SDY2312: Molecular signatures in a Hepatitis B Vaccine-immunized neonatal Tissue Construct in vitro correlate with antibody response in vivo | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Status: | New | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Description: | Only three licensed vaccines are currently approved for neonatal use worldwide with recommended administration around the time of birth: Hepatitis B Vaccine (HBV), Oral Poliovirus Vaccine (OPV) and the Bacille Calmette-Guérin (BCG) tuberculosis vaccine. We have previously shown that baseline (pre-vaccination) and early vaccine-induced systemic changes in global molecular patterns- i.e., “OMIC” signatures -in the days immediately post-immunization can predict subsequent protective humoral and cellular immune responses. However, it is unclear how the exact timing and sequence of neonatal vaccination can affect signatures of immunogenicity and vaccine-induced protection in humans. Herein, we employ our 3-dimensional tissue construct model that was previously used to investigate and replicate human age- specific vaccine responses in vivo, to a) gain insights into vaccine-induced OMIC signatures after single vs combined vaccination and b) investigate the association between human in vitro OMIC signatures and human in vivo hepatitis B antibody titers, a universally-accepted correlate of vaccine-induced protection, from the same study participants. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

SDY2584: Systems Biology to Identify Biomarkers of Neonatal Vaccine Immunogenicity - Papua New Guinea (PNG) Validation cohort | |||||||||||||||||||||||||
Status: | New | ||||||||||||||||||||||||
Description: | Infection is the most common cause of death in early life, especially for newborns and can be reduced by immunization but insufficient knowledge of how vaccines protect the very young limits their optimal use. To gain insight into how vaccines induce protection of the most vulnerable, our project employs two novel approaches studying newborn responses to hepatitis B vaccine (HBV): (a) systems biology that uses technologies which comprehensively measure global changes in molecules such as transcriptomics (RNA) and proteomics (proteins), as well as cell composition of the blood and (b) use of human newborn blood components, collected prior to immunization, to model vaccine responses in vitro (outside the body). Characterizing vaccine-induced molecular patterns (signatures) that correspond to vaccine-mediated protection will accelerate development and optimization of vaccines against early life infections of major global health importance. | ||||||||||||||||||||||||

SDY2869: Maintenance of protective immunity to COVID-19 vaccines in multiple sclerosis patients on B cell-depleting therapy | |||||||
Status: | New | ||||||
Description: | Immune-mediated protection generated to COVID-19 mRNA vaccines is correlated to the presence of anti-Spike protein neutralizing antibodies. B cell depleting (BCD) therapies used to treat multiple sclerosis (MS), diminish this humoral response, though T cell-mediated immunity can be generated. To study the long-term persistence of these differential responses, the effects of different types and modes of immune modulators, and the resultant effects of protection in patients with MS, we evaluated the humoral and cellular response to COVID-19 vaccines in patients with MS from four centers, ranging from one to 70 weeks post-vaccination. BCD therapies in patients with MS significantly reduced the antibody response and enhanced the cellular response to COVID-19 vaccination, with some variations among different anti-CD20 drugs. Despite these alterations persisting for many months following vaccination, the patients retained protective immunity. These results highlight the critical role of T cell-mediated immunity in anti-viral protection independent of humoral immunity. | ||||||

SDY3083: Airway T cell Dynamics in Children with Treatment-Refractory Recurrent Wheeze | |||||||
Status: | New | ||||||
Description: | Severe asthma in children is notoriously difficult to treat, and its immunopathogenesis is complex. In particular, the contribution of T cells and relationships to antiviral immunity remain enigmatic. Here, we coupled deep phenotyping with machine learning methods to elucidate the dynamics of T cells in the lower airways of children with treatment-refractory recurrent wheeze, and examine rhinovirus (RV) as a driver. Our strategy revealed a T cell landscape dominated by type 1 and type 17 CD8+ signatures. Interrogation of phenotypic relationships coupled with trajectory mapping identified T cell migratory and differentiation pathways spanning the blood and airways that culminated in tissue residency, and involved transitions between type 1 and type 17 tissue-resident types. These dynamics were reflected in cytokine polyfunctionality. Use of machine learning tools to cross-compare T cell populations that were enriched in the airways of RV-positive children with those induced in the blood following experimental RV challenge precisely pinpointed RV-responsive signatures that contributed to T cell migratory and differentiation pathways. Despite their rarity, these signatures were also detected in the airways of RV-negative children. Together, our results underscore the aberrant nature of type 1 immunity in the airways of children with recurrent wheeze, and implicate an important viral trigger as a driver. | ||||||

