Outcomes from a mechanistic biomarker multi-arm and randomised study of liposomal MTP-PE (Mifamurtide) in metastatic and/or recurrent osteosarcoma (EuroSarc-Memos trial).

The phase III clinical study of adjuvant liposomal muramyl tripeptide (MTP-PE) in resected high-grade osteosarcoma (OS) documented positive results that have been translated into regulatory approval, supporting initial promise for innate immune therapies in OS. There remains, however, no new approved treatment such as MTP-PE for either metastatic or recurrent OS. Whilst the addition of different agents, including liposomal MTP-PE, to surgery for metastatic or recurrent high-grade osteosarcoma has tried to improve response rates, a mechanistic hiatus exists in terms of a detailed understanding the therapeutic strategies required in advanced disease.

Study of Peri-Articular Anaesthetic for Replacement of the Knee (SPAARK): study protocol for a patient-blinded, randomised controlled superiority trial of liposomal bupivacaine.

Background: Optimising the management of peri-operative pain and recovery following knee replacement has been identified as a patient priority. Current pain relief strategies use opiate-based analgesia; however, up to 50% of patients experience significant side effects. Local anaesthetic incisional infiltration is one alternative.

An anti-TL1A antibody for the treatment of asthma and inflammatory bowel disease.

TL1A is an attractive therapeutic target for the treatment of mucosal inflammation associated with inflammatory bowel disease (IBD) and asthma. Blockade of the TL1A pathway has been shown to reduce inflammatory responses while leaving baseline immunity intact, and to be beneficial in animal models of colitis and asthma. Given the therapeutic potential of blocking this pathway in IBD and asthma, we developed C03V, a human antibody that binds with high affinity to soluble and membrane-bound TL1A.

Potent neutralizing anti-CD1d antibody reduces lung cytokine release in primate asthma model.

CD1d is a receptor on antigen-presenting cells involved in triggering cell populations, particularly natural killer T (NKT) cells, to release high levels of cytokines. NKT cells are implicated in asthma pathology and blockade of the CD1d/NKT cell pathway may have therapeutic potential. We developed a potent anti-human CD1d antibody (NIB.

A novel class of anti-IL-12p40 antibodies: potent neutralization via inhibition of IL-12-IL-12Rβ2 and IL-23-IL-23R.

While current therapeutic antibodies bind to IL-12 and IL-23 and inhibit their binding to IL-12Rβ1, we describe a novel antibody, termed 6F6, that binds to IL-12 and IL-23 and inhibits the interaction of IL-12 and IL-23 with their cognate signalling receptors IL-12Rβ2 and IL23R. This antibody does not affect the natural inhibition of the IL-12/23 pathway by the antagonists monomeric IL-12p40 and IL-12p80, which suggests that a dual antagonist system is possible. We have mapped the epitope of 6F6 to domain 3 of the p40 chain common to IL-12 and IL-23 and demonstrate that an antibody bound to this epitope is sufficient to inhibit engagement of the signalling receptors.

Key role of the GITR/GITRLigand pathway in the development of murine autoimmune diabetes: a potential therapeutic target.

Background: The cross-talk between pathogenic T lymphocytes and regulatory T cells (Tregs) plays a major role in the progression of autoimmune diseases. Our objective is to identify molecules and/or pathways involved in this interaction and representing potential targets for innovative therapies. Glucocorticoid-induced tumor necrosis factor receptor (GITR) and its ligand are key players in the T effector/Treg interaction.

Allelic variation of Ets1 does not contribute to NK and NKT cell deficiencies in type 1 diabetes susceptible NOD mice.

The NOD mouse is a well characterized model of type 1 diabetes that shares several of the characteristics of Ets1-deficient targeted mutant mice, viz: defects in TCR allelic exclusion, susceptibility to a lupus like disease characterized by IgM and IgG autoantibodies and immune complex-mediated glomerulonephritis, and deficiencies of NK and NKT cells. Here, we sought evidence for allelic variation of Ets1 in mice contributing to the NK and NKT cell phenotypes of the NOD strain. ETS1 expression in NK and NKT cells was reduced in NOD mice, compared to C57BL/6 mice.

A novel role for Glucocorticoid-Induced TNF Receptor Ligand (Gitrl) in early embryonic zebrafish development.

Tumour necrosis factor ligand and receptor superfamily (TNFSF and TNFRSF) members have diverse and well-studied functions in the immune system. Additional, non-immunological roles, such as in the morphogenesis of bone, tooth, hair and skin have also been described for some members. GITRL and its receptor GITR are well-described as co-regulators of the mammalian immune response.

