| COVID-19 research v1.52 | IFNG |
Sarah Leigh changed review comment from: IFNG was identified through an OMIM search for potential viral susceptibility genes. Initial triage by Illumina (Alison Coffey and team) was given a Tier 3 grouping (experimental evidence and association data consistent with viral susceptibility). "Illumina review: From OMIM: Interferon-gamma (IFNG), or type II interferon, is a cytokine critical for innate and adaptive immunity against viral and intracellular bacterial infections and for tumor control. The importance of IFNG in the immune system stems in part from its ability to inhibit viral replication directly, but most importantly derives from its immunostimulatory and immunomodulatory effects. IFNG is produced predominantly by natural killer (NK) and natural killer T (NKT) cells as part of the innate immune response, and by CD4 (186940) and CD8 (see 186910) cytotoxic T lymphocyte (CTL) effector T cells once antigen-specific immunity develops (PMID: 178981204; Schoenborn and Wilson, 2007). From OMIM: PMID: 17215375: Huang et al. (2007) The IFNG gene SNP, -764 C>G (rs2069707) in the proximal promoter region next to the binding motif for HSF1 , was significantly associated with sustained virologic response to IFNA therapy in a cohort of hepatitis C virus-positive patients compared to a cohorts who had spontaneously cleared HCV infection or who had chronic HCV infection. Luciferase reporter and EMSA analyses showed that the -764G allele had 2- to 3-fold higher promoter activity and stronger binding affinity for HSF1 than the -764C allele. Huang et al. (2007) concluded that the -764C-G SNP is functionally important in determining viral clearance and treatment response in HCV-infected patients. From OMIM PMID: 12854077: An et al. (2003) reported an association between a SNP in the IFNG promoter region, -173 G>T, and progression to AIDS. In individuals with the rare -179T allele, but not in those with the -179G allele, IFNG is inducible by TNF. An et al. (2003) studied 298 African American HIV-1 seroconverters and found that the -179T allele was associated with accelerated progression to a CD4 cell count below 200 and to AIDS. They noted that the SNP is present in 4% of African Americans and in only 0.02% of European Americans. PMID: 26458193 Wei et al.

According to the ethnicity-based sub-group analysis, a significant difference of the IFN-γ rs2430561 T > A (IFN-γ +874T/A) polymorphism was detected associated with the increased risk of HBV infection in Asians and European-derived populations in the majority of the groups. ; to: IFNG was identified through an OMIM search for potential viral susceptibility genes.

Initial triage by Illumina (Alison Coffey and team) was given a Tier 3 grouping (experimental evidence and association data consistent with viral susceptibility). Illumina review: Receptor for the CX3C chemokine fractalkine (CX3CL1); binds to CX3CL1 and mediates both its adhesive and migratory functions. Acts as coreceptor with CD4 for HIV-1 virus envelope protein (in vitro) (PMID:9726990). Associated with rapid progression to AIDS from HIV1 infection. PMID:14607932: Garin et al. (2003) - identified two novel isoforms of the human chemokine receptor CX3CR1, produced by alternative splicing that appear to be more potent HIV coreceptors. PMID:10731151: Faure et al. (2000) - CX3CR1 is an HIV coreceptor as well as a leukocyte chemotactic/adhesion receptor for fractalkine. Faure et al. (2000) identified 2 single nucleotide polymorphisms in the CX3CR1 gene in Caucasians and demonstrated that HIV-infected patients homozygous for I249/M280 progressed to AIDS more rapidly than those with other haplotypes (relative risk = 2.13, P = 0.039). Functional CX3CR1 analysis showed that fractalkine binding is reduced among patients homozygous for this particular haplotype. Concluded that CX3CR1-I249/M280 is a recessive genetic risk factor for HIV/AIDS. PMID 28228284: Zhivaki et al. (2017) - Upregulated in RSV infection affecting severity of infection. Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract infections in infants and is characterized by pulmonary infiltration of B cells in fatal cases. Identified a population of neonatal regulatory B lymphocytes (nBreg cells) that produced interleukin 10 (IL-10) in response to RSV infection. The polyreactive B cell receptor of nBreg cells interacted with RSV protein F and induced upregulation of chemokine receptor CX3CR1. CX3CR1 interacted with RSV glycoprotein G, leading to nBreg cell infection and IL-10 production that dampened T helper 1 (Th1) cytokine production. In the respiratory tract of neonates with severe RSV-induced acute bronchiolitis, RSV-infected nBreg cell frequencies correlated with increased viral load and decreased blood memory Th1 cell frequencies. Thus, the frequency of nBreg cells is predictive of the severity of acute bronchiolitis disease and nBreg cell activity may constitute an early-life host response that favors microbial pathogenesis. PMID unavailable: Strickland et al. (2020) - Pulmonary infection with C. neoformans (opportunistic fungal pathogen and leading cause of death in HIV-affected inividuals) enhanced CX3CR1 expression in the lung. Following infection, mice lacking CX3CR1 had significantly higher pulmonary fungal burdens, as well as decreased survival times compared to wild type mice. These infected CX3CR1 knockout mice also displayed higher expression of pro-inflammatory cytokines including MIP-2, MCP-1 and CCL7, but lower expression of anti-inflammatory cytokines such as IL-10. CX3CR1 deficiency resulted in mice having dramatically enhanced neutrophil accumulation in the lungs following infection.Depletion of neutrophils drastically improved lung CFU in infected knockout mice, indicating that excessive inflammation drove fungal growth. These data indicate that CX3CR1 expression is essential for host resistance to pulmonary cryptococcal infection by inhibiting excessive lung inflammation. |

Illumina review: CCL11 is a cytokine released in response to viral infections. No evidence found of SNPs in association with SARS-CoV-2 infection. From OMIM: PMID: 14571188: Modi et al. (2003) identified 3 SNPs that formed a 31-kb haplotype (H7) spanning the CCL2-CCL7-CCL11 gene cluster on chromosome 17q. The SNPs and the H7 haplotype were significantly associated with protection from HIV-1 infection. PMID:30915442: Hoffman et al. (2019) - West Nile virus infection outcome vary among individuals with most infections resulting in asymptomatic or mild-flu like symptoms. WNV-infected females reported more symptoms than males. Males were shown to exibit a protracted cytokine response including CCL11 (and CCL2, CXCL10 and IL-15) that was absent in females. PMID:32416070: Blanco-Melo et al. (2020) - look at the transcriptional response to SARS-CoV-2 compared to other respiratory viruses. Cell and animal models of SARS-CoV-2 infection, in addition to transcriptional and serum profiling of COVID-19 patients, consistently revealed a unique and inappropriate inflammatory response. This response is defined by low levels of type I and III interferons juxtaposed to elevated chemokines and high expression of IL-6. SARS-CoV-2 shown to induce robust levels of chemokines including CCL2, CCl8 and CCL11 (Figure 4A). |

| COVID-19 research v0.349 | PVR |
Rebecca Foulger commented on gene: PVR: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): PVR, or CD155, belongs to a large family of immunoglobulin (Ig)-like molecules called nectins and nectin-like proteins, which mediate cell-cell adhesion, cell migration, and cell polarization through interaction with other nectins. It is both a viral receptor and immunomodulatory protein and is involved in many biological processes. PVR serves as the entry receptor for poliovirus and thereby is responsible for human susceptibility to poliovirus infection. Susceptibility to poliovirus is a function of the presence or absence of the cellular receptor to which the virus binds as the first step in poliovirus replication. Mendelsohn et al. (1986) succeeded in transforming a human poliovirus receptor gene into mouse L cells, which are ordinarily resistant to poliovirus infection because they do not bear a poliovirus receptor. Monoclonal antibody directed against the HeLa cell poliovirus receptor site was used in rosette assays to identify poliovirus-sensitive transformants. Evidence for PVR as a Viral Receptor, regulator of immune function and its role in cancer is described in Bowers et al (2017). CD155-deficient mice develop normally without displaying an overt phenotype. However, the animals are