Abstract
Purpose: There is a paucity of evidence on the impact of immune-mediated inflammatory disease (IMID) treatments on the immunogenicity of SARS-CoV-2 vaccination. The purpose of this literature review is to address the question of whether patients with IMIDs receiving secukinumab, a fully human anti-interleukin-17A monoclonal antibody, have an adequate immune response after SARS-CoV-2 vaccination. Materials and Methods: Clinical studies that evaluated the effect of secukinumab on immune responses in patients with IMIDs after SARS-CoV-2 vaccination were searched in publication databases, including Medline and Embase, until May 2022. Results: From the 53 articles identified, a total of 11 articles were included. Overall, the majority of the patients treated with secukinumab elicited an adequate immune response to SARS-CoV-2 vaccines. Patients receiving secukinumab for IMIDs developed cellular immune responses following vaccination with the BNT162b2 vaccine, and there were no significant differences in the overall humoral and cellular immune responses between patients and healthy individuals. The third dose of the BNT162b2 mRNA vaccine resulted in a positive antibody response in secukinumab-treated patients. Conclusion: The available data provide no evidence of impairment in immunological response to SARS-CoV-2 vaccines by secukinumab in patients with IMIDs.

Etiology, clinical characteristics, and risk factors associated with severe influenza-like illnesses in Mexican adults. IJID REGIONS 2023; 6:152-158. [PMID: 36865993 PMCID: PMC9972394 DOI: 10.1016/j.ijregi.2023.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 01/20/2023] [Accepted: 01/23/2023] [Indexed: 02/04/2023]
Abstract
Objective The aim of this study was to determine the risk factors associated with severe influenza-like illness (ILI) in Mexican adults that could be useful to clinicians when assessing patients with ILI. Methods Data from adult patients enrolled from 2010 through 2014 in ILI002 - a prospective hospital-based observational cohort study - were analyzed. Etiology and clinical characteristics were compared between cases of severe ILI (defined as hospitalization and/or death) and cases of non-severe ILI. Results Overall, 1428 (39.0%) out of a total 3664 cases of ILI were classified as severe. Adjusted analyses showed a higher risk of severe ILI associated with signs and symptoms related to lower tract infection, i.e. cough with sputum (odds ratio (OR) 2.037, 95% confidence interval (CI) 1.206-3.477; P = 0.008), dyspnea (OR 5.044, 95% CI 2.99-8.631; and shortness of breath (OR 5.24, 95% CI 3.0839.124; P < 0.001), and with increases in lactate dehydrogenase (OR 4.426, 95% CI 2.321-8.881; P < 0.001) and C-reactive protein (OR 3.618, 95% CI 2.5955.196; P < 0.001). Further, there was an increased risk of severe ILI with a longer time between symptom onset and inclusion (OR 1.108, 95% CI 1.049-1.172; P < 0.001) and with chronic steroid use (OR 14.324, 95% CI 8.059-26.216; P < 0.001). Conclusions Respiratory viruses can cause severe ILI. The results of this study highlight the importance of evaluating data compatible with lower tract involvement and previous use of immunosuppressants at baseline, because patients meeting these conditions may develop severe illness.

Abstract
Immune dysregulation is a risk factor for several diseases, including infectious diseases. Immunostimulatory agents have been used for the treatment of immune dysregulation, but deleterious adverse effects have been reported. The present study aims to establish the anti-oxidant and immunity-enhancing effects of Sambu-Tang (SBT), composed of Panax ginseng and Aconitum carmichaeli, and stigmasterol (Stig), an active compound of SBT. Immune-related factors were analyzed in RAW264.7 macrophage cells, mouse primary splenocytes, and the serum and spleen of cyclophosphamide-induced immunosuppressed mice. Results showed that the production levels of nitric oxide (NO) and expression levels of inducible NO synthase and heme oxygenase-1 were increased following SBT or Stig treatment in RAW264.7 cells. SBT or Stig increased the production levels of G-CSF, IFN-γ, IL-12, IL-2, IL-6, and TNF-α and induced the activation of NF-κB in RAW264.7 cells. SBT or Stig promoted splenic lymphocyte proliferation and increased splenic NK cell cytotoxic activity. In addition, SBT or Stig enhanced the levels of IFN-γ, IL-12, IL-2, IL-6, or TNF-α in the serum and spleen of the immunosuppressed mice. SBT or Stig increased the superoxide dismutase activity in the spleen. Collectively, SBT and Stig possess anti-oxidant and immunomodulatory activities, so they may be considered effective natural compounds for the treatment of various symptoms caused by immune dysregulation.

