Human Cytomegalovirus (HCMV)
Human cytomegalovirus (HCMV) is a β-herpesvirus, also known as human herpes virus 5. Compared with other human herpesviruses, the prevalence of HCMV is high, and more than 90% of the general population is an HCMV carrier. HCMV infection can disrupt homeostasis by affecting the host cell autophagy, apoptosis, proliferation, invasion, angiogenesis, and immune response . Increasing evidence indicates that HCMV causes the occurrence and progression of inflammation , atherosclerosis, Crohn’s disease, and various cancers. More seriously, HCMV can trigger life-threatening diseases in immunosuppressed individuals. Thus, it is necessary to elucidate the pathogenic mechanism of HCMV and discover novel targets and strategies for anti-HCMV treatment. Apoptosis is a form of programmed cell death, which is essential for maintaining normal physiology and tissue function by cleaning up cells that are damaged, dysfunctional, or no longer necessary. The survival and accumulation of damaged or unnecessary cells contribute to numerous diseases, such as cancers, in addition to immunological, neurodegenerative, cardiovascular, and infectious diseases. Apoptosis generally occurs through two distinct pathways: intrinsic and extrinsic. Interestingly, both extrinsic and intrinsic apoptotic pathways can be activated by pathogenic infection.
1. The Prevalence and Perniciousness of HCMV
Cytomegalovirus was first isolated by Smith and Rowe in 1956  and, in 1990, Chee et al. reported the annotated draft of the HCMV genome . Recent research shows that HCMV consists of double-stranded linear DNA. The HCMV genome is 236 kb, which can encode 167 genes and translate more than 750 open reading frames . Most of the genetic products are strongly correlated to HCMV infection and prevalence. The major transmission routes of HCMV include saliva, semen, urine, placental transfer, breastfeeding, blood transfusion, organ transplantation, and hematopoietic stem cell transplantation . Because of these numerous routes, HCMV has easily spread globally, and approximately 100% of adults in developing countries are carriers .
Clinically, most of those (approximately 90%) who develop a primary HCMV infection are symptomless, and only a few people show symptoms such as asthenia, headache, chills, fever, and sweating . However, HCMV can infect most cell types/organs and results in more morbidity and mortality compared to any other herpes virus. HCMV infection is seriously life-threatening to immunocompromised patients, organ transplantation patients, and patients undergoing chemotherapy . Congenital infection often leads to serious complications, including visual disorders, sensorineural deafness, neurodevelopmental impairment, developmental delay, and epilepsy . Moreover, several studies have shown that HCMV infection causes the occurrence and progression of several chronic diseases, including autoimmune disease (AID) , tuberculosis , atherosclerosis , mental disorders , age-related macular degeneration (AMD) , pneumonitis, and myocarditis . In particular, many studies have revealed that HCMV infection is related to various cancers, such as cervical cancer , breast cancer , colorectal cancer , ovarian cancer , prostate cancer , squamous cell carcinoma , lymphoma , glioblastoma , medulloblastoma , and neuroblastoma , as well as poor outcomes. A list of HCMV-related diseases is provided in Figure 1.

During HCMV infection, a large number of proteins are expressed, which interfere with the normal physiological activity of host cells and ensure HCMV replication . Studies have reported that HCMV infection can significantly affect the expression profile of cytokines  and disrupt intracellular calcium and adenylate triphosphate homeostasis , affecting cell differentiation , apoptosis , proliferation, and migration . Most importantly, apoptosis disorder induced by HCMV infection is strongly associated with the pathogenesis of numerous diseases.
2. HCMV Causes Numerous Diseases by Inducing Apoptosis Disorder
Cell death, or apoptosis, is considered the first line of defense and a key defense mechanism against viral infection due to the fact that it inhibits the spread of infection from infected to uninfected cells. HCMV is a slow-replicating virus, which has evolved and acquired anti-apoptotic genes . These genes encode several apoptosis inhibitors, such as pUL38 and UL138, which allow them to abrogate apoptosis to ensure HCMV replication . Apoptosis disorder results in numerous diseases.
2.1. Immune System Diseases
AID is a complex disorder of the immune function caused by both genetic and environmental factors. HCMV is a key pathogen and plays a critical role in the onset and progress of AID by regulating the apoptosis of its host cells .
