INTRODUCTION: While seasonal influenza vaccination is recommended for individuals with asthma, uptake in this population is low. We examined how self-rated health impacts reasons for not being immunized against influenza in Canadian adults with asthma, focusing on those who have never been immunized. METHODS: We pooled four cycles of the Canadian Community Health Survey (cycles 3.1(2005), 2007/08, 2009/10 and 2011/12), grouping individuals by whether their reasons for not having been vaccinated were perceptual or technical...

Autoantigen-specific immunological tolerance represents a central objective for prevention of type 1 diabetes (T1D). Previous studies demonstrated mucosal antigen administration results in expansion of Foxp3(+) and LAP(+) regulatory T cells (Tregs), suggesting oral delivery of self-antigens might represent an effective means for modulating autoimmune disease. Early preclinical experiments using the non-obese diabetic (NOD) mouse model reported mucosal administration of T1D-related autoantigens [proinsulin or glutamic acid decarboxylase 65 (GAD)] delayed T1D onset, but published data are conflicting regarding dose, treatment duration, requirement for combinatorial agents, and extent of efficacy...

Accumulation of the interferon-stimulated gene (ISG) 15 protein product, which is reversibly conjugated to numerous polypeptide targets, impacts the proteome and physiology of uninfected and infected cells. While many viruses, including human cytomegalovirus (HCMV) blunt host antiviral defenses by limiting ISG expression, the overall abundance of ISG15 monomer and protein conjugates rises in HCMV-infected cells. However, the molecular signals underlying ISG15 accumulation and whether the ISG15 polypeptide itself influences HCMV infection biology remain unknown...

HIV-1 envelope glycoprotein (Env) glycosylation is important because individual glycans are components of multiple broadly neutralizing antibody epitopes, while shielding other sites that might otherwise be immunogenic. The glycosylation on Env is influenced by a variety of factors, including the genotype of the protein, the cell line used for its expression, and the details of the construct design. Here, we used a mass spectrometry-based approach to map the complete glycosylation profile at every site in multiple HIV-1 Env trimers, accomplishing two goals: 1) We determined which glycosylation sites contain conserved glycan profiles across many trimeric Envs...

BACKGROUND: Understanding of humoral immune responses in tuberculosis (TB) is gaining interest, since B cells and antibodies may be important in diagnosis as well as protective immune responses. High-content peptide microarrays (HCPM) are highly precise and reliable for gauging specific antibody responses to pathogens, as well as autoantigens. METHODS: We used a HCPM comprising epitopes spanning 154 proteins of Mycobacterium tuberculosis (M. tb) to gauge specific IgG antibody responses in sera of TB patients from Africa and South America...

INTRODUCTION: In Australia, influenza vaccination is recommended for all women who will be pregnant during the influenza season. Vaccine safety and effectiveness are key concerns and influencers of uptake for both vaccine providers and families. We assessed the safety of receiving an influenza vaccination during any trimester of pregnancy with respect to preterm births and infant birthweight. METHODS: We conducted a nested retrospective cohort study of 'FluMum' participants (2012-2014)...

1.Tuberculosis (TB) is an important and widespread disease of wildlife, livestock, and humans worldwide, but long-term empirical datasets describing this condition are rare. A population of meerkats (Suricata suricatta) in South Africa's Kalahari Desert have been diagnosed with Mycobacterium suricattae, a novel strain of TB, causing fatal disease in this group-living species. 2.This study aimed to find characteristics associated with clinical TB in meerkats. These characteristics could subsequently be used to identify "at risk" animals within a population, and target these individuals for control measures...

Investigating whether high-risk human papillomavirus (HR-HPV) types tend to become grouped in a particular way and whether factors are associated with such grouping is important for measuring the real impact of vaccination. In total, 219 women proving positive for HPV as detected by real-time PCR were included in the study. Each sample was analysed for detecting and quantifying six viral types and the hydroxymethylbilane synthase gene. Multiple correspondence analysis led to determining grouping patterns for six HR-HPV types and simultaneous association with multiple variables and whether viral load was related to the coexistence of other viral types...

OBJECTIVE: Cervical carcinoma (CC) is the second cause of death among women aged 15 and 44 in Spain. CC is linked to hig-risk human papillomavirus (HR-HPV) infection and its prevalence varies according age and geographical region. The awereness of the latter is essential for public health prevention efforts. The aim was to study the age related in HR-HPV genotypes in cytologies with squamous intraepithelial lesion (SIL). METHODS: From a total of 67,935 ginecologic cytologies over a four-year period, we selected cytologic specimens with SIL...