distinguished by distinct deficits in the development of a regular humoral immune response (Maier et al, 2007) Literature: PMID: 28870470 - Bowers et al, 2017 (Review) - PVR is an important cell adhesion protein and is involved in the transendothelial migration of leukocytes. PVR undergoes alternative splicing, generating 4 unique splice forms. Protein isoforms and interactions with Poliovirus are summarized in Table 1. In addition to its role as a receptor for the human poliovirus, several native biological functions have also been uncovered. PVR is an important cell adhesion protein and is involved in the transendothelial migration of leukocytes. Through its interactions with CD226 and TIGIT, transmembrane proteins found on leukocytes, PVR is a key regulator of the cell-mediated immune response. In this review more evidence is available for PVR as a Viral Receptor and PVR as a regulator of immune function PMID: 25113908 - Bolduan et al, 2014 - NL4-3 Vpu protein from HIV downregulates the activating NK cell receptor CD155 from the cell surface by the conserved alanine residues Ala-10, Ala-14 and Ala-18 of its TM domain to evade NK cell mediated immune response against HIV-1 infected cells (Hela cells) PMID: 19815499 - Stanietsky et al, 2009 - TIGIT (a protein expressed by all human NK cells) binds PVR and PVRL2 but not PVRL3 and inhibits NK cytotoxicity directly through its ITIM. PMID: 12943679 - Baury et al, 2003 -As the extracellular domains of the sPVR (soluble PVR) isoforms are identical to the extracellular domain of transmembrane PVR, they can compete with transmembrane PVR for the canyon-like receptor binding site of poliovirus. When sPVR is overexpressed in poliovirus susceptible HeLa cells, it significantly reduces viral entry and viral infectivity PMID: 17621371 - Maier et al, 2007 - In this study, Maier et al explore the expression profile of CD155 on murine hematopoietic cells utilizing newly generated mAb. They report on the establishment and immunological analysis of mice deficient in CD155. CD155-deficient mice (knock out) develop normally without displaying an overt phenotype. However, the animals are distinguished by distinct deficits in the development of a regular humoral immune response. Whereas systemic challenges revealed no differences, orally administered antigen evoked less efficient IgG and IgA antibody responses (Figure 7) despite of normal IgM titers when compared to wild-type mice. Therefore, CD155 may assist in an efficient humoral immune response generated within the intestinal immune system. PMID: 28800489 - Lin et al, 2017 - Amino acid changes in the C’C”D region in poliovirus receptor domain 1 disrupt poliovirus binding. We substituted this region of Pvr into the corresponding region of a murine homolog, nectin-2. The chimeric receptor, nectin-2Pvr(c'c"d), rendered transformed L cells susceptible to infection with poliovirus P1/Mahoney, but not with polioviruses P2/ Lansing and P3/Leon, due to lack of binding. PMID: 2597248 - Kanemaru et al, 2015 - Mice genetically deficient in CD155 or treated with anti-CD155 Ab exhibited attenuated Th1-type contact hypersensitivity. Thus, CD155 plays an important regulatory role in helper T cell differentiation and allergic diseases. |

| COVID-19 research v0.348 | NECTIN1 |
Rebecca Foulger commented on gene: NECTIN1: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): Amino acid substitutions in nectin-1 showed impaired entry of Herpes simplex virus (HSV) into CHO-K1 cells (PMID:1175687;12072525). Nectin-1 knockout mice inoculated with HSV in the hippocampus demonstrated that nectin-1 is necessary for neurologic disease caused by HSV (PMID:19805039). PMID 11756979 - Struyf et al. (2002) - Searched for polymorphisms in HVEM, nectin-1, and nectin-2 via sequencing in individuals shown to immune seronegative for herpes simplex virus (HSV). These individuals showed T cell responses to HSV antigens and did not have anti-HSV antibodies detected in their serum. There were three individuals that were immune seronegative, three with no signs of cellular or humoral immunity, and three with frequent reactivations of HSV who had antibody and T cell responses to HSV. One individual in the study (true seronegative as demonstrated by negative testing for HSV-1 and HSV-2 and no HSV-specific T cell