2.1.1. Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is a chronic, systemic autoimmune disease, with a prevalence of 0.3 to 23.2 cases per 100,000 . HCMV is one of the environment-related pathogenetic factors of SLE and contributes to the development of SLE. HCMV US31, UL55, and pp65 may play a vital role in the development of SLE by causing abnormal cellular events in its host cells . One such event is apoptosis, which is considered to be involved in the pathogenesis of SLE. Neo et al. revealed that viral antigen UL44 is redistributed to the cell surface during HCMV-induced apoptosis and then accelerates the development of SLE . These results suggest that apoptosis induced by HCMV infection is significantly associated with the progression of SLE.
2.1.2. Systemic Sclerosis
Systemic sclerosis (SSc) is mainly characterized by skin involvement that often affects multiple organ systems . Among the numerous pathogenetic factors, HCMV is the key factor enhancing the progress of SSc . Evidence shows that HCMV UL83 and UL94 are associated with SSc . Arcangeletti et al. indicated that HCMV-specific CD8+ T cells play an important role in the development of SSc . Pastano et al. pointed out that HCMV infection induces both endothelial cell apoptosis and fibroblast proliferation, promoting the progress of SSc . These results show that HCMV infection causes the development of SSc by regulating the apoptosis and proliferation of its host cells.
Acute interstitial pneumonia (AIP) is an idiopathic pulmonary disease that can cause rapid, progressive dyspnea and respiratory failure. HCMV is a key pathogenetic factor of AIP. Chen et al. reported that HCMV infection disrupts lung fibroblast proliferation and apoptosis by regulating the WNT signaling pathway and leads to AIP . In addition, Maidji et al. revealed that HCMV replication triggers apoptosis and inhibits the production of surfactant proteins in the alveolar epithelium, finally resulting in pneumonia and acute lung injury . These findings highlight the critical role of apoptosis induced by HCMV infection in the occurrence and development of pneumonia.
Atherosclerosis is still one of the main causes of death in both developed and developing countries . One of the main pathogenetic factors of atherosclerosis is apoptosis disorder induced by HCMV infection. Studies have reported that HCMV infection can activate atherosclerosis-relevant factors involved in atherosclerotic plaque rupture and myocardial infarction . Tanaka et al. revealed that HCMV immediately-early 2 (IE2)-84 viral protein abrogates p53-mediated apoptosis and leads to smooth muscle cell accumulation, thereby contributing to restenosis and atherosclerosis . Fan et al. indicated that HCMV-miR-US25-1 levels are upregulated in its host cells, and that deteriorates oxidized low-density lipoprotein induced the apoptosis of endothelial cells, promoting the development of atherosclerosis . Furthermore, HCMV-derived proteins US28 and UL122 induced endothelial cell damage and apoptosis, which accelerated the process of atherosclerosis . These results imply that HCMV causes the apoptosis of endothelial cells and contributes to the initiation and progression of atherosclerosis.
Compared with the diseases discussed above, cancer is more strongly linked to apoptosis disorder induced by HCMV infection. Increasing evidence indicates that the products of the HCMV genome cause the dysregulation of apoptosis and are involved in the oncogenesis , for example, glioblastoma , breast cancer , and leukemia .
Glioblastoma is the most common and malignant tumor. It occurs primarily in the nervous system and has a high morbidity rate. Studies have reported that HCMV infection contributes to the development of glioblastoma by interfering with apoptosis. Liang et al. revealed that HCMV-miR-UL112-3p enhances the proliferation, clone formation, migration, and invasion and suppresses the apoptosis of glioblastoma cells by targeting and downregulating tumor suppressor candidate 3 and then accelerates the progression of glioblastoma . Furthermore, HCMV infection suppressed the apoptosis of glioblastoma cells by increasing the expression level of activating transcription factor 5 (ATF5) and the B cell lymphoma/leukemia-2 (Bcl-2)-to-Bcl-2-associated X (BAX) protein ratio . These results indicate that HCMV infection promotes the development of glioblastoma by suppressing apoptosis.
Neuroblastoma is a pediatric cancer entity strongly associated with HCMV infection. Studies have reported that HCMV infection protects neuroblastoma cells from cytotoxic-agent-induced apoptosis, which might result in the failure of therapy in some neuroblastoma patients .
