"I Put Her in the Baby Stroller and Left": The Escape Route From Violence to a Domestic Violence Shelter for Mothers and Children.

Little is known about mothers' and children's escape from violence and its aftermath when living in secure accommodation, especially with regard to children. The aim is to investigate mothers' experiences of their escape, and their considerations regarding the well-being of their young children before or during their escape, based on 14 interviews. Using a narrative thematic analysis, the results show that the escape was often planned, but that the planning horizon varies.

Modulation of lytic molecules restrain serial killing in γδ T lymphocytes.

γδ T cells play a pivotal role in protection against various types of infections and tumours, from early childhood on and throughout life. They consist of several subsets characterised by adaptive and innate-like functions, with Vγ9Vδ2 being the largest subset in human peripheral blood. Although these cells show signs of cytotoxicity, their modus operandi remains poorly understood.

Vulnerability Factors among Women Victimized by Intimate Partner Violence and the Presence of Children.

This study aimed to a) examine the presence of children in relation to victim vulnerability factors and assessed risk for intimate partner violence (IPV) re-victimization, and b) examine the police response, in terms of risk management, in IPV cases with and without children, respectively. Data from a sample of 1407 women who had reported IPV victimization to the Swedish police was analyzed. The material consisted of risk assessments conducted by the police using the Swedish version of the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) checklist, as well as the recommended risk management strategies.

Comprehensive flow cytometric reference intervals of leukocyte subsets from six study centers across Europe.

A group of European FOCIS Centers of Excellence adapted panels of the Human Immunophenotyping Consortium (HIPC) for whole blood analysis. Using four core panels [T/regulatory T cell/B/natural killer (T/T /B/NK) and myeloid cells] the main leukocyte populations were analyzed in a clinical-diagnostic setting in a harmonized manner across different platforms. As a first step, the consortium presents here the absolute and relative frequencies of the leukocyte subpopulations in the peripheral blood of more than 300 healthy volunteers across six different European centers.

Magnitude and Functional Profile of the Human CD4 T Cell Response throughout Primary Immunization with Tick-Borne Encephalitis Virus Vaccine.

Tick-borne encephalitis (TBE) is a viral infection of the CNS caused by TBE virus. With no specific treatment available, the only protection is a formalin-inactivated whole virus vaccine. Primary immunization with European TBE vaccines, as recommended by the manufacturers, consists of three vaccine doses administered within a 1-y period.

Individualization of Hematopoietic Stem Cell Transplantation Using Alpha/Beta T-Cell Depletion.

Allogeneic hematopoietic stem cell transplantation (HSCT) is associated with several potentially lethal complications. Higher levels of CD3+ T-cells in the graft have been associated with increased risk of graft-versus-host disease (GVHD), but also beneficial graft-versus-leukemia effect and reduced infections. To tackle post-transplant complications, donor lymphocyte infusions have been used but with an increased risk of GVHD.

Ex Vivo Generation of Donor Antigen-Specific Immunomodulatory Cells: A Comparison Study of Anti-CD80/86 mAbs and CTLA4-lg Costimulatory Blockade.

Adoptive transfer of alloantigen-specific immunomodulatory cells generated ex vivo with anti-CD80/CD86 mAbs (2D10.4/IT2.2) holds promise for operational tolerance after transplantation.

Functionality testing of stem cell grafts to predict infectious complications after allogeneic hematopoietic stem cell transplantation.

Background And Objectives: Allogeneic hematopoietic stem cell transplantation (HSCT) is a routine clinical procedure performed to treat patients with haematological malignancies, primary immune deficiencies or metabolic disorders. Infections during lymphopenia after allogeneic HSCT are associated with high mortality and morbidity. Typical infectious agents are Epstein-Barr virus, cytomegalovirus, herpes simplex virus, varicella-zoster virus and fungi.

Leukemic Stem Cell Quantification in Newly Diagnosed Patients With Chronic Myeloid Leukemia Predicts Response to Nilotinib Therapy.

