BACKGROUND/AIMS: Regulatory T cells (Tregs) can suppress immunologic damage in myocardial ischaemia/reperfusion injury (MIRI), however, the isolation and ex vivo expansion of these cells for clinical application remains challenging. Here, we investigated whether the IL-2/anti-IL-2 complex (IL-2C), a mediator of Treg expansion, can attenuate MIRI in mice. METHODS: Myocardial I/R was surgically induced in male C57BL/6 mice, aged 8-10 weeks, that were randomly assigned to 1) sham group (Sham), 2) Phosphate Buffered Saline (PBS), 3) IL-2-anti-IL-2 Ab complex (IL-2C), or 4) sham group, 5) PBS, 6) IL-2C after MIRI, or 7) IL-2C, 8) IL-2C+anti-CD25 mAbs, or 9) IL-2C; 10) IL-2C+anti-TGF-β1 mAbs, 11) IL-2C+anti-IL-10 mAbs...

Background: Results from the BEVA2007 trial, suggest that the metronomic chemotherapy regimen with dose-fractioned cisplatin and oral etoposide (mPE) +/- bevacizumab, a monoclonal antibody to the vascular endothelial growth factor (VEGF), shows anti-angiogenic and immunological effects and is a safe and active treatment for metastatic non-small cell lung cancer (mNSCLC) patients. We carried out a retrospective analysis aimed to evaluate the antitumor effects of this treatment in a subset of patients with squamous histology...

Signaling through the T cell receptor (TCR) regulates T cell homeostasis and effector functions. However, a full accounting of the TCR-coupled signaling networks and how their interplay determines specific functional outcomes remains elusive. Of particular interest are efforts over the last years to elucidate distinctive features of TCR signaling in regulatory T cells (Treg) that may account for some of their unique functional attributes as compared to conventional T (Tconv) cells. In this issue of the European Journal of Immunology, van Ham et al...

INTRODUCTION: During syphilis a compelling fight is engaged between the host's humoral and cellular immune responses that work to eliminate the infection and Treponema pallidum (T. pallidum) that manages to evade eradication and cause chronic infection. Different mechanisms are utilized by treponemes to overcome immunological response. Although penicillin (BPG) proved to be effective in quelling the early manifestations of the disease and consequently its contagiousness, questions remain about its ability to prevent the late complications and to provide a microbiological eradication in vivo...

Initiating breastfeeding within the first hour of life confers an important benefit in terms of child mortality and severe morbidity. Intestinal permeability to ingested macromolecules and immunoglobulins is limited to the first days of human life. These exchanges cease in the very early post-partum period but may increase beyond the neonatal period in response to local inflammation or introduction of a weaning food. From animal- and limited human-based observations, compelling evidence points out to breast milk cells also trafficking from mother to infant mucosal tissues and participating to the maternal microchimerism...

How tissue-resident macrophages (TRM) impact adaptive immune responses remains poorly understood. We report a novel mechanism by which TRMs regulate T cell activities at tissue sites. This mechanism was mediated by the complement receptor of immunoglobulin family (CRIg). Using animal models for autoimmune type 1 diabetes (T1D), we found that CRIg+ TRMs form a protective barrier surrounding pancreatic islets. Genetic ablation of CRIg exacerbated islet inflammation and local T cell activation. CRIg exhibited a dual function of attenuating early T cell activation and promoting the differentiation of Foxp3+ regulatory (Treg) cells...

The immunological effects of asbestos exposure on various lymphocytes such as the regulatory T cell (Treg), responder CD4+ T helper cell (Tresp), CD8+ cytotoxic T lymphocytes (CTL), and natural killer (NK) cells were investigated. Results show that asbestos exposure impairs antitumor immunity through enhancement of regulatory T cell function and volume, reduction of CXCR3 chemokine receptor in responder CD4+ T helper cells, and impairment of the killing activities of CD8+ cytotoxic T lymphocytes (CTL) and NK cells...

Since the etiology of periodontitis in humans is not fully understood, genetic mouse models may pinpoint indispensable genes for optimal immunological protection of the periodontium against tissue destruction. This review describes the current knowledge of genes that are involved for a proper maintenance of a healthy periodontium in mice. Null mutations of genes required for leukocyte cell-cell recognition and extravasation (e.g., Icam-1, P-selectin, Beta2-integrin/Cd18), for pathogen recognition and killing (e...

Skin dendritic cells (DCs) are divided into several subsets with distinctive functions. This study shows a previously unappreciated role of dermal CD11b-type Langerin(-) DCs in maintaining immunological self-tolerance after UVB exposure. After UVB exposure, dermal CD11b-type Langerin(-) DCs upregulated surface CD86 expression, induced proliferation of Foxp3(+) regulatory T (Treg) cells without exogenous Ags, and upregulated a set of genes associated with immunological tolerance. This Treg-expansion activity was significantly hampered by CD80/CD86 blockade in vivo...

