Archana Joon is a postdoctoral researcher at Albert Einstein College of Medicine. Her work focuses on how herpes simplex virus (HSV) alters local immune environments to promote HIV persistence and acquisition. In this interview, she discusses her passion for biology and how it guided her current research focus.
Biological Interconnections and Host Immune Reshaping
Q | What scientific problem are you trying to solve?
I am investigating the HSV/HIV syndemic—the complex interaction between these two viruses and how they exacerbate each other’s health impacts. HSV-2 is highly prevalent among people living with or at risk for HIV, increasing both susceptibility to and transmission of HIV. Mechanisms such as genital ulcers, inflammation, and immune cell recruitment can facilitate HIV entry and replication. Conversely, HIV-induced immune suppression can heighten the frequency and severity of HSV outbreaks. Understanding this syndemic is crucial because it reveals how co-occurring infections amplify disease burden beyond the sum of their individual effects. My objective is to identify the biological factors driving this syndemic and uncover opportunities for prevention, treatment, and improved health outcomes.
Q | What drew you to immunology?
I was drawn to this field by a fascination with the intersection of biology, lived experience, and health inequities. Working with samples from women has provided a unique lens into questions that are scientifically complex yet deeply human. As I explored the relationship between HSV and HIV, I became invested in understanding them not as isolated infections, but as a syndemic that reinforces itself, often disproportionately impacting vulnerable populations.
What motivates me most is the opportunity to uncover mechanisms that could improve women’s health. Handling patient samples makes the research tangible; behind every dataset is a person whose life is affected by these infections. This perspective has cemented my commitment to studying the immune responses linking HSV and HIV to generate knowledge that informs better prevention and care. For me, research is most meaningful when it bridges fundamental science with real-world impact, and this field allows me to do both.
Q | What’s one thing you learned from your research that you didn’t expect?
I was surprised by how dynamic and interconnected the immune system truly is. Initially, I viewed HSV and HIV as separate viral infections. However, I discovered the profound extent to which one pathogen can reshape the immune environment to influence the other.
Through studying the HSV/HIV syndemic, I learned that HSV is not merely a co-occurring infection; it can sustain immune activation and alter the immune cell populations targeted by HIV. Subtle shifts in the local immune environment can significantly impact susceptibility, viral persistence, and disease progression. This shifted my perspective from viewing individual pathogens to understanding the immune system as a complex ecosystem where interactions are as critical as the pathogens themselves.
This insight deepened my interest in immunology because it highlighted how much remains to be discovered about host-pathogen interactions and how understanding these mechanisms can lead to more effective prevention and treatment strategies.
Future Directions in Latency and Viral Reservoirs
Q | If your research succeeds, what could it change for science or society?
This work could deepen our understanding of how HSV shapes the immune responses that influence HIV acquisition and persistence. By identifying the mechanisms that link these infections, we may discover new targets for prevention and therapeutic interventions. More broadly, it could inform strategies that address both infections concurrently rather than in isolation, ultimately improving outcomes for patients disproportionately affected by the HSV/HIV syndemic.
Q | What question are you most excited to answer next?
I am eager to determine whether HSV-driven immune signaling can be leveraged to reverse HIV latency and expose hidden viral reservoirs. By understanding how these pathways influence HIV persistence, we may uncover new strategies to target the reservoir—the greatest barrier to achieving a cure.
