N-linked glycosylation of the fragment crystallizable (Fc)-region of immunoglobulin G (IgG) is known to have a large influence on the activity of the antibody, an effect reported to be IgG subclass specific. This situation applies both to humans and mice. The mouse is often used as experimental animal model to study the effects of Fc-glycosylation on IgG effector functions, and results are not uncommonly translated back to the human situation. However, while human IgG Fc-glycosylation has been extensively characterized in both health and disease, this is not the case for mice...

Systemic high-dose interleukin-2 (IL-2) postconditioning has long been utilized in boosting the efficacy of T cells in adoptive cell therapy (ACT) of solid tumors. The resulting severe off-target toxicity of these regimens renders local production at the tumor an attractive concept with possible safety gains. We evaluated the efficacy and safety of intratumorally administered IL-2-coding adenoviruses in combination with tumor-infiltrating lymphocyte therapy in syngeneic Syrian hamsters bearing HapT1 pancreatic tumors and with T cell receptor transgenic ACT in B16...

BACKGROUND: We endeavored to develop clinically translatable non-human primate (NHP) models of severe poly-traumatic hemorrhagic shock. METHODS: NHPs were randomized into five pressure-targeted severe hemorrhagic shock (PTHS) ± additional injuries scenarios: 30-min PTHS (PTHS-30), 60-min PTHS (PTHS-60), PTHS-60 + soft tissue injury (PTHS-60+ST), PTHS-60+ST + femur fracture (PTHS-60+ST+FF) and decompensated PTHS+ST+FF (PTHS-D). Physiologic parameters were recorded and blood samples collected at five time points with animal observation through T = 24hrs...

Inherited mutations in Lipopolysaccharide Responsive Beige-like Anchor (LRBA) cause a recessive human immune dysregulation syndrome with memory B cell and antibody deficiency (common variable immunodeficiency, CVID), inflammatory bowel disease, enlarged spleen and lymph nodes, accumulation of activated T cells, and multiple autoimmune diseases. To understand the pathogenesis of the syndrome, C57BL/6 mice carrying a homozygous truncating mutation in Lrba were produced using CRISPR/Cas9-mediated gene targeting...

The p38 mitogen-activated protein kinase (MAPK) pathway is involved in the regulation of immune and inflammatory processes. We used p38α-conditional, p38β-deficient, and p38α/β double-null mouse models to address the role of these two p38 MAPK in CD4(+) T cells, and found that p38α deficiency causes these cells to hyperproliferate. Our studies indicate that both p38α and p38β are dispensable for T helper cell type 1 (Th1) differentiation but, by controlling IFNγ and TNFα production, are critical for normal Th1 effector function...

Malignant glioma is the most fatal of astrocytic lineage tumors despite therapeutic advances. Onset and progression of gliomas is accompanied by severe debilitation of T-cell defense and T-cell survival. One of the chief contributors to T-cell survival downstream of activation is the PI3K-AKT pathway. Our prior studies showed that the novel immunotherapeutic molecule T11-target structure (T11TS) blocks T-cell apoptosis in glioma. We also showed activation of immunological synapse components and calcineurin-NFAT pathway following T11TS immunotherapy of glioma-bearing rats...

Multiple sclerosis (MS) is a complex neurologic disorder that affects people with ever-changing needs. The MS health-care field has entered an era of exponential knowledge growth in which better understanding of the immunologic dysregulation of the disease has translated into an expanding array of treatment options. It is estimated that, if it has not already, within the next decade the demands of a growing MS patient population will outstrip the number of professionals dedicated to the management of this chronic, lifelong disease...

Germline heterozygous gain-of-function (GOF) mutations of NFKBIA, encoding IκBα, cause an autosomal dominant (AD) form of anhidrotic ectodermal dysplasia with immunodeficiency (EDA-ID). Fourteen unrelated patients have been reported since the identification of the first case in 2003. All mutations enhanced the inhibitory activity of IκBα, by preventing its phosphorylation on serine 32 or 36 and its subsequent degradation. The mutation certainly or probably occurred de novo in 13 patients, whereas it was inherited from a parent with somatic mosaicism in one patient...

There have been dramatic recent advances in understanding the basic pathophysiology and treatment strategies for multiple myeloma (MM). Research has shown both a high inter-patient diversity and intra-clonal heterogeneity even in a single patient in terms of cytogenetic/molecular abnormalities, and has also identified marked diversity in the immunological factors involved in tumor surveillance among MM patients. In the presence of a variety of novel agents, including molecular-targeted agents, immunomodulatory agents, and monoclonal antibodies, the optimal translation of current knowledge on both molecular and immunologic findings into clinical use is crucial for managing MM...

