SARS-CoV-2 spike-driven reactivation of latent herpesviruses as a mechanistic link to post-viral diseases

Jana, Manoj K.; Nora-Krukle, Zaiga; Prusty, Bhupesh K.

Significance​

Persistent symptoms following viral infections are increasingly recognized, yet the biological mechanisms driving long-term disease remain poorly defined.
Emerging evidence suggests that the severe acute respiratory syndrome coronavirus 2 spike protein can perturb innate immune signalling and cellular metabolism, conditions known to disrupt herpesvirus latency.
We propose that spike-induced immune-metabolic stress may facilitate the reactivation of neurotropic herpesviruses such as human herpesvirus 6, human herpesvirus 7, and Epstein–Barr virus, thereby sustaining immune dysregulation and cellular dysfunction.
This virus–virus interaction framework provides a plausible mechanistic explanation for the biology of chronic post-viral disease and highlights herpesvirus reactivation as a potential target for biomarker development and therapeutic intervention.

Abstract​

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is increasingly associated with long-term biological perturbations that persist beyond the acute phase of the disease.
In this review, we examine the evidence that spike-induced immune and metabolic remodelling facilitates the reactivation of latent neurotropic herpesviruses, particularly human herpesvirus 6 (HHV-6), HHV-7, and Epstein–Barr virus, amplifying immune dysregulation through viral proteins and host–pathogen interactions that perturb mitochondrial function, innate immune responses, and neuroimmune communication.
We discuss how this virus–virus interaction represents a biologically plausible pathway linking chronic SARS-CoV-2 infection to downstream cellular dysfunction.
By integrating emerging evidence on spike persistence with established principles of herpesvirus latency biology, we argue that herpesvirus reactivation serves as a mechanistic consequence of SARS-CoV-2 infection.
Understanding how the spike protein perturbs cellular homeostasis and triggers latent virus reactivation may reveal biomarkers of reactivation and inform targeted therapeutic strategies to interrupt this cascade in post-infectious disease states.

Excited to share our new review article in Trends Open discussing a provocative and clinically important question: can the SARS-CoV-2 spike contribute to the reactivation of latent herpesviruses and thereby shape post-viral chronic diseases such as Long COVID and ME/CFS?
In this review, we discuss how persistent spike-related immune signaling, inflammatory stress, mitochondrial dysfunction, and herpesvirus latency escape may intersect in susceptible patient subgroups. We also highlight why integrated viral, immune, and metabolic biomarkers will be essential for moving from broad clinical labels toward mechanism-based patient stratification.
We hope this article stimulates further discussion, experimental validation, and clinically focused studies on viral persistence, herpesvirus reactivation, and targeted therapeutic approaches in Long COVID and ME/CFS. Thanks to the coauthors (Manoj Kumar Jana, Zaiga Nora-Krukle), the entire team of PrustyLab, the RSU Institute of Microbiology and Virology, and Rīga Stradiņš University for the support. We also appreciate the Latvian Council of Science for funding this crucial project.
