This study aimed to explore the roles of microRNAs (miRNAs) in calf rumen development during early life. Rumen tissues were collected from 16 calves (8 at pre-weaning and 8 at post-weaning) for miRNA-sequencing, differential expression (DE), miRNA weighted gene co-expression network (WGCNA) and miRNA-mRNA co-expression analyses. 295 miRNAs were identified. Bta-miR-143, miR-26a, miR-145 and miR-27b were the most abundantly expressed. 122 miRNAs were significantly DE between the pre- and post-weaning periods and the most up- and down-regulated miRNAs were bta-miR-29b and bta-miR-493, respectively...

The primary function of myeloid derived suppressor cells (MDSCs) is reflected in their immune modulatory role in several immune-mediated diseases. In IgG4-related disease (IgG4-RD), it has been hypothesized that there are selective regulatory defects that lead to a Th2 bias immune response. Herein we have taken advantage of a large cohort of patients with IgG4-related sclerosing cholangitis (IgG4-SC), the most common extra-pancreatic involvement of IgG4-RD, as well as controls consisting of primary sclerosing cholangitis (PSC), autoimmune hepatitis (AIH) and healthy volunteers, to study MDSC...

In addition to the crucial role in promoting the growth of tumor vessels, vascular endothelial growth factor (VEGF) is also immunosuppressive. VEGF can inhibit the function of T cells, increase the recruitment of regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs), and hinder the differentiation and activation of dendritic cells (DCs). Recent studies have investigated the role of antiangiogenic agents in antitumor immunity, especially in recent 3 years. Therefore, it is necessary to update the role of targeting VEGF/VEGFR in antitumor immunity...

T follicular regulatory (Tfr) cells are a population of CD4+ T cells that express regulatory T cell markers and have been shown to suppress humoral immunity. However, the precise mechanisms and location of Tfr-mediated suppression in the lymph node (LN) microenvironment are unknown. Using highly multiplexed quantitative imaging and functional assays, we examined the spatial distribution, suppressive function, and preferred interacting partners of Tfr cells in human mesenteric LNs. We find that the majority of Tfr cells express low levels of PD-1 and reside at the border between the T cell zone and B cell follicle, with very few found in the germinal centers (GCs)...

PURPOSE: Allogeneic haematopoietic stem-cell transplantation (HSCT) is a curative treatment for many haematologic cancers. Use of haploidentical (mismatched) donors increases HSCT availability but is limited by severe graft-versus-host disease (GvHD) and delayed immune reconstitution. Alloanergization of donor T-cells is a simple approach to rebuild immunity whilst limiting GvHD after haploidentical HSCT but the optimal T-cell dose and impact on immune reconstitution remain unknown.  Experimental Design: We performed a multicentre Phase 1 trial of alloanergized donor lymphocyte infusion (aDLI) after CD34-selected myeloablative haploidentical HSCT...

CD8+ T-regulatory cells are progressively emerging as crucial components of immune system. The previous report suggests the presence of FOXP3-positive CD8+ Treg cells, similar to CD4+ Tregs, in cancer patients which produce high levels of IL10 and TGFβ for its immunosuppressive activities. At an early stage of tumor development, we have identified a subset of FOXP3-negative CD8+ CD25+ KIR+ CD127- a Treg-like subset which is essentially IFNγ-positive. However, this early induced CD8+ CD25+ CD127- T cell subset certainly distinct from the IFNγ+ CD8+ T-effecter cells...

Hemophagocytic lymfohistiocytosis (HLH) is rare, life-threatening condition, characterized by excessive activation of immune system with subsequent proinflammatory state resulting in multiorgan failure. Most frequently, it appears in infancy as a primary disorder caused by mutation of immune-regulatory genes. Increasingly, HLH is being diagnosed as a secondary - adult - form, which occurs as a result of aberrant immune response. Viral or bacterial systemic infections, malignancy with a predominance of lymphoproliferative disorders and autoimmune diseases are the most common triggers...

Myeloid-derived suppressor cells (MDSCs) expand in maternal peripheral blood and cord blood during normal pregnancy to maintain maternal-fetal tolerance. Here we investigated the expansion and function of MDSCs in preeclampsia (PE) patients. Maternal peripheral blood mononuclear cells (PBMCs) and cord blood mononuclear cells (CBMCs) were sampled from healthy pregnant women and PE patients, and analyzed for the frequencies and phenotypes of MDSCs and T cells. Serum levels of key human MDSC effector enzymes were measured using appropriate detection kits...

Myeloid-derived suppressor cells (MDSCs) play roles in immune regulation during neoplastic and non-neoplastic inflammatory responses. This immune regulatory function is directed mainly toward T cells. However, MDSCs also regulate other cell populations, including B cells, during inflammatory responses. Indeed, B cells are essential for antibody-mediated immune responses. MDSCs regulate B cell immune responses directly via expression of effector molecules and indirectly by controlling other immune regulatory cells...

