The brain has long been considered an immunologically privileged site, and the role of immunotherapy in treating intracranial disease has only recently been revived-with preclinical evidence showing that the systemic immune system responds to immunotherapy for intracranial disease, and with clinical evidence demonstrating improved locoregional control and survival compared with historical outcomes when immune-directed therapies are combined with radiation. Pharmaceutical industry-supported multi-institutional drug efficacy studies routinely exclude patients with brain metastases, so current evidence for treatment of brain metastases using stereotactic radiosurgery combined with immunotherapy comes from single-institution studies...

Application of single-cell genomics technologies has revolutionized our approach to study the immune system. Unravelling the functional diversity of immune cells and their coordinated response is key to understanding immunity. Single-cell transcriptomics technologies provide high-dimensional assessment of the transcriptional states of immune cells and have been successfully applied to discover new immune cell types, reveal haematopoietic lineages, identify gene modules dictating immune responses and investigate lymphocyte antigen receptor diversity...

Phosphorylcholine (PC) is an epitope on oxidized low-density lipoprotein (oxLDL), apoptotic cells and several pathogens like Streptococcus pneumoniae. Immunoglobulin M against PC (IgM anti-PC) has the ability to inhibit uptake of oxLDL by macrophages and increase clearance of apoptotic cells. From our genome-wide association studies (GWAS) in four European-ancestry cohorts, six SNPs in 11q24.1 were discovered (in 3002 individuals) and replicated (in 646 individuals) to be associated with serum level of IgM anti-PC (the leading SNP rs35923643-G, combined beta=0...

INTRODUCTION: Rectal prolapse (RP) is related to an increase of intra-abdominal pressure, pelvic floor disease or anal sphincter. The most common causes of RP are constipation, cystic fibrosis, whooping cough and dysenteric diarrhea. However, celiac disease is not considered among the pathologies re lated to RP. OBJECTIVE: To present a scarcely described association between RP and celiac disease. CLINICAL CASES: We presented 2 preschoolers in whom the reason for consultation was RP, whose study was focused on as prolonged diarrhea, due to the antecedent of pasty consistency of stools...

Bisphosphonates are formidable inhibitors of osteoclast-mediated bone resorption employed for therapy of multiple myeloma (MM) subjects with osteolytic lesions. Osteonecrosis of the jaw (ONJ) is an uncommon drug-induced adverse event of these agents. MicroRNAs (miRNAs) are a group of small, noncoding RNAs nucleotides, which are essential post-transcriptional controllers of gene expression. They have a central role in the normal bone development. The goal of our study was to investigate 18 miRNAs, whose targets were previously validated and described in MM subjects without ONJ, in peripheral lymphocytes of MM subjects with bisphosphonate-induced ONJ...

Modern cancer immunotherapies represent a major shift in paradigm with respect to how we understand innate and adaptive responses to malignancy. Successful tumors co-opt normal immunosurveillance mechanisms by potent interactions between the tumor and local draining lymph nodes. Tumor cells mediate a complex and dynamic immunoediting procedure that results in increased vascular efflux into the draining lymphatics, an immunosuppressive microenvironment rich in regulatory T-lymphocytes, dysfunctional antigen presentation, and downregulation of normal effector lymphocyte responses...

Background: A 10% cocoa-enriched diet influences immune system functionality including the prevention of the antibody response and the induction of lower immunoglobulin (Ig) concentrations. However, neither cocoa polyphenols nor cocoa fiber can totally explain these immunoregulatory properties. Objectives: This study aimed to establish the influence of cocoa theobromine in systemic and intestinal Ig concentrations and to determine the effect of cocoa or theobromine feeding on lymphoid tissue lymphocyte composition...

Acquired angioedema due to C1 inhibitor deficiency (C1INH-AAE) is a rare and potentially fatal syndrome of bradykinin-mediated angioedema characterized by episodes of angioedema without urticaria. It typically manifests with nonpitting edema of the skin and edema in the gastrointestinal (GI) tract mucosa or upper airway. Edema of the upper airway and tongue may lead to life-threatening asphyxiation. C1INH-AAE is typically under-diagnosed because of its rarity and its propensity to mimic more common abdominal conditions and allergic reactions...