BACKGROUND: Store-operated Ca(2+) entry (SOCE) through Ca(2+) release-activated Ca(2+) (CRAC) channels is an essential signaling pathway in many cell types. CRAC channels are formed by ORAI1, ORAI2 and ORAI3 proteins and activated by stromal interaction molecule 1 (STIM1) and STIM2. Mutations in ORAI1 and STIM1 genes that abolish SOCE cause a combined immunodeficiency (CID) syndrome that is accompanied by autoimmunity and non-immunological symptoms. OBJECTIVE: Molecular and immunological analysis of patients with CID, anhidrosis and ectodermal dysplasia of unknown etiology...

Advances in reproductive medicine have significantly increased the success of fertility treatments. Nevertheless, some women experience recurrent implantation failure (RIF) after in-vitro fertilization (IVF) or recurrent pregnancy loss (RPL). Imbalances in the immune system and failure to achieve immune tolerance to the foetus have been implicated as potentially modifiable causes of idiopathic RIF and RPL. As such, women are increasingly being treated with immunomodulatory agents in an attempt to achieve a successful pregnancy...

Use of high-dose, post-transplant cyclophosphamide (PTCy) results in low rates of graft-versus-host-disease (GVHD) and favorable immune reconstitution, although with higher rates of relapse and somewhat high rates of graft failure. We hypothesized that permissible dose reduction of PTCy might be feasible. The current study attempts to establish a murine model and focus on regulatory T cells (Tregs) to clarify the immunological mechanisms for GVHD prevention by low-dose PTCy. In addition, a prospective, clinical cohort study in haploidentical, T-cell replete transplantation is initiated to support the rational...

Boys present with higher proportions of immature/naïve CD5(+) B cells than girls up to 3 years of age. Boys also have higher fractions of regulatory T cells (Tregs) in early infancy, but the mechanisms for these sex-related differences are unknown. In the prospective FARMFLORA follow-up study of 23 boys and 25 girls, we investigated if these immunological differences remained at 8 years of age. We also examined if testosterone or dihydrotestosterone (DHT) levels at birth and at 8 years of age were associated with immune maturation...

Short-term outcomes of solid organ transplantation have improved dramatically over the past several decades; however, long-term survival has remained static over the same time period, and chronic rejection remains a major cause of graft failure. The importance of donor, or 'passenger', lymphocytes to the induction of tolerance to allografts was recognized in the 1990s; however, their precise contribution to graft acceptance or rejection has not been elucidated. Recently, specialized populations of tissue-resident lymphocytes in nonlymphoid organs have been described...

BACKGROUND AND PURPOSE: Resistance to endocrine therapies in hormone receptor (HR)-positive breast cancer is a significant challenge. Prior studies have shown that low-dose oral cyclophosphamide can transiently deplete regulatory T cells (Tregs) and improve anti-tumor immunity. We investigated the combination of exemestane with cyclophosphamide in patients with advanced HR-positive breast cancer and assessed changes in circulating immune cell subsets. METHODS: This was a single-arm phase II trial of exemestane with cyclophosphamide in patients with metastatic HR-positive/HER2-negative breast cancer who had progressed on prior endocrine therapy (ClinicalTrials...

Failing immunological tolerance for critical self-antigens is the problem underlying most chronic inflammatory diseases of humans. Despite the success of novel immunosuppressive biological drugs, the so-called biologics, in the treatment of diseases such rheumatoid arthritis (RA) and type 1 diabetes, none of these approaches does lead to a permanent state of medicine free disease remission. Therefore, there is a need for therapies that restore physiological mechanisms of self-tolerance. Heat shock proteins (HSPs) have shown disease suppressive activities in many models of experimental autoimmune diseases through the induction of regulatory T cells (Tregs)...

Allergic rhinitis (AR) and chronic rhinosinusitis with nasal polyps (CRSwNP) are inflammatory diseases of the upper airway, with a similar immunologic profile, characterized by aberrant and persistent type 2 inflammation. One cell population that has been identified as altered in both disease types is regulatory T cell (Treg). Tregs have the capacity to modulate T-effector function and suppress inflammatory cytokine production in a broad range of cell types. Given the ability of Tregs to control inflammation, the role of Tregs in respiratory diseases has attracted much attention...

Pathogenesis of autoimmune disorders, including multiple sclerosis (MS), has been linked to an alteration of the resident microbial commensal community and of the interplay between the microbiota and the immune system. Dietary components such as fiber, acting on microbiota composition, could, in principle, result in immune modulation and, thus, could be used to obtain beneficial outcomes for patients. We verified this hypothesis in a pilot study involving two groups of clinically similar relapsing-remitting (RR) MS patients who had undergone either a high-vegetable/low-protein diet (HV/LP diet group; N = 10) or a "Western Diet" (WD group; N = 10) for at least 12 months...
