Combining Understanding of Immunological Mechanisms and Genetic Variants Toward Development of Personalized Medicine for Psoriasis Patients
Conclusion Although GWAS contributed insight into the utility of the genotype biomarker to treatment selection, adequately powered prospective studies will be required before clinical application of pharmacogenomics can become a reality. Genotype and phenotype assessment should be facilitated by the availability of detailed molecular analyses and data integration. Careful assessment of prospective GWAS data is essential to integrate findings into the clinical decision-making process, and thereby optimizing the treatment of patients with psoriasis in the future. Author Contributions BY, NG, and WY performed the project. ...

TRAIL-R1 and TRAIL-R2 Mediate TRAIL-Dependent Apoptosis in Activated Primary Human B Lymphocytes
In conclusion, this study provides a systematic analysis of the expression of TRAIL-Rs in human primary B cells and of their capacity to signal and induce apoptosis. This dataset forms a basis to further study and understand the dysregulation of TRAIL-Rs and TRAIL expression observed in autoimmune diseases. Additionally, it will be important to foresee potential bystander immunomodulation when TRAIL-R agonists are used in cancer treatment. Introduction The homeostasis of humoral immunity requires a tight control of generation, survival, activation and maturation of B lymphocytes. Therefore, pro-survival and pro-apo...

Comparison of Three Immunoassays for the Detection of Myositis Specific Antibodies
Conclusion: The data hold promise for advancements in standardization of MSA assays as well as for the potential inclusion of MSA in future classification criteria. Introduction Myositis specific (MSA) and myositis associated antibodies (MAA) have been used as an aid in the diagnosis of idiopathic inflammatory myopathies (IIM) for decades (1). Since many of the MSA (e.g., anti-synthetase antibodies), partly depending on the screening dilution, are accompanied by limited sensitivity of the indirect immunofluorescence (IIF) test, this method has limited utility as a screening test for suspected myositis (2–6)...

Systemic Lupus Erythematosus With Isolated Psychiatric Symptoms and Antinuclear Antibody Detection in the Cerebrospinal Fluid
Conclusion: Some patients with psychiatric syndromes and increased ANA titers may suffer from psychiatric variants of SLE, even if the American College of Rheumatology criteria for SLE are not met. Whether the psychiatric symptoms in our patient represent a prodromal stage with the later manifestation of full-blown SLE or a subtype of SLE with isolated CNS involvement remains unclear. Regardless, early diagnosis and initiation of immunosuppressive treatment are essential steps in preventing further disease progression and organ damage. Intrathecal ANAs with extractable nuclear antigen differentiation may be a more sensitiv...

Antibiotic-Induced Disruption of Gut Microbiota Alters Local Metabolomes and Immune Responses
In conclusion, our study indicated that 3 weeks antibiotic administration induced elevated expression of many cytokines in mouse colon, suggesting that there might be a direct interaction between antibiotics and host tissue. Furthermore, different antibiotics used can lead to different effects on mouse models. Broad spectrum antibiotic enrofloxacin had a stronger effect on the cytokines response in the colon. Vancomycin can induce significant changes in composition and metabolic profiling of gut microbiota. Compared to enrofloxacin and vancomycin, polymixin B sulfate had a weakest effect. The differences observed in compos...

Scurfy Mice Develop Features of Connective Tissue Disease Overlap Syndrome and Mixed Connective Tissue Disease in the Absence of Regulatory T Cells
Discussion Treg represent a lineage of T cells which play a fundamental role in maintaining humoral tolerance in the periphery. This subset of “suppressor T cells” is identified as FoxP3-expressing CD4+ T cells (16, 17). The unrestrained expression of FoxP3 is essential for the development and function of Treg (4). Accordingly, a disruption of the Foxp3 gene in scurfy mice results in an autoimmune lymphoproliferative disorder with fatal multi-organ inflammation (18). Since the causative mutation occurs in orthologous genes, the scurfy phenotype is indicated as the murine equivalent of the human IPEX sy...

Geniposide Alleviates Glucocorticoid-Induced Inhibition of Osteogenic Differentiation in MC3T3-E1 Cells by ERK Pathway
Conclusion In summary, we demonstrated that geniposide alleviated GC-induced osteogenic suppression in MC3T3-E1 cells. The effects of geniposide were at least partially associated with activating ERK signaling pathway via GLP-1 receptor. Geniposide might be a potential therapeutic agent for protection against GC-induced osteoporosis. Author Contributions BX, DX, CZ, and LW participated in research design. BX, JW, YL, XW, and ZZ conducted the experiments. BX, DX, and LW contributed new reagents or analytic tools and wrote or contributed to the writing of the manuscript.

Focused Ultrasound Improves NK-92MI Cells Infiltration Into Tumors
Conclusion In conclusion, we demonstrated that the combination of FUS and microbubbles could increase the NK-92MI cells’ infiltration into tumors in this study. The combination of FUS and NK-92MI had a much better therapeutic effect when compared with the PBS group, but no superior therapeutic effect when compared with the NK-92MI group. In total, FUS and microbubbles can improve NK cells’ infiltration into tumors, but future work is still needed to improve NK-92MI cells’ delivery efficiency for solid tumor treatment. Ethics Statement This study was carried out in accordance with the recommendations...

A Systematic Review on Predisposition to Lymphoid (B and T cell) Neoplasias in Patients With Primary Immunodeficiencies and Immune Dysregulatory Disorders (Inborn Errors of Immunity)
Conclusions Though this is not a comprehensive summary of malignancies in PIDDs, or even lymphoproliferative disease in this area, this review summarizes the Medline-indexed published reports of B and T lymphomas in patients with PIDDs. This report highlights the diversity of malignant lymphoproliferative disorders in setting of PIDDs, and its associated challenges of diagnosis and treatment. The pathological classification and nomenclature for the lymphoid malignancies with variably reported and postulated underlying mechanisms were inconsistent and inadequate for many of these published reports. A wide range of treatmen...
