Cytokines and growth factors in a biologic product obtained from patients' urine as immune-modulators to treat autoimmune and allergic diseases. Cytokine 2021; 141:155427. [PMID: 33581472 DOI: 10.1016/j.cyto.2021.155427] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 01/06/2021] [Accepted: 01/07/2021] [Indexed: 12/17/2022]
Abstract
At "Instituto de Alergias y Autoinmunidad Dr. Maximiliano Ruiz Castañeda, A.C." in Mexico City, a non-traditional health care center focused on the treatment of autoimmune and allergic diseases using personalized medicine, an alternative treatment referred to as an "immune-modulator" has been developed. In this study, we will refer to this treatment substance as the "immune-modulator." In brief, a urine sample is collected from the patient and processed to obtain the peptide fraction, which is conditioned and then administered sublingually to the patient. Sample processing involves multiple steps aimed at the removal of toxic compounds and enrichment for cytokines, growth factors, and other immune peptides that may contribute to the function of the immune-modulator. This treatment has been administered for many years, and patients testify that it is useful and reliable. Despite the benefits of this treatment, the molecular mechanisms underlying its effects have not been thoroughly investigated. Therefore, this study aims to identify immunoregulatory peptides, such as cytokines and growth factors, in the immune-modulator. Urine and immune-modulator concentrations of cytokines and growth factors were assessed using a Luminex assay. Twenty-one cytokines and growth factors were identified in immune-modulator samples. MCP-1 was identified in 100% of the samples; MIP-1β, IL-8, RANTES, INF-γ, and IP-10 were identified in approximately 65-70% of samples; IL5, IL-1B, and IL-17 in 50-60%; eotaxin, VEGF, IL-6, and FGF in about 40%; MIP-1α, IL-9, GM-CSF, G-CSF, IL-12, and IL-15 in about 20-30%; and IL-13 and PDGF-bb were identified in <6% of samples. Additionally, patients exhibited significant changes in IL-1β, IFN-γ, and MCP-1 concentrations after treatment with the immune-modulator, whereas healthy individuals showed no significant change in response to the treatment. The immune-modulator is an alternative treatment based on the administration of cytokines and growth factors obtained from the urine of patients. In this study, its composition was characterized. The isolated products could be responsible for the effects of the immune-modulator. Further trials are required to evaluate the effective delivery of these molecules by the administration route described.

Heterogeneity of the cytokinome in undifferentiated arthritis progressing to rheumatoid arthritis and its change in the course of therapy. Move toward personalized medicine. Cytokine 2017; 97:1-13. [PMID: 28551592 DOI: 10.1016/j.cyto.2017.05.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Revised: 05/12/2017] [Accepted: 05/13/2017] [Indexed: 12/26/2022]
Abstract
OBJECTIVES To conduct a comprehensive analysis of cytokine concentrations in sera and mononuclear cell supernatants in order to examine inter- and intra-individual cytokine variations in undifferentiated arthritis progressing to rheumatoid arthritis and healthy control groups. METHODS Patients with UA (undifferentiated arthritis) developing RA (rheumatoid arthritis) (UA→RA) (n=16) and healthy controls (n=16) were enrolled into the study. UA→RA patients were followed up for six months since the final RA diagnosis. Cytokines IFN-γ, IL-10, TNF, IL-17A, IL-6, IL-1β, IL-2 in sera and mononuclear cell supernatants in 72h and 120h culture variants with- and without anti-CD3 stimulations were assayed using flow cytometric bead array. RESULTS The cytokine profile of UA→RA differs from the healthy individual cytokine profile. It is possible to observe specific cytokine pattern characterizing each patient, which alters during course of disease. Specifically, we can distinguish three UA→RA cohorts: the group of patients susceptible to the therapy, characterized by the drop of cytokine levels between 1st and 3rd visit with visible decrease of cytokines in 2nd visit and then secondary slighter increase in 3rd visit; the group of patients refractory or clinically worsening on the therapy, characterized by the highest cytokine levels at 2nd visit with secondary decrease in 3rd visit; and the group of patients with variable responses to the therapy without any specific common cytokine pattern. The cytokine patterns in supernatants of PBMC stimulated anti-CD3 for 72h and 120h are very similar. CONCLUSIONS The personal profile including multiplexed cytokine patterns in serum and supernatant may be potentially used for optimization of therapy introduction and monitoring.

