B cells play a critical role in the immune response by producing antibodies, which display remarkable diversity. Here we describe a bioinformatic pipeline, BALDR (BCR Assignment of Lineage using De novo Reconstruction) that accurately reconstructs the paired heavy and light chain immunoglobulin gene sequences from Illumina single-cell RNA-seq data. BALDR was accurate for clonotype identification in human and rhesus macaque influenza vaccine and simian immunodeficiency virus vaccine induced vaccine-induced plasmablasts and naïve and antigen-specific memory B cells...

Healthcare workers (HCWs) at an Australian cancer centre were evaluated using a voluntary declination form program to determine factors contributing to declination of annual influenza vaccination. Overall, 1835/2041 HCWs (89.9%) completed a consent or declination form; 1783 were vaccinated and 52 declined. Staff roles with minimal patient contact were significantly associated with lower vaccine uptake (adjusted odds ratio 0.48, 95% confidence interval 0.23-0.99). Reasons for vaccine refusal included personal choice (41%), previous side-effect/s (23...

The widely used influenza subunit vaccine would benefit from increased protection rates in vulnerable populations. Skin immunization by microneedle (MN) patch can increase vaccine immunogenicity, as well as increase vaccination coverage due to simplified administration. To further increase immunogenicity, we used granulocyte-macrophage colony stimulating factor (GM-CSF), an immunomodulatory cytokine already approved for skin cancer therapy and cancer support treatment. GM-CSF has been shown to be upregulated in skin following MN insertion...

BACKGROUND: This is an update of the Cochrane review published in 2013, Issue 10.Immunosuppressed cancer patients are at increased risk of serious influenza-related complications. Guidelines, therefore, recommend influenza vaccination for these patients. However, data on vaccine effectiveness in this population are lacking, and the value of vaccination in this population remains unclear. OBJECTIVES: To assess the effectiveness of influenza vaccine in immunosuppressed adults with malignancies...

Ephedrine alkaloids-free Ephedra Herb extract (EFE) has been developed to eliminate the adverse effects caused by ephedrine alkaloid-induced sympathetic hyperactivation. Previously, we reported that EFE possesses analgesic, anti-influenza, and cancer metastatic inhibitory effects at comparable levels to that of Ephedra Herb extract (EHE). However, it has not yet been demonstrated that EFE is free from the known side effects of EHE, such as excitation, insomnia, and arrhythmias. In this study, the incidence of these adverse effects was compared between mice administered EHE and those administered EFE...

Due to the tumor malignancy or immunosuppressive treatment, patients with cancer in general are more susceptible to vaccine-preventable infections. The types, timing, dose of vaccination or even the immunization program for them may differ from those for the normal persons. At present, it is recommended to use inactivated vaccines for patients with cancer rather than attenuated live vaccines, Vaccinations should be avoided during immunosuppressive therapy; patients with cancer should receive double dosage of hepatitis B vaccines and two doses of inactivated influenza vaccines yearly...

Human adenovirus type 4 (HAdV-4) is most commonly isolated in military settings. We conducted detailed molecular characterization on 36 HAdV-4 isolates recovered from civilian adults with acute respiratory disease (ARD) in the northeastern United States during 2011-2015. Specimens came from college students, residents of long-term care facilities or nursing homes, a cancer patient, and young adults without co-morbidities. HAdV-4 genome types 4a1 and 4a2, the variants most frequently detected among US military recruits in basic training before the restoration of vaccination protocols, were isolated in most cases...

Influenza A virus (IAV) has shown promise as an oncolytic agent. To improve IAV as an oncolytic virus, we sought to design a transgenic virus expressing an immune checkpoint-inhibiting antibody during the viral life cycle. To test whether it was possible to express an antibody during infection, an influenza virus was constructed encoding the heavy chain of an antibody on the PB1 segment and the light chain of an antibody on the PA segment. This antibody-expressing IAV grows to high titers, and the antibodies secreted from infected cells exhibit comparable functionality with hybridoma-produced antibodies...

We studied the epidemiology of Haemophilus influenzae type b (Hib) infections among children with cancer admitted to Canadian pediatric hospitals. From 1991-2014, 13 cases among children with cancer were identified through active surveillance. Average age was 6.7 years. Six of 7 cases eligible for infant immunization were age-appropriately immunized (vaccine failures). Children with cancer may benefit from booster Hib immunization.

Sialidase releases sialic acid residues from the ends of sugar chains. The sialidases are involved in many physiological processes including cell differentiation and proliferation and immune function as well as pathophysiological conditions such as various human cancers and infections. Therefore visualization of sialidase activities with high sensitivity could provide valuable insights into these isozyme's activity. We developed novel fluorescent sialidase substrates, 2-benzothiazol-2-yl-phenol derivatives-based N-acetylneuraminic acid (Neu5Ac) (BTP-Neu5Ac) substrates, for highly sensitive and specific visualization of sialidase activity in living mammalian tissues and virus-infected cells...

The inflammatory tumoral-immune response alters the physiology of the tumor microenvironment, which may attenuate genomic instability. In addition to inducing inflammatory immune responses, several pathogenic bacteria produce genotoxins. However the extent of microbial contribution to the tumor microenvironment biology remains unknown. We utilized The Cancer Genome Atlas, (TCGA) breast cancer data to perform a novel experiment utilizing unmapped and mapped RNA sequencing read evidence to minimize laboratory costs and effort...