Given the sheer number of drugs (over 20!) available for treatment of seizures, epilepsy can be considered one of the most successful areas in pharmaceutical development and especially for neuroscience. However, despite the large number of drug treatment options available for managing patients with epilepsy, there remains considerable unmet need. For example, the overall impact on seizure control has not been substantial with approximately 30% of patients remaining refractory or their seizures not adequately controlled...

Immunoglobulin Y (IgY) is the predominant antibody found in hen's (Gallus domesticus) egg yolk. This antibody, developed against several microorganisms in hen egg yolk, has been successfully used as an alternative to immunoglobulins from mammals for use in immunodiagnostics and immunotherapy. Enteropathogenic Escherichia coli (E.coli) F4 is the main etiological agent associated with swine neonatal diarrhea, and it causes notable economic losses in swine production. The aim of the present study was to evaluate the relationship between humoral immune response and the activation of gut-associated lymphoid tissue (GALT) in laying hens intramuscularly immunized with E...

M Shankar-Hari
Sepsis results in complex alterations to the immune system. Our understanding of how these alterations in immune responses could help characterize extreme immune phenotypes, identify biomarkers with the ability to stratify patients for therapeutic interventions, surrogates in the causal pathway of clinical end-points, and treatable traits are still rudimentary. A methodologically rigorous, consensus-based approach should enrich sepsis immune subpopulations to increase the probability of successful trials.

Genetically caused neurological disorders of the central nervous system (CNS) are usually orphan diseases with poor or even fatal clinical outcome and few or no treatments that will improve longevity or at least quality of life. Neuroinflammation is common to many of these disorders, despite the fact that a plethora of distinct mutations and molecular changes underlie the disorders. In this article, data from corresponding animal models are analyzed to define the roles of innate and adaptive inflammation as modifiers and amplifiers of disease...

Stem cell-based therapy trials for the treatment of neurodegenerative diseases such as Parkinson's and Huntington's disease are being actively prepared both at the preclinical and clinical level. Preclinical validation of these stem cell transplantations necessitates to implement a translational continuum to take one pluripotent stem cell through the point of "first-in-man" clinical trial. Main steps along this translational continuum include stem cell GMP production, in vitro optimization of differentiation protocols necessary to direct stem cells to the desired neuronal phenotype, and evaluation of functional efficacy in animal models including large animal models...

Model animals naturally differ from humans in various respects and results from the former are not directly translatable to the latter. One approach to address this issue is humanized mice that are defined as mice engrafted with functional human cells or tissues. In humanized mice, we can investigate the development and function of human cells or tissues (including their products encoded by human genes) in the in vivo context of a small animal. As such, humanized mouse models have played important roles that cannot be substituted by other animal models in various areas of biomedical research...

Chronic cough in children is increasingly defined as a cough that lasts more than four weeks. It is recognized as a different entity than cough in adults. As a result, the diagnostic approach and management of chronic cough in children are no longer extrapolated from adult guidelines. These differences are attributed to the various characteristics of the respiratory tract, immunological system and nervous system in children. Specific paediatric guidelines and algorithms for chronic cough are now widely applied...

Klebsiella pneumoniae is a major human pathogen responsible for high morbidity and mortality rates. The emergence and spread of strains resistant to multiple antimicrobial agents and documented large nosocomial outbreaks are especially concerning. To develop new therapeutic strategies for K. pneumoniae, it is imperative to understand the population genomic structure of strains causing human infections. To address this knowledge gap, we sequenced the genomes of 1,777 extended-spectrum beta-lactamase-producing K...

Evidence of tumor-resident mature B cell and antibody compartments and reports of associations with favorable prognosis in malignant melanoma suggest that humoral immunity could participate in antitumor defense. Likely striving to confer immunological protection while being subjected to tumor-promoting immune tolerance, B cells may engender multiple functions, including antigen processing and presentation, cytokine-mediated signaling, antibody class switching, expression and secretion. We review key evidence in support of multifaceted immunological mechanisms by which B cells may counter or contribute to malignant melanoma, and we discuss their potential translational implications...

Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disease with various underlying pathophysiologic mechanisms which translate to endotypes, in contrast to clinical phenotypes or histological subtypes. Defining endotypes can help clinicians predict disease prognosis, select subjects suitable for a specific therapy, and assess risks for comorbid conditions, including asthma. Therefore, with recent advancement of biologicals in CRS clinical trials, endotyping can be a breakthrough in treating recalcitrant CRS...
