- Subjects who the investigator believes can and will comply with the requirements of the protocol.
- Written informed consent obtained from the subject.
- Healthy subjects (except the condition studied in the ALLERGY group).
- A male or female between, and including 18 and 45 years of age at the time of study start.
- Subject presenting moderate to severe clinical symptoms of allergy within the week before enrolment (only for ALLERGY group).
- Subjects suffering from seasonal allergy to birch pollen previously documented by a medical history (only for ALLERGY group).
- A positive skin prick test response realised and/or a positive test for specific IgE against birch within the last 5 years (only for ALLERGY group).
Exclusion Criteria:
- Any known or clinical signs of anaemia or any condition that would preclude the drawing of blood as described in the protocol.
- Receipt of blood products 120 days prior to study visit.
- Receipt of immunoglobulin 120 days prior to study visit.
- Use of any investigational or non-registered product within 30 days preceding the study visit.
- Concurrently participating in another clinical study, at the time of the study visit, in which the subject has been or will be exposed to an investigational or a non-investigational product.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history.
- Any confirmed or suspected autoimmune or inflammatory disorders.
- Administration of systemic or inhaled anti-inflammatory medications and, in particular, inhaled corticoid-steroids and cromoglycates within 30 days preceding the study visit. Purely local medications such as intranasal steroids or systemic symptomatic medications such as antihistamines and beta agonists are allowed.
- Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the study visit.
- Pregnant or lactating female.
- Any past or current birch-specific immunotherapy (only for ALLERGY group).
- Any allergic disease as established by medical history before study start (only for CONTROL group).
- Family history of allergic diseases in the first degree family members (only for CONTROL group).

Number of Subject Responders With Antigen Specific Lymphocytes T Helper 2 (Th2) Cluster of Differentiation 4+ (CD4+) T Cells Expressing Cytokines
기간: At Day 0
|
Among cytokines expressed were interleukin-4 (IL-4), interleukin-5 (IL-5) and/or interleukin-13 (IL-13), as measured by flow cytometry and multiplex assays. Responders were defined as subjects with a concentration after Bet v 1 stimulation above Percentile 95 (P95) (determined on Betula verucossa 1[Bet v 1] Bromodeoxyuridine + [BrdU+] subjects) of all concentrations after medium only stimulation |

Among cytokines expressed were IL-4, IL-5 and/or IL-13, as measured by flow cytometry and multiplex assays. Responders to a specific cytokine were defined as subjects with concentration for that respective cytokine after Bet v 1 stimulation above P95 of the concentration for that cytokine after medium only stimulation for all subjects (Total cohort), AND at least 5 times higher than their own respective concentration after medium only stimulation. |
