Semin Arthritis Rheum 2021; 51:513-522. [PMID: 33866147 DOI: 10.1016/j.semarthrit.2021.03.004] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 01/16/2021] [Accepted: 03/03/2021] [Indexed: 02/07/2023]
Abstract
The incidence of autoimmune diseases is increasing worldwide, thus stimulating studies on their etiopathogenesis, derived from a complex interaction between genetic and environmental factors. Genetic association studies have shown the PTPN22 gene as a shared genetic risk factor with implications in multiple autoimmune disorders. By encoding a protein tyrosine phosphatase expressed by the majority of cells belonging to the innate and adaptive immune systems, the PTPN22 gene may have a fundamental role in the development of immune dysfunction. PTPN22 polymorphisms are associated with rheumatoid arthritis, type 1 diabetes, systemic lupus erythematosus, and many other autoimmune conditions. In this review, we discuss the progress in our understanding of how PTPN22 impacts autoimmunity in both humans and animal models. In addition, we highlight the pathogenic significance of the PTPN22 gene, with particular emphasis on its role in T and B cells, and its function in innate immune cells, such as monocytes, dendritic and natural killer cells. We focus particularly on the complexity of PTPN22 interplay with biological processes of the immune system. Findings highlight the importance of studying the function of disease-associated PTPN22 variants in different cell types and open new avenues of investigation with the potential to drive further insights into mechanisms of PTPN22. These new insights will reveal important clues to the molecular mechanisms of prevalent autoimmune diseases and propose new potential therapeutic targets.

Abstract
Type I interferons (IFN-I) were first discovered as an antiviral factor by Isaacs and Lindenmann in 1957, but they are now known to also modulate innate and adaptive immunity and suppress proliferation of cancer cells. While much has been revealed about IFN-I, it remains a mystery as to why there are 16 different IFN-I gene products, including IFNβ, IFNω, and 12 subtypes of IFNα. Here, we discuss shared and unique aspects of these IFN-I in the context of their evolution, expression patterns, and signaling through their shared heterodimeric receptor. We propose that rather than investigating responses to individual IFN-I, these contexts can serve as an alternative approach toward investigating roles for IFNα subtypes. Finally, we review uses of IFNα and IFNβ as therapeutic agents to suppress chronic viral infections or to treat multiple sclerosis.

Abstract
Regulatory B cells (Breg) are widely regarded as immunomodulatory cells which play an immunosuppressive role. Breg inhibits pathological autoimmune response by secreting interleukin-10 (IL-10), transforming growth factor-β (TGF-β), and adenosine and through other ways to prevent T cells and other immune cells from expanding. Recent studies have shown that different inflammatory environments induce different types of Breg cells, and these different Breg cells have different functions. For example, Br1 cells can secrete IgG4 to block autoantigens. Idiopathic membranous nephropathy (IMN) is an autoimmune disease in which the humoral immune response is dominant and the cellular immune response is impaired. However, only a handful of studies have been done on the role of Bregs in this regard. In this review, we provide a brief overview of the types and functions of Breg found in human body, as well as the abnormal pathological and immunological phenomena in IMN, and propose the hypothesis that Breg is activated in IMN patients and the proportion of Br1 can be increased. Our review aims at highlighting the correlation between Breg and IMN and proposes potential mechanisms, which can provide a new direction for the discovery of the pathogenesis of IMN, thus providing a new strategy for the prevention and early treatment of IMN.

Lack of evidence supporting a role of IFN-β and TGF-β in differential polarization of Bordetella pertussis specific-T cell responses. Cytokine 2020; 137:155313.

