Schistosomes are blood flukes that ingest large amounts of host blood during their intra-mammalian stage. The ingested blood contains leukocytes that can be harmful, yet the parasites survive inside the host for decades, reflecting superb immune evasion mechanisms that remain poorly understood. Our previous work discovered that FoxA, a forkhead transcription factor, drives the production of the esophageal gland, an anterior digestive organ essential for degrading the ingested leukocytes and for survival.

Germ cells are regulated by local microenvironments (niches), which secrete instructive cues. Conserved developmental signaling molecules act as niche-derived regulatory factors, yet other types of niche signals remain to be identified. Single-cell RNA-sequencing of sexual planarians revealed niche cells expressing a nonribosomal peptide synthetase ().

Background: The composition of the gut microbiome has been associated with development of atopic conditions such as food allergy (FA) and asthma. African American or Black children with FA have higher rate of asthma compared to their White counterparts.

Objective: We sought to investigate whether the diversity and relative abundance (RA) of gut microbiota is different between children with FA from different racial backgrounds living in the same cities.

Article Synopsis
  • A study examined the difference in atopic comorbidities, such as asthma and allergic rhinitis, between Black and White children with food allergies, finding that Black children have a higher risk.
  • Researchers used a comprehensive area deprivation index (ADI) to assess the influence of socioeconomic status on these health disparities.
  • The results indicated that while neighborhood socioeconomic deprivation is linked to asthma and allergic rhinitis, Black children still faced a greater risk for asthma even after accounting for SES factors.
