Interaction between CD154 (CD40 ligand) on activated T lymphocytes and its receptor CD40 has been shown to be critically involved in the generation of cell-mediated as well as humoral immunity. CD40 triggering activates dendritic cells (DC), enhances their cytokine production, up-regulates the expression of costimulatory molecules, and induces their maturation. It is unknown how stimulation of ...
BACKGROUND The CC-chemokine receptor-3 (CCR3) has emerged as a target molecule for pharmacological intervention in allergic inflammation. OBJECTIVE To examine whether a dual CCR3 and H1-receptor antagonist (AZD3778) affects allergic inflammation and symptoms in allergic rhinitis. METHODS Patients with seasonal allergic rhinitis were subjected to three seven days' allergen challenge series. ...
Recent advances in understanding the cellular and molecular mechanisms of atopy have shed light on potential targets for the development of new therapies for allergic diseases. In this issue of the JCI, Seshasayee et al. provide direct in vivo evidence that OX40 has critical roles in allergic inflammation mediated by thymic stromal lymphopoietin (TSLP) (see the related article beginning on page...
Phosphodiesterase 3 (PDE3) and PDE4 regulate levels of cyclic AMP, which are critical in various cell types involved in allergic airway inflammation. Although PDE4 inhibition attenuates allergic airway inflammation, reported side effects preclude its application as an antiasthma drug in humans. Case reports showed that enoximone, which is a smooth muscle relaxant that inhibits PDE3, is benefici...
Thymic stromal lymphopoietin (TSLP) is a cytokine expressed by epithelial cells, including keratinocytes, and is important in allergic inflammation. Allergic skin inflammation elicited by epicutaneous immunization of mice with ovalbumin (OVA), a potential model of atopic dermatitis, was severely impaired in TSLPR(-/-) mice, as evidenced by decreased infiltration of eosinophils and decreased loc...
To gain more insight into the mechanisms of particulate matter (PM)-induced adjuvant activity, we studied the kinetics of airway toxicity/inflammation and allergic sensitization to ovalbumin (OVA) in response to ultrafine carbon black particles (CBP). Mice were exposed intranasally to OVA alone or in combination with different concentrations of CBP. Airway toxicity and inflammation were assesse...
The epithelial-derived cytokine thymic stromal lymphopoietin (TSLP) has been associated with the promotion of type 2 inflammation and the induction of allergic disease. In humans TSLP is elevated in the lungs of asthma patients and in the lesional skin of individuals with atopic dermatitis, whereas mice lacking TSLP responses are refractory to models of Th2-driven allergic disease. Although sev...