Abstract
Bordetella Pertussis (BP) vaccine-induced immunity is waning worldwide despite excellent vaccine coverage. Replacement of the whole-cell inactivated vaccine (wP) by an acellular subunit vaccine (aP) is thought to play a major role and to be associated with the recurrence of whooping cough. Previously, we detected that the polarization towards a Th2 and Th1/Th17 response in aP and wP vaccinees, respectively, persists upon aP boosting in adolescents and adults. Additionally, IL-9 and TGF-β were found to be up-regulated in aP-primed donors and network analysis further identified IFN-β as a potential upstream regulator of IL-17 and IL-9. Based on these findings, we hypothesized that IFN-β produced following aP vaccination may lead to increased IL-9 and decreased IL-17 production. Also, due to the well characterized role of TGF-β in both Th17 and Th9 differentiation, we put forth that TGF-β addition to BP-stimulated CD4 + T cells might modulate IL-17 and IL-9 production. To test this hypothesis, we stimulated in vitro cultures of PBMC or isolated naive CD4 + T cells from aP vs wP donors with a pool of BP epitopes and assessed the effect of IFN-β or TGF-β in proliferative responses as well as in the cytokine secretion of IL-4, IL-9, IL-17, and IFN-γ. IFN-β reduced BP-specific proliferation in PBMC as well as cytokine production but increased IL-9, IL-4, and IFN-γ cytokines in naïve CD4 + T cells. These effects were independent of the childhood vaccination received by the donors. Similarly, TGF-β reduced BP-specific proliferation in PBMC but induced proliferation in naïve CD4 + T cells. However, stimulation was associated with a generalized inhibition of cytokine production regardless of the original aP or wP vaccination received by the donors. Our study suggests that key T cell functions such as cytokine secretion are under the control of antigen stimulation and environmental cues but molecular pathways different than the ones investigated here might underlie the long-lasting differential cytokine production associated with aP- vs wP-priming in childhood vaccination.

Differential Responses by Human Respiratory Epithelial Cell Lines to Respiratory Syncytial Virus Reflect Distinct Patterns of Infection Control. J Virol 2018; 92:JVI.02202-17.

Abstract
Respiratory syncytial virus (RSV) infects small foci of respiratory epithelial cells via infected droplets. Infection induces expression of type I and III interferons (IFNs) and proinflammatory cytokines, the balance of which may restrict viral replication and affect disease severity. We explored this balance by infecting two respiratory epithelial cell lines with low doses of recombinant RSV expressing green fluorescent protein (rgRSV). A549 cells were highly permissive, whereas BEAS-2B cells restricted infection to individual cells or small foci. After infection, A549 cells expressed higher levels of IFN-β-, IFN-λ-, and NF-κB-inducible proinflammatory cytokines. In contrast, BEAS-2B cells expressed higher levels of antiviral interferon-stimulated genes, pattern recognition receptors, and other signaling intermediaries constitutively and after infection. Transcriptome analysis revealed that constitutive expression of antiviral and proinflammatory genes predicted responses by each cell line. These two cell lines provide a model for elucidating critical mediators of local control of viral infection in respiratory epithelial cells.IMPORTANCE Airway epithelium is both the primary target of and the first defense against respiratory syncytial virus (RSV). Whether RSV replicates and spreads to adjacent epithelial cells depends on the quality of their innate immune responses. A549 and BEAS-2B are alveolar and bronchial epithelial cell lines, respectively, that are often used to study RSV infection. We show that A549 cells are permissive to RSV infection and express genes characteristic of a proinflammatory response. In contrast, BEAS-2B cells restrict infection and express genes characteristic of an antiviral response associated with expression of type I and III interferons. Transcriptome analysis of constitutive gene expression revealed patterns that may predict the response of each cell line to infection. This study suggests that restrictive and permissive cell lines may provide a model for identifying critical mediators of local control of infection and stresses the importance of the constitutive antiviral state for the response to viral challenge.

