Background
Conventional basophil activation tests (BATs) measure basophil activation by the increased expression of CD63. Previously, fluorophore‐labeled avidin, a positively‐charged molecule, was found to bind to activated basophils, which tend to expose negatively charged granule constituents during degranulation. This study further compares avidin versus CD63 as basophil activation biomarkers...
Background
The impact of exposure to air pollutants, such as fine particulate matter (PM), on the immune system and its consequences on pediatric asthma, are not well understood. We investigated whether ambient levels of fine PM with aerodynamic diameter ≤2.5 microns (PM2.5) are associated with alterations in circulating monocytes in children with or without asthma.
Methods
Monocyte phenotyping...
Background
Oral immunotherapy (OIT) is frequently discontinued due to adverse events (AEs) and current data suggests that lowering OIT doses can minimize severity and frequency of AEs. However, the minimum daily dose that can enable desensitization and induce immune responses in multi‐food OIT (mOIT) is unknown.
Methods
Participants aged 2–25 years with multi‐food allergies were pretreated with...
Background
It is unclear whether asthma and its allergic phenotype are risk factors for hospitalization or severe disease from SARS‐CoV‐2.
Methods
All patients over 28 days old testing positive for SARS‐CoV‐2 between March 1 and September 30, 2020, were retrospectively identified and characterized through electronic analysis at Stanford. A sub‐cohort was followed prospectively to evaluate long‐term...