immunity) was identified to have a variant in nectin-1 (c.752G>A, p.Arg199Gln) in addition to one missense variant in HVEM (table 2). This variant was screened for 644 healthy White individuals and 17 were shown to be heterozygous for the p.Arg199Gln variant and one individual had a different missense variant at the same residue. The p.Arg199Gln variant occurs in the first constant-like domain for the protein. A different domain, the N-terminal variable-like domain, has previously been shown as important for virus entry into the cell. PMID 12072525 - Martinez and Spear (2002) - Investigated whether residues 75-77 and 85 of nectin-1 (homologous to regions A and B of nectin-2) are necessary for HSV-1 entry into CHO-K1 cells (which are resistant to the entry of alphaherpesviruses unless they are created to express a gD receptor). When there were mutants involving both residues 77 and 85, there was severely diminished ability of HSV-1 or HSV-2 to enter the cell and was unable to find to soluble forms of HSV-1 and HSV-2 (table 1; fig. 3). Note that these mutants allowed entry of PRV and BHV-1. PMID 19805039 - Kopp et al. (2009) - Nectin-1 knockout (KO) mice were inoculated intracranially and into the hippocampus with herpes simplex virus (HSV) and infection of neurons compared to HVEM KO mice, HVEM/nectin-1 KO mice, and controls. Nectin-1 KO mice were resistant to disease, as were the double KO mice at doses of the virus up to 100x needed to cause disease as compared to the wildtype and HVEM KO mice (Fig. 1). Nectin-1 is necessary for neurologic disease caused by HSV. Viral antigen was not detected in brain sections from double KO mice, but could be detected for nectin-1 KO mice (limited regions), HVEM-KO mice and wildtype (more widespread) (Fig. 2A). HSV was shown to be located to the ventricular surfaces in nectin-1 KO mice and confirmed as non-parenchymal cells (Fig. 2B). |

| COVID-19 research v0.348 | MIR155 |
Rebecca Foulger commented on gene: MIR155: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): MIR155 (also referred to as BIC) is an endogenous noncoding RNA involved in regulation of the immune response, in particular T-cell differentiation, and in regulation of innate immunity (PMID: 32233818; 217121651;1746328969;20852130). This miRNA has been associated with various virus infections (PMID: 32233818;28139244;23686237;26072128). miR-155-5p expression has been shown to be induced in mice infected with influenza A virus (PMID: 32308197 - in this study, lung injury by ARDS was attenuated by deletion of miR-155, making this miRNA a potential therapeutic target in the context of COVID-19). Through single cell and bulk RNA profiling of SARS-CoV-2 and SARS-CoV infections in three human cell lines (H1299, Caco-2 and Calu-3 cells), Emanuel et al. (2020) (bioRxiv preprint doi: https://doi.org/10.1101/2020.05.05.079194) demonstrated strong expression of the immunity and inflammation-associated microRNA miRNA-155 upon viral infection with both viruses. Both viruses triggered a 16-fold upregulation of one form of miR-155 and a 3-fold upregulation of another. A role for MIR155 in viral susceptibility for a range of viruses and the immune response has also been demonstrated in a series of mouse models: PMID 23601686: In Mir155 -/- mice, Dudda et al. (2013) observed severely reduced accumulation of Cd8-positive T cells during acute and chronic viral infections with impaired control of viral replication. Lack of Mir155 led to an accumulation of Socs1 resulting in defective cytokine signaling through Stat5. Dudda et al. also concluded that MIR155 and its target, SOCS1, are key regulators of CD8-positive T cells. PMID 23275599: Lind et al. (2013) found that mice lacking Mir155 had impaired Cd8 positive T-cell responses to infections with lymphocytic choriomeningitis virus and the intracellular bacteria Listeria monocytogenes and concluded that MIR155 is required for acute CD8-positive T-cell responses and proposed that targeting MIR155 may be useful in modulating immune responses. PMID 24516198: Bhela et al. (2014) – 75 to 80% of MIR155 null mice infected ocularly with herpes simplex virus (HSV)-1 developed herpes simplex encephalitis with elevated viral titers in brain, but not in cornea. Immunohistochemical and flow cytometric analyses in Mir155-null mice showed diminished Cd8-positive T-cell numbers, functionality, and homing capacity. Adoptive transfer of HSV-1-immune Cd8-positive T cells to Mir155-null mice 24 hours after infection provided protection from HSE. The authors concluded that MIR155 deficiency results in enhanced susceptibility of the nervous system to HSV-1 infection. |