Abstract
Targeted cancer immunotherapy with irradiated, granulocyte–macrophage colony-stimulating factor (GM-CSF)-secreting, allogeneic cancer cell lines has been an effective approach to reduce tumor burden in several patients. It is generally assumed that to be effective, these cell lines need to express immunogenic antigens coexpressed in patient tumor cells, and antigen-presenting cells need to take up such antigens then present them to patient T cells. We have previously reported that, in a phase I pilot study (ClinicalTrials.gov NCT00095862), a subject with stage IV breast cancer experienced substantial regression of breast, lung, and brain lesions following inoculation with clinical formulations of SV-BR-1-GM, a GM-CSF-secreting breast tumor cell line. To identify diagnostic features permitting the prospective identification of patients likely to benefit from SV-BR-1-GM, we conducted a molecular analysis of the SV-BR-1-GM cell line and of patient-derived blood, as well as a tumor specimen. Compared to normal human breast cells, SV-BR-1-GM cells overexpress genes encoding tumor-associated antigens (TAAs) such as PRAME, a cancer/testis antigen. Curiously, despite its presumptive breast epithelial origin, the cell line expresses major histocompatibility complex (MHC) class II genes (HLA-DRA, HLA-DRB3, HLA-DMA, HLA-DMB), in addition to several other factors known to play immunostimulatory roles. These factors include MHC class I components (B2M, HLA-A, HLA-B), ADA (encoding adenosine deaminase), ADGRE5 (CD97), CD58 (LFA3), CD74 (encoding invariant chain and CLIP), CD83, CXCL8 (IL8), CXCL16, HLA-F, IL6, IL18, and KITLG. Moreover, both SV-BR-1-GM cells and the responding study subject carried an HLA-DRB3*02:02 allele, raising the question of whether SV-BR-1-GM cells can directly present endogenous antigens to T cells, thereby inducing a tumor-directed immune response. In support of this, SV-BR-1-GM cells (which also carry the HLA-DRB3*01:01 allele) treated with yellow fever virus (YFV) envelope (Env) 43–59 peptides reactivated YFV-DRB3*01:01-specific CD4+ T cells. Thus, the partial HLA allele match between SV-BR-1-GM and the clinical responder might have enabled patient T lymphocytes to directly recognize SV-BR-1-GM TAAs as presented on SV-BR-1-GM MHCs. Taken together, our findings are consistent with a potentially unique mechanism of action by which SV-BR-1-GM cells can act as APCs for previously primed CD4+ T cells.

Abstract
Traditional herbal remedies stimulate and modulate the immune system, and it is thought that their glycoproteins and polysaccharides are responsible for this activity. We prepared crude water, protein, and polysaccharide extracts from Atractylodes macrocephala Koidz, Helianthus annuus L., Scutellaria barbata D. Don, and Hedyotis diffusa Willd, respectively, and compared their immune-stimulating activities in vitro and in vivo. All protein and polysaccharide samples of the plants led to greater lymphocyte proliferation and TNF-α and IL-6 production in cultured splenocytes than did the crude water extracts at the same concentrations tested. In addition, the protein and polysaccharide samples did not contain lectin- or lipopolysaccharide-like molecules, so glycoproteins were deduced to be responsible for the lymphocyte stimulation. Oral administration with each of the samples enhanced the hen egg-white lysozyme (HEL)-specific humoral immune and lymphocyte proliferative responses in HEL low-responder C57BL/6 mice. Splenocytes from the mice fed the samples showed significantly greater increases in the level of IFN-γ, but not IL-4, after stimulation with HEL compared with that from the untreated control. However, higher increases in HEL-specific IgG1, IgG2b, and IgG3 rather than IgG2a were found in the mice fed the samples. These results indicate that the sample-mediated enhancement of anti-HEL-specific humoral immune responses was due to the stimulation of B lymphocytes rather than a selective priming of helper T cell populations. Collectively, we suggest that glycoproteins and/or polysaccharides of traditional herbal remedies enhance cellular and humoral immune response induction and thus could be useful for patients who need enhanced immune function.

Abstract
Whether respiratory syncytial virus (RSV) induces severe infantile pulmonary disease may depend on viral strain and expression of types I and III interferons (IFNs). These IFNs impact disease severity by inducing expression of many anti-viral IFN-stimulated genes (ISGs). To investigate the impact of RSV strain on IFN and ISG expression, we stimulated human monocyte-derived DCs (MDDCs) with either RSV A2 or Line 19 and measured expression of types I and III IFNs and ISGs. At 24h, A2 elicited higher ISG expression than Line 19. Both strains induced MDDCs to express genes for IFN-β, IFN-α1, IFN-α8, and IFN-λ1-3, but only A2 induced IFN-α2, -α14 and -α21. We then show that IFN-α8 and IFN-α14 most potently induced MDDCs and bronchial epithelial cells (BECs) to express ISGs. Our findings demonstrate that RSV strain may impact patterns of types I and III IFN expression and the magnitude of the ISG response by DCs and BECs.