Purpose: Leukemic stem cells (LSCs) may harbor important resistance to tyrosine kinase inhibitors in chronic myelogenous leukemia (CML). We identified Philadelphia chromosome (Ph)-positive CD34(+)CD38(-) bone marrow cells (here denoted LSCs) and addressed their response-predictive value in patients with CML (n = 48) subjected to nilotinib in the ENEST1st trial (NCT01061177).

Experimental Design: Two flow cytometry-based cell sorting methods were used with multiparameter-directed CD45- (MPFC) and BCR-ABL1 probe-linked (FISH) identification of Ph-positive cells, respectively.

Alpha/beta T-cell depleted grafts as an immunological booster to treat graft failure after hematopoietic stem cell transplantation with HLA-matched related and unrelated donors.

Allogeneic hematopoietic stem cell transplantation is associated with several complications and risk factors, for example, graft versus host disease (GVHD), viral infections, relapse, and graft rejection. While high levels of CD3+ cells in grafts can contribute to GVHD, they also promote the graft versus leukemia (GVL) effect. Infusions of extra lymphocytes from the original stem cell donor can be used as a treatment after transplantation for relapse or poor immune reconstitution but also they increase the risk for GVHD.

Novel STAT3 mutation causing hyper-IgE syndrome: studies of the clinical course and immunopathology.

Purpose: Reporting a clinical case with a novel mutation in the signal transducer and activator of transcription 3 (STAT3) gene resulting in autosomal dominant hyper-immunoglobulin E syndrome (AD-HIES). Here we also had the opportunity to perform in-depth immunologic investigations to further understand the immunopathology of this primary immunodeficiency.

Methods: The patient, a baby boy, was clinically assessed according to the scoring system developed by Grimbacher et al.

Impact of malignant stem cell burden on therapy outcome in newly diagnosed chronic myeloid leukemia patients.

Chronic myeloid leukemia (CML) stem cells appear resistant to tyrosine kinase inhibitors (TKIs) in vitro, but their impact and drug sensitivity in vivo has not been systematically assessed. We prospectively analyzed the proportion of Philadelphia chromosome-positive leukemic stem cells (LSCs, Ph+CD34+CD38-) and progenitor cells (LPCs, Ph+CD34+CD38+) from 46 newly diagnosed CML patients both at the diagnosis and during imatinib or dasatinib therapy (ClinicalTrials.gov NCT00852566).

Altered immunoregulatory profile during anti-tumour necrosis factor treatment of patients with inflammatory bowel disease.

Inflammatory bowel disease (IBD) can be treated effectively by anti-tumour necrosis factor (TNF) therapy. We set out to investigate the unclear immunoregulatory mechanisms of the treatment. Thirty-four patients with IBD treated with anti-TNF were included.

Allergic asthmatics show divergent lipid mediator profiles from healthy controls both at baseline and following birch pollen provocation.

Background: Asthma is a respiratory tract disorder characterized by airway hyper-reactivity and chronic inflammation. Allergic asthma is associated with the production of allergen-specific IgE and expansion of allergen-specific T-cell populations. Progression of allergic inflammation is driven by T-helper type 2 (Th2) mediators and is associated with alterations in the levels of lipid mediators.

Mesenchymal stem cells inhibit thymic reconstitution after allogeneic cord blood transplantation.

Cord blood (CB) as a source of stem cells has been a successful addition to the field of allogeneic stem cell transplantation (ASCT). The increased human leukocyte antigen (HLA) permissiveness of CB grafts has made it possible for more patients to undergo treatment. The drawback is that patients suffer from a longer period of compromised immunity.

Allergen provocation increases TH2-cytokines and FOXP3 expression in the asthmatic lung.

Background: Allergic asthma is caused by allergen-specific IgE and T-helper cell (Th) type 2 responses towards airborne allergens. The objective of this study was to investigate local and systemic regulatory mechanisms in the early asthmatic response to bronchial allergen provocation.

Methods: Birch pollen-allergic patients with mild asthma (n = 13) and healthy nonallergic controls (n = 14) were subjected to bronchoalveolar lavage (BAL) and blood sampling.

Prolonged antigen-exposure with carbohydrate particle based vaccination prevents allergic immune responses in sensitized mice.

