRNA_000744, has been associated with the promotion of HIV replication. This circRNA was found to upregulate the expression of HIV structural proteins, potentially facilitating viral assembly and release. Its presence serves as an illustration of circRNAs as regulatory elements that can enhance viral replication [16].
On the flip side, circRNAs can also act as sponges for microRNAs (miRNAs), effectively sequestering them and limiting their availability for regulating mRNA expression. In this way, circRNAs can indirectly influence the cellular responses to HIV infection by modulating the host's miRNA-mediated regulatory networks [17].
Additionally, circRNAs can also function as templates for the synthesis of proteins, defying the traditional understanding that noncoding RNAs lack protein-coding capacity. This unique attribute further expands the potential impact of circRNAs on HIV pathogenesis, as they may contribute to the production of novel peptides with regulatory functions [18].
The role of circRNAs in HIV/AIDS pathogenesis is still an evolving field of study, and the full extent of their impact remains to be elucidated. Nevertheless, their presence in the realm of noncoding RNA highlights the need for further exploration into the diverse roles they play in HIV infection and the host response.
The exploration of circRNAs in HIV/AIDS offers promising insights into potential therapeutic targets. Understanding how specific circRNAs influence viral replication and the host's immune responses may open doors to innovative interventions, such as circRNA-based therapies or strategies to modulate their functions [19].

2.3. Interactions between Noncoding RNA and HIV

2.3.1. Noncoding RNA-Mediated Regulation of Viral Replication

Noncoding RNA-mediated regulation of viral replication within the context of HIV infection represents a dynamic and complex relationship. These interactions reveal a multifaceted network of noncoding RNAs that impact various stages of the HIV life cycle, from entry and integration to transcription and translation. The involvement of noncoding RNA molecules, such as microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), is instrumental in modulating viral replication and the host's immune responses.
MicroRNAs (miRNAs): MiRNAs play a crucial role in fine-tuning HIV replication. Some miRNAs, like miRNA-29a, directly target the viral RNA genome, leading to reduced viral transcription and translation [20]. Others, such as miRNA-155, impact the host's immune response to HIV infection, potentially influencing the overall viral replication rate [21]. The interplay between these small RNA molecules and HIV provides an additional layer of control and regulation in the ongoing battle between the virus and the host.
Long Noncoding RNAs (lncRNAs): LncRNAs exhibit a wide range of roles in HIV replication. For example, lncRNA NEAT1 has been associated with the regulation of cytokines and interferons, thus affecting the immune responses of the host [22]. Additionally, lncRNA MALAT1 has been linked to HIV-1 replication in macrophages, demonstrating the influence of these noncoding RNAs on viral replication [23]. By shaping the host's immune response and affecting the expression of host factors, lncRNAs contribute to the complex network that regulates HIV replication.
Circular RNAs (circRNAs): CircRNAs are novel players in the realm of HIV infection, and their influence on viral replication is still an evolving field of study. Some circRNAs, like circRNA_000744, have been associated with the promotion of HIV replication by upregulating the expression of viral structural proteins [24]. Others, by acting as miRNA sponges or even serving as templates for protein synthesis, indirectly impact the course of viral replication [25]. The multifaceted roles of circRNAs emphasize the diversity of noncoding RNA in shaping HIV infection dynamics.
The collective impact of noncoding RNAs on HIV replication underscores the complexity of the virus-host relationship. Their regulatory potential spans viral transcription, translation, and the host's immune responses, influencing the progression and control of HIV infection. Understanding these intricate interactions offers promising avenues for future research into innovative therapeutic strategies and a more comprehensive understanding of HIV pathogenesis.

2.3.2. Noncoding RNA Involvement in Immune Evasion and Immune Responses

Noncoding RNA involvement in immune evasion and immune responses within the context of HIV infection highlights the intricate and dynamic interplay between the virus and the host's immune system. Noncoding RNAs, including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), influence various facets of the host's immune responses and the virus's strategies for immune evasion.
MicroRNAs (miRNAs): MiRNAs play a crucial role in the modulation of the host's immune responses to HIV infection. Some miRNAs, such as miRNA-155, influence the host's proinflammatory cytokine production and immune activation [26]. These miRNAs can promote or inhibit immune responses, impacting the host's ability to control viral replication and potentially influencing the disease's progression.
MiRNAs also contribute to HIV's immune evasion strategies. The virus can utilize certain miRNAs to manipulate the host's immune response, potentially suppressing antiviral defenses. This intricate dance between viral miRNAs and the host's miRNA-mediated immune responses represents a critical aspect of HIV pathogenesis.
Long Noncoding RNAs (lncRNAs): LncRNAs have been associated with the modulation of immune responses in the context of HIV infection. For instance, lncRNA NEAT1 has been shown to influence the production of cytokines and interferons, key components of the host's immune response to viral infections [27]. By shaping the host's immune response, lncRNAs contribute to the overall dynamics of the host-virus interaction.
LncRNAs can also play a role in HIV immune evasion. The virus can manipulate host lncRNAs to create an environment conducive to viral replication and evade host immune defenses. Understanding these interactions between HIV and host lncRNAs provides insights into the strategies employed by the virus to evade immune surveillance [28].
Circular RNAs (circRNAs): The involvement of circRNAs in immune evasion and immune responses within HIV infection is a burgeoning area of research. While specific mechanisms are still being elucidated, circRNAs have the potential to modulate the host's immune responses by acting as miRNA sponges or by directly influencing the expression of immune-related genes. These regulatory functions may affect the host's ability to mount effective immune responses against the virus [29].
The interactions between noncoding RNAs and immune evasion in the context of HIV are multifaceted. Understanding how noncoding RNAs influence both the host's immune responses and the virus's strategies for immune evasion is vital in unraveling the complexities of HIV pathogenesis.