Abstract
Specific immunotherapies, including vaccines with autologous tumor cells and tumor antigen-specific monoclonal antibodies, are important treatments for PC patients. To evaluate the clinical outcomes of PC-specific immunotherapy, we performed a systematic review and meta-analysis of the relevant published clinical trials. The effects of specific immunotherapy were compared with those of nonspecific immunotherapy and the meta-analysis was executed with results regarding the overall survival (OS), immune responses data, and serum cancer markers data. The pooled analysis was performed by using the random-effects model. We found that significantly improved OS was noted for PC patients utilizing specific immunotherapy and an improved immune response was also observed. In conclusion, specific immunotherapy was superior in prolonging the survival time and enhancing immunological responses in PC patients.

Abstract
AIM To investigate the enhanced cytotoxic T lymphocyte responses against pancreatic cancer (PC) in vitro induced by dendritic cells (DCs) engineered to secrete anti-DcR3 monoclonal antibody (mAb).
METHODS DCs, T lymphocytes and primary PC cells were obtained from PC patients. DCs were transfected with a designed humanized anti-DcR3 monoclonal antibody heavy and light chain mRNA and/or total tumor RNA (DC-tumor-anti-DcR3 RNA or DC-total tumor RNA) by using electroporation technology. The identification, concentration and function of anti-DcR3 mAb secreted by DC-tumor-anti-DcR3 RNA were determined by western blotting and enzyme-linked immunosorbent assay. After co-culturing of autologous isolated PC cells with target DCs, the effects of secreting anti-DcR3 mAb on RNA-DCs’ viability and apoptosis were assessed by MTT assay and flow cytometry. Analysis of enhanced antigen-specific immune response against PC induced by anti-DcR3 mAb secreting DCs was performed using a 51Cr releasing test. T cell responses induced by RNA-loaded DCs were analyzed by measuring cytokine levels, including IFN-γ, IL-10, IL4, TNF-α and IL-12.
RESULTS The anti-DcR3 mAb secreted by DCs reacted with recombinant human DcR3 protein and generated a band with 35 kDa molecular weight. The secreting mAb was transient, peaking at 24 h and becoming undetectable after 72 h. After co-incubation with DC-tumor-anti-DcR3 RNA for designated times, the DcR3 level in the supernatant of autologous PC cells was significantly down-regulated (P < 0.05). DCs secreting anti-DcR3 mAb could improve cell viability and slow down the apoptosis of RNA-loaded DCs, compared with DC-total tumor RNA (P < 0.01). The anti-DcR3 mAb secreted by DC-tumor-anti-DcR3 RNA could enhance the induction of cytotoxic T lymphocytes (CTLs) activity toward RNA-transfected DCs, primary tumor cells, and PC cell lines, compared with CTLs stimulated by DC-total tumor RNA or control group (P < 0.05). Meanwhile, the antigen-specific CTL responses were MHC class I-restricted. The CD4+ T cells and CD8+ T cells incubated with anti-DcR3 mAb secreting DCs could produce extremely higher level IFN-γ and lower level IL4 than those incubated with DC-total tumor RNA or controls (P < 0.01).
CONCLUSION DCs engineered to secrete anti-DcR3 antibody can augment CTL responses against PC in vitro, and the immune-enhancing effects may be partly due to their capability of down-regulating DC apoptosis and adjusting the Th1/Th2 cytokine network.

Abstract
The protein tyrosine phosphatase PTPN22(C1858T) allelic polymorphism is associated with increased susceptibility for development of systemic lupus erythematosus (SLE) and other autoimmune diseases. PTPN22 (also known as LYP) and its mouse orthologue PEP play important roles in antigen and Toll-like receptor signaling in immune cell functions. We demonstrate here that PEP also plays an important inhibitory role in interferon-α receptor (IFNAR) signaling in mice. PEP co-immunoprecipitates with components of the IFNAR signaling complex. Pep(-/-) hematopoietic progenitors demonstrate increased IFNAR signaling, increased IFN-inducible gene expression, and enhanced proliferation and activation compared to Pep(+/+) progenitors in response to IFN-α. In addition, Pep(-/-) mice treated with IFN-α display a profound defect in hematopoiesis, resulting in anemia, thrombocytopenia, and neutropenia when compared to IFN-α-treated Pep(+/+) mice. As SLE patients carrying the PTPN22(C1858T) risk variant have higher serum IFN-α activity, these data provide a molecular basis for how type I IFNs and PTPN22 may cooperate to contribute to lupus-associated cytopenias.

