Hermansky-Pudlak syndrome (HPS) encompasses disorders with abnormal function of lysosomes and lysosome-related organelles, and some patients who develop immunodeficiency. The basic mechanisms contributing to immune dysfunction in HPS are ill-defined. We analysed natural killer (NK) cells from patients diagnosed with HPS-1, HPS-2, HPS-4, and an unreported HPS subtype. NK cells from an HPS-2 and an unreported HPS subtype share a similar cellular phenotype with defective granule release and cytotoxicity, but differ in cytokine exocytosis...

Biopharmaceuticals, monoclonal antibody (mAb)-based therapeutics in particular, have positively impacted millions of lives. MAbs and related therapeutics are highly desirable from a biopharmaceutical perspective as they are highly target specific and well tolerated within the human system. Nevertheless, several mAbs have been discontinued or withdrawn based either on their inability to demonstrate efficacy and/or due to adverse effects. Approved monoclonal antibodies and derived therapeutics have been associated with adverse effects such as immunogenicity, cytokine release syndrome, progressive multifocal leukoencephalopathy, intravascular haemolysis, cardiac arrhythmias, abnormal liver function, gastrointestinal perforation, bronchospasm, intraocular inflammation, urticaria, nephritis, neuropathy, birth defects, fever and cough to name a few...

Carcinoembryonic antigen (CEA) is a cell surface antigen highly expressed in various cancer cell types and in healthy tissues. It has the potential to be a target for chimeric antigen receptor (CAR)-modified T-cell therapy; however, the safety of this approach in terms of on-target/off-tumor effects needs to be determined. To address this issue in a clinically relevant model, we used a mouse model in which the T cells expressing CEA-specific CAR were transferred into tumor-bearing CEA-transgenic (Tg) mice that physiologically expressed CEA as a self-antigen...

Cardiovascular diseases (CVD) are major causes of death and illness worldwide. In recent decades an increased prevalence of CVD mortality has been reported in low-medium income countries, which has been associated with changes in life styles, deficiencies in health systems and the persistence of social inequities.The metabolic syndrome comprises a cluster of cardiometabolic risk factors, with insulin resistance and increased adiposity as its central features. Identifying individuals with metabolic syndrome is important due to its association with an increased risk of coronary heart disease and type 2 diabetes mellitus (DM2)...

OBJECTIVES: To determine the role of S100A8/A9 in the pathogenesis of primary Sjögren's syndrome (pSS). METHODS: The serum levels of S100A8/A9 were determined in pSS patients and healthy controls by ELISA. The expression of S100A8/A9 in salivary glands was assessed by immunohistochemistry. The phenotype of S100A8+ and S100A9+ cells was identified using double immunofluorescence. The effects of S100A8/A9 on cytokine production by peripheral blood mononuclear cells (PBMCs) from pSS patients were determined in vitro by flow cytometry...

Chimeric antigen receptors (CARs) are engineered molecules that can be introduced into T cells to enable them to target specific tumor antigens. CAR T cells targeting CD19 have shown promise in patients with relapsed and refractory B-cell neoplasms, including those with acute lymphoblastic leukemia, chronic lymphocytic leukemia, and non-Hodgkin lymphomas. Notably, durable responses have been observed in patients who had not undergone consolidative stem cell transplant, a finding that correlates with reports of T-cell persistence and B-cell aplasia in studies of anti-CD19 treatment in vivo...

CLS involves sudden loss of intravascular fluids into the interstitial spaces. CLS was described as a possible complication after SCT. Few studies report the incidence of CLS in pediatric populations. We aimed to assess CLS incidence, its risk factors, and impact on the survival. The clinical charts of patients <18 years of age transplanted at our institution between 2002 and 2012 were reviewed. CLS was defined by weight gain >3% in 24 hours and positive intake balance despite furosemide administration...

The acute respiratory distress syndrome (ARDS) is a serious condition resulting from direct or indirect lung injury that is associated with high mortality and morbidity. A key biological event in the pathogenesis of the acute lung injury (ALI) that causes acute respiratory distress syndrome is activation of the lung endothelium cells (ECs), which is triggered by a variety of inflammatory insults leading to barrier disruption and excessive accumulation of neutrophils. Recently, we demonstrated that imatinib protects against lipopolysaccharide (LPS)-induced EC activation by inhibiting c-Abl kinase...