SDY1644: Urban Environmental Factors and Childhood Asthma (URECA) (ICAC-07) | ||||||||||||||||||||||||||||
Status: | Updated | |||||||||||||||||||||||||||
Description: | The purpose of this study is to determine the way environmental factors (like the components of inner-city household dust) affect immune system development and symptoms of asthma in inner city children. The study is divided into three periods, as the subjects age from birth to 10 years old. Each age bracket will explore different objectives and endpoints. Study Objectives/Hypotheses: Subjects age 0 to 3 years old: Environmental factors in the inner city adversely influence the development of the immune system to promote cytokine dysregulation, allergy, and recurrent wheezing by age 3. Children who have had a viral lower respiratory infection and have developed cytokine dysregulation by age 3 are at increased risk for the development of asthma by age 6. Subjects age 4 to 7 years old: There is a unique pattern of immune development that is driven by specific urban exposures in early life, and this pattern of immune development is characterized by: 1) impairment of antiviral responses and 2) accentuation of Th2-like responses (e.g. cockroach-specific Interleukin-13(IL-13)). The clinical effects of these changes in immune development are frequent virus-induced wheezing and allergic sensitization by 3-4 years of age, and these characteristics synergistically increase the risk of asthma at age 7 years. Subjects age 7 to 10 years old: There are unique combinations of environmental exposures (cockroach allergens, indoor pollutants [Environmental Tobacco Smoke (ETS) and Nitrogen Dioxide (NO2)], lack of microbial exposure), and family characteristics (stress, genetic factors related to innate immunity) that synergistically promote asthma onset, persistence, and morbidity in urban neighborhoods. These exposures and characteristics influence immune expression and lung development during critical periods of growth, resulting in specific asthma phenotypes. Subjects age 10 to 16 years old: To determine the wheezing, asthma and atopy phenotypes in minority children growing up in poor urban neighborhoods as they develop from birth through adolescence. | |||||||||||||||||||||||||||

SDY2903: High-throughput single-cell profiling of B cell responses following inactivated influenza vaccination in young and older adults | |||||||
Status: | Updated | ||||||
Description: | Seasonal influenza contributes to a substantial disease burden, resulting in approximately 10 million hospital visits and 50 thousand deaths in a typical year in the United States. 70 - 85% of the mortality occurs in people over the age of 65. Influenza vaccination is the best protection against the virus, but it is less effective for the elderly, which may be in part due to differences in the quantity or type of B cells induced by vaccination. To investigate this possibility, we sorted pre- and post-vaccination peripheral blood B cells from three young and three older adults with strong antibody responses to the inactivated influenza vaccine and employed single-cell technology to simultaneously profile the gene expression and the B cell receptor (BCR) of the B cells. Prior to vaccination, we observed a higher somatic hypermutation frequency and a higher abundance of activated B cells in older adults than in young adults. Following vaccination, young adults mounted a more clonal response than older adults. The expanded clones included a mix of plasmablasts, activated B cells, and resting memory B cells in both age groups, with a decreased proportion of plasmablasts in older adults. Differential abundance analysis identified additional vaccine-responsive cells that were not part of expanded clones, especially in older adults. | ||||||

SDY2963: A multivalent nucleoside-modified mRNA vaccine against all known influenza virus subtypes | |||||||
Status: | Updated | ||||||
Description: | Seasonal influenza vaccines offer little protection against pandemic influenza virus strains. It is difficult to create effective prepandemic vaccines because it is uncertain which influenza virus subtype will cause the next pandemic. In this work, we developed a nucleoside-modified messenger RNA (mRNA)-lipid nanoparticle vaccine encoding hemagglutinin antigens from all 20 known influenza A virus subtypes and influenza B virus lineages. This multivalent vaccine elicited high levels of cross-reactive and subtype-specific antibodies in mice and ferrets that reacted to all 20 encoded antigens. Vaccination protected mice and ferrets challenged with matched and mismatched viral strains, and this protection was at least partially dependent on antibodies. Our studies indicate that mRNA vaccines can provide protection against antigenically variable viruses by simultaneously inducing antibodies against multiple antigens. | ||||||