2.4.3. Breast Cancer
Breast cancer is the most common cancer affecting women worldwide . HCMV infection is one of the key factors contributing to the progression of breast cancer. Valle Oseguera et al. reported that cmv interleukin 10 (IL-10) can bind to the IL-10 receptor of breast cancer cells and can then activate the signal transducer and activator of transcription 3 (STAT3), which protect breast cancer cells from etoposide-induced apoptosis and also promote cancer cell proliferation .
2.4.4. Acute Myeloid Leukemia
Acute myeloid leukemia is a group of heterogeneous diseases that is only cured in a small number of patients . Unlike its carcinogenesis in other types of cancers, HCMV can significantly suppress the proliferation of acute myeloid leukemia cells, enhance the expression of HLA-class-II-molecules, and increase apoptosis .
2.4.5. Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) accounts for 70–90% of primary liver cancer diagnoses and is one of the most common malignancies worldwide . To date, there is no effective therapy for advanced HCC. Kumar et al. revealed that HCMV could provide antitumoral effects in a murine model of HCC. HCMV infection restricted cellular proliferation and enhanced apoptosis by inhibiting the activation of the STAT3-cyclin D1 signaling pathway . In contrast, Lepiller pointed out that HCMV induces the expression of IL-6 and then activates the IL-6R-Janus kinase (JAK)-STAT3 pathway, which results in the up-regulation of cyclin D1 and survivin. All of these cytokines enhance cancer cell proliferation and colony formation, and finally, accelerate the development of HCC .
2.4.6. Gastric Cancer
As one of the most prevalent gastrointestinal diseases, gastric cancer (GC) is the main cause of cancer-related deaths worldwide. Unfortunately, most patients are detected at the advanced stage of the disease and lose any chance of recovery . Chen et al. reported that HCMV UL138 can act as a tumor inhibitor in GC. UL138 inhibits GC cell viability and induces apoptosis by interacting with heat shock protein 70 (HSP70), suppressing the progression of GC .
Overall, apoptosis disorder is strongly linked to numerous diseases. After infection, the products of the HCMV genome lead to abnormal apoptosis, which contributes to or suppresses the development of diseases. These findings reveal that regulating the apoptosis of host cells may provide a novel therapeutic strategy for HCMV-related diseases.
3. Molecular Mechanism of Apoptosis Mediated by HCMV Infection
The mechanism underlying the induction of apoptosis by HCMV infection is quite complex. The products of the HCMV genome disrupt the normal physiological activities of its host cells and then result in apoptosis disorder by mediating both extrinsic and intrinsic signaling pathways. The extrinsic pathway mainly involves special death receptors by activating inward signals. Unlike the extrinsic pathway, the intrinsic pathway depends on intracellular organelles, such as the mitochondria and the endoplasmic reticulum (ER) . The apoptotic signaling pathways and key effector genes/proteins regulated by HCMV infection are shown in Figure 2 and Table 1.
Figure 2. Apoptotic signaling pathways regulated by HCMV infection. A diagram of apoptotic signaling pathways induced (↑) or inhibited (T) by HCMV infection. IE2: immediately-early 2 protein; c-FLIP: cellular FLIP; FASL: Fas cell surface death receptor (FAS) ligand; FADD: FAS-associated death domain; TRAIL: TNF-related apoptosis-inducing ligand; TRAIL-R: TNF-related apoptosis-inducing ligand receptor; TNF: tumor necrosis factor; TNF-R1: tumor necrosis factor receptor 1; TRADD: TNF receptor-1-associated death domain; PEA-15: phosphoprotein enriched in astrocytes-15; cIL-10: cellular interleukin 10; vICA: viral inhibitor of caspase-8 activation; Bax: BCL2-associated X protein 2; Bak: BCL2 homologous antagonist killer; JNK: c-Jun N-terminal kinase; ERN1: endoplasmic-reticulum-to-nucleus signaling 1; USP24: ubiquitin-specific protease 24; NCOA4: nuclear receptor coactivator 4. This figure was created on Biorender.com.
Table 1. The summary of effector gene/proteins regulated by HCMV.
3.1. Extrinsic Pathway
The extrinsic apoptotic pathway mainly includes extracellular ligands and death receptors, such as tumor necrosis factor receptor 1 (TNF-R1), TNF-related apoptosis-inducing ligand receptor (TRAIL-R), and Fas cell surface death receptor (FAS) . Ligands bind with death receptors, which leads to the formation of a death-inducing signaling complex (DISC), and consequently caspase activation, eventually followed by apoptosis .