Abstract
Induction of immune tolerance for solid organ and vascular composite allografts is the Holy Grail for transplantation medicine. This would obviate the need for life-long immunosuppression which is associated with serious adverse outcomes, such as infections, cancers, and renal failure. Currently the most promising means of tolerance induction is through establishing a mixed chimeric state by transplantation of donor hematopoietic stem cells; however, with the exception of living donor renal transplantation, the mixed chimerism approach has not achieved durable immune tolerance on a large scale in preclinical or clinical trials with other solid organs or vascular composite allotransplants (VCA). Ossium Health has established a bank of cryopreserved bone marrow (BM), termed "hematopoietic progenitor cell (HPC), Marrow," recovered from deceased organ donor vertebral bodies. This new source for hematopoietic cell transplant will be a valuable resource for treating hematological malignancies as well as for inducing transplant tolerance. In addition, we have discovered and developed a large source of mesenchymal stem (stromal) cells (MSC) tightly associated with the vertebral body bone fragment byproduct of the HPC, Marrow recovery process. Thus, these vertebral bone adherent MSC (vBA-MSC) are matched to the banked BM obtained from each donor, as opposed to third-party MSC, which enhances safety and potentially efficacy. Isolation and characterization of vBA-MSC from over 30 donors has demonstrated that the cells are no different than traditional BM-MSC; however, their abundance is >1,000-fold higher than obtainable from living donor BM aspirates. Based on our own unpublished data as well as reports published by others, MSC facilitate chimerism, especially at limiting hematopoietic stem and progenitor cell (HSPC) numbers and increase safety by controlling and/or preventing graft-vs.-host-disease (GvHD). Thus, vBA-MSC have the potential to facilitate mixed chimerism, promote complementary peripheral immunomodulatory functions and increase safety of BM infusions. Both HPC, Marrow and vBA-MSC have potential use in current VCA and solid organ transplant (SOT) tolerance clinical protocols that are amenable to "delayed tolerance." Current trials with HPC, Marrow are planned with subsequent phases to include vBA-MSC for tolerance of both VCA and SOT.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic is concerning for patients with neuroimmunological diseases who are receiving immunotherapy. Uncertainty remains about whether immunotherapies increase the risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or increase the risk of severe disease and death upon infection. National and international societies have developed guidelines and statements, but consensus does not exist in several areas. In this Review, we attempt to clarify where consensus exists and where uncertainty remains to inform management approaches based on the first principles of neuroimmunology. We identified key questions that have been addressed in the literature and collated the recommendations to generate a consensus calculation in a Delphi-like approach to summarize the information. We summarize the international recommendations, discuss them in light of the first available data from patients with COVID-19 receiving immunotherapy and provide an overview of management approaches in the COVID-19 era. We stress the principles of medicine in general and neuroimmunology in particular because, although the risk of viral infection has become more relevant, most of the considerations apply to the general management of neurological immunotherapy. We also give special consideration to immunosuppressive treatment and cell-depleting therapies that might increase susceptibility to SARS-CoV-2 infection but reduce the risk of severe COVID-19.

Abstract
Cytosolic acetyl-CoA is an intermediate of the synthesis of most secondary metabolites and the source of acetyl for protein acetylation. The formation of cytosolic acetyl-CoA from citrate is catalysed by ATP-citrate lyase (ACL). However, the function of ACL in global metabolite synthesis and global protein acetylation is not well known. Here, four genes, PaACLA1, PaACLA2, PaACLB1, and PaACLB2, which encode the ACLA and ACLB subunits of ACL in Petunia axillaris, were identified as the same sequences in Petunia hybrida 'Ultra'. Silencing of PaACLA1-A2 and PaACLB1-B2 led to abnormal leaf and flower development, reduced total anthocyanin content, and accelerated flower senescence in petunia 'Ultra'. Metabolome and acetylome analysis revealed that PaACLB1-B2 silencing increased the content of many downstream metabolites of acetyl-CoA metabolism and the levels of acetylation of many proteins in petunia corollas. Mechanistically, the metabolic stress induced by reduction of acetyl-CoA in PaACL-silenced petunia corollas caused global and specific changes in the transcriptome, the proteome, and the acetylome, with the effect of maintaining metabolic homeostasis. In addition, the global proteome and acetylome were negatively correlated under acetyl-CoA deficiency. Together, our results suggest that ACL acts as an important metabolic regulator that maintains metabolic homeostasis by promoting changes in the transcriptome, proteome. and acetylome.

