Article Synopsis
  • The study investigates the unexplored variations in DNA methylation at CpG sites in airway epithelial cells from children with and without allergic asthma, using whole-genome bisulfite sequencing.
  • Researchers designed a custom array to highlight these high-value CpGs and used it alongside existing arrays to analyze allergic sensitization in children from different birth cohorts.
  • Results showed that the custom array contained CpGs with intermediate methylation levels, which were significantly associated with allergic sensitization and gene expression regulation.

Rhinovirus causes many types of respiratory illnesses, ranging from minor colds to exacerbations of asthma. is an opportunistic pathogen that is increased in abundance during rhinovirus illnesses and asthma exacerbations and is associated with increased severity of illness through mechanisms that are ill-defined. We used a co-infection model of human airway epithelium differentiated at the air-liquid interface to test the hypothesis that rhinovirus infection promotes adhesion and survival on the respiratory epithelium.

Background: Asthma is the most common chronic disease in children, occurring at higher frequencies and with more severe disease in children with African ancestry.

Methods: We tested for association with haplotypes at the most replicated and significant childhood-onset asthma locus at 17q12-q21 and asthma in European American and African American children. Following this, we used whole-genome sequencing data from 1060 African American and 100 European American individuals to identify novel variants on a high-risk African American-specific haplotype.

In the interest of advocating for the postdoctoral community in the United States (US), we compared the results of surveys of postdocs carried out in 2019 and in late 2020. We found that respondents' mental health and wellness were significantly impacted by the pandemic irrespective of their gender, race, citizenship, or other identities. Career trajectories and progression were also affected, as respondents reported being less confident about achieving career goals, and having more negative perceptions of the job market compared to before the pandemic.

Background: Genome-wide association studies (GWASs) have identified thousands of variants associated with asthma and other complex diseases. However, the functional effects of most of these variants are unknown. Moreover, GWASs do not provide context-specific information on cell types or environmental factors that affect specific disease risks and outcomes.