BACKGROUND: The acute respiratory distress syndrome (ARDS) is a complex pulmonary disorder in which the local release of cytokines and chemokines appears central to the pathophysiology. OBJECTIVE: Based on the known role of matrix metalloproteinase-3 (MMP3) in inflammatory processes, the objective was to examine the role of MMP3 in the pathogenesis of ARDS through the modulation of pulmonary inflammation. MATERIALS AND METHODS: Female and male, wild type (MMP3(+/+)) and knock out (MMP3(-/-)) mice were exposed to two, clinically relevant models of ARDS including (i) lipopolysaccharide (LPS)-induced lung injury, and (ii) hydrochloric acid-induced lung injury...

Croquemort, the homologue of human CD36, is a member of class B scavenger receptors, which is involved in bacteria phagocytosis and cytokins release. However, there is still less information about Croquemort in crustaceans. Here, a Croquemort from Pacific white shrimp Litopenaeus vannamei (LvCroquemort) and its truncated form (LvCroquemort-S1) cDNA sequences were identified, characterized and their role in bacteria clearance was investigated. The deduced protein of LvCroquemort is 533 amino acids and contains typical domains of CD36: the N-terminus and C-terminus in cytoplasm, two transmembrane regions and a large extracellular loop-like domain...

Men with post orgasmic illness syndrome (POIS) become ill rather immediately after ejaculation, whether spontaneously at night, during sexual intercourse or masturbation. Two subtypes are distinguished: primary and secondary POIS. It also occurs before or after a man has been sterilized. POIS is an invalidating most probably auto-immune disease leading to much distress in males and their partners. It is characterized by five criteria. Its symptoms are described by seven clusters. However, the manifestation of these symptoms varies from one male to the other but is relatively constant in the person himself...

It has been hypothesized that alterations in the composition of the gut microbiota might be associated with the onset of certain human pathologies, such as Alzheimer disease, a neurodegenerative syndrome associated with cerebral accumulation of amyloid-β fibrils. It has been shown that bacteria populating the gut microbiota can release significant amounts of amyloids and lipopolysaccharides, which might play a role in the modulation of signaling pathways and the production of proinflammatory cytokines related to the pathogenesis of Alzheimer disease...

OBJECTIVE: Initial success with chimeric antigen receptor-modified T cell therapy for relapsed/refractory acute lymphoblastic leukemia is leading to expanded use through multicenter trials. Cytokine release syndrome, the most severe toxicity, presents a novel critical illness syndrome with limited data regarding diagnosis, prognosis, and therapy. We sought to characterize the timing, severity, and intensive care management of cytokine release syndrome after chimeric antigen receptor-modified T cell therapy...

Systemic inflammatory response syndrome (SIRS) is a form of fatal acute inflammation for which there is no effective treatment. Here, we revealed that the ablation of Kelch domain containing 10 (KLHDC10), which we had originally identified as an activator of Apoptosis Signal-regulating Kinase 1 (ASK1), protects mice against TNFα-induced SIRS. The disease development of SIRS is mainly divided into two stages. The early stage is characterized by TNFα-induced systemic necroptosis, a regulated form of necrosis mediated by Receptor-interacting protein (RIP) 1/3 kinases...

Respiratory infection with Francisella tularensis (Ft) is characterized by a muted, acute host response, followed by sepsis-like syndrome that results in death. Infection with Ft establishes a principally anti-inflammatory environment that subverts host-cell death programs to facilitate pathogen replication. Although the role of cytokines has been explored extensively, the role of eicosanoids in tularemia pathogenesis is not fully understood. Given that lipoxin A4 (LXA4) has anti-inflammatory properties, we investigated whether this lipid mediator affects host responses manifested early during infection...

T cells can be genetically modified to target tumors through the expression of a chimeric antigen receptor (CAR). Most notably, CAR T cells have demonstrated clinical efficacy in hematologic malignancies with more modest responses when targeting solid tumors. However, CAR T cells also have the capacity to elicit expected and unexpected toxicities including: cytokine release syndrome, neurologic toxicity, "on target/off tumor" recognition, and anaphylaxis. Theoretical toxicities including clonal expansion secondary to insertional oncogenesis, graft versus host disease, and off-target antigen recognition have not been clinically evident...

CD19-specific chimeric antigen receptor (CAR)-modified T cells have antitumor activity in B cell malignancies, but factors that affect toxicity and efficacy have been difficult to define because of differences in lymphodepletion and heterogeneity of CAR-T cells administered to individual patients. We conducted a clinical trial in which CD19 CAR-T cells were manufactured from defined T cell subsets and administered in a 1:1 CD4(+)/CD8(+) ratio of CAR-T cells to 32 adults with relapsed and/or refractory B cell non-Hodgkin's lymphoma after cyclophosphamide (Cy)-based lymphodepletion chemotherapy with or without fludarabine (Flu)...