2.3.3. Noncoding RNA as Potential Biomarkers for HIV Disease Progression:

The complex interplay between noncoding RNA (ncRNA) and HIV infection extends beyond influencing viral replication and immune responses. Noncoding RNA molecules have shown promise as potential biomarkers for monitoring HIV disease progression and prognosis.
In the context of HIV, identifying reliable biomarkers for disease progression is crucial for early diagnosis, treatment monitoring, and the development of personalized therapeutic strategies. Noncoding RNA molecules, such as microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), have demonstrated the potential to serve as informative biomarkers.
MicroRNAs (miRNAs): Certain miRNAs have been associated with specific stages of HIV disease progression. For instance, the miRNA-21 has been linked to advanced stages of HIV infection and AIDS [30]. Elevated levels of miRNA-21 are indicative of increased immune activation and systemic inflammation, key factors in the progression of the disease.
In addition to miRNA-21, miRNA profiles have been explored to differentiate between HIV infection and control subjects, offering the potential for early diagnosis and monitoring of HIV disease progression. Changes in miRNA expression can provide insights into the dynamics of viral replication and the host's immune responses.
Long Noncoding RNAs (lncRNAs): LncRNAs have also demonstrated potential as biomarkers in HIV disease progression. The lncRNA NEAT1, for example, has been linked to increased expression during HIV infection, suggesting its role in modulating immune responses [31]. Monitoring the expression levels of lncRNAs like NEAT1 may offer insights into the host's immune status and disease progression.
LncRNA profiles have the potential to distinguish between different stages of HIV infection and can be indicative of viral replication and immune responses. As such, lncRNAs may serve as valuable biomarkers for monitoring the evolution of HIV disease.
Circular RNAs (circRNAs): While the role of circRNAs in HIV disease progression is still a developing field, their unique circular structure and potential to function as miRNA sponges suggest their relevance as biomarkers. CircRNAs have the capacity to sequester miRNAs and indirectly influence immune responses and viral replication [32]. Changes in circRNA-miRNA interactions could be indicative of shifts in the host's immune status.

Therapeutic Approach Description Challenges Potential Strategies
MicroRNA (miRNA)-Based Therapies MiRNAs can be manipulated to enhance host defense mechanisms or inhibit viral replication.
  • Ensuring target specificity and avoiding unintended off-target effects.
  • Establishing effective and safe delivery methods for miRNA-based therapies.
  • MiRNA mimics: Delivering synthetic miRNAs targeting viral genes or enhancing host antiviral responses.
  • AntimiRs: Developing oligonucleotides to inhibit miRNAs associated with immune suppression or viral replication.
  • MiRNA-loaded nanoparticles: Using nanoparticles as delivery vehicles to modulate miRNA expression in specific cells or tissues.
Long Noncoding RNA (lncRNA)-Based Therapies LncRNAs are implicated in modulating immune responses and viral replication.
  • Identifying lncRNAs with well-defined roles in HIV pathogenesis.
  • Developing effective drugs or therapeutic agents to target lncRNAs.
  • LncRNA manipulation: Targeting specific lncRNAs to boost antiviral immune responses or inhibit viral factors.
  • Small molecules: Developing drugs to modulate lncRNA expression or function affecting disease progression.
Circular RNA (circRNA)-Based Therapies CircRNAs are emerging players in HIV pathogenesis.
  • Understanding the functions and mechanisms of circRNAs in HIV pathogenesis.
  • Developing safe and effective methods to deliver circRNA-based therapeutics.
  • CircRNA-based antivirals: Developing synthetic circRNAs that act as miRNA sponges to inhibit viral replication.
  • CircRNA-directed therapeutics: Developing drugs or agents to modulate the functions of specific circRNAs.
Additional Considerations
  • Regulatory approval, safety, and ethical considerations are crucial.
  • Personalized medicine potential based on unique noncoding RNA profiles.
