Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will use the collected cells to obtain pediatric HAE cultures. We will use these cultures as an ex vivo model to study NETs induced changes in the context of RSV infection of the pediatric airways. We will perform measurements on airway mucus (protein expression) and airway epithelial damage (necrosis, apoptosis, loss of differentiation, loss of barrier function, apoptotic gene expression, inflammation markers and inflammatory pathways). | — |