Attachment and selective attention: disorganization and emotional Stroop reaction time.

Although central to attachment theory, internal working models remain a useful heuristic in need of concretization. We compared the selective attention of organized and disorganized mothers using the emotional Stroop task. Both disorganized attachment and emotional Stroop response involve the coordination of strongly conflicting motivations under conditions of emotional arousal.

On the relation between maternal state of mind and sensitivity in the prediction of infant attachment security.

Attachment theorists assume that maternal mental representations influence responsivity, which influences infant attachment security. However, primary studies do not support this mediation model. The authors tested mediation using 2 mother-infant samples and found no evidence of mediation.

Clinical application of NKT cell assays to the prediction of type 1 diabetes.

Type 1 diabetes is a disease characterised by disturbed glucose homeostasis, which results from autoimmune destruction of the insulin-producing beta cells in the pancreas. The autoimmune attack, while not yet fully characterised, exhibits components of both mis-targeting and failed tolerance induction. The involvement of non-classical lymphocytes in the induction and maintenance of peripheral tolerance has recently been recognised and natural killer T (NKT) cells appear to play such a role.

Errorless compliance training with physically abusive mothers: a single-case approach.

Objective: "Errorless compliance training" is a recently developed, success-based approach for teaching children to comply with parental requests without the use of coercive consequences. Two mothers were trained to use this intervention to reduce severe child defiance that was precipitating mother/child confrontations and physical abuse.

Method: To determine probability of child compliance to specific requests, we observed mothers delivering requests to their child.

CD1d-restricted NKT cells: an interstrain comparison.

CD1d-restricted Valpha14-Jalpha281 invariant alphabetaTCR(+) (NKT) cells are well defined in the C57BL/6 mouse strain, but they remain poorly characterized in non-NK1.1-expressing strains. Surrogate markers for NKT cells such as alphabetaTCR(+)CD4(-)CD8(-) and DX5(+)CD3(+) have been used in many studies, although their effectiveness in defining this lineage remains to be verified.

Cytometric and functional analyses of NK and NKT cell deficiencies in NOD mice.

Defects in NK and NKT cell activities have been implicated in the etiology of type 1 (autoimmune) diabetes in NOD mice on the basis of experiments performed using surrogate phenotypes for the identification of these lymphocyte subsets. Here, we have generated a congenic line of NOD mice (NOD.b-Nkrp1(b)) which express the allelic NK1.

NKT cells: facts, functions and fallacies.

The proposed roles of NK1.1(+) T (NKT) cells in immune responses range from suppression of autoimmunity to tumor rejection. Heterogeneity of these cells contributes to the controversy surrounding their development and function.

Success-based, noncoercive treatment of oppositional behavior in children from violent homes.

Objectives: Errorless compliance training is a success-based, noncoercive intervention for children with severe oppositional behavior. The strategy involves hierarchical introduction of more demanding parental requests at a gradual pace that greatly reduces noncompliance and obviates the need for constraining consequences (e.g.

Linkage analysis of systemic lupus erythematosus induced in diabetes-prone nonobese diabetic mice by Mycobacterium bovis.

Systemic lupus erythematosus induced by Mycobacterium bovis in diabetes-prone nonobese diabetic mice was mapped in a backcross to the BALB/c strain. The subphenotypes-hemolytic anemia, antinuclear autoantibodies, and glomerular immune complex deposition-did not cosegregate, and linkage analysis for each trait was performed independently. Hemolytic anemia mapped to two loci: Bah1 at the MHC on chromosome 17 and Bah2 on distal chromosome 16.

Lack of consistency in research papers over the definition of pre-eclampsia.

The most common definition of pre-eclampsia involves hypertension and proteinuria. This has changed little in over a hundred years despite advances in understanding the underlying pathological process. However, a number of variations in definition exist, and this paper demonstrates a lack of consistency in research articles in defining pre-eclampsia.

Multiple deficiencies underlie NK cell inactivity in lymphotoxin-alpha gene-targeted mice.

We have evaluated the NK cell antitumor activity in lymphotoxin (LT)-deficient mice. Both NK cell-mediated tumor rejection and protection from experimental metastases were significantly compromised in LT-alpha-deficient mice. Analysis of LT-alpha-deficient mice revealed that the absolute number of alphabetaTCR- NK1.
