Compared with baseline, genital HSV-2 shedding rates immediately after dosing were reduced with GEN-003 (from 13.4% to 6.4% for 30 μg [.)Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted pathogen that often causes recurrent genital lesions.Transmission occurs largely from asymptomatic genital tract virus shedding, making this a key target for a therapeutic HSV vaccine.
There are many implications, and we’ve only scratched the surface.
Genital herpes simplex virus type 2 (HSV-2) infection causes recurrent lesions and frequent viral shedding.
“These nerve cells represent a stable place in which a latent virus can remain unperturbed for years,” explains study coauthor Moses V.
Chao, Ph D, professor of cell biology, and neuroscience and physiology.
The management of genital herpes currently includes episodic or daily suppressive therapy with nucleoside analogues, which abrogates most recurrences but only partly reduces viral shedding and transmission [1, 2].
GEN-003 contains a transmembrane deletion mutant of glycoprotein D (g D2ΔTMR), a primary target antigen for neutralizing antibody and T cells, combined with a large fragment of infected cell protein 4 (ICP4.2), an HSV-2 T-cell antigen prioritized through human T-cell screens.But how viruses emerge from this sanctuary has been poorly understood, in part because it’s difficult to study ganglion cells in isolation.“The ganglion is like a miniature organ,” explains Dr. “It contains many different types of cells, including immune cells.” The researchers’ solution was an innovative culturing technique “made of nothing but neurons,” says Dr. “It allows us to study the molecular signaling and circuitry in depth, without interference from other cells.” With a clear window onto the infected cells, the researchers made a startling discovery: when jostled awake by stress, HSV-1 bursts into action, releasing a flood of proteins that jams the host’s immune reaction to interferon signals from infected cells, effectively disarming the cells’ alarm system.Participants obtained genital swab specimens twice daily for HSV-2 detection and monitored genital lesions for 28-day periods at baseline and at intervals after the last dose.One hundred and thirty-four persons received all 3 doses.Now, a multidisciplinary research team at NYU Langone Health has discovered how the virus evades the immune system—a critical discovery that paves the way for novel therapies to treat and potentially eradicate HSV-1 and other herpes viruses.Infectious viruses engage in a kind of molecular arms race with the immune system, as both invader and host compete to take the lead.If all goes well for the host, the immune system eventually overwhelms the virus and eliminates it.But some viruses, including herpes simplex viruses, have evolved a clever tactic to linger on: a hibernation state known as viral latency, which allows viruses to lie dormant in a host’s cells, out of sight of the immune system.These medications block the virus from replicating, which can eliminate symptoms of infections, but they are not a cure.“The holy grail of this research is to one day eradicate latency either by getting the virus out or sealing it up permanently,” says Dr. “Understanding all the interactions between viruses and hosts could yield findings that result in better treatments for a number of viral diseases.