Abstract
Lipopolysaccharide (LPS) plays an important role in bone resorption, which involves numerous cytokines through various signaling pathways. RANKL and interleukin (IL)-6 are two important cytokines that are involved in bone remodeling. The aim of this study was to evaluate the effect of LPS on RANKL and IL-6 gene expression, the relationship of RANKL and IL-6, and the role of extracellular signal-regulated kinases 1/2 (ERK1/2) on IL-6 secretion induced by LPS in MLO-Y4 cells. The cells were stimulated by LPS at different concentrations (1, 10, 100, 500, and 1000 ng/mL) for different durations (0.5, 1, 2, 4, and 8 h and 0.5, 1, 1.5, 2, and 4 h), and the mRNA expressions of RANKL and IL-6 were determined by PCR. In the presence of 100 ng/mL LPS at different time points (0.5, 1, 1.5, 2, and 4 h), IL-6 secretion and ERK1/2 phosphorylation in the cells were determined by ELISA and western blotting, respectively. STAT3 phosphorylation in cells simulated by 100 ng/mL LPS at different time points (0.5, 1, 2, 4, and 8 h) was assessed by western blotting. We found that LPS significantly up-regulated RANKL expression and activated the ERK1/2 pathway to induce IL-6 mRNA expression and protein synthesis in MLO-Y4 cells. However, the increased IL-6 was blocked by pre-treatment of MLO-Y4 cells with the ERK1/2 inhibitor U0126 (10 µM), and the enhanced RANKL was blocked by the STAT3 inhibitor S3I-201 (100 µM). Our results indicate that LPS up-regulates osteocyte expression of RANKL and IL-6, and the increased RANKL is associated with the up-regulation of IL-6, which involves the ERK1/2 pathway.

Abstract
Decoy receptor 3 (DcR3) competitively binds to three ligands, Fas ligand, lymphotoxin‑related inducible ligand that competes for glycoprotein D binding to herpesvirus entry mediator on T cells and tumor necrosis factor‑like ligand 1A (TL1A), to prevent their effects. Recent studies have suggested that DcR3 directly affects cells as a ligand. Using a microarray assay, our group newly identified interleukin (IL)‑12B, which encodes the p40 subunit common to IL‑12 and IL‑23, as one of the genes for which expression in fibroblast‑like synoviocytes from patients with rheumatoid arthritis (RA‑FLS) is induced by DcR3. The present study demonstrated that IL‑12B mRNA expression was upregulated by DcR3‑Fc in RA‑FLS in a dose‑dependent manner, but not in OA‑FLS. IL‑12B p40 protein in RA‑FLS was increased when stimulated with DcR3‑Fc. Pre‑treatment with anti‑TL1A antibody suppressed the upregulation of IL‑12B mRNA in RA‑FLS stimulated with DcR3‑Fc. DcR3 mRNA expression in RA‑FLS was induced by IL‑23, but not by IL‑12. These results indicated that DcR3 may increase IL‑12 or IL‑23 by inducing IL‑12B p40 expression via membrane‑bound TL1A on RA‑FLS and that IL‑23 reciprocally induces DcR3 expression in RA‑FLS. DcR3 and IL‑23 may interact in a feedback loop that aggravates local inflammation in patients with RA.

