sub-jects after in vitro stimulation with inflammatory cyto-kines . It has also been observed that monocyte-de-rived dendritic cells induced from patients with pollino-sis could produce higher levels of MDC by stimulation with specific antigen through the enhancement of MDC mRNA expression . Immunohistochemical analysis of nasal biopsy samples showed TARC immunoreactivity in Rivaroxaban nasal epithelium . These reports suggest that TARC and MDC may be strongly involved in the development Taurine inhibitor and maintenance of allergic diseas including atopic dermatitis and allergic rhinitis. Therefo the present re-sults showing the suppressive activity of the second-gen-eration antihistamin especially F on TARC and MDC production may be interpreted as demonstrating that these antihistamines decrease the recruitment of T -type T cells to the site of allergic inflammation through the suppression of TARC and MDC production and reduce disease severity after antigenic stimulation in vivo.
This may be supported by the observation that a monoclonal antibody against TARC could prevent air-way hyperresponsiveness induced by antigenic stimula-tion in a murine asthma model . Other observations Rutin 153-18-4 showing the inhibitory action of a polyclonal antibody against mouse MDC on airway hyperresponsiveness and lung inflammation induced by provocation with ovalbu-min when the antibody was administered to mice sensi-tized with ovalbumin also support our speculation .