Natural killer (NK) cells are a diverse population of lymphocytes with a range of biological roles including essential immune functions. NK cell diversity is in part created by the differential expression of cell surface receptors which modulate activation and function, including multiple subfamilies of C-type lectin receptors encoded within the NK complex (NKC). Little is known about the gene content of the NKC beyond rodent and primate lineages, other than it appears to be extremely variable between mammalian groups...

A major barrier to an Human Immunodeficiency Virus Type 1 (HIV) infection cure is the establishment of a viral reservoir despite cART. It is unclear how HIV-specific CTLs influence the size of the reservoir in early HIV infection. 28 subjects with early HIV infection were recruited to receive cART and followed for 48 weeks. HIV reservoirs in peripheral CD4+ T cells measured by cell associated proviral DNA and viral outgrowth cultures were determined at baseline and 48 weeks of cART. At baseline, Granzyme B and IFN-γ ELISpot assays were performed with peptides spanning the HIV proteome...

Betanodavirus, also referred to nervous necrosis virus (NNV), is the causative agent of the fatal disease, viral nervous necrosis and has brought significant economic losses in marine and freshwater cultured fish, especially larvae and juveniles. Here, we used an established invasion model with virus-like particle (VLP)-cells, mimicking orange-spotted grouper nervous necrosis virus (OGNNV), to investigate the crucial events of virus entry. VLP were observed in the perinuclear regions of Asian sea bass (SB) cells within 1...

BACKGROUND: Immunizations are one of the most important health interventions of the 20th century, yet people in many areas of the world do not receive adequate immunizations. Approximately 3 million people worldwide die every year from vaccine-preventable diseases; about half of these deaths are young children and infants. Global travel is more common; diseases that were once localized now can be found in communities around the world. PROBLEM: Multiple barriers to immunizations have been identified...

BACKGROUND: Childhood vaccination is an effective way to prevent serious childhood illnesses, but many children do not receive all the recommended vaccines. There are various reasons for this; some parents lack access because of poor quality health services, long distances or lack of money. Other parents may not trust vaccines or the healthcare workers who provide them, or they may not see the need for vaccination due to a lack of information or misinformation about how vaccinations work and the diseases they can prevent...

Maternal vaccination represents a potential strategy to protect both the mother and the offspring against life threatening infections. This protective role has mainly been associated with antibodies but the role of cell mediated immunity in particular passively transferred cytokines is not well understood. Herein, using a pertussis model we have demonstrated that immunization of pregnant sows with heat-inactivated bacteria leads to induction of a wide range of cytokines (e.g. TNF-α, IFN-γ, IL-6, IL-8 and IL-12/IL-23p40) in addition to pertussis-specific antibodies...

The adolescent period heralds the pediatric patient's transition into adulthood. It is a time of dynamic development during which effective preventive care measures can promote safe behaviors and the development of lifelong health habits. One of the foundations of preventive adolescent health care is timely vaccination, and every visit can be viewed as an opportunity to update and complete an adolescent's immunizations.In the past decade, the adolescent immunization schedule has expanded to include 2 doses of quadrivalent meningococcal conjugate vaccine, 1 dose of tetanus, diphtheria, acellular pertussis, absorbed vaccine, 2 or 3 doses of human papillomavirus vaccine, depending on the child's age, and an annual influenza vaccine...

: Social modeling is a process by which pain behaviours are learned, and research has found parents act as models for their children's behaviour. Despite social learning theory predicting that same-sex models have greater impact, no experimental investigation to date has examined the role of sex of the model or observer in social learning of pediatric pain. The present study recruited 168 parent-child dyads (equal father-son, father-daughter, mother-son, and mother-daughter dyads) where children were generally healthy 6- to 8-year-olds...

BACKGROUND: Bacille Calmette-Guérin (BCG) is the world's most widely distributed vaccine, used against tuberculosis (TB), in cancer immunotherapy and in autoimmune diseases due to its immunomodulatory properties. Up to now, the effect of BCG vaccination on antibody responses to host proteins has not been reported. High-content peptide microarrays (HCPM) offer a unique opportunity to gauge specific humoral immune responses. METHODS: We tested sera of BCG-vaccinated healthy adults on a human HCPM platform (4953 randomly selected epitopes of human proteins) to detect specific immunoglobulin gamma (IgG) responses...