| COVID-19 research v0.348 | IFNE |
Rebecca Foulger commented on gene: IFNE: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): IFNE encodes IFNε, a type I interferon which is constitutively expressed within the epithelial cells of the female reproductive tract (FRT) and plays a role in protection against viral and bacterial infections of the FRT (Marks et al. 2019 review). Ifnε-deficient mice have increased susceptibility to infection of the FRT by Herpes Simplex Virus (HSV)-2 as well as bacterial Chlamydia muridarum(Fung et al. 2013). Ifnε activity has also been shown to reduce the infectivity of HIV through the induction of HIV restriction factors which act to inhibit different stages of the virus replication cycle (Garcia-Minambres et al. 2017; Stifter et al. 2018). PMID: 31734130: Marks et al (2019) Review - IFNE encodes IFNε, a type I interferon which is constitutively expressed within the epithelial cells of the female reproductive tract. Ifnε expression fluctuates during pregnancy and across stages of the reproductive cycle in humans and mice. Unlike other type I interferons IFNε is not regulated by PRR pathways. PMID: 23449591; Fung et al. 2013 - Ifnε-deficient mice had increased susceptibility to infection of the FRT by common sexually transmitted infections (STIs) Herpes Simplex Virus (HSV)-2 (fig 3) as measured by clinical scores of disease day 6 post infection. The Ifnε-deficient mice also showed high viral titres in the spinal cord and brain stem 7 days post infection, consistent with increase replication of the virus and/or retrograde transport of the virus. A similar susceptibility to infection by the bacterial Chlamydia muridarum was also observed (Fig 4). PMID: 28045025 Garcia-Minambres et al. (2017) - Ifnε activity was shown to impair HIV infection through induction of HIV restriction factors which act to inhibit different stages of the viral replication cycle. PMID: 29187603 Stifter et al. (2018) - Using different cell lines and reporter assays to measure interferon type I stimulation, the authors showed that recombinant murine Ifnε inhibited HIV infection in the sup-T1 cell line and in primary peripheral blood lymphocytes and furthermore induced a number of HIV restriction factors. |

| COVID-19 research v0.348 | FOLR1 |
Rebecca Foulger commented on gene: FOLR1: Evidence Summary from Illumina curation team (Alison Coffey and Julie Taylor): The FOLR1 gene encodes the folate receptor alpha (FR alpha), a glycosyl-phosphatidylinositol-linked (GPI-linked) protein that binds folic acid for transport into the cytoplasm. Chan et al. (2001) used genetic complementation to identify FR-alpha as a cofactor for cellular entry of pseudo Marburg (MBG) virus and EBO-Z pseudotype into otherwise non permissive cells. Further experiments showed FR alpha specifically binds glycoproteins of these viruses to mediate syncytia (Chan et al. 2001). PMID 11461707; Chan et al. (2001) - A complementation screen identified FR alpha as a cofactor for cellular entry of pseudo Marburg (MBG) virus into otherwise non permissive Jurkat-EctR cells (fig 1). FACs analysis showed FR alpha was present on the cell surface of other cell lines permissive for MBG infectivity (Hela cells, Vero E6, human and dog osteosarcoma cells (fig 2). FR alpha specific antagonists inhibited MBG entry (Fig 4) phospholipase C (PLC) cleaves the FR alpha receptor, cells pretreated with PLC showed decreased infectivity. When 293T cells overexpressing MBF GP were co-cultured with cells overexpressing FR alpha syncytia formation was observed, indicating that this type of membrane fusion is also mediated by FRalpha (fig 5). A similar set of experiments showed that FR alpha is also a cofactor for cellular entry of EBO-Z pseudo viruses. Yang et al. (2019) preprint: https://doi.org/10.1101/618306 - Poliovirus (PV), a prototype for human pathogenic positive-sense RNA enteroviruses, transport multiple virions en bloc via infectious extracellular vesicles secreted from host cells.

