Jochen H O Hoffmann, Alexander H Enk
Based on their immunomodulatory properties, high-dose intravenous immunoglobulins (IVIGs) are successfully used in the treatment of various dermatological autoimmune diseases, in particular pemphigus vulgaris and dermatomyositis. In autoimmune bullous diseases, IVIGs can be used in an adjuvant setting (second- or third-line therapy) once combined immunosuppressive regimens have failed. In dermatomyositis, IVIGs may already be employed as an adjuvant second-line therapy after failure of corticosteroid monotherapy...

Oestrogen treatments are neuroprotective in a variety of neurodegenerative disease models. Selective oestrogen receptor modifiers are needed to optimize beneficial effects while minimizing adverse effects to achieve neuroprotection in chronic diseases. Oestrogen receptor beta (ERβ) ligands are potential candidates. In the multiple sclerosis model chronic experimental autoimmune encephalomyelitis, ERβ-ligand treatment is neuroprotective, but mechanisms underlying this neuroprotection remain unclear. Specifically, whether there are direct effects of ERβ-ligand on CD11c+ microglia, myeloid dendritic cells or macrophages in vivo during disease is unknown...

Liposomal spherical nucleic acids (LSNAs) are an attractive therapeutic platform for gene regulation and immunomodulation due to their biocompatibility, chemically tunable structures, and ability to enter cells rapidly without the need for ancillary transfection agents. Such structures consist of small (<100 nm) liposomal cores functionalized with a dense, highly oriented nucleic acid shell, both of which are key components in facilitating their biological activity. Here, the properties of LSNAs synthesized using conventional methods, anchoring cholesterol terminated oligonucleotides into a liposomal core, are compared to LSNAs made by directly modifying the surface of a liposomal core containing azide-functionalized lipids with dibenzocyclooctyl-terminated oligonucleotides...

REVIEW
Silvia Monticelli, Cristina Leoni
Mast cells are tissue-resident, innate immune cells present in most tissues of the body and are important effector and immunomodulatory cells. Differentiated mast cells typically are characterized by the surface expression of the receptors KIT and FcεRI, the latter especially being important for stimulation through IgE antibodies, although these cells have the ability to respond to a wide variety of environmental signals, to which they can variably react by releasing pre-stored or de novo-synthesized mediators or both...

Introduction: Chronic wounds remain a major clinical challenge. Human cryopreserved viable amniotic membrane (hCVAM) is among the most successful therapies, but the mechanisms of action remain loosely defined. Because proper regulation of macrophage behavior is critical for wound healing with biomaterial therapies, we hypothesized that hCVAM would positively regulate macrophage behavior in vitro, and that soluble factors released from the hCVAM would be important for this effect. Materials and Methods: Primary human pro-inflammatory (M1) macrophages were seeded directly onto intact hCVAM or cultured in separation via transwell inserts (Soluble Factors) in the presence of pro-inflammatory stimuli (interferon-γ and lipopolysaccharide) to simulate the chronic wound environment...

Nowadays, cancer immunotherapy is a promising strategy in solid tumour treatment. It has become a breakthrough in achieving long-term survival in many advanced cases. The essence of modern immunotherapy is to improve the host antitumour immune defence. Currently, it is critically important to determine the biomarkers that could be helpful in planning this type of individual therapy. It has turned out that an important prognostic factor is the evaluation of inflammatory infiltration of the tumour mass, including the characteristics of populations of lymphocytes and macrophages, and the expression of suppressive and regulatory molecules...

Vitamin D (VD) has exhibited immunomodulatory role in the pathogenesis of preeclampsia. We hypothesize VD potentiate nifedipine treatment for preeclampsia by shortened the time to control blood pressure and prolong time before subsequent hypertensive crisis. We conduct a randomized trial of 683 primigravid women with preeclampsia, who were assigned to different treatment groups, either nifedipine+placebo or nifedipine+VD orally, by random after screening. Primary endpoints include time to control hypertension and time before another hypertensive crisis...

Methylprednisolone (MP) has been recommended as a standard drug in MS therapies. We previously demonstrated that IFNβ-secreting human bone marrow-derived mesenchymal stem cells (MSCs-IFNβ) exert immunomodulatory effects in experimental autoimmune encephalomyelitic (EAE) mice. In this study, we evaluated whether a combined treatment of MP and MSCs-IFNβ had enhanced therapeutic effects on EAE mice. The combination treatment resulted in enhanced immunomodulatory effects, including reduced production of pro-inflammatory cytokines and increased production of anti-inflammatory cytokines...