Studies have reported that HCMV infection can evade cell death through the extrinsic apoptotic pathway. FAS played a critical role in the clearance of virus-infected cells by mediating apoptosis. HCMV infection suppressed the cell surface expression of FAS and, consequently, protected infected cells against FAS-mediated apoptosis . Studies have also reported that HCMV inhibits p73-dependent FAS-mediated apoptosis and contributes to the survival of its host cells . Poole et al. demonstrated that cellular IL-10 (cIL-10) is a key survival factor that can upregulate phosphoprotein enriched in astrocytes-15 (PEA-15) and then protect CD34+ progenitor cells from FAS-mediated apoptosis .
HCMV protein IE2 activated cellular FLIP (c-FLIP), which suppressed the activation of caspase-8 and caspase-3 by decreasing the FAS ligand (FASL) in HCMV-infected human retinal cells. Meanwhile, IE2 played a key role in resistance to TRAIL-mediated cell death through the phosphatidylinositol 3-kinase (PI3K) pathway .
The viral inhibitor of caspase-8 activation (vICA) is conserved in both HCMV and murine cytomegalovirus (MCMV). Chaudhry et al. revealed that vICA prevents death-receptor-induced apoptosis by inhibiting the activation of caspase-8 and pro-apoptotic signaling . Similarly, McCormick et al. indicated that, in response to infection, vICA can inhibit the activation of both caspase-dependent and caspase-independent apoptotic pathways . Moreover, HCMV pUL36 is regarded as a multifunctional inhibitor that can degrade mixed-lineage kinase domain-like protein (MLKL), prevent proteolytic activation of procaspase-8, and then suppress both necroptosis and apoptosis during HCMV infection .
In contrast, Chien et al. revealed that MCMV-infected eyes show significant amounts of TNF-α, TNF receptors 1 and 2, active caspase-8 and caspase-3, TRAIL, TRAIL-R, FAS, and FASL. In addition, MCMV-infected eyes also upregulate the expression of receptor-interacting protein (RIP1, RIP3), caspase-1, IL-1β, and IL-18. These results demonstrate that apoptosis, necroptosis, and pyroptosis are activated and participate in the development of MCMV-related retinal disease .
3.2. Intrinsic Pathway
The intrinsic apoptotic pathway responds to death stimuli, such as DNA damage, chemotherapeutic agents, serum starvation, and viral infection. The intrinsic pathway depends on organelle dysfunction; for instance, ER stress, lysosomal dysfunction, and mitochondrial dysfunction all trigger apoptosis .
Studies have reported that HCMV promotes the survival of human embryonic lung fibroblasts by activating the mitogen-activated protein kinase/extracellular-regulated protein kinase (MAPK/ERK) signaling pathway. BCL2-associated athanogene 1 (Bag-1) was upregulated in a MAPK/ERK-dependent fashion and was indispensable suppression of apoptosis in HCMV-infected cells . In contrast, HCMV infection induced human retinal pigment epithelium cell apoptosis by activating caspase-3 and the poly ADP-ribose polymerase (PARP) pathway, which caused severe visual impairment . Dou et al. pointed out that HCMV infection reduces the viability of megakaryocytes by promoting caspase-3-dependent apoptosis via the activation of the c-Jun N-terminal kinase (JNK) signaling pathway . More interestingly, HCMV infection had antitumoral effects by activating the intrinsic apoptotic pathway. HCMV restricted HepG2 cell proliferation decreased colony formation and enhanced intrinsic apoptosis by activating caspase-9 and caspase-3 .
3.2.1. Mitochondrial Pathway
The mitochondria play a prominent role in metabolism, as well as being involved in the regulation of apoptosis. Due to different stresses, such as viral infection, apoptosis-related proteins transfer to the mitochondria and further activate and initiate mitochondrial apoptosis. Zhang et al. described a novel anti-apoptotic mechanism of HCMV infection. HCMV pUL37x1 was the potent viral mitochondrion-localized inhibitor of apoptosis (vMIA). vMIA retargeted Bax to the mitochondrion-associated membrane and resulted in increased ubiquitination and proteasome-mediated degradation of Bax, which enhanced the survival of infected cells .