Background: Defined particles carrying tightly bound allergens at high density have been suggested as alternatives in allergy vaccination. Carbohydrate based particles (CBP), sized 2 microm, provide a platform for covalent coupling of allergens.

Objective: To investigate the mechanisms of antigen presentation by CBP, as well as cellular and humoral responses after vaccination with the major cat allergen Fel d 1, covalently coupled to CBP.

Carbohydrate-based particles reduce allergic inflammation in a mouse model for cat allergy.

Background: Allergen-specific immunotherapy (ASIT) is the only treatment of allergic disease that gives long-lasting relief of symptoms. However, concerns for safety and efficiency have highlighted the need for improvement of the therapy. We have previously suggested carbohydrate-based particles (CBPs) as a novel adjuvant and allergen carrier for ASIT.

Low levels of endotoxin enhance allergen-stimulated proliferation and reduce the threshold for activation in human peripheral blood cells.

Background: Endotoxins, comprised of bacterial cell wall lipopolysaccharides (LPS), have been reported to have both protective and exacerbating effects on the development and maintenance of allergic disease in humans and on markers of allergic inflammation in animal models of allergy. In this study, we investigated the effect of low concentrations of LPS on human peripheral blood mononuclear cells (PBMC) stimulated with the major cat allergen Fel d 1.

Methods: Extensive purification of recombinant (r) Fel d 1 yielded essentially endotoxin-free rFel d 1 (0.

Immune regulation by CD4+CD25+ T cells and interleukin-10 in birch pollen-allergic patients and non-allergic controls.

Background: CD4+CD25+ regulatory T (Treg) cells and the cytokines IL-10 or TGF-beta play key roles in the maintenance of T cell homeostasis and tolerance to infectious and non-infectious antigens such as allergens.

Objective: To investigate the regulation of immune responses to birch pollen allergen compared with influenza antigen by Treg cells obtained from birch pollen-allergic patients and non-allergic controls.

Methods: Peripheral blood was collected from 10 birch pollen-allergic patients and 10 non-allergic healthy controls.

Structural characterization of the tetrameric form of the major cat allergen Fel d 1.

Felis domesticus allergen 1(Fel d 1) is a 35 kDa tetrameric glycoprotein formed by two heterodimers which elicits IgE responses in 95% of patients with allergy to cat. We have previously established in vitro conditions for the appropriate folding of recombinant Fel d 1 using a direct linkage of chain 1 to chain 2 (construct Fel d 1 (1+2)) and chain 2 to chain 1 (construct Fel d 1 (2+1)). Although the crystal structure of Fel d 1 (2+1) revealed a striking structural similarity to that of uteroglobin, a steroid-inducible cytokine-like molecule with anti-inflammatory and immunomodulatory properties, no functional tetrameric form of Fel d 1 could be identified.

Cytokine and antibody responses in birch-pollen-allergic patients treated with genetically modified derivatives of the major birch pollen allergen Bet v 1.

Background: Recently, recombinant hypoallergenic derivatives of the major birch pollen allergen, Bet v 1, were used to treat birch-pollen-allergic patients in a double-blind, placebo-controlled, multi-centre immunotherapy study. The aim of this study was to evaluate the effects of vaccination with aluminium-hydroxide-adsorbed recombinant Bet v 1 derivatives versus placebo on T-cell, cytokine and antibody responses in a subgroup of patients.

Methods: Blood was drawn from patients of the Swedish centre (n = 27; rBet v 1 fragments: n = 10; rBet v 1 trimer: n = 8, and placebo-aluminium hydroxide: n = 9) before the start and after completion of the treatment.

Immune responses in healthy and allergic individuals are characterized by a fine balance between allergen-specific T regulatory 1 and T helper 2 cells.

The mechanisms by which immune responses to nonpathogenic environmental antigens lead to either allergy or nonharmful immunity are unknown. Single allergen-specific T cells constitute a very small fraction of the whole CD4+ T cell repertoire and can be isolated from the peripheral blood of humans according to their cytokine profile. Freshly purified interferon-gamma-, interleukin (IL)-4-, and IL-10-producing allergen-specific CD4+ T cells display characteristics of T helper cell (Th)1-, Th2-, and T regulatory (Tr)1-like cells, respectively.