Autoimmunity develops when self-tolerance mechanisms are failing to protect healthy tissue. A sustained reaction to self is generated, which includes the generation of effector cells and molecules that destroy tissues. A way to restore this intrinsic tolerance is through immune modulation that aims at refurbishing this immunologically naïve or unresponsive state, thereby decreasing the aberrant immune reaction taking place. One major cytokine has been shown to play a pivotal role in several autoimmune diseases such as rheumatoid arthritis (RA) and multiple sclerosis (MS): tumor necrosis factor alpha (TNFα) modulates the induction and maintenance of an inflammatory process and it comes in two variants, soluble TNF (solTNF) and transmembrane bound TNF (tmTNF)...

In untreated HIV infection, the efficacy of T cell responses decreases over the disease course, resulting in disease progression. The reasons for this development are not completely understood. However, immunosuppressive cells are supposedly crucially involved. Treatment strategies to avoid the induction of these cells preserve immune functions and are therefore the object of intense research efforts. In this study, we assessed the effect of treatment intensification [=5-drug antiretroviral therapy (ART)] on the development of suppressive cell subsets...

Sex steroidal hormones coordinate the development and maintenance of tissue architecture in many organs, including the central nervous systems (CNS). Within the CNS, sex steroids regulate the morphology, physiology, and behavior of a wide variety of neural cells including, but not limited to, neurons, glia, endothelial cells, and immune cells. Sex steroids spatially and temporally control distinct molecular networks, that, in turn modulate neural activity, synaptic plasticity, growth factor expression and function, nutrient exchange, cellular proliferation, and apoptosis...

Lymphatic vessels remove and transport excess interstitial fluid to lymph nodes (LNs) for fluid balance and immune protection. LNs are typically surrounded by perinodal adipose tissue (PAT). However, PAT is a blood vessel-rich but lymphatic-rare tissue; therefore, how excess fluid in PAT is removed remains unclear. Using C57BL/6 mice, fluorescent dye tracing and transmission electron microscopy results suggest that fluid in PAT can travel to the LN via collagen I+ channels (PAT-LN conduits), merge into a collagen-rich space between the PAT and LN capsule (PAT-LN sinus), and may enter the LN via the LN capsule-associated conduits...

The progressive damage in rheumatoid arthritis (RA) has been linked to an increase in inflammatory Th1/Th17 cells and a decrease in number or function of immunomodulatory regulatory T cells (Tregs). Many therapies that are effective in RA are shown to affect Th1/Th17 cells and/or Tregs. One such therapy, abatacept, utilizes a physiologic immunomodulatory molecule called cytotoxic lymphocyte antigen-4 (CTLA-4) which causes contact-dependent inhibition of inflammatory T-cell activation. Recent advances in CTLA-4 research has uncovered the method by which this occurs physiologically but the actions of the CTLA-4Ig fusion protein are still not fully understood...

In recent years, it has been recognized that regulatory T cells (Tregs) play a critical role in maintaining immune tolerance. Moreover, the expression of two markers named Helios and neurophilin-1 (NRP-1) has been highlighted in such cells. Helios, an intracellular transcription marker, largely differentiates twomost operative sub group of Tregs, namely naturally occurring (nTreg) and induced (iTreg) Tregs, and NRP-1 is reckoned as a membranous activity marker of Tregs. We aimed to count peripheral mononuclear cells expressing such markers in a group of type 1 diabetes patients to elucidate the possible role of Tregs in the pathogenesis of such disease and its complications...

OBJECTIVE: Autoimmune hepatitis (AIH) is an inflammatory disease caused by aberrant immune response to hepatic self-antigens in which regulatory T cells (Tregs) are critical to maintain immunosupression. Soluble form of Fibrinogen-like protein 2 (sFGL2), a novel effector molecule of Treg is rarely investigated in AIH. Here, we dissected the role of sFGL2 in the autoimmune hepatitis and its potential mechanism underlying AIH progression. METHODS: Plasma and intrahepatic sFGL2 levels, as well as Treg cells were measured in both AIH patients and experimental autoimmune hepatitis (EAH) mice...

PROBLEM: The lymphatic vasculature controls leukocytes trafficking and limits the adaptive immune response. In previous models of preeclampsia (PE), defective immune function caused by disruption of lymphangiogenesis was shown to be involved in the disease pathophysiology. Especially, the dysfunction of regulatory T cells (Treg) at the maternal-fetal interface may be one of the causes of severe PE. In particular, activation of Tregs to obtain immune tolerance requires adequate antigen presentation through the lymphatic system...
