Solutions for Herpesviruses Vaccines Development

Background

Human herpesviruses are distributed worldwide, and more than 90% of adults are infected by one or multiple HHVs. The HHV family contains three sub-families: the alpha sub-family [herpes simplex virus 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV)], beta sub-family [human cytomegalovirus (HCMV), HHV6, and HHV7)], and gamma sub-family [Epstein-Barr virus (EBV) and Kaposi’s sarcoma–associated herpesvirus (KSHV)]. All the viruses typically establish latent infection in host, and undergo lytic reactivation in certain pathophysiological conditions[1], which has brought serious burden to human health. Therefore, it is urgent to develop effective prevention and treatment drugs against human herpesvirus.

Varicella-zoster virus (VZV)highly contagious enveloped DNA virus that is common in children. The initial infection causes chickenpox in children, and the virus remains latent in the body after recovery. In a few patients, the virus recurs in adults and causes herpes zoster.
VZV virus contains six glycoproteins, gE, gB, gH, gI, gC and gL.  In infected cells, gE is the most abundant protein expressed by VZV and plays an important role in viral replication and cell-to-cell transmission. As a recognizable antigen, gE becomes a target for vaccine research.

Millions of people worldwide are exposed to herpes simplex virus(HSV) annually. Post-exposure, the virus may remain asymptomatic or cause mild to life threatening complications. HSV can be broadly divided into two serotypes: HSV-1 and HSV-2. HSV-1 and HSV-2 belong to the alpha-herpesvirus subfamily, which generally has a short replicative cycle and is capable of infecting broad range of hosts.
Mature HSV is covered by an envelope that expresses at least 12 different glycoproteins: gB, gC, gD, gE, gG, gH, gI, gJ, gK, gL, gM, and gN on their surface, in distinct shapes and sizes. Some exist as heterodimers (gH/gL and gE/gI), while most exist as monomers.
Viruses attach to cell surface receptors heparan sulfate proteoglycan (HSPGs) of the host via viral glycoproteins gB and/or gC. Glycoproteins gD, gH/gL, and gB bind to cell membrane receptors that subsequently trigger membrane fusion. Cell membrane receptors using gD, gH/gL, and gB glycoproteins triggers direct membrane fusion. As such, Glycoprotein gD is a common target of host cellular humoral and cellular immunity, as such, remains an important target for vaccine design.

Epstein-Barr virus (EBV) is a ubiquitous member of the γ-herpesvirus subfamily, which establishes lifelong latency in 95% of the human population. EBV infections during childhood and adolescence are usually asymptomatic but may cause infectious mononucleosis (IM). As an oncogenic virus, EBV is associated with approximately 200,000 new cases of malignancies and causes 140,000 deaths each year worldwide. However, effective vaccines and therapeutics against EBV infection remain unavailable.
EBV enters epithelial cells at the plasma membrane, but endocytosis is needed for B cell infection. B cell entry is initiated by gp350/gp220 binding to the complement receptor-2 (CR2) or to CR1, and then gHgL/gp42 binds to HLA-II to trigger pre-fusion gB. During entry into epithelial cells, BMRF2 binds to integrins and then gHgL binds to EphA2 to activate pre-fusion gB. Glycoprotein B (gB) is the primary fusogen essential for EBV entry into host cells. gH/gL and gB proteins coordinate to mediate EBV fusion and entry into B cells and epithelial cells, suggesting that inoculation with these proteins may trigger antibodies that prevent EBV infection.

Human cytomegalovirus (HCMV) infection, the most common cause of congenital disease globally, affecting an estimated 1 million newborns annually, can result in lifelong sequelae in infants, such as sensorineural hearing loss and brain damage. Hence, an effective HCMV vaccine is urgently needed to prevent infection and HCMV-associated diseases.
HCMV infection causes persistent, life-long infection in broad types of host cells mediated by four major envelope glycoprotein complexes (GCs): glycoprotein B (gB) oligomer, gM/gN dimer, gH/gL/gO trimer, and gH/gL/UL128/UL130/UL131A pentamer complex (PC) through distinct entry mechanisms. gB is essential for HCMV viral fusion and is required for entry into all permissive cell types and for cell-to-cell spread, has been identified as one of the major vaccine targets due to its ability to elicit both NAb and non-NAb responses. HCMV gH/gL/gO trimer was demonstrated to promote gB fusion on all cell types. Hence, gH/gL/gO trimer is a potential target for HCMV vaccine and potentially preventing HCMV from escaping current clinically tested vaccine-elicited NAbs.

Frequently Asked Questions

Among the numerous HSV antigens (such as gH & gL, gC, gD, gE, gB, etc.), which one is best target for vaccine development?

gB, as the most conserved fusion glycoprotein, plays a crucial role in driving the fusion of the viral envelope with the host cell membrane. gC and gB work synergistically to help concentrate viral particles on the surface of host cells. gD can specifically bind to host cells, while the gH/gL heterodimer can facilitate signaling, promoting the fusion of the viral envelope with the host cell membrane. In selecting candidate vaccine targets, one can choose based on their specific research focus and the characteristics of the antigen proteins.

How can the stability of test kit results be ensured?

All commercially available test kits undergo methodological validation based on the 9012 Guidelines for Quantitative Analysis of Biological Samples to ensure the stability of the test results.

For antigen quantitative detection test kits, can custom standards be used to replace the standard provided in the kit for quantification?

Replacement is possible, but you will need to conduct methodological validation and explore the quantitative range using your own standards.

What are the key differences between the VZV gE protein antigen quantitative detection kits RAS-A185 and RAS-A102?

RAS-A185 and RAS-A102 kits differ in sensitivity and colorimetric methods. The RAS-A185 uses HRP-Anti-Glycoprotein E (VZV) antibody for direct color development, while RAS-A102 employs Biotin-Anti-Glycoprotein E (VZV) antibody plus Streptavidin-HRP for color development. Both can be used for quantitative detection of VZV gE protein, but RAS-A102 has higher sensitivity, allowing you to choose the appropriate kit based on protein expression levels.