Abstract
The Hippo-Yes-associated protein (YAP)/transcriptional co-activator with PDZ-binding motif (TAZ), originally identified as a regulator of tissue generation and tumorigenesis, has been proven to have a pivotal position in immunity. Its multi-faceted roles in regulating immunity cover both intrinsic mechanism of immune cells and the crosstalk with non-immune cells. Survival of the allogeneic embryo in the maternal uterine environment depends on immune tolerance, supported by the highly orchestrated cooperation between decidual immune cells, decidual stromal cells and trophoblasts at the maternal-fetal interface. The abnormal maternal-fetal dialogue is believed to be associated with adverse pregnancy outcomes such as spontaneous pregnancy loss. Recent breakthroughs shed light on the how the Hippo-YAP/TAZ manipulate the decidualization and trophoblast invasion, while further research is needed to integrate and reconcile existing findings of the Hippo-YAP/TAZ in immunity and to extend them at the context of pregnancy. In this review, we summarized the Hippo-YAP/TAZ pathways, detailed the effects of YAP/TAZ on immune cells, and discussed the role of YAP/TAZ at the maternal-fetal interface and the potential of YAP/TAZ on immunity regulation at the context of pregnancy. Given the remarkable effect of therapeutic intervention of YAP/TAZ in cancer and autoimmune diseases, it is worthy to explore the response to YAP/TAZ inhibition in the maternal-fetal immunity. This may provide a new valuable target for therapy of pregnancy loss, or potentially other pregnancy complications.

Abstract
Phellinus species is a mushroom used as traditional medicine in Eastern Asia. Research on Phellinus baumii (PB) is relatively limited; however, it has been reported to have antioxidant, DNA damage-protecting, immunostimulating, and antidiabetic activities. In our previous study on anti-inflammatory properties in lipopolysaccharide-stimulated RAW 264.7 cells and the various bioactive components of PB, we propose that PB could exert immune enhancing effects. Therefore, our current study aimed to investigate the immune-enhancing effect on immunosuppressed mice. Different concentrations of PB extract (0, 50, 100, 200, and 400 mg/kg body weight) were given to mice via oral gavage for 6 weeks accompanied by intraperitoneal cyclophosphamide administration to induce immunosuppression. A bone marrow micronucleus test was performed in mice to screen for potential genotoxic compounds. Splenocyte viability and proliferation, splenic and peritoneal natural killer cell activities, and hematological markers were then measured. Cytokines in the spleen and serum, as well as splenic mRNA levels of nuclear factor-κB; interferon-γ; tumor necrosis factor-α; and interleukin (IL)-1β, IL-6, and IL-12, were determined in mice. As a result, PB ameliorated T- and B-lymphocyte proliferation, splenic and peritoneal NK cell activities, bone marrow cells, hematological markers, cytokine levels, and T-lymphocyte numbers. Moreover, serum and spleen cytokine levels and mRNA expression were elevated in the PB groups compared to controls. Our results suggest that the PB extract can be used as a potent immunomodulator under immunosuppressive conditions. Thus, PB may be used as a potent biofunctional and pharmaceutical material to potentially enhance human immunity.

Other immunomodulatory agent-related lymphoproliferative diseases: a single-center series of 72 biopsy-confirmed cases. Mod Pathol 2018; 31:1457-1469.