3.2.2. Endoplasmic Reticulum Pathway
The endoplasmic reticulum is the center where proteins are modified and folded and where calcium is stored. Endoplasmic reticulum dysfunction promotes the occurrence of apoptosis. During HCMV infection, the ataxia telangiectasia mutant contributed to the activation of p53, and p53 further stimulated Bax and Bak expression, as well as caspase-3 activation, resulting in human aortic endothelial cell (HAEC) dysfunction and apoptosis . Studies have reported that HCMV protein pUL38 prevents cell death by maintaining calcium homeostasis in the endoplasmic reticulum . Moreover, HCMV employs its microRNA against intrinsic apoptosis. Babu et al. indicated that miR-UL70-3p and miR-UL148D could potentially target the pro-apoptotic gene endoplasmic-reticulum-to-nucleus signaling 1 (ERN1) and then suppress the initiation of endoplasmic-reticulum-stress-induced apoptosis .
3.2.3. Lysosome Pathway
Lysosomes play a critical role in multiple cellular events, for example, the degradation of biomacromolecules and the regulation of autophagy. HCMV pUL38 has been shown to prevent cell death via abrogating cellular stress responses. Sun et al. pointed out that during HCMV infection, the ferritinophagy-related protein nuclear receptor coactivator 4 (NCOA4) and lysosomal ferritin degradation are regulated by ubiquitin-specific protease 24 (USP24). pUL38 bound with and antagonized the role of USP24 and then reduced ferritinophagy, finally protecting cells against lysosomal dysfunction-induced cell death .
4. Novel Treatment Strategies for HCMV-Related Diseases
HCMV infection causes apoptosis disorder, which is involved in the initiation and progression of numerous diseases. Importantly, both positive and negative modulators of apoptosis have attracted researchers’ interest in translating these discoveries from the laboratory to clinical applications in order to improve human health . Based on the data we summarized above, regulation of apoptosis may be a novel strategy for HCMV-related disease treatment.
Leflunomide is an exciting, novel drug for cytomegalovirus infection, which significantly inhibited HCMV-infection-induced apoptosis and played an important role in the treatment of patients with HCMV infection. The study results provided a new way to fight immune dysfunction induced by HCMV infection . In contrast, Biolatti et al. demonstrated that strigolactones exert their antiviral properties by inducing the apoptosis of HCMV-infected cells . Similarly, Mo et al. revealed that treatment with chloroquine remarkably enhances the expression of cleaved caspase-3 in MCMV-infected retinal pigment epithelial cells and contributes to the apoptosis of infected cells . These studies imply that antiviral drugs resist HCMV infection by regulating apoptosis, whether promoting or inhibiting it.
Furthermore, according to the molecular mechanism of apoptosis, multiple vital proteins may be targets for the treatment of HCMV-related diseases. For instance, Zhao et al. indicated that HCMV IE86 promotes the expression of heterogeneous ribonucleoprotein A2/B1 (hnRNP A2/B1) in glioma cells and then prevents apoptosis and contributes to cell proliferation by mediating the alternative splicing of Bcl-x. Knockdown of the expression of hnRNP A2/B1 greatly weakened IE86-mediated apoptosis and cell proliferation . HCMV IE2 promoted the expression of anti-apoptotic genes, such as Mcl-1 and Bcl-2, further suppressed apoptosis, and enhanced the survival and proliferation of smooth muscle cells, which are involved in HCMV-related atherosclerosis . Thus, specifically inhibiting the expression of effector proteins of HCMV may exert positive effects during the treatment of HCMV-related diseases.
HCMV UL138 inhibited GC cell viability and induced apoptosis by reducing the expression level of Bcl-2 protein and promoting the activation of cleaved caspase-9 and caspase-3. In addition, UL138 efficiently prevented GC growth in a xenograft animal model . These findings provided a novel potential therapeutic strategy for GC treatment. More interestingly, Yang et al. pointed out that HCMV glycoprotein B plays no role in cell apoptosis and proliferation but suppresses breast cancer cell migration by downregulating the transforming growth factor (TGF)-β/Smad signaling pathway . Valle Oseguera and Spencer reported that cmvIL-10 promotes the activation of STAT3, which further inhibits apoptosis, increases proliferation, and increases the chemo-resistance of breast cancer cells . These studies revealed the significant role of cytokines in the progression of HCMV-induced breast cancer. In addition, these data may accelerate the development of novel drugs against breast cancer, such as anti-TGF-β and anti-STAT3 agents.
