Abstract
Three-dimensional (3D) human tissue models/microphysiological systems (e.g., organs-on-chips, organoids, and tissue explants) model HIV and related comorbidities and have potential to address critical questions, including characterization of viral reservoirs, insufficient innate and adaptive immune responses, biomarker discovery and evaluation, medical complexity with comorbidities (e.g., tuberculosis and SARS-CoV-2), and protection and transmission during pregnancy and birth. Composed of multiple primary or stem cell-derived cell types organized in a dedicated 3D space, these systems hold unique promise for better reproducing human physiology, advancing therapeutic development, and bridging the human-animal model translational gap. Here, we discuss the promises and achievements with 3D human tissue models in HIV and comorbidity research, along with remaining barriers with respect to cell biology, virology, immunology, and regulatory issues.

Abstract
Human cytomegalovirus (HCMV) is one of the main causes of serious complications in immunocompromised patients and after congenital infection. There are currently drugs available to treat HCMV infection, targeting viral polymerase, whose use is complicated by toxicity and the emergence of resistance. Maribavir and letermovir are the latest antivirals to have been developed with other targets. The approval of letermovir represents an important innovation for CMV prevention in hematopoietic stem cell transplant recipients, whereas maribavir allowed improving the management of refractory or resistant infections in transplant recipients. However, in case of multidrug resistance or for the prevention and treatment of congenital CMV infection, finding new antivirals or molecules able to inhibit CMV replication with the lowest toxicity remains a critical need. This review presents a range of molecules known to be effective against HCMV. Molecules with a direct action against HCMV include brincidofovir, cyclopropavir and anti-terminase benzimidazole analogs. Artemisinin derivatives, quercetin and baicalein, and anti-cyclooxygenase-2 are derived from natural molecules and are generally used for different indications. Although they have demonstrated indirect anti-CMV activity, few clinical studies were performed with these compounds. Immunomodulating molecules such as leflunomide and everolimus have also demonstrated indirect antiviral activity against HCMV and could be an interesting complement to antiviral therapy. The efficacy of anti-CMV immunoglobulins are discussed in CMV congenital infection and in association with direct antiviral therapy in heart transplanted patients. All molecules are described, with their mode of action against HCMV, preclinical tests, clinical studies and possible resistance. All these molecules have shown anti-HCMV potential as monotherapy or in combination with others. These new approaches could be interesting to validate in clinical trials.

[PMID: 37393055 DOI: 10.1016/j.antiviral.2023.105661] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/26/2023] [Accepted: 06/28/2023] [Indexed: 07/03/2023]
Abstract
INTRODUCTION Hyperimmune globulin Cytotect CP® is a candidate for cytomegalovirus congenital infection prevention. We previously demonstrated its efficacy to prevent villi infection in our first-trimester placenta explants up to day 7, but with an inefficiency at day 14 (Coste-Mazeau et al., Microorganisms, 2021). As this could impact clinical efficacy, we now study the effect of weekly administration of Cytotect CP® on the prevention of villi infection. METHODS Human embryonic lung fibroblast cells were infected at confluence with the endothelial strain TB40/E. Placentae were collected from voluntary pregnancy terminations (8-14 weeks of gestation) from cytomegalovirus-seronegative women. After 5 days of infection of the cells, villi explants were simultaneously added on sponges with Cytotect CP® at various concentrations. After 7 days, Cytotect CP® was renewed in only half of the plates. Villi were collected at days 7 and 14 with or without medium renewal. We compared the viral load by duplex quantitative PCR cytomegalovirus/albumin and the toxicity by measuring β-hCG concentrations in the supernatants with and without medium renewal. RESULTS We did not find any efficacy of Cytotect CP® at day 14 when Cytotect CP® is not renewed, but a regular decrease of the viral load when the immunoglobulins were renewed at day 7, with an EC50 = 0.52 U/mL. We did not observed toxicity of Cytotect CP® with or without renewal of the molecule. CONCLUSION Cytotect CP® is more effective when renewed at day 7. The prevention of congenital cytomegalovirus infection could be enhanced by reducing the spacing of doses.

Abstract
Human cytomegalovirus (HCMV) is an important pathogen worldwide. Although HCMV infection is often asymptomatic in immunocompetent individuals, it can cause severe or even life-threatening symptoms in immunocompromised patients. Due to limitations of antiviral treatments, it is necessary to search for new therapeutic alternatives. Recent studies have highlighted the contribution of antibodies in protecting against HCMV disease, including neutralizing and non-neutralizing antibodies. Given the immunocompromised target population, monoclonal antibodies (mAbs) may represent an alternative to the clinical management of HCMV infection. In this context, we provide a synthesis of recent data revising the literature supporting and arguing about the role of the humoral immunity in controlling HCMV infection. Additionally, we review the state of the art in the development of therapies based on mAbs.