Abstract
Ongoing development of new drugs, as well as novel indications in the treatment of autoimmune diseases leads to the increasing use of immunomodulatory and immunosuppressive drugs. Immunomodulatory agent-related lymphoproliferative disorders are a known and potentially life threatening complication of chronic administration of these drugs, but are less well characterized compared with post-transplant lymphoproliferative disorders. The heterogeneous drug targets, various underlying disease indications, different drug combinations used and relatively low incidence render data collection and interpretation difficult. In this retrospective paper, we describe the clinicopathological characteristics of a larger single-center series of 72 immunomodulatory agent-related lymphoproliferative disorder cases. We divided the cases according to the therapy, administered in the year preceding diagnosis of a lymphoproliferative disorder, in an immunosuppressive drug, an immunomodulatory drug and a combination of immunosuppressive and immunomodulatory drugs group. We observed differences in "time to lymphoproliferative disorder development" with a shorter time for all the immunomodulatory drug-related cases combined (immunomodulatory and immunomodulatory + immunosuppressive = immunomodulatory-all) vs immunosuppressive-only (p = 0.0031). The proportion of malignant cases in patients receiving immunomodulatory therapy was, however, also significantly lower when compared with the immunosuppressive treated cases (43 vs 88%; p = 0.0184). The immunomodulatory/suppressive agent-related lymphoproliferative disorders were less often associated with the Epstein-Barr virus (EBV) (31 vs 66%; p = 1.829e-05) and the lymphoproliferative disorders incidence in the first year after immunomodulatory/immunosuppressive therapy initiation was lower (18 vs 41%; p = 0.04151)-compared with a published series of 140 post-transplant lymphoproliferative disorder cases from the same center. However, a similar histopathological spectrum from nondestructive, to polymorphic and monomorphic lesions as in post-transplant lymphoproliferative disorders is observed. With increasing use of immunosuppressive and especially immunomodulatory therapy, a higher incidence of immunomodulatory/suppressive agent-related lymphoproliferative disorders is to be expected. Life-long awareness for development of immunomodulatory/suppressive agent-related lymphoproliferative disorders with clinical follow-up and timely biopsies of suspicious lesions is required since these lymphoproliferative disorders arise both early after therapy initiation and many years later. Histopathological confirmation and correct classification is necessary to guide therapy and EBV ISH should be a part of routine pathological diagnostics.

Abstract
Autoimmune diseases and autoinflammatory diseases have a number of similar etiopathogenetic and clinical characteristics, including genetic predisposition and recurrent systemic inflammatory flares. The first phase of ADs involves innate immunity: by means of TLRs, autoantigen presentation, B and T cell recruitment and autoantibody synthesis. The second phase involves adaptive immunity, a self-sustaining process in which immune complexes containing nucleic acids and autoantibodies activate self-directed inflammation. The link between autoimmunity and autoinflammation is IL-1ß, which is crucial in connecting the innate immune response due to NLR activation and the adaptive immune responses of T and B cells. In conclusion, although ADs are still considered adaptive immunity-mediated disorders, there is increasing evidence that innate immunity and inflammasomes are also involved. The aim of this review is to highlight the link between the innate and adaptive immune mechanisms involved in autoimmune diseases.

Abstract
High salinity frequently causes inhibition and even failure in anaerobic digestion. To explore the impact of increasing NaCl concentrations on biogas production, and reveal the microbial community variations in response to high salinity stress, the Illumina high-throughput sequencing technology was employed. The results showed that a NaCl concentration of 20 g/L (H group) exhibited a similar level of VFAs and specific CO2 production rate with that in the blank group, thus indicating that the bacterial activity in acidogenesis might not be inhibited. However, the methanogenic activity in the H group was significantly affected compared with that in the blank group, causing a 42.2% decrease in CH4 production, a 37.12% reduction in the specific CH4 generation rate and a lower pH value. Illumina sequencing revealed that microbial communities between the blank and H groups were significantly different. Bacteroides, Clostridium and BA021 uncultured were the dominant species in the blank group while some halotolerant genera, such as Thermovirga, Soehngenia and Actinomyces, dominated and complemented the hydrolytic and acidogenetic abilities in the H group. Additionally, the most abundant archaeal species included Methanosaeta, Methanolinea, Methanospirillum and Methanoculleus in both groups, but hydrogenotrophic methanogens showed a lower resistance to high salinity than aceticlastic methanogens.