Abstract
Several observations suggest endogenous suppressors of inflammatory mediators are present in human blood. alpha-1-Antitrypsin (AAT) is the most abundant serine protease inhibitor in blood, and AAT possesses anti-inflammatory activity in vitro and in vivo. Here, we show that in vitro stimulation of whole blood from persons with a genetic AAT deficiency resulted in enhanced cytokine production compared with blood from healthy subjects. Using whole blood from healthy subjects, dilution of blood with RPMI tissue-culture medium, followed by incubation for 18 h, increased spontaneous production of IL-8, TNF-alpha, IL-1 beta, and IL-1R antagonist (IL-1Ra) significantly, compared with undiluted blood. Dilution-induced cytokine production suggested the presence of one or more circulating inhibitors of cytokine synthesis present in blood. Serially diluting blood with tissue-culture medium in the presence of cytokine stimulation with heat-killed Staphylococcus epidermidis (S. epi) resulted in 1.2- to 55-fold increases in cytokine production compared with S. epi stimulation alone. Diluting blood with autologous plasma did not increase the production of IL-8, TNF-alpha, IL-1 beta, or IL-1Ra, suggesting that the endogenous, inhibitory activity of blood resided in plasma. In whole blood, diluted and stimulated with S. epi, exogenous AAT inhibited IL-8, IL-6, TNF-alpha, and IL-1 beta significantly but did not suppress induction of the anti-inflammatory cytokines IL-1Ra and IL-10. These ex vivo and in vitro observations suggest that endogenous AAT in blood contributes to the suppression of proinflammatory cytokine synthesis.

Abstract
Adacolumn selective granulocyte and monocyte apheresis (GMA) depletes activated leukocytes in patients with ulcerative colitis (UC). However, this per se cannot fully explain the efficacy of GMA. We have investigated the effects of GMA on the expression of toll-like receptors (TLRs) and plasma interleukin-8 (IL-8). Twenty-two patients with clinical activity index (CAI) of 5-17, 15 with total colitis and 7 with left-sided colitis, were included. Each patient could receive up to 10 GMA sessions, at 1 or 2 sessions per week. GMA was added to the patients' ongoing medication following a relapse or worsening UC, but no additional medication was given. Further, at entry and pre-GMA, blood samples were taken for full blood cell count, expression of TLRs on leukocytes, and plasma IL-8. Seventy-five percent of patients achieved remission after the 10th session (CAI, < or =4; P < 0.005) and there was a marked fall in C-reactive protein (P < 0.01), plasma IL-8 (P < 0.001), and granulocytes (P < 0.05) but an increase in lymphocytes (P < 0.05). The expression of TLR2 on granulocytes was down-modulated (P < 0.05) together with suppression of inflammatory cytokines produced by peripheral blood leukocytes. In conclusion, GMA appears to be an effective adjunct therapy to induce remission in the majority of patients, who are then spared from excess drug therapy. The procedure is associated with sustained immunomodulation. Control studies should strengthen these findings.

Abstract
Stimulation of monocytes/macrophages after cell contact with preactivated T cells has been suggested to contribute to the excessive TNF-α production in rheumatoid arthritis (RA). In this study, T cell-contact-dependent TNF-α production by peripheral-blood monocytes in vitro was investigated and found to be significantly lower in treated and untreated patients with RA than in healthy controls. This suppression was not due to a general deficiency of monocytes to respond, because responses to lipopolysaccharide were comparable in patients and controls. In agreement with the pivotal role of TNF-α in RA, T cell-dependent induction of TNF-α in synovial macrophages was fivefold to tenfold higher than in peripheral-blood monocytes from either patients or controls. The decreased response of peripheral-blood monocytes from patients with RA was found to be mediated by inhibitory serum factors, because the addition of patient sera to monocytes from healthy controls suppressed TNF-α response in the co-culture assay. Preincubation of monocytes from healthy controls with RA serum was sufficient to suppress the subsequent TNF-α response in T cell co-cultures, indicating that inhibitory factors do indeed bind to monocyte surfaces, which might represent a regulatory counter-action of the immune system to the long-standing and consuming autoimmune process in RA. There are some indications that apolipoprotein A-1 might be part of this regulatory system.

