Om het menselijk rhinovirus model op te zetten in ons centrum, gebruik makend van HRV serotype 16 (HRV-16) |
|
E.2.2 | Secondary objectives of the trial |
To determine:
1. The viral load of HRV-16 infection in nasal washes
2. The incubation period of HRV-16 infection.
3. The effects of HRV-16 infection on cold symptoms, temperature, and spirometry.
4. Suitable inflammatory parameters (and their kinetics) that play a role in the HRV-16-induced local inflammatory response
5. Whether HRV-16 infection can induce a systemic immune response and its kinetics
6. The effect of HRV-16 seropositivity on the clinical and immunological response to re-infection with HRV-16.
7. If a subject is protected against re-infection with HRV-16 within one week (tolerance formation to HRV), and if so which mechanisms play a role (local and systemic)
8. Whether HRV-16 infection modulates the immune response of circulating leukocytes by measuring the cytokine response, of leukocytes ex vivo stimulated with different inflammatory stimuli.
9. The relationship of the nasal and gut microbiota on HRV-16 (re-)infection and vice-versa.