| COVID-19 research v0.347 | IDE | Alison Coffey commented on gene: IDE: Evidence Summary from Illumina curation team: Insulin-degrading enzyme (IDE), also known as insulysin, is a member of the zinc metalloproteinase family that was initially implicated in insulin degradation. It is highly conserved among different species and has the ability to interact with a variety of functionally unrelated ligands that share little homology in their primary amino acid sequences. Several human viruses use enzymes as receptors. Li et al. (2006) (PMID 17055432) established IDE as a cellular receptor for both cell-free and cell-associated Varicella-zoster virus (VZV), the cause of chickenpox and shingles in humans. VZV is likely spread as cell-free virus to susceptible hosts but transmitted by cell-to-cell spread in the body and in vitro. Li et al. (2006) showed that IDE interacts with the VZV glycoprotein E (gE) (which is essential for virus infection) through its extracellular domain. Downregulation of IDE by siRNA, or blocking of IDE with antibody, with soluble IDE protein extracted from liver, or with bacitracin inhibited VZV infection. Cell-to-cell spread of virus was also impaired by blocking IDE. Transfection of cell lines impaired for VZV infection with a plasmid expressing human IDE resulted in increased entry and enhanced infection with cell-free and cell-associated virus. Li et al. (2010) subsequently reported that a recombinant soluble IDE (rIDE) enhanced VZV infectivity at an early step of infection associated with an increase in virus internalization, and increased cell-to-cell spread. In 2017, Hahn et al. demonstrated that mature HIV-1 p6 protein (stability of which inversely affects the replication capacity of HIV-1) is a substrate for IDE. IDE is both sufficient and required for the degradation of p6, which is approximately 100-fold more efficiently degraded by IDE than its eponymous substrate insulin. An IDE specific inhibitor, 6bK, and exogenous insulin, were both shown to interfere with X4-tropic HIV-1 replication in activated PBMCs, most probably by competing with p6 for degradation by IDE. In addition, an IDE-insensitive p6 mutant of HIV-1 exhibits impaired replication capacity but is insensitive to treatment with insulin or 6bK. Conversely, neither virus release and maturation, nor the amounts of particle associated Vpr and p6 itself were altered in IDE knock out cells. The data support a model in which IDE is responsible for the rapid degradation of p6 entering the cell as part of the incoming virion, a process that appears to be crucial to achieve optimal X4-tropic virus replication. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| COVID-19 research v0.347 | IL9 | Alison Coffey commented on gene: IL9: Evidence Summary from Illumina curation team: IL9 encodes interleukin 9, which is a stimulatory cytokine that regulates inflammatory immunity (Goswami and Kaplan 2011). It has been demonstrated that high levels of IL-9 are present in nasopharyngeal aspirate of infants with disease of the respiratory tract caused by the Human respiratory syncytial virus (RSV) (Semple et al. 2007). Studies conducted on mice showed that that the severity of lung pathology correlates with IL-9 cytokine production and that Th9 cells, which produce IL-9, play an important role in the development of airway eosinophilia and bronchial hyperresponsiveness (Dodd et al. 2009; Saeki et al. 2016). IL9 polymorphisms have also been linked to sex-restricted differences in lung function, allergen sensitization, IgE levels, and the severity of respiratory syncytial virus infection (Schuurhof et al. 2010; Aschard et al. 2009). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Sarah Leigh Added comment: Comment on list classification: PMID 3208230 outlines the role of neutrophil extracellular traps (NETs) in the control of some pathogens including viruses, by virus capture and neutralization. In vivo treatment of the mice with DNase resulted in the enhanced susceptibility of IFNAR-/- mice to the CHIKV virus. Furthermore, the levels of MPO-DNA complex in acutely CHIKV-infected patients, were correlated with the levels of NETs and the viral load in the blood, suggesting that NETs are also released in natural human infection cases. Therefore, variants that result in myeloperoxidase deficiency, may well contribute to an increased susceptiblity to viral infection. At least 9 variants have been reported in Myeloperoxidase deficiency 254600 and these could well be contributing to increased viral susceptibily. |

Comments from Abdelazeem Elhabyan: GenBank - https://www.ncbi.nlm.nih.gov/gene?term=(human%5BOrganism%5D)%20AND%20TMEM173%5BGene%20Name%5D) This gene encodes a five transmembrane protein that functions as a major regulator of the innate immune response to viral and bacterial infections. The encoded protein is a pattern recognition receptor that detects cytosolic nucleic acids and transmits signals that activate type I interferon responses. Hypothesis: This gene is involved in interferon 1 pathway which is directly related to viral innate immune response. Upregulation may be associated with a protective effect or autoinflammatory response with aggravating effect. This is to be determined by clinical trials.