Abstract
Regulatory T cells have been clearly implicated in the control of disease in murine models of autoimmunity. The paucity of data regarding the role of these lymphocytes in human autoimmune disease has prompted us to examine their function in patients with rheumatoid arthritis (RA). Regulatory (CD4+CD25+) T cells isolated from patients with active RA displayed an anergic phenotype upon stimulation with anti-CD3 and anti-CD28 antibodies, and suppressed the proliferation of effector T cells in vitro. However, they were unable to suppress proinflammatory cytokine secretion from activated T cells and monocytes, or to convey a suppressive phenotype to effector CD4+CD25− T cells. Treatment with antitumor necrosis factor α (TNFα; Infliximab) restored the capacity of regulatory T cells to inhibit cytokine production and to convey a suppressive phenotype to “conventional” T cells. Furthermore, anti-TNFα treatment led to a significant rise in the number of peripheral blood regulatory T cells in RA patients responding to this treatment, which correlated with a reduction in C reactive protein. These data are the first to demonstrate that regulatory T cells are functionally compromised in RA, and indicate that modulation of regulatory T cells by anti-TNFα therapy may be a further mechanism by which this disease is ameliorated.

Abstract
OBJECTIVES It has been suggested that periodontal inflammation may result in an altered immune response. The peripheral immune capacity in periodontitis patients can be investigated using lipopolysaccharide (LPS)-stimulated whole blood cell cultures (WBCC), known to reflect the behavior of monocytes in particular. A previous study in our laboratory revealed that monocytes in the stimulated cultures from periodontitis patients behaved functionally different compared with controls. The present study investigated whether this different response of periodontitis patients' monocytes is intrinsic or acquired. MATERIAL AND METHODS The release of inflammatory mediators was measured in Escherichia coli LPS-stimulated WBCC from 12 periodontitis patients before and after periodontal therapy. In addition, the total leukocyte and leukocyte differentiation counts were also determined in the patients before and after therapy. RESULTS The levels of interleukin (IL)-12p70 in cell culture supernatants increased two times and those of prostaglandin E2 showed a trend towards reduction after therapy, whereas the levels of IL-1beta, IL-6, IL-8, IL-10, IL-12p40 and tumor necrosis factor-alpha did not change. The total number of white blood cells was decreased after periodontal therapy. CONCLUSIONS After periodontal therapy, the functional phenotype of the peripheral blood monocytes from patients was reconstituted, resembling that of subjects without periodontitis.

Abstract
BACKGROUND As some residual inflammation may remain after periodontal therapy, the present pilot study investigated the long-term effect of full-mouth tooth extraction therapy on the responsiveness of peripheral blood monocytes in a case with generalized terminal adult periodontitis. METHODS Before and 3, 9, 20 and 32 months after therapy, venous blood was collected. Total and differential white blood cell counts were determined and whole blood cell cultures (WBCC) were incubated with lipopolysaccharide (LPS) to stimulate the production of inflammatory mediators by monocytes. RESULTS After full-mouth tooth extraction, the numbers of total peripheral white blood cells and neutrophils decreased over time. The release of the chemokines interleukin (IL)-8 and macrophage chemoattractant protein (MCP)-1 in the cultures decreased twofold over time, whereas no changes were seen for the other studied cytokines, chemokines and prostaglandin E2. CONCLUSION On the basis of previous studies and the present case, the high production of IL-8 and MCP-1 by monocytes in LPS-stimulated WBCC from periodontitis patients is most likely acquired, as their levels decrease over time when the periodontal infection is controlled. The possible connection between periodontitis and atherosclerosis through IL-8 and MCP-1 is discussed.

Abstract
Endotoxin (lipopolysaccharide, LPS) inducible cytokine release by human whole blood is increasingly used to model inflammatory responses in vitro, to detect the presence of pyrogenic contaminations as well as to monitor disease states or immunomodulatory treatments ex vivo. However, the LPS-stimulated blood model primarily allows the assessment of monocyte responses. Here, a whole blood model was established which allows assessment of lymphocyte responses. Four different superantigens, namely staphylococcal enterotoxin A and B (SEA, SEB), toxic shock syndrome toxin-1 (TSST-1) or streptococcal exotoxin A (SPEA) were tested with respect to the induction of lymphokine release. All superantigens were capable of inducing significant amounts of the lymphokines interferon-gamma (IFNgamma), interleukin 2 (IL-2), IL-4, IL-5, IL-13 and tumor necrosis factor beta (TNFbeta) after 72 h of incubation. Concentration-dependencies and kinetics were determined. Blood from 160 healthy donors was used to assess the variability of SEB-inducible lymphokine release. Interindividual differences were more pronounced compared to LPS-inducible monokine release. However, the individual response was maintained when blood from six donors was tested once a week for 8 weeks, suggesting that the individual response represents a donor characteristic. The model appears to be suitable for the evaluation of immunomodulatory agents in vitro as well as ex vivo.