Abstract
Dendritic cells (DCs) can be differentiated from CD14+ monocytes in the presence of interferon-α (IFNα) and granulocyte/macrophage-colony stimulating factor (GM-CSF) in vitro and are known as IFN-DCs. Circulating blood CD56+ cells expressing high levels of CD14, HLA-DR and CD86 have been shown to spontaneously differentiate into DC-like cells in vitro after their isolation from blood. We show here that IFN-DCs expressing high levels of CD56 (hereafter, CD56(high+) IFN-DCs) can be differentiated in vitro from monocytes obtained as adherent cells from healthy donors and patients with metastatic melanoma. These cells expressed high levels of CD14, HLA-DR and CD86 and possessed many pseudopodia. These CD56(high+) IFN-DCs may be an in vitro counterpart of the circulating CD56+ CD14+ CD86+ HLA-DR+ cells in blood. Conventional mature DCs differentiated from monocytes as adherent cells in the presence of GM-CSF, IL-4 and TNF-α (hereafter, mIL-4DCs) did not express CD56 or CD14. In contrast to mIL-4DCs, the CD56(high+) IFN-DCs exhibited a stronger capacity to stimulate autologous CD56+ Vγ9γδT cells highly producing IFNγ in the presence of zoledronate and IL-2. The CD56(high+) IFN-DCs possessing HLA-A*0201 effectively induced Mart-1-modified melanoma peptide (A27L)-specific CD8+ T cells through preferential expansion of CD56+ Vγ9γδT cells in the presence of A27L, zoledronate and IL-2. Vaccination with CD56(high+) IFN-DCs copulsed with tumor antigens and zoledronate may orchestrate the induction of various CD56+ immune cells possessing high effector functions, resulting in strong immunological responses against tumor cells. This study may be relevant to the design of future clinical trials of CD56(high+) IFN-DCs-based immunotherapies for patients with melanoma.

Evaluation of immuno-efficacy of a novel DNA vaccine encoding Toxoplasma gondii rhoptry protein 38 (TgROP38) against chronic toxoplasmosis in a murine model. BMC Infect Dis 2014; 14:525. [PMID: 25267356 PMCID: PMC4261603 DOI: 10.1186/1471-2334-14-525] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2014] [Accepted: 09/25/2014] [Indexed: 12/25/2022] Open
Abstract
Background Toxoplasma gondii is an obligate intracellular parasite which can infect almost all mammalian animals, leading to toxoplasmosis. T. gondii rhoptry protein 38 (TgROP38) is an active rhoptry protein kinase which is involved in the inhibitory effect on host cell transcription by down-regulating the MAPK signaling track. Methods TgROP38 gene was amplified and inserted into eukaryotic vector pVAX I and formed the DNA vaccine pVAX-ROP38. Mice in the experimental group were intramuscularly immunized with pVAX-ROP38 and those injected with pVAX I, PBS or nothing were treated as controls. After three injections at two week intervals, all mouse groups were challenged intraperitoneally with 1000 tachyzoites of the virulent T. gondii RH strain (Type I, ToxoDB #10) and 10 cysts of the PRU strain (Type II, ToxoDB #1), respectively. Results Mice inoculated with pVAX-ROP38 vaccine had a higher level of IgG antibodies (P < 0.01) and T lymphoproliferative response. The high ratio of IgG2a/IgG1 and the increasing levels of IFN-γ and IL-2 (P < 0.05) indicated an activated Th1 cell-mediated immune responses. Furthermore, the CD4+ and CD8+ proportions in vaccinated mice were also increased significantly compared with that in mice of the three control groups (P < 0.01). In the model of acute infection, the average survival time of mice in the pVAX-ROP38 group (8.1 days ± 0.75) was no statistically different compared to that in the PBS, pVAX I and blank control groups which died within 7 days. However, in the model of chronic infection, the brain cyst reduction in the pVAX-ROP38 group reached 76.6%, compared to controls (P < 0.01). Conclusions The present study revealed that the pVAX-ROP38 vaccine could elicit strong humoral and cell immunity response against chronic T. gondii infection in mice, resulting in the reduction of the brain cyst formation effectively, which suggests that TgROP38 is a desirable vaccine candidate against chronic T. gondii infection.