Abstract
In recent years, DAPK-related apoptosis-inducing protein kinase 2 (DRAK2) has emerged as a promising target for the treatment of a variety of autoimmune diseases and for the prevention of graft rejection after organ transplantation. However, medicinal chemistry optimization campaigns for the discovery of novel small-molecule inhibitors of DRAK2 have not yet been published. Screening of a proprietary compound library led to the discovery of a benzothiophene analogue that displays an affinity constant (Kd) value of 0.25 μM. Variation of the core scaffold and of the substitution pattern afforded a series of 5-arylthieno[2,3-b]pyridines with strong binding affinity (Kd = 0.008 μM for the most potent representative). These compounds also show promising activity in a functional biochemical DRAK2 enzyme assay, with an IC50 value of 0.029 μM for the most potent congener. Selectivity profiling of the most potent compounds revealed that they lack selectivity within the DAPK family of kinases. However, one of the less potent analogues is a selective ligand for DRAK2 and can be used as starting point for the synthesis of selective and potent DRAK2 inhibitors.

Abstract
PURPOSE OF REVIEW Long-term survival of liver transplant recipients is threatened by increased rates of de-novo malignancy and recurrence of hepatocellular carcinoma (HCC), both events tightly related to immunosuppression. RECENT FINDINGS There is accumulating evidence linking increased exposure to immunosuppressants and carcinogenesis, particularly concerning calcineurin inhibitors (CNIs), azathioprine and antilymphocyte agents. A recent study including 219 HCC transplanted patients showed that HCC recurrence rates were halved if a minimization of CNIs was applied within the first month after liver transplant. With mammalian target of rapamycin (mTOR) inhibitors as approved immunosuppressants for liver transplant patients, pooled data from several retrospective studies have suggested their possible benefit for reducing HCC recurrence. SUMMARY Randomized controlled trials with sufficiently long follow-up are needed to evaluate the influence of different immunosuppression protocols in preventing malignancy after LT. Currently, early minimization of CNIs with or without mTOR inhibitors or mycophenolate seems a rational strategy for patients with risk factors for de-novo malignancy or recurrence of HCC after liver transplant. A deeper understanding of the immunological pathways of rejection and cancer would allow for designing more specific and safer drugs, and thus to prevent cancer after liver transplant.

Corticosteroid therapy in regressive autism: a retrospective study of effects on the Frequency Modulated Auditory Evoked Response (FMAER), language, and behavior. BMC Neurol 2014; 14:70.

Abstract
Background Up to a third of children with Autism Spectrum Disorder (ASD) manifest regressive autism (R-ASD).They show normal early development followed by loss of language and social skills. Absent evidence-based therapies, anecdotal evidence suggests improvement following use of corticosteroids. This study examined the effects of corticosteroids for R-ASD children upon the 4 Hz frequency modulated evoked response (FMAER) arising from language cortex of the superior temporal gyrus (STG) and upon EEG background activity, language, and behavior. An untreated clinical convenience sample of ASD children served as control sample. Methods Twenty steroid-treated R-ASD (STAR) and 24 not-treated ASD patients (NSA), aged 3 - 5 years, were retrospectively identified from a large database. All study participants had two sequential FMAER and EEG studies;Landau-Kleffner syndrome diagnosis was excluded. All subjects’ records contained clinical receptive and expressive language ratings based upon a priori developed metrics. The STAR group additionally was scored behaviorally regarding symptom severity as based on the Diagnostic and Statistical Manual IV (DSM-IV) ASD criteria list. EEGs were visually scored for abnormalities. FMAER responses were assessed quantitatively by spectral analysis. Treated and untreated group means and standard deviations for the FMAER, EEG, language, and behavior, were compared by paired t-test and Fisher’s exact tests. Results The STAR group showed a significant increase in the 4 Hz FMAER spectral response and a significant reduction in response distortion compared to the NSA group. Star group subjects’ language ratings were significantly improved and more STAR than NSA group subjects showed significant language improvement. Most STAR group children showed significant behavioral improvement after treatment. STAR group language and behavior improvement was retained one year after treatment. Groups did not differ in terms of minor EEG abnormalities. Steroid treatment produced no lasting morbidity. Conclusions Steroid treatment was associated with a significantly increased FMAER response magnitude, reduction of FMAER response distortion, and improvement in language and behavior scores. This was not observed in the non-treated group. These pilot findings warrant a prospective randomized validation trial of steroid treatment for R-ASD utilizing FMAER, EEG, and standardized ASD, language and behavior measures, and a longer follow-up period.