Abstract
Bacteria colonizing tooth surfaces are essential in the induction of an inflammatory response in the periodontal tissues, but do not cause periodontitis in everyone, implicating differences in the host immune response. These possible differences were studied using lipopolysaccharide (LPS)-stimulated whole blood cell cultures (WBCC), which revealed a down regulation of monocyte derived interleukin-12 (IL-12p70) in untreated periodontitis patients and an up regulation after therapy. IL-12p70 is a crucial factor in the differentiation of Th1 cell responses. Since CC chemokines are able to influence the T cell differentiation via cytokine secretion in antigen-presenting cells, the production of CC chemokines in periodontitis was evaluated. Therefore WBCC were stimulated with LPS from Escherichia coli for 18 h and the levels of IL-12p70 and CC chemokines were measured in the supernatants by ELISA. Untreated periodontitis patients released 2 fold more RANTES (regulated on activation normal T cell expressed and secreted) (P = 0.01) and lower levels of IL-12p70 in comparison to controls (P < 0.05). A trend towards higher levels of macrophage chemoattractant protein-1 (MCP-1) (P = 0.07) was also seen in untreated periodontitis patients; while similar levels of monocyte derived chemokine (MDC) and macrophage inflammatory proteins-1 alpha and -1 beta (MIP-1 alpha and -1 beta) were found. After periodontal therapy no changes were seen with regard to MDC, MIP-1 alpha, MIP-1 beta and RANTES, whereas the MCP-1 levels decreased (P < 0.05) and the IL-12p70 levels strongly increased (P < 0.01). The data showed a consistent inverse correlation between the levels of MCP-1 and IL-12p70, and their proportional changes after therapy correlated with the clinical inflammatory response after therapy. This indicates that the disease state regulates the release of IL-12p70 and MCP-1 in E. coli LPS-stimulated WBCC. In contrast, the persistent augmented levels of RANTES after therapy are suggestive for an intrinsic behaviour.

Abstract
OBJECTIVE To determine whether measurements of different autoantibodies (Ab) and cytokines are useful to distinguish very early rheumatoid arthritis (RA) from other inflammatory rheumatisms. METHODS From a population-based recruitment, 32 patients with very early polyarthritis (median duration: 4 months) were studied. Evaluations at entry (M0), and at 6 (M6) and 12 months (M12). Ab tested: rheumatoid factors (RF) by agglutination methods and ELISA, antiperinuclear factor (APF), antikeratin Ab (AKA), anti-Sa and antinuclear Ab. Cytokine production (TNFalpha, IL2, IFNgamma, IL1beta, IL10) in whole blood cell culture (WBCC) was determined at M0. At M12, patients were classified as having RA (N = 15) or other rheumatic diseases. RESULTS At M0, AKA/APF and anti-Sa Ab frequencies were low, 13% and 7%, respectively. While most Ab detected at M0 persisted, others appeared during follow-up, particularly APF, which rose from 13 to 40% at M12. At M6, IgM-RF was detected in two RA patients exclusively by ELISA. AKA/APF were found to be highly specific markers for RA (100% specificity). At some time during follow-up, two RF-negative RA patients were AKA-positive. In two patients, AKA and APF were present at M0 before they satisfied ACR criteria. IL2 and IFNgamma production was significantly lower (P < 0.05) for RA patients. CONCLUSION AKA/APF and anti-Sa Ab were detected in community cases of very early RA. AKA/APF and RF detected by ELISA might contribute to an earlier diagnosis of RA. Low production of IFNgamma and IL2 in WBCC constituted a distinct immunopathological feature in very early RA patients.