Industrialized countries have registered epidemic rates on allergic diseases, such as hay fever, asthma, eczema, and food allergies. The Hygiene Hypothesis was born from work made by Dr. David Strachan, who observed that younger siblings were less susceptible to eczema and asthma, and proposed that this was a result of increased transmission of infectious agents via unhygienic practices within a household. This initial hypothesis was then reframed as the old friends/microbiota hypothesis, implicating non-pathogenic commensal microorganisms as the source of immunomodulatory signals necessary to prevent immune-mediated chronic disorders...

BACKGROUND: Effective therapy of Acute Lung Injury (ALI) is still a major scientific and clinical problem. To define novel therapeutic strategies for sequelae of blunt chest trauma (TxT) like ALI/Acute Respiratory Distress Syndrome, we have investigated the immunomodulatory and regenerative effects of a single dose of ex vivo expanded human or rat mesenchymal stromal cells (hMSCs/rMSCs) with or without priming, immediately after the induction of TxT in Wistar rats. METHODS: We analyzed the histological score of lung injury, the cell count of the broncho alveolar lavage fluid (BAL), the change in local and systemic cytokine level and the recovery of the administered cells 24 h and 5 days post trauma...

Hidradenitis suppurativa (HS) is an inflammatory skin disease with poorly understood immunopathogenic mechanisms. LL-37 is an antimicrobial peptide, which is transcribed from the CAMP (cathelicidin antimicrobial peptide) gene. Previous reports showed upregulated levels of CAMP and LL-37 in HS lesions and therefore the aim of this study was to compare levels of LL-37 in HS to other inflammatory skin diseases and to establish immunomodulatory functions of LL-37 in HS. We confirm an upregulation of the LL-37 peptide in lesional HS skin with comparable levels as in psoriasis patients and are able to positively correlate the presence of LL-37 in HS with the presence of T cells, macrophages, neutrophils, IFNγ, IL-17, IL-23, TNFα, IL-32 and IL-1β...

Considerable progress has been made in the treatment of multiple myeloma in the past decade with median survival for the disease improving significantly. This has come through a combination of better understanding of the disease biology and coordinated research into new treatment approaches including better supportive care. However, patients eventually become refractory to available treatments and succumb to the disease, highlighting the need to develop new treatment approaches. The genetic heterogeneity in the disease and clonal evolution under treatment pressure underlie the development of resistance, underscoring the need to develop more effective therapies that can eradicate the disease at initial treatment as well as the need for new classes of drugs with varying mechanisms of action...

Multiple myeloma is the second most frequent hematological disease. The introduction of melphalan as high-dose therapy followed by autologous hematopoietic cell transplantation (HDT/ASCT) for young patients and the availability of novel agents for young and elderly patients with multiple myeloma have dramatically changed the perspective of treatment. However, further research is necessary if we want definitively to cure the disease. Treatment goals for transplant-eligible and non-transplant-eligible patients should be to prolong survival by achieving the best possible response while ensuring quality of life...

Immunometabolism, which has important implications in cancer biology, has emerged as a major regulator of different immune cell types. Various factors that integrate metabolic switches within immune cells with signal directed program that promote or inhibit their functions remain largely unidentified. Furthermore, sex differences are known to exist in immune functions and cancer incidences in the body and sex steroid hormones are integral component of these differences. However, factors that mediate such differences, and the potential link between the two fundamental aspects of immune cell biology that contributes to sex differences in health and disease remain unexplored...

Polysaccharides from Collybia radicata mushroom (CRP) possess many functions, such as antiviral, anti-aging and hypolipidemic activities. However, little is known about their immunomodulatory activity. To address this issue, we did a thorough research into their immune effects on murine macrophages. The results showed that the 14942Da polysaccharide not only obviously improved the proliferation and phagocytosis of macrophages, but also induced the secretion of nitric oxide (NO), inducible nitric oxide synthase (iNOS) and cytokines, such as tumor necrosis factor-α (TNF-α) and interleukin factors (IL-1β, IL-6 and IL-10)...

RATIONALE: Pulmonary fibrosis is a chronic progressive lung disease with few treatments. Human mesenchymal stem cells (MSC) have been shown to be beneficial to pulmonary fibrosis as they have the immunomodulatory capacity. However, there is no reliable model to test the therapeutic effect of human MSC in vivo. METHODS: Here, to mimic pulmonary fibrosis in humans, we established a novel bleomycin-induced pulmonary fibrosis model in humanized mice. Based on this model, the benefit of human MSC to pulmonary fibrosis and underlying mechanism were investigated...
