Enzymes that affect glycoproteins of the human immune system, and thereby modulate defense responses, are abundant among bacterial pathogens. Two endoglycosidases from the human pathogen Streptococcus pyogenes, EndoS and EndoS2, have recently been shown to hydrolyze N-linked glycans of human IgG. However, detailed characterization and comparison of the hydrolyzing activities have not been performe

In the present study, two types of micro-pin–fin configurations were fabricated on silicon surfaces by a dry etching method, i.e., staggered pin fins (#1) and aligned pin fins with empty areas (#2). The micro-pin–fin surfaces were then further modified by depositing FeMn oxide nanoparticles (∼35 nm) electrostatically for 8 h and 16 h, respectively, namely #1-8h, #1-16h, #2-8h and #2-16h. Subcooled

By use of a batch microcalorimeter of the thermopile type, heat production was measured in isolated populations of human peripheral blood cells exposed to defined immune complexes formed in vitro. It was found that most of the heat production recorded in whole blood after admixture of immune complexes occurs in the granulocytes. Under these conditions small but constantly higher activation values

The hematopoietic stem cell (HSC) has and continues to be extensively investigated, and represents by far the most studied somatic stem cell. Development of various experimental technologies, including fluorescence activated cell sorting (FACS), have been crucial for research advancements within the hematopoietic field.

Platelets express Toll-like receptor 4 (TLR4), and this has been shown to be responsible for the thrombocytopenia induced by lipopolysaccharide (LPS) administration in vivo. We studied the role of LPS in mediating platelet phagocytosis by THP-1 cells in vitro by flow cytometry. Opsonization of platelets with an IgG monoclonal (W6/32) antibody or with IgG autoantibody-positive sera from patients wi

Background: 4-1BB (CD137) is a co-stimulatory receptor highly expressed on tumor reactive effector T cells and NK cells, which upon stimulation prolongs persistence of tumor reactive effector T and NK cells within the tumor and induces long-lived memory T cells. 4-1BB agonistic antibodies have been shown to induce strong anti-tumor effects that synergize with immune checkpoint inhibitors. The firs

Targeting the androgen receptor (AR) pathway prolongs survival in patients with prostate cancer, but resistance rapidly develops. Understanding this resistance is confounded by a lack of noninvasive means to assess AR activity in vivo. We report intracellular accumulation of a secreted antigen-targeted antibody (SATA) that can be used to characterize disease, guide therapy, and monitor response. A

Although the communication aspects of sport and football organizations are receiving in-creased scholarly attention, research from the perspective of fans of such organizations has mostly been neglected. This study problematizes the gap that exists be-tween the current social media communication of football organizations, that tend to be guided by commercial interests, and the expectation of fans

Suicide in children and young adults is a leading cause of premature mortality, and there is a need to develop a more profound understanding of the factors that contribute to these deaths. This study is part of the nationwide Retrospective Investigation of Health Care Utilization in Individuals who died by Suicide in Sweden 2015, conducted at Lund University, Sweden. The aim was to examine symptom

Introduction: Severe asthma is a heterogeneous condition characterized by distinct phenotypes and endotypes based on clinical or biological characteristics. Interleukin (IL) 4 and IL-13 are central cytokines in the type 2 (T2) immune response, crucial for T2 inflammation. Biologic therapies targeting the IL-4/IL-13 pathway, such as anti-IL-4Rα monoclonal antibodies (mAbs), have shown improvements