Abstract
We previously isolated a rheumatoid arthritis-related antigen (RA-A47) protein that had reactivity with RA sera from a human chondrosarcoma-derived chondrocytic cell line, HCS-2/8. Sequencing analysis of ra-a47 cDNA revealed RA-A47 as a product of the colligin-2 gene, which is also known as the human heat shock protein (HSP) 47 gene. Expression of hsp47 has been shown to be cooperatively altered with that of collagen genes upon stimulation. In this study, it was confirmed that the mRNA expression of ra-a47 and COL2A1, a type II collagen gene, was upregulated on stimulation with transforming growth factor (TGF) beta in chondrocytes. However, in contrast, inflammatory cytokines such as tumor necrosis factor (TNF) alpha, interferon (IFN) beta, and interleukin (IL)-6 downregulated the expression of ra-a47 mRNA, whereas the expression of COL2A1 mRNA was not repressed, or even upregulated, in HCS-2/8 cells. Of note, inducible NO synthase (iNOS) and matrix metalloproteinase (MMP)-9 mRNAs were strongly stimulated by TNFalpha. We also found that cell-surface type II collagen disappeared upon such a stimulation, suggesting that decrement of RA-A47 may inhibit the secretion of type II collagen and lead to its accumulation inside the cells. RA-A47 was detected in the cultured medium of TNFalpha-treated HCS-2/8 cells and of IL-1-treated rabbit chondrocytes by Western blot analysis. Under the same conditions, RA-A47 was detected on the cell surface by immunofluorescence staining. These findings demonstrate that the RA-A47 chaperone protein is specifically downregulated, causing the intracellular accumulation of unsecretable type II collagen, while the extracellular matrix (ECM) is degraded by MMPs and iNOS through the stimulation of chondrocytes by TNFalpha. The altered localization of RA-A47 to the surface or outside of cells may represent the mechanism for the recognition of RA-A47 as an autoantigen during rheumatoid arthritis.

Abstract
Currently, few informations are available about spontaneous production of T cell cytokines in rheumatoid arthritis (RA) peripheral blood (PB), because these cytokines are generally under the detection threshold of ELISAs. Because the Th1/Th2 balance could help to determine the outcome of RA, we used a sensitive and quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) method to mesure spontaneous T cell production of IL-2, IL-4, IL-10, and IFN-gamma mRNAs using unstimulated PBMC from 25 active RA patients, not taking any DMARDs for at least 6 weeks, and 19 healthy controls. Spontaneous IL-2 and IL-4 mRNA expressions are significantly lower in RA patients compared to healthy controls. Levels of IL-10 and IFN-gamma are similar in the two groups. No correlation was found between cytokine mRNA levels and clinical parameters. Spontaneous IL-4 and IL-10 mRNA levels are respectively correlated to the number of CD4+ T cells and to the number of monocytes in PB. After in vitro stimulation, IFN-gamma mRNA production by RA PBMC is significantly decreased. Most of the patients cannot be classified as having a T cell cytokine type 1 or type 2 secretion pattern in PB. IL-2 and IL-4 mRNAs in PB of active RA are produced at a low spontaneous level and the response to in vitro activation by mitogen is weak.

Abstract
Interferon-gamma (IFN-gamma) plays a crucial role in the regulation of the immune response. Alterations in IFN-gamma production have been found in several diseases including multiple sclerosis (MS). Such alterations could be caused by the action of different factors on cytokine production, or, theoretically, by mutations in the gene. We screened the IFN-gamma gene promoter and part of the first intron, known to contain a c-Rel specific enhancer, for possible mutations by sequencing. We found a C to T substitution in the IFN-gamma promoter at position -333. Screening for this mutation by sequence-specific PCR in 214 MS patients and 164 controls identified two patients, both heterozygous, but no controls with this mutation. No mutations were found in the first intron. The interferon-gamma gene is highly conserved and changes in IFN-gamma expression are probably due to the influence of regulatory factors on gene transcription, rather than gene polymorphisms.
